GAIT MONITORING SYSTEM, METHOD AND DEVICE

摘要

A method for monitoring gait of a subject includes operating an image capture device such as a digital camera, to capture at least one image of a region of interest of the subject during ambulation on a walking surface. Captured images are processed to identify automatically pixels representing a relevant feature of the subject and a virtual marker such as a 3D coordinate marker is assigned to the identified pixels. The virtual marker is processed to calculate a gait parameter for the subject, typically bycomparing a virtual marker assigned to a captured image with a virtual marker assigned to a subsequently captured image, determining movement of the relevant feature of the subject between the two captured images, and calculating the gait parameter according to the determined movement. The method is computer-implemented, with the image capture device mounted on an ambulatory aid such as a wheeled walking frame. A system and devices for monitoring gait are also disclosed.
