Development of a video-based technique for ambulatory monitoring of foot placement with an instrumented rollator

Abstract

The video-based system mounted on a rollator to collect foot placement data enabled accurate measurement of step width during rollator use. The ability to record foot placement measurements outside the laboratory setting, characterizing foot placement patterns occurring in the community, will enable research into how these assistive devices influence mobility during everyday use.

Assisted Gait Phase Estimation Through an Embedded Depth Camera Using Modified Random Forest Algorithm Classification

“…In the second approach, different kind of supports are used to move the camera. In [38] and [39] for example, a RGB camera is mounted on instrumented rollators moved by healthy subjects. The camera captures the feet of the subject during the locomotion, and estimates the step width from the video data.…”

A wearable smartphone-enabled camera-based system for gait assessment

“…Portable video recording enables a more accurate assessment technique. For example, iWalker is a system that utilizes a pair of cameras mounted on the rollator frame to capture step width [17]. This system, however, is limited to the people who use rollators and cannot be adopted for wider population.…”
