Additionally, investigations incorporating three-dimensional modeling are needed to directly assess scapulothoracic
and glenohumeral angular positions on the subacromial space.
7) Motion at the clavicle assists in maintaining scapulothoracic
movement and functionality of the shoulder.
motion in normal shoulders and shoulders with glenohumeral instability and impingement syndrome.
Care was taken to ensure minimal to no motion occurred at the scapulothoracic
When the hand is back on the barre it may cause the elbow to be behind the body, which then destabilizes the scapulothoracic
area of the back [the shoulder blade wings off the rib cage]," says Molnar.
For example, overhead throwing can irritate and inflame gliding surfaces between the shoulder blade (scapula) and chest wall--a common problem called scapulothoracic
bursitis, explains Michael S.
The shoulder complex comprises the glenohumeral, acromiaclavicular, sternoclavicular, scapulothoracic
joints and the subacromial space.
They cover anatomy and approaches; glenohumeral instability; rotator cuff and biceps; sternoclavicular joint and clavicle fractures; humeral and scapular fractures; glenhumeral arthritis; muscle ruptures, scapulothoracic
articulation, and nerve problems; elbow trauma; and elbow stiffness.
The prescription of the EC or FC as a strengthening exercise will therefore activate all the rotator cuff and many scapulothoracic
muscles to a significant proportion of their maximal voluntary contraction and will most likely result in similar strength adaptations to all these muscle groups.
arthrodesis: indications, technique and results.
Whilst the glenohumeral, acromioclavicular and sternoclavicular joints were included for treatment in the intervention group, I note that the scapulothoracic
component was not included.
Overuse, trauma of the tendons, anatomic variations of the acromion or coracoid process may lead to narrowing of the subacromial space, while glenohumeral or scapulothoracic
joint instability, faulty posture or posterior capsule tightness may result in impingement due to "relative narrowing" (1,7).
