Teleyoga for Patients With Alzheimer's Disease and Chronic Musculoskeletal Pain and Their Caregivers: A Feasibility Study.

Background: Chronic musculoskeletal pain is common in patients with Alzheimer's disease (AD), and there is growing awareness that chronic pain has an impact on the progression of dementia. Yoga has shown promise in treating chronic pain. However, attending in-person yoga can be difficult for AD patients. Objective: To assess the feasibility, acceptability and preliminary efficacy of an online yoga (teleyoga) protocol suitable for AD patients with chronic pain, and their caregivers. Methods: Patients with comorbid mild AD and chronic musculoskeletal pain (n = 15, 57-95 y/o; 73% Female) and their caregivers (n = 15, 50-75 y/o; 67% Female) received 12-week of teleyoga individually (n = 5 dyads) or in groups (n = 10 dyads). Study measures included standard feasibility metrics, and secondary outcomes included the Brief Pain Inventory-Short Form (BPI-SF), Beck Depression Inventory-II (BDI-II), and cognitive function using the Cambridge Neuropsychological Test Automated Battery (CANTAB). Caregivers also completed measures of caregiver burden, and quality of life (Short Form Health Survey-36, SF-36). Results: Feasibility measures showed adequate treatment adherence (85.1% in patients and 86.3% in caregivers), acceptability (mean acceptability rating = 3.0 for patients and 3.3 for caregivers, indicating positive approval), recruitment rate (n = 16 dyads within 1-year), retention rate (87%), missing data rate (.03%), and fidelity of treatment delivery (87%). Preliminary efficacy findings in the AD group showed significant reductions in pain severity (BPI-SF mean Δ = -.93, P = .045) and depression (BDI-II; mean Δ = -9.85, P = .005). %). Preliminary efficacy findings in the caregiver group showed significant reductions in depression (BDI-II mean Δ = -6.88, P = .036) and fatigue (SF-36 mean Δ = 9.81, P = .021). Conclusion: Results show that teleyoga is a feasible treatment for patients with comorbid mild AD and chronic musculoskeletal pain. Results also provide preliminary evidence of health benefits of teleyoga for both AD patients and their caregivers.

Yoga is effective for treating chronic pain in veterans with Gulf War Illness at long-term follow-up.

BACKGROUND: Clinical Practice Guidelines for Gulf War Illness (GWI) recommend integrative health approaches such as yoga for relief from symptoms, yet little is known about the long-term efficacy of yoga in reducing symptoms of GWI. Here, we evaluated the long-term efficacy of yoga and cognitive-behavioral therapy (CBT) chronic pain treatment in a randomized controlled trial (RCT) of 75 Veterans (57 men, 42-71 ± 7.1 years of age) with Gulf War Illness (GWI). METHODS: Participants received either 10 weeks of yoga or 10 weeks of CBT for chronic pain. The primary outcome measures were pain severity, and pain interference (Brief Pain Inventory-Short Form). The secondary outcome measures were fatigue, as indicated by a measure of functional exercise capacity (6-Minute Walk Test), depression, autonomic symptom severity, and quality of life. Piecewise linear mixed models were used to examine study hypotheses. RESULTS: Compared to the CBT group, yoga was associated with greater reductions in pain severity during the 6-month follow-up period (group × time interaction: b = 0.036, se = 0.014, p = .011). Although we did not find between-group differences in the other primary or secondary outcome measures during follow-up (p's > 0.05), exploratory analyses revealed within-group improvements in pain interference, total pain (an experimental outcome variable which combines pain severity and interference), and fatigue in the yoga group (p's < 0.05) but not in the CBT group. CONCLUSIONS: This is the first study to report long-term follow-up results of yoga as a treatment for GWI. Our results suggest that yoga may offer long-term efficacy in reducing pain, which is a core symptom of GWI. TRIAL REGISTRATION: Secondary analyses of ClinicalTrials.gov NCT02378025.

Posttraumatic Stress Disorder Does Not Compromise Behavioral Pain Treatment: Secondary Analysis of a Randomized Clinical Trial Among Veterans.

BACKGROUND: Individuals with posttraumatic stress disorder (PTSD) and chronic pain evince different presentations, coping strategies, and treatment utilization patterns than individuals with chronic pain alone. Theorists have suggested that comorbid PTSD may complicate chronic pain treatment, and that integrated pain and PTSD treatment may be preferable to pain treatment alone. OBJECTIVE: Assess whether comorbid PTSD moderates Veterans' response to yoga and/or cognitive behavioral therapy (CBT) for pain. METHODS: Veterans with Gulf War illness (n = 75) were assessed using the Brief Pain Inventory at baseline and posttreatment as part of a randomized clinical trial. PTSD status was abstracted from participants' medical records. RESULTS: PTSD+ participants (n = 41) reported more pain at baseline than PTSD- participants (n = 34; d = .66, p < .01). PTSD+ participants experienced more improvement in pain from baseline to posttreatment than PTSD- participants by a small to moderate, marginally statistically significant amount (d = .39, p = .07). The relationship between PTSD and treatment outcome was not moderated by treatment type (yoga vs CBT; p = .99). Observation of treatment responses across PTSD status (+ vs -) and treatment (yoga vs CBT) revealed that PTSD+ participants responded well to yoga. CONCLUSION: PTSD is not associated with reduced effectiveness of behavioral chronic pain treatment among Veterans with Gulf War illness. Therefore behavioral pain treatment should be made readily available to Veterans with pain and PTSD. Yoga deserves further consideration as a treatment for pain among individuals with PTSD.

Self-Reported Autonomic Dysregulation in Gulf War Illness.

INTRODUCTION: Autonomic nervous system dysregulation is commonly observed in Gulf War illness (GWI). Using a new sample, we sought to replicate and extend findings from a previous study that found autonomic symptoms predicted physical functioning in Veterans with GWI. MATERIALS AND METHODS: A linear regression model was used to predict physical functioning (36-item Short Form Health Survey (SF-36); n = 73, 75% male). First, we examined the predictive value of independent variables individually in the model including: the 31-item Composite Autonomic Symptom Score (COMPASS-31) total score, body mass index (BMI), mental health burden (i.e., post-traumatic stress disorder [PTSD] and/or depression), and COMPASS-31 subscales: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor. Next, we estimated linear regression models containing the three variables (autonomic symptoms, BMI, and mental health burden) identified as predictors of physical functioning from the prior study. RESULTS: These linear regression models significantly predicted physical functioning and accounted for 15% of the variance with COMPASS-31, 36.6% of variance with COMPASS-31 and BMI, and 38.2% of variance with COMPASS-31, BMI, and mental health burden. Then, forward step-wise linear regressions were applied to explore new models including COMPASS-31 subscales. Two new models accounted for more of the variance in physical functioning: 39.3% with added gastrointestinal symptoms (ß = -2.206, P = .001) and 43.4% of variance with both gastrointestinal (ß = -1.592, P = .008) and secretomotor subscales (ß = -1.533, P = .049). Unlike the previous study we intended to replicate, mental health burden was not a significant predictor in any of our models. CONCLUSIONS: Treatments that address autonomic dysregulation should be prioritized for research and clinical recommendations for Veterans with GWI who experience chronic pain.

Heart rate and heart rate variability as outcomes and longitudinal moderators of treatment for pain across follow-up in Veterans with Gulf War illness.

AIMS: Accumulating evidence suggests Gulf War illness (GWI) is characterised by autonomic nervous system dysfunction (higher heart rate [HR], lower heart rate variability [HRV]). Yoga - an ancient mind-body practice combining mindfulness, breathwork, and physical postures - is proposed to improve autonomic dysfunction yet this remains untested in GWI. We aimed to determine (i) whether HR and HRV improve among Veterans with GWI receiving either yoga or cognitive behavioural therapy (CBT) for pain; and (ii) whether baseline autonomic functioning predicts treatment-related pain outcomes across follow-up. MAIN METHODS: We present secondary analyses of 24-hour ambulatory cardiac data (mean HR, square root of the mean squared differences between successive R-R intervals [RMSSD], high frequency power [HF-HFV], and low-to-high frequency ratio [LF/HF] extracted from a 5-min window during the first hour of sleep) from our randomised controlled trial of yoga versus CBT for pain among Veterans with GWI (ClinicalTrials.govNCT02378025; N = 75). KEY FINDINGS: Veterans who received CBT tended towards higher mean HR at end-of-treatment. Better autonomic function (lower mean HR, higher RMSSD/HF-HRV) at baseline predicted greater reductions in pain across follow-up, regardless of treatment group. Better baseline autonomic function (mid-range-to-high RMSSD/HF-HRV) also predicted greater pain reductions with yoga, while worse baseline autonomic function (higher mean HR, lower RMSSD/HF-HRV) predicted greater pain reductions with CBT. SIGNIFICANCE: To our knowledge, this is the first study to suggest that among Veterans with GWI, HR may increase with CBT yet remain stable with yoga. Furthermore, HR and HRV moderated pain outcome across follow-up for yoga and CBT.

Clinical yoga program utilization in a large health care system.

The U.S. Department of Veterans Affairs (VA) offers yoga for multiple conditions. Little information is available regarding how frequently yoga is utilized, by whom, or for which medical conditions. Here we describe referral patterns and patient adoption rates in a clinical yoga program, including telehealth yoga, at VA Palo Alto Health Care System (VAPAHCS). Referral and demographic data were extracted from the electronic medical records of 953 veterans (692 male, 261 female) referred to the outpatient clinical yoga program between 2010 and 2016. Attendance data were extracted from the same time plus 1 year. Referee demographics were compared to the overall VAPAHCS population. Twenty-two of the 187 referring providers accounted for half (50.4%) of referrals, predominantly from primary care and mental health clinics. Compared to the overall VAPAHCS patient population, referees were similar age and more likely to be female. Attendance was associated with age (older veterans were more likely to attend) but not gender. Those referred for mental health reasons were more likely to attend yoga compared to those referred for physical symptoms or for wellness (e.g., strength, health, mindfulness). Telehealth yoga follow through was lower but attendance rate similar to in-person yoga. These data provide an overview of referral and uptake in a large VA setting. Overall, referral was performed by a few providers in mental health and primary care clinics. The typical demographic of attendee was a White male from the Vietnam War era, reflective of the VA population. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Yoga is effective in treating symptoms of Gulf War illness: A randomized clinical trial.

Many Veterans of the 1990-1991 Gulf War report symptoms of Gulf War Illness, a condition involving numerous chronic symptoms including pain, fatigue, and mood/cognition symptoms. Little is known about this condition's etiology and treatment. This study reports outcomes from a randomized controlled single-blind trial comparing yoga to cognitive behavioral therapy for chronic pain and other symptoms of Gulf War Illness. Participants were Veterans with symptoms of GWI: chronic pain, fatigue and cognition-mood symptoms. Seventy-five Veterans were randomized to treatment via selection of envelopes from a bag (39 yoga, 36 cognitive behavioral therapy), which consisted of ten weekly group sessions. The primary outcomes of pain severity and interference (Brief Pain Inventory- Short Form) improved in the yoga condition (Cohen's d = .35, p = 0.002 and d = 0.69, p < 0.001, respectively) but not in the CBT condition (d = 0.10, p = 0.59 and d = 0.25 p = 0.23). However, the differences between groups were not statistically significant (d = 0.25, p = 0.25; d = 0.43, p = 0.076), though the difference in an a-priori-defined experimental outcome variable which combines these two variables into a total pain variable (d = 0.47, p = 0.047) was significant. Fatigue, as indicated by a measure of functional exercise capacity (6-min walk test) was reduced significantly more in the yoga group than in the CBT group (between-group d = .27, p = 0.044). Other secondary outcomes of depression, wellbeing, and self-reported autonomic nervous system symptoms did not differ between groups. No adverse events due to treatment were reported. Yoga may be an effective treatment for core Gulf War Illness symptoms of pain and fatigue, making it one of few treatments with empirical support for GWI. Results support further evaluation of yoga for treating veterans with Gulf War Illness. CLINICAL TRIAL REGISTRY: clinicaltrials.gov Registration Number NCT02378025.

Tele-yoga for Chronic Pain: Current Status and Future Directions.

Pain is a pervasive, debilitating disorder that is resistant to long-term pharmacological interventions. Although psychological therapies such as cognitive behavior therapy demonstrate moderate efficacy, many individuals continue to have ongoing difficulties following treatment. There is a current trend to establish complementary and integrative health interventions for chronic pain, for which yoga has been found to have exciting potential. Nevertheless, an important consideration within the field is accessibility to adequate care. Telehealth can be used to provide real-time interactive video conferencing leading to increased access to health care for individuals located remotely or who otherwise have difficulty accessing services, perhaps through issues of mobility or proximity of adequate services. This article assesses the current status and feasibility of implementing tele-yoga for chronic pain. Methodological limitations and recommendations for future research are discussed.

Results from a clinical yoga program for veterans: yoga via telehealth provides comparable satisfaction and health improvements to in-person yoga.

BACKGROUND: Yoga is increasingly popular, though little data regarding its implementation in healthcare settings is available. Similarly, telehealth is being utilized more frequently to increase access to healthcare; however we know of no research on the acceptability or effectiveness of yoga delivered through telehealth. Therefore, we evaluated the feasibility, acceptability, and patient-reported effectiveness of a clinical yoga program at a Veterans Affairs Medical Center and assessed whether these outcomes differed between those participating in-person and those participating via telehealth. METHODS: Veterans who attended a yoga class at the VA Palo Alto Health Care System were invited to complete an anonymous program evaluation survey. RESULTS: 64 Veterans completed the survey. Participants reported high satisfaction with the classes and the instructors. More than 80% of participants who endorsed a problem with pain, energy level, depression, or anxiety reported improvement in these symptoms. Those who participated via telehealth did not differ from those who participated in-person in any measure of satisfaction, overall improvement (p = .40), or improvement in any of 16 specific health problems. CONCLUSIONS: Delivering yoga to a wide range of patients within a healthcare setting appears to be feasible and acceptable, both when delivered in-person and via telehealth. Patients in this clinical yoga program reported high levels of satisfaction and improvement in multiple problem areas. This preliminary evidence for the effectiveness of a clinical yoga program complements prior evidence for the efficacy of yoga and supports the use of yoga in healthcare settings.

A Role for Complementary and Integrative Medicine in Alzheimer's Disease Prevention.

Complementary and Integrative Medicine has been maturing as a field to support treatment for a variety of medical conditions. The approaches, including yoga, meditation, acupuncture, and dietary supplements, may assist patients in a variety of ways, though clear explanations for their mechanisms of action or measurements of their possible benefit are in most cases elusive. In this issue of the Journal of Alzheimer's Disease, Khalsa examines the use of meditation as a stress-reduction technique and provides an argument that with a specific technique such stress reduction can be provided efficiently, with relatively little interference in daily activities, and might decrease Alzheimer risk. This thorough review provides some evidence of physiological benefit of meditation to brain function. While any actual effect of meditation on Alzheimer pathophysiology is only conjectural, meditation has received considerable attention as a tool that may have positive psychological and medical benefits. Consequently, this review is welcome. What is less certain is whether the recommended meditation approach is of specific benefit for Alzheimer's disease or any other condition above and beyond what might be provided by many other types of exercises (like singing in a chorus or doing cross-word puzzles) or physical activities (like swimming or yoga).
