Evaluating muscle function and fatigue in multiple sclerosis patients

Non-invasive Evaluation of Muscle Oxidative Capacity. Study of Its Relationship With Muscular Endurance and Fatigue in Patients With Multiple Sclerosis

Observational University Hospital, Clermont-Ferrand · NCT06083194

This study is testing if better muscle oxygen levels can help people with multiple sclerosis have more endurance and less fatigue over six months.

What this trial studies

This observational study aims to assess the relationship between muscle oxidative capacity and muscular endurance in patients with multiple sclerosis (MS). Using near-infrared spectroscopy (NIRS), the study will measure muscle oxygenation and calculate maximal muscle oxidative capacity (mVO2) through non-invasive methods. The investigators hypothesize that higher mVO2 correlates with better muscular endurance and lower fatigue levels. Participants will be monitored over a six-month period to evaluate changes in these parameters.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with multiple sclerosis who have a specific disability status and meet certain health criteria.

Not a fit: Patients with severe psychiatric conditions or unstable cardiovascular diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of fatigue and endurance in multiple sclerosis patients.

How similar studies have performed: Previous studies have shown mixed results regarding muscle oxidative capacity in MS, indicating that this approach is both relevant and necessary for further exploration.
