The development and testing of a system for wheelchair stability measurement.

Wheelchair stability has an impact on safety as well as wheelchair performance, propulsion and manoeuvrability. Wheelchair stability is affected by the addition of life-supporting heavy equipment, e.g.

Establishing user needs for a stability assessment tool to guide wheelchair prescription.

Purpose: The WheelSense project aims to develop a system for assessing the stability and performance of wheelchairs through a user-centred design process. This study sought to capture user needs and define the specification for the system.

Method: A mixed methods approach was adopted.

The effect of seat shape on the risk of pressure ulcers using discomfort and interface pressure measurements.

Background: It is clinically known that shape is important when selecting or designing a wheelchair support surface for the prevention of pressure ulcers (a £ 2 billion annual cost to the National Health Service, UK); however, the effect of different levels of shape contouring has not been adequately studied.

Objectives: To investigate the effect of seat shape on the risk of pressure ulcers using discomfort and interface pressure measurements.

Study Design: Randomised, repeated trial.

Evaluation of the Force Sensing Application pressure mapping system.

Pressure mapping techniques are used in wheelchair and seating services to assess posture and assist in the prevention and treatment of pressure ulcers. The Force Sensitive Application (FSA) pressure mapping systems in Wales have a high clinical use and frequent calibration is required. This project aimed to assess the performance of the systems and develop a calibration strategy.
