Effects of Dual-Task Training on Upper Extremity Function in Parkinson's Disease

Summary

The goal of this clinical trial is to investigate the effects of dual-task training on upper extremity function and muscle thickness in individuals with Parkinson's disease. The main questions it aims to answer are: Does dual-task training improve upper extremity function in individuals with Parkinson's disease? Does dual-task training lead to changes in upper extremity muscle thickness measured by ultrasonography? Researchers will compare a dual-task training group with a control group receiving routine care to determine whether 8 weeks of dual-task training results in greater improvements in upper extremity outco Participants will: complete baseline and post-intervention assessments of upper extremity function, muscle thickness, grip strength, and pinch strength be assigned to either a control group or a dual-task training group receive dual-task training 3 days per week for 8 weeks if assigned to the intervention group
