More Information about the Supraspinatus Muscle
The name for the supraspinatus muscle is derived from the Latin words 'supra'
which means above and 'spina' which means spine. The supraspinatus
initiates abduction & dynamic caudal glide while the deltoid acts as the prime
mover during shoulder abduction.
The supraspinatus is the rotator cuff muscle which is most commonly injured. The
inability to smoothly abduct the arm against resistance may demonstrate the
presence of a rotator cuff injury.
