Can AI Videos Replace In-Person Physical Therapy?

By Crystal Lindell

A UK-based technology company claims their Artificial Intelligence (AI) videos are good enough to replace in-person physical therapy for some back pain patients. 

Like the United States, the waiting time in the UK to see a medical specialist can be daunting. According to the UK’s National Health Service (NHS), the average wait time after a referral for simple back or spine pain is more than 18 weeks. Nearly 350,000 people in England were on waiting lists for treatment for musculoskeletal problems last year. 

But in a pilot study of over 2,500 NHS patients who used a physiotherapy (physical therapy) app operated by Flok Health, the waiting times were cut in half. 98% of referred patients continued watching the AI powered videos, while only 2% required or requested a transfer to traditional to face-to-face care with a therapist.

The app works by showing patients pre-recorded videos of actual human instructors, but then tailors the video clip order based on how AI interprets responses from the patient. 

“Each appointment is like a 30 minute video call, except our side of the call is created by our AI engine in real-time, just for you,” Flok Health explains on its website. “You can answer questions and your digital physio will respond to you live, in a continuously generated personal video stream.”

Patients are also prescribed a set of exercises for the coming week before the next appointment. Flok Health says the exercises are specifically selected based on “a detailed analysis of symptoms and movement patterns.” The app also guides patients through practicing their exercises between appointments, and helps them see their progress and stay on track.

Patients also have access to human physiotherapists and doctors. The company said they monitor patient recovery remotely and can arrange to speak to a patient if they have questions. 

The BBC's Scott Nover tried the app back in March and wrote about his experience with an AI generated physical therapist named “Kirsty.” He found her recommendations lacking, with his main complaint being that Kirsty wasn’t able to correct his form in real time like a live therapist would.

“The big difference here is that Kirsty can't see me. Her pre-recorded videos don't watch my movements and stretches. They rely on me following her instructions correctly and reporting if something is amiss,” Nover wrote.

“My back felt better after my sessions with Flok, but the app likely isn't for me. I'm clumsy and uncoordinated and need someone watching my form at all times – if not, I'm likely to hurt myself further.”

However, I could see a near-future scenario where AI is able to analyze patient form in real-time with technology that’s similar to that used in gaming counsels like XBox Kinect. 

Nover also pointed to a 2024 study for a similar AI-powered back pain treatment called selfBACK that found patients were unlikely to use it. Nearly one-third of patients never accessed the app, and another third rarely used it. 

It’s definitely easier to blow off an app than it is to blow-off an in-person physical therapy appointment with an actual human being, so those results make sense. 

As a patient, I’ve had both in-person physical therapy referrals given to me sometimes, and links to relevant videos with accompanying handouts provided to me at other times. 

To be frank, this Flok Health app sounds a lot like that latter. And I will confess that I was a lot less likely to follow a physical therapy treatment plan when it didn’t involve an actual physical therapist.

At the same time, at least in the United States, physical therapy can be very expensive, especially when there’s a high co-pay for each session. So having less expensive treatment options is a good thing. Although it’s unclear when Flock might be widely available to U.S. patients.

I’m skeptical that AI will be fully replacing physical therapists any time soon, but it sounds like tech companies are hoping they can make a massive dent in their client base and waiting times..

Learn the Latest Advances in Adhesive Arachnoiditis at a Free Seminar

By Pat Anson

If you suffer from adhesive arachnoiditis (AA) or would like to learn more about it, there’s a unique opportunity next month to learn about the latest research and treatments for AA, and to connect with other patients, advocates and physicians.

The Tennant Foundation and the Arachnoiditis & Chronic Meningitis Collaborative Research Network (ACMCRN) are hosting a one-day seminar on Saturday, August 16 in Westminster, Colorado outside Denver. Lodging, meals and transportation are not provided, but the conference itself is free of charge.

AA is a spinal disease that causes chronic inflammation in the arachnoid membrane that covers the spinal canal. When nerves in the spine also become inflamed, they can adhere or stick together, causing severe pain and a wide variety of other symptoms.  

AA can develop after surgery or trauma that damages the spine. It may also be triggered by an inflammatory autoimmune disease that originates outside the spine that spreads into spinal tissue.

There is no cure for AA, but advances are being made in its treatment. The problem is that few practitioners know how recognize the early symptoms of AA, much less how to diagnose and treat it. That’s why conference organizers hope physicians will attend, along with patients, caregivers and family members.   

“We'll take whoever is interested,” says Dr. Forest Tennant, who is recognized as the world’s leading expert in AA. “We'd like to have many nurse practitioners or physicians who really want to know the disease. We're going to cover it backwards and forwards. We hope to make them educators and advocates for the disease.”  

Tennant has developed a unique protocol to treat AA not only with pharmaceuticals, but with hormones, vitamins and supplements that can help ease the symptoms and slow or prevent the disease from spreading.

“I want to get across the point that treating arachnoiditis is no more difficult than treating emphysema or rheumatoid arthritis or high blood pressure. It can be done in a primary care setting quite easily. It is not something that has to be done at the Mayo Clinic or in a sophisticated medical setting. It can be done in any office,” says Tennant.

Also speaking at the conference is Eve Blackburn, VP of Patient Engagement for ACMCRN, who will talk about the resources her organization has for patients, including a list of physicians that treat AA.  

“I’ll be sharing an update on the relaunch of the International Arachnoiditis Patient Registry, which is currently undergoing final steps in the ethics review process. We anticipate reopening within the next two months through our new secure platform, Digital Cabinet. I’ll also highlight our growing peer support programs, our referral list of Arachnoiditis-aware physicians, and the wide range of educational resources available at acmcrn.org,” said Blackburn.

The conference is not just for people diagnosed with AA. Since the disease is often associated with autoimmune disease or other types of spinal problems, patients suffering from those conditions could also learn important lessons at the seminar.  

“I call them associated diseases. Ehlers-Danlos syndrome, Tarlov cyst, and the Epstein Barr virus, those three in particular, as well as other spinal conditions. You can't talk about arachnoiditis unless you're also talking about autoimmunity and these other conditions that are high risk factors for developing the disease,” says Tennant.

The August 16 seminar is being held at the Marriott Hotel in Westminster, Colorado — which a special rate for conference attendees. Click here for more details.

You can also visit the conference website for hotel information and list of phone numbers to call if you have any questions. All attendees are encouraged to register by August 1.

5 Cool Things to Help You Endure Summer Heat With Chronic Pain

By Crystal Lindell

As temperatures heat up this summer, it can be difficult to get through hot sunny days when you’re also dealing with chronic pain and chronic illness. 

Weather is such a huge factor in the severity of day-to-day chronic pain levels, and if you’re on certain medications heat can also impact your body in other ways, like skin irritation and ankle swelling. 

Here are 5 things I use to get through the summer months while also dealing with chronic pain and chronic illness. 

Gold Bond Friction Defense Stick

My number one summer survival item is the Gold Bond Friction Defense Stick. I use it on my arms and thighs to prevent the heat and humidity from chaffing my skin if I’m wearing shorts, a tank top, a bathing suit or any light summer clothing. 

And this stuff seriously works! Putting it on after my morning shower makes such a huge difference in my quality of life throughout the summer. 

If you have a long day of walking, or swimming you may need to re-apply a few times, but for most day-to-day activities, I have found that once in the morning is more than adequate. 

Find it on Amazon here.

Compression Socks

Every summer my excessive ibuprofen use combines forces with my Ehler-Danlos Syndrome to make my ankles swell up – especially if the humidity is high.

So I swear by these compression socks, which virtually eliminate that symptom, even after long car rides. I have multiple packs of these in multiple colors, and throughout the summer months, I wear them almost daily. 

No, they aren’t super stylish with shorts, but if you wear them underneath pants, nobody can even tell. 

Find them on Amazon here. 

Light, Airy Pants

Speaking of pants, I tend to prefer them to shorts most of the time, even in the summer months. And these light, airy pants are great for enduring the heat. 

They offer all the comfort of pants, with all the breathability of shorts. I use them as pajamas, as well as pants to wear over my bathing suit at the pool, and even for lounging around during the day.

According to my Amazon order history, I have literally ordered these pants eight times! I have them in every color and even in multiple sizes. They’re also great at enduring weight fluctuations that are common when you’re on a lot of medications and dealing with chronic pain because of how stretchy the waist is. 

But the best things about these pants might be that they have pockets! If you’re familiar with the world of women’s pants, you know just how valuable and rare that feature is! 

Find them on Amazon here. 

Adjustable Fan

Sometimes chronic pain and related medications make us especially sensitive to heat and humidity, but a personal, adjustable fan can be a great way to cope. 

We have this fan in multiple colors, and we use them throughout the summer to direct air flow exactly where we want it. 

It’s relatively quiet for a fan, but it still packs a punch when it comes to cooling you off during the summer months. 

Find it on Amazon here. 

Summer Reading Club

If you’re looking for a comforting summer read, I can’t recommend “Garden Spells” by Sarah Addison Allen enough. It’s a very light, easy read that follows the stories of two sisters who have to navigate common sibling friction with the added stress of coming from a magical family that the whole town thinks is “weird.”

I read it for a book club recently and flew through it in two days. It’s a great light read, even if you’re have a chronic pain flare and can’t get off the couch. It also takes place in the south, and the heat is a common theme, making it perfect for getting into the summer state of mind.

Flexible Implant Could Be Alternative to Spinal Cord Stimulators

By Pat Anson

Spinal cord stimulators have long been fraught with problems. First developed in the 1960’s, the devices are surgically implanted near the spine to deliver mild electric impulses that block pain signals from traveling to the brain.

Although their design and technology have improved over the years, making them smaller, rechargeable and programmable, spinal cord stimulators (SCSs) still have high failure rates and poor safety records. Recent studies have also questioned their effectiveness in treating back pain.

Researchers at the University of Southern California have developed an alternative: a small, flexible, wireless, and battery-free implant that could overcome some of the limitations of SCSs.

NATURE ELECTRONICS

The experimental device, recently introduced in a paper published in Nature Electronics, is powered by a wearable ultrasound transmitter and uses machine learning algorithms to customize treatment for each patient. The implant is designed to bend and twist, unlike traditional stimulators that tend to be bulky and are hard-wired to batteries.

“Implantable percutaneous electrical stimulators… are expensive, can cause damage during surgery and often rely on a battery power supply that must be periodically replaced. Here we report an integrated, flexible ultrasound-induced wireless implantable stimulator combined with a pain detection and management system for personalized chronic pain management," wrote a team of researchers at USC’s Alfred E. Mann Department of Biomedical Engineering.

The researchers tested the wireless stimulator in laboratory rodents experiencing different levels of pain. They found the device accurately predicted the levels of stress experienced by the animals and adapted the electrical stimulation it delivered, easing most of their pain.

“We classify pain stimuli from brain recordings by developing a machine learning model and program the acoustic energy from the ultrasound transmitter and, therefore, the intensity of electrical stimulation," researchers said. "The implant can generate targeted, self-adaptive and quantitative electrical stimulations to the spinal cord according to the classified pain levels for chronic pain management in free-moving animal models."

The research team is planning further tests on other lab animals, with the goal of eventually testing the device in clinical trials on humans.

About 50,000 traditional spinal cord stimulators are implanted every year in the U.S., where they are promoted as alternatives to opioids and other pain treatments. However, a 2022 study found that SCSs do not reduce patient use of opioids, epidurals, steroid injections or radiofrequency ablation. About a fifth of patients experienced complications so severe the devices had to be removed or revised.

The Two Most Common Causes of Adhesive Arachnoiditis

By Dr. Forest Tennant

Adhesive arachnoiditis (AA) doesn’t just happen out-of-the-blue or overnight. It is the tragic end result of sequential pathologic damage, over time, to multiple spinal tissues.

AA may develop from a direct spinal injury or from an inflammatory, autoimmune disease that originates outside the spine.  The discovery that inflammatory-autoimmune diseases can originate outside the spine and spread into spinal tissue is a new medical concept.

Here are the two common pathologies that can cause AA, and the early symptoms that precede AA itself:

Pathology #1: Spinal Trauma

The first pathologic journey is accidental spine trauma or a medical procedure such as an epidural injection that damages the spinal canal cover, which consists of an outer layer (dura) and an inner layer (arachnoid).

Direct spinal injuries may occur to persons in good health.  Examples are auto accidents or electrocution in an industrial accident. The arachnoid layer becomes inflamed after trauma, just like a finger that has been hit with a hammer. The inflammation may progress and then spread.

Eventually, the inflammation will contact cauda equina nerve roots and spread into them. After a time ranging from weeks to months, the inflammatory adhesions “glue” cauda equina nerve roots to the arachnoid, forming the disease called adhesive arachnoiditis.

Pathology #2: Degenerative Discs

Spinal discs degenerate when they become inflamed, due to a pathologic generator such as an infection, autoimmunity or trauma.

Persons who have a genetic connective tissue disease like Ehlers-Danlos, a spine anatomic abnormality, or an autoimmune disease are at high risk to develop degenerative disc disease. Once inflammation sets in, the disc softens, shrinks and slips out of its space, pressing against the spinal canal cover (dura and arachnoid layers).

The inflammation in the disc may spread to the arachnoid membrane and cauda equina nerve roots. As stated in Pathology #1, when inflammation produces sticky adhesions in the cauda equina nerve roots and arachnoid, they may glue together forming AA.

Early Symptoms

If the arachnoid becomes inflamed after trauma, epidural injection, spinal puncture or surgical procedure, there will be headaches, localized back pain, feverishness and dysphoria (a state of unease, depression and fatigue). This usually starts 7 to 10 days after the procedure or trauma.

When the cauda equina also becomes inflamed, the first early symptoms are shooting pains into the buttocks and legs, burning feet, and the tingling sensation of water or insects on the buttocks or legs.

Prevention of AA may be possible in these circumstances by use of one or more anti-inflammatory drugs that are effective inside the spinal canal. You can learn more about the symptoms and treatments for AA on our website.

Pain Clinic CEO Faced 20 Years for Fraud. He Got 18 Months.

By Brett Kelman, KFF Health News

Federal prosecutors sought a maximum prison sentence of nearly 20 years for the CEO of Pain MD, a company found to have given hundreds of thousands of questionable injections to patients, many reliant on opioids. It would have been among the longest sentences for a health care executive convicted of fraud in recent years.

Instead, he got 18 months.

Michael Kestner, 73, who was convicted of 13 fraud felonies last year, faced at least a decade behind bars based on federal sentencing guidelines.

He was granted the substantially lightened sentence due to his age and health Wednesday during a federal court hearing in Nashville.

U.S. District Judge Aleta Trauger described Kestner as a “ruthless businessman” who funded a “lavish lifestyle” by turning medical professionals into “puppets” who pressured patients into injections that did not help their pain and sometimes made it worse.

“In the court’s eyes, he knew it was wrong, and he didn’t really care if it was doing anyone any good,” Trauger said.

MICHAEL KESTNER

But Trauger also said she was swayed by defense arguments that Kestner would struggle in federal prison due to his age and medical conditions, including the blood disorder hemochromatosis. Trauger said she had concerns about prison health care after considering about 200 requests for compassionate release in other court cases.

“The medical care at these facilities,” defense attorney Peter Strianse said, “has always been dodgy and suspect.”

Kestner did not speak at the court hearing, other than to detail his medical conditions. He did not respond to questions as he left the courthouse.

‘Human Pin Cushions’

Pain MD ran as many as 20 clinics in Tennessee, Virginia, and North Carolina throughout much of the 2010s. While many doctors were scaling back their use of prescription painkillers due to the opioid crisis, Pain MD paired opioids with monthly injections into patients’ backs, claiming the shots could ease pain and potentially lessen reliance on pills, according to federal court documents.

During Kestner’s October trial, the Department of Justice proved that the injections were part of a decade-long scheme that defrauded Medicare and other insurance programs of millions of dollars by capitalizing on patients’ dependence on opioids.

The DOJ successfully argued at trial that Pain MD’s “unnecessary and expensive injections” were largely ineffective because they targeted the wrong body part, contained short-lived numbing medications but no steroids, and appeared to be based on test shots given to cadavers — people who felt neither pain nor relief because they were dead. During closing arguments, the DOJ argued Pain MD had turned some patients into “human pin cushions.”

“They were leaned over a table and repeatedly injected in their spine,” federal prosecutor Katherine Payerle said during the May 14 sentencing hearing. “Over and over, month after month, at the direction of Mr. Kestner.”

At last year’s trial, witnesses testified that Kestner was the driving force behind the injections, which amounted to roughly 700,000 shots over about eight years, with some patients receiving up to 24 at once.

Four former patients testified that they tolerated the shots out of fear that Pain MD otherwise would have cut off their painkiller prescriptions, without which they might have spiraled into withdrawal.

One of those patients, Michelle Shaw, told KFF Health News that the injections sometimes left her in so much pain she had to use a wheelchair. She was outraged by Kestner’s sentence.

“I’m disgusted that all they got was a slap on the wrist as far as I’m concerned,” Shaw said May 14. “I hope karma comes back to him. That he suffers to his last breath.”

Drugs Targeting ‘Zombie Cells’ May Reduce Low Back Pain

By Pat Anson

Low back pain is one of the most common and difficult pain conditions to treat. Although it’s the leading cause of disability worldwide, a recent study found that only about 10% of pharmaceutical and non-surgical therapies for low back pain provide relief. More invasive treatments, such as spinal injections and nerve blocks, have also been found to be no more effective than a placebo.

In short, there’s not much evidence to support the use of many treatments commonly used for low back pain -- which makes a preclinical study on two potential treatments all the more interesting.

Low back pain is commonly caused by senescent cells, so-called “zombie cells” that build up in spinal discs as people age or when discs are damaged. Instead of dying off like normal cells, these aging cells linger in the spine, causing pain and inflammation.

In experiments on laboratory mice, researchers at McGill University found that two drugs – o-vanillin and RG-7112 -- can clear zombie cells from the spine, reduce pain and improve bone quality. O-vanillin is a natural compound, while RG-7112 is an FDA-approved cancer drug that shrinks tumors.

“Our findings are exciting because it suggests we might be able to treat back pain in a completely new way, by removing the cells driving the problem, not just masking the pain,” said senior author Lisbet Haglund, PhD, a Professor in McGill’s Department of Surgery and Co-director of the Orthopaedic Research Laboratory at Montreal General Hospital.

Haglund and her colleagues found that o-vanillin and RG-7112 had a beneficial effect when taken separately, but their impact was greatest when they were taken together orally.  After just eight weeks of treatment, the drugs slowed or even reversed disc damage in mice.  

“We were surprised that an oral treatment could reach the spinal discs, which are hard to access and present a major hurdle in treating back pain,” said Haglund. “The big question now is whether these drugs can have the same effect in humans.”

O-vanillin belongs to a family of spicy and pungent natural compounds known as vanilloids, which are found in chili peppers and turmeric. Vanilloids are already used to control inflammation and reduce pain in topical patches like Qutenza.

O-vanillin was not originally intended to be part of the McGill study. But while testing other drugs, researchers decided to include o-vanillin to see whether it might be effective when taken orally. The results offer some of the first evidence that o-vanillin can clear out zombie cells. Analogs of RG-7112 were already known to do this in osteoarthritis and cancer research, but had not previously been used to treat back pain.

The McGill findings are published in the journal Science Advances. In future studies, Haglund’s team hopes to modify o-vanillin to help it stay in the body longer and become more effective. In addition to back pain, they believe the two drugs have the potential to treat other age-related diseases driven by senescent cells, such as arthritis and osteoporosis.

Mindfulness and Cognitive Behavioral Therapy Reduce Chronic Low Back Pain

By Pat Anson

Have you tried cognitive behavioral therapy (CBT) or mindfulness? Did they help relieve your pain?

Chronic pain sufferers have been telling us for years that neither form of psychotherapy worked for them. Yet many physicians continue to recommend CBT and/or mindfulness as a safer alternative to opioids and other pain medications.

Does either therapy actually work? And, if so, which one works better?

In the largest head-to-head study of its kind, a team of researchers compared the effectiveness of CBT with mindfulness in 770 patients with chronic low back pain. Unlike previous studies, these patients had fairly high pain levels (an average of 6.1 on a zero to 10 pain scale) and they were taking opioids for at least three months.

The study wasn’t short-term either. Participants were regularly surveyed about their pain levels, physical function, quality of life, and opioid use for up to a year.     

“The people in this study had quite severe back pain that interfered with their life and was bad enough to need opioid medication. Usually, in that condition, people don’t really get better over time on their own,” said co-lead author Bruce Barrett, MD, a Professor of Family Medicine and Community Health at the University of Wisconsin-Madison.

Participants were divided into two groups and trained by experienced therapists in either mindfulness or CBT, before being told to practice them at home daily for at least 30 minutes. Patients trained in mindfulness learned how to “deconstruct” their pain to make it seem less important, while those trained in CBT learned coping, behavioral and relaxation skills.

The study findings, published in JAMA Network Open, show that CBT and mindfulness were equally effective, leading to modest improvements in pain, function and quality of life. The benefits persisted and grew stronger over 12 months, with most participants reducing or even stopping their opioid use.

After a year, the average pain level in the mindfulness group fell to 5.4, while those in the CBT group were reduced to 5.5 on the zero to 10 scale. That’s about a 10% improvement.

“Both mindfulness and cognitive behavioral therapy were shown to be safe, effective treatments, providing lasting benefits for people with opioid-treated chronic back pain. These evidence-based behavioral therapies should be standard of care available to our patients,” wrote lead author Aleksandra Zgierska, MD, a Professor of Family and Community Medicine at Penn State College of Medicine.

Although participants were not explicitly encouraged to reduce their use of opioids, patients in both groups did. Researchers say that was a direct result of their training, which taught them how to cope better with pain and decrease their opioid use on their own.

“These therapies aren’t a total cure, but they teach people how to develop the inner resources they need to cope with chronic pain and to live a better life,” said co-author Eric Garland, PhD, a Psychiatry Professor at the University of California San Diego. “Mindfulness is a self-regulated tool that comes from within, unlike surgery or medication where something is being done to you from the outside. By learning these techniques, patients continue to experience lasting benefit,”

A recent study at UC San Diego using advanced brain imaging found some of the first physical evidence that mindfulness lowers pain intensity by reducing neural activity in parts of the brain associated with pain and negative emotions.

How Chronic Pain Impacts Romantic Relationships

By Crystal Lindell

The more you love someone with chronic pain, the more likely it is that their pain will cause you emotional distress. 

That’s according to new research published in the Journal of Health Psychology, which looks at the ways middle-aged romantic partnerships are impacted when one person has chronic pain. 

The researchers collected twice-daily surveys over the span of 30 days from 147 couples who were at least 50 years of age and had one partner who suffered from chronic back pain. 

Using the couples' answers to questions about distress and relationship closeness, as well as reports of pain severity from the pain-affected partner, they examined how emotional, behavioral and cognitive closeness affected the quality of couples’ daily interactions.

On the positive side, researchers found that emotional closeness between couples dealing with chronic pain led to more marital satisfaction on days when the couple felt close. 

However, on the other side of things, the closer the couple felt emotionally on any given day, the more likely it was that the non-pain partner experienced more distress. The non-pain partner apparently feels empathy for the pained partner, which results in them feeling stressed. 

As anyone who’s ever been in love knows, empathy is the required price. When your partner is sad, you will also tend to be sad on their behalf. 

This is not inherently a bad thing. Feeling empathy for your partner when they are dealing with pain makes it more likely that you’ll work harder to ease their pain, by doing things like advocating for them in healthcare settings and allowing them to rest while you do the household chores. 

The researchers framed this as something to avoid though, which I guess makes sense if it’s happening excessively.

“Couples have to find a balance that is ideal for them in managing closeness versus independence — this is true for all couples, not just those dealing with the impacts of chronic pain. But for those dealing with chronic pain, we can help them learn how to balance the benefits of closeness with minimizing shared distress stemming from a chronic condition,” lead researcher Lynn Martire, PhD, a professor of human development and family studies at Penn State’s Center for Healthy Aging, said in a press release.: 

The findings suggest that methods could be developed to help couples find the right balance in closeness, which would protect them from causing more pain and distress for each other. Martire and her colleagues plan further studies on the roles of behavioral and cognitive closeness.

“I’m excited to dive deeper into the other research questions we can examine from this data set,” Martire said. “We gathered data using different measures of relationship closeness, how they differ between patients and partners and how relationship closeness changes over time. We are poised to learn a great deal about the impact of pain on couples.”

Prior studies show that closeness is associated with many positive and beneficial relationships, including higher levels of commitment and satisfaction, and a lower risk of the relationship ending. 

However, researchers also say their findings suggest that too much closeness may transfer negative emotions and physical symptoms between partners.

“These findings illustrate a complex interplay between closeness and personal well-being in couples managing chronic illness and suggest the need for interventions that target both the benefits and potential costs of closeness,” they concluded. 

Yes, indeed, there are “benefits and potential costs” in any close relationship. It’s a contradiction that countless poets have spent centuries trying to navigate. 

Love comes at a price, but most of the time, the price is worth it. 

Most Treatments for Low Back Pain Don’t Work

By Crystal Lindell

While I’ve struggled with relatively mild lower back pain for years now, a few months ago I threw my back out for the first time. I literally could not get out of bed on my own, and I spent almost a week on the couch recovering while my lower back spasmed. 

It was horrible, and even my usual pain relief methods and doses of pain meds did not help much. In the end, for me, it was mostly just time and rest that seemed to help the most. 

Now a new study confirms just how difficult it is to treat low back pain. 

In fact, only about 10 percent of treatments for low back pain actually work, according to new research published this week in the journal BMJ Evidence-Based Medicine. 

The study by an international team of researchers looked at 301 placebo-controlled clinical trials for 56 different treatments for low back pain. The team found that most non-surgical and non-interventional treatments did not work. Those that did work provided only small analgesic effects better than a placebo.

Specifically, they found that NSAIDs were the only treatment that worked for acute low back pain, while five treatments for chronic low back pain provided relief: exercise, spinal manipulative therapy (chiropractic), taping, antidepressants, and transient receptor potential vanilloid 1 agonists, which are topical patches like Qutenza (capsaicin).  

As for the treatments that did not work, the researchers found that three treatments for acute low back pain – exercise, glucocorticoid injections, and paracetamol (acetaminophen) – and two treatments for chronic low back pain (antibiotics and anaesthetic drugs) were ineffective. 

They didn’t have enough good quality evidence for the remaining treatments to determine if they worked or not. 

For acute low back pain, 10 non-pharmacological treatments had “low to very low certainty evidence” that they actually worked, including: acupuncture, behavioral health education, extracorporeal shockwave, heat, laser and light therapy, massage, mobilization, osteopathic, spinal manipulative therapy, and transcutaneous electrical nerve stimulation (TENS). 

They also found that 10 pharmacological treatments had inconclusive evidence about their effectiveness for acute low back pain, including: cannabinoids, colchicine, immunoglobulin, muscle relaxants, muscle relaxants + NSAIDs, nucleoside, opioids, ozone injections, pyrazolone derivatives, and topical rubefacients.

For chronic low back pain, over three dozen treatments had inconclusive evidence to support their efficacy, which included everything from bee venom and TENS to dry cupping and muscle relaxants.

The bottom line is that there’s not much evidence to support the use of many treatments that are commonly prescribed and promoted for lower back pain — even the ones recommended in medical guidelines.

“Our review did not find reliable evidence of large effects for any of the included treatments,” researchers concluded. “There are also common treatments for which no placebo-controlled trials have been conducted despite being commonly recommended in clinical practice guidelines.”

The study ends as many often do, with a plea for more high-quality evidence to give patients and doctors real choices and effective options for treating back pain. 

“While we would like to provide more certain recommendations for where to invest and disinvest in treatments, it is not possible at this time,” researchers said.

Experimental Cannabis Extract Has ‘Potential to Replace Opiates’

By Pat Anson

A German biotech company says it is seeking regulatory approval in Europe and the United States for an experimental cannabis extract that could be an alternative to opioid pain medication.

Vertanical recently completed two Phase 3 studies of its new drug – called VER-01 – on over 1,000 patients with chronic low back pain who didn’t get sufficient relief from non-opioid analgesics.

One study compared VER-01 to a placebo, while the second trial compared the drug’s safety and tolerability to patients treated with opioids. The company told The Times it was awaiting publication of the studies’ findings in The Lancet before making them public.

“VER-01 reduces pain without creating dependency or having an abuse potential,” said Clemens Fischer, MD, Vertanical’s CEO. “It has the full potential to replace opiates as it’s more effective. It’s a real alternative for chronic patients — the first one.

“Pain patients around the world are trapped in a vicious cycle of pain, insomnia, limited mobility, and depression. VER-01 has the potential to successfully break this cycle.”

VER-01 is a “full-spectrum” extract derived from cannabis sativa leaves and flowers. Although it contains THC, the main psychoactive substance in cannabis, Fischer says patients enrolled in the studies didn’t become high or intoxicated. About 25 percent did “feel a bit dizzy” for two weeks after they started taking it.

Participants also didn’t get “the munchies” or gain weight, a well-known side effect of cannabis.

“We were looking very carefully, because that’s what we hear from cannabis smokers — that the appetite increases as well their weight. But we haven’t seen any increase in weight,” Fischer told The Times.

Vertanical is seeking regulatory approval of VER-01 in Europe and with the UK’s Medicines and Healthcare Products Regulatory Agency. If granted, VER-01 would be the first cannabis-based medicine approved for chronic pain. It would be sold under the brand name Exilby and be taken orally in drops.

The timeline for approval in Europe may be as soon as this summer, but it’s likely to take longer in the U.S.

“We are seeking regulatory approval in the US and are in talks with the FDA. For approval in the US, a further phase 3 study with US patients in the indication of chronic low back pain will start in Q2 2025,” Merit Renner, Senior Manager of Business Development at Vertanical, told PNN in an email. “This, together with the phase 3 study successfully conducted in Europe, will form the basis for approval in the US.”

Vertanical also plans further studies of VER-01 on patients with osteoarthritis and peripheral neuropathy.

Research into the pain-relieving properties of cannabis has been slow in the U.S., in large part because of marijuana’s status as a Schedule 1 Controlled Substance, the same classification as LSD and heroin. The DEA recently allowed more marijuana to be used for research purposes, but has dragged its feet about reclassifying marijuana as a Schedule 3 substance that could be used for medical purposes. Until marijuana is rescheduled, VER-01 is unlikely to get FDA approval.

Some recent studies have shown that certain cannabinoids found in marijuana -- cannabidiol (CBD), cannabigerol (CBG), and cannabinol (CBN) – block pain signals in the peripheral nervous system, not the brain, and don’t have a psychoactive effect that could lead to abuse.

“These findings open new avenues for the development of cannabinoid-based therapies,” said Mohammad-Reza Ghovanloo, PhD, lead author of a study published in PNAS and a research scientist at Yale School of Medicine. “Our results show that CBG in particular has the strongest potential to provide effective pain relief without the risks associated with traditional treatments.”

The cannabinoids in the Yale study interact with a protein in cell membranes called Nav1.8, which blocks peripheral nerves from transmitting pain signals. Inhibiting Nav1.8 is the same method used by Journavx (suzetrigine), a non-opioid analgesic recently approved by the FDA for relieving moderate to severe acute pain in adults.

The Pain Scale is a Pain, but Doctors Ignore Alternatives

By Crystal Lindell

When I first started having debilitating rib pain more than 10 years ago, doctors would constantly ask me to rate my pain on a scale of 1-10. 

It was the worst pain I had ever experienced, but I didn’t want to sound too dramatic, so I would almost always tell them an 8 or a 9. 

However, I started to notice a troubling pattern: No matter what number I said, the doctors still treated me with the same mostly dismissive attitude. 

So, regardless of whether I said my pain was a 7, a 3, or even an 11, the doctors I was dealing with did not seem to believe me. They seemed to think I was being dramatic no matter what. 

At the time, I blamed myself. Surely I must not be communicating the severity of my pain well, if these doctors are still ignoring me, I thought. 

So I started scrounging around online for alternatives. I assumed that if I just explained myself better, then they would react with the urgency that I felt the situation called for.  

I also thought that perhaps I was picking the wrong number, which was causing doctors to dismiss me as someone who couldn’t accurately assess my own body. 

The first thing I found was a pain scale written out, where each number was explained, like this one from “My Health Alberta.” 

It includes a written description with each number, starting with:

0 = No pain.

1 = Pain is very mild, barely noticeable. Most of the time you don't think about it.

2 = Minor pain. It's annoying. You may have sharp pain now and then.

3 = Noticeable pain. It may distract you, but you can get used to it.

And so on. 

Looking at that chart, I decided that my new rib pain – which was eventually diagnosed as intercostal neuralgia that was caused by Ehlers-Danlos Syndrome – was a: “8 = Very strong pain. It's hard to do anything at all.”

The fact that I would often just lay on the exam table silently crying while I prayed that whatever doctor I was in front of would actually help me, made me feel pretty confident in my assessment of an “8.”. 

It was, indeed, very strong pain that made hard to do anything at all. 

I was also naive enough to believe that if I personally added the descriptor when I gave my number, that it would serve as some sort of magic spell that would finally unlock access to the treatment I needed. 

Alas, that did not work. Doctors just nodded and typed “8” into their little online chart and then moved on through the appointment the same way that they always had: With their trademark unsympathetic arrogance and suggestions about taking more gabapentin.  

After that, I went a step further: I tried to find a pain scale that felt more relevant. Eventually, I discovered the Quality of Life Scale, (QOLS). It’s designed for chronic pain patients to show how their pain is impacting their daily life.  

It's a reverse of the traditional pain scale, in that 0 is the worst pain, while 10 means you're doing pretty well. 

It features descriptions like: 

0: Stay in bed all day. Feel hopeless and helpless about life. 

1: Stay in bed at least half the day. Have no contact with the outside world. 

All the way up to:

10: Go to work/volunteer each day. Normal daily activities each day. Have a social life outside of work. Take an active part in family life. 

At the time, I was about a 4: Do simple chores around the house, minimal activities outside the home two days a week. 

Although those "activities" were just doctor's appointments, I was technically leaving my house every few days.

Looking back, I truly believed that using the QOLS scale with my doctors would be the breakthrough moment for my relationship with them. I remember printing it off and putting it in my healthcare binder full of hope that they would finally understand how bad things were for me. 

Alas, I was mistaken. 

Before I started having chronic pain, I was working a full-time job and a part-time one, and living independently. But my pain had gone untreated for so long that I had cut back on everything possible in my life. I shifted my full-time job to a work-from-home position, quit my part-time job, gave up my apartment, and moved in with family, who lived 2 hours away. 

I still remember thinking that when I told the two doctors I was seeing regularly about how I needed to quit my job and move in with my mom, that they would FINALLY see how severe my pain had been. Afterall, these were the real-life implications of where I was on the QOLS pain scale! 

Wrong again. Instead, both doctors just expressed quiet relief that I was moving out of the area, and thus I’d no longer be their problem! 

Thankfully, when I moved, I did find a new doctor who did take my pain seriously. And although it took some time to get the pain treatment situation under control, it’s been relatively well managed for years now. 

What I have come to realize about the pain scale is that most of the time, it’s not so much an assessment tool as it is a way for patients to feel a false sense of agency over their medical situation.

It’s like a little breadcrumb that doctors give patients to make them feel included in their own healthcare. 

Because in practice, doctors don’t give much weight to whatever number you say your pain is at. Instead, they rely on their own visual and sometimes physical assessment to determine how much pain they think you are in. 

This can be especially problematic for patients from oppressed or marginalized groups, because doctors are less likely to take their pain seriously in general. 

It’s also a huge problem for patients with chronic pain. That’s because when you live with pain every single day, you don’t react to a 10 on the pain scale the same way someone with acute pain would. It’s just not possible to live everyday screaming at the top of your lungs, or performing whatever stereotypical action doctors assume that someone with “real” pain would exhibit. 

For example, one of the things I learned quickly is that I needed to keep myself as calm as possible during a pain flare, because the more stressed and anxious I got, the more it elevated my pain. 

However, a 10 on the pain scale is still just as horrific, even if you’ve been at a 10 for months at a time. And it should elicit the same sense of urgency that would be customary for someone in acute pain saying that their pain was at a 10. 

In fact, I’d go so far as to argue that a 10 for a chronic pain patient can be even more harmful, because if you’re dealing with that level of pain for a long time, it will likely destroy your life. 

Unfortunately, most doctors can’t grasp any of this. So if you show up to an emergency room with an eerie sense of calm while trying to tell them that your pain is a 10/10, they are likely to be very skeptical. 

I wish I could end this column with some sort of solution for patients, but sadly, I don’t think I have one. If your doctor isn’t taking your pain seriously, they probably won’t change their approach just because you show them a different version of a pain scale. 

No, the solution to the frustrating experience of the pain scale will have to come from the other side: from doctors. 

My suggestion is that they start by just believing all patients and then responding accordingly. Unfortunately, under our current healthcare system, I don’t see that happening any time soon.

So all I’ve got for now, is all I’ve ever got: My hope for you that you’re not in too much pain today. 

Chronic Pain Is Chronically Expensive

By Crystal Lindell 

My fiancé and I both have chronic pain. Which means we both spend a lot of money trying to manage it. 

Later today, he will drive an hour and a half each way to see his pain doctor so that they can drug test him in person.  He’s the only doctor in the region who will take new pain patients, so he’s the doctor my fiancé goes to, despite the long drive.

The doctor doesn't take my fiancé’s insurance though, so he will have to pay for the appointment the same way he pays for every monthly appointment with this doctor: with $160 cash. 

And when he gets his medication refill in a few days, that will also have to be paid for with cash at the pharmacy, because his insurance won’t cover prescriptions from doctors who don’t take the insurance. So that’s another $53. 

Aside from the direct costs of that whole ordeal, there’s also the in-direct costs like gas in the car, time away from being able to work on our (very) small online business, and the energy he’ll have to spend dealing with the drive and the stress. 

While he doesn’t have to see this doctor in-person every month, he does have to pay the full price for the appointment every 30 days, along with the prescription. So we have to find a way to basically pay for the equivalent of a car payment every month just so he can have the pain medication he needs to function. 

It’s just one of the ways living with chronic pain gets expensive fast, and also stays expensive. 

There’s the obvious stuff people think of, like the cost of both of us seeing doctors and filling prescriptions. But there’s also the less obvious stuff, like the regular purchases of bulk ibuprofen, Excedrin, and of course antacids for the heartburn caused by the other medications. 

And then there’s the more expensive stuff like the closet full of orthopedic braces, crutches, and walking aids.

There's also the $100/month we spend on kratom powder, which is the only over-the-counter substance that actually helps either of us when our very limited supply of prescription pain meds aren’t enough. And with the current swing in temperatures here in northern Illinois, there are a LOT of days when our limited pain meds aren’t enough. 

We also buy Gatorade every week to take the kratom with, because we’ve found it’s the best and cheapest option to use to get the dirt-like powder down. 

It all adds up so fast, especially with seemingly unlimited inflation. And it ends up being money that we can’t use to improve our lives in other ways, like building savings, having a wedding, or paying off debt. 

Speaking of debt, there’s also the added aspect of all the medical debt I’ve racked up over the last decade, despite having insurance for most of that time. It has essentially destroyed my credit, making it that much harder to secure housing and transportation. 

From the outside, it’s easy to assume that our money troubles must be caused by either our inherent laziness or our inability to budget correctly. But when you have health issues, your money is not the same. It is both harder to get and harder to keep. 

All of these costs are non-negotiable. We can’t just skip his doctor appointment because we have unexpected car problems to pay for. We can’t go without kratom as a trade off if we have unexpected veterinary bills for one of our cats. 

There are a lot of ways that society could be set up differently to help people with chronic pain and chronic illness. Things like universal health care, universal basic income, and expanded public transportation options would go a long way.

I would hope the fact that I’m a human being makes me worthy of social supports like that, but if that’s not enough, there are plenty of selfish reasons for other people to support expanded government programs.

While you may assume that because you don’t need some of these support systems yet, then you never will, you’d be wise to reconsider. Because that’s the thing about chronic illness: If you live long enough, eventually you’ll get sick too. 

And when you do, you’ll find out just how chronically expensive chronic illness really is.

Arachnoiditis Is an Autoimmune Disease

By Dr. Forest Tennant

After several years and numerous studies, we have determined that Adhesive Arachnoiditis (AA) is an autoimmune disease – a condition in which autoantibodies or cellular elements erroneously recognize tissue as virulent or pathologic and attack it, producing inflammation and tissue destruction.

AA only occurs when inflammation forms jointly in the cauda equina and arachnoid membrane of the spine. After the inflammation becomes significant, adhesions form which fuse or “glue” cauda equina nerve roots to the arachnoid membrane. An autoimmune process is the generator and initiator of this inflammation.

The primary generator of the autoimmune process that causes AA is almost always reactivation of the Epstein-Barr virus (EBV) from its normal, dormant, parasitic state. EBV reactivation may occur multiple times over a lifetime.

This same process is now known to be a major causative factor in several cancers and other autoimmune diseases, including multiple sclerosis and systemic lupus erythematosus.

The autoimmune process of EBV has two components: autoantibodies and auto-reactivity. The latter occurs when the virus enters a cell and releases high amounts of self-antigen, which stimulates tissue destruction.

In rare cases, a virus other than EBV may generate autoimmunity and cause AA. Other viruses, especially cytomegalovirus, herpes 6, and covid, may also accelerate or potentiate EBV autoimmunity.

In the past it was generally assumed that epidural injections, spine surgery, contamination of spinal fluid by toxins, or spine trauma were the cause of AA. It is now known that these events may trigger EBV autoimmunity in spinal tissues. Our studies plainly show that AA is preceded and/or accompanied by other autoimmune conditions such as arthritis, migraine, and irritable bowel.

Medical practitioners and persons afflicted with AA must now recognize, diagnose, and treat AA as an autoimmune disease caused by EBV reactivation.

Doctors are more prone to want to treat a disease than they are to treat pain, so classifying AA as an autoimmune disease may improve pain treatment. I'm getting a lot of doctors who are coming on board with this, who see that a patient has a legitimate disease and don't mind prescribing some Vicodin, Tramadol, or Percocet to treat it.

More information about the Epstein-Barr Virus and its relationship to AA and other chronic pain conditions can be found in our book: "The Epstein-Barr Virus: A New Factor in the Care of Chronic Pain."

New Guideline Recommends Against Injections for Chronic Back Pain

By Pat Anson

An international panel of experts has released a new guideline strongly recommending against injections for chronic back pain, saying the procedures provide little or no pain relief and there is little evidence to support their use.

The guideline, published in The BMJ, covers 13 commonly used interventional procedures, including epidural injections, joint injections, intramuscular injections, nerve blocks, and radiofrequency ablation. The injections usually involve steroids, a local anesthetic, or a combination of the two.

The expert panel conducted an analysis of dozens of clinical trials and studies, and found “no high certainty evidence” of pain relief for any of the procedures. There was only low or moderate evidence that injections work better than a placebo or sham procedure.

Injections for chronic axial or radicular spine pain have become increasingly common in recent years, and are often touted as safer alternatives to opioid medication.

However, the injections also come with risks, including infections, prolonged pain and stiffness, accidental punctures of the spinal membrane, and rare but “catastrophic complications” such as paralysis. The risks are magnified because many of the procedures are performed multiple times on the same patient.

“The panel had high certainty that undergoing interventional procedures for chronic spine pain was associated with important burden (such as travel, discomfort, productivity loss), which would be recurring as these interventions are typically repeated on a regular basis, and that some patients would bear substantial out-of-pocket costs,” wrote lead author Jason Busse, DC, a professor of anesthesia at McMaster University in Ontario, Canada.

“The panel concluded that all or almost all informed patients would choose to avoid interventional procedures for axial or radicular chronic spine pain because all low and moderate certainty evidence suggests little to no benefit on pain relief compared with sham procedures, and these procedures are burdensome and may result in adverse events.”

Chronic back pain is the leading cause of disability worldwide. Over 72 million U.S. adults suffer from chronic low back pain, according to a 2022 Harris Poll. About a third of those surveyed rated their pain as severe and nearly half said they experienced chronic back pain for at least five years. The vast majority (80%) rated opioids as the most effective treatment.

Pain Management Needs ‘Major Rethink’

In an editorial also published in The BMJ, Jane Ballantyne, MD, an anesthesiologist and retired professor at the University of Washington, said the new guideline raises questions about whether interventional procedures should even be used to treat chronic back pain. 

“The question this recommendation raises is whether it is reasonable to continue to offer these procedures to people with chronic back pain. Chronic back pain is highly prevalent, a great deal of money is spent on the injections, and a lot of patient hopes and expectations are vested in this type of treatment,” wrote Ballantyne. 

“One might ask how the situation arose whereby we spend so much of our healthcare capital on a treatment for a common condition that compromises the lives of so many people but seemingly does not work.”

For Ballantyne to ask that is more than a little ironic. She is a longtime anti-opioid activist, a former president of Physicians for Responsible Opioid Prescribing (PROP), and was a key advisor to the CDC when it drafted guidelines that strongly recommend against opioid therapy.

With opioids increasingly difficult to obtain, many patients with chronic back pain have no alternative but to have interventional procedures, spinal surgeries, or implanted medical devices such as pain pumps and spinal cord stimulators.

Some doctors and pain clinics welcome the opportunity to bill for those expensive procedures, and refuse to give opioids to patients unless they agree to become “human pin cushions.”

“One might ask how the situation arose whereby we spend so much of our healthcare capital on a treatment for a common condition that compromises the lives of so many people but seemingly does not work.”

— Jane Ballantyne, MD

One might ask Ballantyne what patients with chronic back pain are supposed to do without injections or opioids. Her editorial provides no answers.

“This (new guideline) will not be the last word on spine injections for chronic back pain, but it adds to a growing sense that chronic pain management needs a major rethink,” Ballantyne wrote.

Earlier this month, the American Academy of Neurology released a new evidence review that found epidural steroid injections have limited efficacy, and only modestly reduce chronic back pain for some patients with radiculopathy or spinal stenosis.
