Abstract

To handle the existing problems of a wearable inertial-sensors-based gait analysis system, the study aims to propose and implement computation schemes for correcting misaligned coordinates assigned to inertial sensors, and compensating inclined mounting on the foot and lower limbs, which results in incorrect computed gait parameters and errors in the obtained ankle flexion. A rotating device and designated joint movement were employed to justify the proposed correcting and compensating schemes.
