Clothing pressure analysis of commercial women's leggings for applying medical compression classes

Abstract

The high-elasticity bottoms applying gradual pressurization to the blood vessels of the lower extremities simultaneously assisting to both prevention and treatment of multiple health conditions such as varicose veins. Medical compression stockings are classified as medical supplies, and there is a clear standard on magnitude and application for gradual pressure. However, in the case of leggings, there are no relevant experimental data or papers supporting these findings. This study was performed in order to analyse the gradual compression values in legging. Eight types of leggings currently available on the market by different brands, were analysed to determine the type of pressure applied. The pressure was measured at five points of the clothed body with leggings pulled across lower extremities. An airpack sensor was attached to a wooden leg model and five consecutive records at each measuring point were taken. Afterwards the average values were calculated. As observed in all eight leggings, the measuring point with the highest pressure applied was the back of the calf (mean 18.25 mmHg) or the below the knee circumference (mean 13.83 mmHg), pointing to deviance in applying gradual pressure as proposed in medical compression stockings. The commercial leggings used in this experiment did not show a gradual increase in pressure from the thigh to the ankle body zone. One can presume that the legs’ fatigue would increase over the time. Since, the gradual pressure should be applied in legging construction as seen in medical compression stockings.
