We analyze the effects of graduated compression stoking (GCS) on walking capacity and oxygen saturation in intermittent claudication (IC) patients.
Eighteen patients with IC performed the 6-minute walking test in 2 conditions in random order: GCS or placebo sock. Onset claudication distance and total walking distance were obtained. The calf muscle oxygen saturation was continuously monitored before, during, and after 6-minute walk test. Comparisons of the walking capacity and StO parameters between GCS and placebo conditions were analyzed by Wilcoxon rank-sum test.
The onset claudication distance (GCS: 120 ± 99 meters vs. placebo: 150 ± 126 meters; P = 0.798) and total walking distance (GCS: 330 ± 108 meters vs. placebo: 324 ± 60 meters; P = 0.130) were similar between conditions. There were no differences in StO parameters between conditions (P > 0.05).
GCS does not decrease walking performance and calf muscle oxygenation saturation during 6-minute walk test in patients with IC.
我们分析了渐进性加压袜（GCS）对间歇性跛行（IC）患者步行能力和血氧饱和度的影响。
18例IC患者随机顺序在两种情况下进行6分钟步行试验：GCS或安慰剂袜。记录起始跛行距离和总步行距离。在6分钟步行试验前、试验期间和试验后持续监测小腿肌肉血氧饱和度。采用Wilcoxon秩和检验分析GCS与安慰剂条件下步行能力和血氧饱和度参数的比较。
两种条件下的起始跛行距离（GCS：120±99米 vs. 安慰剂：150±126米；P = 0.798）和总步行距离（GCS：330±108米 vs. 安慰剂：324±60米；P = 0.130）相似。两种条件下的血氧饱和度参数无差异（P>0.05）。
在IC患者的6分钟步行试验中，GCS不会降低步行表现和小腿肌肉氧合饱和度。
