A recent systematic literature review by physiotherapists in Brazil and Australia has identified 15 trials involving 673 people who could walk after a stroke. Data from these randomised trials were pooled to determine the overall effects of treadmill training after stroke.
Among people who can walk after stroke, treadmill training improves their walking speed and distance. Specifically, treadmill walking increased walking speed by 0.13 m/s (95% CI 0.08 to 0.19) and distance by 46 m (95% CI 24 to 68) compared with no/non-walking intervention; these effects were largely maintained beyond the intervention. Among people who can walk after stroke, the effect of treadmill walking is the same as or better than the effect of overground walking training for improving walking speed and distance.
