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\u002Ftime) 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.",[61],"Stroke",[63,64,65,66,67],"Robotic Rehabilitation","Sensorimotor function","Proprioception","Motor Control","Ankle Rehabilitation","NOT_YET_RECRUITING","2025-05-21",{"date":71,"type":72},"2025-05-25","ACTUAL",{"date":74,"type":57},"2025-07-15",{"date":76,"type":57},"2027-08-31",{"name":5,"class":6},1]
