Does aerobic or resistance training improve walking ability in chronic stroke patients?

Funded Activity Summary

The majority of stroke patients discharged from rehabilitation are often housebound. The criterion which most often limits individuals with stroke from achieving 'community ambulation' is the inability to walk long distances. Current views suggest that an exercise program aimed at improving lower limb strength and aerobic fitness will improve walking ability in those stroke patients with mild to moderate disability. However, there are no reported studies that have rigorously investigated whether either of these approaches, singularly or combined, is effective for augmenting walking ability in chronic stroke patients. We will use a randomised, double-blinded controlled trial to determine which of strength training, aerobic training or a combination of the two is the most effective approach for improving walking endurance, measured by the 6-minute walk test, in individuals with mild-to-moderate stroke. In addition, we will determine the benefits of each program to subjects' cardiorespiratory fitness, lower limb strength, mobility and psychological function. Subjects will be randomly allocated to one of 4 groups: 1) Aerobic exercise (and sham strength training); 2); Strength training (and sham aerobic training); 3) Combined strength and aerobic training; and 4) Control (sham strength and aerobic training. Sham treatment for strength training is stretching and calisthenics, and for aerobic exercise is passive motorised cycling. All subjects will attend small group sessions for 10 weeks, with 3 sessions per week, and each session about 1 hour duration. The findings from this study are critical in identifying the most effective and efficient approach to improving stroke patient's walking endurance. Improvement in walking endurance will enable many persons following stroke to achieve the level of 'community ambulation'. Last, it will contribute to the 'evidence-based' scientific framework for treatment of stroke patients.
