Although instrument playing-based training has been repeatedly report-ed to improve functional hand movements including grasping, the at-tempts to present quantitative information on physiological mechanism of grasping have been relatively insufficient to determine the type and the intensity of the exercises involved. This study aimed to examine the muscle activation during hand percussion playing depending on the grasping type and the playing tempo. A total of twelve healthy older adults with a mean age of 71.5 yr participated in this study. Surface electrodes were placed on three grasping-related muscles: Flexor digi-torum superficialis, extensor digitorum, and flexor pollicis brevis. Partic-ipants were instructed to play with the egg shaker, paddle drum mallet and clave involving different types of grasp at three different tempi (i.e., 80, 100, and 120 bpm) and sEMG data were collected during each play-ing. Significantly greater muscle activation was generated with the small sphere type of egg shaker, compared to the handle type of paddle drum mallet and the small cylinder type of clave. Playing at faster tempo also elicited significantly greater muscle activation than at slower tem-po. With regard to the rise time of muscle activation, while tempo sig-nificantly affected the rise time, the time to peak muscle activation did not significantly change depending on the grasping type. This study confirmed that grasping pattern and the tempo of movement signifi-cantly influence the muscular activation of grasping involved in instru-ment playing. Based on these results, clinical implication for instrument selection and structured instrument playing would be suggested.
