The scapula plays a crucial role for proper shoulder function, serving as a stable base for rotator cuff activation and as a link in the kinetic chain. Joint, ligament or muscular problems near the scapula can lead to malpositions or to an altered movement pattern. This abnormal situation is called "scapular dyskinesis", which appears to be a non-specific response to a painful condition of the shoulder. The clinical examination of the scapula is crucial for every patient presenting a painful shoulder. Systematic observation and testing enable the practitioner to detect subtle static and dynamic abnormalities. Visual evaluation, objective measurements and corrective manoeuvres can evaluate the role of the "scapular dyskinesis" in the shoulder painful condition. The scapular rehabilitation will address muscular retractions and imbalances and restore a good dynamic stability, starting with analytical work, and evolving into more functional and specific exercises.
