Description

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.

Interventions

Task-oriented upper limb training combined with focal vibration (Procedure)
Participants in the experimental group will receive task-oriented upper limb training combined with focal vibration applied to the wrist extensor muscles during task performance. The intervention will be administered for 30 minutes per session, 2 times per week, for 6 weeks, and no vibration will be applied during rest periods.
Active Comparator: Task-Oriented Upper Limb Training Alone (Procedure)
Participants in the control group will receive task-oriented upper limb training without the application of focal vibration, with the device attached to the wrist extensor muscles. The intervention will be administered for 30 minutes per session, 2 times per week, for 6 weeks.

Eligibility criteria

Inclusion Criteria: * Individuals diagnosed with stroke at least 3 months prior * Individuals with sufficient cognitive function (Mini-Mental State Examination \[MMSE\] score ≥ 24) * Individuals able to maintain a seated position independently and perform upper limb functional tasks (Trunk Control Test \[TCT\] ≥ 50) * Individuals with muscle tone of the affected upper limb of Modified Ashworth Scale (MAS) Grade ≤ 2 * Individuals with Fugl-Meyer Assessment-Upper Extremity (FMA-UE) scores between 20 and 50 * Individuals able to grasp and move objects with the affected upper limb and with muscle strength of Manual Muscle Test (MMT) Grade ≥ 3 * Individuals with impaired proprioception in the affected hand (defined as a score \< 2 on the wrist or thumb position item of the FMA-UE) Exclusion Criteria: * Individuals within 3 months after stroke onset * Individuals with fractures, severe soft tissue injuries, or contraindications to focal vibration * Individuals with severe sensory hypersensitivity or complex regional pain syndrome (CRPS) * Individuals who received treatments affecting upper limb function within the past 3 months (e.g., botulinum toxin injection, surgery, nerve block)
