Wheelchair cushion modification: device for locating high-pressure regions

Area of Science:

• Biomedical Engineering
• Rehabilitation Technology

Background:

• High seating pressures under wheelchair users can lead to decubitus ulcers.
• Accurate identification of bony prominences is crucial for effective cushion modification.

Purpose of the Study:

• To develop a portable device for identifying high-pressure regions on wheelchair seating surfaces.
• To enable direct clinical application for modifying cushions and preventing pressure ulcers.

Main Methods:

• Development of a portable, adjustable "wheelchair barograph".
• Utilizes light patterns to clinically identify high-pressure regions without requiring an electronic readout.
• Provides accurate records of high-pressure areas for patient documentation or direct cushion marking.

Main Results:

• The wheelchair barograph successfully identifies high-pressure regions on seating surfaces.
• The device provides a non-electronic method for recording pressure distribution.
• Identified high-pressure regions can be directly used for cushion modification.

Conclusions:

• The wheelchair barograph is a practical tool for clinicians.
• It aids in the modification of wheelchair cushions to reduce pressure ulcer risk.
• The device offers a simple, effective method for pressure mapping in clinical settings.
