The Effect of Stabilization Exercises on Playing Performance in Musicians With Joint Hyperlaxity

Abstract

Purpose/Hypothesis: Joint hypermobility is defined as an abnormal increase in the range of active and passive motion, which is a very common situation in musicians. However, its relation to injuries and on musical performance is not clear; it is thought that unstable joint can be harmed with repetitive playing task. Therefore, stabilization exercises can have a positive effect in hypermobile hands. This study is aimed to investigate the effect of stabilization exercises in musicians having hypermobile joints. Material and Methods: Seventy-five musicians who are playing string instruments and piano at conservatory were assessed if they have joint laxity, and it was found that 45% of this population had joint laxity. The ones who had laxity have asked if they would like to attend to an exercise program aiming stabilization. Twelve people accepted to do the exercises. These 12 people have been assessed by Disability of Arm, Shoulder and Hand (DASH). In addition, they are asked to rate their musical performance, fatigue, and pain according to visual analogue scale, and hand strength was evaluated with pinchmeter. Stabilization exercises were given for 4 weeks; once a week, students worked with the therapist, and during the whole week, they did home exercises. Ten people completed the exercise program, and they were evaluated again at the end of the month. Results: The mean DASH score (musician part) of the musicians was 25.12; this score decreased significantly ( P < .05) after exercises. Also hand strength and musical performance increased significantly( P < .05). Conclusion: When treating a musician patient, if she or he has joint hyperlaxity, adding stabilization exercises to rehabilitation program can be useful. It is also suggested that musicians with hypermobile joints can do stabilization exercises to prevent their joints from injury and to increase musical performance. Preventive programs of musicians mostly include stretching exercises, however 1 or 2 stabilization exercise can be added for especially musicians with hyperbole joints.
