Abstract

Objectives: To clarify the cause of leg volume reduction during tiptoe movement in the standing position.

Methods: The right legs of 20 participants were assessed. The participants performed tiptoe movement in the supine position, and then stood up and performed the tiptoe movement and ankle dorsiflexion. Leg volume changes were recorded continuously using air plethysmography.

Results: Differences between leg volume changes due to tiptoe movement and the refilling volumes were not significantly different between the supine (59 mL) and standing (49 mL) positions, indicating that this amount of motion artifact was included in the downward trace recorded by tiptoe movement in the standing position.

Conclusions: Leg volume reduction during tiptoe movement in the standing position included a significant amount of motion artifacts. Therefore, it may be difficult to accurately measure the ejection volume using tiptoe movement in the standing position.

脚尖运动时腿部体积减小是由静脉射血和小腿肌肉收缩引起的。

目的:探讨站立时脚尖运动时腿部体积减小的原因。方法:对20例受试者的右腿进行评估。参与者在仰卧位时进行脚尖运动，然后站起来进行脚尖运动和踝关节背屈。使用空气体积描记仪连续记录腿部体积变化。结果:在仰卧位(59 mL)和站立位(49 mL)之间，由于脚尖运动引起的腿部体积变化和填充体积的差异无显著性差异，表明该运动伪影量包含在站立位脚尖运动记录的向下轨迹中。结论:站立位置脚尖运动时腿部体积减少包括大量的运动伪影。因此，在站立位置使用脚尖运动可能难以准确测量弹射量。
