Approximately 64% to 76% of symphony orchestra musicians have experienced repetitive strain injuries (RSI) affecting their performance, not including those who have abandoned their careers because of serious injury. RSI is generally described as pain felt in muscles, nerves, and tendons caused by repetitive movement and overuse. RSI can be prevented by maintaining proper posture, taking frequent breaks, and breathing exercises. For musicians, RSI appear to be directly related to static and dynamic stresses inherent in playing a given instrument. For example, a violinist utilizing improper technique is prone to RSI in the jaw, back, neck, shoulder and hands, which can be related to either nerves or muscles. The scope of this project focuses on understanding musculoskeletal overuse or misuse of the violin bowing arm leading to RSI. Specifically, surface electromyography and 3D motion analysis will be used to generate comparative 3D models to examine difference in muscle activity from improper versus proper violin bowing technique.
