Measurement of Multiphysical Fields at the Subject-sitting Interface

Not yet recruiting

• Conditions: Wheelchair Users
• Interventions: Device: instrumented wheelchair

• Registration Number: NCT05650671
• Lead Sponsor: Université de Reims Champagne-Ardenne

Brief Summary

With the population ageing and the increase in disabilities prevalence, demand for wheelchairs is increasing. Padding and shape of seat are important factors for comfort when sitting for long periods of time. Sustained mechanical loads induced by the seated stance can cause pressure ulcers in the ischial prominences. Temperature and humidity have also been shown to be important in the development of pressure ulcers.

Detailed Description

The aim of this research is to measure the pressure, temperature and relative humidity fields at the user-seat interface of a wheelchair.

"wheelchair user-seat" group	instrumented wheelchair	healthy subjects agreeing to participate in the study

Primary Outcome Measures

Name	Time	Method
pressure	Day 0	Pressures at the user-seat interface of a wheelchair will be measured by non-invasive method using a pressure pad positioned directly on the cushion, under the seated subject. No contact with the skin will take place
temperature	Day 0	Temperatures at the ischial tuberosities will be measured by a non-intrusive methods using sensors taped directly on the pants of the participants. No contact with the skin of the participants will take place
humidity	Day 0	Humidity at the ischial tuberosities will be measured by a non-intrusive methods using sensors taped directly on the pants of the participants. No contact with the skin of the participants will take place
