Brief Summary
The purpose of this proposal is to use novel video-based movement tracking technology to measure gait quality after stroke - in the home. Current rehabilitation practice assesses walking in the highly controlled 'ideal' clinical environment. The implicit assumption by clinicians and researchers is that the way people walk in the clinic (their best capacity) reflects the way they walk in the real-world (true performance). With advances in computer vision and development of pose estimation algorithms, it is now possible to directly measure how people are walking in their homes. It is critical that researchers apply this technology to examine the basic assumptions that underlie current rehabilitation practice. Here, a video-based pose estimation workflow will be used to 1) contrast the gait patterns of persons post-stroke as observed in-clinical vs. in-home settings, and 2) map the rate of deterioration of clinically-derived walking improvements, in the home. This methodology has been used to accurately measure gait kinematics in people with stroke as they walk in laboratory, however this study now seeks to use these methods to record people with stroke as they walk in their natural home environments. The ultimate outcome of this project will not only be freely-available video-based workflow modified for home-based gait assessments, but also preliminary data revealing how people with stroke walk in the real world.

Outcome Measures
Primary Outcomes (3)
Change in step length symmetry
The normalized difference between short step length and long step length; a spatial parameter (short step length - long step length / short step length + long step length) Will be compared across timepoints.
In-clinic baseline (day 1), in-home baseline (day 1), during training (day 2), same day transfer assessment (day 2), 1-day transfer assessment (day 3), 3-day transfer assessment (day 5), 1-week transfer assessment (day 9)
Change in step time symmetry
The difference between short step time and long step time; a temporal parameter (short step time- long step time) Will be compared across timepoints.
In-clinic baseline (day 1), in-home baseline (day 1), during training (day 2), same day transfer assessment (day 2), 1-day transfer assessment (day 3), 3-day transfer assessment (day 5), 1-week transfer assessment (day 9)
Change in self selected gait speed
The speed at which a participant is walking (meters/second) Will be compared across timepoints.
In-clinic baseline (day 1), in-home baseline (day 1), during training (day 2), same day transfer assessment (day 2), 1-day transfer assessment (day 3), 3-day transfer assessment (day 5), 1-week transfer assessment (day 9)

Study Arms (1)
Individuals with Stroke
EXPERIMENTALIn this single group, proof-of-principle design, all eligible participants will be assigned to a single group. These are individuals with stroke who meet inclusion and exclusion criteria. They will each undergo the same assessments and participate in a single walking training session.
Interventions
Participants will engage in four, five-minute periods of step symmetry training during session 2. This training uses established sensorimotor adaptation-based methods (e.g. split-belt treadmill walking, walking with unilateral leg weighting) to elicit motor aftereffects of more equal step lengths. Two minute sitting rest breaks will be given between training blocks or at the participant's request. A video recording will be taken of the first and final two minutes of training.
Eligibility Criteria
You may qualify if:
- stroke \>6 months prior
- hemiparetic gait pattern with step length difference of 4cm or greater
- able to ambulate whiteout physical assistance from another person (use of an assistive device are acceptable), gait speed \>/= 0.2m/s
- normal or corrected-to-normal vision
You may not qualify if:
- neurological condition other than stroke
- aphasia limiting comprehension of task instructions pregnancy
- uncontrolled hypertension (\> 150/90 mmHg at rest)
- dementia, cognitive impairments, or psychiatric disorders limiting the ability to provide informed consent
- epilepsy
- orthopedic or pain conditions limiting walking
- concurrent engagement in physical therapy or other research study.
