Evaluation of toe in stable and unstable standing

Abstract

The toe that does not contact the floor in stable standing is called floating-toe. Many people think of the floating-toe as a problem. We defined pseudo-floating-toe (PFT) as the toe that does not contact the floor in double-leg standing even though there is no motion restriction on the toe. It is necessary to confirm whether PFT is used during unstable standing. The purpose of this study is to clarify whether PFT is used during unstable standing. Seventeen women (12 women without PFT and 5 women with right-fifth-PFT) participated in this study. The subjects were asked to keep right-one-leg standing (R-OLS) on the measuring plate. The load by right-fifth-toe during R-OLS was measured by the buried sensor in the measuring plate. The duration for analysis was 5 seconds. The results showed that PFTs of all right-fifth-PFT pushed the floor during OLS. The PFTs were used in an unstable standing.
