To determine changes in power symmetry, gait symmetry, and functional outcomes for participants' poststroke (Inpatient Rehabilitation Facility) after participating in an intervention using a recumbent cycle with power biofeedback (BFB). To determine how this intervention can impact gait asymmetry, a common disorder poststroke secondary to hemiparesis. Gait asymmetry is a difficult impairment to treat because it is difficult for both therapists and patients to perceive. Training with BFB allows for quantitative data about the power production or lack of that directly impacts safety in walking, increased energy expenditure, and decreased gait speed.
Specific Aim 1 will determine the change in cycling power using BFB on a group of participants with stroke in an Inpatient Rehabilitation Facility. Specific Aim 2 will determine the effect size of the change in gait symmetry with cycling training with power BFB pre- to post-cycle intervention. Specific Aim 3 will determine the effect size of the change in functional mobility with cycling training with power BFB pre- to post-cycle intervention. Understanding the impact of cycle training with power BFB is an important step in improving stroke rehabilitation. This study is significant because it…

Traditional rehabilitation course will occur.
Individuals will receive biofeedback about their power production and power symmetry while participating in a 32 minute recumbent cycling session in inpatient rehabilitation facility.
