Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rehabilitation exercise apparatus,

The present invention relates to a rehabilitation exercise apparatus for both upper and lower limbs, and more particularly, to a rehabilitation exercise apparatus for both upper and lower limbs, and more particularly, to a limb To a rehabilitation exercise device for rehabilitation therapy in a safe manner.

In general, hemiplegia can occur due to movement disorders and sensory deficits due to central nervous system injuries such as stroke, traumatic brain injury, or cerebral palsy, imbalance in posture, lack of physical self-awareness, It is one of the exercise paralysis that can not use the muscles of the right size to generate appropriate strength at the required moment.

Hemiplegia is a state in which the muscles of the upper and lower limbs of the right or left side are lowered together and can not move. In general, hemiplegia is called hemiplegia. Hemiplegia is caused by a disability in the cortex, the cortex, the cortex, the inner capsule, and the brainstem, which control the veterinary movement (arbitrary movement). Then, And most of the spinal cord at the border crossing, paralysis occurs on the other side of the disorder. In general, hemiplegia is caused by cerebral vascular disorder, ie, stroke. In addition, it may be caused by brain tumor, multiple sclerosis, head trauma, brain abscess.

In order to rehabilitate upper limb patients with hemiplegia due to stroke, physiotherapists generally have to perform passive exercise therapy, which requires a significant amount of effort by the therapist.

The most important aspect of hemiplegic treatment is symmetrical movement, and an important factor of this symmetrical movement is weight bearing. It is widely used for hemiplegia treatment. It includes flexion flexing with the joints of the elbows, wrists, and knees as an axis, extensions extending in the opposite direction, inwardly rotating the upper limbs or the lower limbs pronation), as well as supination, which rotates outward. The sick side of a hemiplegic patient is called the affected side, and the uninvolved side of the patient is called the unaffected side. In the case of hemiplegia, the side of the bulb becomes deformed and becomes worse with time. Hemiplegia patients compensate for the need to help the affected side of the brain to work on the affected side to compensate for the movement occurs during a long time to change. In order to treat hemiplegia, various rehabilitation devices have been developed, but most of them are upper extremity rehabilitation treatment devices. In addition, the range of exercise and the speed of exercise are very important for exercise therapy of hemiplegic patients. Currently, it is dependent on manual therapy of physical therapist, and it is almost impossible to control accurately according to exercise therapy of hemiplegic patients .

Therefore, it is urgent to develop a hemiplegic upper limb rehabilitation treatment device which can adjust the range of motion and the speed of motion according to the will of the hemiplegic patient's own will.

In addition, conventional upper extremity rehabilitation devices of hemiplegic patients only deal with shoulders or elbows, and there is almost nothing about wrists. Therefore, the development of upper limb rehabilitation apparatus that can treat not only the forearm but also the wrist is also an urgent need Do.

The upper limb rehabilitation devices of the prior art have a disadvantage of consuming external power by themselves because the upper limb rehabilitation devices of the present invention have a secondary motion transmission mode in which the force on the unilateral side is converted into an electrical signal and transmitted to the affected side in symmetric motion, The rehabilitation devices had the disadvantage of the machine movement that one person could not move the apparatus because the volume of the machine was too large.

Accordingly, conventional upper-limb rehabilitation devices such as Korean Patent No. 1099063, which perform a mirror action, are bulky, heavy, use an external power supply, and are not multi-functional It has disadvantages.

SUMMARY OF THE INVENTION The object of the present invention is to provide stability in the upper and lower limb rehabilitation exercise of the hemiplegic patient and to induce the superior and inferior limb movement near the normal by inducing the valgus / (Motion) of the affected side (hand) or the affected side (ankle) by activating the stimulation of the brain to perceive the normal movement of the affected side hand or leg to the patient's brain.

In order to achieve the above object, according to the present invention, there is provided a gear shift mechanism comprising: a first toothed gear that rotates by transmitting power by a first drive motor to move an arm or a leg; A first driving part composed of a semicircular first support part with one side of the second toothed gear and the second toothed gear engaged and an upper part opened so that an arm or a leg is seated,
