Description

Leg length mismatch compensation device for pedal type fitness equipment

The present invention relates to a device for correcting leg immobility for a pedal-type exercise device, and more particularly, to a rehabilitation exercise device having a pedal used for correcting and treating spinal diseases, a bicycle or an indoor cycle, etc. It relates to a device for correcting leg immobility for pedal-type exercise equipment, which can be expected to correct and treat spinal diseases caused by gait disorders by resolving discomfort in the body and enabling stable pedal movement.

As modern people lack exercise and more people sit and work in the same position for a long time, one of the diseases that occur frequently is low back pain due to disc and shoulder pain caused by excessive movement of shoulders and arms. ) and muscle pain (筋肉痛), etc., especially in the case of office workers or students who sit for a long time, the number of cases suffering from spinal diseases is rapidly increasing.

On the other hand, the spine is composed of a vertebral body, which is the central body, a bow-shaped vertebral arch protruding from the back upwards, and several projections.孔) is formed, and the spine is maintained in an incorrect posture for a long time, or spinal diseases occur due to muscle aging and strong external shocks. The cause can be found in lifestyle habits such as sitting, standing, or sleeping posture, and in the case of children and adolescents in the growing stage, when there is an abnormality in the spine, the growth line is put under pressure and the secretion of growth hormone is not smooth. Failure to do so may lead to problems that inhibit growth promotion.

As a method to treat these spinal diseases, physical therapy to strengthen muscles, acupressure therapy to ensure smooth blood circulation by stimulating acupuncture points, or acupressure therapy to widen the gap between the narrowed vertebrae and relax the pressed disc by relaxation action. Traction therapy to correct the body shape.

On the other hand, acupressure or massage is a type of manual procedure that corrects the body's alteration to treat diseases and promote health by directly giving mechanical stimulation to the skin in a certain way using hands.手技施術), promotes blood and lymph circulation and metabolism by acupressure massage, increases tissue nutrition, excretes waste, and strengthens resistance. This tactile stimulation (觸壓刺戟) stimulates nerves and acts as an analgesic, so 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 the treatment alone, there is a problem that the effect is not constant because it is carried out depending on the power of the person as well as the inconvenience of receiving the type of help.

In order to improve this, various types of acupressure massagers have been developed and used in the past that can receive acupressure massage on their own. In the case of a massager, as it repeatedly hits (tapping) a part of the body, the acupressure effect is low, and there is a disadvantage of causing secondary pain due to the blow. Since it has to be pressed with a certain force on the part, it is not only inconvenient to use, but also has a problem that it is difficult to use continuously because of the force.

In addition, in the case of a pneumatic massager, the pressure is repeatedly applied to a part of the body by injecting and discharging air into and out of the cuff intended to cover body parts such as arms, legs, or waist. It is difficult to expect acupressure effect such as stimulating acupuncture points, but also has the disadvantage of being cumbersome to use because it has to be worn on the arm, leg, or waist of the body. There is a treatment device equipped with a belt-type cuff that is provided to expand and apply traction, but it is also inconvenient to use because it has to be worn on the neck or waist, and it is difficult to quickly respond to excessive pneumatic action, and sufficient traction effect can be obtained. There was a problem that the treatment effect was low as there was no treatment.

That is, the most ideal treatment and correction method to prevent spinal diseases is to properly correct the body type by the natural healing power according to the relaxation action of the muscles and skeleton by regularly performing stretching exercises to stretch and stretch the whole body.

However, in the pedal-type exercise device according to the prior art, the user puts left and right feet on each pedal disposed on the left and right for pedaling and performs a pedaling operation. In the case of those who had it, there was a problem that the pedaling operation was impossible.

In other words, the difference in the length of the left and right legs is called lower extremity immobility, which means that one leg is longer or shorter than the other. It is not uncommon for such an immobility of the lower extremity to occur temporarily during the growth phase, but if the difference in length is more than 2 cm, there may be clinical problems. If immobility occurs and the difference in length between the left and right legs is more than 2 cm, the short heel of the leg can be raised, surgery to prevent the growth plate of the normal leg from growing when bone growth is complete, or lower extremity extension surgery can be performed. .

This immobility of the lower extremities not only causes discomfort in walking, but also causes various spinal diseases such as compensatory scoliosis, in which the spine is twisted when the pelvis is twisted when standing or walking, as well as hip stiffness.

Therefore, in the case of such a patient with lower extremity immobility, exercise for the entire muscle around the pelvis, spine, and spine is required through rehabilitation above all else, but in the case of the pedal-type exercise device according to the prior art, due to the difference in the length of the left and right legs, There was a problem that it was difficult to use.
