Analysis of the Motion Activity Manual Wheelchair Users

Assistance Publique - Hôpitaux de Paris55 enrolled

Overview

Currently, there is no system in place to allow manual wheelchair users to know their quantities of movement activities and the intensity of effort to be provided during these propulsion movements. Based on recent work by Routhier et al. in 2017, and in light of the scientific literature related to wheelchair propulsion, it would seem appropriate to validate the use of inertial units as tools to quantify and categorize the intensity of manual wheelchair propulsion.

The investigator hypothesize that an inertial unit positioned on the wheelchair wheel has the same detection rate of the propulsion cycle as a dynamometric wheel (step 1). In addition, the investigator hypothesize that the categorization of the detected propulsion cycle as a function of force intensity is similar between the angular deceleration of the wheel during propulsion calculated from the inertial unit and the external mechanical power calculated from a dynamometric wheel (step 2).
