Once you have located the LOCAL muscle correction to be made (local, muscle is active) then use ulnar edge of your hand on that point to locate the vector to the other correction point. Place one digit (presumably your thumb) at the local spot, and slide another digit (presumably a finger) along the muscle fiber, following the vector you found until you get the other hit. These are your two points. Stretch them apart along the vector indicated by your test until the signal clears.

Whew--it's a lot easier to show this than to explain it.

Occasionally, you will need to treat origin and insertion, rather than muscle spindles, and the location of your hits will demonstrate this. Also, occasionally you may need to squeeze, rather than stretch, and your signal will indicate this with challenge. But it's nearly always a stretch.

Hope this helps!
