Interrater reliability of clinical tests to evaluate scapulothoracic motion.
Scapular movement plays a key role in shoulder and arm function. The scapula acts as a stable base for optimal muscle activation and as a transfer link for developed forces in the kinetic chain. Shoulder pain and several pathologies, such as shoulder impingement, rotator cuff tendinopathy, rotator cuff tears, glenohumeral instability, adhesive capsulitis and stiff shoulders, are associated with alteration in scapular kinematics. Therefore, the evaluation of scapular kinematics should form a part of clinical shoulder joint examination.
The aim of this study was to evaluate the interrater reliability of four clinical tests to assess scapulothoracic motion in patients with a slightly restricted shoulder flexion.
Our study demonstrates that the four mobility tests of the shoulder [A&P: see image and free full text article below] are a reliable and simple instrument in the assessment of patients with a slightly restricted shoulder flexion. Nevertheless, validity has to be investigated before the clinical utilisation of these tests can be approved, e.g. comparing the four mobility tests of the shoulder with electromagnetic kinematic testing. Moreover, further studies are needed to show correlations between restricted scapular motion and shoulder pathologies. Additionally, the effect of specific treatment of patients with restricted scapular motion would be of great interest > from Baertschi et al., BMC Musculoskeletal Disorders (2013) 14:315.
