Carotid-femoral pulse wave velocity (cfPWV) is widely used to measure arterial stiffness. The type of legwear worn by participants during the measurement may introduce variabilities because different fabric materials and thicknesses may disturb arterial waveforms. Therefore, we investigated the impact of common legwear on cfPWV measured using tonometry and oscillometry. We studied 50 adults (36 women) varying widely in age (19-78 years). We evaluated cfPWV using two commonly used devices that detect femoral pulses using tonometric and cuff-based oscillometric sensors. The participants wore thin medical shorts as the reference condition, khaki pants, sweatpants, and athletic shorts, with an optional bare skin condition (optimum control) with 10 min of rest between measurements. Both devices produced similar cfPWV among different legwear with no significant systematic differences. The range of cfPWV was 647-649 cm/s for the tonometric device and 482-500 cm/s for the oscillometric device across different types of legwear. Mean values of cfPWV measured with a bare skin condition did not differ significantly from other legwear. No data output rates were 13% for khaki, 6% for sweatpants, 3% for medical shorts, athletic shorts, and bare skin using the tonometry while the oscillometric device had a 0% no data output rate among all conditions. We concluded that relatively thin legwear did not appear to affect arterial stiffness as assessed by cfPWV. However, stiffer legwear, such as khaki pants, presents a challenge to detect femoral pulses when using a tonometric sensor.
颈股脉搏波速度（cfPWV）被广泛用于测量动脉僵硬度。测量过程中参与者所穿的腿部衣物类型可能会引入变异性，因为不同的织物材料和厚度可能会干扰动脉波形。因此，我们研究了常见腿部衣物对使用眼压测量法和示波测量法测得的cfPWV的影响。我们研究了50名年龄跨度较大（19 - 78岁）的成年人（36名女性）。我们使用两种常用设备评估cfPWV，这两种设备分别使用眼压传感器和基于袖带的示波传感器来检测股动脉脉搏。参与者穿着薄款医用短裤作为参考条件，此外还穿着卡其裤、运动裤和运动短裤，同时设置了一个可选的裸肤条件（最佳对照），每次测量之间休息10分钟。两种设备在不同的腿部衣物条件下测得的cfPWV相似，没有显著的系统差异。对于眼压测量设备，不同类型腿部衣物条件下cfPWV的范围是647 - 649厘米/秒，对于示波测量设备则是482 - 500厘米/秒。裸肤条件下测得的cfPWV平均值与其他腿部衣物条件下的平均值没有显著差异。使用眼压测量法时，卡其裤的无数据输出率为13%，运动裤为6%，医用短裤、运动短裤和裸肤条件下均为3%；而示波测量设备在所有条件下的无数据输出率均为0%。我们得出结论，相对较薄的腿部衣物似乎不会影响通过cfPWV评估的动脉僵硬度。然而, 较硬的腿部衣物，如卡其裤，在使用眼压传感器检测股动脉脉搏时会带来挑战。
