Chin Nodding in Supine

The patient is lying on their back and places one hand under the upper part of the neck, at the base of the skull.
Ask the patient to attempt to nod the chin down slightly, increasing the pressure against the hand under the upper neck. Instruct the patient to avoid pushing their head back toward the table.
There should not be any palpable tension in the superficial muscles in the front of the neck as they perform the exercise.
The patient is instructed to hold for 10 seconds and repeat 3-5 times, gradually working up to 10 repetitions.
