Pectoralis minor and thoracic outlet

This short video shows Pectoralis minor and thoracic outlet in the context of “Thoracic outlet syndrome (TOS).” Hypertonus or imbalance in the trapezius muscle and improper posture contribute to tension throughout the area, which indirectly results in compression between clavicle and first rib. This area is particularly vulnerable to trauma or excessive overhead. It also shows the areas where pain, burning or tingling may travel when a nerve structure is irritated or sensitive to movement.

What can you see in the clip?

Hypertonus or imbalance in the trapezius muscle and improper posture contribute to tension throughout the area, which indirectly results in compression between clavicle and first rib. This area is particularly vulnerable to trauma or excessive overhead. The clip places this within “Thoracic outlet syndrome (TOS)” so it is easier to understand what is happening in the area, not only where symptoms are felt.

How does this relate to symptoms?

Nerve-related symptoms are not always felt where the irritation begins. The visual shows a possible symptom pathway, while movement, strength and sensitivity still need to be assessed in the individual person.

How should you use this information?

This is an educational visual linked to “Thoracic outlet syndrome (TOS).” If symptoms keep returning, restrict movement, or their source is unclear, a functional assessment is a more useful next step than guessing.
