Background And Purpose:
This pilot study examined the feasibility of a proximal muscle resistance training program to improve walking in people with multiple sclerosis using a combination of in-person, virtual, and independent exercise sessions.
Methods:
People with multiple sclerosis (Expanded Disability Status Scale Score is <6.0) were recruited to a study of resistance training exercises targeting hip abduction and trunk muscles for 10 weeks. Feasibility criteria were: enrolling 40 participants, retaining ≥80%, ≥80% visit adherence, no serious intervention-related adverse events, and ≥80% satisfaction. The 6-Minute Walk Test, Timed 25-Foot Walk Test, muscle performance (hip abduction and lateral trunk flexion strength, and trunk flexion endurance), patient-reported outcomes, daily step count, and pelvis and trunk kinematics were measured before and after intervention. Patient-reported outcomes and step count were measured again 12 weeks after intervention.
Results:
Twenty-eight people (median Expanded Disability Status Scale is 3.5) enrolled and 92.8% were retained. Visit adherence was 86.5% (96% for virtual visits, 74% for in-person visits), and 48% of participants preferred virtual visits, while 20% preferred in-person visits. There were no serious intervention-related adverse events, and there was 100% satisfaction. Following intervention, 6-Minute Walk Test distance increased 29.6 m (95% confidence interval [CI], 12.2-47.0), Timed 25-Foot Walk Test decreased by 0.57 seconds (95% CI, -0.85 to -0.29), and all muscle performance outcomes improved. Patient-reported outcomes also improved immediately following intervention. There were no changes in average daily step count or trunk and pelvis kinematics.
Discussion And Conclusions:
This proximal muscle resistance training program was feasible, with benefits in walking and muscle strength, warranting a future efficacy study.
