Objective: This is a retrospective study to determine how much the pressure distribution adjustment of a wheelchaircushion using a pressure image sensor actually affects the prevention of pressure injury, which is a majorcomplication in patients with a spinal cord injury.
Methods: This study was conducted on 132 patients with a spinal cord injury with an onset of less than 1 year. Thestudy group proceeded using their own wheelchair cushion when adjusting the pressure distribution of the cushion,and were classified into 66 patients who could continue to use the wheelchair cushion, the pressure of which wasadjusted according to the individual. The control group was divided into 66 patients who were unable to continueto use an adjusted wheelchair cushion for various reasons. All subjects investigated the occurrence and timing ofa pressure injury once every 1 and 2 years after adjusting the pressure distribution of the wheelchair cushion.
According to these results, the incidence and timing of a pressure injury in the two groups were compared andanalyzed to determine the effect of the adjustment of the pressure distribution of the wheelchair cushion on theprevention of pressure injury in patients with a spinal cord injury. All statistical significance levels in the datawere set to p < .05.
Results: Although the difference in the probability of occurrence of a pressure injury between the experiment andthe control groups was insignificant (p < .05), the comparison results between the two groups on the timing of thepressure injury showed a significant difference (p < .05).
Conclusion: It was difficult to continuously maintain the effect of preventing pressure injury by only adjusting thepressure distribution of the wheelchair cushion once. However, if maintenance can be continued in a timelymanner, the present approach can be suggested as an extremely good method for the future prevention andmanagement of pressure injuries in patients after a spinal cord injury.
