Reliability and concurrent validity of spatiotemporal stride characteristics measured with an ankle-worn sensor among older individuals

Wearable inertial sensors have been shown to provide valid mean gait characteristics assessments, however, assessment of variability is less convincingly established. What level of concurrent validity, and session-to-session reliability does an ankle-worn inertial measurement unit (IMU)-based gait assessment with a novel angular velocity-based gait event detection algorithm have among older adults? Twenty seven (women N = 17) participants...
