Technical Tuesday
Supraspinatus
Supraspinatus. Now there’s
a great word. You might think that a mouthful like that would correspond to a
great big muscle. But no. The supraspinatus is actually a small muscle, located
beneath the acromium (top part of the scapula).
The supraspinatus is a
rotator cuff muscle, and, along with the deltoid and pectoralis major muscles, it
assists in raising the arm upwards (horizontal abduction), and also helps
stabilize the shoulder.
The supraspinatus can be
susceptible to overuse injuries, especially when the arms are at or above
shoulder level. Think Swan Lake, or even
just fifth en haut. But fortunately, the supraspinatus is not commonly injured
in dancers. Instead, it is injuried more often in sports, especially if throwing a
ball is involved. Dancers aren’t likely to use their arms with that much force!
From the Big Blue Book of Ballet Secrets:
Dance History Factoid # 94
“The
supraspinatus is a small muscle that does big things.”
