Left side-bending is introduced through the operator’s right forearm by slight left-to-right translation. (Rotation is not actively introduced)OAflex5



The patient is instructed to look down at the feet or pull the chin toward the chest against resistance offered by the operator’s right hand for a 3-5 second light isometric muscle contraction.
