Filter by:The purpose of this study is to examine the reflex excitability of the rectus femoris in individuals with and without post-stroke Stiff-Knee gait. We use electrical stimulation of the peripheral nerve innervating the rectus femoris for a well-controlled reflex stimulus. We are investigating whether reflex excitability of the rectus femoris correlates with gait kinematics.
Difficulty walking is common after a stroke. Although physical rehabilitation helps a little with the improvement of walking ability, recovery is usually incomplete. The purpose of this study is to explore how two different treadmill training approaches influence walking speed, symmetry, and balance in people with chronic severe stroke-related walking impairment. The two approaches involve either forward or backwards treadmill training. This study will look at changes in walking performance and balance, before and after training. This study may lead to more efficient methods for improving walking performance and balance after stroke.
In this research study, the investigators aim to test the usability and efficacy of the GaitBetter system for gait rehabilitation after stroke.
Participants are being asked to participate in a research study conducted by Shih-Chiao Tseng, PT, Ph.D. at Texas Woman's University. This research study is to determine whether low-intensive brain stimulation can enhance learning of a leg movement task. The investigators also want to know if brain stimulation can improve the nerve function and walking performance. Our goal is to understand any relationship between brain stimulation and overall movement control improvement. Participants have been invited to join this research if they have had a stroke before or they are healthy adults aged 21 years or older. Research evidence shows stroke can induce permanent brain damage and therefore may cause a person to have trouble learning a new task. This in turn may significantly impact the recovery of motor function in stroke survivors. In addition, the investigators also want to know how a healthy person learns this new leg task and see if her/his learning pattern differs from a stroke survivor. This study comprises two phases: Phase I study investigates short-term effects of brain stimulation on leg skill learning and only requires two visits to TWU. The total time commitment for Phase I study will be about 6.5 hours, 3.5 hours on the first visit and three hours on the second visit; Phase II study is an expanded version of Phase I study to investigate long-term effects of brain stimulation on leg skill learning and requires to complete 12 visits of exercise training paired with brain stimulation over a four-week period and additional one visit for follow-up test. The total time commitment for Phase II study will be about 20 hours, a total of 18 hours for 12 exercise training sessions and two hours for a follow-up test. The investigators hypothesize that people with chronic stroke will show a slower rate of acquiring this leg skill as compared to healthy adults. The investigators also hypothesize that co-applying brain stimulation with 12 sessions of exercise training will enhance skill learning of this leg task for people with chronic stroke and this 12-session exercise program may exert beneficial influences on the nerve function and leg muscle activation, and consequentially improve motor control for walking.
This study will conduct a preliminary evaluation of and obtain user data on a novel game-based visual interface for stroke gait training. Study participants will complete one session comprising exposure to gait biofeedback systems in an order determined by randomization. Participants will be exposed to 2 types of biofeedback interfaces: - newly developed game-based interface (projector screen display) - traditional, non-game interface
