Effects of Whole-body Electrical Muscle Stimulation Exercise on Adults withNeuromuscular Disease
University of Missouri-Columbia
Summary
This single-arm pilot study evaluates the effects of whole-body electrical muscle stimulation (WB-EMS) exercise on neuromuscular and physical function in adults with neuromuscular disease (NMD). Due to motor unit impairments, NMD patients often cannot tolerate traditional exercise. WB-EMS bypasses voluntary activation limits by directly stimulating muscle contractions. Up to 50 adults with conditions like ALS, SMA, and MG will undergo 20-minute supervised WB-EMS sessions (1-2 times weekly for 4-8 weeks) using the Katalyst system. Outcomes include neural excitability (TMS), motor unit behavior (EMG, NCS), functional tests (walk, balance, strength), and patient-reported fatigue, pain, and quality of life. Strict safety monitoring and exclusion criteria are in place. This study will provide preliminary data on WB-EMS as a potential exercise modality for NMD.
Description
This single-arm pilot study aims to investigate the effects of a whole-body electrical muscle stimulation (WB-EMS) exercise program on neuromuscular and physical function in adults with neuromuscular disease (NMD). The background rationale is that individuals with NMD often experience significant barriers to traditional exercise due to impaired voluntary motor unit activation, leading to sedentary behavior, physical deconditioning, and worsened long-term health outcomes. WB-EMS may offer a therapeutic alternative by bypassing voluntary activation limits and directly stimulating muscle contract…
