[0059] Specifically, as the backboard 3 moves forward, the head push plate 27 pushes the patient's head forward from the back of the head, and the patient's torso leans forward driven by the forward movement of the head; the specific structure of the bracket 26 is not specifically limited, and a rod-shaped bracket 26 can be used, which can connect the backboard 3 and the head push plate 27, and the head push plate 27 can adopt an arc-shaped plate push plate.

[0060] In summary, when the sitting shoulder activity device for hemiplegic patients provided by the present invention is used, take the patient with left hemiplegia as an example: the patient sits on the seat plate 1 with the help of his family, and the back plate 3 is behind the patient. The left armpit push plate 7 and the right armpit push plate 8 pass through the patient's left armpit and right armpit respectively and bend upward to the upper side of the patient's shoulder through their hook-shaped rod portions 21, so that the left armpit push plate 7 and the right armpit push plate 8 can not only play a supporting role from the patient's armpit, but also drive the patient's shoulders to move up and down with them; then the patient's left and right hands are respectively placed in the hand accommodating grooves 13 of the two hand fixing structures, and the cover plate 14 is covered to realize the patient's positioning of the left and right hands. At the same time, the arc plates of the two elbow limit plates 6 form a semi-wrapped state for the patient's elbows, and press against the outside of the patient's elbows, so that the patient's left arm and right arm remain in a straight state. During the training process, the first drive motor 11 is first started to drive the rotating rod 4 to rotate, driving the patient's left arm and right arm to move to the oblique rear of the patient's body. At the same time, the second drive motor 16 rotates to drive the circular plate 12 to rotate relative to the moving plate 5, so that during the movement of the patient's arm, the direction of the patient's four fingers also changes accordingly, forming a state in which the patient's hand is in a state in which the four fingers point to the oblique rear of the patient's body. Then in this state, the two first linear modules 17 are started, and the two first linear modules 17 drive their respective sliders to move left. Under the pushing effect of the right underarm push plate 8 on the patient's body to the left, the patient's center of gravity shifts to the left; at this time, the two second linear modules 18 are started again, and the second linear module 18 on the left drives the left underarm push plate 7 to move upward, and the second linear module 18 on the right drives the right underarm push plate 8 to move downward, forming a state in which the patient's left shoulder blade is too high and the right shoulder blade is lowered, and this state is maintained for the first set time. After that, the patient's center of gravity is transferred to the right side of the patient in the same way, and the patient's right shoulder blade is too high and the left shoulder blade is lowered, and this state is maintained for the first set time. Repeatedly moving the patient's shoulders in the sitting position can inhibit the spasm of the upper limbs through the movement of the proximal limbs.

[0061] After the above training is completed, the two hand fixing structures can be driven to move to the left and right sides of the patient's body respectively by rotating the rotating rod 4, and at the same time, the second driving motor 16 rotates, driving the circular plate 12 to rotate relative to the moving plate 5, so that during the movement of the patient's arm, the direction of the patient's four fingers also changes accordingly, forming a state in which the patient's hand points to the left and right sides of the patient's body. Then, when the patient's center of gravity is on the left and on the right, the two second telescopic components 19 are started, and the patient's left shoulder and right shoulder are alternately moved forward and backward by the two second telescopic components 19 being retracted back and forth alternately, further training the patient's left and right shoulders, promoting the multi-directional movement of the patient's left and right shoulder blades, and inhibiting the upper limb spasm caused by shoulder blade abnormalities.

[0062] After the above training is completed, the two hand fixing structures can be driven to move to the left rear and right rear of the patient's body respectively by the rotation of the rotating rod 4. In this state, the left arm and the right arm of the patient are stretched to the rear of the body as much as possible. At the same time, the second driving motor 16 rotates, driving the circular plate 12 to rotate relative to the moving plate 5, so that during the movement of the patient's arm, the direction of the patient's four fingers also changes accordingly, forming a state in which the patient's hand is in a state where the four fingers point to the rear of the patient's body, stretching the muscles of the patient's arm and shoulder. Then keep the patient's center of gravity in the middle, start the first telescopic component 9, drive the back plate 3 to move forward, and push the patient's head forward through the head push plate 27. Driven by the movement of the head, the patient's trunk and head are tilted forward as a whole, and the shoulder blades are stretched forward. After maintaining the second set time, the first telescopic component 9 drives the back plate 3 to move backward, and driven by the hook-shaped rods 21 of the left underarm push plate 7 and the right underarm push plate 8, the patient's trunk and head move backward, driving the shoulders on both sides to retract backward, and also maintaining the second set time. This is repeated while the patient is sitting, and the movement of the trunk and head can suppress the spasm around the patient's shoulder blades and also suppress the spasm of the patient's arms.

[0063] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
