Virtual Reality Has Long-Term Benefits for Patients with Back Pain

By Pat Anson, PNN Editor

A novel treatment that combines virtual reality with cognitive behavioral therapy significantly reduced pain levels and other symptoms in patients with chronic back or neck pain, according to results of a new study presented at the annual meeting of the Congress of Neurological Surgeons.

Unlike other therapies using virtual reality (VR) – which temporarily distract people from their pain – patients in this study had long term reductions in their pain, anxiety and depression. This suggests that combining VR with cognitive behavioral therapy (CBT) induces neuroplasticity, a “rewiring” of the brain and nervous system that reduces the impact of physical and emotional trauma.    

“What we found is it actually creates new neural pathways to form, what's called neuroplastic reprogramming or neuroplastic change, and that actually creates a more resilient patient,” said co-author Gerry Stanley, MD, Chief Medical Officer of Harvard MedTech, a medical device company that offers VR therapy.

“The patient who may be thinking about their pain 22 hours a day, and their pain (level) has always been eight or nine, now thinks about their pain one or two hours a day and their pain (level) is a three or four, because the brain is no longer fixating on it. So it allows for, I don't want to say permanent distraction, it’s really neuroplastic reprogramming.”

Stanley and his colleagues enrolled 145 patients with non-operative degenerative neck or back pain in Harvard MedTech’s Vx Therapy program, which included daily virtual reality sessions for 14 weeks and weekly telephone calls with a therapist trained in CBT.  

Unlike other VR therapies, which encourage physical activity, participants sat stationary in a chair while watching and listening to prerecorded programs with a headset and earphones. The VR programs come in four categories that emphasize education, meditation, distraction or entertainment, depending on the patient’s needs and goals.

After 14 weeks, results showed that Vx Therapy reduced pain and anxiety during sessions by an average of 33% and 46%, respectively. The duration of pain relief also increased over time, from 2.5 hours in the first weeks of treatment to 4.5 hours in the final weeks.

The study has not been peer-reviewed or published yet, but Stanley says the findings mirror what his company has learned after treating about 4,000 patients. The benefits of Vx Therapy continue long after the treatment ends, with many patients still reporting improvement after two years.  

“They're often reporting the same level of resiliency. I think a lot of it is they start getting into better sleep patterns,” he told PNN.  “And they really get good at meditation. Most people fail in meditation because of distractions. But when they're doing it in the virtual reality, they get very good at it. So they really develop some nice, I'm going to say muscle memory, even though I know it's cognitive. But they do develop a little bit of muscle memory around the meditation.”

Because Vx Therapy is done remotely, it’s available to any patient regardless of location, as long as they have a prescription. Some worker compensation insurers cover the treatment.   

Previous studies have also suggested that virtual reality therapy has long-term benefits for people with chronic back pain. A 2022 study showed that people with moderate lower back pain reported improvements in pain, function, mood and sleep six months after treatment ended.  

Virtual Reality Therapy Reduces Drug Use During Surgery

By Madora Pennington, PNN Columnist

Imagine going in for minor surgery, one where you don’t need to be totally unconscious, and being given a virtual reality headset for pain and anxiety relief instead of the usual dose of anesthesia.

The virtual reality (VR) device would distract you during surgery by immersing you in a nature scene, like a forest, mountain top or nighttime sky. And a guide meditation would reassure you with, “Surgery is going great! Try to stay still!”

Would this even work?

A small study led by researchers at the University of Colorado sought to find out by looking at 34 patients receiving hand surgery that could be done without general anesthesia. While virtual reality has been widely studied as a treatment for acute and chronic pain, researchers are just beginning to explore whether it can be used during surgery.

“In the field of anesthesia, we are constantly focused on improving patient safety and care quality,” said lead author Adeel Faruki, MD, an anesthesiologist at the University of Colorado Hospital. “There are many studies currently underway assessing if VR can be used for orthopedic joint surgeries.”

Faruki and his colleagues divided the patients into two groups. Half received the usual care and served as a control group, while the other half wore VR headsets and noise-cancelling headphones during surgery to promote relaxation and calmness. Both groups received local anesthesia and the sedative propofol, either upon patient request or at the discretion of an anesthesiologist.

Researchers found that patients in the VR group received significantly less propofol than those in the control group. Only four of the 17 patients in the VR group received any propofol during their surgery, while every patient in the control group received the sedative.

PLOS ONE

Not surprisingly, the VR patients tended to need more supplemental local anesthesia. Propofol can amplify the effectiveness of pain medication, so patients on propofol generally require less numbing and pain relief.

Patients in both groups reported their pain was well-controlled and they felt relaxed during surgery. There were no significant differences in their pain scores or surgery outcomes. In short, the VR group did just as well with the pleasant distraction of the device as those receiving more sedating medication.

There are advantages to using less propofol. The drug is commonly used as sedative during surgery, but poses risks because it tends to depress breathing, which is dangerous. “Acute propofol intoxication" was cited as the cause of pop star Michael Jackson’s overdose death in 2009.

Propofol is also hard on the brain and may cause lower cognition after surgery.  Being less drugged, patients who received VR were discharged from the postoperative recovery room an average of 22 minutes earlier than fully medicated patients. Getting patients released early frees hospital staff and resources for other patients and needs.

Some limitations the authors of the study acknowledge are that patients signing up for VR might be more likely to do well with less anesthesia if they volunteered for it. Neither the patients nor the healthcare providers were “blinded” in this study, meaning everyone knew which patients were getting VR and which ones weren’t. This scenario opens the possibility that providers participating in the study might inadvertently influence the results by giving the VR patients less propofol.

The bottom line for this study, which is being published in PLOS ONE, is that patients can have just as comfortable a surgery with less sedation when VR is used. The study does not prove that VR is better, just that it does as well as sedative medication.

Virtual Reality Shows Long Term Benefits for Chronic Low Back Pain

By Pat Anson, PNN Editor

Critics of virtual reality therapy often say it’s a poor treatment for chronic pain because it only distracts patients from their pain and that the effects are temporary, at best.

But new research suggests that the benefits of virtual reality (VR) can last six months after treatment has stopped – at least for patients with chronic low back pain.

The study, published in the Journal of Medical Internet Research, followed 188 people with chronic low back pain who had an average pain intensity score of 5 on a zero to 10 point scale.

Half the participants were given an EaseVRx headset to watch 3-D programs daily for 8 weeks, immersing themselves in a “virtual” environment where they can swim with dolphins, play games or enjoy beautiful scenery. The goal is help patients learn how to manage pain through cognitive behavioral therapy.  

The other patients also used the EaseVRx headset, but only watched routine nature scenes as a placebo or sham VR treatment.  

JOURNAL OF MEDICAL INTERNET RESEARCH

Patients were followed for six months after treatment was stopped. Participants in both groups reported improvement in their pain and other symptoms six months after treatment, but the improvements were more significant in those who received VR therapy. Pain intensity was 31% lower for patients in the VR group, compared to 16% in the sham group. Physical function, mood, sleep and pain-related interference in activity were also better in those who received VR therapy. No adverse side effects were reported in either group.

“We have been pleasantly pleased and surprised that patients are maintaining clinically meaningful changes in pain intensity and interference 6 months after returning the device. It appears people are actually acquiring skills in a relatively short period that they continue to retain/apply months after treatment,” said Josh Sackman, co-founder and president of AppliedVR, which makes the EaseVRx headset.

AppliedVR is planning more research to see how patients respond long-term to VR treatment. A brain imaging study is being conducted to measure brain activity before, during and after treatment. Patients are also being recruited for a large clinical trial to see how VR therapy impacts pharmacy and medical claims.  

“In order to drive real acceptance, we are committed to extensive research to address any skepticism people may have,” Sackman told PNN.

The EaseVRx headset was given a Breakthrough Device Designation by the FDA in 2020 for fibromyalgia and low back pain. Last year the agency authorized the marketing of the headset for chronic low back pain in adults, the first medical device of its kind to receive that designation.

EaseVRx headsets are currently being used for pain management in over 200 hospitals and healthcare systems. A full commercial launch for home-based use is not expected until next year.

FDA Approves First Virtual Reality Device for Chronic Low Back Pain

By Pat Anson, PNN Editor

The U.S. Food and Drug Administration has authorized the marketing of the first home-based virtual reality (VR) device for the treatment of chronic lower back pain in adults.

The EaseVRx headset uses guided VR programs to help patients relax, meditate and distract themselves from their pain, using the principles of cognitive behavioral therapy (CBT). The device is made by AppliedVR, a Los Angeles-based company that is developing therapeutic VR programs to help treat pain and other conditions.

"Millions of adults in the United States are living with chronic lower back pain that can affect multiple aspects of their daily life," Christopher Loftus, MD, acting director of the FDA’s Office of Neurological and Physical Medicine Devices, said in a statement. “Today's authorization offers a treatment option for pain reduction that does not include opioid pain medications when used alongside other treatment methods for chronic lower back pain."

Chronic lower back pain is defined as moderate to severe pain in the lower back lasting longer than three months. It is one of the most common chronic pain conditions and a leading cause of disability.

The FDA’s marketing approval is based a clinical study of 179 participants with chronic lower back pain. Half were given an EaseVRx headset to watch immersive 3-D programs daily for 8 weeks. The other half also used the headset, but only watched routine nature scenes as a sham treatment.

APPLIEDVR IMAGE

At the end of treatment, 66% of those who watched VR programs reported at least a 30% reduction in pain, compared to 41% of participants in the sham control group.

Nearly half of those in the EaseVRx group reported at least a 50% reduction in lower back pain.

No serious adverse events were reported during the study. About 20% of participants reported discomfort with the headset and nearly 10% reported motion sickness and nausea.

EaseVRx was given a Breakthrough Device Designation by the FDA in 2020 for treating fibromyalgia and chronic lower back pain. The designation speeds up the development and review of new medical devices.

Marketing approval of EaseVRx – known as a "De Novo pre-market review" – creates a new regulatory classification for VR devices. It clears the way for similar devices with the same intended use to obtain marketing authorization – a significant development for the fledgling virtual reality industry.

"We worked tirelessly over the past few years to build an unmatched body of clinical evidence that demonstrates the power of VR for the treatment of pain, and couldn't be more thrilled to achieve this important milestone," said Josh Sackman, AppliedVR’s co-founder and president. "But, our mission does not stop with this one approval. We're committed to continuing research that validates our efficacy and cost-effectiveness for treating chronic pain and other indications."

EaseVRx will only be available by prescription. Its software programs immerse users in a “virtual” environment where they can swim with dolphins, play games or enjoy beautiful scenery.  The content also incorporates biopsychosocial pain education, diaphragmatic breathing, mindfulness, and relaxation exercises.

AppliedVR headsets are already being used for pain management in over 200 hospitals and healthcare systems. A company spokesman told PNN that EaseVRx will be available on a limited basis through select providers toward the middle of 2022, with a full commercial launch expected in 2023. AppliedVR's is currently building a distribution network and working with insurers -- Medicare, Medicaid and commercial -- to establish reimbursement levels. No pricing plans have been announced for its VR headset or programs.

Home-Based Virtual Reality Reduces Chronic Low Back Pain

By Pat Anson, PNN Editor

A new clinical study has found that home-based virtual reality (VR) therapy can significantly reduce pain levels in people suffering from chronic lower back pain. Patients who watched VR programs also reported better mood, reduced stress and that pain interfered less with their sleep.

The study, published in the Journal of Medical Internet Research, is the first controlled trial to compare home-based VR therapy to a “sham” or placebo treatment for chronic pain. The research was funded by AppliedVR, a Los Angeles-based company that is developing therapeutic VR content to help treat pain and other conditions.

Eighty-nine people used the company’s EaseVRx headset daily for eight weeks, immersing themselves in relaxing and meditative VR programs designed to make their pain seem less important, similar to cognitive behavioral therapy. A control group received the sham treatment, watching routine nature scenes with the headset. All participants had chronic low back pain for at least six months.   

By the end of the study, 87 percent of people in the VR group reported less pain intensity, with nearly two-thirds experiencing at least a 30% reduction in pain compared to the control group. There were also significant improvements in sleep, mood and stress in the VR group.

Importantly, the improvements in pain and other symptoms were cumulative over time – meaning the relief was long-lasting and not just when people were watching VR programs.

“If you look at the results graph, you’re able to see the trajectory of pain and pain intensity very reliably declining over the course of the eight weeks. It’s a really strong time trend. It’s not just a random effect,” explained Beth Darnall, PhD, AppliedVR’s chief science advisor.

You can see the graph below. Over the course of 56 days, average pain intensity fell by 43% in patients using the EaseVRx headset, compared to 23% in the control or sham group.

JOURNAL OF MEDICAL INTERNET RESEARCH

Most of the research to date on VR therapy has focused on treating acute pain in hospitalized patients. AppliedVR is trying to demonstrate that virtual reality can also be used to treat chronic pain at home. A small study released last summer showed that home-based VR therapy reduced pain in people with fibromyalgia and chronic low back pain.

Darnall was hesitant to say if there were any pain conditions that VR therapy might not useful for.

“At the end of the day, pain is pain,” said Darnall, who is a pain psychologist at Stanford University. “This basic approach, in which we’re equipping people with self-regulatory skills, is going to be beneficial and broadly applicable for every pain condition.

“We have multiple studies in progress that are testing this device on different populations. It’s really going to be an exciting year, because there’s going to be an explosion of research that’s really going to inform our understanding of how this may help people across different disease conditions.”   

AppliedVR’s headset received breakthrough device designation from the Food and Drug Administration last year. The company hopes to get clearance from the FDA later this year to begin selling the devices. Due to a recent decision by Medicare to start covering breakthrough medical devices, the company is hopeful that private insurers will also start paying for VR therapy. 

FDA Designates First Virtual Reality Device for Chronic Pain

By Pat Anson, PNN Editor

AppliedVR, a Los Angeles-based virtual reality company, has announced that its EaseVRx headset has received Breakthrough Device Designation from the Food and Drug Administration for treating fibromyalgia and chronic intractable low back pain.

EaseVRx is the first virtual reality (VR) device to get a Breakthrough Designation from the FDA for treating a chronic pain condition. The designation speeds up the development and review of new medical devices that treat life-threatening or irreversibly debilitating diseases or conditions. It could also speed up insurance coverage of VR therapy for chronic pain.

“AppliedVR is the most evidence-backed VR platform on the market, and today’s FDA designation demonstrates that health experts across the spectrum recognize the therapeutic potential of VR as a viable treatment for pain,” Matthew Stoudt, CEO and co-founder of AppliedVR, said in a statement.

“Now, with the COVID-19 pandemic severely disrupting Americans’ ability to get in-person care safely, we’re looking forward to getting EaseVRx into the hands of people suffering from pain. Providers believe in it, patients want it, and payers are coming around to it.” 

AppliedVR funded a recent clinical trial that showed VR therapy can be self-administered at home to treat chronic pain. Patients living with fibromyalgia or chronic lower back pain were given VR headsets and instructed to watch at least one virtual reality program daily for 21 days.

The programs immerse users in a “virtual” environment where they can swim with dolphins, play games or enjoy beautiful scenery. The goal is to help patients learn how to manage their pain and other symptoms by distracting them and making their pain seem less important

At the end of the study, 84 percent of the patients reported they were satisfied with VR therapy. Their pain intensity was reduced an average of 30 percent. Physical activity, mood, sleep and stress levels also improved.

“Virtual reality is a promising skills-based behavioral medicine that has been shown to have high patient engagement and satisfaction,” said Beth Darnall, PhD, AppliedVR’s chief science advisor. “However, chronic pain patients to date have had very limited access to it, so we’re excited to continue working with the FDA to develop our platform and get it into the market faster.”

PNN columnist Madora Pennington, who lives with chronic pain from Ehlers-Danlos Syndrome, recently reviewed one of AppliedVR’s headsets. She said watching VR programs helped calm and relax her.

“The benefits of VR therapy continued for me after the sessions ended. When pain or panic about pain began to set in, I found it drifts away rather than latching onto me like it used to,” Madora wrote. “After a couple weeks of VR, during a visit to physical therapist, I noticed I was no longer afraid of her touching my neck and back, and actually enjoyed it.”

AppliedVR’s technology is being used in hundreds of hospitals, but is not expected to be available for home use until next year. The company is working with Geisinger Health and Cleveland Clinic on two studies to see if VR therapy can be used as an opioid-sparing tool for acute and chronic pain.

VR for Phantom Limb Pain

Virtual reality technology received another boost this week when the Department of Defense awarded Chicago-based Coapt a $2.3 million grant to develop virtual reality therapies for phantom limb pain. Wounded veterans and amputees who have lost arms or legs often suffer from nerve pain and other sensations from their missing limbs.

"Phantom limb pain is a serious and persistent challenge for many upper and lower-limb amputees, and new, technology-based therapies have incredible promise," Blair Lock, co-founder and CEO of Coapt, said in a statement. "Preliminary work has shown that VR-based, actuated therapy can manage pain more effectively and have lasting effects. This grant will allow us to further study this therapy and bring to market a solution for those suffering from phantom limb pain in a way that also happens to be engaging."

Coapt has previously developed a VR-based therapy to help upper-limb amputees improve control of their prostheses. The technology also shows promise as a treatment for phantom limb pain. Coapt will use the grant money to further study the effectiveness of VR therapy and create a commercially viable product for both civilians and veterans with upper and lower-limb amputations.

Finding Pain Relief in a Virtual World

By Madora Pennington, PNN Columnist

I am sitting on a deserted beach in Tasmania, listening to the gently lapping waves. All my worries fade in just 3 minutes.

While on my couch, I am touring the famous sites of London. Have I been on vacation? I feel as if I have.

I am by a creek in Bavaria. Water gently crashes against the rocks. Leaves fall to the ground. In four minutes, I am in state of joy.

Underwater with a school of dolphins, twisting my head to get the best views as they swim above me and all around, I forget anything that bothers me, physical or mental.

How can I be in so many places? I am using a virtual reality program designed to relieve chronic pain. I love it. I look forward to doing it every day.

Later, when I am out and about, a sound I heard during my VR sessions, perhaps the swaying of a tree, makes my body relax without effort.

The AppliedVR headset I am using looks like a blacked-out snorkeling mask. It came with a warning not to expose it to direct sunlight, and to take great care not to scratch the lenses. The company loaned me the device to try at no cost and with no stipulations for this review.

Virtual reality (VR) had its start as entertainment in video gaming. Headsets have speakers or earphones, and are usually connected to a joystick or hand controller. When the user moves their head, tracking software shifts the images, providing an immersive experience into a full 360-degree view of a 3D world.

Besides gaming, VR has a growing number of practical uses. VR technology is used to teach dangerous jobs like piloting or to give doctors simulated practice at surgery. The U.S. military uses VR to train soldiers to fight and build mental resilience for battle. Ford employees use VR to inspect and look for problems in virtual automobiles before they are even manufactured. Architects and engineers use it to evaluate and find problems in their design work.

In a medical setting, VR therapy was first used in caring for patients who suffered burn wounds, which can be so painful that even opioids can be insufficient. A study found that VR, when coupled with pain medication, provided burn patients with significant relief.

More Than Just Distraction

How does VR make such a difference in pain?

“The most acceptable theory is the Gate theory of attention. It postulates that VR reduces the perception of pain by absorbing and diverting attention away from pain,” says Dr. Medhat Mikhael, a pain management specialist.

But there’s more to it. Dr. Brennan Spiegel, director of Cedars-Sinai's Health Service Research, completed a VR study on 120 hospitalized patients in 2019, which showed that VR significantly reduces pain. It was most effective for severe pain.

“Virtual reality is a mind-body treatment that is based in real science. It does more than just distract the mind from pain, but also helps to block pain signals from reaching the brain, offering a drug-free supplement to traditional pain management," Spiegel said.

Short-term, acute pain is a different beast than chronic pain. Only a few studies have been done using VR to treat chronic pain, which can overwhelm the nervous system, making the body even more sensitive to and aware of pain. This cycle can become so entrenched it can cause the body to interpret benign stimuli, such as the light brush of fabric against skin, as painful.

Early studies on VR for chronic pain are promising. In a study published in 2016, chronic pain patients had an average 60% reduction in pain from VR treatment. A third of the participants experienced total pain relief while doing VR sessions. They had a wide variety of conditions, such as spine pain, hip pain, myalgia, connective tissue disease, interstitial cystitis, chest pain, shoulder pain, abdominal pain and neuropathy. 

Another study recently found that VR reduces pain and improves mood and sleep in people living with fibromyalgia or chronic lower back pain.  

Pain Drifts Away

I’ve had a lifetime of chronic pain from the collagen disease, Ehlers-Danlos Syndrome. My body is very weak and flimsy. Having chronic pain and disability sometimes makes me feel resentful and betrayed by my own body.

In one VR session, I stare into the heavens. I am shown a projection of a human body and nervous system. A kind, encouraging woman explains simply and compassionately the phenomenon of pain. I hate my body less in two minutes.

Ordinarily, I would never play a video game. I don’t like cartoons. Meditating makes me anxious. I find it difficult to even lose myself watching a movie. I would not have thought I would respond well to virtual reality. But from the first brief session, I did.

I learned how to calm and balance my nervous system in an animated forest. Gently encouraged to breathe in time with a giant whimsical tree, the ground and surrounding plants change, becoming ever more colorful each time I exhale. The loving woman tells me I have changed myself and the outside world. I have to agree.

Some sessions are games that teach me to redirect my attention away from pain. In a cartoon winter wonderland, I shoot snowballs at happy teddy bears, who giggle when I hit them. I have made the teddy bears and myself happy.

In others programs, I swim with jellyfish. Or sunbathe on a beach in Australia. Or sit by a stream in the snowfall. You can watch a sample of these programs below.

The benefits of VR therapy continued for me after the sessions ended. When pain or panic about pain began to set in, I found it drifts away rather than latching onto me like it used to.

After a couple weeks of VR, during a visit to physical therapist, I noticed I was no longer afraid of her touching my neck and back, and actually enjoyed it.

VR reminds me of times in my life when I was fully engaged in the moment and overwhelmed by wonder or beauty. As a child swimming in the ocean, once I was surrounded by dolphins. They clicked and called to each other. I immediately forgot how cold I was and how my wet-suit was cutting off the circulation in my hands.

VR took me back to other transcendent moments of my life, like playing in an orchestra, surrounded by instruments producing layers of organized sound. Standing in front of Van Gogh’s Bedroom. A ride at Disneyland. Falling in love.

My only criticism of VR is the weight of the headset. The device is heavy and could be difficult for someone with neck or head pain to tolerate.

AppliedVR’s technology is being used in hundreds of hospitals, but it is not yet available for home use. The company hopes for a broader launch in 2021, but getting insurance coverage will be key.

"We know that living with and managing chronic pain can be a debilitating and costly challenge that is only exacerbated by the COVID crisis.  As such, we are focused on achieving our vision of delivering safe and effective VR therapeutics into the home where the need for non-opioid chronic pain treatment options is greatest,” says AppliedVR CEO Matthew Stoudt.

“We are now focused on partnering with payers to demonstrate how our chronic pain VR therapeutic improves health outcomes, reduces costs and empowers patients to lead their best lives.  This is the key to making VR a reimbursable standard of care for pain management."

In addition to pain, VR therapy is also being used to relax people going through dental procedures, chemotherapy, physical rehabilitation, phobias, anxiety and post-traumatic stress disorder (PTSD).

You cannot talk your brain out of perceiving pain, but with VR it finds other, better things to do than just focus on pain. Cognitive behavioral therapy and self-soothing techniques do that too, but VR disengaged my brain from the pain perception cycle at a much deeper level, just as pain once hijacked my thoughts and attention.

Virtual Reality Therapy Can Reduce Chronic Pain at Home

By Pat Anson, PNN Editor

Therapeutic virtual reality (VR) can reduce chronic pain, improve mood and help people sleep, according to a small study of 74 patients living with fibromyalgia or chronic lower back pain.

The research, published online in JMIR-FR, is one of the first to look at the effectiveness of VR therapy when self-administered at home by chronic pain patients. It was funded by AppliedVR , a Los Angeles based company that is developing therapeutic VR content to help treat pain, depression, anxiety and other conditions.

“People with chronic pain often have limited access to comprehensive pain care that includes skills-based behavioral medicine. We tested whether VR that was self-administered at home would be an effective therapy for chronic pain,” said Beth Darnall, PhD, a pain psychologist who is AppliedVR’s chief scientific advisor.

“We found high engagement and satisfaction, combined with clinically significant reductions in pain and low levels of adverse effects, support the feasibility and acceptability for at-home, skills-based VR for chronic pain.”

Participants in the study were given VR headsets and instructed to have at least one session daily for 21 days. Half of the patients listened to audio-only programming, while the other half watched “virtual” programs in which they could swim with dolphins, play games or immerse themselves in beautiful scenery.

The programs are designed to help patients learn how to manage their pain and other symptoms by using cognitive behavioral therapy (CBT) to distract them and make their pain seem less important.

A sample of what they saw can be seen in this video:  

At the end of the study, 84 percent of the patients reported they were satisfied with VR therapy, which worked significantly better than the audio-only format in reducing five key pain indicators:

• Pain intensity reduced an average of 30%

• Physical activity improved 37%

• Mood improved 50%

• Sleep improved 40%

• Stress reduced 49%

Previous VR studies have had similar findings, but have largely focused on patients in hospitals and clinical settings. 

“This study is a fundamental step for advancing a clinically proven, noninvasive and safe digital therapeutic like VR for chronic pain, and demonstrates our platform is both viable and efficacious,” said Josh Sackman, co-founder and president of AppliedVR.

“Living with and managing chronic pain daily can be a debilitating and costly challenge, and many patients suffering from it can feel hopeless and desperate for any relief. So, as we engage in and accelerate more in-depth clinical research, we want them to know that we’re committed to making VR a reimbursable standard of care for pain.”

AppliedVR products are being used in hundreds of hospitals, but are currently only available to healthcare providers. The company recently partnered with University of California at San Francisco to study how VR therapy can improve patient care for underserved populations.

AppliedVR is also conducting two clinical trials to see if VR therapy can reduce the use of opioid medication for acute and chronic pain. The National Institute on Drug Abuse recently awarded nearly $3 million in grants to fund the trials.

The company is currently recruiting patients with chronic lower back pain for an 8-week trial of VR therapy. Headsets and other material will be mailed at no cost to participants at their homes. No in-person visits are required.  

Icy Virtual Reality Freezes Out Pain

By Pat Anson, PNN Editor

Everyone knows that an ice pack or cold compress can help sooth aching joints and sore muscles. Cold temperatures slow blood circulation, reducing both pain and inflammation.

Researchers at Imperial College London took that basic first aid measure a step further by using virtual reality (VR) to immerse people in scenes of an icy Arctic landscape. And just like real ice, the VR video reduced pain perception and sensitivity.

Findings from the small study, published in the journal Pain Reports, add to growing evidence that VR technology can not only distract people from their pain, but may also activate the body’s pain-fighting response.

“One of the key features of chronic pain is you get increased sensitivity to painful stimuli. This means patients’ nerves are constantly ‘firing’ and telling their brain they are in a heightened state of pain,” first author Sam Hughes, PhD, said in a press release.

"Our work suggests that VR may be interfering with processes in the brain, brainstem and spinal cord, which are known to be key parts of our inbuilt pain-fighting systems and are instrumental in regulating the spread of increased sensitivity to pain.

In the study, 15 healthy volunteers were given a topical cream on the skin of their legs containing capsaicin – the spicy chemical in chili peppers that makes your mouth burn. The capsaicin sensitized the skin, making it more sensitive to pain from a small electric shock.

Participants were then asked to rate their pain on a scale of 0-100 (from ‘no sensation’ to ‘worst pain imaginable’) while looking at a still image of an Arctic scene on a computer monitor or watching this National Geographic video of Arctic exploration through a VR headset.

Researchers found that pain from the capsaicin cream was reduced following the VR immersion. The volunteers’ skin was also less sensitive to the electric shocks.  The same effect was not seen in people who only looked at still images of the polar environment.

Hughes and his colleagues plan further studies of VR to see what kind of dosing regimen works best for pain – such as 30 minutes of VR, four times a day – and if the pain relieving effects would be cumulative or remain only temporary.

“The aim of this study was to show VR has the ability to change the pathological processing associated with chronic pain,” says Hughes. “Using this approach does seem to reduce the overall intensity of the ongoing pain as well as the response we get on the skin. We think there could be changes in the body’s pain relief system’s which can affect how pain sensitivity is processed in the spinal cord.

“There are still many things to figure out, but one exciting aspect of our study is that the VR design we used is completely passive – meaning patients don’t need to use their arms. Potentially, it could mean that patients who are bed-bound or can't move their limbs, but with chronic pain, could still benefit from this approach.”

Previous studies have found that VR can make small improvements in the pain of hospitalized patients recovering from surgery or suffering from neurological, orthopedic, gastrointestinal or cancer pain.

Study: Virtual Reality Can Relieve Severe Chronic Pain

By Pat Anson, PNN Editor

Therapeutic virtual reality (VR) may finally be on the verge of going mainstream. For the first time, research has shown that VR can help relieve a variety of pain conditions and is most effective for severe chronic pain.

 "I believe that one day soon VR will be part of every doctor's tool kit for pain management," says Brennan Spiegel, MD, director of Health Service Research at Cedars-Sinai Medical Center in Los Angeles.

Spiegel is lead author of a new study published in PLOS ONE, which looked at the effectiveness of VR in 120 hospitalized adult patients suffering from neurological, orthopedic, gastrointestinal or cancer pain. All of the patients were being treated with opioid medication and had a pain score of at least three on a 1 to 10 pain scale.

“There’s been decades of research testing VR in highly controlled environments — university laboratories, the psychology department and so on,” Brennan told MobiHealthNews. “This study is really letting VR free and seeing what happens. What I mean by that is it’s a pragmatic study where we didn’t want to control every single element of the study, but literally just see [what would happen] if we were to give it to a broad range of people in the hospital with pain; how would it do compared to a control condition already available in the hospital?”

Half of the patients were given VR goggles with a variety of relaxing and meditative experiences to choose from. They were advised to use the headsets three times a day for 10 minutes — and as needed for breakthrough pain – for three days.

The other participants were instructed to tune their hospital room TVs to a health and wellness channel that offered programs on guided-relaxation, yoga and meditation.

Several times a day, nurses asked all the patients to rate their pain on the pain scale.

The study found that on-demand use of VR resulted in a small but statistically significant improvement in pain scores compared to the TV group, with patients in the VR group averaging 1.7 points lower on the pain scale. VR patients with the most severe baseline pain of 7 or more reduced their pain scores three points lower than the TV group.

"This is our largest and most ambitious VR study to date," Spiegel said. "Our results support previous research that VR can meaningfully reduce pain using a nonaddictive, drug-free treatment for people experience a range of different pain conditions."

In the previous study, patients who watched a 15-minute nature video had a 13% drop in their pain scores, while patients who played an animated game had a 24% decline.

Spiegel says the current study showed that VR can do more than just distract the mind from pain, but may even block pain signals from reaching the brain by overwhelming the brain with visual and audio stimulation.  

Several patients found VR so helpful in managing their pain that they now use it regularly at home. One of them is 70-year old Joseph Norris, a retired Air Force lieutenant colonel, who suffers from chronic pain in his spine, back and hips. Norris started using VR six months ago, and today uses his VR headset once a week to help relax and distract. 

"VR is a tool I use to successfully divert attention away from my pain, and it helps me reinforce my breathing pattern," he said.

There remains a great deal of skepticism about VR, particularly among older patients. Spiegel and his colleagues evaluated nearly 600 patients for the study, but many chose not to participate.

“Patients expressed varying degrees of skepticism, fear, sense of vulnerability, concern regarding psychological consequences, or simply not wanting to be bothered by using the equipment. We believe it is important for the digital health community to recognize that despite the great promise of health technology, clinical realities can undermine expectations,” he wrote.    

Spiegel and his research team are currently involved in a study following patients using VR in their homes for 60 days.

48 Alternative Therapies to Help Lower Pain Levels

By Barby Ingle, Columnist

A year ago, I began this series of columns on alternative therapies for chronic pain management. There are so many different treatments, we presented many of them by letter – the 4 A’s, the 4 C’s, the 4 E’s, etc. This is my final column in the 12-part series.

In all, we covered 48 different treatment options. But we only scratched the surface. There are literally hundreds of alternative pain therapies and I've tried many of them myself. Many didn’t help me or provided only minimal relief. But I know of others who received great benefits from them.

This final month I am spotlighting trigger point injections, virtual reality, yoga and the yucca plant.

Trigger Point Injections

Trigger point injections can be beneficial in treating myofascial pain syndromes. That is when a patient has chronic musculoskeletal pain in specific parts of a muscle where a knot has formed due to inflammation. This is known as the “trigger point.” Steroids or analgesics (or both) are injected into the trigger point area to get the knot to release and the muscle to relax.

I have had trigger point injections done on my wrist and shoulder at various times. Although it was helpful long-term for my wrist injury, which occurred prior to my developing reflex sympathetic dystrophy, it was not as helpful with managing the RSD symptoms in my shoulder.

I could usually feel the muscle knots under my skin, but that was not always the case. I would also get a twitching response, which my doctor first thought was a sign of low calcium.  But after ruling that out, he realized that it was tight muscle fibers and inflammation.

There are risks with any type of injection. The injection or solution can cause damage to the skin and small nerve fibers, or cause infections and bleeding. If you think that trigger point injections could help, talk with your doctor first to find out if this would be a good option for you.

Virtual Reality

Virtual reality (VR) has been used in different forms of pain management since 1996. It operates under the theory that pain perception can be reduced by refocusing the patient’s attention away from their pain. Typically, that means wearing a headset or goggles that provide a 360-degree view while watching a realistic video or animated game.

AppliedVR in Los Angeles is developing a variety of virtual reality content to help treat pain, depression and anxiety. To give you an idea how it works, watch this promotional video by the company:

VR was first used to alleviate severe pain in patients treated at a burn center in Seattle, Washington. Since then, it has shown to be effective in treating acute pain in hospitals or when patients undergo lengthy testing procedures and need a distraction. I am hearing more and more from providers that VR can help lower the need for medication. 

VR is a fun activity that my husband and I have both tried. We quickly realized that it had therapeutic benefits and helped me to relax and keep my mind focused during long MRI’s and infusions. Like most therapies, the benefits of VR are usually short term. But VR is a promising field that is likely to improve as technology and personalized experiences are brought together in practice. 

Yoga 

Yoga is a mind-body exercise that uses controlled breathing, meditation and movements to stretch and strengthen your body. There are several types of yoga and people have been using yoga moves and thinking for thousands of years. The emphasis for all of them is on treating the mind and body equally.

Yoga can be used for pain relief for many types of chronic conditions, but patients must be cognizant of not pushing themselves into a flare by doing too much at one time. 

One study found that patients with chronic low back pain who took a weekly yoga class increased their mobility more than standard care like physical therapy. Other studies have shown that yoga is comparable to exercise therapy in relieving symptoms from arthritis, fibromyalgia and migraine. 

I have been using yoga in modified positions to strengthen myself. I don’t push myself too hard, because when I did I found myself in a pain flare. But when I go slow and easy, I find that it helps me build strength. For example, I will do the moves in a chair instead of on the floor and skip certain positions that may aggravate my pain. 

Practicing yoga has also helped with my mood, positive thinking and overall well-being. A typical yoga session lasts 45-90 minutes; mine are shorter, about 15-20 minutes at a time. Many people will go to a yoga class, but I do it at home using routines that I modified. Each session usually begins with deep breathing exercises that help me relax and lower stress levels. Then I use a series of yoga positions that are either seated, standing or laying down. Some positions are done quickly and others are held for a few minutes. If it starts to get too much for me, I stop or take a break.

At the end of the yoga session, I go back to breathing and mediation exercises to cool down. Be sure to modify your yoga to fit your needs. Doing some movement and breathing is better than nothing, even if it’s only a few minutes each day.  

Yucca

The Yucca is a plant with more than 40 species that typically grows in desert regions. It is used to make medicines for many conditions, including migraines, headaches, gastrointestinal disorders, osteoarthritis, high blood pressure, diabetes, vascular constriction, and more. 

Yucca medications are applied directly to the skin, made into extracts, or used in carbonated beverages. Some Yucca compounds have even been used in the manufacture of new medications. 

I first heard about the use of Yucca derivatives to treat pain while on a tour of the Desert Botanical Gardens in Phoenix, Arizona. That was where I found out that the Yucca can be used to treat sores, bleeding, sprains and joint pain. My husband is almost bald, and they suggested some people even use it for baldness. 

Researchers have found several Yucca compounds that are similar to anti-inflammatory medications.  Some of the chemicals in Yucca can also help reduce blood pressure or control cholesterol levels. For me, it helps reduce osteoarthritis symptoms by lowering the aching pain, swelling and stiffness I deal with. 

The Yucca plant is native to the southwest United States, where I currently live, as well as Mexico. Around here it is common for people to use the bark and root of the Yucca as a dietary supplement to promote joint health. There are even Yucca products on the market for treating pain in horses, dogs and other animals.

Be Open Minded

My alphabet series on alternative pain management is meant to spark ideas and discussion about treatments that you may not have known about before.  Before you try any of them, I encourage and remind you to talk it over first with medical professionals who are familiar with your past and present care. It is important to also remain open minded about your options and only do what you are comfortable with. 

There is no cure yet for chronic pain. So the more proactive we are in managing the symptoms -- even if we don’t get complete relief -- the better off we’ll be. Being positive, hopeful and creative in finding new ways to manage our conditions can help get our pain levels down.  

Want to see the rest my series on alternative treatments?  Here’s where to find them:

• The 4 A’s: acupressure, acupuncture, aromatherapy and art therapy.  
• The 4 C’s: Calmare, Chinese medicine, chiropractic, and craniosacral therapy. 
• The 4 E’s: energy therapy, electromagnetic therapy, equine therapy, and exercise. 
• The 4 F’s: faith healing, Feldenkrais Method, food, and functional medicine. 
• The 4 H’s: hypnotherapy, hyperbaric therapy, holistic living and herbal therapy.
• 4 Infusions: Ketamine, lidocaine, immunogoblins and stem cells.
• The 4 M’s: Mindfulness, magnets, massage and music.
• The 4 N’s: Nerve blocks, nitric oxide, neurotransmitter regulation and nabilone.
• The 4 O’s: oral orthotics, orthomolecular medicine, osteopathy and occupational therapy.
• The 4 P’s: Physical therapy, pain medications, prolotherapy and psychology. 
• 2 R's, a Q and an S: Quell, radiofrequency ablation, reflexology, sonopuncture

As I have stressed in all 12 articles, each of us is different, even if we are living with the same diseases. Your task is to find creative, effective ways to get the pain conditions you live with under control. I look forward to reading what worked and didn’t work for you.

Virtual Reality Relieves Pain in Hospitalized Patients

By Pat Anson, Editor

Virtual reality therapy significantly reduced both acute and chronic pain in hospitalized patients, according to a new study that adds to a growing body of evidence that virtual reality (VR) can give temporary relief to pain patients. The study is published online in the journal JMIR Mental Health.

Researchers at Cedars-Sinai Medical Center in Los Angeles enrolled 100 patients in the study who had an average pain score of 5.4 on a pain scale of zero to 10.

They suffered from a wide variety of conditions, including gastrointestinal, cardiac, neurological and post-surgical pain.

Fifty patients watched a 15-minute nature video on a computer screen that included mountain scenes and running streams, accompanied by calming music.

The other 50 patients wore virtual reality goggles to watch a 15-minute animated game called Pain RelieVR, which was specifically designed to treat patients who are bed bound or have limited mobility.

The game takes place in a fantasy world where users shoot imaginary balls at a wide range of moving objects by maneuvering their heads toward the targets. The game also uses motivational music, positively reinforcing sounds and direct messages to patients.

The patients who watched the nature video had a 13 percent drop in their pain scores, while patients who watched the virtual reality game had a 24 percent decline in their pain levels. The VR group had no change in their blood pressure or heart rate.

“We found that use of a 15-minute VR intervention in a diverse group of hospitalized patients resulted in statistically significant and clinically relevant improvements in pain versus a control distraction video without triggering adverse events or altering vital signs,” wrote lead author Brennan Spiegel, MD, director of Cedars-Sinai’s Health Service Research.

“These results indicate that VR may be an effective adjunctive therapy to complement traditional pain management protocols in hospitalized patients.”

Researchers say it’s unknown exactly how VR works to reduce pain levels, but one explanation is simple distraction.

“When the mind is deeply engaged in an immersive experience, it becomes difficult, if not impossible, to perceive stimuli outside of the field of attention. By ‘hijacking’ the auditory, visual, and proprioception senses, VR is thought to create an immersive distraction that restricts the mind from processing pain,” said Spiegel.

Because the VR therapy was only 15 minutes long, Spiegel says lengthening the period of pain reduction might require sustained and repeated exposure to a variety of virtual reality content.

Another small study of VR therapy, published in PLOS, found that just five minutes of exposure to a virtual reality application reduced chronic pain by an average of 33 percent.

VR therapy is not for everyone. It may induce dizziness, vomiting, nausea or epileptic seizures, so patients have to be screened and monitored for side effects. Another barrier is age related. Two-thirds of the people who were eligible for the Cedars-Sinai study were unwilling to try VR therapy, particularly older individuals.  

A larger study is underway at the hospital to measure the impact of VR therapy on the use of pain medications, length of hospital stay and post-discharge satisfaction scores.

The Pain RelieVR game was created by AppliedVR , a Los Angeles based company that is developing a variety of virtual reality content to help treat pain, depression and anxiety. Below is a promotional video released by the company.
