Progressive Muscular Atrophy

The purpose of the Clinical Procedures To Support Research (CAPTURE) study is to utilize information collected in the medical record to learn more about a disease called amyotrophic lateral sclerosis (ALS) and related disorders.

CAPTURE ALS is a long-term data and biorepository platform that will facilitate future ALS research. CAPTURE ALS will provide the standardized systems and tools necessary to collect, store, and analyze vast amounts of multimodal information about ALS. These multimodal datasets and biosamples will be made available for use by researchers or industry across Canada and around the world in accordance with the CAPTURE ALS Data Sharing Policy to advance research on ALS.

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.
