Supporting system for prevention of pressure sores

Pressures sores are serious problem for patients with spinal cord injuries (SCI). Many kinds of pressure-relieving cushions have been developed to distribute the weight evenly and widely. In rehabilitation medicine, the selection and the adjustment of the wheelchair cushion must be done very carefully by the medical staff to try to prevent pressure sores. In this paper, we calculate six parameters and represent these parameters on a hexagonal radar plot to evaluate the buttock pressure distribution. Using the radar plot, it is easy to select the best cushion and to adjust the air quality of the air cushion. Moreover, it is useful for the SCI patients to study their posture on the wheelchair and the prevention of pressure sores
