Feasibility, Preliminary Efficacy, and User Perspective Usability of Wearable Focal Vibration Therapy on Upper Extremity Function of People With Multiple Sclerosis: A Pilot Study
This pilot mixed-method study will evaluate the feasibility, preliminary efficacy, and user experience of a home-based wearable Focal Vibration Therapy (FVT) intervention for improving upper extremity (UEx) function in people with multiple sclerosis (MS). Fifteen adults with relapsing-remitting MS (PRMS) and self-reported UEx impairments will participate in a 4-week FVT program using MyovoltTM wearable FVT devices applied to arm muscles.
• Aged over 18 years
• Confirmed diagnosis of RRMS according to the McDonald criteria (33)
• No MS relapse or exacerbation within the past 6 months (ensuring stability of symptoms)
• Self-report on clinical evidence of UEx impairment (including reduced arm/hand function, muscle weakness, spasticity, or pain).
• Stable on MS treatment for at least four weeks before recruitment, with no plans to initiate new treatments (participants may continue current treatments during the study)
• Agree and are able to use the FVT device after training.
• Sufficient proficiency in English to participate in interviews and follow instructions
• Able to visit the laboratory for assessments
• Able to provide written informed consent
