A Gait Extraction System (GES) was developed to investigate the accuracy of wearable sensors by producing gait parameters, to be compared against a gold standard motion capture system. Two inertial measurement units (IMUs) were placed in the lower limb region, specifically in the shank region of each leg. The GES uses algorithms to extract the gait cycle from raw acceleration data to produce gait parameters such as stride length, stride time, step length, step time, stance time, swing time and cadence. There were three main trials that consisted solely of a flat road, a road with small hills and a …
