[Purpose] The purpose of this study was to examine the immediate effects of therapeutic
keyboard music playing on the finger function of subjects’ hands through measurements of
the joint position error test, surface electromyography, probe reaction time, and writing
time. [Subjects and Methods] Ten subjects were divided randomly into experimental and
control groups. The experimental group used therapeutic keyboard music playing and the
control group used grip training. All subjects were assessed and evaluated by the joint
position error test, surface electromyography, probe reaction time, and writing time.
[Results] After accomplishing therapeutic keyboard music playing and grip training,
surface electromyography of the two groups showed no significant change, but joint
position error test, probe reaction time, and writing time obviously improved.
[Conclusion] These results suggest that therapeutic keyboard music playing is an effective
and novel treatment for improving joint position error test scores, probe reaction time,
and writing time, and it should be promoted widely in clinics.
