Jump assessment on a force plate—an approach to quantify subtle lower limb neuromuscular deficits in people with multiple sclerosis

Neuromuscular impairments are common in people with multiple sclerosis (pwMS), often beginning subclinically in early disease stages and contributing to long-term disability. Traditional clinical tools such as the Expanded Disability Status Scale (EDSS), however, lack sensitivity for detecting subtle neuromuscular dysfunction. In recent years, jump assessment has emerged as a digital, performance-based approach to evaluate lower-limb neuromuscular function in pwMS. Vertical jump tests on a force
