Cinesiology of the Shoulder Girdle

A glenohumeral joint has the biggest motility from all the joints in the body. Even so other joints significantly take part in the movements of the shoulder girdle (see false articulations and right articulations sharing the construction of the shoulder girdle). Without any co-ordination of the movement of the glenohumeral articulation with these joints the full movement of the shoulder girdle is not possible. In most cases the meaning of motility of the glenohumeral articulation is overestimated, and the activity of remaining parts is underestimated. Even so during an examination of movements we can differ if it rather deals with an isolated affection of the glenohumeral articulation or a complex affection of all the parts of the shoulder girdle. A differentiation is possible to be carried out at the examination of complex movements or isolated movement.

Complex movements of the shoulder girdle are movements of the whole girdle during which all its parts are involved.

General features of complex movements

 

Isolated movements are movements bound only to the glenohumeral articulation (not the whole shoulder girdle!!!) and to structures connected with it.
