Description

The present invention relates to a rehabilitation support device that supports rehabilitation of a patient whose hands are difficult to open due to spasticity.

Patients with neurological disorders such as stroke may have severe paralysis as a sequela. There are many patients who are restricted or have trouble with QOL (Quality of Life) due to sequelae.

During the recovery phase after treatment in the acute phase of stroke, training such as rehabilitation (hereinafter sometimes abbreviated as rehabilitation) is conducted at the hospital, but the main purpose of the hospital is to allow the patient to return home. The main training is about walking, such as being able to go to the toilet alone. With regard to upper limb paralysis, it is often the case that training is performed to make daily life independent using the upper limb on the non-paralyzed side, and there are cases where it is disused due to failure to train in the appropriate way at the appropriate time. Many have been reported.

For example, there is known a device for performing rehabilitation that can prevent contracture by sufficiently regularly training the range of motion (range of motion training) (see, for example, Patent Document 1).
The joint exercise training device and the joint exercise training method described in Patent Document 1 include a shaft portion having a central axis, a motor for rotating the shaft portion around the central axis, and grip portions having different shapes (first grip portion, first grip portion, It is provided with a plurality of holding portions each supported by a second grip portion), a connecting portion for detachably connecting the holding portion and the shaft portion, and a control unit for electrically controlling the motor. .. Further, Patent Document 1 includes a conversion unit that moves the rotation of the shaft portion in a direction orthogonal to the central axis, and converts the rotation of the shaft portion into a linear motion. , It is stated that rehabilitation of elbow flexion and extension and shoulder extension exercises can be performed.

Japanese Unexamined Patent Publication No. 2018-38881

As a sequela of a stroke or the like, for example, spasticity may cause the patient's hand to be opened but not opened. In the rehabilitation of patients with spastic hands, doctors, physiotherapists, family members, and other practitioners hold the patient's tightly closed hands, and the practitioner opens the patient's hands one by one while shaking the patient's hands up and down. It is done in the procedure.

Therefore, when the joint exercise training device described in Patent Document 1 is to be used for the rehabilitation of a patient with spastic hands, the joint exercise training device performs rehabilitation of elbow flexion / extension and shoulder extension exercise. Since it is a thing, the first grip part reciprocates greatly from side to side to the extent that the elbow extends and bends, and the side opens and closes. Therefore, it is difficult to perform training to open the fingers of the hand only by swinging the hand holding the first grip portion widely, and it is not suitable for rehabilitation of a spastic hand.

In addition, it is desirable for patients with spastic hands to perform rehabilitation every day, but daily visits to the hospital place a heavy burden on the patients. In addition, it is a heavy burden for the practitioner to perform rehabilitation for a large number of patients by holding the patient's tightly closed hand and shaking the patient's hand while opening the fingers one by one.

Therefore, an object of the present invention is to provide a rehabilitation support device capable of efficiently performing rehabilitation for a patient with spastic hands without relying on a practitioner.

The rehabilitation support device of the present invention has a rod-shaped grip portion for a patient who has difficulty opening his / her hand due to spasticity, and a drive portion that swings the grip portion in the patient's hand holding the grip portion. It is characterized by being prepared.

According to the rehabilitation support device of the present invention, first, a patient whose hands are difficult to open due to spasticity hangs the second to fifth fingers on the grip portion to grip the grip portion. Next, in the hand of the patient who grips the grip portion, the grip portion is swung by the drive unit. Then, if the patient moves the arm in the direction of opening the second to fifth fingers while the grip portion is swung, the forearm and upper arm are not pulled, and the second to fifth fingers are sequentially moved. Can be opened. Therefore, the rehabilitation support device of the present invention can be suitably used for rehabilitation in which a hand that has been firmly gripped due to spasticity is opened.

The drive unit can swing the grip portion within the range of the distance between the second joint and the third joint in the patient's finger.
If the grip swings within the distance between the second and third joints of the patient's fingers, the forearm and upper arm are pulled when swinging the patient's hand holding the grip. There is no such thing.

The grip portion may be provided with an insertion portion having an arcuate surface at the tip portion. Since the patient can insert the insertion portion of the handle portion into the spastic hand by sliding it, the grip portion can be held with a small resistance.

The grip portion can be gradually thickened from the tip end side toward the base end portion side. When the patient inserts into the insertion part from the side of the first and second fingers of the cramped hand and the patient slides along the grip part, the position where the second and third fingers grip is the fourth finger and It can be opened wide compared to the position where the fifth finger is gripped.

The grip portion may be provided with a grip through which the grip portion is rotatably inserted. By swinging the grip portion, it is possible to prevent the patient's hand from rubbing against the grip portion and damaging the skin.

It is possible to provide a base portion on which the drive portion is installed and arranged at the installation location, and a cover portion for accommodating the drive portion inside by covering the base portion.
By installing the base on the floor or desk as the installation location, the patient can train with both hands free.

The device body may include a device body in which the drive unit is housed, and the device body may include a handle portion held by a healthy hand of the patient and a head provided at the tip of the handle portion. .. Training can be performed while the patient holds the handle with a healthy hand and changes the orientation of the grip held by the spastic hand, or moves the grip in a direction that opens the patient's grip.

The drive unit can swing the grip portion along a virtual fan-shaped plane. If the position where the grip portion is gripped is slid toward the tip portion side, the swing width of the grip portion becomes large. Therefore, by sliding the finger that has begun to open toward the tip end side, it is possible to perform training to smoothly open the finger widely.

The drive unit can swing the grip portion along a virtual rectangular plane. When the grip portion moves in parallel along the virtual rectangular plane, the grip portion moves in a direction in which each finger of the patient is evenly touched and opened, so that each finger can be opened evenly.

The rehabilitation support device of the present invention allows the fingers to be opened without pulling the forearm or upper arm when the hand of the patient holding the grip is swung, so that the rehabilitation support device for a patient with constricted hands can be rehabilitated. It is possible for the patient to do it efficiently without relying on the practitioner.

Can be opened.

If the position where the grip portion 21 is gripped is slid toward the insertion portion 22 by slightly separating the four fingers from the thumb, the swing width of the grip portion 21 becomes large, so that the fourth finger (ring finger) and the fifth finger Even the second finger (index finger) and the third finger (middle finger), which have a larger bending force than the (pinkie), can be smoothly opened wide.

In this way, in the hand of the patient who grips the grip portion 21, the grip portion 21 is swung by the drive unit 30, so that the fingers of the gripped hand are ordered in order without pulling the forearm or upper arm. Can be opened.
In particular, when the drive unit 30 swings the grip portion 21 at the maximum distance between the second joint and the third joint of the patient's finger, the patient's hand holding the grip portion 21 swings. The grip portion 21 can be reciprocated within a range in which the fingers can be opened without pulling the forearm or upper arm.
Therefore, when the patient installs the rehabilitation support device 10 and performs rehabilitation, it is possible for the patient to efficiently perform rehabilitation for the patient with spastic hands without relying on the practitioner.

In addition, the rehabilitation support device 10 allows the patient to perform training with both hands free by installing the base portion 41 on the floor, desk, or the like as an installation location.
