The present invention relates to postural rehabilitation methods, the first step of each measuring foot load right and left foot, and the second process of the real-time display ever possible cross-over to the left to the graph values ​​foot load right in accordance with the measurements and , and postural rehabilitation method and then analyzed on the basis of the value of each load foot right and left to the displayed including values ​​each average value and an integral feature a carrying out the third process of the final display, the amount of process of a real-time display in case the load of the foot is made, including the second-second process of the real-time display to the continuum state in which the difference between the second-first process, and a load amount of the foot shown in the bar graph about the reference line, the third process is left step of displaying the right foot load to the car and around the base line and the reference line the right foot and left foot load difference Based on the frequency that varies mainly carried out by a frequency analysis waveform of a Fourier transform. Accordingly, the present invention makes it possible to use it by looking to the intensive recognizes the frequencies of the corresponding changes so that you can see in real time the variation in the load of the right foot and the left foot to the bar and wave conditions convenient for rehabilitation.
