Introduction: Multiple sclerosis is associated with motor impairments and walking limitations that compromise functional autonomy, with limited evidence on accessible strength-based interventions specifically targeting ambulation.
Objective: To evaluate the effects of an elastic resistance training program on both objective and perceived walking performance in people with multiple sclerosis.
Methodology: A 12-week randomized controlled pilot trial was conducted with 21 participants with multiple sclerosis (experimental group, n = 12; control group, n = 9). The experimental group performed a progressive elastic resistance training program (2-3 sessions/week); the control group maintained their usual activities. Walking performance was assessed at baseline and at 4, 8, and 12 weeks using the T25FW and the MSWS-12 scale.
Results: Both groups showed baseline homogeneity (mean age: 49.7 ± 10.45 years; EDSS: 4.19 ± 1.48). In the experimental group, T25FW time decreased in a clinically significant manner from 8.1 s (95% CI: 6.9–9.2) at PRE to 5.6 s (95% CI: 4.7–6.5) at POST, with no overlap between the confidence intervals. Likewise, a clear improving trend was observed in the subjective perception of walking (MSWS-12: from 34.6% to 25.9%). In contrast, the control group did not show statistically significant changes in either variable.
Discussion: The findings support the potential of elastic resistance training as an accessible intervention to improve walking in multiple sclerosis.
Conclusions: Elastic strength training improves walking performance and represents an effective, safe, and low-cost strategy in the training of people with multiple sclerosis.
