Task-Oriented Upper Limb Training With Focal Vibration in Stroke
23 de abril de 2026 actualizado por: Jisu Kim
Effects of Task-Oriented Upper Limb Training With Localized Vibration on Hand Function, Proprioception, and Muscle Tone in Patients With Stroke
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.

Descripción detallada
Stroke often results in impairments in upper limb function, including reduced motor control, altered muscle tone, and deficits in proprioception. These impairments can significantly limit functional use of the affected limb in daily activities.
Task-oriented training has been widely used in stroke rehabilitation to improve motor function through repetitive and goal-directed tasks. However, recovery may be limited when sensory input is insufficient. Enhancing sensory feedback, particularly proprioceptive input, may facilitate sensorimotor integration and improve functional outcomes.
Focal vibration applied to muscle or tendon has been shown to stimulate muscle spindle afferents, thereby enhancing proprioceptive input to the central nervous system. When applied during active task performance, focal vibration may further augment motor learning and functional recovery.
This study is designed as a randomized controlled trial to investigate the effects of task-oriented upper limb training combined with focal vibration. Participants will be randomly assigned to either an experimental group receiving task-oriented training with concurrent focal vibration applied to wrist extensor muscles or a control group receiving task-oriented training alone.
The intervention will be conducted for 6 weeks. Outcome measures will include upper limb motor function, proprioception, manual dexterity, and muscle tone, assessed before and after the intervention.
The findings of this study may provide evidence for the effectiveness of combining focal vibration with task-oriented training to enhance upper limb recovery in patients with stroke.

Intervención / Tratamiento |
|---|---|
|
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.
|
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.
|
|
Comparador activo: 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.
|
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.
