A systematic review and meta-analysis of yoga for low back pain. Clin J Pain. 2013;29:450-460. [PMID: 23246998 DOI: 10.1097/AJP.0b013e31825e1492]

Formulation of Japanese Orthopaedic Association (JOA) clinical practice guideline for the management of low back pain- the revised 2019 edition

BACKGROUND

The latest clinical guidelines are mandatory for physicians to follow when practicing evidence-based medicine in the treatment of low back pain. Those guidelines should target not only Japanese board-certified orthopaedic surgeons, but also primary physicians, and they should be prepared based entirely on evidence-based medicine. The Japanese Orthopaedic Association Low Back Pain guideline committee decided to update the guideline and launched the formulation committee. The purpose of this study was to describe the formulation we implemented for the revision of the guideline with the latest data of evidence-based medicine.

METHODS

The Japanese Orthopaedic Association Low Back Pain guideline formulation committee revised the previous guideline based on a method for preparing clinical guidelines in Japan proposed by Medical Information Network Distribution Service Handbook for Clinical Practice Guideline Development 2014. Two key phrases, "body of evidence" and "benefit and harm balance" were focused on in the revised version. Background and clinical questions were determined, followed by literature search related to each question. Appropriate articles were selected from all the searched literature. Structured abstracts were prepared, and then meta-analyses were performed. The strength of both the body of evidence and the recommendation was decided by the committee members.

RESULTS

Nine background and nine clinical qvuestions were determined. For each clinical question, outcomes from the literature were collected and meta-analysis was performed. Answers and explanations were described for each clinical question, and the strength of the recommendation was decided. For background questions, the recommendations were described based on previous literature.

CONCLUSIONS

The 2019 clinical practice guideline for the management of low back pain was completed according to the latest evidence-based medicine. We strongly hope that this guideline serves as a benchmark for all physicians, as well as patients, in the management of low back pain.

Designing, validation, and feasibility of a yoga module for patients with ankylosing spondylitis

BACKGROUND

Ankylosing spondylitis (AS) is a chronic inflammatory disease that causes significant disability and reduced quality of life. Scientific studies on yoga have revealed its various health benefits in chronic conditions, including autoimmune diseases. However, whether yoga is feasible for AS patients or not is not studied. Further, no validated yoga module is available for AS patients.

OBJECTIVE(S)

This study intended to develop a yoga module for AS patients and investigated its feasibility of use.

MATERIALS AND METHODS

The study was completed in three stages. In Stage I, six yoga experts prepared a list of 64 yoga practices based on the classical and contemporary yogic literature review. Of these practices, 41 were included in the designed yoga module. In Stage II, 41 experts with a minimum of five years of experience in yoga therapy were invited for yoga module validation. The usefulness of the practices was rated by experts on a 3-point scale (1: not at all useful, 2: moderately useful, and 3: very much useful). The Lawshe content validity ratio (CVR) method was used for the content validity of the yoga module. Practices with a CVR score of > 0.3 were retained in the final yoga module. In Stage III, a certified yoga instructor administered the validated yoga module to 19 AS patients (average age: 35.5 ± 10.7 years) thrice weekly for a month. Feasibility was assessed on the basis of the attrition rate, retention rate, attendance of the participants, and the subjective response on practical sessions using a structured checklist.

RESULTS

Of the 41 practices in the module, 31 had a CVR score of > 0.3 and were included in the final yoga module. Of the 25 participants, 19 (76%) completed the study while six dropped out (24%). Nineteen patients reported greater improvement in pain and flexibility. They found yoga relaxing and easy to practice. Most participants (65%) were able to practice a minimum of 30 min/day.

CONCLUSION

The present study offers a validated yoga module consisting of 31 practices for AS patients. The results of the pilot suggested that the module is feasible, acceptable, and easy to practice for AS patients. We recommend that AS patients should practice this yoga module for a minimum of 30 min every day under the supervision of a yoga expert.

[Noninvasive Treatments for Acute and Chronic Back Pain]

Noninvasive Treatments for Acute and Chronic Back Pain Abstract. The therapy of back pain - especially the medication with opioids - can be challenging for the treating physician. Specific back pain can often be diagnosed by imaging and successfully treated by surgery or medication. In contrast, nonspecific back pain can be worsened by inappropriate imaging, questionable surgical indications and uncontrolled drug use. For the therapy of nonspecific back pain, maintaining daily activity and exercise therapy is central. Opioids are effective drugs for short-term use. However, long-term use often leads to opioid-induced hyperalgesia and hormonal dysfunction with decreased quality of life and libido. Furthermore, opioids can lead to abuse and addiction. After an ineffective treatment with non-opioids, opioids may be given for a limited time period (if possible shorter than four weeks) according to international guidelines.

Participant-perceived occupational outcomes after two years of yoga for chronic pain

Introduction

The study aim was to investigate the perceived impact and experience of long-term involvement in community-based group yoga for people with chronic pain.

Methods

Eleven participants, who previously completed an 8-week yoga intervention and continued attending yoga at a community pain clinic for 2 years, participated in the study. A mixed-methods approach was employed. Canadian Occupational Performance Measure data were collected during the 8-week yoga study (baseline) and after 2 years of yoga (follow-up). Baseline and follow-up Canadian Occupational Performance Measure data were compared to measure change in perceived occupational performance and satisfaction. Individual qualitative interviews were conducted to explore participants’ perceived impact and experience of long-term yoga involvement. Canadian Occupational Performance Measure data were analyzed using Wilcoxon signed-rank tests, and qualitative interviews were analyzed using an inductive approach.

Findings

Canadian Occupational Performance Measure scores significantly improved between baseline and follow-up. Three main themes emerged from qualitative interviews: (a) Occupational shift from “existing” to “living,” (b) The change process is “progressive,” and (c) Yoga is “a positive thing I do in my life.”

Conclusion

Long-term involvement in community-based group yoga may improve and sustain occupational performance and satisfaction. Occupational therapists may consider yoga as a tool to promote occupational gains in people with chronic pain.

Effectiveness and safety of yoga to treat chronic and acute pain: a rapid review of systematic reviews

Background

Pain is a sensation of discomfort that affects a large part of the population. Yoga is indicated to treat various health conditions, including chronic and acute pain.

Objective

To evaluate the effectiveness and safety of yoga to treat acute or chronic pain in the adult and elderly population.

Study selection

A rapid review was carried out, following a protocol established a priori. Searches were carried out in September 2019, in six databases, using PICOS and MeSH (Medical Subject Headings) and DeCS (Descritores em Ciências da Saúde) terms. Systematic reviews were included, and methodological quality was assessed using Assessing the Methodological Quality of Systematic Reviews. The results were presented in a narrative synthesis.

Findings

Ten systematic reviews were selected. Two reviews were assessed as of high methodological quality, two as of low quality, and six of critically low quality. Results were favourable to yoga compared with usual daily care, particularly in low back and cervical pain cases. There was little evidence about the superiority of yoga compared with active interventions (exercises, pilates or complementary and complementary medicine). It was also less consistent in pain associated with fibromyalgia, osteoarthritis, rheumatoid arthritis, carpal tunnel and irritable bowel syndromes. There was an improvement in the quality of life and mood of the participants, especially for yoga compared with usual care, exercises and waiting list.

Conclusions

Overall, the results were favourable to yoga compared with usual care in low back and cervical pain cases. The evidence is insufficient to assert yoga’s benefits for other pain conditions, as well as its superiority over active interventions. The findings must be considered with caution, given their low methodological quality and the small samples in the primary studies reported in the included systematic reviews. Thus, more studies must be carried out to improve the reliability of the results.

"A study protocol for a randomised controlled trial on the efficacy of yoga as an adjuvant therapy for patients with Ankylosing spondylitis amidst COVID-19 pandemic"

Background

Amidst the adversities of the COVID-19 pandemic, the health care system has seen a new paradigm shift towards e-health or telehealth services. In the advent of catering to the geometrically increasing health care needs of the patients suffering from various chronic health conditions when in social isolation, the need for such shifts is paramount. Patients with Ankylosing spondylitis using immunosuppressants with variable degrees of disabilities are at higher risk from this isolated status. This study aims to assess the efficacy of e-Yoga as a treatment option for these patients.

Methods

The proposed study is a single-center, parallel-group prospective randomized, open-blinded end-point trial. Patients aged between 30 and 50 years will be recruited from the members of Antardhwani: A society of ankylosing spondylitis based in Ahmedabad, Gujarat. Yoga experts will administer a scientifically developed and validated Yoga module via e-Yoga modalities. A total of 135 patients will be recruited and randomly allocated to Yoga and control groups. Data will be recorded at baseline and three months on disease activity, degree of functional limitations in patients, quality of life, inflammatory biomarkers, depression, and anxiety using Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), AS Quality of Life index (ASQOL), C reactive protein (CRP), Erythrocyte sedimentation rate (ESR), Physical health questionnaire-4 (PHQ-4), respectively.

Discussion

The study will report the efficacy of e-Yoga in catering to the physical and mental insufficiencies of inpatients with Ankylosing spondylitis amidst COVID-19 pandemic. The study is prospectively registered in the Clinical Trial Registry of India (CTRI/2020/08/027215)

Yoga for treating low back pain: a systematic review and meta-analysis

ABSTRACT

Yoga is frequently used for back pain relief. However, evidence was judged to be of only low- or moderate. To assess the efficacy and safety of yoga in patients with low back pain a meta-analysis was performed. Therefore Medline/PubMed, Scopus, and the Cochrane Library was searched to May 26 2020. Only randomized controlled trials (RCTs) comparing Yoga with passive control (usual care or waitlist), or an active comparator, for patients with low back pain, that assessed pain intensity or pain-related disability as a primary outcome were considered to be eligible. Two reviewers independently extracted data on study characteristics, outcome measures, and results at short-term and long-term follow-up. Risk of bias was assessed using the Cochrane Risk of Bias Tool. 30 articles on 27 individual studies (2702 participants in total) proved eligible for review. Compared to passive control, yoga was associated with short-term improvements in pain intensity (15 RCTs; Mean Difference (MD)=-0.74 points on a numeric rating scale; 95%CI=-1.04,-0.44; Standardized Mean Difference (SMD)=-0.37 95%CI=-0.52,-0.22), pain-related disability (15 RCTs; MD=-2.28; 95%CI=-3.30,-1.26; SMD=-0.38 95%CI=-0.55,-0.21), mental health (7 RCTs; MD=1.70; 95%CI=0.20,3.20; SMD=0.17 95%CI=0.02,0.32) and physical functioning (9 RCTs; MD=2.80; 95%CI=1.00,4.70; SMD=0.28 95%CI=0.10,0.47). Except for mental health all effects sustained long-term. Compared to an active comparator, yoga was not associated with any significant differences in short- or long-term outcomes.In conclusion, yoga revealed robust short- and long-term effects for pain, disability, physical function and mental health, when compared to non-exercise controls. However these effects were mainly not clinically significant.

A qualitative study exploring middle-aged women's experiences with yoga

The purpose of this study was to explore how yoga impacts body-related thoughts, feelings, perceptions and attitudes, well-being, and self-care behaviors in a sample of middle-aged women who regularly engage in yoga in their communities. The sample included 22 women; 10 self-identified as beginners or novices and 12 self-identified as experienced in yoga. Interpretive phenomenological analysis guided the data collection, analysis, and interpretation. Four key themes were identified around the topics of: supportive yoga environment, mindfulness, self-care behaviors, and body-related perceptions. Results highlight potential elements of yoga that can support positive body-related experiences in middle-aged women.

A wellbeing skill: moving attentively in hospital yoga practice

Yoga is sometimes interpreted as medical therapy and the evidence from biomedical research indicates that it can be useful in a broad range of health conditions. Yoga, however, can also be pursued as a process-oriented contemplative practice. This article draws on participant observation-based research with yoga practitioners at two hospitals, one in Pondicherry, India, and one in Fukui, Japan. It explores how patients and their families at these healthcare institutions are invited to move without anticipating an outcome and to cultivate attitudes such as contentment and non-violence. Taking cues from research participants' approaches to yoga as a skill and from anthropological understandings of skill, yoga is considered here as a capacity of moving with awareness. A skill-based approach allows practitioners to try out yogic techniques according to their personal abilities and needs. The analysis suggests that, in the contexts discussed, yoga practitioners pursue wellbeing not as an individual therapeutic goal but as mutual explorative learning.

Complementary and Alternative Modalities (CAM) for pain management in musculoskeletal diseases (MSDs)

Musculoskeletal diseases are a group of clinical conditions affecting the body's movement and remain a common source of pain affecting the quality of life. The aetio-pathological reasons for pain associated with musculoskeletal diseases can be varied and complex. Conventional medicine can treat or modify pain due to musculoskeletal diseases; however, these may be associated with some side effects and at times may not be able to relieve pain completely. These treatment modalities also have ceiling effects like doses of analgesics, the number of nerve blocks, etc. Complementary and Alternative Medicine (CAM) provides a supplementary, unconventional modality to alleviate discomfort and disability associated with these mostly chronic conditions to manage activities of daily living. These modalities have been variedly combined with conventional management for symptom control and thus improve day-to-day activities. We assess the role of commonly used CAM modalities in the management of pain arising from Musculoskeletal diseases.

Lifestyle Medicine for Chronic Lower Back Pain: An Evidence-Based Approach

Lower back pain is a leading cause of work absence and activity limitations globally, with a 60% to 85% lifetime chance of occurrence. This article highlights the role that lifestyle medicine plays in managing lower back pain as a cost-effective intervention strategy. It is suggested that lifestyle medicine strategies, such as incorporating whole foods and a plant-based diet, sustainable physical activity and mind-body exercises, restorative sleep, stress resiliency, awareness and mitigation of substance abuse and addiction, and establishing meaningful social networks and self-care strategies, be a part of managing chronic lower back pain.

A systematic review of the effectiveness of yoga on pain, physical function, and quality of life in older adults with chronic musculoskeletal conditions

OBJECTIVES

Exercise interventions suitable for older adults can help to slow and manage age-related conditions. This systematic review looks at age-related musculoskeletal conditions in a population with a mean age over 50 years, evaluating the effectiveness of yoga for pain, physical function, and quality of life.

METHODS

CENTRAL,CINAHL, Pubmed, PsycInfo, SCOPUS, Sports Discus, Web of Science Core Collection, and Google Scholar were searched. Study selection and quality screening using the Cochrane risk of bias tool were conducted by two reviewers to mitigate bias. PRISMA guidelines were followed in conducting and reporting the review.

RESULTS

11 studies met inclusion criteria with a total sample of 2221 (≥70% female). Eight studies measured pain, six showing significant effectiveness (p=≤0.05), for lower limb osteoarthritis (OA), hand OA, and neck pain. Nine studies measured physical function, four showing significant effects, for lower limb OA and sarcopenia. Significant quality of life effects were found for restless leg syndrome compared to baseline.

CONCLUSION

Moderate evidence was found for pain effects, generalisable for OA based on sub-group analysis. Effective trials were mostly short-term using at minimum one 60-min group class, and an average of four 30-min home practice sessions weekly. Findings support the use of props and modifications to address age-related physical limitations. Yoga was well-received with good adherence, but effects on a par with other exercise. There was an absence of quality of life effects in short term. Mixed methods studies could lead to further insight into the qualitative aspects of yoga practice for older adults.

Increasing Trend of Yoga Practice Among U.S. Adults From 2002 to 2017

Introduction: Benefits, risks, and the increasing popularity of yoga use warrant assessing yoga practice prevalence and users' profiles. This study describes trends in yoga practice exclusively among American adults from 2002 to 2017, compares the profile of yoga users, and identifies factors related to yoga use over time. Materials and Methods: This study is a secondary analysis done in 2019 and 2020 using the National Health Interview Survey (NHIS) 2002, 2007, 2012, and 2017 data. Population weights were used to obtain statistically accurate estimates of yoga use prevalence for the U.S. population. Descriptive statistics were used to profile the sociodemographic and health-related characteristics of yoga users. Multivariable logistic regression was used to identify factors associated with yoga use in each cohort defined by the NHIS year. Results: Yoga practice prevalence nearly tripled from 5.1% in 2002 to 13.7% in 2017 (weighted estimate 10,386,456 and 32,761,194 American adults, respectively). Typical yoga users were young non-Hispanic single white female adults with bachelor or higher education and health insurance, and resided in the west region of the United States. Yoga use pattern change over time was significantly related to only younger age (p < 0.001) but not to other sociodemographic or health-related factors. Conclusions: Yoga has gained increasing popularity in the past two decades among American adults, with younger adults being the driving force. Yoga appears to be adopted for general well-being or prevention more than for specific disease treatment. Future research should evaluate how yoga can be effectively and safely integrated into preventive medicine strategies.

Brief Self-Compassion Training Alters Neural Responses to Evoked Pain for Chronic Low Back Pain: A Pilot Study

OBJECTIVE

Self-compassion meditation, which involves compassion toward the self in moments of suffering, shows promise for improving pain-related functioning, but its underlying mechanisms are unknown. This longitudinal, exploratory pilot study investigated the effects of a brief (eight contact hours, two weeks of home practice) self-compassion training on pain-related brain processing in chronic low back pain (cLBP).

METHODS

We evaluated functional magnetic resonance imaging (fMRI) response to evoked pressure pain and its anticipation during a self-compassionate state and compared altered brain responses following training with changes on self-reported measures of self-compassion (Self-Compassion Scale [SCS]), interoceptive awareness (Multidimensional Assessment of Interoceptive Awareness [MAIA]), and clinical pain intensity.

RESULTS

In a sample of participants with cLBP (N = 20 total, N = 14 with complete longitudinal data) who underwent self-compassion training, we observed reduced clinical pain intensity and disability (P < 0.01) and increased trait self-compassion and interoceptive awareness (all P < 0.05) following training. Evoked pressure pain response in the right temporo-parietal junction (TPJ) was reduced following training, and decreases were associated with reduced clinical pain intensity. Further, increased fMRI responses to pain anticipation were observed in the right dorsolateral prefrontal cortex (dlPFC) and ventral posterior cingulate cortex (vPCC), and these increases were associated with mean post-training changes in SCS scores and scores from the body listening subscale of the MAIA.

DISCUSSION

These findings, though exploratory and lacking comparison with a control condition, suggest that self-compassion training supports regulation of pain through the involvement of self-referential (vPCC), salience-processing (TPJ), and emotion regulatory (dlPFC) brain areas. The results also suggest that self-compassion could be an important target in the psychotherapeutic treatment of cLBP, although further studies using controlled experimental designs are needed to determine the specificity of these effects.

Crosswalking the Patient-Reported Outcomes Measurement Information System Physical Function, Pain Interference, and Pain Intensity Scores to the Roland-Morris Disability Questionnaire and the Oswestry Disability Index

OBJECTIVE

To link scores from 2 condition-specific measures for chronic low back pain (CLBP), the Oswestry Disability Index (ODI) and the Roland-Morris Disability Questionnaire (RMDQ), to Patient Reported Outcomes Measurement Information System (PROMIS) physical function, pain interference, and pain intensity scores.

DESIGN

Ordinary least squares regression analyses of existing data to link the PROMIS scores with the ODI and RMDQ.

SETTING

Not applicable.

PARTICIPANTS

Samples of adults with CLBP (N=2279) obtained from the Center for Excellence in Research for Complementary and Integrative Health (CERC) Study (n=1677), the Assessment of Chiropractic Treatment for Low Back Pain and Smoking Cessation in Military Active Duty Personnel (ACT) (n=384), and the pain subsample of the PROMIS 1 Wave 2 Pain and Depression study (PROMIS 1 W2) (n=218).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

PROMIS physical function, pain interference, and pain intensity (CERC, ACT, and PROMIS 1 W2), ODI (CERC and PROMIS 1 W2), and RMDQ (ACT and PROMIS 1 W2).

RESULTS

In predicting PROMIS scores, the ODI model R² values ranged from 0.26-0.56 and the RMDQ model R² values ranged from 0.13-0.50. ODI and RMDQ models were the least precise in predicting the PROMIS pain intensity score (R² value range, 0.13-0.41) relative to the other PROMIS scores. Models with the 3 PROMIS scores as predictors yielded R² values ranging from 0.64-0.68 and 0.46-0.58 for the ODI and RMDQ, respectively. Models using combined data from 2 studies (ie, PROMIS 1 W2 and ACT, or PROMIS 1 W2 and CERC) tended to be more precise than models using only a single study sample.

CONCLUSIONS

Model results reported here can be used to translate PROMIS physical function, pain interference, and pain intensity scores to and from the ODI and RMDQ. The empirical linkages can facilitate comparisons across CLBP interventions and broaden interpretation of study results.

A systematic review of yoga interventions for helping health professionals and students

Helping Health Professionals (HHP) and HHP students are among the highest risk occupational groups for compromised mental and physical health. There is a paucity of information regarding preventive interventions for mental and physical health in this group of healthcare providers.

OBJECTIVE

The objective of this review was to examine the effectiveness of yoga interventions for the prevention and reduction of mental and physical disorders among HHPs and HHP students.

DESIGN

An exhaustive systematic search was conducted in May 2020. Databases searched in the OVID interface included: MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily, Embase, and PsycINFO. EbscoHost databases searched included: CINAHL Plus with Full Text, SPORTDiscus with Full Text, Alt HealthWatch, Education Research Complete, SocINDEX with Full Text, ERIC, and Academic Search Complete. Scopus was also searched.

RESULTS

The search yielded 4,973 records, and after removal of duplicates 3197 records remained. Using inclusion and exclusion criteria, titles and abstracts were screened and full text articles (n = 82) were retrieved and screened. Twenty-five studies were identified for inclusion in this review. Most frequently reported findings of yoga interventions in this population included a reduction in stress, anxiety, depression, and musculoskeletal pain.

CONCLUSION

It is our conclusion that mental and physical benefits can be obtained through implementation of yoga interventions for HHPs and HHP students across a variety of settings and backgrounds. However, researchers would benefit from following recommended guidelines for the design and reporting of yoga interventions to improve study quality and rigour.

Benefits, barriers and determinants of practicing yoga: A cross sectional study from Kathmandu, Nepal

Background

It has been widely believed that practicing yoga helps to improve individuals’ mental and physical health. However, the proportion of people practicing yoga is not encouraging.

Objective

This study investigates the determinants, motivations, benefits and barriers to practicing yoga.

Material and methods

This study is based on a cross sectional survey of 875 individuals in a face-to-face interviews conducted from February to April 2019 in Kathmandu, Nepal. The interviews were conducted using a semi-structured questionnaire, and the statistical analysis of the collected data was done using SPSSV20.

Results

We find that females, older people, people with access to health education and internet, associated with social organization, and receiving yoga-related training are more likely to practice yoga. Major reported benefits of yoga include improvement in body flexibility and balance, a decrease in the level of stress, improvement in the quality of life, body weight maintenance, and improvement in immunity power.

Conclusion

Given that most respondents have been benefited from practicing yoga, we recommend people to incorporate yoga into their daily routine.

Effect of Rāja yoga Meditation on Psychological and Functional Outcomes in Spinal Cord Injury Patients

Background:

Spinal cord injury (SCI) is a debilitating disorder with dysfunction in daily activities and psychological consequences like anxiety as well as depression impacting the quality of life substantially. Existing treatments focus mainly on rehabilitation, symptom reduction, and secondary complications. However, psychological, social, and existential issues are least addressed in the prevailing models.

Aims:

To study the role of meditation in addressing psychological impairment and any resultant improvement in functional outcomes in SCI patients.

Methods:

Nonrandomized controlled study was conducted in a tertiary care center for SCI patients. Hospital inpatients were recruited into either experimental intervention group (add on easy rāja yoga with conventional rehabilitation-ER n = 50) or control intervention group (conventional rehabilitation alone-CR n = 50). Patients in the ER group received easy rāja yoga for 1 month, along with conventional rehabilitation and the CR group patients received only conventional rehabilitation. All the subjects were assessed for psychological (perceived stress scale [PSS], Hospital Anxiety and Depression Scale [HADS]) and functional impairment (spinal cord independence measure (SCIM), numeric pain rating (NPR) and WHO quality of life-BRIEF (WHOQOLBREF)] at baseline and after 1 month.

Results:

After 1 month of add-on easy rāja yoga, there was significant decrease in the scores of HADS (F[1,88] = 272.92, P < 0.001), PSS (F[1,88] = 274.41, P < 0.001) and NPR (F[1,88] = 60.60, P < 0.001) and significant increase in the scores of WHOQOLBREF (F[1,88] = 349.94, P < 0.001) and SCIM (F[1,88] = 29.09, P < 0.001) in the ER group compared to CR group in analysis of covariance.

Conclusion:

One-month add-on easy rāja yoga improves psychological and functional outcomes (HADS, PSS, NPR, WHOQOLBREF and SCIM) in patients with SCI. Future studies with robust designs are needed to validate the results.

Which Chronic Low Back Pain Patients Respond Favorably to Yoga, Physical Therapy, and a Self-care Book? Responder Analyses from a Randomized Controlled Trial

PURPOSE

To identify baseline characteristics of adults with chronic low back pain (cLBP) that predict response (i.e., a clinically important improvement) and/or modify treatment effect across three nonpharmacologic interventions.

DESIGN

Secondary analysis of a randomized controlled trial.

SETTING

Academic safety net hospital and seven federally qualified community health centers.

SUBJECTS

Adults with cLBP (N = 299).

METHODS

We report patient characteristics that were predictors of response and/or modified treatment effect across three 12-week treatments: yoga, physical therapy [PT], and a self-care book. Using preselected characteristics, we used logistic regression to identify predictors of "response," defined as a ≥30% improvement in the Roland Morris Disability Questionnaire. Then, using "response" as our outcome, we identified baseline characteristics that were treatment effect modifiers by testing for statistical interaction (P < 0.05) across two comparisons: 1) yoga-or-PT vs self-care and 2) yoga vs PT.

RESULTS

Overall, 39% (116/299) of participants were responders, with more responders in the yoga-or-PT group (42%) than the self-care (23%) group. There was no difference in proportion responding to yoga (48%) vs PT (37%, odds ratio [OR] = 1.5, 95% confidence interval = 0.88 - 2.6). Predictors of response included having more than a high school education, a higher income, employment, few depressive symptoms, lower perceived stress, few work-related fear avoidance beliefs, high pain self-efficacy, and being a nonsmoker. Effect modifiers included use of pain medication and fear avoidance beliefs related to physical activity (both P = 0.02 for interaction). When comparing yoga or PT with self-care, a greater proportion were responders among those using pain meds (OR = 5.3), which differed from those not taking pain meds (OR = 0.94) at baseline. We also found greater treatment response among those with lower (OR = 7.0), but not high (OR = 1.3), fear avoidance beliefs around physical activity.

CONCLUSIONS

Our findings revealed important subgroups for whom referral to yoga or PT may improve cLBP outcomes.

Auricular Point Acupressure Smartphone Application to Manage Chronic Musculoskeletal Pain: A Longitudinal, One-Group, Open Pilot Trial

BACKGROUND

Chronic musculoskeletal pain (CMP) is the most common self-reported chronic pain condition. Current treatment for CMP is limited.

METHODS

This was a two-phase study. In Phase 1, three auricular point acupressure (APA)-naïve participants were recruited to explore their experiences of APA and a smartphone app was developed based on their feedback. In Phase 2, a prospective longitudinal study was used to examine the effectiveness of the smartphone app to self-manage CMP.

RESULTS

Phase 1 resulted in the successful development of the APA smartphone app. In Phase 2, after four weeks of APA, participants reported reduced pain intensity (30%), pain interference (35%), and disability (40%), as well as improved physical function (47%). The mean score for the participants' perception of treatment efficacy was 4.94 (SD = 2.08, scale of 0-7) indicating that approximately 70% of participants rated global improvements with noticeable changes. The majority (88%, n = 22) of the participants were satisfied with the treatment: 32% [8] were very satisfied and 56% [n = 14] were somewhat satisfied. The average frequency of pressing APA seeds per day was 2.93 times (SD = 2.27, range 0-10) and 1.60 minutes per time (SD = 2.64, range 0-10); the participants were able to adhere to the suggested pressing time per day, although they only pressed the ear points about 53% of the suggested time.

CONCLUSION

It is feasible for individuals to learn APA from the smartphone app and successfully self-administer APA to manage their pain. Participants found the app useful and were satisfied with the information provided through the app.

Yoga Improves Balance and Low-Back Pain, but Not Anxiety, in People with Parkinson's Disease

Individuals with Parkinson's disease (PD) experience postural instability, low-back pain (LBP), and anxiety. These symptoms increase the risk of falls and decrease quality of life. Research shows yoga improves balance and decreases LBP and anxiety in healthy adults, but its effects in PD are poorly understood. All participants were part of a larger intervention study. Participants received pretest and posttest evaluations, including the Balance Evaluation Systems Test (BESTest), Beck Anxiety Inventory (BAI), and Revised Oswestry Disability Index (ROSW). Total scores for each measure, as well as individual balance system section scores from the BESTest (biomechanical constraints, stability limits/verticality, transitions/anticipatory, reactive, sensory orientation, and stability in gait) were compared within groups pre- to posttest. Participants in the yoga group (n = 13) completed a twice-weekly 12-week yoga interve n t i o n , whereas controls (n = 13) continued their usual routines for 12 weeks. Both the yoga (Z = -3.20, p = 0.001) and control (Z = -2.10, p = 0.040) groups improved on the BESTest total score. The control group showed no changes in individual balance systems, whereas the yoga group improved in stability limits/verticality (Z = -2.3, p = 0.020), transitions/ anticipatory (Z = -2.50, p = 0.010), reactive (Z = -2.70, p = 0.008), and sensory orientation (Z = -2.30, p = 0.020). ROSW decreased in the yoga group only (Z = -2.10, p = 0.030). BAI did not change in either group. Yoga is a nonpharmacological intervention that can improve balance and LBP in people with PD. This study demonstrated that yoga is feasible for people with PD, and participants reported high levels of enjoyment and intent to practice yoga after the study.

If we offer, will they come: Perceptions of yoga among Hispanics

OBJECTIVE

Yoga is underutilized by the Hispanics. This study examined perceptions of benefits and barriers to yoga among Hispanic adults, to provide information that may increase their participation in this practice.

SETTING

Participants were recruited from a Community Center serving low-income Hispanics.

DESIGN

Self-administered cross-sectional questionnaires assessing benefits and barriers to yoga were conducted in Spanish and English. Fisher's exact test was used to examine perceptions of yoga by gender, age, and prior experience.

RESULTS

Participants (ages 18-85, 65 % women, n = 121) reported several benefits to yoga. Hispanic women, individuals 65 y or older, and those with prior experience, perceived more benefits. Barriers to yoga also differed by demographics. Men reported that time and the perception that they would have to do unrealistic pretzel-like poses as deterrents to yoga practice; younger individuals perceived yoga to be boring, and those with no experience perceived lack of flexibility and feeling like an outsider in class, as barriers to yoga. The most common barrier, across subgroups, was the cost associated with yoga practice. The majority of participants reported being willing to attend yoga classes if offered at a low cost.

CONCLUSION

Perceived barriers related to yoga reflect a lack of knowledge about yoga and what it entails and the cost of classes. Despite these barriers, Hispanic adults from a low-income population said they would be willing to attend yoga classes if offered at a low cost. Understanding and addressing these barriers can help researchers and health practitioners improve diversity in yoga classes and research.

Yoga not a (physical) culture for men? Understanding the barriers for yoga participation among men

Yoga offers an integrated approach to health and well-being that could potentially benefit men. This qualitative descriptive study examined men's perceptions of yoga, and identified barriers and possible facilitators for participation. Twenty-one non-yoga participant men, 18-60 years old, and living in Queensland, Australia, were interviewed. Two major barriers were identified using thematic analysis: (1) preference for other forms of physical activity, and (2) gender-related perceptions and pressures (i.e., perception of yoga as feminine, and presence of "bloke" culture and masculine ideals in society). Potential facilitators included: (1) acceptability of yoga among men, (2) providing brief information sessions, and (3) men-only classes. The non-competitive nature of yoga, in addition to being predominantly undertaken by women, makes it less appealing for men living in Australia. These barriers need to be considered if yoga is to be promoted as an option for men, particularly those not drawn to traditional sports or exercise.

Group Acupuncture Therapy With Yoga Therapy for Chronic Neck, Low Back, and Osteoarthritis Pain in Safety Net Setting for an Underserved Population: Design and Rationale for a Feasibility Pilot

Chronic pain is prevalent in the United States, with impact on physical and psychological functioning as well as lost work productivity. Minority and lower socioeconomic populations have increased prevalence of chronic pain with less access to pain care, poorer outcomes, and higher risk of fatal opioid overdose. Acupuncture therapy is effective in treating chronic pain conditions including chronic low back pain, neck pain, shoulder pain, and knee pain from osteoarthritis. Acupuncture therapy, including group acupuncture, is feasible and effective, and specifically so for underserved and diverse populations at risk for health outcome disparities. Acupuncture therapy also encourages patient engagement and activation. As chronic pain improves, there is a natural progression to want and need to increase activity and movement recovery. Diverse movement approaches are important for improving range of motion, maintaining gains, strengthening, and promoting patient engagement and activation. Yoga therapy is an active therapy with proven benefit in musculoskeletal pain disorders and pain associated disability. The aim of this quasi-experimental pilot feasibility trial is to test the bundling of these 2 effective care options for chronic pain, to inform both the design for a larger randomized pragmatic effectiveness trial as well as implementation strategies across underserved settings.

Which specific modes of exercise training are most effective for treating low back pain? Network meta-analysis

OBJECTIVE

Examine the effectiveness of specific modes of exercise training in non-specific chronic low back pain (NSCLBP).

DESIGN

Network meta-analysis (NMA).

DATA SOURCES

MEDLINE, CINAHL, SPORTDiscus, EMBASE, CENTRAL.

ELIGIBILITY CRITERIA

Exercise training randomised controlled/clinical trials in adults with NSCLBP.

RESULTS

Among 9543 records, 89 studies (patients=5578) were eligible for qualitative synthesis and 70 (pain), 63 (physical function), 16 (mental health) and 4 (trunk muscle strength) for NMA. The NMA consistency model revealed that the following exercise training modalities had the highest probability (surface under the cumulative ranking (SUCRA)) of being best when compared with true control: Pilates for pain (SUCRA=100%; pooled standardised mean difference (95% CI): -1.86 (-2.54 to -1.19)), resistance (SUCRA=80%; -1.14 (-1.71 to -0.56)) and stabilisation/motor control (SUCRA=80%; -1.13 (-1.53 to -0.74)) for physical function and resistance (SUCRA=80%; -1.26 (-2.10 to -0.41)) and aerobic (SUCRA=80%; -1.18 (-2.20 to -0.15)) for mental health. True control was most likely (SUCRA≤10%) to be the worst treatment for all outcomes, followed by therapist hands-off control for pain (SUCRA=10%; 0.09 (-0.71 to 0.89)) and physical function (SUCRA=20%; -0.31 (-0.94 to 0.32)) and therapist hands-on control for mental health (SUCRA=20%; -0.31 (-1.31 to 0.70)). Stretching and McKenzie exercise effect sizes did not differ to true control for pain or function (p>0.095; SUCRA<40%). NMA was not possible for trunk muscle endurance or analgesic medication. The quality of the synthesised evidence was low according to Grading of Recommendations Assessment, Development and Evaluation criteria.

SUMMARY/CONCLUSION

There is low quality evidence that Pilates, stabilisation/motor control, resistance training and aerobic exercise training are the most effective treatments, pending outcome of interest, for adults with NSCLBP. Exercise training may also be more effective than therapist hands-on treatment. Heterogeneity among studies and the fact that there are few studies with low risk of bias are both limitations.

Yoga for warriors: An intervention for veterans with comorbid chronic pain and PTSD

OBJECTIVE

Comorbid chronic pain and posttraumatic stress disorder (PTSD) is common in veterans; this comorbidity is associated with increased severity and poorer prognosis when compared to each outcome alone. Yoga has been shown to be effective for chronic pain and promising for PTSD, but yoga for comorbid pain and PTSD has not been examined. This article offers empirical support for a yoga intervention for comorbid chronic pain and PTSD in a veteran population.

METHOD

Results are presented from a 4-year pilot yoga intervention for comorbid chronic pain and PTSD at a large, urban Veterans Affairs Medical Center. Based on the fear avoidance model of pain, the intervention used a cross-sectional, open-trial design with pre- and postmeasures. T test analyses were conducted on program completers (N = 49; out of 87 initially enrolled, 44% attrition rate), who were primarily African American (69%) and male (61%) and had a mean age of 51.41 years (SD = 11.32).

RESULTS

Results indicated trend-level reductions in overall PTSD symptoms, as measured by the PTSD Checklist for DSM-5 (p = .02, d = 0.38) and in symptom cluster scores of negative alterations of cognitions and mood (p = .03, d = 0.36) and arousal and reactivity (p = .03, d = 0.35). Veterans reported significant improvement in ability to participate in social activities (p < .001, d = 0.44) and significant reductions in kinesiophobia (fear of movement or physical activity; p < .001, d = 0.85). On a satisfaction measure with a range of 1 (quite dissatisfied) to 4 (extremely satisfied), the mean rating was 3.74 (SD = 0.33).

CONCLUSION

Yoga is a feasible and effective intervention for veterans with comorbid chronic pain and PTSD. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Yoga v. health education for attentional processes relevant to major depressive disorder

Objectives

Research has shown that yoga may be an effective adjunctive treatment for persistent depression, the benefits of which may accumulate over time. The objectives of this study were to evaluate the following in a sample of persistently depressed individuals: whether yoga increases mindfulness and whether yoga attenuates rumination. Rumination and mindfulness both represent attentional processes relevant for onset and maintenance of depressive episodes.

Methods

One-hundred-ten individuals who were persistently depressed despite ongoing use of pharmacological treatment were recruited into an RCT comparing yoga with a health education class. Mindfulness and rumination were assessed at baseline and across 3 time points during the ten-week intervention.

Results

Findings demonstrate that, compared to health education, yoga was associated with higher mean levels of the observe facet of mindfulness relative to the control group during the intervention period (p =.004, d =0.38), and that yoga was associated with a faster rate of increase in levels of acting with awareness over the intervention period (p= .03, f² =0.027). There were no differences between intervention groups with respect to rumination.

Conclusions

Results suggest a small effect of yoga on components of mindfulness during a 10-week intervention period. Previous research suggests that continued assessment after the initial 10 weeks may reveal continued improvement. Future research may also examine moderators of the impact of yoga on mindfulness and rumination, including clinical factors such as depression severity or depression chronicity, or demographic factors such as age.

Feasibility of a yoga intervention to decrease pain in older women: a randomized controlled pilot study

BACKGROUND

A significant proportion of older women suffer from chronic pain, which can decrease quality of life. The objective of this pilot randomized study was to evaluate the feasibility of a flow-restorative yoga intervention designed to decrease pain and related outcomes among women aged 60 or older.

METHODS

Flow-restorative yoga classes were held twice weekly for 1 hour and led by a certified yoga instructor. Participants randomized to the intervention group attended the yoga classes for 12 weeks and received supplemental materials for at-home practice. Those randomized to the control group were asked to maintain their normal daily routine. Feasibility was evaluated using recruitment and retention rates, class and home practice adherence rates, and participant satisfaction surveys. Outcome measures (self-reported pain, inflammatory markers, functional fitness, quality of life, resilience, and self-reported physical activity) were assessed at baseline and post-intervention. Paired t-tests or Wilcoxon signed-rank tests were used to examine changes in outcome measures within treatment groups.

RESULTS

Thirty-eight participants were recruited and randomized. Participants were primarily white, college-educated, and higher functioning, despite experiencing various forms of chronic pain. Attendance and retention rates were high (91 and 97%, respectively) and the majority of participants were satisfied with the yoga program (89%) and would recommend it to others (87%). Intervention participants also experienced reductions in pain interference and improvements in energy and social functioning.

CONCLUSIONS

This pilot study provides essential data to inform a full scale randomized trial of flow-restorative yoga for older women with chronic pain. Future studies should emphasize strategies to recruit a more diverse study population, particularly older women at higher risk of disability and functional decline.

A protocol for chronic pain outcome measurement enhancement by linking PROMIS-29 scale to legacy measures and improving chronic pain stratification

BACKGROUND

Substantial investment has gone into research on the efficacy and effectiveness of pharmaceutical and nonpharmacologic interventions for chronic pain. However, synthesizing this extensive literature is challenging because of differences in the outcome measures used in studies of similar or competing interventions. The absence of a common metric makes it difficult to replicate findings, pool data from multiple studies, resolve conflicting conclusions, or reach consensus when interpreting findings.

METHODS

This study has a seven-member Advisory Council of chronic pain experts. Preliminary analyses will be performed on data from several large existing datasets; intermediate analyses will be performed using primary data collected from Amazon's Mechanical Turk (MTurk); and cross-validation will use primary data collected from a nationally-representative, probability-based panel. Target sample size for both primary datasets is 1500. The three study aims are as follows: Aim 1 will develop and evaluate links between the 29-item Patient-Reported Outcomes Measurement Information System (PROMIS®-29) and legacy measures used for chronic pain such as the Roland-Morris Disability Questionnaire (RMDQ) and the Oswestry Disability Index (ODI). We will assess the best method of score linking and create crosswalk tables. Aim 2 will evaluate and refine the Impact Stratification Score (ISS) based on 9 PROMIS-29 items and proposed by the NIH Research Task Force on chronic low back pain. We will evaluate the ISS in terms of other indicators of condition severity and patient prognosis and outcomes and identify cut-points to stratify chronic pain patients into subgroups. Aim 3 will evaluate the strengths and limitations of MTurk as a data collection platform for estimating chronic pain by comparing its data to other data sources.

DISCUSSION

The accomplishment of Aims 1 and 2 will allow direct comparison of results across past and future studies of chronic pain. These comparisons will help us to understand different results from seemingly similar studies, and to determine the relative effectiveness of all pharmaceutical and nonpharmacologic interventions for chronic pain across different trials. Aim 3 findings will provide valuable information to researchers about the pros and cons of using the MTurk platform for research-based data collection.

Are screening by yoga instructors and their practice patterns important to prevent injuries in yoga clients?

BACKGROUND AND PURPOSE

Little information exists regarding the association of yoga-related injuries with yoga instructor (YI) practice patterns. Therefore, this cross-sectional survey examined the screening and practice characteristics of YI and its relationship with yoga-related injuries.

METHODS AND MATERIALS

YI from Northeastern US completed a customized web-based 57-item questionnaire.

RESULTS

The response rate of our questionnaire was 46%. In this study, only 8.8% of the YI reported physical performance screening and 33.7% of the participants did medical screenings with their clients. A binomial logistic regression analysis with the above variables revealed that adherence to training by YI (p = 0.031) and the use of Sun Salutations (p = 0.002) predicted lower yoga-related injuries in clients reported by YI.

CONCLUSIONS

Reduction in client yoga-related injuries was predicted by YI adhering to their training and performing Sun Salutations in their classes.

Yoga compared to non-exercise or physical therapy exercise on pain, disability, and quality of life for patients with chronic low back pain: A systematic review and meta-analysis of randomized controlled trials

Background

Chronic low back pain (CLBP) is a common and often disabling musculoskeletal condition. Yoga has been proven to be an effective therapy for chronic low back pain. However, there are still controversies about the effects of yoga at different follow-up periods and compared with other physical therapy exercises.

Objective

To critically compare the effects of yoga for patients with chronic low back pain on pain, disability, quality of life with non-exercise (e.g. usual care, education), physical therapy exercise.

Methods

This study was registered in PROSPERO, and the registration number was CRD42020159865. Randomized controlled trials (RCTs) of online databases included PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase which evaluated effects of yoga for patients with chronic low back pain on pain, disability, and quality of life were searched from inception time to November 1, 2019. Studies were eligible if they assessed at least one important outcome, namely pain, back-specific disability, quality of life. The Cochrane risk of bias tool was used to assess the methodological quality of included randomized controlled trials. The continuous outcomes were analyzed by calculating the mean difference (MD) or standardized mean difference (SMD) with 95% confidence intervals (CI) according to whether combining outcomes measured on different scales or not.

Results

A total of 18 randomized controlled trials were included in this meta-analysis. Yoga could significantly reduce pain at 4 to 8 weeks (MD = -0.83, 95% CI = -1.19 to -0.48, p<0.00001, I² = 0%), 3 months (MD = -0.43, 95% CI = -0.64 to -0.23, p<0.0001, I² = 0%), 6 to 7 months (MD = -0.56, 95% CI = -1.02 to -0.11, p = 0.02, I² = 50%), and was not significant in 12 months (MD = -0.52, 95% CI = -1.64 to 0.59, p = 0.36, I² = 87%) compared with non-exercise. Yoga was better than non-exercise on disability at 4 to 8 weeks (SMD = -0.30, 95% CI = -0.51 to -0.10, p = 0.003, I² = 0%), 3 months (SMD = -0.31, 95% CI = -0.45 to -0.18, p<0.00001, I² = 30%), 6 months (SMD = -0.38, 95% CI = -0.53 to -0.23, p<0.00001, I² = 0%), 12 months (SMD = -0.33, 95% CI = -0.54 to -0.12, p = 0.002, I² = 9%). There was no significant difference on pain, disability compared with physical therapy exercise group. Furthermore, it suggested that there was a non-significant difference on physical and mental quality of life between yoga and any other interventions.

Conclusion

This meta-analysis provided evidence from very low to moderate investigating the effectiveness of yoga for chronic low back pain patients at different time points. Yoga might decrease pain from short term to intermediate term and improve functional disability status from short term to long term compared with non-exercise (e.g. usual care, education). Yoga had the same effect on pain and disability as any other exercise or physical therapy. Yoga might not improve the physical and mental quality of life based on the result of a merging.

Exercise, brain plasticity, and depression

Depression is a common mental disorder characterized by high incidence, high disability, and high fatality, causing great burden to the society, families, and individuals. The changes in brain plasticity may be a main reason for depression. Recent studies have shown that exercise plays a positive role in depression, but systematic and comprehensive studies are lacking on brain plasticity changes in depression. To further understand the antidepressive effect of exercise and the changes in brain plasticity, we retrieved related literatures using key words "depression," "depressive disorder," "exercise," "brain plasticity," "brain structure," and "brain function" from the database of Web of Science, PubMed, EBSCO host, and CNKI, hoping to provide evidence for exercise in preventing and treating depression. Increase in exercise has been found negatively correlated with the risk of depression. Randomized controlled experiments have shown that aerobic exercise, resistance exercise, and mind-body exercise can improve depressive symptoms and levels. The intensity and long-term effect of exercise are now topical research issues. Exercise has been proven to reshape the brain structure of depression patients, activate the function of related brain areas, promote behavioral adaptation changes, and maintain the integrity of hippocampal and white matter volume, thus improving the brain neuroprocessing and delaying cognitive degradation in depression patients. Future studies are urgently needed to establish accurate exercise prescriptions for improving depressive symptoms, and studies on different depressive populations and studies using multimodal brain imaging combined with multiple analytical methods are also needed.

Yoga and Tai Chi: a mind-body approach in managing respiratory symptoms in obstructive lung diseases

PURPOSE OF REVIEW

Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation because of airway and/or alveolar abnormalities. Symptoms include dyspnea, cough, chronic sputum production. As the third-ranked cause of death as well as disability-adjusted life years (DALYs), it poses a significant burden on patients, families, healthcare system and society. Regular physical activity is linked to decrease in morbidity and mortality associated with COPD, but implementation remains challenging. There is a need for community-based interventions that promote physical activity. Yoga and Tai Chi are widely available in the community and have been shown to be beneficial in patients with COPD as well as many of the co-morbid conditions associated with COPD.

RECENT FINDINGS

Yoga and Tai Chi have been found to be more effective than usual care in COPD with clinically meaningful improvements in 6-min walk distance (6MWD), forced expiratory volume in 1 s (FEV1), and health-related quality of life (HRQoL). They have also been found to be comparable to pulmonary rehabilitation interventions.

SUMMARY

Yoga and Tai Chi provide community-based options for patients with COPD to improve their physical activity, quality of life, and pulmonary function.

Comparative efficacy of different exercise interventions in chronic non-specific low back pain: protocol of a systematic review and network meta-analysis

INTRODUCTION

Chronic non-specific low back pain is a major public health problem. Evidence supports the effectiveness of exercise as an intervention. Due to a paucity of direct comparisons of different exercise categories, medical guidelines were unable to make specific recommendations regarding the type of exercise working best in improving chronic low back pain. This network meta-analysis (NMA) of randomised controlled trials aims to investigate the comparative efficacy of different exercise interventions in patients with chronic non-specific low back pain.

METHODS AND ANALYSIS

MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, SPORTDiscus, Clinicaltrials.gov and the WHO International Clinical Trials Registry Platform search portal were searched on November 2019 and without language restrictions. The search will be updated after data analysis. Studies on adults with non-specific low back pain of at least 12 weeks duration comparing exercise to either no specific intervention (ie, no treatment, wait-list or usual care at the treating physician's discretion) and/or functionally inert interventions (ie, sham or attention control interventions) will be eligible. Pain intensity and back-specific disability are defined as primary outcomes. Secondary outcomes will include health-related physical and mental quality of life, work disability, frequency of analgesic use and adverse events. All outcomes will be analysed short-term, intermediate-term and long-term. Data will be extracted independently by two review authors. Risk of bias will be assessed using the recommendations by the Cochrane Back and Neck Group and be based on an adaptation of the Cochrane Risk of Bias tool.

ETHICS AND DISSEMINATION

This NMA will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses_NMA checklist. The results will be presented in peer-reviewed journals, implemented in existing national and international guidelines and will be presented to health care providers and decision makers. The planned completion date of the study is 1 July 2021.

Yoga and relaxation for promoting public health: A review of the practice and supportive research

The purpose of this review is to present yoga as an important tool for both disease prevention and health care. Yoga involves a holistic approach that lacks the mechanistic fragmentation of the impact on individual organs and body systems, which arises from much of the specialization found in modern medicine. Lifestyle diseases are increasingly a problem. The incidence of diabetes, hypertension, atherosclerosis, cancer, mental illness and obesity is increasing worldwide. This is true even of countries that, until recently, followed a traditional way of life. Technology, the pace of life, stress, and reduced physical activity serve to degrade the general level of health in societies across the globe. In Western societies, these factors have raised the demand for preventive and therapeutic antidotes, leading Westerners to turn to traditional yoga, which is, however, often modified to the point of distorting its essence. In its original nature yoga is a non-religious, psychosomatic system based on natural laws, inspired by science to act on the body in a way that is integrated into the natural world. The system of Ayurvedic medicine works in parallel with yoga, aiming at the same holistic effect. Both it and the various elements of yoga, in particular asanas (postures), are the means of effecting beneficial changes in psychosomatic functioning. Yoga itself relaxes and strengthens physical movement, focusing particular attention on the mobility of the spine. It is also the perfect medium for achieving mental balance. These properties of yoga have made it useful in the treatment of cancer and other modern diseases, in slowing the body’s aging process, and in achieving general welfare and well-being. More intense forms of yoga practice, such as the ancient method of fitness training called Suryanamaskar, have demonstrated their effectiveness in preventing and treating cardiovascular diseases, respiratory ailments and other conditions.

Mindful2Work the next steps: Effectiveness of a program combining physical exercise, yoga and mindfulness, adding a wait-list period, measurements up to one year later and qualitative interviews

BACKGROUND

Mindful2Work is a 6-week program combining physical activity, yoga and mindfulness meditations, targeting (work-related) stress complaints from a body-mind perspective.

MATERIALS AND METHODS

We combined a top-down approach (researcher-driven outcome measures) with a bottom-up approach (personal goals and interview data) to investigate the effects on 98 employees with at least moderate (work-related) stress. Effects on personal goals, well-being (stress, anxiety, depression, sleep, affect, happiness), functioning at work (dropout, mental and physical workability, work satisfaction), and training-specific aspects (mindful awareness, self-compassion, emotion regulation strategies) were assessed.

RESULTS

Nearly all measures showed no change during the wait-list period, with only negative affect and physical workability showing small statistically significant improvements. Medium to large effect size improvements directly after training and at all follow-ups were found on primary outcomes stress (0.62-1.17), and risk for dropout from work (0.55-1.00), and largest effects occurred on personal goals (0.98-1.46). Improvements in well-being and functioning at work were medium directly after training, and at follow-up 1 (six weeks later) and 2 (six months later), and large at follow-up 3 (one year later). The training-specific measures showed small to medium effects after training and at follow-up 1. Further, from the interviews (n = 9), two main categories of effects emerged: well-being and acquired insights.

CONCLUSION

Mindful2Work showed substantial and long-lasting improvements according to researcher-driven measures as well as participants' own reports.

Meta-Analysis of Integrated Therapeutic Methods in Noninvasive Lower Back Pain Therapy (LBP): The Role of Interdisciplinary Functional Diagnostics

Introduction. Lower back pain (LBP) is almost a problem of civilizations. Quite often, it is a consequence of many years of disturbed distribution of tension within the human body caused by local conditions (injuries, hernias, stenoses, spondylolisthesis, cancer, etc.), global factors (postural defects, structural integration disorders, lifestyle, type of activity, etc.), or systemic diseases (connective tissue, inflammation, tumours, abdominal aneurysm, and kidney diseases, including urolithiasis, endometriosis, and prostatitis). Therefore, LBP rehabilitation requires the use of integrated therapeutic methods, combining the competences of interdisciplinary teams, both in the process of diagnosis and treatment. Aim of the Study. Given the above, the authors of the article conducted meta-analysis of the literature in terms of integrated therapeutic methods, indicating the techniques focused on a holistic approach to the patient. The aim of the article is to provide the reader with comprehensive knowledge about treating LBP using noninterventional methods. Material and Methods. An extensive search for the materials was conducted online using PubMed, the Cochrane database, and Embase. The most common noninterventional methods have been described, as well as the most relevantly updated and previously referenced treatment of LBP. The authors also proposed noninvasive (measurable) diagnostic procedures for the functional assessment of the musculoskeletal system, including initial, systematic, and cross-sectional control. All figures and images have been prepared by the authors and are their property.

Results

This review article goes beyond combining a detailed description of each procedure with full references, as well as a comprehensive discussion of this very complex and troublesome problem.

Conclusions

Lower back pain is a serious health problem, and this review article will help educate physicians and physiotherapists dealing with LBP in the options of evidence-based treatment. Ultimately, the article introduces and postulates the need to systematize therapeutic procedures in LBP therapy, with a long-term perspective.

Neck Pain and Lower Back Pain

Neck pain is the fourth leading cause of disability. Acute neck pain largely resolves within 2 months. History and physical examination play a key role in ruling out some of the more serious causes for neck pain. The evidence for pharmacologic interventions for acute and chronic musculoskeletal neck pain is limited. Lower back pain is the leading cause of disability and productivity loss. Consultation with a physical medicine and rehabilitation spine specialist within 48 hours for acute pain and within 10 days for all patients with lower back pain may significantly decrease rate of surgical interventions and increase patient satisfaction.

Effect of complementary and alternative medicine interventions on cancer related pain among breast cancer patients: A systematic review

OBJECTIVE

This systematic review aimed to evaluate the efficacy of CAM interventions for cancer-related pain in breast cancer patients.

METHODS

Databases (PubMed, Scopus, Web of Science, and EMBASE) were searched from January 1, 2000, up to April 31, 2019, using the keywords: Complementary and alternative medicine therapies and cancer related pain. Standard tools were used to evaluate the quality of the studies included.

RESULTS

Of the 3742 articles found, 46 articles comprising 3685 participants entered the final phase. Our results indicate that interventions including acupuncture/acupressure, tai chi/qi gong, hypnosis, meditation, music therapy, yoga, massage, reflexology, and Reiki improve cancer-related pain in breast cancer patients. However, aromatherapy had no effect on the same.

CONCLUSIONS

Despite the positive effect of various CAM interventions in reducing cancer-related pain, necessary precautions should be adopted to use them alongside other treatments to control cancer pain in the clinical setting.

Yoga practice in the UK: a cross-sectional survey of motivation, health benefits and behaviours

OBJECTIVES

Despite the popularity of yoga and evidence of its positive effects on physical and mental health, little is known about yoga practice in the UK. This study investigated the characteristics of people who practise yoga, reasons for initiating and maintaining practice, and perceived impact of yoga on health and well-being.

DESIGN, SETTING AND PARTICIPANTS

A cross-sectional online anonymous survey distributed through UK-based yoga organisations, studios and events, through email invites and flyers. 2434 yoga practitioners completed the survey, including 903 yoga teachers: 87% were women, 91% white and 71% degree educated; mean age was 48.7 years.

MAIN OUTCOME MEASURES

Perceived impact of yoga on health conditions, health outcomes and injuries. Relationships between yoga practice and measures of health, lifestyle, stress and well-being.

RESULTS

In comparison with national population norms, participants reported significantly higher well-being but also higher anxiety; lower perceived stress, body mass index and incidence of obesity, and higher rates of positive health behaviours. 47% reported changing their motivations to practise yoga, with general wellness and fitness key to initial uptake, and stress management and spirituality important to current practice. 16% of participants reported starting yoga to manage a physical or mental health condition. Respondents reported the value of yoga for a wide range of health conditions, most notably for musculoskeletal and mental health conditions. 20.7% reported at least one yoga-related injury over their lifetime. Controlling for demographic factors, frequency of yoga practice accounted for small but significant variance in health-related regression models (p<0.001).

CONCLUSION

The findings of this first detailed UK survey were consistent with surveys in other Western countries. Yoga was perceived to have a positive impact on physical and mental health conditions and was linked to positive health behaviours. Further investigation of yoga's role in self-care could inform health-related challenges faced by many countries.

Yoga, Physical Therapy, and Back Pain Education for Sleep Quality in Low-Income Racially Diverse Adults with Chronic Low Back Pain: a Secondary Analysis of a Randomized Controlled Trial

BACKGROUND

Poor sleep is common among adults with chronic low back pain (cLBP), but the influence of cLBP treatments, such as yoga and physical therapy (PT), on sleep quality is under studied.

OBJECTIVE

Evaluate the effectiveness of yoga and PT for improving sleep quality in adults with cLBP.

DESIGN

Secondary analysis of a randomized controlled trial.

SETTING

Academic safety-net hospital and 7 affiliated community health centers.

PARTICIPANTS

A total of 320 adults with cLBP.

INTERVENTION

Twelve weekly yoga classes, 1-on-1 PT sessions, or an educational book.

MAIN MEASURES

Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) global score (0-21) at baseline, 12 weeks, and 52 weeks. Additionally, we also evaluated how the proportion of participants who achieved a clinically meaningful improvement in sleep quality (> 3-point reduction in PSQI) at 12 weeks varied by changes in pain and physical function at 6 weeks.

KEY RESULTS

Among participants (mean age = 46.0, 64% female, 82% non-white), nearly all (92%) reported poor sleep quality (PSQI > 5) at baseline. At 12 weeks, modest improvements in sleep quality were observed among the yoga (PSQI mean difference [MD] = - 1.19, 95% confidence interval [CI] - 1.82, - 0.55) and PT (PSQI MD = - 0.91, 95% CI - 1.61, - 0.20) groups. Participants who reported a ≥ 30% improvement in pain or physical function at 6 weeks, compared with those who improved < 10%, were more likely to be a sleep quality responder at 12 weeks (odds ratio [OR] = 3.51, 95% CI 1.73, 7.11 and OR = 2.16, 95% CI 1.18, 3.95, respectively). Results were similar at 52 weeks.

CONCLUSION

In a sample of adults with cLBP, virtually all with poor sleep quality prior to intervention, modest but statistically significant improvements in sleep quality were observed with both yoga and PT. Irrespective of treatment, clinically important sleep improvements at the end of the intervention were associated with mid-intervention pain and physical function improvements.

Cardiovascular phenotyping for personalized lifestyle treatments of chronic abdominal pain in Irritable Bowel Syndrome: A randomized pilot study

BACKGROUND

Different physical exercise interventions for pain and other related symptoms largely follow non-personalized guidelines and show a high degree of variability in outcome. These interventions are considered to have different pathways toward improvement in autonomic regulation of energy metabolism. The current pilot study was conducted to assess the predictive value of individual cardiovascular (CV) activity markers at rest to predict clinical outcomes for two popular exercise-based interventions (walking and yoga) in patients with Irritable Bowel Syndrome (IBS).

METHODS

Twenty-seven adult participants with IBS were randomly assigned to a 16-biweekly Iyengar yoga or walking program. They completed pre- and post-treatment assessments on IBS symptom severity, affective and somatic complaints, and various measures of resting autonomic function including blood pressure (BP), heart rate and its variability, baroreceptor sensitivity (BRS) to activations and inhibitions with gains of brady- and tachycardiac baro-responses, and BP start points for these spontaneous baroreflexes.

RESULTS

Pretreatment BRS was differentially related to clinical response for the treatment groups. Specifically, a significant decrease in pain severity was found in response to yoga for those participants who had lower resting BRS to activations, but decreased pain severity was associated with higher resting BRS for those in the walking group. The effect was not related to affective symptom relief. Other CV measures showed similar associations with clinical outcomes for both groups.

CONCLUSIONS

The data suggest therefore that CV based phenotypes may be useful in personalizing clinical interventions for IBS. They may also point to autonomic mechanisms that are targets for such interventions.

Prevalence and Characteristics of Chronic Spinal Pain Patients with Different Hopes (Treatment Goals) for Ongoing Chiropractic Care

Objectives: The treatment goals of patients successfully using ongoing provider-based care for chronic spinal pain can help inform health policy related to this care. Design: Multinomial logistical hierarchical linear models were used to examine the characteristics of patients with different treatment goals for their ongoing care. Settings/Location: Observational data from a large national sample of patients from 125 chiropractic clinics clustered in 6 U.S. regions. Subjects: Patients with nonwork-injury-related nonspecific chronic low-back pain (CLBP) and chronic neck pain (CNP). Interventions: All were receiving ongoing chiropractic care. Outcome measures: Primary outcomes were patient endorsement of one of four goals for their treatment. Explanatory variables included pain characteristics, pain beliefs, goals for mobility/flexibility, demographics, and other psychological variables. Results: Across our sample of 1614 patients (885 with CLBP and 729 with CNP) just under one-third endorsed a treatment goal of having their pain go away permanently (cure). The rest had goals of preventing their pain from coming back (22% CLBP, 16% CNP); preventing their pain from getting worse (14% CLBP, 12% CNP); or temporarily relieving their pain (31% CLBP, 41% CNP). In univariate analysis across these goals, patients differed significantly on almost all variables. In the multinomial logistic models, a goal of cure was associated with shorter pain duration and more belief in a medical cure; a goal of preventing pain from coming back was associated with lower pain levels; and those with goals of preventing their pain from getting worse or temporarily relieving pain were similar, including in having their pain longer. Conclusions: Although much of health policy follows a curative model, the majority of these CLBP and CNP patients have goals of pain management (using ongoing care) rather than "cure" (care with a specific end) for their chiropractic care. This information could be useful in crafting policy for patients facing provider-based nonpharmacologic care for chronic pain.

Physical and Physiological Effects of Yoga for an Underserved Population with Chronic Low Back Pain

Background

Yoga has been shown useful in reducing chronic low back pain (CLBP) through largely unknown mechanisms. The aim of this pilot study is to investigate the feasibility of providing yoga intervention to a predominantly underserved population and explore the potential mechanisms underlying yoga intervention in improving CLBP pain.

Methods

The quasi-experimental within-subject wait-listed crossover design targeted the recruitment of low-income participants who received twice-weekly group yoga for 12 weeks, following 6-12 weeks of no intervention. Outcome measures were taken at baseline, preintervention (6-12 weeks following baseline), and then postintervention. Outcome measures included pain, disability, core strength, flexibility, and plasma tumor necrosis factor (TNF)-α protein levels. Outcomes measures were analyzed by one-way ANOVA and paired one-tailed t-tests.

Results

Eight patients completed the intervention. Significant improvements in pain scores measured over time were supported by the significant improvement in pre- and post-yoga session pain scores. Significant improvements were also seen in the Oswestry Disability Questionnaire scores, spinal and hip flexor flexibility, and strength of core muscles following yoga. Six participants saw a 28.6%-100% reduction of TNF-α plasma protein levels after yoga, while one showed an 82.4% increase. Two participants had no detectable levels to begin with. Brain imaging analysis shows interesting increases in N-acetylaspartate in the dorsolateral prefrontal cortex and thalamus.

Conclusion

Yoga appears effective in reducing pain and disability in a low-income CLBP population and in part works by increasing flexibility and core strength. Changes in TNF-α protein levels should be further investigated for its influence on pain pathways.
