This study explored the therapeutic effects of a drum set playing intervention on motor and psychosocial functions in individuals with Parkinson's disease (PD). Three participants engaged in ten individualized sessions over six weeks, targeting limb coordination and motor control. Pre- and post-assessments included motor, cognitive, and psychosocial measures, alongside qualitative interviews. Results indicated improvements in synchronization, balance, attention, and emotional well-being. Participants also reported increased confidence and functional use of limbs in daily life. The findings suggest that drum set playing may serve as an effective, multidimensional intervention within music therapy for individuals with PD.
