(15, 37) And, it has been demonstrated that patients with slouched
scapulothoracic postures have decreased shoulder abduction ROM and posterior scapular tilting as well as decreased muscle force in glenohumeral abduction above 90[degrees].
Moreover,
scapulothoracic stability plays an important role in the process of transmitting the force from the lower limb and trunk to the upper limb during oscillation (Kibler and McMullen, 2003; Matias and Pascoal, 2006).
Scapulothoracic arthrodesis has been described as the method of treatment for those cases [17].
(19) and the increased stabilization of the
scapulothoracic muscles when using rotational load.
Cervical and
scapulothoracic stabilization exercises with and without connective tissue massage for chronic mechanical neck pain: A prospective, randomised controlled trial.
Scapulothoracic and glenohumeral kinematics following an external rotation fatigue protocol.
[1,2,3,4] Arthrodesis is irreversible, relies on
scapulothoracic motion and permits only a limited range of abduction and includes a high incidence of complications, e.g., fractures [1,2] and pseudoarthrosis.

Electromyographic activity in the immobilized shoulder girdle musculature during
scapulothoracic exercises.
At a larger angle, shoulder abduction occurs at a 2:1 ratio between the glenohumeral joint through abduction of the humerus and the
scapulothoracic joint by lateral rotation of the scapula.
