Leg volume reduction during tiptoe movement is caused by venous ejection and calf muscle contraction.
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.
期刊介绍：
The leading scientific journal devoted entirely to venous disease, Phlebology is the official journal of several international societies devoted to the subject. It publishes the results of high quality studies and reviews on any factor that may influence the outcome of patients with venous disease. This journal provides authoritative information about all aspects of diseases of the veins including up to the minute reviews, original articles, and short reports on the latest treatment procedures and patient outcomes to help medical practitioners, allied health professionals and scientists stay up-to-date on developments.
