Evaluation of gait parameters by the knee accelerations

摘要: A portable micro-processor based data acquisition system has been developed to measure the acceleration of both legs during gait for ambulatory subjects and evaluate temporal spatial parameters. Experiments were performed on ten hemiplegic patients with different Brunnstrom stage (Br stage) grading. The orthogonal at knee joint was measured from walking a normal speed. results according various parameters such as cycle stance significantly among Br stage. This monitor may promise allow quantitative evaluation in hospital environment their home.
