Comparison of Three Balance Training Protocols for Individuals Post Stroke

The purpose of this study is to compare conventional balance training to reactive training and to a novel, high intensity, harnessed training program. This study examines the impact of these interventions on fall risk and on a range of important aspects of balance including overall mobility, quality of life, and health. Participants will be 60-69 adults who had a stroke more than 6 months ago and who ambulate independently. Each participant will complete 14 sessions consisting of 4 (2 pre-, 2 post-) testing sessions and 10 intervention sessions. The pre and post testing will be the same and will consist of clinical and survey based balance and quality of life assessments and treadmill based perturbed gait testing. The pretest will be sessions 1 and 2 will be followed by 10 intervention sessions. There will be 3 treatment groups: a conventional balance training group (PT), a reactive slip training group (Slip), and a multidirectional harness group (MHG). Participants will be randomly assigned to a group following screening and consent. The conventional balance training group (PT) will receive 10 sessions of individualized standard of care physical therapy with the goal of improving balance and mobility. The only instructions to the PT are that the focus of the course of care should be on "balance and mobility" and that there should be 10 sessions. The reactive slip training group (Slip) will complete a standing slip session using the current protocol of scaling slip distance and force to each individual and modulating the slip intensity across the session based on subject responses. The remaining nine intervention sessions will consist of accompanied walking for up to 45 minutes. Participants will walk at a comfortable pace while accompanied by a researcher. The multidirectional harness group (MHG) will use a harness that allows movement in all directions, playing selected Kinect™ active video games with varied balance demands, on multiple balance training surfac
