Deltoid & Integrated Function| Biomechanics & Pathomechanics [Part 3]

Detailed discussion on deltoid muscle and the role of deltoid in integrated function of shoulder complex. Deltoid is made of three fibers namely: anterior,middle and posterior fibers.Each of these fibers has a specific role and deltoid muscle as a whole is a primer mover of arm in elevation. The anterior fibers regulates flexion, anterior and middle regulate flexion in scapular plane and middle fibers regulate abduction.But its posterior fiber dont have a specific role in elevation and instead act as a joint compressor.
Watch video to know the peak power of deltoid action , the role of serratus anterior and trapezius in deltoid function. Also get to know how the rotator cuff muscles influences deltiod function.
