The effects of the support panel of compression leggings on the provision of low pressure for foot progression angle correction

Abstract

This study developed compression leggings (CLs) with a support panel for foot progression angle (FPA) correction to improve the fit without restricting the user's movement while providing an appropriate external force. This study aimed to examine the effects of FPA correction concerning the functionality and usability of the support panel of CLs that ensure low pressure. Clothing pressure (CP), FPA, skin blood flow (SBF), perceived strength, and usability of OCLs during treadmill walking were compared with the normal leggings (NLs). Differences in CP, FPA, SBF, and user evaluation results were analyzed according to different wearing conditions. Despite the low CP generated by the support panel (≤3.21 mmHg), there was a significant positive orthotic effect with an 11.6–18.0% increase in FPA for external rotation and a 10.5% increase in SBF. The users felt pressure and support around the thigh where the support panel was placed and directional tensile strength throughout their lower extremities while recognizing the usefulness in gait correction. Pressure and support provided by the support panel assured appearance satisfaction, dimension satisfaction, compression satisfaction, ease of movement, and safety. This study demonstrated that the support panel of CLs provided an FPA correction effect concerning functionality and usability.
