Background: The professional musician is required to practice daily for an average of about six to eight hours. Practice sessions would typically require the artist to use the same muscles repeatedly. Factors such as poor playing postures and inadequate rest periods predispose artists to repetitive stress injuries over a period of time.Context and purpose of study: The profession of piano playing involves the meticulous use of the various intrinsic muscles of the hand. Repeated exposure to micro trauma over a period of time has a direct effect on performance as a level of speed and precision has to be maintained at all times. Therefore this study was aimed at finding out the effect of the prevalence of cumulative hand trauma disorders faced by pianists.Results: The result of the study carried out showed that 68% of subjects experienced pain in the hand. A majority of 20% of the subjects experienced pain at the site of their wrist. Finkelsteins test was positive in 34% of subjects with pain. The average grip strength taken for males was 37.67 kg's and 20.18 kgs in females. Beighton's scale for hypermobility was taken and 76% of subjects tested positive. Conclusion:In conclusion this study reveals that pianists are predisposed to cumulative hand trauma disorders. With the help of the outcome measure's discussed in the results we are able observe that grip strength is significantly reduced, DeQuervain's is positive and hypermobility does occur in a particularly large amount of the subject population. Using Hoppmann's (1998) pain outcome measure we can conclude that pain does affect the professional performance in a negative way.
