Hip exoskeleton could help stroke patients put a spring in their step
Researchers are developing a robotic exoskeleton platform that could overcome the limitations of treadmills used during the rehabilitation of the many stroke survivors who have problems walking.
More than 80% of stroke patients can lose normal function in one leg, which affects their natural gait, increasing the risk of falling and preventing them from engaging in certain activities – perhaps leading to a more sedentary lifestyle and its associated health issues. Inspired by the success of split-belt treadmills, the team has managed develop a hip exoskeleton system that mimics the actions of side-by-side belts moving at different speeds to amplify gait asymmetry to enhance motor learning. It was tested on just over a dozen healthy volunteers, with the team finding that the device "elicited adaptation in spatiotemporal and kinetic gait measures similar to split-belt treadmill training."
