Detaljert beskrivelse
This single-center, prospective, randomized, controlled, parallel-group trial aims to investigate the neurophysiological effects of focal muscle vibration (FMV) delivered via a wearable device. The study will enroll 28 participants (14 per arm, accounting for 20% attrition) diagnosed with unilateral hemiplegia in the subacute stage (3 to 6 months post-stroke). Inclusion requires a Fugl-Meyer Assessment for Upper Extremity (FMA-UE) score between 20 and 50 and a Modified Ashworth Scale (MAS) score indicating mild to moderate spasticity. Exclusion criteria include fixed contractures, severe sensory loss, or other neurological diseases.
Intervention Protocol: Both groups will receive a 45-minute conventional physiotherapy session focusing on range of motion, strengthening, and functional task training, three times per week for 8 weeks. The experimental group (Group A) will additionally wear a portable vibratory device (frequency: 100-120 Hz) on the belly of the affected biceps and forearm extensors for 30 minutes during the therapy session. The device will be applied by a trained physiotherapist. The control group (Group B) receives the same conventional therapy without the vibratory device. Electrical Muscle Stimulation (EMS) will be used as a baseline warm-up for both groups.
Outcomes: The primary outcomes are changes in spasticity (MAS) and motor function (FMA-UE). The secondary outcome is functional independence measured by the Barthel Index. Assessments occur at baseline (Week 0) and post-intervention (Week 8). Data will be analyzed using an intention-to-treat analysis in SPSS v20.

Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Wearable Vibration + Physiotherapy
Participants receive conventional physiotherapy (45 min) plus a wearable vibratory device applied to the affected upper limb for 30 minutes during the session.
Sessions occur 3 times/week for 8 weeks.
|
A portable, battery-operated device worn on the forearm.
It delivers high-frequency focal vibration (100-120 Hz) to the muscle belly (biceps/forearm extensors) to reduce spasticity and facilitate motor recruitment.
|
|
Aktiv komparator: Conventional Physiotherapy Only
Participants receive conventional physiotherapy (45 min) without the vibratory device.
Sessions occur 3 times/week for 8 weeks.
|
A portable, battery-operated device worn on the forearm.
It delivers high-frequency focal vibration (100-120 Hz) to the muscle belly (biceps/forearm extensors) to reduce spasticity and facilitate motor recruitment.
