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

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

Sponsor

Ankara University

Enrollment

38 participants

Start Date

Apr 24, 2026

Study Type

INTERVENTIONAL

Conditions

Parkinson Disease (PD)

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

Interventions

BEHAVIORALDual-Task Training

Dual-task training will be applied 3 times per week for 8 weeks, with each session lasting 60 minutes. The program combines motor tasks (such as peg placement, object manipulation, bilateral coordination, and mobility tasks) with simultaneous cognitive tasks (such as backward counting, category-based word generation, and memory tasks).
