  • W241003 A Kinematic Quantification of Gait Performance for Lumber Spinal Stenosis

抄録

A method for quantitative evaluation of gait pathology in patients with lumbar spinal stenosis (LSS) was presented. Our method utilized a miniature three-dimensional inertial sensor attaching on the upper trunk. The six LSS subjects (age 66±3 yr.) measured before surgery and after surgery at 3 months have participated in our experiment. The gait ability was examined by the six minutes walking test shuttling between thirty meters strait corridor in a hospital. Firstly, gait factors were detected by the sensor output, and then three-dimensional rotation angles of the upper body were calculated. To extract the time-variable characteristics brought by expression of pain or intermittent claudication, spectral analysis by STFT was employed. Experimental results showed that postoperative subjects were improved mainly in keeping upper body steadiness and walking smoothness. The proposed method may useful in quantifying changes of walking parameters for LSS patients.
