Exercise in neuromuscular disease.
In the past, patients with neuromuscular diseases were advised not to exercise because of the fear that too much exercise might produce "overuse weakness." No controlled studies have demonstrated that the phenomenon of overuse weakness actually exists. Most studies of exercise training in patients with neuromuscular disease, despite methodologic limitations, suggest that strength and aerobic capacity gains can occur in patients with slowly progressive disorders. Four forms of exercise training are relevant to patients with neuromuscular disorders: flexibility, strengthening, aerobic, and balance exercises. The literature regarding these forms of exercise in patients with neuromuscular disorders is summarized in this article, and recommendations are made regarding the direction future research on exercise in this population should take.
