The posture has a major influence on the body; e.g., a slumped posture can lead to increased tissue loading but also altered movement behavior. Musicians, including violinists/violists, have a high prevalence of upper body musculoskeletal disorders. Biomechanical risk factors include repetitive movements, altered muscle activation and awkward postures. Changes in posture may have implications for both injury risk and the musical performance. Ideally, a healthy posture leads to the desired qualities of the performance, but this is still to be investigated. This multidisciplinary study takes an initial step to unravel the impact on both movement behavior and musical quality related to playing posture among high string musicians.
