Effect of Metronome-Based Structured Rhythmic Exercise Program on Freezing and Gait Parameters in Parkinson Disease

"Sample size was determined via G\*Power analysis: two groups (n=13 each), total n=26. Participants will be randomized using Random.org into the Rhythmic Exercise Group (REG) or the Exercise Group (EG).~Both groups will receive a supervised home-based exercise program, overseen via telerehabilitation. Exercises will be performed 3 times per week for 45-60 minutes each session, over 4 weeks (12 sessions total). Progression to the next week's program will require an 80% success rate; otherwise, the same week's program will be repeated. Online supervision will monitor weekly performance."
