Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This study aims to investigate the effects of task-oriented upper limb training combined with focal vibration on hand function, proprioception, and muscle tone in patients with stroke. Participants will be randomly assigned to either an experimental group receiving task-oriented training with concurrent focal vibration or a control group receiving task-oriented training alone. The intervention will be conducted over 6 weeks. Outcome measures will be assessed before and after the intervention.

Treatments
Experimental: Task-Oriented Upper Limb Training with Focal Vibration
Participants will receive task-oriented upper limb training combined with focal vibration applied to the wrist extensor muscles during task performance. The intervention will be conducted for 6 weeks, twice per week, with each session lasting 30 minutes. Each session will include functional tasks such as reaching, grasping, object manipulation, and wrist control exercises. Focal vibration will be applied only during active task execution to enhance proprioceptive input, improve hand function, and reduce muscle tone.
Active_comparator: Task-Oriented Upper Limb Training Alone
Participants will receive the same task-oriented upper limb training without focal vibration for 6 weeks, twice per week, with each session lasting 30 minutes. Each session will include functional tasks such as reaching, grasping, object manipulation, and wrist control exercises. The vibration device will be attached to the wrist extensor muscles in the same manner as the experimental group, but no vibration will be applied.
