[0033] Specifically, the base 13 of the training chair supports the seat body 1. When the patient uses the training chair, he sits on the seat cushion assembly 2 on the seat surface 11 of the seat body 1, with his back against the backrest 12, his hands holding the armrests 14, and his feet stepping on the footrest assembly 3 at the bottom. The two seat cushion bodies 21 on the seat surface 11 correspond to the patient's two hips respectively, and the patient's two hips sit on the two seat cushion bodies 21. The seat cushion body 21 can have a variety of training methods. In one case, the patient can shake both pelvises around the seat cushion body 21 with force. The universal shafts 22 under the two seat cushion bodies 21 move with the seat cushion body 21, and the patient's pelvis tilts around for dynamic training to promote pelvic flexibility. In another case, first limit the universal shaft 22 on one side to keep the seat cushion body 21 on one side balanced. The hip on the other side of the patient can exert force around the unrestricted seat cushion body 21. The universal shaft 22 on this side is in an active state, supporting the movement of the patient's hip on this side, and performing unilateral hip training. The vibration motor 23 works to generate vibration and transmits it to the hip on this side through the fixed universal joint 22, thereby enhancing the patient's proprioception and enabling the patient to better perceive the position changes of the pelvis. The vibration of the cushion body 21 on one side is used to help the patient improve local pelvic torsion or rotation. During the whole process, the patient's feet are on two foot pedals 32, and the two foot pedals 32 are installed on the foot pedal seat 31 through the ups and downs mechanism 33. The two foot pedals 32 can also perform up and down movements, and the patient's two feet can perform stepping training accordingly, thereby enhancing the strength training and control ability of the lower limbs. The chair is equipped with both hip and foot training equipment to assist patients in pelvic tilt, unilateral hip training and lower limb training. It mainly performs biofeedback training on scoliosis of the patient's lower body. There is no discomfort during use. The device is simple to operate and the training direction involves the pelvis, hips and feet, which are difficult to design for ordinary equipment, further improving the treatment of scoliosis.

[0034] In some possible embodiments, two downwardly extending retractable brackets 15 are rotatably mounted on either side of the front of the seat 11. Two footrests 31 are mounted on the ends of the retractable brackets 15 away from the seat 11. The base 13 includes a pneumatic rod 131 connected to the center of the bottom surface of the seat 11; and a five-claw base 132 connected to the lower end of the pneumatic rod 131. Each of the five claws of the five-claw base 132 is connected to a universal wheel 133.

[0035] Specifically, the footrest assembly 3 is installed at the front lower part of the chair seat 11 at the patient's feet through two retractable brackets 15. The two retractable brackets 15 can adjust the height of the two footrest seats 31 respectively, and then adjust the height of the two foot pedals 32. Medical staff adjust the height of the foot pedals 32 on a large scale according to the conditions of different patients to adapt to the treatment conditions of different patients; the pneumatic rod 131 can support the chair seat 11 to move up and down, and adjust the height of one side according to the height of different patients. The five-claw seat 132 is more stable, and the universal wheel 133 facilitates the movement of the entire seat. The universal wheel 133 has a brake mechanism. When the seat is in use, the universal wheel 133 is braked and opened to prevent the seat from moving.

[0036] In some possible embodiments, the backrest 12 is a structure that fits the human body, and two first telescopic rods 16 are installed at intervals on the top of the backrest 12. Headrests 17 are installed on the two first telescopic rods 16, and the two armrests 14 are installed on both sides of the seat surface 11 through telescopic parts 18.

[0037] Specifically, the backrest 12 has a certain curvature, fits the human body, and is more comfortable to use. The headrest 17 can be adjusted in height by the first telescopic rod 16, and the armrest 14 can be adjusted in height by the telescopic member 18 to adapt to different patients.

[0038] In some possible embodiments, the undulating mechanism 33 includes: a plurality of second telescopic rods 331, the plurality of second telescopic rods 331 are evenly divided into two groups, the two groups of second telescopic rods 331 correspond to two foot pedals 32 and are connected to the foot pedal seat 31; a plurality of universal balls 332, the number of universal balls 332 is adapted to the number of second telescopic rods 331, the universal balls 332 are respectively installed on the top of each second telescopic rod 331, and the two foot pedals 32 are respectively connected to the universal balls 332 on the top of the two groups of second telescopic rods 331. The second telescopic rod 331 includes a sleeve 333 and a movable rod 334. A telescopic spring 335 is provided in the sleeve 333. The movable rod 334 is sleeved in the sleeve 333. The movable rod 334 moves up and down in the sleeve 333. The bottom end of the sleeve 333 is connected to the footrest seat 31, and the top end of the movable rod 334 is connected to the universal ball 332. A limiting mechanism is provided on the sleeve 333. There are ten second telescopic rods 331 and ten universal balls 332. Every five second telescopic rods 331 are respectively provided at the four corners and the middle of a footrest 32.

[0039] Specifically, five second telescopic rods 331 and five universal balls 332 under each footrest 32 connect the footrest 32 and the footrest seat 31. The five second telescopic rods 331 are respectively located at the four corners and the middle of the footrest 32. When the device is used, the patient's foot steps on the footrest 32, and the second telescopic rod 331 includes a sleeve 333 and a movable rod 334. The telescopic spring 335 under the movable rod 334 always supports the movable rod 334. The patient's foot presses down hard on one side of the footrest 32, and the footrest on that side is pressed down hard. The movable rod 334 below the plate 32 is pressed down in the sleeve 333, depressing the telescopic spring 335. At the same time, the upper part of the five universal balls 332 is fixedly connected to the foot pedal 32. The universal balls 332 can move, supporting the foot pedal 32 while being connected to the five second telescopic rods 331, and can keep a portion of the second telescopic rods 331 contracted. This structure can support the patient's feet to press down as a whole, front and back, left and right, or at an angle. The device is highly flexible and enhances the patient's ability to control the strength of the feet and lower limbs. Furthermore, the telescopic plates under the two foot pedals 32 can adjust the height of the two feet. According to the physical condition of different patients, the height of the two foot pedals 32 can be adjusted to the required level. The limiting mechanism of the second telescopic rod 331 is opened and the height is fixed. The patient's two feet are both close to the foot pedals 32 to adjust the pelvic tilt problem caused by scoliosis, thereby providing support for spinal correction. Furthermore, during use, only the individual second telescopic rods 331 under each foot pedal 32 can be limited to form an unstable foot pedal 32 plane, thereby enhancing the patient's ability to control the strength of the feet and lower limbs.

[0040] In some possible implementations, gaps are reserved between the two seat cushions 21, between the two seat cushions 21 and the backrest 12, and between the two seat cushions 21 and the two armrests 14. The outer layers of the two seat cushions 21 are wrapped with latex pads, and the two universal joints 22 are both ball-jointed universal joints 22. A pressure sensor is installed in each seat cushion 21, and each pressure sensor is electrically connected to a Bluetooth module, which is connected to a smart terminal.

[0041] Specifically, both seat cushion bodies 21 need to move at all angles in three dimensions. Space is reserved between the two seat cushion bodies 21 and between the two seat cushion bodies 21 and other surrounding parts to avoid affecting the movement of other parts or between each other or squeezing the patient's body. The ball cage universal joint 22 has the advantages of high transmission efficiency and small space occupation. The pressure sensors on the two seat cushion bodies 21 monitor the pressure distribution in the buttocks area on the seat cushion in real time. Through these feedbacks, the horizontal condition, rotation and imbalance of the load on both sides of the pelvis can be accurately judged.

[0042] In some possible implementations, the two vibration motors are connected to emergency stop buttons. The frames of the seat 11, backrest 12 and base 13 are all made of high-strength lightweight aluminum alloy.

[0043] Specifically, the high-strength and lightweight aluminum alloy material ensures the stability and lightness of the chair.
