Physical activity and transcutaneous oxygen pressure in men with spinal cord injury.

Abstract

This pilot study proposed a method for assessing the status of vascular flow measured by transcutaneous oxygen pressure (TcPO2) in the area of the ischium in people with spinal cord injury (SCI). In a sample of 38 men (two groups: 12 physically active and 26 sedentary) with thoracic SCI, the distribution of the physiological response of the tissues under load during sitting was assessed through analysis of ischium TcPO2 values obtained by an oximeter. TcPO2 baseline, recovery time of TcPO2 after sitting (Trec), the percentage of TcPO2 (%TcPO2) of maximum pressure TcPO2, and mechanic maximal pressure (Pmax) were evaluated. Trec in the physically active group was significantly lower (p < 0.05) than in the sedentary group. Likewise, significant differences in %TcPO2 between groups (p < 0.05) were also found. We concluded that the physiological response of the tissues under an individual with SCI's own weight resulting from prolonged sitting is better in those who are physically active.
