Description

A muscular power and joint pressure measuring device

The present invention relates to an apparatus for measuring muscle strength and joint pressure, and more particularly, measuring muscle strength and joint pressure by connecting the cadaver model of the arm for each muscle to measure the tensile force required for muscle contraction and relaxation and the pressure applied to the inside of the joint It's about the device.

In the West, kinematics was first brought into scientific light in the latter part of the 20th century by the work of Dr. George Goodheart (Goodheart, G., 1976. Applied kinesiology, 12th ed. Detroit: Privately Published.). He discovered for the first time that muscle strength is increased when stimulated by nutrients that are good for the body, while muscle response is significantly weakened when stimulated by substances harmful to the human body. His tests suggested that the muscles of the human body already knew what was good and what was bad, even when little could be known from superficial consciousness. A representative example widely known after this test is artificial sweetener. Artificial sweeteners, without exception, weakened muscles, whereas natural ingredients that are good for the body strengthened them.

In the late 1970s, John Diamond (Diamond, J. 1979. Behabioral Kinesiology. New York: Harper&Row, 1979. Your Body Doesn't Lie. New York: Warner Books) developed 'Kinematics of Behavior' into 'behavioural kinetics'. He discovered the surprising fact that not only physical stimuli but also emotional and intellectual stimuli strengthen or weaken muscles. A smile strengthens your muscles, and saying I hate you weakens them. However, it was difficult to obtain a value that can be objectively reproduced by relieving people's strength as a device for measuring the values for judging these results (Kendall, HO Muscles: Testing and Function, Baltimore: Williams & Willkins, end ed., 1971).

On the other hand, in Oriental and Korean oriental medicine, the method of diagnosing constitution by understanding the strength test has been widely known since ancient times. This test method is to classify the person's constitution into Taeyangin, Taeeumin, Soyangin, and Soeumin by measuring the physical strength of the right arm while holding food such as radish, cucumber, carrot, and potato in the left hand. At this time, as a way to test the strength of the right arm, it was possible to examine the strength by lifting a sandbag or a barbell, or by lifting the ring connected to the scale with the right arm. This method was developed around 1970 by a Japanese doctor, Omura Oshigi, and is also called the 'Omura test'. In this method, with the thumb and index finger of the right hand taken in the form of an O-ring, the examiner conducts a test in which the subject's thumb and forefinger are spread apart to determine the subject's constitution. However, since this test method also relies on human senses, it is difficult to measure quantitative and reproducible values.

In addition, the above-described methods for measuring muscle strength are limited in that only a living person can measure muscle strength only by directly responding to the test, and there is a problem in that the pressure applied to the joint cannot be measured.
