Abstract

Objective: To examine changes in seat-interface pressure in wheelchair seated spinal cord injured patients.
Method: Twenty-six spinal cord injured patients, who were motor complete tetraplegic and paraplegic patients, were included in this study. After 5 cm air-filled cushion (ROHO?) was placed on their own wheelchair seat, patients were seated on wheelchair with neutral position for sixty minutes. The interface pressure and contact area of buttock was measured every 5 minutes.
Results: Significant increases of interface pressure were found in maximal and mean interface pressure during 0 to 25 minutes of sitting (p＜0.05). An increased tendency of contact area of buttock was observed during sitting time but it was not significant.
Conclusion: There were no significant changes of interface pressure after 25 minutes of sitting in spinal cord injured patients. Therefore, twenty-five minutes may be a reasonable sitting time before interface pressure is recorded. (J Korean Acad Rehab Med 2009; 33: 614-618)
