MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Chronic low back pain (cLBP) is prevalent among military veterans, but cLBP treatment options have limited benefits and side effects. This has resulted in efforts to reduce opioid use and embrace nonpharmacological pain treatments.

Yoga has been shown to improve health outcomes and have few side effects in non-veteran community samples.

Our objective was to study the effectiveness and safety of yoga for military veterans with chronic low back pain.  In a study of 150 veterans with cLBP, we found that yoga participants had greater reductions in disability and pain than those receiving usual. Opioid medication use declined among all participants, and no serious side effects occurred.

MedicalResearch.com: What is the background for this study?

Response: Pregabalin (PG) and gabapentin (GB) are increasingly used for nonspecific Chronic Low Back Pain (CLBP) despite a lack of evidence. There have been concerns expressed over their increased prescribing for various non cancer pain indications in recent years. Their use requires slow titration to therapeutic doses and establishing maintenance on a long-term basis. With prolonged treatment, the potential gain over possible adverse effects and risks could become unclear.

We searched Cochrane, MEDLINE and EMBASE databases for randomized control trials reporting the use of gabapentinoids for chronic lower back pain treatment of 3 months or more in adult patients.

MedicalResearch.com: What is the background for this study?

Esther Maas, PhD Chronic low back pain causes more disability than any other condition, and has major social and economic consequences. Radiofrequency denervation is a commonly used treatment in pain clinics for a subgroup of patients with chronic low back pain resulting from anatomical structures such as facet joints, sacroiliac joint and intervertebral disc. Radiofrequency denervation uses an electric current that damages the innervating nerve of the painful structure. Despite its frequent application, until now, there was only very low quality and conflicting evidence for its effectiveness. The aim of this study was to establish whether radiofrequency denervation in addition to a standardized exercise program is more effective than the standardized exercise program alone in the selected subgroup of patients with chronic low back pain.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The prevalence of stress urinary incontinence(SUI) is as high as 49% and varies according to the population studied and the definition of stress urinary incontinence.

SUI causes psychological burden, affects relationships, lowers physical productivity, and decreases quality of life in women. Yet, few effective therapies are available for treating stress urinary incontinence.

In this randomized clinical trial that included 504 women, the mean decrease in urine leakage, measured by the 1-hour pad test from baseline to week 6, was 9.9 g with
electroacupuncture vs 2.6 g with sham electroacupuncture, a significant difference.

Yoga As Effective As Physical Therapy For Chronic Low Back Pain

MedicalResearch.com: What is the background for this study?

Response: There are a number of studies that show that yoga is effective for chronic low back pain (cLBP), but those studies included mostly white and middle-class individuals as research participants. cLBP disproportionately impacts those who are economically disadvantaged and minorities; they receive less referrals to specialists, less referrals to rehabilitation, and also less patient-education. Therefore, it was important to test whether yoga would be well- received by an underserved population, as well as be an effective form of treating chronic low back pain.

This study consisted of patients from diverse racial and economic backgrounds with multiple medical problems who were able to successfully participate and benefit from both yoga and physical therapy. This study used yoga classes that were specifically designed for people suffering from  chronic low back pain and compared the results of that treatment to those who did physical therapy.

MedicalResearch.com: What are the main findings?

Response: The results show that the yoga was as effective as physical therapy for reducing pain intensity and improving people’s physical function. Patients in the study who did yoga reported that their overall pain intensity went down, that they were able to be more physically active, and a number of patients were also able to reduce or even stop all of their pain medication. The study shows that when yoga is made available and affordable to a diverse population, people of both sexes, people who are disabled, and people of different races and economic backgrounds are both receptive to yoga and, more importantly, can benefit from it.

MedicalResearch.com: What should readers take away from your report?

Response: Doctors should know that a structured yoga program for cLBP is a reasonable, effective, and safe approach for patients with chronic  chronic low back pain. Patients with cLBP should talk with their doctors about different options for treatment of back pain, starting with non-drug approaches like yoga and physical therapy. Policy makers need to examine the potential benefits for patients and cost savings for covering non-pharmacological approaches to pain.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: The cost effectiveness of yoga and physical therapy for chronic low back pain still needs to be looked at carefully, as well as how the medical community can implement yoga classes for back pain widely.

While medication, imaging and invasive procedures absolutely have their place, research and clinical guidelines show that non-pharmacological procedures as first treatment options may be best.

MedicalResearch.com: Is there anything else you would like to add?

Response: Yoga is increasingly popular in the United States, and many yoga teachers are available in urban areas. However, yoga teachers and yoga classes are still relatively rare in communities of color and disadvantaged areas. Therefore, it’s important that we begin to train, build, and make yoga more available to diverse communities. Changing the common view of yoga from a fitness exercise for the healthy and wealthy, to a therapeutic approach for people with chronic pain and other conditions, is also an ongoing challenge.

Finding that yoga is non-inferior to physical therapy makes a strong case that yoga programs like the one in this study should be covered by insurance and offered by health care facilities. When a therapy like yoga is shown to be as effective as standard therapies, it should be made available to everyone regardless of ability to pay. For patients who attended more classes or physical therapy sessions, their cLBP improvement was even greater.

Dr. Makris is a Rheumatologist, clinically, and spends the majority of time focused on clinical research investigating how to improve outcomes for adults with back pain.

MedicalResearch.com: What is the background for this study?

Response: Back pain is the most common type of musculoskeletal (MSK) pain. We know that expenditures for back pain exceed $100 billion each year (and this was in 2005). Back pain results in tremendous disability (including reduced mobility) and impaired quality of life (not exclusive to physical consequences, but also including important psychosocial repercussions). We also know that statins are prescribed very often, and frequently in younger populations who are active. Some reports suggest that statins may have a protective effect on  musculoskeletal conditions such as back pain.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Back pain is one of the commonest symptoms for adult patients to seek health care. For a number of years now, VA has had chiropractic care integrated into the ambulatory care available at many large VA medical centers. Most patients referred from VA primary care to chiropractic clinic have chronic back pain. VA was interested in an evidence synthesis of the use of spinal manipulative therapy in acute low back pain. Spinal manipulative therapy is a manual technique delivered by almost all chiropractors, but also delivered by some physical therapists, osteopathic physicians, and some medical doctors.

The main findings are that spinal manipulative therapy is associated with, on average, a modest beneficial effect on pain and function. However, there are large difference sin outcome across studies, and this suggests that some patients may respond much better, and other may respond not at all.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We previously reported the results of a randomized trial examining the effectiveness of Mindfulness-based stress reduction (MBSR) and cognitive behavioral therapy (CBT) for persons with chronic low back pain (Cherkin et al, JAMA, March 22, 2016).

The current report examines whether the relative effectiveness of these approaches compared with usual care that we found after one year were still evident after two years. We found that there was little decrease in the magnitude of the effects of both MBSR and CBT between one and two years, but the two-year outcomes were statistically significant only for chronic low back pain. As previously reported for outcomes up to one year, there were no significant differences in outcomes between CBT and MBSR.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: People with back pain are usually told by their health care practitioners to take analgesic medications to relieve their pain. But our previous research published in the BMJ showed that paracetamol does not have a measurable impact on patient’s symptoms. This resulted in recent changes in guidelines’ recommendations. The 2017 National Institute for Health and Care Excellence (NICE) guidelines/UK no longer recommend paracetamol as a stand-alone intervention for back pain.

So now non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as the analgesic of first choice. However, our results show that compared to placebo, commonly used NSAIDs, such as Ibuprofen (e.g. Nurofen) and Diclofenac (e.g. Voltaren), provide only small benefits for people with back pain while increasing the risk of gastrointestinal adverse effects by 2.5 times.

Medical Research: What is the background for this study?

Dr. Steffens: Back pain is a leading cause of disease burden globally. At present, a variety of interventions, such as exercise, education, back belts and shoe insoles, are commonly prescribed to prevent an episode of low back pain. Guidelines lack clear recommendations for prevention of low back pain and the effectiveness of the range of possible prevention strategies for low back pain is not clear. Our study aimed to investigate the effectiveness of these interventions for prevention of low back pain.
