Abstract

This study investigates the use of multi-field electrostimulation with the Fesia Grasp device for hand rehabilitation in patients with Multiple Sclerosis (MS). This research aims to evaluate the effectiveness of this novel approach in improving hand function and dexterity in MS patients. A cohort of MS patients with varying degrees of hand impairment underwent a structured rehabilitation program using the Fesia Grasp device, which delivers targeted electrical stimulation to specific muscle groups. Outcome measures assessed multiple aspects of hand function, including gross and fine motor skills, strength, and functional independence, at baseline, post-intervention, and 1-month follow-up. The main finding was a sustained between-group improvement in gross manual dexterity, measured by the Box and Block Test, at 1-month follow-up (p = 0.008, eta 2p = 0.429). Secondary analyses showed task-specific gains in the experimental group, with significant intragroup improvements in Jebsen-Taylor Hand Function Test items related to simulated feeding (p = 0.012) and lifting light objects (p = 0.036), and a trend toward better performance in stacking checkers (p = 0.069) and faster page-turning (p = 0.046) after the intervention. Other outcomes showed non-significant changes favoring the experimental group. This research contributes to the growing body of evidence supporting the use of advanced electrostimulation techniques in neurological rehabilitation and offers promising implications for enhancing the quality of life for individuals with MS-related hand dysfunction.
