What should be compared to assess scapular alignment from the back view?

To assess scapular alignment from the back view, comparing the width of the scapula to the spinous processes of the vertebrae is crucial. This relationship helps determine whether the scapulae are positioned symmetrically and properly relative to the spine. Ideally, the scapulae should maintain an appropriate distance from the spinous processes, demonstrating proper alignment and optimal postural mechanics.

This assessment can help identify issues such as winging or scapular dyskinesis, where the scapula may not move correctly or is positioned incorrectly. By focusing on the scapular width in relation to the spinous processes, practitioners can better understand potential imbalances or misalignments in the shoulder girdle, which may contribute to upper back and shoulder problems.

While the width of the shoulders, the height of the humeri, and the position of the neck may provide valuable information about overall posture, they do not offer as direct or specific an insight into scapular alignment as the comparison with the spinous processes does. This comparison emphasizes the relationship between the shoulder girdle and the spine, which is critical for assessing and addressing postural issues effectively.
