Relating Ankle Impairments to Walking Ability for Characterization of Sensorimotor Function in Individuals With Chronic Stroke
Shirley Ryan AbilityLab
Summary
The purpose of this study is to capture sensorimotor ankle function in a chronic stroke population through validation of novel, experimental metrics and their comparison with established, clinical measures of function. For this purpose, the researchers will evaluate various single-joint, impairment-level measures such as visuomotor tracking performance and proprioception as well as functional-level measures including spatiotemporal gait (e.g., gait speed and stride length/time) and standardized clinical scales. This study will be carried out in chronic stroke patients as well as age-matched healthy controls. Results will help the researchers identify more quantitative metrics that can be used to monitor and rehabilitate sensorimotor function following stroke.
Description
The purpose of this study is to capture sensorimotor ankle function in a chronic stroke population through validation of novel, experimental metrics and their comparison with established, clinical measures of function. Target populations will perform various single-joint ankle tasks (i.e., dorsiflexion and plantarflexion), assessing the quality of their movements during visuomotor tracking, goal-directed movements and unilateral/bilateral tests of joint position and force sense. Collecting these data will delineate which measures of ankle function are specific to chronic stroke, as well as sen…
