Feasibility, Preliminary Efficacy, and User Perspective Usability of Wearable Focal Vibration Therapy on Upper Extremity Function of People With Multiple Sclerosis: A Pilot Study
University of Florida
Summary
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.
Eligibility

- Healthy volunteers
- No
Inclusion Criteria: * 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…
Interventions
- Devicewearable focal vibration therapy
The focal vibration intervention will be delivered using a modified MyoVolt wearable vibration therapy device. Each MyoVolt vibration device will be assigned to a single participant for individual use only and will be clearly labeled with a unique study ID. Devices will be distributed during the baseline training session and returned at the end of the study. To prevent unauthorized use: * Participants will receive training on the appropriate use and safe handling of the device. * Each device will be stored by the participant in their home in a designated area, along with written instructions and contact information in case of any issues. * The device operates only via a linked smartphone app. This will restrict unauthorized users from easily accessing or operating the device. * Participants will be instructed not to allow others to use the device and to report any device malfunction, loss, or suspected misuse immediately to the research team.
