Rehabilitation method using rehabilitation devices to strengthen the affected side of patients with hemiplegia

This technology is a rehabilitation device that can maximize the effect of rehabilitation exercise by checking the difference in strength between the strength before rehabilitation exercise and the strength during the rehabilitation exercise in real time for users with hemiplegia and controlling the rotation speed of the pedal unit accordingly. It is about a rehabilitation method using .

In general, stroke causes various disabilities, such as hemiplegia of one part of the body, either the upper or lower extremities, loss of sensation on one side, and decline in cognitive function.

Some of these stroke patients become unable to walk, and some of those who are able to walk absolutely require the help of a guardian or show abnormal walking due to muscle weakness, stiffness, or balance disorders. do.

In particular, walking ability is an important issue that can determine the remaining quality of life of patients with hemiplegia due to stroke, and various studies and efforts have been made to make walking training more effective in rehabilitation treatment.

One of the most commonly used treatments for patients who are unable to walk in the early stage of stroke is treadmill walking training. In addition, when the patient's lower limb function on the affected side improves to some extent and the patient is able to stand upright, training to bear weight on the affected lower limb can be performed.

In 1994, Nugent et al. conducted weight-bearing training on stroke patients who were able to stand upright and reported that the improvement in gait was more noticeable as the number of repetitions increased.

As a rehabilitation treatment method that induces forced use of the lower extremity, such as the aforementioned treadmill walking training and weight-bearing training of the affected lower extremity, the patient for rehabilitation treatment is placed on a board as in domestic patent application No. 10-2004-001684-4. Slide board exercise for rehabilitation therapy that relieves the patient's psychological anxiety by allowing the patient to exercise in a stable position with the foot on the footrest while lying down or prone, and allows the patient to perform an exercise suitable for the patient by adjusting the inclination angle of the board. An organization has been proposed.

However, the slide board exercise equipment for rehabilitation is a structure in which both the patient's feet are supported on the foot rests as the fixing frame and the foot rest are integrated, and for the rehabilitation treatment of patients with hemiplegia, exercises that apply a load to the affected lower limb are performed. When performed, there was a problem that the patient unconsciously placed the load on the non-paralyzed side, halving the effect of the exercise.

Conventional prior art to improve this includes a base frame supported on the floor, as disclosed in Korean Patent Publication No. 10-0599467, “Device for Rehabilitation Treatment of Lower Extremities for Hemiplegia” (registration date: 2006.07.04); a lifting frame installed to be raised/lowered from the base frame to a certain height and in parallel; A variable jig that supports the lifting frame in an ascending/lowering state on an upper part of the base frame; a lifting device installed on the base frame to adjust the axial width and length of the variable jig to raise and lower the lifting frame; A pivoting coupling portion that rotates with one end of the elevating frame as a vertex is formed at an appropriate lower position, and a back plate is installed to slide up and down while the patient's upper body is supported on one upper side of the pivoting coupling portion, A table formed to form a footrest portion in which left and right footrests, which support the patient's body weight and allow the patient to stand, are installed on the lower side of the backrest in a height-adjustable state, respectively; It is configured to include a tilt adjustment device installed on the lifting frame and operating so that the table is rotated at an appropriate angle around the rotation coupling portion to stand up or lie down.

Other prior technologies related to existing hemiplegia lower extremity rehabilitation devices include, as disclosed in Korean Patent Publication No. 10-0795195 “Gait training device for hemiplegia patients” (registration date: 2008.01.09), a device that supports patients to stand upright on their own. A body formed with a plurality of support bars; A conveyor unit installed at the bottom of the body and displacing the patient's upright position while rotating by power; A motor provided on one side of the body and rotating forward and backward; and a winding roller that rotates according to the forward and reverse rotation of the motor and pulls and unwinds the wire while winding it around the outer circumference, and repeatedly pulls and unwinds the wire connected to the affected side cuff that covers the patient's affected lower extremity. , a power unit that forces the lower extremity on the affected side to move; A movement detection unit consisting of a plurality of laser sensors on one side of the body to detect the movement of the lower limbs of the patient standing upright through the conveyor unit; A control unit that controls the turning speed of the conveyor unit and the pulling and releasing of the power unit according to the signal from the movement detection unit; and a plurality of devices provided on one side of the body, displaying numerical values for controlling the turning speed of the conveyor unit and the pulling and releasing of the power unit by the control unit, so that the amount of exercise can be adjusted and the current amount of exercise can be shown according to the patient's condition. It consists of a display unit with operation buttons and a display.

However, the existing hemiplegia lower extremity rehabilitation device is designed to force rehabilitation exercise using power (rotational driving force of the motor) regardless of the user's condition (difference in muscle strength between the healthy side and the affected side) of the hemiplegic patient, so the user must check the rehabilitation status. Not only does it have the problem of being difficult to do, but it also has the problem of lowering the effort required for rehabilitation.

In order to solve the above-described conventional problems, the present invention allows the user, who is in a state of hemiparesis, to check the condition of the sound lower extremity and the affected lower extremity in advance, and then check the difference in muscle strength for the affected side, which changes in real time during rehabilitation, to determine the corresponding condition. The purpose is to provide a rehabilitation method that can practically confirm the effect of rehabilitation by proposing a device that can automatically or manually control the amount of load.

In order to solve the above-described conventional technical problems, the rehabilitation method using a rehabilitation device for strengthening the affected side of a hemiplegic patient according to the present invention is 1) rotating a pair of pedal parts (200) exposed on both sides of the body part (100).

This is characterized in that the rotation speed of the disk 120 can be controlled.

In addition, the muscle strength information in step 1) is rotation speed information of the disk 120 through the rotation detection sensor 130 when the pair of pedal units 200 rotate in a plurality of cycles, and is provided in the pedal 221. It is obtained based on at least one piece of pressure information measured by a sensor member 223, and the sensor member 223 is provided at the lower part of the pedal 221 and presses the pedal 221 through the sole of the user's foot. A lower sensor 225, which measures the pressing force applied downward, and an upper sensor 227, which is provided on the upper part of the pedal 221 and measures the pressing force applied upward to the pedal 221 through the instep of the user's foot. It is desirable to include it.

In addition, the exercise intensity required for rehabilitation exercise in step 2) is preferably set so that the load of the pedal unit 200 on the affected side is applied equally to the load of the pedal unit 200 on the unaffected side.

In addition, the speed control unit 300 is installed to be movable within the body portion 100 to face the fixing pad 310 and the fixing pad 310 that protrudes to be in contact with the outer surface of the disk 120.

Hereinafter, with reference to the attached drawings, a rehabilitation method using a rehabilitation device for strengthening the affected side of a hemiplegic patient according to the present invention (hereinafter simply referred to as 'rehabilitation method') will be described in detail.

Before explanation, please note that the affected side described below refers to the lower body of a user with paraplegia, and the healthy side refers to the lower body of a user without paraplegia.

First, as shown in Figure 1, the rehabilitation method (1) according to the present invention is largely 1) rotation of the pair of pedal parts (200) exposed on both sides of the body part (100) to the sound side and the affected side with respect to the lower limb. Step (S10) of individually acquiring muscle strength information and transmitting it to the control unit 150, 2) controlling the speed control unit 300 to determine the load of the pedal unit 200 on the healthy side and the pedal unit 200 on the affected side. Step (S20) of calculating the load amount and setting the exercise intensity required for the rehabilitation exercise (S20), and 3) checking the load amount on the pair of pedal units 200, which changes in real time during the process of performing the rehabilitation exercise, to the affected side. It includes a step (S30) of controlling the rotational speed of the pedal unit 200, which rotates by the speed control unit 300.

To explain in more detail, in order to perform step 1), the user uses a pair of pedal units 200 exposed on both sides of the body unit 100 so that the lower body of the healthy side and the affected side can be mounted in the form of riding a bicycle. Get on the saddle and rotate the pedal unit 200 in multiple cycles (for example, the pedal unit rotates once) to obtain muscle strength information on the healthy side and the affected side separately, and then transmit it to the control unit 150. Based on the muscle strength information acquired through the control unit 150, the load values for the affected and unaffected sides required for effective rehabilitation exercise are equally applied. As an example, the load values are applied to the pair of pedal units 200 through the control unit 150. It is assumed that all arbitrarily set load values are '4'.

In this process, muscle force information is transmitted to the disk through the rotation detection sensor 130 disposed in the operating space 111 inside the body 100 so as to detect the marking portion 121 provided on the outer surface of the disk 120. Muscle strength information obtained using at least one of the rotation speed information for 120 and the pressure information measured by the sensor member 223 provided on the pedal 221 will be displayed on the control unit 150 in the form of a display. make it possible

Here, the sensor member 223 provided in each pair of pedals 221 is a lower sensor 225 for measuring plantar pressure, that is, a pressing force applied downward to the pedal 221 through the sole of the user's foot, and the pedal. It is provided at the top of 221 and includes an upper sensor 227 that measures the pressure applied upward to the pedal 221 through the user's instep, and a detailed description of this will be given in the rehabilitation device 2, which will be described later. Let me explain in more detail.

Thereafter, in step 2), based on the maximum muscle strength information for the affected side, the rotation speed of the pedal unit 200 belonging to the affected side is calculated to be the same as the rotation speed of the pedal unit 200 belonging to the unaffected side. Obtained by (150) and applied to the pedal unit (200) belonging to the affected side, rehabilitation exercise is performed.

In other words, the user forcibly adjusts the load on the pedal unit 200 belonging to the affected side to maximize the effect of rehabilitation exercise on the affected side based on the muscle strength information acquired through step 1) described above, thereby controlling the load on the pedal unit 200 belonging to the affected side. By setting the same load as that of the pedal unit 200, the exercise intensity for performing rehabilitation exercise can be automatically set while the pair of pedal units 200 maintain the same rotational speed.

At this time, it is desirable to artificially adjust the load on the affected side by having the speed control unit 300, which includes the fixing pad 310 and the control pad 323, pressurize the outer surface of the disk 120 to adjust the load.

That is, with the load value (for example, set to '4') for the healthy side and the affected side in step 1) described above, the control unit 150 controls the load on the affected side based on the maximum value of the muscle strength information for the affected side. By calculating the value (for example, lowering the load value set to '4' to '1.6'), the rotation speed for the pair of pedal units 200 belonging to the healthy side and the affected side is controlled to be applied equally, and automatically Rehabilitation exercise is performed through a set exercise intensity.

Afterwards, when step 2) is completed, the load on the pair of pedal units 200, which changes in real time during the rehabilitation exercise, is confirmed through the control unit 150 in the form of a display, and the pedal unit rotates by the affected side. Step 3) is performed in which the rotation speed of 200 is controlled by the speed control unit 300.

This is especially true when the user performs rehabilitation exercises, the muscle strength of the affected side is not constant and tends to deteriorate. Through step 3), the present inventor continues the muscle strength information according to the decrease in muscle strength of the affected side and the muscle strength information on the healthy side in real time. While performing the confirmation, the user performs rehabilitation exercises while controlling the maximum load required to maintain the rotational speed of the disk 120 through the speed control unit 300 without causing strain to the body.

In this process, the load amount using the speed control unit 300 according to the rotation speed of the disk 120 is controlled by selecting an automatic mode that is automatically adjusted through an algorithm stored in the control unit 150 or by the user directly controlling the control unit 150. Allows control by selecting one of the manual modes where the load can be adjusted by operation.

Meanwhile, the rehabilitation device (2) according to the present invention, which has the form of a bicycle used in the above-described rehabilitation method (1), largely consists of a body portion (100) and a pedal portion (200), as shown in FIGS. 2 to 4. and a speed control unit 300.

In more detail, as shown in FIG. 5, the body portion 100 allows the user to ride in the form of a bicycle using the lower extremities on which the sound side and the affected side exist, and the pedal portion 200 and speed, which will be explained later, It is configured to enable rehabilitation exercise through the control unit 300, and includes a housing 110, a disk 120, a rotation sensor 130, a handle frame 141, a saddle frame 143, and a control unit 150. ) includes.

(323) is installed to move back and forth, and a detailed description of this will be given in more detail in the speed control unit 300 described later.

In addition, as shown, the disk 120 is made of a metal material and is molded to have the overall shape of a disk, and a pair of disks 120 are arranged adjacent to each other so that they can rotate within the operating space 111.

One side of the central diameter of each disk 120 is coupled to the rotating shaft member 210, and the other side is connected to the connector 231 to apply external force (for example, rolling the foot) of the user through the pedal 221. Power for rotating the disk 120 can be transmitted through rotation of the rotating shaft member 210 on the ground.

At this time, it is desirable that the rotational speed of the upper part of each disk 120 be adjusted through the generation of resistance due to the pressure of the fixing pad 310 and the control pad 323, which constitute the speed control unit 300. .

In addition, the rotation detection sensor 130 is provided with a pair of disks ( 120) is installed to face it.

At this time, it is preferable that at least one marking portion 121 sensed by the rotation detection sensor 130 is further provided on the outer surface of the disk 120, that is, the outer surface facing the rotation detection sensor 130.

In addition, the case member 140 forms the external body of the rehabilitation device 2 according to the present invention and is configured to allow the user to easily perform rehabilitation exercises while sitting in the same way as riding a bicycle. The case 145, Includes a handle frame 141 and a saddle frame 143.

The case 145 is detachably coupled through a fastening means to protect the housing 110 from the outside so that the housing 110 can be fixedly installed inside. For this purpose, the case 145 can be molded into two bodies.

At this time, there is a rotating shaft member 210 on the outside of both sides of the case 145 so that the user can sit on the saddle frame 143 and roll the pair of pedals 221 to rotate the disk 120. It is preferable that each is inserted through.

As shown, the handle frame 141 has a shape that protrudes from the front upper part of the case 145 to have a predetermined height so that the user can hold it with both hands.

Of course, although not shown, the handle frame 141 in the present invention can be molded into a telescopic type or double pipe structure so that the height of the handle can be adjusted.

Here, the saddle frame 143 can also be installed to enable height adjustment of the saddle, like the handle frame 141 described above.

In addition, the control unit 150 includes not only the rotation detection sensor 130 described above according to the present invention, but also a sensor member 223, a distortion measuring bar 235, a drive motor 237, and a servo cylinder 321 to be described later. It is provided in the form of a display between a pair of handles so that at least one of them can be electrically controlled and the user can perform rehabilitation exercises while checking the controlled situation in real time.

The control unit 150 provides convenience of input by using touch input, and allows data values for input information as well as muscle strength information and rotation speed of the disk 120 to be displayed in numbers.

In addition, the pedal unit 200 provides power to rotate the pair of discs 120 described above, and measures the muscle strength on the healthy side and the affected side to adjust the rotational speed of the disc 120 through the control unit 150. The configuration for being controlled includes a rotation axis member 210, a footrest member 220, and a muscle synchronization member 230.

For example, the rotating shaft member 210 connects the pedal 221 and the disk 120 and transmits power to rotate the disk 120 when a user performs a rolling motion by applying an external force to the pedal 221. It includes a vertical body 211 and a horizontal body 213, and as shown, the case penetrates the housing 110 to be exposed to the outside of the case 145 and can be coupled to the disk 120. (145) A pair is installed on the outside.

For this purpose, the lower part of the vertical body 211 is rotatably coupled to the pedal 221, and the upper part is rotatably coupled to one side of the horizontal body 213, and the other side of the horizontal body 213 is connected to the case 145 and the housing. It has a structure that penetrates (110) and combines with the disk (120).

In addition, the footrest member 220 rotates the above-described rotation axis member 210 through the user's external force caused by stepping on the foot, and separately detects the muscle strength of the sound side and the affected side according to the external force and transmits the detection information to the control unit 150. The configuration includes a pedal 221 and a sensor member 223.

The pedal 221 is configured to be worn by the user's feet on the sound side and the affected side, and has the same structure as the pedal provided on a normal bicycle, so detailed description will be omitted. As shown, each vertical pair consists of a pair. It is rotatably installed at the bottom of the sieve 211.

The sensor member 223 is individually installed at the lower and upper parts of each of the pedals 221 described above, detects the user's muscle strength on the healthy side and the affected side, and then transmits the sensing information to the control unit 150. ) and upper sensor 227.

Here, the lower sensor 225 is installed on the bottom surface of the pedal 221, which is in contact with the sole of the user's foot, and measures the user's plantar pressure muscle force on the sound side and the affected side applied downward to rotate the rotation axis member 210. Transmitted to the control unit 150.

As shown, the upper sensor 227 is provided on the upper part of the pedal 221, which is in contact with the user's instep, and measures the user's muscle strength on the sound side and the affected side applied upward to rotate the rotation axis member 210, and is used by the control unit. Send to (150).

In addition, the lower sensor 225 and the user's muscle strength information measured by the lower sensor 225 can be displayed in real time for the user to check.

In addition, the muscle force synchronization member 230 controls the rotational speed of the disk 120 by the control unit 150 set to manual mode or automatic mode depending on the degree of distortion that occurs according to the difference in muscle strength applied to the above-described footrest member 220. It is configured to be controlled and includes a connector 231, a distortion measuring bar 235, and a drive motor 237, and the drive motor 237 operates only when the control unit 150 is set to automatic mode. Please note that it can work.

As shown, the connector 231 is formed in the shape of a pipe with a hollow portion in the longitudinal direction, and is disposed in the operating space 111 so as to be located between a pair of disks 120, and both sides are formed with the disk 120. ) It has a structure that is connected to the outer surface and can rotate together.

As shown, the distortion measuring bar 235 is inserted into the connector 231, and is axially coupled to the outer surface of a pair of disks 120 on both sides facing each other, and is a pair of rotation axes provided on both sides of the case 145. The members 210 are configured to have a structure in which they are connected to each other.

At this time, the distortion measuring bar 235 is made of a material that can be distorted by elastic force capable of elastic restoration, but it is desirable to use a sensor that can sense the degree of distortion and then transmit the sensing information to the control unit 150. .

That is, when the user rolls the pair of pedals 221 as if riding a bicycle while wearing the foot for the sound side on one of the pair of pedals 221 and the foot for the affected side on the other, the distortion measurement bar A pair of rotating shaft members 210 and a pair of disks 120 connected to each other by (235) rotate together, and the muscle strength information is detected by the sensor member 223 and transmitted to the control unit 150 in real time. Rehabilitation exercises are performed.

In this process, the rotation speed of the rotation axis member 210 connected to the pedal 221 on the affected side decreases compared to the unaffected side, resulting in a subtle difference in the rotation speed of the pair of rotation axis members 210, which causes The rotational speed of the disk 120 as well as the elastic force cause distortion of the distortion measuring bar 235.

Thus, the control unit 150 senses the degree of distortion of the distortion measurement bar 235 in real time, and if the degree of distortion is determined to be greater than the set value stored in the control unit 150, the control unit 150 detects the muscle strength. By controlling the speed control unit 300 present on the disc 120, which is linked to the affected side, which is the fallen pedal 221, the resistance value applied to the disc 120 is reduced to relieve the muscular burden on the user, thereby reducing the burden on the affected side. This is to maximize the effectiveness of exercise.

The drive motor 237 is installed inside the case 145 and includes a chain 239 or a belt (not shown) so that it can be rotatably coupled to the outer surface of the connector 231 provided inside the operating space 111. It penetrates the housing 110 and is rotatably coupled to the outer surface of the connector 231.

Meanwhile, in the present invention, the drive motor 237 for rotating the connector 231 connected to the chain 239 to rotate the pair of disks 120 and the rotating shaft member 210 is controlled by the control unit 150. Ensure that it can be implemented through automatic mode rather than manual mode.

The operation of the drive motor 237 in this automatic mode allows users with hemiplegia to forcibly implement the effect of rehabilitation exercise through the power of the drive motor 237 in the case of a user with reduced consciousness who cannot perform the exercise alone. Therefore, it can be very useful.

In addition, the speed control unit 300 responds to the detection information of the distortion measurement bar 235 described above so that the rotation speed of each rotating disk 120 can be controlled through control of the control unit 150. It includes a fixing pad 310 and an adjustment member 320.

For example, as shown, the fixing pad 310 is fixedly installed in the groove 113 formed in the housing 110, and is preferably installed so as to be in contact with the outer surface of the disk 120.

In addition, the fixing pad 310 and the adjustment pad 323 can be made of a rubber material with high resistance to friction.

In addition, the control pad 323 is configured to reduce the rotation speed of the disk 120 by moving the control pad 323 above the fixed pad 310, and the servo cylinder 321 and the control pad 323 ) includes.

As shown, the servo cylinder 321 is inserted into the through hole 115 formed in the housing 110 so that it can be electrically connected to the control unit 150, and an adjustment pad 323 is mounted on the extensible rod end. It has a structure in which the adjustment pad 323 can be placed on one side with the disk 120 in between, and the fixing pad 310 can be placed on the other side.

At this time, the control unit 150 controls the servo cylinder 321 when the muscle strength information for the healthy side and the affected side and the rotational speed of the disk 120 by the rotation detection sensor 130 are transmitted through the above-described sensor member 223. It is desirable to perform rehabilitation exercises while controlling the affected side to have the same set value based on the set value of the healthy side.

Therefore, when the rotation speed of the disc 120 on the affected side decreases due to decreased muscle strength on the affected side in manual mode or automatic mode, the user controls the control unit 150 to apply the pressing force of the adjustment pad 323 that interviews the disc 120. In order to weaken this, a reduction in the resistance value controlling the servo cylinder 321 is implemented to realize an improvement effect through the continuity of rehabilitation exercise.
