Wear, Tear & Care: The Biomat

By Jennifer Kain Kilgore, Columnist

Some pain relief modalities are unusual to the point that they’re out in the stratosphere. It’s also true that some products only work for some people. Just because a device doesn’t offer visible results the first, second, or even third time doesn’t mean it isn’t working.

That is why I have to keep an open mind and not make snap judgments based on concepts, websites, or promotional material.

Like, for instance, today’s topic: thermotherapy and the Amethyst Richway Biomat.

Amethysts?

Yes, amethysts -- February’s birthstone -- can also be beneficial in thermotherapy.

When speaking specifically about the Biomat, I should warn you that Richway’s website isn’t slick. The idea of amethysts being associated with anything health-related is out of most people’s comfort zone.

But hey, I’ve used the Biomat for upward of five years and fall onto it whenever I have sore muscles, which is constantly. It’s such a fixture in my life that at first I didn’t even think to discuss it. So here we go!

The Biomat. Behold:

This version is the full-body mat covered with a sheet. Underneath my head is the Biomat pillow. Each session can last for five minutes or twelve hours, depending on how much time you have available. The heat can reach temperatures of 158 F° degrees. Read on to find out why that number means absolutely nothing when it comes to treating pain.

The FDA has approved the marketing of the Biomat for a whole host of things: relaxation of muscles, improvement of circulation, temporary relief of muscle pain and/or spasms, and much more. There are specific range settings for certain medical conditions, though it is generally safe.

The science involved came to being when Drs. Erwin Neher and Bert Sakmann discovered how ions flow in and out of cells, which they called the “ion channel theory.” The two scientists revolutionized the field of cell biology and won the Nobel Prize in 1991 for their shared research.

If you’re like me, you have no idea what this means. However, this ion channel theory is put into play by the Biomat’s use of negative ions, which is then complemented by far infrared spectrum therapy (or thermotherapy, like what is found in saunas) and the amethysts embedded in the outer layer of the mat. These stones have been used for thousands of years for everything from fighting the evils of drunkenness to helping with meditation.

In modern times, researchers discovered that amethysts can carry an electrical charge. (Readers, are you still with me? Hang on, we’re almost there!) So, the infrared rays pass through the amethyst layer of the mat and then become “long wavelengths capable of safely penetrating the body as deeply as seven inches.” This heats up your core body temperature, encouraging your body to detoxify.

To put all of this in English: The Biomat creates an environment in which the patient can safely enjoy negative ion therapy and infrared therapy.

What does this mean for the person actually flopped onto the mat? It means a yummy, delicious, low-grade heat. And low-grade does mean low-grade, even if it can reach 158 F° degrees.

One time, my husband wanted to use a heating pad on a strained muscle and cranked it all the way up to eleven: “Honey, I don’t think this is working. I’ve maxed it out and it’s still not warm enough.”

That’s because it doesn’t generate heat the same way a traditional heating pad does. It gets toasty, sure, but you couldn’t cook meat on top of it. At its price point, you certainly wouldn’t want to cook any sort of food on it.

I mean, look at the controls. It’s like the cockpit of an airplane.

For me, the Biomat doesn’t present a dramatic “Before and After” picture. It’s not like Tiny Tim could throw away his crutches after using this product. I can’t think of things I couldn’t do before that, with the Biomat, I can do afterward. Even so, I would never stop using it.

This product is just better than a heating pad. When you hurt all over, you want something that reaches all over. Those of us with chronic pain, we use a plethora of heating devices and creams and patches in order to soothe sore muscles. The Biomat, while extremely expensive, is a full-body restoration and relaxation device. Even the mini mat fits into a chair and covers a lot of real estate.

At the end of a long day, I look forward to sitting on the Biomat. I sleep better when I use it; in the summer, for instance, even a low-grade heat is too much for me, and I go to bed feeling stiffer and more rickety, like a broken marionette. Those are the days I truly notice a difference. Studies have been conducted regarding thermotherapy and resulted in pain decreasing significantly (concurrently with anger and depression). It has even been used to treat cancer.

So does one recline upon the Biomat and come forth as a new person? No, not after one session, two sessions, twelve sessions, or fifty sessions, but you absolutely do feel better. Your muscles are soothed. Your knots unwind, even just a little bit. Your pain is quieted for a time. And that’s enough for me.

Can Alcohol Help Treat Chronic Pain?

By Pat Anson, Editor

Treating chronic pain with a glass of wine or beer may not sound like a good idea, but an intriguing new study in the U.K. found that alcohol consumption is associated with lower levels of disability in pain patients.

Researchers at the University of Aberdeen in Scotland surveyed over 2,200 people with fibromyalgia and other chronic widespread pain conditions about their alcohol consumption. About a quarter of the respondents were teetotalers, the rest drank rarely, moderately or heavily – the latter consuming as much as 21 to 35 “units” of alcohol a week.

A “unit” was defined as 10 ounces of beer, a small glass of wine or a single beverage with hard liquor – meaning the heaviest drinkers averaged three to five drinks a day.

Drinkers overall reported less disability than people who never drank alcohol, but it was the heaviest drinkers who reported the least disability. They were 67% less likely to experience disability than the teetotalers.

“As well as an association between alcohol consumption and lower levels of disability in pain patients, we also found that the population prevalence of chronic pain was lower in drinkers than in non-drinkers. It’s clear that non-drinkers are more likely to have pain, and more likely to be disabled by it if they have it, compared to drinkers,” said Marcus Beasley, study coordinator at the University of Aberdeen.

Does alcohol act as an analgesic and simply dull pain sensations? Or does it treat and help prevent chronic pain? The researchers are cautious about drawing any conclusions.

“This study has demonstrated strong associations between level of alcohol consumption and CWP (chronic widespread pain). However the available evidence does not allow us to conclude that the association is causal. The strength of the associations means that specific studies to examine this potential relationship are warranted,” wrote Professor Gary Macfarlane, lead author of the study published in the journal Arthritis Care & Research.

“The design of this study cannot tell us whether drinking causes people to have less problems with pain, or if people who have pain make the choice not to drink. In any case people that drink are very different on a wide range of health measures than those that do not drink,” said Beasley.

“For primary care practitioners these findings mean that the fact a patient does not drink could be considered a potential marker for having other health problems, including with chronic pain. Otherwise, the advice that practitioners give to patients should remain the same – drink less if possible, and if consuming alcohol then do so within recommended safe limits.”

Previous research has linked moderate alcohol consumption with a lower risk of heart disease, stroke and diabetes. But drinking too much alcohol can lead to a variety of serious health problems.

How much is too much?

According to the Mayo Clinic, moderate alcohol consumption for healthy adults means up to one drink a day for women of all ages and men older than age 65, and up to two drinks a day for men age 65 and younger.

The UK study isn’t the first to find an association between alcohol and a reduced risk of chronic pain. A large study conducted in Sweden, published in the British Medical Journal, found that women who had more than three drinks a week had about half the risk of developing rheumatoid arthritis than non-drinkers.

Another study, published in Arthritis Research & Therapy, found that low and moderate drinkers suffering from fibromyalgia had less pain, less fatigue and missed fewer days of work than non-drinkers.

Wear, Tear & Care: The Quell Pain Relief Device

By Jennifer Kain Kilgore, Columnist

When presented with the Quell pain relief device, people make one of two assumptions about me: 1.) I injured my knee, or 2.) I am a paroled felon wearing a very forgiving Velcro GPS.

As I said in my recent guest column, I have made it my mission to test as many pain relief products and therapies as possible. Some of them might be familiar to you; others will be of the “new and bizarre” variety. Whatever they are, I will be your Friendly Neighborhood Guinea Pig and review them for your convenience. I only draw the line at “Made for TV” products that are out to swindle the desperate consumer.

Pain patients are certainly desperate. We have a constant refrain humming through our bodies that plays a different tune for each person. Doctors are the musicians taught to hear those tunes -- but how can they possibly learn all the music? How can they hear your specific song and have the knowledge necessary to fix it?

The problem is that sometimes they cannot. They are deaf to your pain, just like that one whale who sings higher than every other whale -- none of them can hear her.

Thus far, doctors have been unable to hear the song that thrills along my nerve endings. This leaves me with no choice but to fend for myself. I could take the route at which they have hinted: find some street drugs and wait for the undertow to take me (not that this is the problem the media makes it out to be). Or I could travel a different road and at the same time realize that this life of mine includes pain. If I can’t get rid of it, I can at least muffle it.

As I said recently in my blog -- Wear, Tear, & Care -- I have been trying the Quell pain relief device, which is made in the great state of Massachusetts (i.e., my backyard). I have been using it every day for more than a month. Here are my findings:

• It absolutely works. I have been wearing it for 35 days. I assume there was some psychosomatic effect at first because I was so excited to try the device after months of hype. Once the initial thrill wore off, I was left with the knowledge that, yes, I have reduced my number of Motrin from 16 a day to four, give or take. I am still on Cymbalta and Lyrica for pain control and situational depression, though I can now contemplate reducing the Lyrica entirely. Before, that was not even a possibility.
• Wearing any kind of medical device during the summer is difficult. I can make the Stride of Pride and show if off with a skirt or shorts; otherwise I have to find pants under which the device can comfortably fit. This means that a good portion of my wardrobe (leggings, skinny jeans, etc.) is not compatible with the Quell. This is a minor concern.
• The Quell is $249.00. Replacement electrodes cost $30 and last for two weeks. I have worn mine for longer than that because A.) I can, and B.) I’m cheap. The electrodes break down quickly, but as a whole they are more durable than traditional electrodes and do not irritate my skin. With the EMPI device, the electrodes left blisters on my back.
• The iPhone app is quite lovely. It has a countdown clock so you can see how long the therapy has lasted or how far away it is. I have become adept at the internal calculation of 60 minutes on, 60 minutes off.
• Unlike other TENS devices I have tried, the stimulation is not distracting, so wearing it at the office is fine.

This is all well and good. But how does the Quell work?

According to their research paper presented to the FDA, the Quell works not unlike other devices that latch onto a dense cluster of nerves in the upper calf. Generally it is best for lower-body pain (sciatica and the like), diabetic neuropathy, and fibromyalgia. I myself have fibromyalgia-ish symptoms, since my pain radiates all over my body. However, I apparently do not actually have the inflammation that is fibro’s hallmark. Doctors will only commit to “chronic pain syndrome.” Since the device works for me, I can say confidently that it treats more than those three conditions.

The Quell is twice as strong as conventional TENS units, does not irritate the skin like traditional electrodes, is less conspicuous, has a mobile app, and can be worn at night. (They say it can be worn at night; I personally found the stimulation too distracting.) It activates endogenous opioids in the body (natural opioids, to say it in English), a different system than the one on which prescription opiates work.

It is, simply put, a wearable intensive nerve stimulator that follows the Pain Gate Theory: The impulses generated by the Quell block pain signals from reaching the brain. As it was cleared to be sold over-the-counter, it is currently not covered by insurance.

I know you pain patients out there loathe the numbers system (What is your pain on a scale of 1 to 10?). I also despise it; this is the only one that has come close to working for me. That’s why I have created a new system. Instead of assigning an arbitrary number to my pain, I am going to tell you what I can do now that I couldn’t do before.

1. I can cut down my daily over-the-counter medication.

2. I can walk for longer periods of time (36 days ago I could walk about 10 minutes before starting to limp; now I can make it almost 30 minutes).

3. I can sit for longer periods of time during the work day (prior to the Quell I’d last 10 minutes before having to get up and move around; now I can make it to 30 before movement becomes necessary).

4. I can focus better on immediate tasks.

5. I have more energy during the daytime, which makes me more social. I have been hanging out with friends more. However, I still practice the chronic pain version of sundowning in the evenings (i.e., I crash).

6. I have been able to resume my almost-daily yoga practice. I even did a 55-minute video the other day (which was   Aroga Yoga’s yoga class for those with chronic illness).

7. I have been able to resume my aqua aerobics practice two to three times per week.

8. I wear my emergency back brace less frequently.

9. I have fewer flares.

FINAL DIAGNOSIS: The Quell device has worked brilliantly for me. While it doesn’t get rid of all the pain I feel, it dampens enough of it so that I can more fully live my life. I hope that it can bring others as much relief.

Most Pain Patients Use Alternative Therapy (Video)

By Pat Anson, Editor

A large new study of chronic pain patients found that over half were using chiropractic care or acupuncture for pain relief, but many didn’t discuss their use of alternative therapy with their primary care providers.

Researchers surveyed over 6,000 patients in Oregon and Washington State who were Kaiser Permanente members and had three or more outpatient visits for chronic pain in 18 months.

The study, published in the American Journal of Managed Care, found that 58 percent of the patients had used chiropractic care, acupuncture, or both.

Over a third (35%) of the pain patients who had acupuncture never told their doctor, while 42% who had chiropractic care didn't talk to their providers about it. Almost all of the patients said they would be happy to share this information if their doctor had asked.

"Our study confirms that most of our patients with chronic pain are seeking complementary treatments to supplement the care we provide in the primary care setting," said Charles Elder, MD, lead author of the study and affiliate investigator at the Kaiser Permanente Center for Health Research. "The problem is that too often, doctors don't ask about this treatment, and patients don't volunteer the information.

"We want our patients to get better, so we need to ask them about the alternative and complementary approaches they are using. If we know what's working and what's not working, we can do a better job advising patients, and we may be able to recommend an approach they haven't tried,” said Elder, who is the lead physician for Kaiser Permanente's complementary and alternative medicine program.

The majority of the patients in the study (71 percent) were women, and the mean age was 61. Most suffered from back pain, joint pain, arthritis, neck and muscle pain, or headache.

The study was funded by a grant from the National Center for Complementary and Integrative Health.

A video report on the study that was produced by Kaiser Permanente can be seen here:

One-hundred million Americans suffer from chronic pain every year, and many of them turn to alternative therapies for relief. In fact, a new study shows that more than half of patients with chronic pain enrolled in a managed care setting use chiropractic care or acupuncture.

Is Cinnamon a Safer Pain Reliever?

By Pat Anson, Editor

A new warning from the U.S. Food and Drug Administration about the risk of serious side effects from non-steroidal anti-inflammatory drugs (NSAIDs) may have you thinking about finding safer, more natural pain relievers.

The idea isn’t new by any means – about 2,400 years ago the Greek physician Hippocrates was writing about the use of willow bark to ease aches and pains. Other natural remedies used for centuries to relieve pain and reduce inflammation include St. John’s Wort, ginger, ginseng, turmeric, and cinnamon.

Cinnamon, in fact, was recently found to be nearly as effective as the NSAID ibuprofen in relieving pain from menstrual cramps (dysmenorrhea).

The results of a small double-blind clinical trial, published in the Journal of Clinical and Diagnostic Research, evaluated the effects of cinnamon, ibuprofen and a placebo in 114 Iranian female college students. The women were broken up into groups of three; and given either 420 mg of Cinnamon Zeylanicum, 400 mg of ibuprofen or a starch placebo during the first 72 hours of their menstrual cycle.

Eight hours after treatment, researchers found that pain severity in the cinnamon group was significantly less than those who took a placebo, while pain severity in the ibuprofen group was less than those who took cinnamon.

Although ibuprofen was found to be the more effective pain reliever, the researchers believe cinnamon may be a better treatment for menstrual cramps because it doesn’t have the side effects of ibuprofen.

“The research results suggest that, Cinnamon as compared significantly reduces the severity and duration of pain during menstruation, but this effect is less compared to that of Ibuprofen. Due to the lack of adverse events in this study, Cinnamon can be used as a safe and non-pharmacological treatment for primary dysmenorrheal pain in young girls,” the researchers reported.

Iranian researchers have also found that thyme oil and lavender oil were effective in treating menstruation cramps, according to GreenMedInfo.

Last week, the FDA warned that "everyone may be at risk" from using NSAIDs – and ordered drug makers to strengthen warning labels about the risk of a fatal heart attack or stroke.

The warning applies to Advil, Tylenol, Motrin and other popular pain relievers sold over-the-counter, as well as all prescriptions drugs containing ibuprofen and acetaminophen. Many multi-symptom cold and flu products, such as NyQuil and DayQuil, also contain NSAIDs.

The agency said studies have shown the risk of serious side effects can occur in the first few weeks of using NSAIDs and could increase the longer people use the drugs. The revised warning does not apply to aspirin.

Opioid Implant Raises Safety Questions

(Editor’s Note: Our story about an opioid implant that could someday be used to treat chronic pain struck a nerve with a lot of readers. One of them was Mary Maston, a pain sufferer and  patient advocate, who wrote in expressing concern about the safety and risks associated with implants and other medical devices.)

By Mary Maston, Guest Columnist

Why is everything going to implants? Implants seem to have an initial success rate and I can't argue with the fact that they do work for some, but it seems that class action lawsuits for side effects and internal injuries invariably come about down the line.

Transvaginal mesh was touted as the "next big thing." I had a doctor try to convince me that it would solve all of my female problems. Luckily, I didn't bite. We all know how that ended up.

Bladder slings come to mind too. Some IUD’s have caused issues. People have had major problems with hip and knee replacements. Spinal cord stimulators are being pushed on patients in record numbers, and the bomb is eventually going to drop on those too.

While there are success stories, there are some pretty horrific stories floating around online about implanted devices in general. Some will argue collateral damage: "Just think of the ones they've helped. The many outweigh the few.”

But I can promise you that the ones that have been harmed by these implants see things much differently.

Here's the thing: anything implanted in the body is going to be seen as a foreign object. What does the body tend to do when there's a foreign object inside it? It attacks it, trying to force it out. That's why your eyes water when you get something in them, that's why you vomit when you ingest something that's harmful, and that's why you go to the bathroom -- so the body can rid itself of waste.

When it can’t force the implants out, the body rebels with side effects, infections and pain. The surgeries required to implant these things damage nerves and create scar tissue, which also contribute to pain.

If they're planning on this new implant being simply injected into the arm instead of being surgically implanted, that's going to have to be one heck of a big needle! The size of a match stick? Ouch!!

Then there is the issue of tolerance. Pain medication is not a "one size fits all" fix like the makers of this implant are implying. It comes with a preloaded dose of buprenorphine. How can they guarantee that the dosage they put in it is going to work for the majority of the people it's implanted in? 

What if it stops working in a month or two, or doesn't work at all? Do they have that one taken out and another one put in, or is the old one left in and a new one with a stronger dose implanted?

Will the patient be able to go back to taking oral pain medication? What if it causes side effects in the patient after a few days or weeks that they can't handle, or they end up being allergic to the medicine? How long would they have to live with those issues before it is removed?

Some people metabolize medications faster than others, so saying that it's going to work for a full six months for the implant or an entire month for the injection in everyone isn't practical. What about breakthrough pain? If someone had the implant, but showed up in the ER in pain because of their condition, would they be treated respectfully and in a timely manner, or dismissed because they had the implant and "that should take care of all of your pain."

There needs to be a very specific and compassionate treatment protocol set up for patients before this scenario happens, and all doctors need to be required to follow it.

I can understand and appreciate some of the pros listed in the article. Not having to make trips to the pharmacy, not having to remember to take pills and waiting for them to kick in to feel better. Possibly and hopefully not having to go to the doctor every month and being subjected to random drug screens and pill counts.

Doctors would certainly benefit because they wouldn't be prescribing pain medications nearly as much or maybe not at all. That would definitely get them off the hook with the DEA and I can see how that would make them want to push it onto all of their patients.

I understand that addiction and chronic pain go hand in hand for some people. Not all, but some. But as a chronic pain patient, I don't want to be lumped into the same category as addicts, because I am not an addict, never have been and never will be.

This raises serious questions that I think should be considered before we shout to the heavens how wonderful this new implant is going to be for addicts and legitimate chronic pain patients alike.

I understand there is still a lot of work to be done, and that it's going to take time and testing to answer a lot of these questions. Oral medications certainly have their own set of problems and aren't without risks either. However, history tells us that jumping on a bandwagon isn't necessarily a good thing down the road in a lot of cases.

I'm not saying that the thought of being pain free for an extended amount of time isn't appealing. Honestly, I would probably be more apt to try this than a spinal cord stimulator. But I hope that the manufacturers and the FDA will address the questions I've posed. I guarantee you I'm not the only one that will ask them.

Implant Could Be ‘Game Changer’ in Pain Treatment

By Pat Anson, Editor

Imagine going to your doctor’s office and getting an implant put in your arm that delivers a steady flow of pain medication for six months.

No more pills. No more trips to the pharmacy. No more worries about your pain medication getting lost or stolen.

That’s the scenario a New Jersey drug maker envisions for its Probuphine implant – tiny rods about the size of a matchstick designed to be inserted subcutaneously under the skin of the upper arm.

Probuphine was developed by Braeburn Pharmaceuticals under a license agreement with Titan Pharmaceuticals (OTC: TTNP), which holds the rights to the implant technology. Both companies have applied to the Food and Drug Administration to have Probuphine approved to treat opioid addiction, but Braeburn’s long term goal is to also have the implant approved for chronic pain.

COURTESY TITAN PHARMACEUTICALS

“We are definitely interested in talking to the FDA about the use of Probuphine in pain,” said Behshad Sheldon, President and CEO of Braeburn.

The active ingredient in Probuphine is buprenorphine, a weaker opioid that’s long been used as an addiction treatment drug sold under the brand name Suboxone. Buprenorphine is also used to treat chronic pain and comes in various forms – pills, patches and film strips – but none as long-acting as an implant.

The advantages of an implant are many. The dosage is controlled and there’s hardly any risk of abuse, diversion, or accidental overdose. You also never have to remember to take a pill.

“We believe a buprenorphine implant could be a really great clinical tool to treat pain,” Sheldon told Pain News Network. “There’s just a peace of mind aspect for the patients. The medicine’s on board and they don’t have to worry about it.”

“I personally would want a Lipitor implant, because I can’t manage to take it three days in a row,” she joked.

Probuphine’s path to the marketplace hasn’t been a smooth one. Braeburn and Titan were stunned in 2013 when the FDA denied approval of the implant and asked for a new clinical study of Probuphine’s effectiveness in treating opioid addiction.

Braeburn recently reported the results of a six month, double-blind clinical trial of Probuphine on 177 patients, which found that the implant was more effective than buprenorphine tablets in treating addiction. The company said the implant insertion and removal were "generally well tolerated," although nearly one in four patients had a "mild" adverse event at the implant site.

“The data from this trial are encouraging and underscore the benefit of longer term medical treatments for patients with opioid addiction. I am confident that the implant, if approved by FDA, will be at least as effective as a sublingual formulation and have the added benefits of reducing problems related to compliance, misuse and abuse,"  said Richard Rosenthal, MD, Professor of Psychiatry and Medical Director of Addiction Psychiatry at the Icahn School of Medicine at Mount Sinai.

Braeburn and Titan plan to resubmit a New Drug Application (NDA) for Probuphine to the FDA in the second half of this year.

Long Term Injection for Pain

Braeburn has formed another partnership with Camurus, a Swedish drug company, to develop an injectable buprenorphine drug to treat addiction and chronic pain -- a single injection that lasts as long as a month. Camurus has already completed successful Phase I and II studies on the drug and both companies hope to start a Phase III trial later this year -- with the goal of seeking regulatory approval in 2016.

“There have been many conversations with expert clinicians and they’ve told us that they think buprenorphine in general, in a non or less abuse-able form of buprenorphine, in either an implant or an injection could really be game changing,” said Sheldon. “It is part of our plan to move into pain because pain and opioid addiction are so interconnected and we think there are ways, by treating patients with a less abuse-able formulation, you could actually help alleviate the addiction problem.”

Sheldon admits a lot more work needs to be done before a buprenorphine implant or injection is available to treat chronic pain.

“We haven’t studied it yet in pain and we haven’t had any conversations yet with the FDA. So there’s a lot more to do to get to that point,” she said.

Another formulation of buprenorphine to treat pain may be coming to the market relatively soon. Endo International (NASDAQ: ENDP) and BioDelivery Sciences (NASDAQ: BDSI) have submitted a new drug application for a buprenorphine film patch to the FDA. The companies are hoping for FDA approval by October of this year.

Although the patch contains much smaller doses than buprenorphine tablets or patches already on the market, the companies say the film is very effective in treating pain because the drug is absorbed through the inside lining of the cheek and enters the blood stream faster.

Critics Question Oxygen Therapy for Fibromyalgia

By Pat Anson, Editor

Some experts are challenging the findings of a new clinical study that found that hyperbaric oxygen therapy (HBOT) could be used to treat -- and possibly even cure -- fibromyalgia.

Israeli researchers gave HBOT therapy to dozens of women suffering from fibromyalgia and found there was a significant improvement in their pain and other symptoms. The women were put in pressurized air chambers and breathed pure oxygen for 90 minutes, five times a week for two months.

Researchers say brain scans of the women before and after HBOT proved their theory that additional oxygen alters brain pathology and "repairs" parts of the brain overly sensitized by chronic pain. 

"Brain pathology? This is speculation being presented as established knowledge," said John Quintner, MD, an Australian rheumatologist who maintains that fibromyalgia is not a disease, but a "symptom cluster" that could have many different causes.

tHE INTERIOR OF A HYPERBARIC CHAMBER. COURTESY OF Sagol Center for Hyperbaric Medicine and Research

Fibromyalgia is a poorly understood disorder that is characterized by deep tissue pain, headaches, fatigue, depression and insomnia. The cause is unknown.

"This clinical trial is using a methodology that is predicated upon fibromyalgia being a distinct medical condition," said Quintner, telling Pain News Network that the study proved little, but was "good news for those who manufacture portable HBOT units." 

Researchers at the Sagol Center for Hyperbaric Medicine and Research at the Assaf Harofeh Medical Center and Tel Aviv University were studying the use of HBOT on stroke and concussion patients when they realized that oxygen therapy might also change the neural activity of patients with fibromyalgia.

"Patients who had fibromyalgia in addition to their post-concussion symptoms had complete resolution of the symptoms," said Shai Efrati, MD,  lead author of the study that is published online in PLoS ONE. 

Efrati said some patients will require follow-up sessions of HBOT and some won't need to.

"We have learned, for example, that when fibromyalgia is triggered by traumatic brain injury, we can expect complete resolution without any need for further treatment. However, when the trigger is attributed to other causes, such as fever-related diseases, patients will probably need periodic maintenance therapy."

HBOT puts more oxygen into the bloodstream, which delivers it to the brain. Efrati's earlier studies found that HBOT induces neuroplasticity, which leads to repair of chronically impaired brain functions. Most of the women who participated in the new study had fibromyalgia that the researchers believe was triggered by brain trauma.

DR. SHAI EFRATI

"Symptoms in about 70 percent of the women who took part have to do with the interpretation of pain in their brains," said Eshel Ben-Jacob, a study co-author who is an adjunct professor of biosciences at Rice University. "They're the ones who showed the most improvement with hyperbaric oxygen treatment. We found significant changes in their brain activity.

"Most people have never heard of fibromyalgia. And many who have, including some medical doctors, don't admit that this is a real disorder. I learned from my MD friends that this is not the only case in which disorders that target mainly women raise skepticism in the medical community as to whether they're real or not."

HBOT Claims Called "Crazy" 

One of those skeptics is Fred Wolfe, MD, a prominent fibromyalgia researcher who says the Israeli study lacks proper controls used in most clinical studies -- such as patients being "blinded" to whether they are receiving treatment or a placebo.  

"The fibromyalgia study world is filed with positive studies based on unacceptable controls," said Wolfe. "While I don't know enough about this treatment to be sure, I would tend to think the symptomatic improvement could be based on control and blinding problems. It is possible that the demonstrated effect on the brain of oxygen is separate from the effect of symptoms." 

Wolfe is particularly troubled by a recommendation at the end of the study that fibromyalgia patients should undergo HBOT therapy now, "rather than wait until future studies are completed.”  

"I could only characterize (that) as crazy. Crazy because of the money it would cost and crazy because it posits fibromyalgia as brain disease. FM is not a disease and there is a difference between mechanism and causes. One needs some replication before jumping in," said Wolfe in an email to Pain News Network. 

Many fibromyalgia patients are ready to jump in, based on the comments from readers to our first report about the Israeli study.

"Where do you find studies like this to volunteer? I would so do this," wrote one fibromyalgia sufferer.

"I would so try this. I often feel like I'm not getting enough oxygen," said another.

"Sign me up, please," a woman wrote.

"Is this available in Tucson or Phoenix, Arizona?" asked another woman.

Many fibromyalgia sufferers are desperate for any kind of treatment that would provide relief, much less a cure. In the Israeli study, several patients either drastically reduced or eliminated their use of pain medications.

"The results are of significant importance since, unlike the current treatments offered for fibromyalgia patients, HBOT is not aiming for just symptomatic improvement," said Efrati. "HBOT is aiming for the actual cause -- the brain pathology responsible for the syndrome. It means that brain repair, including even neuronal regeneration, is possible even for chronic, long-lasting pain syndromes, and we can and should aim for that in any future treatment development."

John Quintner is not convinced.

"I have thought long and hard about this issue and have come to the conclusion that we have been dealing with a 'symptom cluster' rather than with a syndrome," he said. "According to my understanding, fibromyalgia is best explained as an  'idiom of human distress' and, as such, is outside the purview of the biomedical model." 

Can Oxygen Therapy Treat Fibromyalgia?

By Pat Anson, Editor

Hyperbaric oxygen therapy – also known as HBOT – has been used for decades to treat infections, severe burns, carbon monoxide poisoning, even scuba divers recovering from decompression sickness.

Patients undergoing HBOT are put in a pressurized room or tube. The higher air pressure allows lungs to gather more oxygen than they would normally – helping the body to heal faster.

Promising new research out of Israel suggests that HBOT can also be used to treat fibromyalgia patients by causing neuroplasticity – a “re-wiring” of the brain that can change neural activity in areas overly sensitized by chronic pain. The study has been published in the journal PLoS ONE.

“This study provides evidence that HBOT can improve quality of life and well-being of many FMS (fibromyalgia) patients. It shows for the first time that HBOT can induce neuroplasticity and significantly rectify brain activity in pain related areas of FMS patients,” wrote lead author Shai Afrati, MD, of the Institute of Hyperbaric Medicine, Assaf Harofeh Medical Center.

Fibromyalgia is a poorly understood disorder that is characterized by deep tissue pain, headaches, fatigue, depression and insomnia. The cause is unknown and there is no cure.

Afrati, who has also studied oxygen therapy on stroke and concussion victims, enrolled 60 female fibromyalgia patients in his latest study. For five days each week they were given 90 minutes of HBOT with oxygen enriched air.

“It is plausible that increasing oxygen concentration by HBOT can change the brain metabolism and glial function to rectify the FMS-associated brain abnormal activity. It has already been demonstrated that exposure to hyperbaric oxygen induces significant anti-inflammatory effect in different conditions and pathologies,” said Afrati.

After two months, brain imaging showed the women had significant changes in neural activity, and they reported less pain and fewer tender points. Several said that they had either reduced or stopped taking pain medication.

However, not everyone could handle being placed in a pressurized air chamber. Five women dropped out of the study, complaining of dizziness, claustrophobia and an inability to adjust to the air pressure.

But Afrati is encouraged by the results.  

“Follow-up studies are needed in order to investigate the durability of the HBOT effects on FMS. It might be that some patients will need more HBOT sessions,” he wrote. “Since there is currently no solution for FMS patients, and since HBOT is obviously leading to significant improvement, it seems reasonable to let FMS patients benefit from HBOT, if possible, now rather than wait until future studies are completed.”

Vegan Diet Reduces Neuropathy Pain

By Pat Anson, Editor

A vegetarian diet coupled with a daily vitamin B12 supplement significantly reduced pain and improved the quality of life of people with diabetic neuropathy, according to the findings of a small study published in Nutrition & Diabetes. Participants also lost an average of 14 pounds.

Nearly 26 million people in the United States have diabetes and about half have some form of neuropathy, according to the American Diabetes Association.  Diabetic peripheral neuropathy causes nerves to send out abnormal signals. Patients feel burning, tingling or prickling sensations in their toes, feet, legs, hands and arms.

Many drugs used to treat neuropathic pain, such as Neurontin and Lyrica, often don’t work or have unpleasant side effects.

Researchers at California State University, East Bay, and the George Washington University School of Medicine put 17 adults on a low-fat vegan diet that focused on vegetables, fruits, grains and legumes. Typical meals included oatmeal with raisins, pasta with marinara sauce, vegetable stir-fry with rice, and lentil stew.

Participants also took a daily vitamin B12 supplement, as did a control group that did not alter its diet.

After 20 weeks, patients on the vegan diet not only had less neuropathic pain, they had lower blood pressure and cholesterol levels and had lost weight.

"A dietary intervention reduces the pain associated with diabetic neuropathy, apparently by improving insulin resistance" said Neal Barnard, MD, president of the Physicians Committee for Responsible Medicine at CSU East Bay.

Researchers also noted there was significant improvement in pain and other symptoms in the control group.  The magnitude of the improvement suggests that the B12 supplement, intended to serve as a placebo, may have had real effects in both groups.

One in three children born in the U.S. in 2000 will develop diabetes at some point in his or her life. The average lifetime cost to treat type 2 diabetes is $85,200, half of which is spent on diabetes complications.

"The dietary intervention is easy to prescribe and easy to follow," says Cameron Wells, a registered dietician and acting director of nutrition education for the Physicians Committee. "Steel-cut oats, leafy greens, and lentils are widely available at most food markets and fit well into most budgets."

Better Sleep Means Less Pain

By Pat Anson, Editor

Getting a good night’s sleep plays a key role in determining how bad your pain levels are doing the day, according to a large new study by researchers in Norway.

The study included more than 10,400 adults from an ongoing Norwegian health study. Each participant underwent a standard test of pain sensitivity -- the cold pressor test -- in which they were asked to keep their hand submerged in a cold water bath for 106 seconds.

Only 32% of participants were able to keep their hand in cold water throughout the experiment. Those who suffered from insomnia were more likely to take their hand out early: 42% did so, compared with 31% of those without insomnia.

Pain sensitivity also increased depending on the frequency of insomnia. Those who had trouble sleeping at least once a week had a 52% lower pain tolerance, while those who reported insomnia once a month had a 24% lower tolerance for pain.

"While there is clearly a strong relationship between pain and sleep, such that insomnia increases both the likelihood and severity of clinical pain. It is not clear exactly why this is the case," wrote lead author Børge Sivertsen, PhD, of the Norwegian Institute of Public Health.

The study, which is published in the journal PAIN,  is the first to link insomnia and impaired sleep to reduced pain tolerance in a large, general population sample. The results suggest that psychological factors may contribute to the relationship between sleep problems and pain, but they do not fully explain it.

“We conclude that impaired sleep significantly increases the risk for reduced pain tolerance. As comorbid sleep problems and pain have been linked to elevated disability, the need to improve sleep among chronic pain patients, and vice versa, should be an important agenda for future research,” the study said.

A previous study in Norway found that women who have trouble sleeping are at greater risk of developing fibromyalgia – although it’s not clear if there’s a cause and effect relationship between the two symptoms.

Another study, recently published in PLoS One, found that insomnia – not surprisingly – made chronic pain patients less likely to exercise. Researchers followed 119 chronic pain patients, most of whom suffered low back pain, and found that quality of sleep was the best predictor of physical activity the next day – not mood or pain intensity.

Weird Mushroom Could Lead to New Painkillers

By Pat Anson, Editor

A creepy looking parasitic mushroom that lives on caterpillars could help British researchers develop a new class of painkillers to treat osteoarthritis and other chronic pain conditions.

Scientists at the University of Nottingham are exploring the painkilling potential of cordycepin, a compound found in cordyceps mushrooms, which have been used in traditional Chinese medicine for thousands of years.

The mushroom acts as a parasite in the larvae of ghost moths – growing inside the caterpillar until it eventually kills it. The stalk-like mushroom then grows out of the caterpillar’s mummified body.

Food pellets containing the compound were given to rats and mice to see if cordycepin could relieve pain from a joint injury. The results, according to researchers, were startling.

"When we first started investigating this compound it was frankly a bit of a long-shot and there was much skepticism from the scientific community," said Dr. Cornelia de Moor. "But we were stunned by the response from the pilot study, which showed that it was as effective as conventional painkillers in rats.

A CORDYCEPS MUSHROOM (LEFT) EMERGES FROM A DEAD CATERPILLAR

"This study is the first step in a potential drug development for a new class of drugs for osteoarthritis, although there are a number of hurdles we have to go through - necessarily so - before it gets nearer patients. To the best of our knowledge, cordycepin has never been tested as a lead compound for osteoarthritis pain."

Native Tibetan healers have used cordyceps mushrooms as a tonic to treat a wide variety of conditions. They claim it improves energy, appetite, stamina, libido, endurance, and sleeping.

Researchers believe cordycepin blocks the inflammatory process that cause pain in osteoarthritis, but does so in a way that is completely different than painkillers like corticosteroids and non-steroidal-anti-inflammatory drugs (NSAIDs) such as ibuprofen.  Still unclear is whether cordycepin acts on the knee joint or on the nerves that send pain signals from the knee to the spinal cord.

Until clinical trials can be held to test the safety and effectiveness of cordycepin – which could take years – de Moor warns against people experimenting with herbal products containing the cordyceps mushroom.

"The lack of quality control means that cordyceps preparations for sale in Europe rarely contain much cordycepin, and may contain other harmful compounds," said de Moor, who is also investigating cordycepin as a possible treatment for cancer.

"Dr de Moor's research is certainly novel, and we believe may hold promise as a future source of pain relief for people with osteoarthritis. There is currently a massive gap in available, effective, side-effect-free painkillers for the millions of people with arthritis who have to live with their pain every day, so new approaches are very much-needed,"  said Dr. Stephen Simpson, director of research at Arthritis Research UK, which is helping to fund de Moor’s research.

Osteoarthritis is a progressive joint disorder caused by painful inflammation of soft tissue, which leads to thinning of cartilage and joint damage in the knees, hips, fingers and spine. The World Health Organization estimates that about 10% of men and 18% of women over age 60 have osteoarthritis.

Physical Therapy Lowers Healthcare Cost of Back Pain

By Pat Anson, Editor

Early physical therapy for low back pain significantly lowers healthcare costs by reducing the use of expensive treatments such as spinal surgery, injections, imaging and painkillers, according to a large new study published in the journal BMC Health Services Research.

About a quarter of Americans report an incidence of low back pain (LBP) within the previous three months and it is one of the most common reasons to visit a physician. Most LBP episodes resolve within 2 to 4 weeks, but about 25% of patients will experience recurring back pain for a year or more. 

Researchers analyzed health care records for over 122,000 patients in the U.S. Military Health System who went to a primary care physician for an initial episode of low back pain and received physical therapy within 90 days. 

Over 17,000 patients in the study received early physical therapy within 14 days – and it was this group that made significantly less use of advanced imaging, spinal injections, spine surgery and opioids than patients who started physical therapy later. 

Health care costs on average were 60% lower (about $1,200) over a two year period for patients who had early physical therapy compared to those who delayed therapy.

"Physical therapy as the starting point of care in your low back pain episode can have significant positive implications," said physical therapy researcher John Childs, PhD. "Receiving physical therapy treatment that adheres to practice guidelines even furthers than benefit."

Medical guidelines recommended for low back pain are to avoid opioids and advanced imaging as a first-line of treatment. However, recent research shows those guidelines are often ignored.

A large new study by pharmacy benefit manager Prime Therapeutics found that about one in five opioid prescriptions were written to treat low back pain.

"Low back pain was the most common diagnosis among all members taking an opioid, even though medical guidelines suggest the risks are likely greater than the benefits for these individuals," said Catherine Starner, PharmD, lead health researcher for Prime Therapeutics.

Another study of older adults with low back pain found that spending thousands of dollars on advanced imaging such as CT scans or MRI’s within six weeks of visiting a primary care doctor was often a waste of money.  

“Early imaging was not associated with better one-year outcomes. The value of early diagnostic imaging in older adults for back pain without radiculopathy is uncertain,” said Jeffrey G. Jarvik, MD, a professor of radiology in the University of Washington School of Public Health, who studies the cost effectiveness of treatments for patients with low back pain.

Combined direct and indirect costs for low back pain in the U.S. are estimated to be between $85 billion and $238 billion a year.

"Given the enormous burden of excessive and unnecessary treatment for patients with low back pain, cost savings from physical therapy at the beginning of care has important implications for single-payer health care systems," said Paul Rockar, President of the American Physical Therapy Association.

Physical Therapy vs. Surgery for Spinal Stenosis

By Pat Anson, Editor

Physical therapy works just as well as surgery in relieving pain and other symptoms of lumbar spinal stenosis in older patients, according to researchers at the University of Pittsburgh.

Their two year-year study, published in the Annals of Internal Medicine, is believed to be the first that compares outcomes between surgery and physical therapy (PT) for spinal stenosis, a condition caused by narrowing of the spinal canal that causes pain, numbness and weakness in the lower back.  Decompression surgery to relieve pressure on spinal nerves has become a fast-growing intervention in today's older population.

"Probably the biggest point to put across to physicians, patients and practitioners is: Patients don't exhaust all of their non-surgical options before they consent to surgery. And physical therapy is one of their non-surgical options," said principal investigator Anthony Delitto, PhD, chair of the Department of Physical Therapy, University of Pittsburgh School of Health and Rehabilitation Sciences.

Delitto, a physical therapist, was puzzled why some patients responded well to physical therapy  and others to surgery.

In his study, 169 patients aged 50 and older with spinal stenosis agreed to be randomly assigned to two groups: Those who would have decompression surgery and those who would have two standardized physical therapy sessions each week for six weeks.

In his study, 169 patients aged 50 and older with spinal stenosis agreed to be randomly assigned to two groups: Those who would have decompression surgery and those who would have two standardized physical therapy sessions each week for six weeks.

After both groups were re-examined at intervals of six months, one year and two years, the patient outcomes appeared to be about equal. There were no detectable differences between the groups in how their pain abated and the degree to which function was restored in their backs, buttocks and legs.

"The idea we had was to really test the two approaches head to head," said Delitto. "Both groups improved, and they improved to the same degree. Now, embedded in that, there are patients who did well in surgery, and patients who failed in surgery. There are patients who did well in PT, and there are patients who failed with PT. But when we looked across the board at all of those groups, their success and failure rates were about the same."

The research project also revealed issues surrounding physical therapy and the cost of co-pay – which apparently discourage some patients from continuing their treatment.

"One of the big things that we know held patients back from PT were co-payments," Dr. Delitto added. "Patients were on Medicare, and a lot of them were on fixed incomes. Some of those co-payments had to come out of pocket at $25, $30, $35 per visit. That adds up, and some of the patients just couldn't afford it."

Most patients didn't finish the PT regimen allowed under Medicare and one-third of the patients failed to complete even half of the regimen. About one in six didn't show for a single treatment, though they had agreed to consider physical therapy.

Counseling and Behavioral Therapy Help Vets in Chronic Pain

By Pat Anson, Editor

An innovative two-step program that combines analgesics with deep breathing, relaxation techniques and counseling significantly reduced pain levels in U.S. military veterans who suffer from chronic pain, according to a new study at a VA Medical Center.

Researchers at the Roudebush VA Medical Center in Indianapolis, the Regenstrief Institute and the Indiana University School of Medicine studied 241 veterans who returned from deployments in Iraq and Afghanistan. Findings from the ESCAPE trial -- short for Evaluation of Stepped Care for Chronic Pain – are being published in JAMA Internal Medicine.

It is a critical health issue among veterans, many of whom had multiple, often lengthy deployments. Many have significant long-term pain. We know that medications alone are only modestly successful in helping them; current pain treatments haven't made much of a dent,” said Matthew Blair, MD, the study’s lead investigator and an associate professor of medicine at Indiana University.

A recent study found that nearly half of the American soldiers deployed to Iraq and Afghanistan return home to the U.S. in chronic pain, and about one in seven were using opioid pain relievers. Although pain is a common condition, researchers say no intervention studies had been conducted on the best ways to treat chronic pain in these veterans.

“The absence of studies is concerning because chronic pain may prove even more disabling in veterans of recent conflicts than in veterans of previous eras owing to the high combat intensity,” said Bair, who served for eight years as a U.S. Army physician.

The veterans in the ESCAPE study suffered from moderate to severe chronic pain in the back, knee, neck or shoulder for at least three months. Veterans with substance or abuse problems were excluded from the study, as were those with suicidal thoughts, active psychosis or schizophrenia.

In the first phase of ESCAPE, patients were given 12 weeks of pain medication, ranging from acetaminophen to opioids. Because analgesics may not relieve pain sufficiently when used alone, the veterans were educated about self-management strategies such as goal setting, problem solving, deep breathing and relaxation techniques. Patients were also encouraged to minimize bed rest, return to normal activities, and perform stretching and strengthening exercises.

Step two involved 12 weeks of cognitive behavioral therapy that included psychological counseling for both pain and depression. Nurse care managers consulted with veterans over the telephone, helping them counter negative thoughts – such as helping them understand that while they may not be able to perform the same physical activities they enjoyed before deployment, a substitute activity like swimming might be achievable and decrease their pain.

Those who received the two-step ESCAPE program saw improvement in their function and a decrease in pain severity and pain interference -- how pain interferes with their mood, physical activity, work, relationships, sleep and enjoyment of life.

“The decrease in pain severity and 30 percent improvement in pain-related disability we achieved in the ESCAPE study are clinically significant, and we found that improvement lasted for at least nine months," said Blair.

Researchers say the ESCAPE program could be duplicated to treat chronic pain at other VA medical centers and other large health care systems outside the VA. However, implementing the program in smaller community settings or in private settings may be challenging.

"This is an important, methodologically rigorous study that underscores the value of psychobehavioral treatment in chronic pain,” said Beth Darnall, PhD, a pain psychologist and author of Less Pain, Fewer Pills. “Cognitive-behavioral therapy and the use of relaxation strategies work exceedingly well within the context of a comprehensive pain management program, and when the techniques are used regularly.”

Darnall recommends the same techniques used in the VA study in her own private practice.

“It’s important for people to know that the results from psychobehavioral skills build over time.  In other words, use them daily and your results will unfold and strengthen over the course of weeks and months,” she wrote in an email to Pain News Network.
