Sitting, standing, or lying supine
Anterior or lateral to the patient.
Please sit down. May I touch the side of your neck and your head? (or point to the area). Please hold while I try to push your head to the side.
Guide the patient to sit down. Place your fingers on the sternocleidomastoid muscle for orientation. With the patient relaxed and with permission, place your fingers on the scalene muscles, just posterior to the sternocleidomastoid muscle. Ask the patient to hold while you push on the side of the skull to resist ipsilateral lateral flexion.
