ABSTRACT
OBJECTIVES: To measure buttock pressure during toilet seating in persons with spinal cord injury (SCI). DESIGN: A case series study. SETTING: Kibikogen Rehabilitation Center for Employment Injuries. METHODS: The study included 41 persons with SCI. Buttock pressure was measured during toilet seating, with or without a toilet seat cushion (foam cushion, gel cushion, air cushion) on the toilet seat. RESULTS: The subjects were classified into three groups according to the site of the maximum pressure [greater trochanter (GT) region, ischial tuberosities (IT), and sacral region (SR)] recorded on the pressure map of the non-cushioned toilet seat, into the GT, IT and SR groups, respectively. All three types of cushions altered the buttock pressure distribution during no-cushion toilet seating. In the GT group, all three cushions significantly reduced the peak pressure in the GT area, compared to the control (no-cushion). The foam cushion significantly increased the peak pressure in the IT area (Pisch) in the GT group, relative to the control. However, the foam cushion significantly increased while the gel cushion significantly reduced Pisch, relative to the control. In SR group, the air cushion significantly reduced the peak pressure in the SR, relative to the control. CONCLUSION: We recommend the use of the gel cushion for the IT group and the air cushion in GT and SR group to reduce buttock pressure during toilet seating in persons with SCI.
