Wearing compression socks increases mean deep venous velocity, reduces venous blood retention, and improves venous return. However, no existing studies reported their effect on arteries. Thus, we aimed to determine whether wearing compression socks decreases brachial-ankle pulse wave velocity (ba-PWV).
We compared ba-PWV measurements in 106 participants (40 men and 66 women) under three conditions: bare feet, wearing normal socks, and wearing compression socks for 10 min. Mean arterial blood pressures (MAPs) were measured at the upper arms and ankles on both sides. Sensor cuffs were attached over socks to estimate pressures exerted on arterial walls by the socks in the condition of wearing socks.
Tukey's honestly significant difference test showed that PWVs for the compression sock condition were significantly lower than those for bare feet (95 % confidence intervals: 0.3051-0.9478 [right], 0.3454-0.9889 [left], p < 0.0001 on both sides) and normal sock conditions (0.0126-0.6552, 0.0656-0.7092, p < 0.04 on both sides). The mean ba-PWV of the right side decreased from 10.57 m/s (bare feet) to 9.94 m/s (compression socks) [absolute difference: 0.63 m/s; relative difference: 5.96 %]. The left-sided mean ba-PWV decreased from 10.79 m/s (bare feet) to 10.11 m/s (compression socks) [absolute difference: 0.67 m/s; relative difference: 6.21 %]. We observed no significant differences in PWVs between bare feet and normal sock conditions on either side. In the compression sock condition, the difference between upper-arm and ankle MAPs while wearing socks indicated the pressure exerted on the arterial wall by the compression socks. We found significant negative correlations between ba-PWV and the estimated pressure exerted on the arterial wall at both ankles (regression analysis, F(1, 104) = 10.55, p < 0.02) [right], F(1, 104) = 12.92, p < 0.0005 [left]).
Wearing compression socks reduced ba-PWV, indicating increased arterial compliance in lower limb arteries by applying external pressure to the arterial wall.
穿着压力袜可增加平均深静脉流速，减少静脉血潴留，并改善静脉回流。然而，目前尚无研究报道其对动脉的影响。因此，我们旨在确定穿着压力袜是否会降低臂踝脉搏波速度（ba-PWV）。
我们比较了106名参与者（40名男性和66名女性）在三种情况下的ba-PWV测量值：赤足、穿着普通袜子以及穿着压力袜10分钟。测量双侧上臂和脚踝处的平均动脉血压（MAP）。在穿着袜子的情况下，将传感器袖带套在袜子上以估计袜子对动脉壁施加的压力。
Tukey真实显著差异检验表明，压力袜情况下的PWV显著低于赤足情况（95%置信区间：右侧为0.3051 - 0.9478，左侧为0.3454 - 0.9889，双侧p < 0.0001）和普通袜子情况（右侧为0.0126 - 0.6552，左侧为0.0656 - 0.7092，双侧p < 0.04）。右侧的平均ba-PWV从10.57 m/s（赤足）降至9.94 m/s（压力袜）[绝对差异：0.63 m/s；相对差异：5.96%]。左侧的平均ba-PWV从10.79 m/s（赤足）降至10.11 m/s（压力袜）[绝对差异：0.67 m/s；相对差异：6.21%]。我们观察到两侧赤足和普通袜子情况之间的PWV无显著差异。在压力袜情况下，穿着袜子时上臂和脚踝MAP之间的差异表明压力袜对动脉壁施加的压力。我们发现ba-PWV与双侧脚踝处动脉壁上估计的压力之间存在显著负相关（回归分析，右侧F(1, 104) = 10.55，p < 0.02；左侧F(1, 104) = 12.92，p < 0.0005）。
穿着压力袜可降低ba-PWV，表明通过对动脉壁施加外部压力可增加下肢动脉的顺应性。
