Compared to aerobic exercise , no short- or medium-term group differences in depression severity was found .
Higher short-term depression severity was found for yoga compared to electro-convulsive therapy ;  remission rates did not differ between groups .
No short-term group differences occurred when yoga was compared to antidepressant medication .
Conflicting evidence was found when yoga was compared to attention-control interventions , or when yoga as an add-on to antidepressant medication was compared to medication alone .
This review found some evidence for positive effects beyond placebo and comparable effects compared to evidence -based interventions .
BACKGROUND The purpose of this review was to investigate the efficacy and safety of yoga interventions in treating patients with major depressive disorder .
Yoga as a treatment for chronic low back pain: A systematic review of the literature
Objectives Chronic low back pain ( CLBP ) affects millions of people worldwide , and appears to be increasing in prevalence . It is associated not only with pain , but also with increased disability , psychological symptoms , and reduced quality of life . There are various treatment options for CLBP , but no single therapy st and s out as being the most effective . In the past 10 years , yoga interventions have been studied as a CLBP treatment approach . The objective of this paper is to review the current literature supporting the efficacy of yoga for CLBP . Methods A literature search through the beginning of 2015 was conducted in Pub Med for r and omized control trials addressing treatment of CLBP with yoga . Results In this review we evaluate the use of yoga as a treatment for CLBP . Specifically we evaluate how yoga impacts physical functioning and disability , pain , and associated psychological symptoms . We also evaluate possible mediators of the effect of yoga and the safety of yoga . Discussion With few exceptions , previous studies and the recent r and omized control trials ( RCTs ) indicate that yoga can reduce pain and disability , can be practice d safely , and is well received by participants . Some studies also indicate that yoga may improve psychological symptoms , but these effects are currently not as well established
