PROBLEM STATEMENT: Engagement in musical activities has been found to improve symptoms in individuals with Parkinson's disease (PD), and physical therapy and music therapy have been demonstrated as viable non-pharmacological intervention methods that improve motor function in these individuals. Therapeutic instrumental music performance has the attributes of physical, rhythmic and social engagement combined with immediate auditory feedback, and has the potential to bring in additional neuro-rehabilitative effects associated with musical engagement into a treatment design. However, until now, much of the research has focused on the rhythmic aspects of music. Few studies have examined how active and complex engagement with music, such as learning to play an instrument, may help PD patients. Finger-style guitar instruction has the potential to improve bilateral dexterity in addition to other gains reported with music-based interventions in patients with PD.
