Abstract: To investigate claims that painful musculoligamentous overuse in the arms and hands of pianists is accompanied by loss of motor control, we studied 18 pianists with overuse syndrome of one or both arms and hands and 22 skill-matched pianists with no history of overuse. All of the pianists performed continuous repetitions of a five-finger exercise on a piano keyboard at metronome-paced tempos. The main outcome measures were quantitative analysis of four measurements of performance (duration of key presses, interval between key presses, velocity of key presses [loudness], and time off the metronome beat [difference between actual and expected time of key press]); comparison of the errors in the two groups; and comparison of the performances by a listening panel. The two groups had significant differences in performance, and a classification tree had a sensitivity of 0.886 and a specificity of 0.862 in identifying the affected hands. The pianists with overuse syndrome made more skill-based errors. The listening panel could distinguish between the affected and unaffected hands. We conclude that pianists with overuse syndrome have a coordination disturbance.
