Endurance exercise improves walking distance in MS patients with fatigue

Area of Science:

• Neurology
• Rehabilitation Medicine
• Exercise Physiology

Background:

• Multiple Sclerosis (MS) is a chronic neurological disease often associated with motor fatigue.
• Fatigue significantly impacts the quality of life and functional capacity of MS patients.
• Understanding the efficacy of different exercise interventions is crucial for managing MS symptoms.

Purpose of the Study:

• To investigate the effects of endurance training on motor fatigue and functional outcomes in patients with Multiple Sclerosis.
• To compare the impact of endurance exercise versus a control treatment on walking distance and self-reported fatigue levels.

Main Methods:

• Thirty Multiple Sclerosis patients with fatigue and low to moderate disabilities were randomly assigned to either an endurance exercise group or a control group.
• The intervention group performed 45-minute endurance exercise sessions thrice weekly for 3 weeks.
• The control group underwent stretching, balance, and coordination training for the same duration.

Main Results:

• The endurance exercise group demonstrated a significant increase in maximal walking distance, averaging an improvement of 650 meters.
• The control group showed a modest increase in walking distance of 96 meters.
• Despite the gains in walking distance, no significant improvements were observed in fatigue impact, depression, or quality of life scores.

Conclusions:

• Endurance training is effective in enhancing maximal walking distance in Multiple Sclerosis patients.
• The observed improvements in walking distance did not correlate with reductions in subjective fatigue, depression, or quality of life.
• Further research is needed to explore exercise modalities that can positively impact the multifaceted aspects of fatigue in MS.
