The study of wrist postures of musicians using the WristSystem (Greenleaf Medical System).
This study examined wrist motions of instrumentalists who have never experienced a cumulative traumatic disorder. Eighteen student musicians ranging from 18 to 29 years of age, with more than 9 years of playing experience participated in this study using the WristSystem (Greenleaf Medical System). The wrist motions were measured while participants played their instrument for five minutes. The results indicated a different pattern of wrist movements for each instrumentalist. Pianists demonstrated more ulnar deviation for both hands and more flexion for the left hand than any of the other instrumentalists. The average wrist range of motion for all four movements was under 15 degrees for violinists and violists. The right hand of the cellist had more flexion than any other instrumentalists. For both hands, flutists had more wrist extension than any other instrumentalists. This study provided information about wrist motions of musicians as one of the many factors that contribute to cumulative traumatic disorders. However, further research is needed to identify causal factors, and to promote prevention of the injury.
