Quantification of Gait Stability During Incline and Decline Walking: The Responses of Required Coefficient of Friction and Dynamic Postural Index.

This study aims to investigate the gait stability response during incline and decline walking for various surface inclination angles in terms of the required coefficient of friction (RCOF), postural stability index (PSI), and center of pressure (COP)-center of mass (COM) distance. A customized platform with different surface inclinations (0°, 5°, 7.5°, and 10°) was designed.

Lower extremity joint reaction forces and plantar fascia strain responses due to incline and decline walking.

Purpose: The present study aims to investigate the effect of incline and decline walking on ground and joint reaction forces (JRF) of lower extremity and plantar fascia strain (PFS) under certain surface inclination angles.

Methods: Twenty-three male subjects walked on a customized platform with four different surface inclinations (i.e.

Effects of Running Surface Stiffness on Three-Segment Foot Kinematics Responses with Different Shod Conditions.

Objective: The aim of this study was to investigate the effects of surface stiffness on multisegment foot kinematics and temporal parameters during running.

Methods: Eighteen male subjects ran on three different surfaces (i.e.
