Mobile Clinical Gait Analysis Using Orient Specks

This paper explores the use of Orient specks as on-body network of wireless inertial-magnetic sensors to capture the parameters of the human gait for mobile clinical gait analysis. A range of kinematic and temporal parameters were measured for normal humans using Orient specks and compared to values obtained from a commercial Vicon optical motion capture system. There was a good correlation between the joint angle data from the two systems, most notably in the sagittal plane. Hip flexion graphs showed the highest correlation value of 0.973, with knee flexion at 0.855 and pelvic rotation at 0.943, followed by pelvic obliquity at 0.689 and ankle flexion at 0.626. We conclude that the Orient specks have the potential for obtaining gait parameters outside the laboratory environment by measuring temporal parameters, and detecting the shape and trend of kinematic parameters of the patients when they are out and about during their everyday lives.
