Fig. 1: The index is placed onto the distal end of the clavicle, the mid-finger onto the acromion. Moving the shoulder allows easily to monitor the movements of the two bones. (Fig. 3 serves as a reference for fig. 1)
Fig. 2: Placing the fingers onto the spina of scapula.
Fig. 4: Identifying the lower angel of the scapula.
