Corsets are widely used to improve trunk stability in patients with spinal cord injury (SCI) and can improve respiratory function. The aim of the present study was to identify predictors of respiratory benefits from wearing a corset in SCI patients. In a prospective observational study, respiratory function was tested in the supine and upright seated position with and without a corset in 36 SCI patients who regularly used a corset. SCI patients who no longer used a corset were matched to users on sex, injury level and severity. Vital capacity (VC) did not differ between users and nonusers in the supine position. In users, contrary to nonusers, VC increased significantly in the supine position compared to the seated position (increase of 0.43+/-0.39 versus -0.05+/-0.32 L in nonusers; p<0.0001). Corset use was associated with a significant VC increase in the upright position (2.13+/-0.71 L without versus 2.41+/-0.69 L with the corset; p<0.001). The VC increase with the corset in the upright position correlated significantly with the VC increase induced by being supine, compared to sitting without the corset. The VC increase induced in SCI patients by lying supine may predict the effects of wearing a corset. The long-term effects of corset use should be evaluated.
束腹在脊髓损伤（SCI）患者中被广泛用于改善躯干稳定性，可改善呼吸功能。本研究旨在确定 SCI 患者佩戴束腹后呼吸获益的预测因素。在一项前瞻性观察研究中，36 名经常佩戴束腹的 SCI 患者在仰卧位和直立坐姿时分别测试佩戴和不佩戴束腹时的呼吸功能。与佩戴者相比，不再佩戴束腹的 SCI 患者在性别、损伤水平和严重程度方面相匹配。仰卧位时，佩戴者的肺活量（VC）与不佩戴者无差异。与不佩戴者相比，佩戴者的 VC 在仰卧位时与坐姿时相比显著增加（不佩戴者增加 0.43+/-0.39 升，而佩戴者增加 0.05+/-0.32 升；p<0.0001）。佩戴束腹时，直立位的 VC 显著增加（不佩戴束腹时为 2.13+/-0.71 升，佩戴束腹时为 2.41+/-0.69 升；p<0.001）。直立位佩戴束腹时的 VC 增加与不佩戴束腹时仰卧位的 VC 增加显著相关。仰卧位对 SCI 患者的 VC 诱导增加可能预测佩戴束腹的效果。应评估束腹使用的长期效果。
