[0018] figure 1 In the mainframe, the multiple timing operation control modules set by the synchronization controller are nested and connected, and the two foot control trigger elements of the trigger are plugged into the trigger via the wire harness to alternately switch the operation of the walking timing and synchronously control the stimulation pulse sequence output by the stimulator. . The stimulator is equipped with a low-frequency pulse circuit module and a stimulation pulse power drive circuit module, which are plugged into four groups of electrodes A, B, C, and D by a wire harness to stimulate the movement of the affected limb. The main controller includes operation interface, memory, single-chip microcomputer and its control program.
[0019] figure 2 In, the shared trigger 02 cross-connects the left host 01 and the right host 03. When the left leg is off the ground and the left trigger element flips, the left host 01 stimulates the left leg swinging action, the right...
