Design and development of a wheelchair seating pressure relief reminder system for pressure ulcer prevention among paraplegics

Individuals with paraplegia spend their time on the wheelchair for life. Adapting to prolonged wheelchair seating for almost all activities of daily living is challenging. The loss of abilities to sense any pain or excessive seating pressure cause them to remain seated on the wheelchair without any...

Hamzaid, Nur Azah Chung, Tze Yang R Medicine RA Public aspects of medicine RA0421 Public health. Hygiene. Preventive Medicine Individuals with paraplegia spend their time on the wheelchair for life. Adapting to prolonged wheelchair seating for almost all activities of daily living is challenging. The loss of abilities to sense any pain or excessive seating pressure cause them to remain seated on the wheelchair without any pressure relief activities. This situation leads to secondary complications including pressure ulcer which further degrades the individual’s health. To overcome this, a wheelchair seating pressure relief training system (WSETs) was developed. Optimal placement of the force sensitive resistors (FSR) as seating pressure sensors on the cushion were determined, and their responses were investigated with 5 paraplegics. Two different FSR orientations, A and B, were compared. Each paraplegic sat in resting position and then performed pressure relief activities (PRA) which included whole body push-up, left and right lean and forward lean, before returning to resting position. Orientation B, with more forward positioned FSRs, showed higher sensitivity, implying better capture of high-risk area of pressure ulcer development. The FSR sensor readings were significantly different among pressure relief activities in all subjects (p < 0.05) indicating the validity of FSR measures for the intended application. In conclusion, the WSETs system was proven suitable as a training tool for new paraplegics to habituate themselves in performing PRA. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
