Pitch represents the head-up and head-down movements, and the main muscles used are longus colli, longus capitis, infrahyoids, splenius capitis, seminispinalis capitis, suboccipitals, and the trapezius muscles. Yaw represents the movement of turning the head to the left or to the right, and the main muscles used are the levator scapula and suboccipitals. Roll represents the movement of tilting the head to one side so that the ear on that side gets closer to the shoulder on that side, and the main muscles used are the scalene muscles [39].
