Q

What do closed kinetic chain exercises do?

A

They facilitate co-contraction, permit stabilization with less shear force, facilitate proprioception for stabilization

Q

What is secondary impingement?

A

Subacromial space narrowed by alterations in shoulder function. May be caused by or result in instability.

Q

What is the function of the Serratus Anterior?

A

Holds scapula on wall (protraction)

16
Q

What is the function of the rhomboids and middle trapezius?

A

Prevent round shoulders- control scapular retraction

17
