OBJECTIVES: To assess the feasibility, safety, and initial estimates of efficacy of a yoga program in postoperative care for women at high risk for breast cancer-related lymphedema (BCRL). DESIGN: Single-group pretest-post-test design. SETTINGS/LOCATION: Patients were recruited from the University of California, San Francisco Carol Franc Buck Breast Care Center. SUBJECTS: Twenty-one women were enrolled in the study. Women were >18 years of age, had undergone surgical treatment for breast cancer, and were at high risk for BCRL. INTERVENTION: The women participated in an Ashtanga yoga intervention for 8 weeks. Sessions consisted of once/week instructor-led practice and once/week home practice. Particular attention was given to poses that emphasized upper body strength and flexibility, while avoiding significant time with the upper extremity (UE) in a dependent position. OUTCOME MEASURES: UE volume was assessed through circumferential forearm measurement, which was converted to volume using the formula for a truncated cone. Range of motion (ROM) was assessed for the shoulders, elbows, and wrists, using a standard goniometer. UE strength was assessed for shoulder abduction, elbow flexion, wrist flexion, and grip using a dynamometer. RESULTS: Twenty women completed the yoga intervention, with 17 returning for final assessment. Mean age was 52 (+/-9.1) years and body mass index was 24.8 (+/-5.1) kg/m(2). Postintervention, mean volume in the at-risk UE was slightly reduced (p = 0.397). ROM for shoulder flexion (p < 0.01) and external rotation (p < 0.05) significantly increased bilaterally. Shoulder abduction ROM significantly improved for the unaffected limb (p = 0.001). Following intervention, strength improved on the affected side for shoulder abduction and grip strength, and bilaterally for elbow flexion (p < 0.05 for all). CONCLUSIONS: These preliminary findings suggest that yoga is feasible and safe for women who are at risk for BCRL and may result in small improvements in shoulder ROM and UE strength.

Applied Relaxation (AR), which involves noticing early signs of anxiety and responding with a relaxation response, is an empirically supported treatment for Generalized Anxiety Disorder (GAD). However, research on hypothesized mechanisms of AR (e.g., reduced muscle tension) has been mixed, making it likely that additional mechanisms are contributing to the efficacy of AR. Stemming from more recent conceptualizations of GAD, it is hypothesized that mindfulness, decentering, and acceptance may be potential mechanisms of change in AR. Outcome, mechanism data, and case descriptions from three individuals diagnosed with GAD who received 16 weeks of AR as part of a larger randomized controlled trial are presented to demonstrate the ways that AR may lead to clinical improvement through mindfulness, decentering, and acceptance.
Diminished levels of mindfulness (awareness and acceptance/nonjudgment) and difficulties in emotion regulation have both been proposed to play a role in symptoms of generalized anxiety disorder (GAD); the current studies investigated these relationships in nonclinical and clinical samples. In the first study, among a sample of 395 individuals at an urban commuter campus, self-reports of both emotion regulation difficulties and aspects of mindfulness accounted for unique variance in GAD symptom severity, above and beyond variance shared with depressive and anxious symptoms, as well as variance shared with one another. In the second study, individuals with GAD (n=16) reported significantly lower levels of mindfulness and significantly higher levels of difficulties in emotion regulation than individuals in a nonanxious control group (n=16). Results are discussed in terms of directions for future research and potential implications for treatment development.
This systematic review aims to evaluate the therapeutic effects of yoga therapy using an evidence-based approach and investigates the relationship between yoga and the meridian energies based on all available clinical studies in Korea. Sixteen electronic databases will be searched from the inception of the study until January 2016. All clinical evidences that evaluate any type of yoga and any type of control in individuals with any type of condition will be eligible. The methodological quality will be assessed using the Cochrane risk of bias tool for randomized clinical trials and the Newcastle-Ottawa scale for nonrandomized studies. Two authors will independently assess each study for eligibility and the risk of bias, and then they will extract the data. With its extensive, unbiased search of the Korean literature from various databases without any language restrictions, this systematic review will be useful for both practitioners in the field of yoga research as well as for patients.
