When the healthy hand pulls the first handle 25 backwards, the air bag is pumped by the air cylinder 44, the pneumatic glove 4 drives the fingers of the affected hand to straighten, the angle sensor 6 collects the angle information beta of the first push rod 24 rotating around the second shaft pin 26 and transmits the angle information beta to the controller 8, the controller 8 sends a control instruction to the servo motor 72, and the servo motor 72 drives the second push rod 74 to rotate around the third shaft pin 73 by the angle beta in the same direction.

The joint reaction of the arms and fingers of the healthy side hand and the affected side hand is broken through the upper limb joint type separation reaction training, so that the free control of the arms and fingers of the affected side hand is realized.

The above embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
