Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device that is worn on the body of a person with a walking disability, and generates intermittent rhythmic sounds at regular intervals and spot-like or horizontal line-shaped irradiation light that is irradiated in front of the feet of the person with a walking disability. This invention relates to a training device that trains walking by giving feedback through auditory and visual feedback, and improves walking behavior such as forward and backward step length, left and right step length, cadence, and walking speed.

Diseases of the central nervous system include hemiplegia, Parkinson's disease, dystonia, and senile dementia. People with walking disabilities due to these diseases can be trained to return to the normal gait of a healthy person through gait training. This can be improved by getting closer to the customer who is being treated.

Conventionally, as a means of improving pedestrian performance, the subject's walking process was photographed using a camera, and each frame of the photographic film was reproduced, broken down into details, and appropriate instructions given to the subject. It's here.

Another method is to have the test subject walk on a sheet with colored soles laid out on the floor, analyze the footprints, and give instructions to improve walking. However, the above-mentioned improvement means are static improvement means that analyze data and give instructions to the experimenter, so that disabled people with reduced motor nerve function can follow the abstract instructions and independently practice walking. Improving gait is extremely difficult, and results have been limited.

The present invention eliminates the above-mentioned conventional defects, and its main points are a light emitting device that can adjust the irradiation direction and has a pointing function, and a light emitting device that can adjust the time interval and eliminates rhythm noise. An electric circuit device equipped with electric elements that generate electricity is housed in a rectangular parallelepiped-shaped cliff body, and the shade body is attached to the front of the pedestrian's abdomen, so that the disabled person can stand on the floor in front of him in the walking direction. By voluntarily walking forward while matching the pace to the irradiation target and the IJ rhythm sound, the pedestrian is dynamically trained to improve his or her own stride length, stride length, walking speed, etc. The purpose is to propose a new training device that enables reflexive learning.

An embodiment of the present invention will be described below with reference to the drawings. First, reference numeral 1 is a fan-flat, vertically elongated rectangular parallelepiped-shaped body, which is composed of a front plate 2, a rear plate 3, side plates 4, 4, a top plate 5, and a bottom plate 6. A hook-shaped retaining plate 7 is provided, a band 8 is inserted between the retaining plate 7 and the rear plate 3, and the casing 1 is attached to the front of the abdomen of a person with a walking disability, as shown in FIG.

The inside of the sparrow body 1 is divided into a lighting room 9 and a circuit room 10, and the lighting room 9 has a light emitting device 1 that illuminates the feet of a disabled person.
On the other hand, the circuit chamber 10 houses a speaker 12, a circuit device 14 for sending a desired signal to the speaker 12, and lighting the light bulb 13 in the light emitting device 11, a battery 15, and the like.

First, the illumination chamber 9 is located below the screen 1 and is formed into a rectangular shape by a front plate 2, a rear plate 3, a side plate 4, a bottom plate 6, a partition plate 16, and a bridge horizontal plate 17.

In this case, the bottom plate 6 will be formed of a transparent plate 6a, but it is also possible to leave the bottom plate 6 in the Sekiguchi state without disposing such a bottom plate 6, or even cut out the front plate 2. This is a good configuration. A light emitting device 11 is incorporated in the lighting chamber 9, and its configuration is such that a light bulb 13 is fixedly suspended from a horizontal board 17 through a socket 18, and a pair of light bulbs 13 are attached to the light bulb 13 at both ends of the bottom plate portion 19a. side slope part 19b
It is covered with a U-shaped frame 19 with an erected structure.

This frame material 19 is constructed so that the light bulb 13 is located in the center, and the upper ends of both side plates 19b are connected to the side plates 4 and the partitioning plates 16, respectively.
It is tightly pivoted through a screw pin 20 to be able to swing back and forth. A lever 21 is provided to protrude outward at an appropriate location on one side plate portion 13b of the frame member 19 on the side plate 4 side of the weight body 1, and a frame member is provided on the side plate 4 in a manner corresponding to the lever 21. Arc-shaped through hole 2 along the swing trajectory of 19
2 and pass the lever 21 through the through hole 22 to attach the cliff body 1.
Protrude laterally.

The swinging motion of the frame member 19 is obtained by operating the lever 21 from the outside, and since the frame member 19 is firmly pivoted as described above through two screw pins, the desired swing angle is obtained. It can be made to stand still. Further, a through hole 23 is bored in the center of the bottom plate portion 19a of the frame member 19, facing the tip of the light bulb 13, and a condensing lens 25 is iron-fixed to the through hole 23 via a holder 24. .

Therefore, when the light bulb 13 is turned on, the light beam passes through the condensing lens 25.
The illumination angle can be freely changed by passing through the transparent plate 6a and swinging the frame member 19 by operating the lever 21, and illuminating a spot in an appropriate position in front of the feet of the disabled person as a target point. become. Note that a cover may be placed on a part of the outer surface of the condensing lens 25 to illuminate the feet in a horizontal line instead of a spot.

Next, inside the circuit chamber 10, a large number of through holes 26 are bored in the upper part of the front plate 2 of the weight body 1, and the speakers 12 are fixed to the inner surface of the front plate 2 corresponding to the through holes 26. Furthermore, a battery 15 as a power source for the light bulb 13 and the speaker 12 is attached to the lower part of the circuit room 10.

The circuit device 14 connected to the light bulb 13 and the speaker 12 is assembled at an appropriate position in the circuit room 10.
A light bulb switch 27, an audio changeover switch 28, a variable resistor dial 29, and an earphone jack 30 are fixed to the top plate 5 of the body 1, and a charging input jack 31 is fixed to the side plate 4.

By the way, an example of a specific wiring connection procedure for the circuit device 14 is as shown in FIG.

The battery 15 is a nickel-cadmium battery, and the light bulb 13 is connected to the battery 15 through the switch 25.
The speaker 12 is connected in parallel with the light bulb 13.

That is, the two-circuit interlocking audio changeover switch 28 is capable of disconnecting and switching between bass and treble.

Moreover, the code|symbol 32 is a variable resistor for pulse frequency setting, 3
3 is a capacitor, 34 is a unijunction transistor, and 35 and 36 are amplification transistors, respectively. If you now operate the selector switch 28 and input, the variable resistor 32
The voltage between the emitter and base of the unijunction transistor 34 reaches a peak voltage determined by the voltage applied between base 2 and base 1, and the resistance between the emitter and base rapidly increases. When the capacitor 33 is turned on, the capacitor 33 is discharged.

Then, due to the discharge, the emitter and base of the junction transistor 34 are turned off again, and the same flow as described above is repeated. In this way, one pulse wave is obtained every cycle at the base of the junction transistor 34, and this pulse is applied to the bases of the transistors 35 and 36 through a resistor and amplified, and the speaker 12 or earphone is intermittently connected to the base of the transistor 34. It makes it vibrate.

In this case, if you increase the resistance by operating the dial 29 of the variable resistor 32, the charging period of the capacitor 33 will become longer, and therefore the period of the pulse wave will become longer, so the speaker 1
The utterance pitch of the second intermittent tone will become slower.

The gait training device according to the present invention has the configuration as described above.

Therefore, the weight body 1 is attached to a person with a walking disability, and the light bulb switch 2 is
7 is turned on and turned on, and the desired angle of the frame member 19 is set by appropriately operating the lever 21. Then, a predetermined area in front of the feet of the disabled person is irradiated in a spot shape or a horizontal line shape.

In addition to the above operation, the switch 28 is turned on and the sound quality of bass or treble is selected, and the variable resistor 32
By adjusting the dial 29, an intermittent rhythmic sound of a desired pitch can be obtained. According to the present invention,
By irradiating the light bulb, a target point is formed in the form of a spot or line of light at a predetermined position in front of the feet of a person with a walking disability, and the pedestrian can be improved by stepping on the target point. I can do it.

In other words, the gait with poor leg lift, which is often seen in patients with Parkinson's disease, etc. can be improved by trying to step on the irradiated light as a target point, and it is possible to correct as much as possible the imbalance in stride length caused by hemiparesis. Since the swing target during the swing phase is determined, it is possible to raise the swing high and smoothly, improving the dragging gait.Furthermore, the so-called scissoring gait, which occurs due to adductor groin syndrome, and the step length in the left and right direction can be improved. Negatives can be corrected.

Furthermore, by synchronizing the pace with rhythmic sounds that are intermittent in a regulated manner, it is possible to correct the imbalance in stance time and reduce the time lag between the left and right sides, and it is also possible to acquire a stable walking speed. .

Therefore, by changing the pitch of the IJ rhythm sound, it is possible to achieve treatment according to the patient's degree of disability. It is most desirable that walking training using the present invention be carried out using both visual and auditory methods, but depending on the degree of disability, it may be more effective to use only one or the other. Therefore, the choice should be left to the judgment of clinical physicians.

Therefore, the training device according to the present invention has a simple structure and can be mass-produced, is easy to operate, and is lightweight, so it can be used by everyone from infants to the elderly, and can be used independently through vision and hearing. The present invention is excellent and effective, as it enables voluntary training.
