Summary
Eight weeks of lower-body resistance training improved walking mechanics and functional ability in individuals with multiple sclerosis (MS). This intervention enhanced gait parameters and reduced fatigue, suggesting resistance exercise is beneficial for MS patients.
Area of Science:
- Neurology
- Rehabilitation Science
- Exercise Physiology
Background:
- Multiple sclerosis (MS) is a chronic neurological disease impacting mobility and functional independence.
- Impaired walking mechanics are a significant challenge for individuals with MS, affecting their quality of life.
- Resistance training is a potential therapeutic strategy to address functional deficits in MS.
Purpose of the Study:
- To investigate the effects of an 8-week lower-body resistance-training program on the walking mechanics of individuals with MS.
- To assess changes in gait kinematics, strength, fatigue, and self-reported disability following the intervention.
Main Methods:
- A repeated-measures design was employed, with gait analysis conducted before and after an 8-week progressive resistance-training program.
- Eight ambulatory participants with MS (Expanded Disability Status Scale 2.5-5.5) underwent training using conventional resistance equipment.
- Key outcome measures included kinematic gait parameters (e.g., knee range of motion, stance/swing/double-support phases, step/stride length, velocity, toe clearance), isometric strength, 3-minute stepping test, fatigue indices, and self-reported disability.
Main Results:
- Significant improvements were observed in the percentage of stride time in swing phase, step length, stride length, and foot angle.
- Significant reductions were noted in the percentage of stride time in stance and double-support phases, duration of double-support, and toe clearance.
- Isometric leg strength increased in two muscle groups, fatigue indices decreased, and the 3-minute stepping test performance improved by 8.7%.
Conclusions:
- An 8-week lower-body resistance-training program effectively improved walking mechanics in individuals with moderate MS-related disability.
- The findings suggest that resistance training is a viable intervention for enhancing walking ability and functional capacity in this population.
- Further research can explore long-term effects and optimal resistance training protocols for individuals with MS.
