What is the normal range of shoulder flexion?

The normal range of shoulder flexion typically falls between 170 to 180 degrees. This range indicates the ability of the shoulder to move forward and upward from the anatomical position. Flexion is an essential movement that allows activities such as reaching overhead, throwing, and many functional tasks in daily life.

Choosing this range reflects an understanding of the anatomical capabilities of the shoulder joint, particularly how the surrounding muscles and structures facilitate this extensive movement. Confirmation of this range can often be found in clinical texts and peer-reviewed studies that describe shoulder anatomy and functional assessment, underscoring the importance of recognizing normal versus limited flexibility in the context of athletic training and rehabilitation.
