There is a growing body of literature associating abnormal scapular positions and motions,
and, to a lesser degree, clavicular kinematics with a variety of shoulder pathologies. The …

The etiology of rotator cuff tendinopathy is multi-factorial, and has been attributed to both
extrinsic and intrinsic mechanisms. Extrinsic factors that encroach upon the subacromial …

Subacromial impingement syndrome is the most common disorder of the shoulder, resulting
in functional loss and disability in the patients that it affects. This musculoskeletal disorder …

We use the acronym SICK to refer to the findings one sees in this syndrome (Scapular
malposition, Inferior medial border prominence, Coracoid pain and malposition, and …

The scapula serves many roles in order for proper shoulder function to occur. These roles
include providing synchronous scapular rotation during humeral motion, serving as a stable …

Scapular dyskinesis is an alteration in the normal position or motion of the scapula during
coupled scapulohumeral movements. It occurs in a large number of injuries involving the …

Context: Shoulder injuries are common in athletes involved in overhead sports, and
scapular dyskinesis is believed to be one causative factor in these injuries. Many authors …

Study Design This study used a prospective, single-group repeated-measures design to
analyze differences between the electromyographic (EMG) amplitudes produced by …

We compared normalized trapezius muscle activity and intramuscular balance ratios
between overhead athletes with impingement symptoms and non‐injured athletes during …

Shoulder impingement is a common condition presumed to contribute to rotator cuff disease.
Impingement can occur externally with the coracoacromial arch or internally with the glenoid …
