original researchYoga Reduces Performance Anxiety in Adolescent Musicians Sat Bir S. Khalsa, PhD; Bethany Butzer, PhD; Stephanie M. Shorter, PhD; Kristen M. Reinhardt, BM; Stephen Cope, MSW ABSTRACT Context • Professional musicians often experience high levels of stress, music performance anxiety (MPA), and performance-related musculoskeletal disorders (PRMDs). Given the fact that most professional musicians begin their musical training before the age of 12, it is important to identify interventions that will address these issues from an early age. Objective • This study intended to replicate and expand upon adult research in this area by evaluating the effects of a yoga intervention on MPA and PRMDs in a population of adolescent musicians. The present study was the first to examine these effects. Design • The research team assigned participants, adolescent musicians, into two groups. The intervention group (n = 84) took part in a 6-wk yoga program, and the control group (n = 51) received no treatment. The team evaluated the effects of the yoga intervention by comparing the scores of the intervention group to those of the control group on a number of questionnaires related to MPA and PRMDs. Setting • The study was conducted at the Boston University Tanglewood Institute (BUTI). BUTI is a training academy for advanced adolescent musicians, located in Lenox, Massachusetts. Sat Bir S. Khalsa, PhD, is assistant professor of medicine in the Department of Medicine at Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts; and research director at the Kripalu Center for Yoga and Health in Lenox, Massachusetts.

Intervention • Participants in the yoga intervention group were requested to attend three, 60-min, Kripalustyle yoga classes each wk for 6 wk. Outcome Measures • MPA was measured using the Performance Anxiety Questionnaire (PAQ) and the Music Performance Anxiety Inventory for Adolescents (MPAI-A). PRMDs were measured using the Performance-Related Musculoskeletal Disorders Questionnaire (PRMD-Q). Results • Yoga participants showed statistically significant reductions in MPA from baseline to the end of the program compared to the control group, as measured by several subscales of the PAQ and MPAI-A; however, the results for PRMDs were inconsistent. Conclusion • The findings suggest that yoga may be a promising way for adolescents to reduce MPA and perhaps even prevent it in the future. These findings also suggest a novel treatment modality that potentially might alleviate MPA and prevent the early disruption and termination of musical careers. (Altern Ther Health Med. 2013;19(2):3445.) rofessional musicians face many career stressors, such as music performance anxiety (MPA), the unpredictability of schedules for work and travel, and performance-related musculoskeletal disorders (PRMDs) resulting from demanding hours of training and practice.1 Survey studies estimate that as many as 69% of musicians are negatively impacted by MPA2,3 and as many as 87% of musicians experience PRMDs.3-5 Considering that most professional musicians begin their training before the age of 12,6 it would be advantageous to develop preventive interventions for MPA and PRMDs for young musicians. Early implementation of such interventions might support longer as well as more productive and satisfying musical careers. Based on recent research on the effectiveness of yoga and meditation for MPA in adults,7,8 the present study examines whether yoga would be a valuable preventive measure for adolescent musicians, particularly for MPA and PRMDs.

Future research is needed using a larger sample with higher levels of PRMDs as well as a longer yoga intervention to assess the degree and consistency with which yoga can benefit musicians’ musculoskeletal discomfort. Yoga participants. The limitations of nonrandom assignment. would recommend it to other musicians. participants were involved in an intense music fellowship program that became more challenging over time. performance evaluation anxiety. Other feedback on the postprogram evaluation suggested that yoga did not have as much of an impact on the technical and creative aspects of musical performance as it did on potentially alleviating MPA. somative/cognitive performance anxiety. PRMDs Yoga participants in the combined sample did not change from baseline to the end of the program in the frequency or severity of PRMDs or in the effort required to complete a daily music practice routine. such as trembling. one must exercise caution in drawing firm conclusions from this study. Regarding questions assessing whether participants found the yoga program beneficial to themselves as musicians. State and Trait Anxiety Yoga participants did not show significantly lower endof-program state anxiety compared to control participants. Six weeks may not be a long enough time for a yoga intervention to bring about consistent neuromuscular changes. and thus it was somewhat different from what would normally be encountered by musicians under more typical working circumstances. however. Thus. It is also possible that yoga might help reduce the fears that adolescent musicians may have about negative performance evaluations by authority figures such as teachers and parents. however. Yoga and meditation may not only be effective interventions for MPA but also for general. and total performance anxiety than the control group. Limitations The present study should be considered with several caveats in mind. mar/apr 2013. Interestingly. In addition. and fear of failure.

Future studies should examine the effects of yoga and meditation on adolescent musicians in more naturalistic settings. long-standing trait anxiety. endof-program. participants’ low baseline scores may have produced a floor effect that precluded meaningful reductions in PRMDs. should be addressed in future randomized controlled studies. Yoga participants in the 2008 sample. and planned to continue with yoga as a result of the program. showed signifiKhalsa—Yoga Reduces Anxiety in Adolescent Musicians cantly less severe PRMDs at the end of the program compared to control participants. and all of the mean exertion scores were below 14 (possible range 6-20). Perhaps the relatively short intervention used in the present study simply did not allow enough time to fundamentally change preferences for performing in a group versus a solo context. although the results were in the expected direction and are consistent with a positive effect of the yoga intervention. or other nonspecific effects of involvement in an active yoga intervention could account for the findings. On the MPAI-A. and the groups did not differ on any of the measures at baseline. The drop in state anxiety for yoga participants might have reached statistical significance with a larger sample or a longer intervention. suggesting that the groups were very similar to each other. the yoga participants did not show significantly different performance-context preferences at the end of the program compared to control participants. and yoga participants self-selected to participate in the yoga intervention. This finding is consistent with previous studies that have found positive correlations between trait anxiety and MPA. Yoga participants in the 2007 sample showed significantly lower trait anxiety at the end of the program compared to control participants. but not the 2007 sample. a greater number of females (n = 76 for the 43 ALTERNATIVE THERAPIES. VOL. 19. Thus. Other factors. First. These results are also consistent with previous research highlighting the anxiety-reducing effects of yoga in children and adolescents41 and add further credence to the growing yoga-therapy movement The fact that yoga participants in the 2008 sample did not show significantly lower trait anxiety at the end of the program compared to control participants was unexpected and is difficult to explain. the response pattern suggests that yoga may represent a useful and enjoyable way for adolescent musicians to reduce MPA. All of the mean frequency and severity scores for PRMD were below 25 (possible range 0-100).meaningful reductions in performance anxiety. increased heart rate. Yoga Program Evaluation Participants responded positively to the yoga program in a number of ways. participants were not randomized into the control condition. showed a numerical drop in state anxiety from baseline to the end of the program.19. attention effects. such as expectation effects. healthy musicians. One strength of the current study is that the control participants were drawn from the same population of adolescent music students. NO. with the yoga group showing significantly lower.54 as well as the 2009 findings of Khalsa et al8 in which an 8-week yoga intervention was related to decreases in tension and anxiety in adult musicians as measured by the Profile of Mood States questionnaire.2 . whereas control participants showed no such drop. These findings suggest that yoga might be an effective intervention to deal with both the cognitive and somatic symptoms of MPA. The MPAI-A results confirmed those found with the PAQ. Future research should examine this possibility. PRMD severity scores increased from baseline to the end of the program in the 2007 yoga sample. it also warrants further research. Second. It will be important for future research to examine the effectiveness of tailored yoga interventions for trait anxiety as well as specific anxiety and mood disorders. Musikphysiol Musikermed. 26.
