"Walker" is an equipment for assisting self-reliance walking. In this study, the unstable motion of the gait in the human using the walker was analyzed by the tri-axial accelerometers and the motion capture system. Several markers were put on subjects' back and legs, and two high-speed video cameras were employed to record the motion of markers, respectively. The subjects were asked to walk around a test course at a voluntary speed. The activities performed on the test course include standing up, normal walking, fast walking, walking over a barrier, and falling down. We showed some results on the characteristic rules of the gait motion by using the walker. It was also indicated that the acceleration sensors are more convenient device than the motion capture system to extract the characteristics from some data. We could estimate that these methods by acceleration sensor were applicable to the gait motions of the elderly living in nursing home, and could evaluate walking motions before and after rehabilitation.
