Does physical fitness training improve disability after stroke?
There is moderate-quality evidence that physical fitness training improves disability after stroke. Cardiovascular training that includes only aerobic exercise has a moderate effect on disability (standard mean difference [SMD] = 0.52 on a pooled disability scale), although it is not clear whether this effect is sustained after patients stop training.1 (Strength of Recommendation [SOR]: A, based on consistent, good-quality patient-oriented evidence.) There is insufficient evidence to determine whether resistance training has a beneficial effect on disability. Mixed cardiovascular and resistance training has a small effect on disability and is of questionable clinical relevance.1 (SOR: B, based on inconsistent or limited-quality patient-oriented evidence.) There is no evidence of reduced risk of stroke recurrence, nor is there risk of harm from physical fitness training in patients after a stroke.1
Stroke is the fifth most common cause of death and a primary cause of adult disability in the United States.2 Nearly 3% of U.S. adults are stroke survivors.3 Physical fitness levels in these patients are degraded because of the neurologic effects of stroke, tendency for physical inactivity, and predisposing poor baseline fitness.4 Exercise interventions may improve disability and decrease stroke recurrence, but evidence regarding the effect is limited to small trials with diverse functional measures.
This Cochrane review included 58 randomized trials and 2,797 patients.1 Training sessions were diverse in mode, intensity, duration, and proximity to stroke, limiting comparability of results. Some trials included nonambulatory participants, whereas others included only ambulatory patients. Meta-analysis showed no effect on mortality, independence, or stroke recurrence after physical fitness training.
The best evidence of benefit was found for cardiovascular training. Eight
