Effect of Different Incline Positions on Gait Kinematics During Walking on a Treadmill

The aim of this study is to investigate gait kinematics parameters such as foot angle, knee angle, and hip angle in sagittal plane during walking on a treadmill in three different incline positions at a constant speed of 5m/s. Four healthy people with the age average of 25 years worn with reflective markers are instructed to walk on a treadmill for six minutes (three minutes for inter-phase of three positions and three minutes for walking in aforementioned positions for the purpose of adapting to the walking speed). Data are obtained using 6 video cameras and Simi Motion Analysis System and then filtered by such software. Results show that there is a significant relation between changing incline position and kinematics parameters. Furthermore results indicate that the anthropometry data of subjects can affect the kinematics angles in different incline positions.
