Background: Sensorimotor dysfunction such as muscle weakness, impaired sensation, changes in muscle tone, reduced movement control are common in stroke patients. Locomotion function requires continuous afferent sensory input. Impairment of sensory function can hinder the ability to recruit muscles during walking. Patients generally walk slowly, cadence, step and stride length are shorter and the double phase of support increases. Goal: Analyzing the correlation between the propioceptive function of the knee joint and walking speed in post-stroke patients, who are treated at the PMR Outpatient Clinic of Dr. Soetomo General Academic Hospital Surabaya. Methode: An observational analytic cross sectional study, nine subjects measured walking speed (10MWT), joint position sense (JPS) and threshold to detetction of passive motion (TTDPM) of the knee joint, in the period March -November 2020.. Results: There is a moderate correlation between 10MWT and JPS 15 0 on the non-paretic side (r 0.676; p=0.045) and JPS 30 0 on the paretic side (r 0.668; p=0.049). And there is a strong correlation between 10MWT and JPS 60 0 on the paretic side (r 0.824; p=0.006). However, there is no significant correlation between 10MWT and TTDPM. Conclusion:There is correlation between the propioceptive function of the knee joint and the walking speed of post-stroke patients. The smaller the percentage of joint position error, the stronger the correlation with walking speed.
