PECTORALIS MINOR

Its Effects on Hand and Neck Function
 

Hidden beneath big brother, pectoralis major. Like Rodney Dangerfield, it gets no respect. But, the little stinker can be the “Hidden Nemesis” in shoulder, arm, hand, neck and even contralateral hip dysfunction. A hypertonic pectoralis minor has Davis’ Law effects on the upper trapezius and levator scapula, among others, thus influencing neck function. It also has neurovascular implications in thoracic outlet syndrome thus influencing hand function. We will emphasize the importance of knowing, understanding and applying the knowledge of the origin-insertion-actions of muscles and the Laws of Physiology. With the power of that information, along with a good case history and postural examination, you can set up an efficient and effective treatment strategy based on sound physiological principles.

By scapular protraction and inferior rotation of the glenoid fossa, a hypertonic pectoralis minor limits full flexion of the arm, which results in decreased motion reaching forward and upward. There will be decreased motion reaching backward with arm at shoulder level. Patient will exhibit weak arm extension due to an inability of pectoralis minor to stabilize the scapula as we’ll see during the muscle test. When there is also subscapularis involvement, there is restriction of arm abduction and lateral rotation at shoulder level.

A hypertonicity (too tight) of this muscle calls into play the need for understanding of two very powerful neuro-phenomenon…Davis’ Law and reciprocal inhibition.

Learn how to apply specific techniques to two nervous system receptors that will allow the scapula to resume its proper position. This proper position will allow the muscles that attach the cervical spine to the scapula to better perform their function of efficient, pain-free movement of the head and neck.

I am looking forward to sharing this knowledge with you!
