[0040] Optionally, the support seat 23 is fixedly connected to the base 28 via a connecting frame 29 , and the connecting frame 29 is located on the sides of the base 28 and the support seat 23 .

[0041] Specifically, when performing waist training, the patient supports his or her hands on the table, the waist cooperates with the support frame 3, and the support seat 23 and the base 28 are connected, which can effectively increase the stability of the entire device and prevent the patient from sliding between the table and the support frame 3 when performing waist training, thereby causing safety hazards. At the same time, the connecting frame 29 is located on the side of the entire device to prevent obstruction to the patient's training process.

[0042] Optionally, a protective pad 26 is provided on the top of the table top 1 .

[0043] Specifically, it can buffer the pressure on the palm support during waist training of the patient, thereby improving comfort.

[0044] Optionally, the number of the arm support sleeves 2 is two, and a groove matching with a palm is formed at the bottom of the arm support sleeves 2.

[0045] Specifically, a groove is provided at the bottom of the arm support sleeve 2, and the patient's hand can pass through the groove to be supported on the table top. The connection between the groove and the table top is located on the side of the arm support sleeve 2, so that the patient's palm can pass through the groove when the patient is facing or facing away from the table top 1. At the same time, a cushion layer can be added to the inner wall of the arm support sleeve 2 to increase comfort. At the same time, it can also prevent excessive pressure between the inner wall of the arm support sleeve 2 and the patient's arm during waist training, thereby affecting blood circulation in the patient's arm.

[0046] In the present invention, the servo motors are all conventional servo motors on the market. The servo motors and telescopic rods are controlled by a PLC controller. By setting a corresponding control program in the controller, the servo motors and telescopic rods can be used to control the operation of corresponding mechanisms, thereby driving the patient's limbs to perform reciprocating training of different movements. By setting different control programs, multiple groups of recovery movements for inhibiting spasms can be achieved, and related audio outputs can be increased to match the movements that the patient wants to perform, thereby assisting in recovery movements.

[0047] When the present invention assists in anti-spasm training, the patient's body is covered with a waist belt 30, and the waist belt 30 can be made of Velcro straps. After being adjusted to an appropriate range, the patient is asked to stand, then support the table with both hands forward, slightly arch the body, and pass both arms through the arm support sleeve 2 to straighten the elbow joint of the affected upper limb. With the waist belt 30 fixing the body, the healthy leg is stepped back. At the same time, the audio output uses "drag sound" to play repeatedly: "shake left-center-shake right-center" to suppress body spasms.

[0048] Then help the patient to turn around, with the hips against the table while the waist belt 30 is wrapped around the body: 1, externally rotate and supinate the elbow joint of the affected upper limb and straighten it, then support the back with both hands and pass through the arm support sleeve 2, at this time, the center of gravity moves to the affected side, and at the same time, the audio output uses "drag sound" to repeatedly play "maximum belly extension - center - maximum waist bend - center", each cycle is about 15-30 seconds, slightly slower in the early stage and slightly faster in the later stage, so as to suppress the spasm of the body.

[0049] Adjust the length of the waist belt 30. When the waist belt 30 fixes the body, the patient stands and wraps the affected wrist with the armband 8. The armband 8 also uses a Velcro strap. The patient's palm is fixed to the palm plate 12 through the palm strap 14. After that, the PLC controller controls the first servo motor 11 to drive the rotating arm 7 to rotate through the shoulder shaft 27 to achieve the "upper limb raising" and "upper limb lowering" movements. The second servo motor 15 drives the palm plate 12 to rotate through the wrist shaft 13, and the palm plate 12 drives the patient's wrist to rotate to achieve the "wrist external rotation" and "wrist internal rotation" movements. The third servo motor 25 controls the rotation of the waist shaft 24, and the waist shaft 24 drives the support frame 3 to rotate. The support frame 3 is controlled by the waist shaft 24. The belt 30 drives the patient's waist to move, and different movements are achieved by the rotation amplitude. When the rotation amplitude is small, the "center of gravity moves to the left" and "center of gravity moves to the right" movements are achieved. When the rotation amplitude is large, the "trunk turns left" and "trunk turns right" movements are achieved. The controller controls the corresponding structure to perform the following movements: "raise the healthy upper limb - externally rotate the healthy wrist - lower the upper limb - raise the affected upper limb - externally rotate the affected wrist - lower the upper limb - center of gravity moves to the left - center - center of gravity moves to the right - center". At the same time, in conjunction with the frequent playback device, the "drag sound" is used to repeatedly play the voice coordinated with the above movements. One cycle is about 1-2 minutes, slightly slower in the early stage and slightly faster in the later stage, thereby lengthening the trunk of the affected side, relaxing the shoulder blade, and inhibiting spasm.

[0050] With the waist belt 30 fixing the body, the patient stands and wraps the affected wrist with the armband 8. The patient's palm is fixed to the palm plate 12 by the palm strap 14, and the patient's fingers pass through the corresponding paper tape. The controller controls the extension and retraction of the first rod and the second extension rod 22, driving the four-finger area 17 and the thumb area 16 to extend and contract, thereby realizing the "thumb abduction", "thumb adduction", "limb abduction" and "limb adduction" movements. During training, the controller controls the corresponding structure to perform the following movements, "affected wrist rotation-thumb abduction-thumb adduction-upper limb raising-upper limb adduction-left trunk rotation-right trunk rotation-both arms raised horizontally-return-both arms raised to the top of the head-left trunk rotation-return-right trunk rotation-return", and at the same time, in conjunction with the frequent playback device, the "drag sound" is used to repeatedly play the voice matching the above movements. One cycle is about 2-3 minutes, slightly slower in the early stage and slightly faster in the later stage, thereby stretching the patient's arms and fingers, relaxing the palm and arm muscles, and inhibiting spasms. When raising both upper arms, pay attention to start by raising the affected upper limb to about 30 degrees relative to the trunk, then increase by about 5-10 degrees each time, and 10-15 times as a cycle.

[0051] 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.
