Abstract

The shoulder refers to the area connecting the human torso and arms, and plays a key role in moving both arms. In particular, it plays the most important role in sending both hands behind the head or away from our bodies. In this paper, we measure the angles of the medial and lateral rotations of the arm from the shoulder, identify the symptoms associated with abnormalities, and propose ways to prevent these symptoms. The angle of medial rotation and lateral rotation of the upper limb in the shoulder is generally 70° ~ 90°. If the angle falls below the reference value or feels pain, something is wrong with the shoulder. In addition, a total of 100 people (50 men and 50 women each) were tested to determine patients with abnormalities.

어깨는 인간의 몸통과 양팔을 연결하는 부위를 말하며, 양팔을 움직이는데 핵심적인 역할을 한다. 특히 양손을 머리의 뒤쪽으로 보내거나 우리 몸으로부터 멀리 보내는데 가장 중요한 역할을 수행한다. 본 논문에서는 어깨에서 팔의 안쪽 돌림과 가쪽 돌림에 대하여 각도를 측정하고, 이상 유무와 관련된 증상을 파악하며, 이러한 증상을 예방하는 방법까지 제시하도록 한다. 어깨에서 팔의 안쪽돌림과 가쪽 돌림의 각도는 70°~90°가 일반적이다. 그리고 각도가 이에 못 미치거나 통증을 느끼면 어깨에 이상이 생긴 것이다. 또한 일반인 남녀 각각 50명씩 총 100명을 대상으로 실험을 수행하여 이상이 있는 환자를 판별하였다.
