Perturbation-based balance training


Many people, like older adults and individuals with stroke, are increased risk for falls. Physical exercise can prevent falls in older adults, but no exercise program has effectively reduced fall risk among individuals with stroke. In order to keep from falling down, individuals must often perform rapid and sophisticated reactions. This work explores novel training techniques in order to retrain these rapid reactions. This work will provide essential information about the possibility of training rapid balance reactions within several populations, including those with stroke. We anticipate that this training has the potential to not only prevent falls, but to also improve safe independent mobility and engagement in daily activities.
