The Red Shoes 1: A Matlab method allowing one dorsal GoPro camera to track gait at 120 fps on a treadmill using the colour red: Work in Progress

In this work in progress, we describe a frugal and low-tech design for offline tracking of gait on a treadmill using a single GoPro video camera recording at 120 fps. The participant wears bright red athletic shoes and the camera is situated dorsally and above the ground line. Because this method produces most temporal variables (e.g. step times, single support times, double support times) and several spatial gait variables (e.g. stride lengths and step lengths), it can derive a range of variability measures such as stride time variability, step length variability and swing time asymmetry, which are otherwise unavailable without expensive gait equipment. This method will help to tease apart the relationship between neurodiversity (e.g. ADHD, autism, and Tourette syndrome), joint hypermobility, and their effects on gait.
