Q

Rhomboids Minor and Major: Functional Movement?

A

Scapula retraction (pulling shoulders back)

24
Q

Rhomboids Minor and Major: Resisting the muscle?

A

Stand behind the patient.
Place hands on their shoulders and ask them to pull their shoulder blades together against resistance. Apply gentle pressure to resist the squeezing movement.

25
Q

Serratus Anterior: Origin?

Protraction of scapula (reaching forward)

30
Q

Serratus Anterior: Resisting the muscle?

A

Stand beside the patient. Place one hand on the side of their scapula and ask them to reach forward against your resistance. Apply gentle pressure to resist the forward movement.
