In walking analysis, which is one useful method for efficient physical rehabilitation, the ground reaction force, the center of pressure, and the body orientation data are measured during walking. In the past, these data were measured by a 3D motion analysis system consisting of high-speed cameras and force plates, which must be installed in the floor. However, a conventional 3D motion analysis system can measure the ground reaction force and the center of pressure just on force plates during a few steps. In addition, the subjects' stride lengths are limited because they have to walk on the center of the force plate. These problems can be resolved by converting conventional devices into wearable devices. We used a measuring device consisting of portable force plates and motion sensors. We developed a walking analysis system that calculates the ground reaction force, the center of pressure, and the body orientations and measured a walking subject to estimate this system. We simultaneously used a conventional 3D motion analysis system to compare with our development system and showed its validity for measurements of ground reaction force and the center of pressure.
在步行分析中,这是一种用于有效身体康复的有用方法,在步行过程中会测量地面反作用力、压力中心和身体方位数据。过去,这些数据是通过由高速摄像机和测力板组成的三维运动分析系统来测量的,该系统必须安装在地面上。然而,传统的三维运动分析系统只能在几步之内测量测力板上的地面反作用力和压力中心。此外,受试者的步长受到限制,因为他们必须在测力板的中心行走。通过将传统设备转换为可穿戴设备可以解决这些问题。我们使用了一种由便携式测力板和运动传感器组成的测量设备。我们开发了一种步行分析系统,该系统可以计算地面反作用力、压力中心和身体方位,并对一名步行受试者进行测量以评估该系统。我们同时使用传统的三维运动分析系统与我们开发的系统进行比较,并证明了其在测量地面反作用力和压力中心方面的有效性。
