Description

Technical Field

[0001] The present invention relates to a method for using a medical rehabilitation training device, in particular to a method for using an intelligent center of gravity transfer trainer. Background Art

[0002] Currently, after many stroke patients or patients with other diseases are cured, they still have serious sequelae, including that the center of gravity is not on the central axis of the human body, the supporting force of the lateral limbs is insufficient, the center of gravity transfer is not sufficient, the center of gravity line shifts to one side, affecting the recovery of the patient's walking ability, etc.; the publicly disclosed utility model patent "Center of Gravity Transfer Trainer" with application number 202421865842.9 and the invention patent "Method for Using a Center of Gravity Transfer Trainer" with application number 202411059542.6, the center of gravity transfer trainer includes a balance training board, a housing, a left spring, a right spring and a balance indicating needle. The balance training board is hinged to the housing. The left spring and the right spring are arranged in the housing. The left spring and the right spring are located below the balance training board. The left spring and the right spring are respectively on both sides of the hinge axis where the balance training board is hinged to the housing. The hinge axis is located in the middle of the balance training board. The balance indicating needle is connected to the balance training board; when a rehabilitation patient is undergoing rehabilitation training, the intelligent center of gravity transfer trainer is placed on a flat ground, and the rehabilitation patient's feet stand on the balance training board. The balance training board is swung by using both feet. The balance indicating needle is used to display the process of the patient's center of gravity movement. The balance indicating needle indicates the situation of the patient's center of gravity movement and the force balance of both feet. The balance indicating needle is used to guide the two feet of the rehabilitator to exert force. The two feet are used to overcome the elastic force of the left spring or the right spring, and the balance training board is adjusted to be parallel to the ground or the horizontal line, training the two feet of the rehabilitator to exert force evenly, so that the two feet of the rehabilitator gradually return to the state of exerting force evenly; its defect is that: the elastic forces of the left spring and the right spring and the swing amplitude of the balance indicating needle, the left swing and right swing data of the center of gravity transfer indicated by the balance indicating needle cannot provide accurate center of gravity transfer gravity data for doctors for rehabilitation patients, including how many grams the center of gravity transfers to the left and how many grams it transfers to the right, or the accurate ratio of the left and right transfers of the center of gravity, affecting the doctor's assessment of the patient's rehabilitation and the doctor's further medical plan; the "Center of Gravity Transfer Trainer" with application number 202421865842.9 and the invention patent "Method for Using a Center of Gravity Transfer Trainer" with application number 202411059542.6 are only suitable for the center of gravity transfer training of rehabilitation patients; a method for using an intelligent center of gravity transfer trainer has become a need for the center of gravity transfer training of rehabilitation patients and for doctors to provide accurate center of gravity transfer data of patients and formulate the next medical plan. Summary of the Invention

[0003] The objective of the present invention is to overcome the deficiencies of the prior art and provide a brand-new method for using an intelligent center-of-gravity transfer trainer, which is used for the center-of-gravity transfer rehabilitation training of stroke patients or other disease patients, and to meet the needs of providing accurate center-of-gravity transfer data of patients for doctors and formulating the next medical plan.

[0004] The technical solution adopted by the present invention is as follows: The intelligent center-of-gravity transfer trainer includes a housing, a center-of-gravity moving device, and a controller. The center-of-gravity moving device and the controller are installed on the housing. The center-of-gravity moving device includes an arc-shaped swing plate and a swing amplitude indicating needle. The swing amplitude indicating needle is fixed on the arc-shaped swing plate, and the arc-shaped swing plate is movably connected to the housing. The controller includes a left gravity sensor, a right gravity sensor, a display, a left distance sensor, and a right distance sensor. The left gravity sensor and the right gravity sensor are arranged on the bottom plate of the housing. The left gravity sensor is located on the left side of the arc-shaped swing plate, and the right gravity sensor is arranged on the right side of the arc-shaped swing plate. The left distance sensor is arranged at the left end of the arc-shaped swing plate, and the right distance sensor is arranged at the right end of the arc-shaped swing plate. The controller is connected to the left gravity sensor, the right gravity sensor, the display, the left distance sensor, and the right distance sensor through control lines.

[0005] When using the intelligent center of gravity transfer trainer, place the intelligent center of gravity transfer trainer on a flat ground. According to the patient's condition, the doctor asks the rehabilitation patient to stand on the center of gravity moving device, with the patient's left foot on the left side of the arc swing plate and the right foot on the right side of the arc swing plate, so that the center of gravity of the human body is between the left and right feet; during training, guide the patient to exert force with the left or right foot. When the patient exerts force with the left foot, the center of gravity of the patient's human body shifts to the left, and the swing indicating needle on the arc swing plate swings to the left following the arc swing plate. Through the swing indicating needle, the patient can clearly see the swing amplitude of the left shift of the human body center of gravity. At the same time, when the arc swing plate swings to the left, the arc swing plate presses on the left gravity sensor on the outer shell bottom plate. The left gravity sensor transmits the data to the controller, and the controller transmits the data to the display, and accurately displays the gravity of the patient's center of gravity left shift through the display; when the patient exerts force with the right foot, the center of gravity of the patient's human body shifts to the right, and the swing indicating needle on the arc swing plate swings to the right following the arc swing plate. Through the swing indicating needle, the patient can clearly see the swing amplitude of the right shift of the human body center of gravity. At the same time, when the arc swing plate swings to the right, the arc swing plate presses on the right gravity sensor on the outer shell bottom plate. The right gravity sensor transmits the data to the controller, and the controller transmits the data to the display, and accurately displays the gravity of the patient's center of gravity right shift through the display; while the arc swing plate swings to the left, the left distance measuring sensor at the left end of the arc swing plate transmits the distance data between it and the bottom plate of the outer shell to the controller, and the controller controls the left transfer ratio display box to display the ratio of the patient's center of gravity left transfer; while the arc swing plate swings to the right, the right distance measuring sensor at the right end of the arc swing plate transmits the distance data between it and the bottom plate of the outer shell to the controller, and the controller controls the right transfer ratio display box to display the ratio of the patient's center of gravity right transfer.

[0006] The beneficial effects of the present invention are as follows: The intelligent center-of-gravity transfer trainer includes a center-of-gravity moving device and a controller. The center-of-gravity moving device includes an arc-shaped swing plate and a swing amplitude indicating needle. The controller includes a left gravity sensor, a right gravity sensor, a display, a left distance sensor, and a right distance sensor. When the intelligent center-of-gravity transfer trainer is in use, after the left foot and the right foot of the rehabilitation patient step on the left footprint and the right footprint symmetrically on the flat pedal of the arc-shaped swing plate respectively, under the guidance of a doctor, the patient controls the swing of the arc-shaped swing plate with the left foot and the right foot, and uses the swing amplitude indicating needle to follow the swing of the arc-shaped swing plate to indicate the left or right shift of the center of gravity. At the same time, through the left gravity sensor, the right gravity sensor, the left distance sensor, and the right distance sensor of the controller, the gravity of the center-of-gravity transfer and the ratio of the center-of-gravity transfer are detected, and the gravity of the center-of-gravity transfer and the ratio of the center-of-gravity transfer are displayed through the display. While the patient is undergoing rehabilitation training, accurate data on the gravity of the patient's center-of-gravity transfer and the transfer ratio are provided for the doctor, not only allowing the patient to see the situation of their own center-of-gravity transfer, but also providing a basis for the doctor to formulate the next medical plan. In addition, after the patient is discharged from the hospital, under the guidance of the doctor and the instruction manual, with the assistance of family members, the intelligent center-of-gravity transfer trainer is used for further home rehabilitation training, and the data of the center-of-gravity transfer are provided to the doctor, enabling the doctor to provide a further rehabilitation treatment plan for the patient.

[0010] In order to enable the rehabilitation trainer to clearly visually estimate the amplitude of the center-of-gravity transfer of his own body, the center-of-gravity moving device 2 is further designed as, as Figure 6 Schematic diagram of the bottom view of the arc-shaped swing plate shown in Figure 7Schematic diagram of the structure of the shown outer shell bottom plate. The arc swing plate 4 includes a flat pedal 10 and an arc plate 11. The flat pedal 10 is fixedly connected to the arc plate 11. The flat pedal 10 is located above the arc plate 11. The upper plate surface 12 of the flat pedal 10 is flat, and the lower arc bottom surface 13 of the arc plate 11 is an arc surface. The lower arc bottom surface 13 of the arc plate 11 is in line contact with the upper contact surface 14 of the bottom plate 9 of the outer shell 1; the swing amplitude indicating needle 5 is arranged at the position of the first left-right bisector 15 of the flat pedal 10. The distance from the first left-right bisector 15 to the left edge 16 of the arc swing plate 4 is equal to the distance from the first left-right bisector 15 to the right edge 17 of the arc swing plate 4; the distance from the second left-right bisector 18 of the lower arc bottom surface 13 to the left edge 16 of the arc swing plate 4 is equal to the distance from the second left-right bisector 18 to the right edge 17 of the arc swing plate 4. The arc surface on the left side of the second left-right bisector 18 corresponds to the arc surface on the right side; the first left-right bisector 15 of the flat pedal 10 and the second left-right bisector 18 of the lower arc bottom surface 13 are in the same plane.

The distance from the third left-right bisector 19 to the left edge 16 of the arc swing plate 4 is equal to the distance from the third left-right bisector 19 to the right edge 17 of the arc swing plate 4. The first left-right bisector 15, the second left-right bisector 18 and the third left-right bisector 19 are in the same vertical plane; the contact line between the lower arc bottom surface 13 of the arc plate 11 and the upper contact surface 14 of the bottom plate 9 is in the same vertical plane as the first left-right bisector 15, the second left-right bisector 18 and the third left-right bisector 19.

[0012] When the intelligent center-of-gravity transfer trainer is in use, the feet of the rehabilitation patient stand at symmetric positions on both sides of the first left-right bisector 15 of the flat pedal 10.

The swing amplitude indicating needle 5 provided on the arc-shaped swing plate 4 swings to the left following the arc-shaped swing plate 4. The doctor and the patient can master the situation of the patient's center-of-gravity transfer by observing the swing amplitude of the swing amplitude indicating needle 5 swinging to the left; when the center of gravity of the rehabilitation patient's body shifts to the right foot, the arc-shaped swing plate 4 swings to the right, the right edge 17 of the arc-shaped swing plate 4 drops, the left edge 16 of the arc-shaped swing plate 4 rises, and the contact line between the lower arc bottom surface 13 of the arc-shaped plate 11 and the upper contact surface 14 of the bottom plate 9 moves to the right, and the center of gravity of the patient's body shifts to the right.

The doctor and the patient can master the situation of the patient's center-of-gravity transfer by observing the swing amplitude of the swing amplitude indicating needle 5 swinging to the right.

[0013] To improve the accuracy of displaying the data of the patient's center-of-gravity transfer, the arc-shaped swing plate 4, the left gravity sensor 6 and the right gravity sensor 7 of the controller 3 are further designed such that the left gravity sensor 6 and the right gravity sensor 7 of the controller 3 are provided at corresponding positions on both sides of the first left-right bisector 15 of the flat pedal 10. There are multiple left gravity sensors 6 and right gravity sensors 7. The number of left gravity sensors 6 on the left side of the first left-right bisector 15 is the same as the number of right gravity sensors 7 on the right side of the first left-right bisector 15; the weight on the left side of the first left-right bisector 15 and the second left-right bisector 18 of the arc-shaped swing plate 4 is the same as the weight on the right side of the first left-right bisector 15 and the second left-right bisector 18 of the arc-shaped swing plate 4.

The first left gravity sensor 21, the second left gravity sensor 22, and the third left gravity sensor 23 are disposed on the left side of the third left-right bisector 19 of the bottom plate 9. The distance from the first left gravity sensor 21 to the third left-right bisector 19 is less than the distance from the second left gravity sensor 22 to the third left-right bisector 19, and the distance from the second left gravity sensor 22 to the third left-right bisector 19 is less than the distance from the third left gravity sensor 23 to the third left-right bisector 19. The center lines of the first left gravity sensor 21, the second left gravity sensor 22, and the third left gravity sensor 23 are on the same straight line. The center lines of the first left gravity sensor 21, the second left gravity sensor 22, and the third left gravity sensor 23 are perpendicular to the third left-right bisector 19. The height of the detection surfaces of the first left gravity sensor 21, the second left gravity sensor 22, and the third left gravity sensor 23 is greater than the height of the upper contact surface 14 of the bottom plate 9; The right gravity sensor 7 includes a first right gravity sensor 24, a second right gravity sensor 25, and a third right gravity sensor 26. The first right gravity sensor 24, the second right gravity sensor 25, and the third right gravity sensor 26 are disposed on the right side of the third left-right bisector 19 of the bottom plate 9. The distance from the first right gravity sensor 24 to the third left-right bisector 19 is less than the distance from the second right gravity sensor 25 to the third left-right bisector 19, and the distance from the second right gravity sensor 25 to the third left-right bisector 19 is less than the distance from the third right gravity sensor 26 to the third left-right bisector 19.

The height of the detection surfaces of the first right gravity sensor 24, the second right gravity sensor 25, and the third right gravity sensor 26 is greater than the height of the upper contact surface 14 of the bottom plate 9.

[0015] When the intelligent center of gravity transfer trainer is in use, the feet of the rehabilitation patient stand at symmetric positions on both sides of the first left-right bisector 15 of the flat pedal 10; when the center of gravity of the rehabilitation patient's body shifts to the left foot, the arc swing plate 4 swings to the left, and the contact line between the lower arc bottom surface 13 of the arc plate 11 and the upper contact surface 14 of the bottom plate 9 moves to the left. When the lower arc bottom surface 13 of the arc plate 11 presses on the first left gravity sensor 21 provided on the bottom plate 9, the first left gravity sensor 21 transmits the data it detects to the controller 3, and the controller 3 transmits this data to the display 8, and the display 8 shows the data of the patient's center of gravity shifting to the left; as the patient's center of gravity continues to shift to the left, when the lower arc bottom surface 13 of the arc plate 11 presses on the second left gravity sensor 22 provided on the bottom plate 9, the second left gravity sensor 22 transmits the data it detects to the controller 3, and the controller 3 transmits this data to the display 8, and the display 8 shows the data of the patient's center of gravity shifting to the left; as the patient's center of gravity continues to shift to the left, when the lower arc bottom surface 13 of the arc plate 11 presses on the third left gravity sensor 23 provided on the bottom plate 9, the third left gravity sensor 23 transmits the data it detects to the controller 3, and the controller 3 transmits this data to the display 8, and the display 8 shows the data of the patient's center of gravity shifting to the left; the doctor and the patient observe the data of the patient's center of gravity shifting to the left through the display 8; When the center of gravity of the rehabilitation patient's body shifts to the right foot, the arc swing plate 4 swings to the right, and the contact line between the lower arc bottom surface 13 of the arc plate 11 and the upper contact surface 14 of the bottom plate 9 moves to the right. When the lower arc bottom surface 13 of the arc plate 11 presses on the first right gravity sensor 24 provided on the bottom plate 9, the first right gravity sensor 24 transmits the data it detects to the controller 3, and the controller 3 transmits this data to the display 8, and the display 8 shows the data of the patient's center of gravity shifting to the right; as the patient's center of gravity continues to shift to the right, when the lower arc bottom surface 13 of the arc plate 11 presses on the second right gravity sensor 25 provided on the bottom plate 9, the second right gravity sensor 25 transmits the data it detects to the controller 3, and the controller 3 transmits this data to the display 8, and the display 8 shows the data of the patient's center of gravity shifting to the right; as the patient's center of gravity continues to shift to the right, when the lower arc bottom surface 13 of the arc plate 11 presses on the third right gravity sensor 26 provided on the bottom plate 9, the third right gravity sensor 26 transmits the data it detects to the controller 3, and the controller 3 transmits this data to the display 8, and the display 8 shows the data of the patient's center of gravity shifting to the right; the doctor and the patient observe the accurate gravity data of the patient's center of gravity shifting to the left and to the right through the display 8, providing a basis for the patient's rehabilitation physiotherapy.

[0016] In order to implement the display of the weight and movement ratio of the patient's center of gravity transfer, the display window 27 is provided with a swing amplitude scale 28. The swing amplitude scale 28 includes a left transfer scale 29, a center position 20, and a right transfer scale 30. The left transfer scale 29 and the right transfer scale 30 are symmetrically arranged on both sides of the center position 20. The left transfer scale 29 is located on the left side of the center position 20, and the right transfer scale 30 is located on the right side of the center position 20. When the center of gravity movement device 2 is in the initial state, the swing amplitude indicating needle 5 points to the center position 20. The left transfer scale 29 includes weight data or swing amplitude percentage data.

[0017] When the intelligent center of gravity transfer trainer is in use, when the center of gravity of the rehabilitation patient's body shifts to the left foot, the arc swing plate 4 swings to the left, and the swing amplitude indicating needle 5 swings from the position pointing to the center position 20 to the position of the left transfer scale 29 on the left. When the left edge 16 of the arc swing plate 4 contacts the upper contact surface 14 of the bottom plate 9, the arc swing plate 4 swings to the left limit, and the arc swing plate 4 stops swinging to the left. The swing amplitude indicating needle 5 follows the arc swing plate 4 and swings to the maximum swing amplitude position of the left transfer scale 29. After the swing amplitude indicating needle 5 swings to the maximum swing amplitude position of the left transfer scale 29, when the center of gravity of the rehabilitation patient's body shifts to the right, the swing amplitude indicating needle 5 swings from the position of the left transfer scale 29 to the center position 20 for reset. When the center of gravity of the rehabilitation patient's body continues to move to the right from the center position 20, the swing amplitude indicating needle 5 swings from the center position 20 to the position of the right transfer scale 30. When the right edge 17 of the arc swing plate 4 contacts the upper contact surface 14 of the bottom plate 9, the arc swing plate 4 swings to the right limit, and the arc swing plate 4 stops swinging to the right. The swing amplitude indicating needle 5 follows the arc swing plate 4 and swings to the maximum swing amplitude position of the right transfer scale 30. When the center of gravity of the rehabilitation patient's body shifts to the left, the swing amplitude indicating needle 5 swings from the position of the right transfer scale 30 to the center position 20 for reset. This cycle continues until the training ends. The doctor and the rehabilitation patient can master the weight of the center of gravity transfer or the ratio of the transferred weight through the swing amplitude of the swing amplitude indicating needle 5 in the display window 27.

[0018] To prevent items from falling into the gap between the arc swing plate 4 and the bottom plate 9 of the housing 1, which may hinder the swing of the arc swing plate 4, and to prevent hands and feet from reaching into the gap between the arc swing plate 4 and the bottom plate 9 of the housing 1 and being pinched. Figure 8Schematic structural diagram of the pinch protection device. The center of gravity moving device 2 includes a pinch protection device 31. The pinch protection device 31 includes a left sliding plate 32, a right sliding plate 33, a left spring 34 and a right spring 35. The left sliding plate 32 is arranged on the left side of the housing 1. The left guard plate 36 of the left sliding plate 32 is in close contact with the left edge 16 of the arc-shaped swing plate 4. The left spring 34 is located between the left side plate 37 of the housing 1 and the left guard plate 36. The right sliding plate 33 is arranged on the right side of the housing 1. The right guard plate 38 of the right sliding plate 33 is in close contact with the right edge 17 of the arc-shaped swing plate 4. The right spring 35 is located between the right side plate 39 of the housing 1 and the right guard plate 38. There are multiple left springs 34 and right springs 35. The left spring 34 is located at the position of one-third to two-thirds of the height of the left guard plate 36, and the right spring 35 is located at the position of one-third to two-thirds of the height of the right guard plate 38.

[0019] The initial state of the pinch protection device 31 is that the left guard plate 36 of the left sliding plate 32 clamps the left edge 16 of the arc-shaped swing plate 4 under the elastic force of the left spring 34, and the right guard plate 38 of the right sliding plate 33 clamps the right edge 17 of the arc-shaped swing plate 4 under the elastic force of the right spring 35, avoiding gaps between the left guard plate 36 of the left sliding plate 32 and the left edge 16 of the arc-shaped swing plate 4, and avoiding gaps between the right guard plate 38 of the right sliding plate 33 and the right edge 17 of the arc-shaped swing plate 4.

[0020] When the intelligent center of gravity transfer trainer is in use, when the arc-shaped swing plate 4 swings and moves to the left, the arc-shaped swing plate 4 moves to the left against the elastic force of the left spring 34 and pushes the left sliding plate 32 to move to the left. The left edge 16 of the arc-shaped swing plate 4 remains in a state of being in close contact with the left guard plate 36 of the left sliding plate 32. At the same time, the right guard plate 38 of the right sliding plate 33 remains in a state of being in close contact with the right edge 17 of the arc-shaped swing plate 4 under the elastic force of the right spring 35. When the arc-shaped swing plate 4 swings and moves to the right, the arc-shaped swing plate 4 moves to the right against the elastic force of the right spring 35 and pushes the right sliding plate 33 to move to the right. The right edge 17 of the arc-shaped swing plate 4 remains in a state of being in close contact with the right guard plate 38 of the right sliding plate 33. At the same time, the left guard plate 36 of the left sliding plate 32 remains in a state of being in close contact with the left edge 16 of the arc-shaped swing plate 4 under the elastic force of the left spring 34. Thus, it effectively prevents objects and hands and feet from entering the gap between the arc-shaped swing plate 4 and the bottom plate 9 of the housing 1 from the left edge 16 or the right edge 17 of the arc-shaped swing plate 4.

[0021] To prevent the left spring 34 and the right spring 35 from pinching hands or feet, the left spring 34 and the right spring 35 are enclosed within the housing 1; the left sliding plate 32 includes a left cover plate 40 and a left slider 41. The left cover plate 40, the left guard plate 36, and the left slider 41 are integrally formed, or the left cover plate 40 is fixedly connected to the left guard plate 36, the left guard plate 36 is fixedly connected to the left slider 41, and the left cover plate 40 is movably and fittingly connected to the left side plate 37 of the housing 1; the right sliding plate 33 includes a right cover plate 42 and a right slider 43. The right cover plate 42, the right guard plate 38, and the right slider 43 are integrally formed, or the right cover plate 42 is fixedly connected to the right guard plate 38, the right guard plate 38 is fixedly connected to the right slider 43, and the right cover plate 42 is movably and fittingly connected to the right side plate 39 of the housing 1; the bottom of the housing 1 is provided with a left guide groove 44 and a right guide groove 45.

[0022] To ensure the safe use of the intelligent center-of-gravity transfer trainer, the left cover plate 40 is used to cover the left spring 34, and the right cover plate 42 is used to cover the right spring 35. When the arc-shaped swing plate 4 is in the initial state, the swing amplitude indicating needle 5 points to the central position 20; the leftward movement stroke of the arc-shaped swing plate 4 is the same as the rightward movement stroke of the arc-shaped swing plate 4; when the arc-shaped swing plate 4 is in the initial state, the distance from the left side plate 37 of the housing 1 to the left edge 46 of the left cover plate 40 is greater than or equal to the maximum rightward movement stroke of the left sliding plate 32; the distance from the right side plate 39 of the housing 1 to the right edge 47 of the right cover plate 42 is greater than or equal to the maximum leftward movement stroke of the right sliding plate 33.

[0023] When the intelligent center-of-gravity transfer trainer is in use, when the center of gravity of the rehabilitation patient's body moves to the left, the arc-shaped swing plate 4 swings to the left against the elastic force of the left spring 34. The arc-shaped swing plate 4 pushes the left cover plate 40 of the left sliding plate 32 to move to the left, and the left cover plate 40 moves to the left along the left side plate 37 of the housing 1, and the left cover plate 40 and the left side plate 37 of the housing 1 remain in a tightly contacting state; at the same time, the right sliding plate 33 moves to the left under the action of the right spring 35, and the right cover plate 42 of the right sliding plate 33 remains in a state of covering the right side plate 39 of the housing 1; when the center of gravity of the rehabilitation patient's body moves to the right, the arc-shaped swing plate 4 swings to the right against the elastic force of the right spring 35. The arc-shaped swing plate 4 pushes the right cover plate 42 of the right sliding plate 33 to move to the right, and the right cover plate 42 moves to the right along the right side plate 39 of the housing 1, and the right cover plate 42 and the right side plate 39 of the housing 1 remain in a tightly contacting state; at the same time, the left sliding plate 32 moves to the right under the action of the left spring 34, and the left cover plate 40 of the left sliding plate 32 remains in a state of covering the left side plate 37 of the housing 1; so as to achieve the purpose of using the left cover plate 40 and the right cover plate 42 to cover the left spring 34 and the right spring 35.

[0024] To implement the detection of the proportion of the patient's center of gravity shift, the controller 3 includes a center position sensor 48, a center position sensing element 49, a left distance sensor 50, and a right distance sensor 51; the center position sensing element 49 is provided at the center position of the arc-shaped swing plate 4, the center position sensor 48 is provided on the front plate 52 of the housing 1 corresponding to the center position of the arc-shaped swing plate 4, the left distance sensor 50 is provided at the left end 53 of the arc-shaped swing plate 4, the detection head of the left distance sensor 50 points to the bottom plate 9 of the housing 1, the right distance sensor 51 is provided at the right end 54 of the arc-shaped swing plate 4, the detection head of the right distance sensor 51 points to the bottom plate 9 of the housing 1, and the controller 3 is connected to the center position sensor 48, the left distance sensor 50, and the right distance sensor 51 through control lines.

[0025] The distance between the left distance sensor 50 on the left end 53 of the arc-shaped swing plate 4 and the bottom plate 9 of the housing 1 is inversely proportional to the gravity of the left shift of the human center of gravity on the arc-shaped swing plate 4. The smaller the distance between the left distance sensor 50 on the left end 53 of the arc-shaped swing plate 4 and the bottom plate 9 of the housing 1, the greater the gravity of the human center of gravity on the arc-shaped swing plate 4 shifting to the left foot, and the greater the proportion of the left shift of the human center of gravity; the distance between the right distance sensor 51 on the left end 53 of the arc-shaped swing plate 4 and the bottom plate 9 of the housing 1 is inversely proportional to the gravity of the right shift of the human center of gravity on the arc-shaped swing plate 4. The smaller the distance between the right distance sensor 51 on the right end 54 of the arc-shaped swing plate 4 and the bottom plate 9 of the housing 1, the greater the gravity of the human center of gravity on the arc-shaped swing plate 4 shifting to the right foot, and the greater the proportion of the right shift of the human center of gravity.

[0026] To display the data of the patient's human center of gravity shift, the display 8 of the controller 3 includes a center position display frame 55, a first left center of gravity shift display frame 56, a second left center of gravity shift display frame 57, a third left center of gravity shift display frame 58, a first right center of gravity shift display frame 59, a second right center of gravity shift display frame 60, a third right center of gravity shift display frame 61, a left shift proportion display frame 62, and a right shift proportion display frame 63.

[0027] On the flat pedal 10 of the arc-shaped swing plate 4, there are a left footprint 64 and a right footprint 65, and in front of the left footprint 64 and the right footprint 65, there is a raised front baffle 72 for facilitating the positioning of the patient's feet.

[0028] When the intelligent center-of-gravity transfer trainer is in use, after the start switch of the controller 3 is turned on, in the initial state of the intelligent center-of-gravity transfer trainer, the center position sensor 49 on the arc swing plate 4 approaches the center position sensor 48 on the front plate 52 of the housing 1. The center position sensor 48 transmits its signal to the controller 3, and the controller 3 controls the center position display frame 55 of the display 8 to display that the intelligent center-of-gravity transfer trainer is in the center position; after the left foot and the right foot of the rehabilitation patient step on the left footprint 64 and the right footprint 65 symmetrically on the flat pedal 10 of the arc swing plate 4 respectively, the patient controls the swing of the arc swing plate 4 with the left foot and the right foot under the guidance of the doctor; when the arc swing plate 4 swings to the left and presses on the first left gravity sensor 21, the first left gravity sensor 21 transmits its signal to the controller 3, and the controller 3 controls the first center-of-gravity left transfer display frame 56 of the display 8 to display the gravity data of the center-of-gravity left transfer of the rehabilitation patient; when the arc swing plate 4 swings to the left and presses on the second left gravity sensor 22, the second left gravity sensor 22 transmits its signal to the controller 3, and the controller 3 controls the second center-of-gravity left transfer display frame 57 of the display 8 to display the gravity data of the center-of-gravity left transfer of the rehabilitation patient; when the arc swing plate 4 swings to the left and presses on the third left gravity sensor 23, the third left gravity sensor 23 transmits its signal to the controller 3, and the controller 3 controls the third center-of-gravity left transfer display frame 58 of the display 8 to display the gravity data of the center-of-gravity left transfer of the rehabilitation patient; the distance that the left distance sensor (50) on the arc swing plate 4 moves downward towards the bottom plate 9 of the housing 1 is proportional to the gravity exerted by the patient's left foot, and the proportion of the patient's center-of-gravity left transfer is proportional to the distance that the left distance sensor 50 moves downward towards the housing 1; while the arc swing plate 4 swings to the left, the left distance sensor 50 at the left end 53 of the arc swing plate 4 transmits the distance data between it and the bottom plate 9 of the housing 1 to the controller 3, and the controller 3 controls the left transfer proportion display frame 62 to display the proportion of the patient's center-of-gravity left transfer; for example, when the patient is not standing on the arc swing plate 4 in the initial state, the proportion of the center-of-gravity left transfer is zero, and when the arc swing plate 4 swings downward and its left end 53 touches the bottom plate 9 of the housing 1, the proportion of the center-of-gravity left transfer is the maximum value.

[0029] When the arc swing plate 4 swings to the right and presses against the first right gravity sensor 24, the first right gravity sensor 24 transmits its signal to the controller 3. The controller 3 controls the center of gravity of the display 8 to shift to the right, and the first display frame 59 displays the gravity data of the center of gravity shift to the right of the rehabilitation patient. When the arc swing plate 4 swings to the right and presses against the second right gravity sensor 25, the second right gravity sensor 25 transmits its signal to the controller 3. The controller 3 controls the center of gravity of the display 8 to shift to the right, and the second display frame 60 displays the gravity data of the center of gravity shift to the right of the rehabilitation patient. When the arc swing plate 4 swings to the right and presses against the third right gravity sensor 26, the third right gravity sensor 26 transmits its signal to the controller 3. The controller 3 controls the center of gravity of the display 8 to shift to the right, and the third display frame 61 displays the gravity data of the center of gravity shift to the right of the rehabilitation patient. The distance that the right distance sensor 51 on the arc swing plate 4 moves downward toward the bottom plate 9 of the housing 1 is proportional to the gravity exerted by the patient's right foot. The proportion of the patient's center of gravity shift to the right is proportional to the distance that the right distance sensor 51 moves downward toward the housing 1. While the arc swing plate 4 swings to the right, the right distance sensor 51 at the right end 54 of the arc swing plate 4 transmits the distance data between it and the bottom plate 9 of the housing 1 to the controller 3. The controller 3 controls the right shift ratio display frame 63 to display the proportion of the patient's center of gravity shift to the right. For example, in the initial state when the patient has not stepped onto the arc swing plate 4, the proportion of the center of gravity shift to the left is zero. When the arc swing plate 4 swings downward and its right end 54 contacts the bottom plate 9 of the housing 1, the proportion of the center of gravity shift to the right is at its maximum value.

[0030] The housing 1 is provided with a bracket 67, and the bracket 67 is provided with a handle 68. When the rehabilitation patient is unsteady, the patient can hold the handle 68 on the bracket 67 with both hands. The height of the handle 68 is such that when the patient stands on the arc swing plate 4, it is easy for the patient to reach the handle 68 with both hands, preventing the rehabilitation patient from falling. The height of the arc swing plate 4 is about 8 to 12 centimeters to facilitate the patient to step onto the arc swing plate 4.

[0031] To ensure the stable swing of the arc swing plate 4, the front vertical surface 69 and the rear vertical surface 70 of the arc swing plate 4 are parallel to each other, and the front vertical surface 69 and the rear vertical surface 70 are perpendicular to the horizontal ground. The front plate 52 and the rear plate 71 of the housing 1 are parallel to each other, and the front plate 52 and the rear plate 71 are perpendicular to the horizontal ground.
