Musicians suffer from different R.S.I. (Repetitive Strain Injuries) and more than 60% leave their professional career before 50 in the U.S. because of this problem. MusiAct has been designed for some specific needs in musicians’ daily life . With MusiAct, musicians can figure out different music elements such as rhythm and accent while rehabilitating their hand injuries. They listen to music, use their hands to tap or squeeze MusicAct and at the end can see their progress not only in understanding music elements but also in the rehabilitation process.
