What is the normal range of flexion for the glenohumeral joint?

The normal range of flexion for the glenohumeral joint is indeed around 180 degrees. This is significant because the glenohumeral joint, which is the main shoulder joint, allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation.

During flexion, the humerus moves forward in front of the body, which is crucial for many daily activities such as reaching, lifting, and throwing. A range of up to 180 degrees indicates optimal functional movement, where the arm can be raised forward significantly above the head in a correct and healthy motion.

Understanding the typical range of motion is essential for recognizing limitations or dysfunction in the shoulder joint, which may indicate potential injury or pathology. By knowing that flexion typically reaches up to 180 degrees, practitioners can better assess and formulate rehabilitation strategies for individuals with shoulder conditions.
