In one embodiment, a system for heel-to-shin testing includes a patient interface configured to be applied to a shin of a patient and extend from a point on the shin adjacent the knee to a point on the shin adjacent the ankle, the patient interface including an elongated medial touch sensor configured to sense contact of a heel of the patient to a centerline of the shin at any axial position between the knee and the ankle, and a control module in electrical communication with the patient interface, the control module being configured to identify a number of times the patient's heel deviates from the centerline of the shin as the patient slides the heel down the shin or drags the heel up the shin.
