CONTINUOUS MONITORING OF MOVEMENT IN PATIENTS WITH PARKINSON'S DISEASE USING INERTIAL SENSORS
Keywords: Parkinson's disease, movement disability, continuous monitoring, inertial sensors
AbstractGait impairment is a hallmark of Parkinson's disease (PD). The assessment of gait and balance in the clinic may not adequately reflect mobility in daily life. It is often reported that patients with PD walk better when they are examined in an outpatient clinic or in a research laboratory than at home. Continuous monitoring of mobility during spontaneous daily activities may provide clinicians and patients with objective measures of the quality of their mobility. We show that continuous monitoring of spontaneous gait with wearable inertial sensors during daily activities is feasible for patients with PD. We tested 13 patients with PD and 8 healthy controls to evaluate the feasibility of using wearable inertial sensors at home for one week. The inertial system successfully detects walking bouts and provides sixteen objective measures that can characterize gait changes in patients with PD.
