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.
这项初步研究提出了一种评估脊髓损伤（SCI）患者坐骨区域经皮氧分压（TcPO2）测量的血管血流状况的方法。在38名患有胸段SCI的男性样本（两组：12名身体活跃者和26名久坐者）中，通过分析血氧计获得的坐骨TcPO2值，评估了坐姿下负荷时组织的生理反应分布。评估了TcPO2基线、坐姿后TcPO2的恢复时间（Trec）、最大压力TcPO2的TcPO2百分比（%TcPO2）和机械最大压力（Pmax）。身体活跃组的Trec显著低于久坐组（p < 0.05）。同样，两组之间的%TcPO2也存在显著差异（p < 0.05）。我们得出结论，久坐导致的SCI患者自身重量下组织的生理反应在身体活跃者中更好。
