Effects of a 12-week yoga versus a 12-week educational film intervention on symptoms of restless legs syndrome and related outcomes: an exploratory randomized controlled trial.

STUDY OBJECTIVES: To assess the effects of a yoga versus educational film (EF) program on restless legs syndrome (RLS) symptoms and related outcomes in adults with RLS. METHODS: Forty-one community-dwelling, ambulatory nonpregnant adults with moderate to severe RLS were randomized to a 12-week yoga (n = 19) or EF program (n = 22). In addition to attending classes, all participants completed practice/treatment logs. Yoga group participants were asked to practice at home 30 minutes per day on nonclass days; EF participants were instructed to record any RLS treatments used on their daily logs. Core outcomes assessed pretreatment and posttreatment were RLS symptoms and symptom severity (International RLS Study Group Scale (IRLS) and RLS ordinal scale), sleep quality, mood, perceived stress, and quality of life (QOL). RESULTS: Thirty adults (13 yoga, 17 EF), aged 24 to 73 (mean = 50.4 ± 2.4 years), completed the 12-week study (78% female, 80.5% white). Post-intervention, both groups showed significant improvement in RLS symptoms and severity, perceived stress, mood, and QOL-mental health (P ≤ .04). Relative to the EF group, yoga participants demonstrated significantly greater reductions in RLS symptoms and symptom severity (P ≤ .01), and greater improvements in perceived stress and mood (P ≤ .04), as well as sleep quality (P = .09); RLS symptoms decreased to minimal/mild in 77% of yoga group participants, with none scoring in the severe range by week 12, versus 24% and 12%, respectively, in EF participants. In the yoga group, IRLS and RLS severity scores declined with increasing minutes of homework practice (r = .7, P = .009 and r = .6, P = .03, respectively), suggesting a possible dose-response relationship. CONCLUSIONS: Findings of this exploratory RCT suggest that yoga may be effective in reducing RLS symptoms and symptom severity, decreasing perceived stress, and improving mood and sleep in adults with RLS.

Preliminary efficacy of a lovingkindness meditation intervention for patients undergoing biopsy and breast cancer surgery: A randomized controlled pilot study.

PURPOSE: Despite more women undergoing treatment for breast cancer and increased survival rates, many women suffer from anxiety and physical symptoms (e.g., pain, fatigue) surrounding diagnosis and surgery. Research investigating the efficacy of psychosocial interventions for breast cancer patients during this period is limited. This randomized controlled pilot study examined the effect of a brief lovingkindness meditation intervention on these key outcomes. METHODS: Participants were 60 women who underwent core needle breast biopsy, received an abnormal biopsy result, and underwent breast surgery (White = 73.6%; African American = 22.6%; Asian American = 3.8%; Age M = 56). Participants were randomly assigned to one of three treatment conditions at breast biopsy: (1) lovingkindness meditation, (2) music, and (3) usual care. Assessments of anxiety, pain, fatigue, physiologic reactivity, and self-compassion occurred prior to patients' biopsy, following biopsy, 1 week after receipt of biopsy results, and 1 week following breast surgery. RESULTS: Multilevel modeling analyses demonstrated that lovingkindness meditation significantly improved pain (p = 0.02), self-compassion (p = 0.004), and heart rate (p = 0.02) over time compared to control conditions. There was a trend for anxiety (p = 0.05). Music significantly improved pain (p = 0.04) compared to usual care. CONCLUSIONS: These findings provide preliminary evidence for the feasibility and efficacy of a lovingkindness meditation intervention for breast cancer patients during the diagnostic and surgical period. Improving psychological and physical well-being during this time frame has the potential to improve longer-term health outcomes during adjuvant treatment and survivorship. Interventions that cultivate positive adjustment during the diagnostic and surgical period of breast cancer are an important area of future research.

Effects of Meditation and Music-Listening on Blood Biomarkers of Cellular Aging and Alzheimer's Disease in Adults with Subjective Cognitive Decline: An Exploratory Randomized Clinical Trial.

BACKGROUND: Telomere length (TL), telomerase activity (TA), and plasma amyloid-ß (Aß) levels have emerged as possible predictors of cognitive decline and dementia. OBJECTIVE: To assess the: 1) effects of two 12-week relaxation programs on TL, TA, and Aß levels in adults with subjective cognitive decline; and 2) relationship of biomarker changes to those in cognitive function, psychosocial status, and quality of life (QOL). METHODS: Participants were randomized to a 12-week Kirtan Kriya meditation (KK) or music listening (ML) program and asked to practice 12 minutes/day. Plasma Aß(38/40/42) and peripheral blood mononuclear cell TL and TA were measured at baseline and 3 months. Cognition, stress, sleep, mood, and QOL were assessed at baseline, 3 months, and 6 months. RESULTS: Baseline blood samples were available for 53 participants (25 KK, 28 ML). The KK group showed significantly greater increases in Aß40 than the ML group. TA rose in both groups, although increases were significant only among those with higher practice adherence and lower baseline TA. Changes in both TL and TA varied by their baseline values, with greater increases among participants with values ≤50th percentile (ps-interaction <0.006). Both groups improved in cognitive and psychosocial status (ps ≤0.05), with improvements in stress, mood, and QOL greater in the KK group. Rising Aß levels were correlated with gains in cognitive function, mood, sleep, and QOL at both 3 and 6 months, associations that were particularly pronounced in the KK group. Increases in TL and TA were also correlated with improvements in certain cognitive and psychosocial measures. CONCLUSION: Practice of simple mind-body therapies may alter plasma Aß levels, TL, and TA. Biomarker increases were associated with improvements in cognitive function, sleep, mood, and QOL, suggesting potential functional relationships.

Effects of Mantra Meditation versus Music Listening on Knee Pain, Function, and Related Outcomes in Older Adults with Knee Osteoarthritis: An Exploratory Randomized Clinical Trial (RCT).

OBJECTIVE: Disease-modifying treatments for OA remain elusive, and commonly used medications can have serious side effects. Although meditation and music listening (ML) have been shown to improve outcomes in certain chronic pain populations, research in OA is sparse. In this pilot RCT, we explore the effects of two mind-body practices, mantra meditation (MM) and ML, on knee pain, function, and related outcomes in adults with knee OA. METHODS: Twenty-two older ambulatory adults diagnosed with knee OA were randomized to a MM (N=11) or ML program (N=11) and asked to practice 15-20 minutes, twice daily for 8 weeks. Core outcomes included knee pain (Knee Injury and Osteoarthritis Outcome Score [KOOS] and Numeric Rating Scale), knee function (KOOS), and perceived OA severity (Patient Global Assessment). Additional outcomes included perceived stress (Perceived Stress Scale), mood (Profile of Mood States), sleep (Pittsburgh Sleep Quality Index), and health-related quality of life (QOL, SF-36). Participants were assessed at baseline and following completion of the program. RESULTS: Twenty participants (91%) completed the study (9 MM, 11 ML). Compliance was excellent; participants completed an average of 12.1±0.83 sessions/week. Relative to baseline, participants in both groups demonstrated improvement post-intervention in all core outcomes, including knee pain, function, and perceived OA severity, as well as improvement in mood, perceived stress, and QOL (Physical Health) (p's≤0.05). Relative to ML, the MM group showed greater improvements in overall mood and sleep (p's≤0.04), QOL-Mental Health (p<0.07), kinesiophobia (p=0.09), and two domains of the KOOS (p's<0.09). CONCLUSIONS: Findings of this exploratory RCT suggest that a simple MM and, possibly, ML program may be effective in reducing knee pain and dysfunction, decreasing stress, and improving mood, sleep, and QOL in adults with knee OA.

A Preliminary Exploration of the Application of Self-Compassion Within the Context of Sport Injury.

In a prospective study of collegiate athletes (N = 117), the application of self-compassion within the context of sport injury was explored. Previous literature indicated that self-compassion enhances adaptive coping and well-being and reduces anxiety in stress-provoking situations. This research suggested that it could potentially reduce the stress response and subsequent injury risk. Findings indicated that self-compassion may buffer the experience of somatic anxiety (rs = -.436, p < .01) and worry (rs = -.351, p < .01), and reduce the engagement of avoidance-focused coping strategies (rs = -.362, p < .01). There were no significant findings related to self-compassion and injury reduction. A challenge with this research is distinguishing the impact of resistance to self-compassion from the potential benefits that it may have on coping and appraisal of stress in sport. This research was a preliminary exploration of self-compassion within the context of responses to stress and subsequent injury risk. Results suggest that further investigation across different athletic populations, sports, and injury situations is warranted.
