Anterior Tilt is caused by
- A.
Glenohumeral Hyperextension
- B.
Glenohumeral Hyperflexion
Correct Answer
A. Glenohumeral HyperextensionExplanation
Anterior tilt refers to the forward rotation of the pelvis, causing an increased curvature in the lower back. Glenohumeral hyperextension is the correct cause of anterior tilt. This means that the shoulder joint is excessively extended or pushed backward, which can lead to compensatory changes in the pelvic alignment. Glenohumeral hyperflexion, on the other hand, refers to excessive flexion or forward movement of the shoulder joint, which would not directly contribute to anterior tilt. Therefore, the correct answer is Glenohumeral Hyperextension.Rate this question:

Posterior Tilt is caused by
- A.
Glenohumeral Hyperextension
- B.
Glenohumeral Hyperflexion
Correct Answer
B. Glenohumeral HyperflexionExplanation
Posterior tilt refers to the backward rotation of the pelvis, causing the top of the pelvis to tilt backward. Glenohumeral hyperflexion is the excessive flexion or forward movement of the shoulder joint. The correct answer, Glenohumeral hyperflexion, suggests that excessive flexion or forward movement of the shoulder joint can cause posterior tilt. This means that when the shoulder joint is flexed too much, it can lead to a backward rotation of the pelvis, resulting in posterior tilt.Rate this question:
