Description

Technical Field

[0001] The utility model relates to a rehabilitation device for patients after illness, in particular to a center of gravity transfer trainer. Background Art

[0002] At present, after many stroke patients or other disease patients 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.; currently, for the center of gravity transfer training of patients, one or two weighing scales are used. Its defect is that the weighing scale can not only not visually display the quantification of the patient's center of gravity transfer, and the visual feedback of the center of gravity transfer to the patient is poor, but also neither the patient nor the doctor can directly see whether the patient's center of gravity has been transferred to the central axis of the patient's body from the data of one or two weighing scales, and even less can visually observe the process of the human center of gravity transferring from the left to the balance point and then to the right, affecting the training effect of the patient's center of gravity transfer; a center of gravity transfer trainer has become a need for the rehabilitation training of the patient's center of gravity transfer. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a brand-new center of gravity transfer trainer for the rehabilitation training of the center of gravity transfer of stroke patients or other disease patients, solve the problem that the weighing scale for center of gravity transfer training cannot visually observe the process of the human center of gravity transferring from the left to the balance point and then to the right, and improve the training effect of the center of gravity transfer.

[0004] The technical solution adopted by the utility model is: 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 of the balance training board 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.

[0005] During the rehabilitation training of the rehabilitation patient, place the center of gravity transfer trainer on a flat ground, let the rehabilitation patient stand on the balance training board with both feet, use both feet to control the swing of the balance training board, use the balance indicating needle to display the process of the patient's center of gravity movement, indicate the patient's center of gravity movement situation and the balance of both feet's force through the balance indicating needle, use the balance indicating needle to guide the two feet of the rehabilitee to exert force, use the two feet to overcome the elastic force of the left spring or the right spring, adjust the balance training board to be parallel to the ground or the horizontal line, train the two feet of the rehabilitee to balance the force, and gradually restore the two feet of the rehabilitee to the state of balanced force.

[0006] In order to enable doctors and patients to clearly see the patient's center of gravity transfer, a quantitative indication of the patient's center of gravity transfer is implemented. The number or proportion of the patient's center of gravity transfer is displayed through the swing amplitude of the balance training board, so that both doctors and patients can intuitively see whether the patient's center of gravity has transferred to a balanced state; the outer shell is provided with a transparent center of gravity transfer indication window, and the balance indicating needle is located below the center of gravity transfer indication window. The center of gravity transfer indication window is provided with a center of gravity transfer marking scale, and the center of gravity transfer marking scale is provided with a zero position balance point mark; the initial state of the balance indicating needle of the center of gravity transfer trainer is that the board surface of the balance training board is parallel to the ground or the board surface of the balance training board is parallel to the horizontal line, and the balance indicating needle is aligned with the zero position balance point mark of the center of gravity transfer marking scale, that is, the balance training board is in a balanced state.

[0007] During the rehabilitation training of rehabilitation patients, the patient's feet stand on both sides of the balance training board respectively. When the forces exerted by the patient's two feet are unbalanced, the balance training board will tilt, causing the balance indicating needle to deviate from the position where it is aligned with the zero position balance point mark in the middle of the center of gravity transfer marking scale; the doctor guides the patient to exert force on the left foot or right foot according to the patient's condition, controls and adjusts the balance training board to return to a balanced state, makes the balance training board parallel to the ground, and judges whether the patient's center of gravity has transferred to the patient's body axis and whether the forces exerted by the patient's two feet are balanced by whether the balance indicating needle is aligned with the zero position balance point mark of the center of gravity transfer marking scale. The patient is guided to exert force on both feet through the center of gravity transfer marking scale, so that the forces exerted by the patient's two feet gradually return to the normal state of balanced force.

[0008] The beneficial effects of the present utility model are as follows: When the patient is training the center of gravity transfer, the patient stands on both sides of the balance training board, and the doctor guides the patient to train according to the patient's condition. The balance indicating needle is used to intuitively display the patient's center of gravity transfer situation, allowing the patient to visually see the data of their own center of gravity transfer. By observing whether the balance indicating needle is aligned with the zero position balance point mark in the middle, the patient can clearly know whether their center of gravity is on the body axis, enabling the patient to better cooperate with the doctor in training and improving the effect of the center of gravity transfer training; it solves the defect that neither the patient nor the doctor can intuitively see whether the patient's center of gravity has transferred to the patient's body axis from the data of one or two weighing scales, solves the problem that the weighing scale cannot visually observe the center of gravity transfer of the human body during the center of gravity transfer training, solves the problem that the weighing scale cannot visually observe the process of the human body's center of gravity transferring from the left to the balance point and then to the right, or solves the problem that the weighing scale cannot visually observe the process of the human body's center of gravity transferring from the right to the balance point and then to the left.

[0015] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0016] As Figure 1 Schematic diagram of the structure of the center of gravity transfer trainer shown, Figure 2 shown Figure 1 Top view, Figure 3 shown Figure 1 Left view; The center of gravity transfer trainer includes a balance training board 1, a housing 2, a left spring 3, a right spring 4 and a balance indicating needle 5. The balance training board 1 is hinged to the housing 2. The left spring 3 and the right spring 4 are arranged in the housing 2. The left spring 3 and the right spring 4 are located below the balance training board 1. The left spring 3 and the right spring 4 are respectively on both sides of the hinge axis 6 of the balance training board 1. The hinge axis 6 is located in the middle of the balance training board 1. The balance indicating needle 5 is connected to the balance training board 1.

[0017] During the rehabilitation training of rehabilitation patients, place the center of gravity transfer trainer on a flat ground, let the rehabilitation patients stand on the balance training board 1 with both feet, use both feet to control the swing of the balance training board 1, use the balance indicating needle 5 to display the process of the patient's center of gravity movement, indicate the patient's center of gravity movement and the force balance of both feet through the balance indicating needle 5, use the balance indicating needle 5 to guide the force of the two feet of the rehabilitator, use the force of the two feet to overcome the elastic force of the left spring 3 or the right spring 4, adjust the balance training board 1 to be parallel to the ground or the horizontal line, train the balanced force of the two feet of the rehabilitator, and gradually restore the two feet of the rehabilitator to the state of balanced force.

[0018] In order for doctors and patients to clearly see the patient's center of gravity transfer, a quantitative indication of the patient's center of gravity transfer is implemented, and the quantity or proportion of the patient's center of gravity transfer is displayed by the swing amplitude of the balance training board 1; the housing 2 is provided with a transparent center of gravity transfer indication window 7, the balance indicating needle 5 is located below the center of gravity transfer indication window 7, the center of gravity transfer indication window 7 is provided with a center of gravity transfer scale 8, and the center of gravity transfer scale 8 is provided with a zero balance point mark 9; the initial state of the balance training board 1 is that the board surface 10 of the balance training board 1 is parallel to the ground, or the board surface 10 of the balance training board 1 is parallel to the horizontal line, and the balance indicating needle 5 is aligned with the zero balance point mark 9 of the center of gravity transfer scale 8.

[0019] During the rehabilitation training of a rehabilitation patient, the patient's two feet stand on both sides of the balance training board 1 respectively. When the forces exerted by the patient's two feet are unbalanced, the balance training board 1 will tilt, causing the balance indicating needle 5 to deviate from the position of aligning with the zero balance point mark 9 in the middle of the center of gravity transfer scale 8; the doctor guides the patient to exert force on the left foot or the right foot according to the patient's condition, controls and adjusts the balance training board 1 to return to the balanced state, makes the balance training board 1 parallel to the ground, and judges whether the patient's center of gravity has transferred to the patient's body axis and whether the forces exerted by the patient's two feet are balanced by whether the balance indicating needle 5 is aligned with the zero balance point mark 9 of the center of gravity transfer scale 8, and guides the patient to exert force on both feet through the center of gravity transfer scale 8, so that the forces exerted by the patient's two feet gradually return to the normal state of balanced force.

[0020] In order to enable the balance training board 1 to swing around the hinge axis 6, the balance training board 1 is provided with an upper hinge 11 and a lower hinge 12. The balance training board 1 is connected to the housing 2 through the upper hinge 11 and the lower hinge 12, and the balance indicating needle 5 is installed on the rotating shaft 36 of the upper hinge 11 of the balance training board 1; the balance indicating needle 5 is composed of a vertical connecting rod 13 and a horizontal pointer rod 14, and the vertical connecting rod 13 is fixedly connected to the rotating shaft 36 of the balance training board 1; the center of gravity transfer scale 8 is provided with a left center of gravity transfer scale 15 and a right center of gravity transfer scale 16, and the left center of gravity transfer scale 15 and the right center of gravity transfer scale 16 are respectively located on both sides of the zero balance point mark 9, and are used to mark the swinging degree of the balance training board 1.

[0021] When the balance training board 1 swings, the rotating shaft 36 rotates following the balance training board 1, and the rotation angle of the rotating shaft 36 is proportional to the swing amplitude of the balance training board 1. When the rotating shaft 36 rotates, the vertical connecting rod 13 and the horizontal pointer rod 14 swing following the rotating shaft 36, and the swinging amplitude of the vertical connecting rod 13 and the horizontal pointer rod 14 is proportional to the rotation angle of the rotating shaft 36.

[0022] When the balance training board 1 swings counterclockwise, the horizontal pointer rod 14 follows the swing of the balance training board 1. The gravity value of the left center of gravity transfer scale 15 aligned by the horizontal pointer rod 14 is the same as the pressure value of the left spring 3 applied by the patient's left foot under the balance training board 1. At this time, the gravity of the left center of gravity transfer scale 15 is the same as the elastic force value of the left spring 3, and the center of gravity of the human body transfers to the left foot of the human body; when the balance training board 1 swings clockwise, the horizontal pointer rod 14 follows the swing of the balance training board 1. The gravity value of the right center of gravity transfer scale 16 aligned by the horizontal pointer rod 14 is the same as the pressure value of the right spring 4 applied by the patient's left foot under the balance training board 1. At this time, the gravity of the right center of gravity transfer scale 16 is the same as the elastic force value of the right spring 4, and the center of gravity of the human body transfers to the right foot of the human body; the data of the balance indicating needle 5 is used to quantitatively indicate the center of gravity transfer of the patient, and the doctor and the patient can clearly see the quantitative value of the center of gravity transfer of the patient through the balance indicating needle 5.

[0023] For example, when the patient's left foot applies force to the left side of the balance training board 1 and steps on the balance training board 1 to swing counterclockwise to the gravity value of 10 kilograms on the left center of gravity transfer scale 15, the pressure applied by the balance training board 1 to the left spring 3 is 10 kilograms, and the elastic force of the left spring 3 is 10 kilograms; for example, when the patient's right foot applies force to the right side of the balance training board 1 and steps on the balance training board 1 to swing clockwise to the gravity value of 10 kilograms on the right center of gravity transfer scale 16, the pressure applied by the balance training board 1 to the right spring 4 is 10 kilograms, and the elastic force of the right spring 4 is 10 kilograms.

[0024] As Figure 4 Shown in the schematic diagram of the counterclockwise swing structure of the balance training board, during the rehabilitation training of the rehabilitation patient, the patient's left foot stands on the left side of the balance training board 1, and the patient's right foot stands on the right side of the balance training board 1. When the pressure applied by the patient's left foot to the left side of the balance training board 1 is greater than the pressure applied by the patient's right foot to the right side of the balance training board 1, the balance training board 1 overcomes the elastic force of the left spring 3 and tilts to the left, and the balance indicating needle 5 follows the balance training board 1 and swings to the left; according to the patient's situation, the doctor guides the patient to increase the pressure applied by the right foot to the right side of the balance training board 1 and at the same time reduce the pressure applied by the left foot to the left side of the balance training board 1, so that the balance training board 1 returns to the initial balanced state.

[0025] As Figure 5Schematic diagram of the counterclockwise swing structure of the balance training board shown. During the rehabilitation training of the patient, the patient's left foot stands on the left side of the balance training board 1, and the patient's right foot stands on the right side of the balance training board 1. When the pressure exerted by the patient's right foot on the right side of the balance training board 1 is greater than the pressure exerted by the patient's left foot on the left side of the balance training board 1, the balance training board 1 overcomes the elastic force of the right spring 4 and tilts to the right, and the balance indicator needle 5 swings to the right following the balance training board 1. According to the patient's condition, the doctor guides the patient to increase the pressure exerted by the left foot on the left side of the balance training board 1 and at the same time reduce the pressure exerted by the right foot on the right side of the balance training board 1, so that the balance training board 1 returns to the initial balanced state. By repeating this process continuously, the patient's two feet are trained to exert force evenly using the center of gravity transfer trainer.

[0026] In order to control the tilt angle of the balance training board 1 and prevent the balance training board 1 from tilting continuously in a linear manner, a stepped control of the tilt angle of the balance training board 1 is implemented. The balance training board 1 is supported by changing the elastic force of the left spring 3 or the right spring 4 to prevent the patient from losing weight and falling due to the continuous tilt of the balance training board 1. There are multiple left springs 3, including the first left spring 17 and the second left spring 18. The bottom plate 19 of the outer shell 2 is provided with a left positioning column 20, which is located on the left side of the bottom plate 19. The lower ends of the first left spring 17 and the second left spring 18 are installed at the position of the left positioning column 20, and the lower ends of the first left spring 17 and the second left spring 18 are connected to the left side of the bottom plate 19. The upper ends of the first left spring 17 and the second left spring 18 face the left side of the balance training board 1. There are multiple right springs 4, including the first right spring 21 and the second right spring 22. The bottom plate 19 of the outer shell 2 is provided with a right positioning column 23, which is located on the right side of the bottom plate 19. The lower ends of the first right spring 21 and the second right spring 22 are installed at the position of the right positioning column 23, and the lower ends of the first right spring 21 and the second right spring 22 are connected to the right side of the bottom plate 19. The upper ends of the first right spring 21 and the second right spring 22 face the right side of the balance training board 1.

[0027] During the rehabilitation training of a rehabilitated patient, the left foot stands on the left side of the balance training board 1, and the right foot stands on the right side of the balance training board 1, and the distance from the patient's left foot to the hinge axis 6 is equal to the distance from the right foot to the hinge axis 6; when the pressure exerted by the patient's left foot on the left side of the balance training board 1 is greater than the pressure exerted by the patient's right foot on the right side of the balance training board 1, the balance training board 1 swings counterclockwise against the elastic force of the first left spring 17, the left side of the balance training board 1 drops, and the right side of the balance training board 1 rises, and the balance indicating needle 5 swings counterclockwise following the balance training board 1, causing the horizontal pointer rod 14 of the balance indicating needle 5 to swing from the middle position facing the zero-position balance point mark 9 to the position facing the left center-of-gravity transfer scale 15; the doctor guides the patient to control the force of both feet according to the patient's condition, and controls the horizontal pointer rod 14 to swing clockwise to restore the horizontal pointer rod 14 to the initial state of aligning with the zero-position balance point mark 9.

[0028] During the rehabilitation training of a rehabilitated patient, the left foot stands on the left side of the balance training board 1, and the right foot stands on the right side of the balance training board 1, and the distance from the patient's left foot to the hinge axis 6 is equal to the distance from the right foot to the hinge axis 6; when the pressure exerted by the patient's right foot on the right side of the balance training board 1 is greater than the pressure exerted by the patient's left foot on the left side of the balance training board 1, the balance training board 1 swings clockwise against the elastic force of the first right spring 21, the right side of the balance training board 1 drops, and the left side of the balance training board 1 rises, and the balance indicating needle 5 swings clockwise following the balance training board 1, causing the horizontal pointer rod 14 of the balance indicating needle 5 to swing from the middle position facing the zero-position balance point mark 9 to the position facing the right center-of-gravity transfer scale 16; the doctor guides the patient to control the force of both feet according to the patient's condition, and controls the horizontal pointer rod 14 to swing counterclockwise to restore the horizontal pointer rod 14 to the initial state of aligning with the zero-position balance point mark 9.

[0029] In order to achieve the same supporting force on both sides of the balance training board 1 and hierarchically utilize springs with different supporting forces to support the balance training board 1; the middle bisector 24 of the bottom plate 19 and the hinge axis 6 of the balance training board 1 are in the same vertical plane, and the distance from the left positioning column 20 to the middle bisector 24 of the bottom plate 19 is equal to the distance from the right positioning column 23 to the middle bisector 24 of the bottom plate 19; the first left spring 17 is sleeved outside the left positioning column 20, the second left spring 18 is sleeved outside the first left spring 17, and the height of the first left spring 17 is greater than the height of the second left spring 18; the first right spring 21 is sleeved outside the right positioning column 23, the second right spring 22 is sleeved outside the first right spring 21, and the height of the first right spring 21 is greater than the height of the second right spring 22; the height of the first left spring 17 is the same as the height of the first right spring 21, the wire diameter of the first left spring 17 is the same as the wire diameter of the first right spring 21, and the elastic force of the first left spring 17 is the same as the elastic force of the first right spring 21; the height of the second left spring 18 is the same as the height of the second right spring 22, the wire diameter of the second left spring 18 is the same as the wire diameter of the second right spring 22, and the elastic force of the second left spring 18 is the same as the elastic force of the second right spring 22.

[0030] The initial state of the center of gravity transfer trainer is: the upper end of the first left spring 17 contacts the left side of the balance training board 1, and the upper end of the first right spring 21 contacts the right side of the balance training board 1; the upper end of the second left spring 18 does not contact the left side of the balance training board 1, and the upper end of the second right spring 22 does not contact the right side of the balance training board 1; the elastic force exerted by the upper end of the first left spring 17 on the left side of the balance training board 1 is the same as the elastic force exerted by the upper end of the first right spring 21 on the right side of the balance training board 1.

[0031] In order to better display the swing of the balance training board 1 and the data of the patient's center of gravity transfer of the human body, the left center of gravity transfer scale 15 includes a first left center of gravity transfer scale 25 and a second left center of gravity transfer scale 26, and the second left center of gravity transfer scale 26 is located on the left side of the first left center of gravity transfer scale 25; the right center of gravity transfer scale 16 includes a first right center of gravity transfer scale 27 and a second right center of gravity transfer scale 28, and the second right center of gravity transfer scale 28 is located on the right side of the first right center of gravity transfer scale 27; it is used to indicate the force conditions of the left foot and the right foot of the patient, or to indicate the non-equilibrium ratio of the balance training board 1.

[0032] During the rehabilitation training of a rehabilitated patient, when the pressure exerted by the patient's left foot on the left side of the balance training board 1 is greater than the pressure exerted by the patient's right foot on the right side of the balance training board 1, the balance training board 1 swings counterclockwise against the elastic force of the first left spring 17. As the left side of the balance training board 1 continuously drops, the first left spring 17 is continuously compressed. When the height of the first left spring 17 is compressed to the same height as that of the second left spring 18, the left side of the balance training board 1 contacts the second left spring 18. As the force exerted by the left foot continuously increases, the first left spring 17 and the second left spring 18 are simultaneously continuously compressed. At the same time, the balance indicating needle 5 swings counterclockwise following the balance training board 1, causing the horizontal pointer rod 14 of the balance indicating needle 5 to swing from the middle position facing the zero-position balance point mark 9 through the first left center-of-gravity transfer scale 25 to the second left center-of-gravity transfer scale 26, using the balance indicating needle 5 to display the force exerted by the left foot and the left shift of the patient's center of gravity; the doctor guides the patient's right foot to exert force according to the patient's condition, controls the right shift of the patient's center of gravity, causing the horizontal pointer rod 14 to swing clockwise and restoring the horizontal pointer rod 14 to the initial state of aligning with the zero-position balance point mark 9.

[0033] During the rehabilitation training of a rehabilitated patient, when the pressure exerted by the patient's right foot on the right side of the balance training board 1 is greater than the pressure exerted by the patient's left foot on the right side of the balance training board 1, the balance training board 1 swings clockwise against the elastic force of the first right spring 21. As the right side of the balance training board 1 continuously drops, the first right spring 21 is continuously compressed. When the height of the first right spring 21 is compressed to the same height as that of the second right spring 22, the right side of the balance training board 1 contacts the second right spring 22. As the force exerted by the right foot continuously increases, the first right spring 21 and the second right spring 22 are simultaneously continuously compressed. At the same time, the balance indicating needle 5 swings clockwise following the balance training board 1, causing the horizontal pointer rod 14 of the balance indicating needle 5 to swing from the middle position facing the zero-position balance point mark 9 through the first right center-of-gravity transfer scale 27 to the second right center-of-gravity transfer scale 28, using the balance indicating needle 5 to display the force exerted by the right foot and the right shift of the patient's center of gravity; the doctor guides the patient's left foot to exert force according to the patient's condition, controls the left shift of the patient's center of gravity, causing the horizontal pointer rod 14 to swing counterclockwise and restoring the horizontal pointer rod 14 to the initial state of aligning with the zero-position balance point mark 9.

[0034] When the balance training board 1 swings counterclockwise, the swing amplitude of the balance training board 1 is proportional to the pressure exerted by the patient's left foot on the balance training board 1. The greater the pressure exerted by the patient's left foot on the balance training board 1, the greater the swing amplitude of the balance training board 1. When the balance training board 1 swings clockwise, the swing amplitude of the balance training board 1 is proportional to the pressure exerted by the patient's right foot on the balance training board 1. The greater the pressure exerted by the patient's right foot on the balance training board 1, the greater the swing amplitude of the balance training board 1. When the pressure exerted by the patient's left foot on the balance training board 1 is the same as the pressure exerted by the patient's right foot on the balance training board 1, the balance training board 1 is in a balanced state, and the horizontal pointer rod 14 aligns with the zero-position balance point mark 9. When the balance training board 1 swings counterclockwise, the swing amplitude of the balance training board 1 is inversely proportional to the elastic force of the left spring 3. As the swing amplitude of the balance training board 1 continuously increases, the supporting force of the left spring 3 continuously increases, and the force exerted by the patient's left foot on the balance training board 1 continuously increases. When the balance training board 1 swings clockwise, the swing amplitude of the balance training board 1 is inversely proportional to the elastic force of the right spring 4. As the swing amplitude of the balance training board 1 continuously increases, the supporting force of the right spring 4 continuously increases, and the force exerted by the patient's right foot on the balance training board 1 continuously increases.

[0035] To prevent the human fingers from being pinched by the balance training board 1 and the outer shell 2, the gap between the balance training board 1 and the outer shell 2 is smaller than the size of a finger, and the gap between the balance training board 1 and the outer shell 2 is 2 millimeters to 5 millimeters. The left side plate 29 of the outer shell 2 is arc-shaped, and the left side plate 29 is movably connected to the left edge 30 of the balance training board 1. The right side plate 31 of the outer shell 2 is arc-shaped, and the right side plate 31 is movably connected to the right edge 32 of the balance training board 1.

[0036] To control the inclination angle of the balance training board 1, prevent the balance training board 1 from tilting excessively, prevent the patient from falling, and prevent the balance training board 1 from pinching the hands and feet of other people. The outer shell 2 is provided with a left limit plate 33 and a right limit plate 34. The left limit plate 33 is located below the left edge 30 of the balance training board 1, and the right limit plate 34 is located below the right edge 32 of the balance training board 1. The balance training board 1 is provided with a lining plate 35, and the height of the lining plate 35 is greater than the swing height of the balance training board 1.

[0037] When the balance training board 1 swings counterclockwise and the lower left part 37 of the liner 35 on the left edge 30 of the balance training board 1 contacts the left limit plate 33, the balance training board 1 is blocked by the left limit plate 33 and stops swinging. When the balance training board 1 stops swinging, the lower left part 37 of the liner 35 of the balance training board 1 swings to the lowest position. At the same time, the lower right part 38 of the liner 35 on the right edge 32 of the balance training board 1 swings to the highest position. When the lower right part 38 of the liner 35 on the right edge 32 of the balance training board 1 swings to the highest position, the gap between the lower left part 37 of the liner 35 of the balance training board 1 and the outer shell 2 is smaller than the size of a finger, preventing the finger from being pinched by the balance training board 1 and the outer shell 2. When the balance training board 1 swings clockwise and the lower right part 38 of the liner 35 on the right edge 32 of the balance training board 1 contacts the right limit plate 34, the balance training board 1 is blocked by the right limit plate 34 and stops swinging. When the balance training board 1 stops swinging, the lower right part 38 of the liner 35 of the balance training board 1 swings to the lowest position. At the same time, the lower left part 37 of the liner 35 on the left edge 30 of the balance training board 1 swings to the highest position. When the lower left part 37 of the liner 35 on the left edge 30 of the balance training board 1 swings to the highest position, the gap between the lower left part 37 of the liner 35 of the balance training board 1 and the outer shell 2 is smaller than the size of a finger, preventing the finger from being pinched by the balance training board 1 and the outer shell 2.

[0038] To facilitate the patient to stand on the balance training board 1, a left foot mark 39 is provided on the left side of the balance training board 1, and a right foot mark 40 is provided on the right side of the balance training board 1. The distance from the left foot mark 39 to the hinge axis 6 is equal to the distance from the right foot mark 40 to the hinge axis 6.
