Parkinson's disease (PD) is considered an age-related neurologic disorder that causes motor and non-motor disabilities. Patients with PD present different motor characteristics including bradykinesia, reducing muscular strength, weaker motor and postural control, abnormal range of motion and joint torque, and greater variability during movement. These features cause difficulties in patients' activities of daily living and also bring higher fall risks when they do transferred movements, such as sit-to-stand (STS). The purpose of this study was to consider if Patterned Sensory Enhancement (PSE), a neurologic music therapy (NMT) technique might impact sit-to-stand movement with people with PD. Data were collected on fifteen participants who completed sit-to-stand exercises in baseline, PSE music, and no music conditions. Each sit-to-stand movement was divided into three phases: standing, balance, and sitting. Movements were analyzed for duration/time of movements, sum of movement acceleration (standard deviations) of x, y, and z, pitch of movements, and rotation rate (in z). Significant differences were found in sum of acceleration of x, y, and z in all three phases, with means that participants showed less postural control under PSE music condition. Another significant difference was found in fluctuations of the rotation rate (in z) in the sitting phase, with means indicating participants presented less postural control under PSE music condition compared to no music condition. No other significant differences were found. These results are contrary to prior findings and more research is needed to determine the influence of PSE on STS movements.
