Effects of Vibration Stimulation Combined With Task-oriented Training on Hand Motor Function in Chronic Stroke

Effects of Vibration Stimulation Combined With Task-oriented Training on Hand Motor Function in Chronic Stroke: a Case Series Study

There is a lack of effective therapies for hand and finger function recovery in people with chronic stroke. This study assessed the effects of combining vibration stimulation with task-oriented training on functional recovery, and treatment persistence. Participants with chronic stroke underwent 24 sessions of vibration stimulation combined with task-oriented training over 12 weeks, in addition to regular therapy. Functional recovery was assessed using the Fugl-Meyer assessment for motor function (FMA-wrist and hand), the Box and Blocks Test (BBT) for hand dexterity, and the Motor Activity Log (MAL) for daily functional activities. Minimal detectable change (MDC) and minimal important difference (MID) criteria were applied to interpret changes in assessment scores.
