Which reference point do you palpate to check for protraction of the scapula?

To assess for protraction of the scapula, palpating the acromion process is key. The acromion process is the bony prominence at the top of the shoulder, where the scapula (shoulder blade) connects with the clavicle (collarbone). When the scapula is in a protracted position, it moves away from the spine and the acromion can appear more prominent or may feel displaced compared to its normal alignment.

By focusing on the acromion process, you can gauge the extent to which the scapula has moved forward. A normal positioning of the scapula should show the acromion in a more retracted position, resting close to the thoracic spine. Therefore, any significant movement of the acromion forward indicates protraction, allowing for an effective assessment of scapular positioning relative to the spine.

The other reference points, while they serve important roles in the overall analysis of shoulder and upper back mechanics, do not provide the same direct indication of scapular protraction as the acromion process.
