To further classify spasmodic torticollis, one can note the position of the head. Torticollis is the horizontal turning (rotational collis) of the head, and uses the ipsilateral splenius, and contralateral sternocleidomastoid muscles. This is the "chin-to-shoulder" version. Laterocollis is the tilting of the head from side to side.
Rhythmic movement disorder (RMD) is a neurological disorder characterized by repetitive movements of large muscle groups immediately before and during sleep often involving the head and neck. It was independently described first in 1905 by Zappert as jactatio capitis nocturna and by Cruchet as rhythmie du sommeil . [ 1 ]
The main job of the sternocleidomastoid muscle is to help move the head and neck by turning the head to one side and bending the neck forward. [25] The sternocleidomastoid muscle gets its blood from different arteries in the neck, which bring oxygen and nutrients to keep the muscle healthy.
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

Bobble-head doll syndrome is a rare neurological movement disorder in which patients, usually children around age 3, begin to bob their head and shoulders forward and back, or sometimes side-to-side, involuntarily, in a manner reminiscent of a bobblehead doll.
In severe forms, the head and upper shoulders may be bent at a right angle relative to the trunk. [7] Festination [1] is a combination of stooped posture, imbalance, and short steps. It leads to a gait that gets progressively faster and faster, often ending in a fall. Gait freezing, also called motor blocks, is a manifestation of akinesia. [1]
Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
Neck creaking or cracking of the neck is a clicking sound caused by movements of the neck. It can be a normal joint cracking or caused by arthrosis. [1] [2] References
