Description

{Postural Balance Training Machine}

The present invention relates to a posture balance training apparatus, and more particularly to a posture balance training apparatus capable of simultaneously performing posture balance training by voluntary center-of-gravity movement and posture balance training by external disturbance.

With the improvement of living standards and the development of medical technology, the number of elderly people over 65 is increasing. Elderly people suffer from aging or disease and their postural balance ability is lowered, and this decrease in postural balance ability leads to falls. Falling prevents activity for a long period of time, resulting in weakening of secondary strength, contracture and weakening of bone mineral density, and weakening of physical function causes fall again. If this vicious cycle persists, it will eventually lead to death due to infectious diseases such as pneumonia, so maintaining postural balance ability is a very important factor for quality of life and social activities.

In addition, the increase in the fall population causes the deterioration of the national health insurance finances and raises the social cost.

Therefore, it is essential to improve postural balance ability for elderly people and patients with various diseases. For this reason, many postural balance training devices have been recently developed more and more.

Among them, the postural balance training apparatus (application number: 10-2007-0049413, patent holder: Chonbuk National University Industry-Academy Collaboration Team), which was filed on May 21, 2007, is designed to allow the user to voluntarily balance his / There is a problem that training means are not provided. This technique can be applied to disturbance, and the angle of the foot plate is adjusted in the front and rear left and right directions, and the angle is adjusted in the front and rear left and right directions. However, since there is no load cell and the center of gravity of the user can not be grasped, There is a problem.

The electronic postural balance diagnosis system (Application No. 10-2000-0053388, patentee: HumanTech), which was filed on September 08, 2000, has two or more load cells mounted symmetrically on the foot plate to measure the body weight, It is possible to measure the degree of balance of the body and the balance of the left and right by grasping the degree of bias toward the left and right symmetry, but there is a problem that the balance of the body can not be measured.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems of the conventional art described above, and it is an object of the present invention to provide a training apparatus and a training apparatus which are capable of performing a training in which a user can move a center of gravity of a self- The object of the present invention is to provide a postural balance training device capable of simultaneously performing a training for balancing the posture.

In addition, the foot plate can be adjusted in the left-right direction and the back-and-forth direction, and a plurality of load cells can be installed symmetrically in the front, rear, left and right directions to grasp where the center of gravity of the user is, And to provide a postural balance training device that can efficiently perform supplemental training on balance.

If the power is not supplied to the first electric motor of the front and rear tilting units and the second electric motor of the left and right tilting units, the user moves the center of gravity spontaneously while standing on the foot plate, There is an advantage to training for catching.

In addition, when power is supplied to the first electric motor of the front tilting portion and the second electric motor of the left and right tilting portion, the foot plate is suddenly inclined in a specific direction, and the unexpected inclination of such foot plate causes sudden disturbance And thus it is possible to efficiently perform the posture balance training to cope with a similar real situation in which falls can be generated. Conventional postural balance training apparatuses provide a simple repetitive motion trajectory so that the user can predict in advance and thus the abrupt situation provides many difficulties in coping with a real situation. However, according to the present invention, There is an advantage to be able to cope efficiently with unpredictable reality situations.

In addition, by providing a plurality of load cells on the foot plate so as to be symmetrical in the longitudinal, lateral, and lateral directions, the user can easily grasp where his / her own weight is located and can easily grasp in which direction the balance of the human body is biased .
