Effects of Power and High-Intensity Gait Training for Functional Mobility an Ambulation in Chronic Stroke

Summary

This randomized controlled trial aims to determine the combined effect of power training and high-intensity gait training on functional mobility and locomotion following chronic stroke.

Conditions

• Stroke

Interventions

OTHER

power training + high-intensity gait training

This group will be given a combined program that comprises gait training and lower-limb power training, which will take place three times a week. The gait component will consist of overground walking at increased intensity and treadmill training whilst using a safety harness. At the initial stage, treadmill (1.5-2.0 mph) for a duration of 2 sets,3 minutes, and 10-minute overground moderate-intensity walking is offered with frequent rests. The intensity will be gradually increased throughout the program, with an increase in speeds on the treadmill to 2.0 mph (2.5 mph or 3.0 mph) (two sets of three minutes, then three sets of 3-4 minutes, and finally 5-10 minutes at moderate and high intensity) and overground walking (10-15 min to up to 20 min at high intensity).

OTHER

power training

Individuals in the power training group will also train three times a week, including lower-limb resistance and functional strength work, applying a focus on explosive concentric effort. The exercise will consist of 3 sets (or 6 repetitions of stepping backward over a hurdle, warming up in sitting knee extension with resistance band, marching in a seat with a load on the ankle, transferring sit to stand, and hopping up on the box 46 inch). The number of sets will be increased as they are tolerated, beginning with 3 sets to 4 sets and ultimately up to 5 sets of each exercise as tolerated as the training progresses. The intensity will be progressed by raising the resistance ( box height) and performance speed.

OTHER

high-intensity gait training

The members of this group will receive high-intensity gait training three days per week, taking into consideration both treadmill gait in a safety harness and overground gait. Initial training will start with a treadmill speed of 1.5 2.0 mph, two sets/3 minutes each, and 15 minutes overground walking at moderate intensity, and rest breaks when necessary. The progression will entail a gradual increase in the speeds on the treadmill to 2.0-2.5 mph (three sets of 3 minutes) and subsequently to 2.5 3.0 mph (three sets of 3 4 minutes) with the overground walking time extended to 15-20 mins and subsequently to 20 minutes at greater intensities.
