Pressure distribution analysis in three wheelchairs cushions of subjects with spinal cord injury

Abstract

Purpose: Pressure injuries are a complication due to spinal cord injury. The objective of the study is to compare the pressure distribution in the wheelchair seat of subjects with spinal cord injury using 3 pads (Roho^®, Varilite^® and Jay^®).

Methods: Pressure analysis was performed on 10 participants in two situations: (a) the participant sitting in static posture and (b) with the wheelchair being used for locomotion.

Results: In the static position: Jay^® showed the best rates for average pressure and also the contact area, the Roho^® had the lowest average for the peak pressure. During the wheelchair moving, Jay^® showed the best average pressure, Roho^® had a lower average for peak pressure and Varilite^® provided a highest means for the contact area of the buttocks and thighs.

Conclusions: The use of appropriate cushion is an effective measure in people with spinal cord injury.

Implications for Rehabilitation

• Pressure injuries are a complication due to spinal cord injury.

• Study to compare the pressure distribution in the wheelchair seat of subjects with spinal cord injury is important to minimize the injuries resulting from pressure injuries.

• The comfort resulting from the use of the cushion suited to the demands of the subjects with spinal cord injury is fundamental for the process of rehabilitation and social participation of the people affected.

• Understanding and minimizing pressure points can contribute to the appropriate rehabilitation process.
