Therapeutic Exercise for Amyotrophic Lateral Sclerosis (ALS)

Strengthening exercises may improve function in people with amyotrophic lateral sclerosis (ALS). Level of evidence: "C"

A Cochrane review [Abstract] 1 included 2 studies. The first examined the effects of a twice-daily exercise program of moderate load, endurance exercise versus "usual activities" in 25 people with ALS. The second examined the effects of thrice weekly moderate load and moderate intensity resistance exercises compared to usual care (stretching exercises) in 27 people with ALS. After three months, when the results of the two trials were combined, there was a significant weighted mean improvement in the Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS) measure of function in the exercise compared with the control groups (3.21, 95% confidence interval 0.46 to 5.96) in favour of the exercise group. No statistically significant differences in quality of life, fatigue or muscle strength were found.

Comment: The quality of evidence is downgraded by imprecise results (limited study size for each comparison) and by inconsistency (heterogeneity in interventions).
