Abstract: The aim of this research was to develop and validate a sensing mechanism for accurate measurement of the acceleration of human body segments and knee joint angle for gait analysis. The experimental results are correlated to establish the relation between knee angle and acceleration of lower limb. The sensing mechanism consists of indigenously developed two tri-axis accelerometers and one commercially available electro-goniometer. Experimental trials were done for walking at different speed on electric treadmill to acquire knee flexion-extension angles and acceleration of normal subjects. These correlated findings will be helpful in development of a transfemoral prosthetic device, i.e., electronic knee.

Keywords: kinematics; accelerometers; goniometers; prosthetic knees; human motion; knee joint angle; gait analysis; walking; electronic knees; transfemoral prosthetic devices.
