A pilot study of yoga for chronic headaches in youth: promise amidst challenges.

The primary aim of the current study was to provide preliminary data on the feasibility, acceptability, and safety of alignment-based yoga for youths with chronic headaches. A secondary aim was to provide preliminary estimates of yoga's ability to improve headache pain, daily functioning, quality of life, and anxiety level in this population. The yoga intervention consisted of 8 weekly, 75-minute classes. Participant flow data revealed challenges to feasibility primarily due to recruitment and retention. Scores on most outcome measures changed in the predicted direction with medium effect sizes found for the functional outcomes. Pain measures did not change significantly. This pilot suggests that yoga for pediatric headaches may be acceptable, as indicated by positive parent and participant ratings of the yoga experience. These preliminary findings suggest that yoga trials for pediatric headaches include both challenges and promise. Recommendations for overcoming challenges include designs that optimize family convenience.

A Pilot Study of Iyengar Yoga for Pediatric Obesity: Effects on Gait and Emotional Functioning.

Obesity negatively impacts the kinematics and kinetics of the lower extremities in children and adolescents. Although yoga has the potential to provide several distinct benefits for children with obesity, this is the first study to examine the benefits of yoga for gait (primary outcome) in youths with obesity. Secondary outcomes included health-related quality of life (HRQoL), physical activity, and pain. Feasibility and acceptability were also assessed. Nine youths (11⁻17 years) participated in an eight-week Iyengar yoga intervention (bi-weekly 1-h classes). Gait, HRQOL (self and parent-proxy reports), and physical activity were assessed at baseline and post-yoga. Pain was self-reported at the beginning of each class. Significant improvements were found in multiple gait parameters, including hip, knee, and ankle motion and moments. Self-reported and parent-proxy reports of emotional functioning significantly improved. Time spent in physical activity and weight did not change. This study demonstrates that a relatively brief, non-invasive Iyengar yoga intervention can result in improved malalignment of the lower extremities during ambulation, as well as in clinically meaningful improvements in emotional functioning. This study extends current evidence that supports a role for yoga in pediatric obesity.
