How many degrees should the shoulder joint not abduct when posing?

When each joint of the shoulder joint moves, there are both individual movements of each joint and coordinated movements between each joint, so that each joint of the shoulder joint forms a complete whole. When any joint is sick, it will affect its overall functional activities. The active motion functions of shoulder joint complex include abduction, adduction, flexion, extension, abduction and flexion, abduction and extension, abduction and rotation, neutral rotation and rotation, and its active motion (sports food) range is as follows.

Abduction: the upper arm is lifted outward away from the body, and the normal range is 0- 180 degrees.

Adduction: The upper arm moves forward through the body to the opposite limb, and the normal range is 0-45 degrees.

Forward flexion: the upper arm is raised in front of the body, and the normal range is 0- 180 degrees.

Backward extension: the upper arm extends to the back of the body and is lifted, and the normal range is 0-60 degrees.

Abduction flexion: the upper arm is 90 degrees abduction, and the horizontal position is close to the opposite limb through the front direction of the body, and the normal range is 0 ~ 135 degrees.

Abduction and extension: the upper arm is 90 degrees abduction, and the horizontal position extends to the back of the body, and the normal range is 0 ~ 30 degrees.
