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.

How to Successfully Use Manual Therapy with EDS

By Ellen Lenox Smith, Columnist

There are two types of physical therapy to consider. The traditional type includes ice, hot packs, ultrasound and exercises. With this type, the physical therapist is not touching you.

But for those of us living with Ehlers-Danlos syndrome (EDS), the second type of physical therapy, called manual therapy, is much safer. You lie on a table for a hands-on approach, and the physical therapist has specific techniques to reduce the muscles spasms and realign the bones through touching the patient. It’s similar, but not the same as massage or a chiropractic adjustment.

In EDS sufferers, when our muscles go into spasm, we feel a lot of discomfort and pain, and our joints can shift out of position, causing what is called subluxations.

Even simple tasks like sleeping in a bad position or picking up groceries can cause this. Our poor muscles spasm easily because they are overworked from taking on the job of our ligaments and tendons, which are weakened by our collagen disorder.

We need to realign the joints and return them to their correct position, which then reduces the muscle spasms.

When this is done by a manual physical therapist or chiropractor, then exercising will not hurt so much. Treatment of the muscles repositions the joints and calms the muscle spasms down.

But you also need to understand that your muscles will return to those spasms if another step is not taken after manual therapy.

You need to do specific exercises to strengthen the muscles that were causing the problem. If you just put the joint back into position without strengthening the muscles around it, you will leave the joints weak and susceptible to the same forces that could pull them back out again. If you strengthen the muscles, the joints will not shift out of position so easily. The exercises should begin as soon as the manual therapy appointment is over.

Also, when you have any cranial or myofascial release work done, the process literally puts your muscles into a calmer, sleeping mode. Before leaving the office, you need to reactivate and wake those muscles back up or you will find your joints will potentially slip back out again.

I went to manual therapy for years and never understood why I kept slipping right apart. I would walk out feeling so relaxed and calm and then, sometimes in the car ride home, things would start to shift out of position. Now I take a few minutes to wake up and reactivate the muscles and find the body will hold much longer.

This is a simple procedure that your provider should be able to show you how to do. It makes all the difference in the world. I recommend Kevin Muldowney’s book, Living Life to the Fullest with Ehlers-Danlos Syndrome for proper guidance on these exercises.

Strengthening the muscles is a must after manual therapy or the spasms will return. If you fail to discipline yourself and do your exercises, you can’t expect your provider to develop and assist you in executing a successful treatment plan.

It reminds me of the time my neck was fused. On day three in the hospital, I received an email of instructions from my surgeon. He clearly stated that he had now accomplished his job with the surgery and it was up to me to get out of bed, start walking, and take on the responsibility of helping myself heal and strengthen. It is often difficult for us to accept that we bear the lion's share of the responsibility in any successful treatment plan, but we do!

Mediterranean Diet May Reduce Pain Caused by Obesity

By Pat Anson, Editor

Eating a Mediterranean diet rich in anti-inflammatory foods could decrease the chances an overweight person will develop chronic pain, according to a small study at The Ohio State University.

“We found that a healthy diet explained the link between weight and pain and specifically that seafood and plant proteins such as peas and nuts and beans were key,” said Charles Emery, a professor of psychology at Ohio State’s Institute for Behavioral Medicine Research.

“It appears to be telling us that it’s not just the quantity of the food you eat that plays a role in pain for heavier individuals, but the quality of food as well.”

Emery and his colleagues developed a model to help determine which foods in a Mediterranean diet play a role in the likelihood a person’s weight would contribute to pain.

They found a clear pattern: eating more fish and plant-based proteins such as nuts and beans was linked with less pain, regardless of body weight.

The study, published in the journal Pain, also upheld previous research showing that people who are overweight or obese are more likely to experience pain.

“Obesity and pain are significant public health problems. This was an attempt to take a very detailed snapshot of how they might be related,” Emery said. “We were interested in the possibility of an inflammatory mechanism explaining the connection because we know there’s a high degree of inflammation associated with obesity and with pain.”

Emery’s research team asked 98 men and women between the ages of 20 and 78 detailed questions about their diet and pain levels while visiting them in their homes. They also measured their body mass index, waist circumference and body fat percentage.

Participants who consumed more anti-inflammatory proteins had lower pain levels.

“For people with obesity, it’s kind of like a cloud hanging over them because they experience high levels of pain and inflammation,” Emery said.

Potential weaknesses of the study include the lack of blood samples that would allow the researchers to look at inflammatory markers. Participants were also only asked about their pain  during the previous month, which does not account for chronic pain of a longer duration.

Emery said his next step is to examine body fat and pain using biomarkers associated with inflammation.

“I’m interested in how our work can contribute to effective treatments for overweight and obese individuals,” he said.

A previous study at Ohio State found that anti-inflammatory diets can boost bone health, prevent fractures and lower the risk of osteoporosis in women.

What Cavemen Used for Pain Relief

By Pat Anson, Editor

Neanderthals may be a lot smarter than we give them credit for. Especially when it comes to finding pain relief.

Ancient DNA extracted from the dental plaque of Neanderthals has revealed new insights into their behavior and diet, including their use of plant-based medicine to treat pain and illness.

An international team of researchers compared dental plaque from the jawbones of four Neanderthals found at ancient cave sites in Belgium (Spy Cave) and Spain (El Sidrón Cave). The four samples range from 42,000 to around 50,000 years old and are the oldest dental plaque ever to be genetically analyzed.

“Dental plaque traps microorganisms that lived in the mouth and pathogens found in the respiratory and gastrointestinal tract, as well as bits of food stuck in the teeth – preserving the DNA for thousands of years,” says Dr. Laura Weyrich, a research fellow at the University of Adelaide’s Australian Centre for Ancient DNA (ACAD), who was lead author of the groundbreaking study reported in the journal Nature.

RESEARCHERS IN EL SIDRON CAVE

“Genetic analysis of that DNA ‘locked-up’ in plaque, represents a unique window into Neanderthal lifestyle – revealing new details of what they ate, what their health was like and how the environment impacted their behavior.”

The researchers found that Neanderthals from Spy Cave were mostly meat eaters who consumed wooly rhinoceros and wild sheep, and supplemented their diet with wild mushrooms.

“Those from El Sidrón Cave on the other hand showed no evidence for meat consumption, but appeared instead to have a largely vegetarian diet, comprising pine nuts, moss, mushrooms and tree bark – showing quite different lifestyles between the two groups,” said professor Alan Cooper, Director of ACAD.

The analysis of one Neanderthal found at El Sidrón revealed another surprise. He probably had pain from a dental abscess on his jawbone, and also had signs of an intestinal parasite that causes acute diarrhea.

“Clearly he was quite sick. He was eating poplar, which contains the pain killer salicylic acid, and we could also detect a natural antibiotic mold not seen in the other specimens,” said Cooper. “Apparently, Neanderthals possessed a good knowledge of medicinal plants and their various anti-inflammatory and pain-relieving properties, and seem to be self-medicating.”

Salicylic acid is the active ingredient in aspirin; while certain types of mold – such as Penicillium – help the body fight off infections.

JAWBONE OF NEANDERTHAL FOUND IN EL SIDRON CAVE

“The use of antibiotics would be very surprising, as this is more than 40,000 years before we developed penicillin. Certainly our findings contrast markedly with the rather simplistic view of our ancient relatives in popular imagination,” says Cooper.

The researchers also found that Neanderthals and modern humans shared several disease-causing microbes, including the bacteria that cause dental cavities and gum disease.

Types of bacteria were closely associated with the amount of meat in the diet, with the Spanish Neanderthals grouping with ancient human ancestors in Africa. In contrast, the Belgian Neanderthal bacteria were similar to early hunter gatherers, and quite close to modern humans and early farmers.

“Not only can we now access direct evidence of what our ancestors were eating, but differences in diet and lifestyle also seem to be reflected in the commensal bacteria that lived in the mouths of both Neanderthals and modern humans,” said Professor Keith Dobney of the University of Liverpool.

“Major changes in what we eat have, however, significantly altered the balance of these microbial communities over thousands of years, which in turn continue to have fundamental consequences for our own health and well-being. This extraordinary window on the past is providing us with new ways to explore and understand our evolutionary history through the microorganisms that lived in us and with us.”

Can Reading Help Relieve Chronic Pain?

By Pat Anson, Editor

A good book is not only hard to put down -- it may also help relieve symptoms of chronic pain by triggering positive memories, according to a small British study.

Researchers at the University of Liverpool brought together a group of ten people with severe chronic pain once a week to read literature together aloud. The reading material included short stories, novels and poetry, and covered a wide variety of genres and topics.

While passages were read aloud in the “Shared Reading” exercise, regular pauses were taken to encourage participants to reflect on what is being read, on the thoughts or memories it stirred, and how the reading matter related to their lives.

Researchers compared the Shared Reading group to another group practicing a form of cognitive behavioral therapy (CBT).

While participants in the CBT group were encouraged to manage their emotions by focusing on the pain experience, Shared Reading encouraged pain sufferers to recall positive memories from their past before the onset of chronic pain.

"Our study indicated that shared reading could potentially be an alternative to CBT in bringing into conscious awareness areas of emotional pain otherwise passively suffered by chronic pain patients,” said Josie Billington, a researcher at the University’s Centre for Research into Reading, Literature and Society.

"The encouragement of greater confrontation and tolerance of emotional difficulty that Sharing Reading provides makes it valuable as a longer-term follow-up or adjunct to CBT's concentration on short-term management of emotion."

Researchers say Shared Reading has a therapeutic effect because it helps participants recall a variety of life experiences -- from work, childhood, family and relationships -- not just memories that involve chronic pain.

The study, published in the BMJ Journal for Medical Humanities, was funded by the British Academy.

While many pain sufferers are deeply skeptical of CBT, meditation and similar forms of “mindfulness” therapy, there is evidence that they work for some. A recent study found that CBT lessened pain and improved function better than standard treatments for low back pain.

Another study at Wake Forest University found that mindfulness meditation appears to activate parts of the brain associated with pain control.

Active Seniors Have Lower Risk of Chronic Pain

By Pat Anson, Editor

Older adults who are physically active are better able to block pain signals and may have a lower risk of developing chronic pain, according to a small study published in the journal Pain.

Researchers at Indiana University-Purdue University Indianapolis performed a series of experiments on 51 healthy adults, aged 60 to 77, who wore monitoring devices for one week to measure their physical activity. Participants were given heat and pressure tests to measure their “pain modulation” – how the central nervous system interprets and perceives pain.

Both tests found that pain modulation was significantly related to physical activity. Older adults with more frequent moderate-to-vigorous physical activity had lower pain scores, while those who were sedentary were less able to block pain signals. Even light physical activity appeared to lower pain perception.

"This study provides the first objective evidence suggesting that physical activity behavior is related to the functioning of the endogenous pain modulatory systems in older adults," wrote lead author Kelly Naugle, PhD, of the Center for Physical Activity in Wellness and Prevention, Indiana University–Purdue University Indianapolis.

"Our data suggest that low levels of sedentary behavior and greater light physical activity may be critical in maintaining effective endogenous pain inhibitory function in older adults."

Previous studies have shown that pain modulation is poor in patients with chronic pain conditions such as arthritis, back pain and fibromyalgia.

Aging is associated with chronic low-grade inflammation and oxidative stress, which could make the peripheral and central nervous systems more sensitive to pain. Older adults are also more likely to be sedentary and less physically active, which would make them more vulnerable to chronic pain.

Recent studies have documented the benefits of exercise for older adults. Chair yoga reduced pain and improved the quality of life in older adults with osteoarthritis. Another study found that just 45 minutes of moderate exercise a week improved function and reduced pain levels.  

Stay Engaged Socially If You Are Chronically Ill

By Barby Ingle, Columnist  

It is so important to stay active with your social life when you are living with chronic pain or a disabling chronic condition. It is so easy to isolate ourselves, which can lead to an increase in anxiety, depression and frustration.

Work at not isolating yourself from friends and family. Here are a few ideas that my husband/caregiver and I use:

For Patients:

  • If prayer is helpful, keep doing it
  • Keep exercising (or start)
  • Look for support wherever you can find it
  • Maintain a healthy lifestyle
  • Socialize as much as possible
  • Take in good nutrition
  • Remember your caregivers are going through similar challenges

For Caregivers:

  • If a patient is grouchy or depressed, don’t see it as an attack on you but as a reflection of their pain
  • Learn as much as you can about the patient’s condition and the available medical options
  • Remember the patient is not doing this on purpose and is going through many challenges
  • Try not to take a patient’s anti-social behavior personally
  • Try to avoid being either too babying or too harsh toward a patient
  • A patient may feel less guilty if the burden does not always fall only on you. Try to find others to help with their care.

For Both of You:

  • Discuss options with a loved one when they are ready to talk about them.
  • Join or form a support group. This may be other family members or friends. This will allow you to take a break.

I believe that human connection is so important. When we connect with others and when we have support, we cope better, our pain levels don’t flair as often, and many other health benefits kick in.

We are meant to interact and be a part of society.

I have worked with many chronic pain patients over the years who isolated themselves. Either they or their caregiver came to me asking, “How do I get past this depression?” or “How do I get past all I have lost?”

One woman, who became a good friend over the last 10 years, was injured in her early years of life. She didn’t realize she was isolating herself and that she had stopped maturing psychologically or connecting with others.

Slowly and over time, she changed her patterns of social interaction, concentrated on her feelings, and practiced better daily living (posture, nutrition, stopped smoking). I encouraged her and her caregivers to be more social and pay more attention their feelings. She is now a social butterfly, both online and offline! 

I am also aware that social media or negative online support groups can be very draining when you don’t put up limitations and pay attention to your energy levels.

Find a good balance in life whether you are the patient or their caregiver. Remember you too can have a more meaningful social life that can make a difference for you and everyone around you.

Pain Research Moving at Snail’s Pace

By Pat Anson, Editor

It often seems like research into new treatments for chronic pain are moving at a snail’s pace.

That's literally the case at the University of Utah,  were scientists are studying conus regius, a small marine cone snail found in the Caribbean Sea. The snail's venom is so potent that it paralyzes and kills its prey.

Researchers have isolated a compound in the snail's venom – called Rg1A4 – that has anesthetic effects that last far longer than opioid pain medication.

When injected into laboratory rats, the compound is cleared from the animal’s body in 4 hours, but its analgesic effect still works 72 hours later.

The duration of that pain relieving effect suggests that Rg1A4 has a restorative effect on some components of the nervous system.

UNIVERSITY OF UTAH PHOTO

"What is particularly exciting about these results is the aspect of prevention," said J. Michael McIntosh, MD, a professor of psychiatry at the University of Utah Health Sciences. "Once chronic pain has developed, it is difficult to treat. This compound offers a potential new pathway to prevent pain from developing in the first place and offer a new therapy to patients who have run out of options."

Most pain medications available today work through a limited number of neural pathways and are not sufficient to completely alleviate chronic pain. Opioids also have risky side effects, such as addiction and respiratory depression.

"RgIA4 works by an entirely new pathway, which opens the door for new opportunities to treat pain," said McIntosh. "We feel that drugs that work by this pathway may reduce burden of opioid use."

Researchers around the world are studying the potential medical benefits of cone snail venom. In addition to its analgesic effects, German scientists have found that peptides in the venom decompose quickly and are unlikely to cause dependency.

A pharmaceutical drug derived from cone snails has already been developed and is marketed under the brand name Prialt. The drug is injected in spinal cord fluid to treat severe pain caused by failed back surgery, injury, AIDS, and cancer.

Magnetic Implant Could Someday Deliver Medication

By Pat Anson, Editor

Over the years scientists have developed a variety of drug delivery systems designed to help patients take medications more safely – from pumps to implants to pills made with abuse-deterrent formulas.

Researchers at the University of British Columbia have now developed one of the strangest ones yet -- a magnetic drug implant -- that could offer an alternative for pain patients who don’t like pills or injections and fear the idea of having a pain pump installed.

“This could one day be used for administering painkillers, hormones, chemotherapy drugs and other treatments for a wide range of health conditions. In the next few years we hope to be able to test it for long-term use and for viability in living models,” said Mu Chiao, PhD, a professor of mechanical engineering at UBC.

COURTESY UBC

The magnetic device – a silicone sponge with magnetic carbonyl iron particles wrapped in a polymer layer – is just six millimetres (about a quarter of an inch) in diameter. The drug is injected into the device and then surgically implanted in the area being treated.

Researchers tested the device on animal tissue in the lab using the prostate cancer drug docetaxel. They found that it was able to deliver the drug on demand even after repeated use. The drug also produced an effect on cancer cells comparable to that of freshly administered docetaxel, proving that drugs stored in the device remain effective.

Passing a magnet over the patient’s skin activates the device by deforming the sponge and triggering the release of the drug into surrounding tissue.

The University of British Columbia released this short video to show how it works:

“Drug implants can be safe and effective for treating many conditions, and magnetically controlled implants are particularly interesting because you can adjust the dose after implantation by using different magnet strengths. Many other implants lack that feature,” said Ali Shademani, a PhD student in the biomedical engineering program at UBC, who was lead author of a study published in the journal Advanced Functional Materials.

Implants such as Probuphine – which was approved last year by the Food and Drug Administration to treat opioid addiction -- cannot be adjusted to deliver different medication levels once they are implanted.

The UBC researchers say actively controlling drug delivery is important not only for treating pain, but for conditions like diabetes, where the required dose and timing of insulin varies from patient to patient.

“This device lets you release the actual dose that the patient needs when they need it, and it’s sufficiently easy to use that patients could administer their own medication one day without having to go to a hospital,” said co-author John Jackson, a research scientist in UBC’s faculty of pharmaceutical sciences.

The 411 on Calmare Scrambler Therapy

By Michael Cooney, DC, Guest Columnist

As a chiropractor who treats various pain conditions caused by injury or disease, my biggest frustration is when our therapies do not achieve a successful patient outcome.

Often, “treatment-resistant” patients are forced to seek out more invasive procedures – surgeries, spinal cord stimulators, or powerful narcotics such as ketamine − where success has been uneven, but side effects can be significant.

I wasn’t comfortable recommending these “next level” neuropathic pain treatments for my patients. So my partner Dr. Robert Kelly and I spent two years looking for a non-invasive therapy that didn’t cause pain or come with added side effects.

Through a contact in Italy, we discovered Calmare scrambler therapy, which treats several types of drug and treatment-resistant pain, a big plus for our practice. After undergoing clinical training to use the machine and eventually testing it on patients, we saw results after just a few treatment sessions, in the majority of cases.

I’ll be honest, our aim in adding Calmare to our treatment offerings was designed to help our patients who were not responding to traditional pain therapies. No one was more surprised than I to experience the global interest in this alternative treatment option.

We have been performing Calmare Therapy since 2011, treating patients from coast-to-coast and as far away as Australia, the UK, South Africa and Brazil.

Today, we treat children, adults and seniors battling CRPS/RSD, fibromyalgia, neuropathy after chemotherapy treatment, and pain that develops after surgery or from diabetes. We have also treated many people with neuropathic pain after a shingles diagnosis.

How Scrambler Therapy “Talks” With the Brain

The brain’s reaction to pain can be compared to learning to play the piano or memorizing a poem. The more the body processes pain, the stronger the connections between pain nerves and the brain become.

When someone is injured, the brain sets up a process to heal the injury. For example, cells carry away dead tissue or it increases blood flow to the injured area. Eventually, the brain realizes the injury has healed, and cuts off the pain message.

But for some people, the brain never sends the all-important message: “There’s no more injury here. You can stop sending that pain signal.”

That’s where Calmare scrambler therapy comes in.

Using small electrodes (think EKG pads) judiciously placed in the region of the injury, the device sends a mild electric signal to the brain through the electrodes.

This message overrides the brain’s confused pain signal and corrects it to a “there’s no pain here” message.

We recommend a series of 10 daily scrambler treatments. But in many cases, the pain is lessened for the patient as soon as the first treatment.

The machine we use, the MC-5A Calmare device, has been tested in clinical trials at some of the most prestigious research institutions, including the Massey Cancer Institute at Virginia Commonwealth University, the Mayo Clinic, and the American Society of Clinical Oncology. Their studies reported significant reductions in pain associated with cancer treatment and other chronic pain conditions.

The Value of Alternative Medicine in Treating Neuropathy

The majority of patients we treat with scrambler therapy come to us frustrated and exhausted by the endless search for pain relief. They have often resorted to unproven surgeries, experimental procedures, or have used powerful pain medications that leave them mentally and physically debilitated by the drug’s side effects.

I encourage people with treatment-resistant neuropathy and their families to research and consider less invasive, alternative solutions to combat the effects of chronic pain. In some cases, the cost can be comparable to prescription medications and in-patient co-pays. The outcome can be life-changing.

Regardless of the pain therapy you choose, keep in mind there are treatments that do not involve narcotics, surgery or invasive procedures, which can result in more pain and discomfort.

Keep looking -- network with people who have your medical condition, conduct your own research, and reach out to doctors who understand the value of alternative therapy. Ask the provider to put you in touch with another patient who had the treatment. We enthusiastically offer this service through our Patient-2-Patient program.

There may very well be a solution out there to minimize your pain. But often, it’s up to you to discover it.

Does Changing Your Diet Help With Fibromyalgia?

By Lana Barhum, Columnist

Having lived with fibromyalgia most of my adult life, I know my diet may worsen or improve my pain and other fibromyalgia symptoms. I am not alone in this belief, but the research disagrees. 

Most studies have not shown any specific evidence that fibromyalgia patients should avoid certain foods or add any to their diets to manage symptoms.  Nonetheless, it is still a good idea to take a look at how some foods influence how you feel.

MSG, Gluten and Vitamin D

At least 42% of fibromyalgia patients have reported worsening symptoms after eating certain foods, according to a study in Clinical Rheumatology.  Other studies on fibromyalgia and diet have focused on food additives, gluten, and vitamin D, and found some evidence that they may affect fibromyalgia pain.  

A 2012 study published in Clinical Experimental Rheumatology, assessed fibromyalgia and irritable bowel syndrome (IBS) patients who had excluded monosodium glutamate (MSG) and aspartame from their diets.  After four weeks, 84% of the study participants reported their symptoms had improved by about a third.  Adding MSG back into their diets resulted in a return of symptoms.

The researchers concluded that MSG did, in fact, have an adverse effect on some fibromyalgia patients and removing it from their diets was an easy solution.

"This novel research implicates glutamate as a major adverse excitotoxin in some FM (fibromyalgia) patients. Dietary manipulation is a relatively simple and low cost non-pharmacological intervention that warrants further exploration," reported lead author Kathleen  Holton, PhD.

But another study, published in Rheumatology International, found no relationship between MSG and fibromyalgia pain and symptoms.  The researchers reported no symptom improvement in the group that removed MSG and aspartame from their diets and the group that did not.

While there has been little specific evidence pointing to gluten as a fibromyalgia trigger, some research shows patients respond well when they avoid eating gluten.  Spanish researchers reported in Rheumatology International that fibromyalgia patients who removed gluten from their diets showed notable improvements in pain and symptoms.                                                           

There may also be a link between fibromyalgia pain and low levels of vitamin D, according to a 2014 study out of Austria. That research, reported in the journal Pain, found that study participants who took vitamin D supplements experienced less pain and morning fatigue.   

A 2015 report from the journal Pain and Therapy, also makes a case for a link between Vitamin D deficiency and pain. "Significant improvements in assessment of sleep, mood, pain levels, well-being, and various aspects of quality of life with vitamin D supplementation have been shown,” said researchers Elspeth and Edward Shipton.

More research is needed to further determine if diet and fibromyalgia are actually related.  But doctors do agree eating healthy foods can help patients to feel better and tweaking your diet may improve symptoms.

Making Diet Changes

Here are some ways to help you figure out which foods help and which ones hurt.

Keep a Food Journal.  Many people with fibromyalgia have food sensitivities, but specific “trigger” foods will vary from person to person.  A good way to identify which foods worsen fibromyalgia symptoms and pain is to keep a food journal.  If you find your symptoms consistently worsen after eating certain foods, try eliminating those foods from your diet and see if your symptoms improve.

Eat Healthy. It makes sense for everyone to eat healthy, not just people with fibromyalgia.  Eat a diet that is rich in fruits and vegetables, whole grains, and lean proteins. 

A balanced diet will also give you more energy and improve overall health.

Pick the Right Foods. There are certain foods that may help improve fibromyalgia symptoms and minimize flares.  Vitamin D is one, as studies show deficiency can cause joint and muscle pain.

Vitamin D is one, as studies show deficiency can cause joint and muscle pain. Foods rich in vitamin D include fatty fish (tuna and salmon), dairy products fortified with vitamin D (orange juice, milk, and cereal), beef liver, and egg yolks. Foods containing omega 3 fatty acids, which are found in fatty fish, walnuts and flax seed, may also ease fibromyalgia symptoms by reducing soreness and inflammation.  

My Take

I am strong believer in taking your health into your own hands and experimenting with alternative treatments, including a healthy diet.  Through trial and error, I have figured out which foods help and which foods hurt as I continue to learn how to successfully cope with fibromyalgia. 

Aspartame (Nutrasweet), food additives (especially MSG), sugar, fructose, simple carbohydrates, caffeine, gluten, fried and junk food, dairy and nightshades (tomatoes, peppers, and potatoes) are all foods that I have either eliminated or minimized from my diet.  Cutting them out of my diet has made fibromyalgia flares less frequent. 

In addition, I take vitamin D supplements, since my levels are often low, and eat foods rich in omega 3 fatty acids, such as fish, walnuts, and eggs, to manage inflammation, as I also suffer from rheumatoid arthritis.

While I don’t know for certain if my diet is the reason for fewer flare-ups, I do know that avoiding certain foods and eating healthy ones benefits my overall health.  And when my body feels healthier, I am better able to cope with fibromyalgia pain and symptoms.

The specific foods that help and hurt will be different for you, but a healthy diet can help you manage fibromyalgia symptoms and pain and improve your health overall.  And, it is definitely worth a try to find out.

Acupuncture Effective in Treating Pain and Depression

Acupuncture can boost the effectiveness of medical care and lessen the severity of chronic pain and depression, according to a new study led by British researchers.

In a meta-analysis (a study of studies) of 29 clinical trials involving nearly 18,000 patients with chronic neck, lower back, knee or headache pain, researchers found that acupuncture significantly reduced the severity of pain when combined with standard medical care such as anti-inflammatory drugs.

Acupuncture is an ancient Chinese form of treatment that involves the insertion of fine needles into acupuncture points on the body. About four million acupuncture sessions are provided each year in the UK, about half of them for pain relief. The evidence to support such treatment has been limited.

"There has been a question mark for many years over whether policy and decision makers should or should not provide wider access to acupuncture,” said Hugh MacPherson, PhD, a professor of acupuncture research at the University of York.

“Our aim was to bring together data from high quality clinical trials and provide a robust evidence base that will help reduce this uncertainty and support commissioners and health professionals in making informed decisions backed up with research."

The study, published in the National Institute for Health Research (NIHR) Journals Library, found that the addition of acupuncture -- compared to standard medical care alone -- significantly reduced the number of headaches and migraine attacks and reduced the severity of neck and lower back pain.  Acupuncture also reduced the pain and disability of osteoarthritis, which led to patients using less anti-inflammatory medication to control pain.

The research team also conducted a new clinical trial for depression, in which 755 patients were provided with acupuncture, counseling or antidepressants. They found that both acupuncture and counseling significantly reduced the severity of depression, and that the benefits were sustained up to 12 months after treatment.

"In the largest study of its kind, we have now provided a solid evidence base to show that not only can acupuncture and counseling bring patients out of an episode of depression, but it can keep the condition at bay for up to a year on average," said MacPherson, who added that antidepressants don’t work well for more than half of patients.

Researchers admit the benefits of acupuncture are partially associated with a placebo effect, which has contributed to uncertainty about it's clinical effectiveness. However, when compared with sham acupuncture – in which fake needles are used or inserted in the wrong locations – they say “real” acupuncture provides substantially more pain relief.

“Our new data provides a significant step forward in treating chronic pain and managing depression, because patients and health professionals can now make decisions on acupuncture with more confidence. Not only is it more cost effective, but it reduces pain levels and improves mood levels, which could reduce over reliance on drugs that can sometimes result in unwanted side effects," MacPherson said.

Acupuncture is one of the most widely practiced forms of alternative medicine. As many as 3 million Americans receive acupuncture treatments, most often for relief of chronic pain. While there is little consensus in the medical community about acupuncture’s value, a large study in the Archives of Internal Medicine found that  “acupuncture is effective for the treatment of chronic pain and is therefore a reasonable referral option.”

Early Detection and Diet May Help Prevent Osteoporosis

By Pat Anson, Editor

The key to good bone health – and preventing fractures later in life – may lie in anti-inflammatory diets and earlier detection of bone loss, according to two new studies.

Researchers at the University of Michigan are studying new ways to identify women at risk of osteoporosis, a loss in bone density that raises the risk of fractures and disability. Breaking a bone in your spine or hip doubles your chances of developing chronic widespread body pain, especially if you are older.

"It's been considered a silent disease," says Karl Jepsen, PhD, associate chair of research and professor of orthopaedic surgery at Michigan Medicine. "One of the biggest challenges when you're looking at age-related bone fragility is to identify people who will fracture."

Jepsen is the lead author of a study published in the Journal of Bone and Mineral Research, which followed nearly 200 women for 14 years as they transitioned through menopause.

"Current identification for bone fragility takes place when the patient is around 65 years of age," Jepsen explains.

"We were hopeful that this study would give us an opportunity to identify those patients as early as 30 years before they fracture based on their bone traits. That means we would have an opportunity to intervene before the fracture happens, instead of after the fact."

Jepsen and his colleagues started following the women in 1996. Participants who enrolled had to be between 42 and 52 years of age and had at least one menstrual period in the previous three months. The women had bone density scans and other tests annually to measure changes in their bone mineral density.

Researchers found that the women experienced a wide variation in bone mineral content and bone area within the hip as they went through menopause, a finding that was unexpected.

"Our results were opposite to all expectations of how we assumed this would work," Jepsen says. "We found some women appeared to have hip bones that were increasing in strength during the menopausal transition while others seemed to be losing strength."

Jepsen said his study demonstrates that bone changes can be tracked individually in women during menopause, when treatment can begin earlier to prevent bone loss. Hormones and bisphosphonate drugs are currently used to help strengthen bones.

“Our goal is to use simple bone traits to identify those women that may benefit from early intervention when it comes to bone fragility, instead of the current strategy, which treats individuals after they have lost appreciable bone mass and strength," he said.

Anti-Inflammatory Diet Improves Bone Health

Anti-inflammatory diets -- which tend to be high in vegetables, fruits, fish and whole grains -- could boost bone health and prevent fractures, according to a study at The Ohio State University.

Researchers analyzed dietary data from over 160,000 women enrolled in the landmark Women's Health Initiative by assigning inflammation scores based on 32 foods that the women reported consuming. Researchers also looked at bone-mineral-density data from over 10,000 women and collected fracture data for the entire study group.

They found a correlation between high-inflammatory diets and fractures in post-menopausal younger than 63. Women with the least-inflammatory diets also lost less bone mineral density.

"This suggests that as women age, healthy diets are impacting their bones," said Tonya Orchard, an assistant professor of human nutrition at Ohio State's Food Innovation Center. "These women with healthier diets didn't lose bone as quickly as those with high-inflammation diets, and this is important because after menopause women see a drastic loss in bone density that contributes to fractures,"

The study, which appears in the Journal of Bone and Mineral Research, was observational -- meaning it does not definitively link diet to bone health. But it adds to a growing body of evidence that inflammation can increase osteoporosis risk.

"By looking at the full diet rather than individual nutrients, these data provide a foundation for studying how components of the diet might interact to provide benefit and better inform women's health and lifestyle choices," said Rebecca Jackson, the study's senior author and director of Ohio State's Center for Clinical and Translational Science.

Previous studies have connected high levels of inflammatory markers in the blood to bone loss and fractures in older women and men. The new findings suggest that women's bone health could benefit when they choose a diet higher in beneficial fats, plants and whole grains.

Spinal Cord Stimulators Reduce Opioid Use

By Pat Anson, Editor

Most patients who have a spinal cord stimulator significantly reduce their use of opioid pain medication one year after their implant, according to new industry-funded research.

In an analysis of private and Medicare insurance claims from 5,476 patients who received a spinal cord stimulator (SCS), opioid use declined or stabilized in 70 percent of the patients. Opioid use was higher among patients who had the stimulator removed.

The study, presented at the annual meeting of the North American Neuromodulation Society (NANS), was sponsored by Abbott (NYSE: ABT), a manufacturer of SCS systems and other medical devices.

"Given the epidemic of opioid addiction and abuse, these findings are important and confirm that spinal cord stimulation therapy can offer strong benefits for patients struggling with chronic pain," said Ashwini Sharan, MD, president of NANS and director of Functional and Epilepsy Surgery at Vickie and Jack Farber Institute for Neuroscience.

"Based on these results, we concluded it may be possible to improve outcomes by offering our patients spinal cord stimulation earlier, before opioid dependence and addiction can occur."

Spinal cord stimulators have long been considered the treatment of last resort for chronic back and leg pain, because the devices have to be surgically implanted near the spine and connected to batteries placed under the skin. The implants send electrical impulses into the spine to mask pain.

Some patients find the stimulators ineffective and have them removed. According to one study, only about half of patients who received a traditional SCS device have a 50 percent reduction in their back and leg pain.

New technologies have been developed to make the devices more effective, easier to recharge and to reduce complications such as paresthesia – a tingling or buzzing sensation.

And with government regulators and insurers discouraging the use of opioid pain medication, the medical device industry is urging patients and doctors to take another look at SCS devices.

X-RAY OF PATIENT WITH MEDTRONIC SCS DEVICE

"As our society has been seeking ways to stem opioid abuse and addition, our company offers treatment options that can reduce their exposure to opioid medication," said Allen Burton, MD, medical director of neuromodulation at Abbott in a news release. "Data like these are critical to helping us demonstrate that spinal cord stimulation can reduce exposure to opioids while giving patients comprehensive pain relief."

Abbot recently purchased St. Jude Medical, giving the medical device maker its first exposure to the SCS and neuromodulation market, which has an estimated value of $5.3 billion.

"Non-medical pain relief is a focus with attention on the dangers of pain medication and the need to find alternatives to reduce chronic pain," said Bruce Carlson, Publisher of Kalorama Information, a research firm that tracks the neuromodulation market. "Abbott builds on its cardiovascular device properties with this deal, and that is a big focus of press coverage.  St. Jude's impressive spinal cord offering should not be obscured in this transaction."

Even a Little Exercise Is Better Than None

By Pat Anson, Editor

We often hear from pain sufferers who say they’d like to exercise more, but can’t because their pain levels have left them bedridden or stuck on a couch. Others believe a workout at the gym will only make their pain worse.

But two new studies have found that you don’t need to be a gym rat to get the health benefits from exercise.

You may not even need to stand up!

Federal guidelines suggest a minimum of 150 minutes of exercise a week are needed to promote good cardiovascular health. But researchers at Northwestern University wanted to see if a lesser goal could improve overall health.

They measured the physical activity of 1,600 adults with osteoarthritis in their hips, knees or feet; and found that just 45 minutes of moderate physical activity a week improved their function and reduced pain

"We were interested in seeing what kind of physical activity might be beneficial to promote good function down the road,” said Dorothy Dunlop, a professor of rheumatology and preventive medicine at Northwestern University Feinberg School of Medicine.

“We found moderate-intensity activity rather than light activity, such as pushing a grocery cart, to be more valuable to promote future function."

Using sophisticated accelerometers to monitor movement, the researchers found that participants who engaged in moderate activity, such as brisk walking, for at least 45 minutes a week were 80 percent more likely to improve or sustain high future function.

The findings, published in the journal Arthritis Care & Research., were true for both men and women. The beneficial effects of the exercise were also long term. About a third of participants improved or had high function after two years.

"The federal guidelines are very important because the more you do, the better you'll feel and the greater the health benefits you'll receive," Dunlop said. "But even achieving this less rigorous goal will promote the ability to function and may be a feasible starting point for older adults dealing with discomfort in their joints.”

"Even a little activity is better than none," she added

Chair Yoga Relieves Pain of Osteoarthritis

A second study at Florida Atlantic University found that “chair yoga” is an effective way to reduce pain and improve quality of life in older adults with osteoarthritis.

As the name implies, the Sit-N-Fit Chair Yoga program was developed to help those who cannot stand during exercise or participate in traditional yoga. Chair yoga is practiced sitting in a chair or standing while holding the chair for support.

In a study of 131 older adults who have osteoarthritis, participants attended 45-minute chair yoga sessions twice a week for 8 weeks.

Researchers measured their pain, pain interference (how it affects one's life), balance, gait speed, fatigue and functional ability; before, during and after the sessions.

Compared to a control group enrolled in a health education program, the chair yoga group showed a greater reduction in pain, pain interference and fatigue during the sessions, as well as an improved gait. The reduction in pain interference lasted for about three months after the chair yoga program was completed.

"The effect of pain on everyday living is most directly captured by pain interference, and our findings demonstrate that chair yoga reduced pain interference in everyday activities," said Ruth McCaffrey, emeritus professor in FAU's College of Nursing and co-author of the study published in the Journal of the American Geriatrics Society.

"The potential impact of this study on public health is high, as this program provides an approach for keeping community-dwelling elders active even when they cannot participate in traditional exercise that challenges their balance," said co-author and principal investigator Patricia Liehr, PhD, a professor in FAU's College of Nursing.

Osteoarthritis is the most common form of arthritis and the leading cause of long-term disability in older adults. It affects about a third of Americans over the age of 65.
