Exercise DVD effect on musculoskeletal disorders in professional orchestral musicians.

BACKGROUND Professional musicians report a high prevalence of performance-related musculoskeletal disorders (PRMDs). Excessive muscle tension and fatigue have been reported as important factors contributing to PRMDs. AIMS To evaluate feasibility and effectiveness of a specific exercise programme delivered via a digital video disc (DVD) targeting PRMDs and associated risk factors. METHODS Volunteers from eight Australian symphony orchestras undertook two or more sessions per week over 12 weeks. Questionnaires were administered pre- and post-intervention with items including the frequency and severity of PRMDs, perceived exertion during different playing situations, per formance effects of the DVD and satisfaction rates. Musicians who had also participated in an equivalent face-to-face programme prior to this DVD trial compared the two interventions. RESULTS One hundred and forty-four out of 576 musicians volunteered (25% uptake), and 50 participants completed a mean 2.1 (SD 0.42) sessions over the 12 week period (41% compliance). PRMD frequency and severity were significantly reduced post-intervention (P < 0.01). Participants reported benefits of the DVD on strengthening muscles, increasing ease of movement and improving flexibility related to playing. Despite this, perceived exertion levels during private practice, rehearsal and performance remained the same (not significant). Seventy-eight per cent of participants scored their overall experience of the use of the DVD as good or excellent. Owing to its convenience and detailed exercise demonstrations, the DVD was rated as better or much better overall than the face-to-face classes by 55% of participants who had experienced both. CONCLUSIONS An exercise DVD was well received and appeared to be effective, convenient and safe in managing occupational-specific musculoskeletal disorders in musicians.
