Place one hand over the navel and with the fingers of the other hand press and/or massage the 'balance buttons' which are located just above the indentation where the skull rests over the neck, about one and one-half to two inches to each side of the back midline, and just behind the mastoid area. Usually a person changes hands to more easily reach each side. Keep the chin tucked in and keep the head level. Once comfortable with the basic movement, try pressing the head back against the fingers.
Rationale: Stimulates the vestibular system and the oculomotor system. Also stimulates reticular activating system. Lessens neck and jaw tension.
