Joint moments are very useful information in gait rehabilitation and sports training. Generally, ground reaction force and ankle joint moment of human body is measured by using 3D motion analysis device and force plate. However this conventional method is expensive, large scale and limitation of use place. In this paper, a new wearable estimation method for measuring reaction force and joint moment by using planter pressure sensors is proposed. This system is compact, easy to measure, and is flexible so as not to disturb gait. And in this study a new simple calibration method is presented using very cheap load cell in stead of the force plate. In addition, the method to estimate the joint moments in two directions is proposed. Experimental study is carried out and the practicality of the new proposed method is considered.
