Superior Oblique Action

The superior oblique runs through a trochlea or “pully” that effectively changes the functional origin of the muscle. To simulate the action of the superior oblique muscle, you can pretend that your head is a giant eyeball. Simply wrap your hand behind your head and pull. The direction of eye movement changes depending upon which direction you look. When the eye (your head) is turned nasally (toward your elbow) you get more up-down movement. When the eye is turned outwards, the muscle creates more of a side-to-side rotational action.
