Description

Spinal muscle exercise equipment for spinal rehabilitation and correction

The present invention relates to a spinal muscle exercise device for spinal rehabilitation and correction, and more particularly, in correcting or treating various spinal diseases caused by deformation and imbalance of muscles around the pelvis and spinal column, which are the main causes of back pain. The lumbar bed supporting the thoracic vertebrae rotates left and right at a predetermined angle while the pelvis is fixed through arm and leg exercises in consideration of biomechanics and kinematics in the lying position and traction is performed at the same time. Regarding spinal muscle exercise equipment for spinal rehabilitation and correction, which induces proper alignment of the pelvis and spine by relaxing and contracting muscles around the spine, thereby relieving back pain through muscle strength improvement and increasing the effect of correction and treatment of spinal diseases will be.

As more and more modern people sit and work in the same posture for long periods of time due to lack of exercise, one of the frequently occurring diseases is back pain caused by discs and shoulder pain caused by excessive movements of the shoulders and arms. ) and muscle pain. In particular, office workers and students who sit for a long time are suffering from spinal diseases.

On the other hand, the spine is composed of parts such as a vertebra that serves as the central body, a bow-shaped vertebral arch protruding from here to the rear and upper, and several projections. cavities) are formed, and spine diseases occur due to maintaining the wrong posture for a long time, muscle aging, or strong external shock. , The cause can be found in living habits such as sitting, standing or sleeping posture, and in the case of children and adolescents in the growing period, if there is an abnormality in the spine, the growth line is put under pressure, and accordingly, the secretion of growth hormone is not smooth. Failure to do so may lead to problems that impede growth promotion. Methods for treating these spinal diseases include physical therapy to strengthen muscles, acupressure therapy to ensure smooth blood circulation by stimulating acupoints, or relaxation by relaxing the intervertebral discs that have been pressed by widening the gap between the narrowed vertebrae. There are traction treatments that correct the body shape.

On the other hand, acupressure or massage (massage) is a kind of manual procedure that corrects the body's modulation by directly giving mechanical stimulation to the skin in a certain way using the hands to cause a bioreaction to treat diseases and improve health (手技施術), acupressure massage promotes circulation of blood or lymph, boosts metabolism, enhances tissue nutrition, excretes waste, and enhances resistance. Since this tactile stimulation stimulates the tactile sense and acts as an analgesic, it promotes the recovery of paralyzed nerves and has the effect of correcting the modulation of internal functions.

However, since most of these acupressure massages cannot be performed by the person receiving treatment alone, there is a problem in that the effect is not constant because it is performed by relying on the power of a person as well as the inconvenience of having to receive type help.

In order to improve this, various types of acupressure massagers that can receive acupressure massage by themselves have been developed and used in the past. In the case of a massager, it is a method of repeatedly hitting (tapping) a part of the body, so it has a disadvantage of not only having a low acupressure effect but also causing secondary pain by hitting. Since the part must be pressed with a certain force, not only the inconvenience in use is great, but also the continuous use is difficult due to the force. In addition, in the case of an air pressure massager, pressure is repeatedly applied to a part of the body by injecting and discharging air into a cuff designed to cover a body part such as an arm, leg or waist of the body, and simply a part of the body Since it is only a massage, it is difficult to expect acupressure effects such as stimulating acupuncture points, and it is cumbersome to use because it must be worn on the arms, legs, or waist of the body. Although there is a treatment device equipped with a belt-type cuff that is inflated and provided with a traction force, it is also inconvenient to use because it must be worn on the neck or waist, and it is difficult to respond quickly in case of excessive pneumatic action, and sufficient traction effect can be obtained. There was a problem that the treatment effect was low according to the absence.

That is, the most ideal treatment and correction method to prevent spinal diseases is to regularly perform stretching exercises that stretch the entire body to correct the body shape by natural healing power resulting from the relaxation of muscles and skeletons. Prior art for this As an example, there is a chiropractic exercise device disclosed in Korean Patent Registration No. 0711104. This chiropractic exercise device is provided with a lower extremity exercise device that allows the user to lie down and exercise the lower extremities, a bed on which the user can lie down, and a pelvic belt that fixes the user's waist.

As another prior art, 'a spinal muscle strengthening exercise device for relieving back pain and correcting the spine' has been proposed through Korean Patent Registration No. 10-1142888, and the user fixes the waist in a lying position using a pelvic belt A technique has been proposed that allows the user to lie on a bed and roll a pedal-type exercise device, thereby repeatedly relaxing and recovering the human spine and strengthening the supporting muscles around the spine to obtain corrective and therapeutic effects. As another prior art, 'rehabilitation exercise equipment for spine correction' has been proposed through Patent Registration No. 10-1272196, and as another prior art, spinal rehabilitation and correction through Patent Publication No. 10-2012-0100613 A spinal muscle exercise device has been proposed.

However, the pedal-type exercise equipment according to the prior art has a complicated structure and is difficult to maintain, and simply expects a corrective action through lower limb exercise and arm exercise in a state in which the lumbar and thoracic vertebrae are fixed, thereby correcting and In order to obtain a therapeutic effect, there was a problem in that satisfaction with the use of the product was reduced due to the disadvantage of having to be repeated for a long time. For example, medical treatment methods such as preservation therapy, nerve anesthesia injection, and surgical treatment such as disc removal, as well as treatment methods such as acupuncture, moxibustion, herbal medicine intake, chiropractic correction, manual massage, and massage or exercise such as Pilates While it is possible to temporarily relieve pain, fundamental treatment is difficult. In particular, surgical treatment such as disc removal has side effects and a high risk of recurrence.

The present invention was created to solve the problems of the prior art as described above, and an object of the present invention is to link the foot exercise using a lower extremity exercise device such as a stepper in a state in which the pelvis and lumbar spine are bound in a lying position by the user The lumbar bed supporting the user's back rotates by a predetermined angle to the left and right, and the lumbar bed is separated from the pelvic bed in conjunction with the arm movement in which the user moves the handle forward and backward, generating a stretching action by traction. It is an object of the present invention to provide a spinal muscle exercise device for spinal rehabilitation and correction that enables effective treatment and correction of various spinal diseases including pelvic distortion.

That is, the object of the present invention is to provide an exercise device that induces proper alignment of the pelvis and spine by relaxing and contracting the muscles around the pelvis and spine through exercise by the user, and relieves back pain by improving muscle strength and rehabilitates the pelvis and spine with a healthy body. to be
