An attachment Trp (ATrP) at the lower end of the Sternal Division may refer pain downward over the upper portion of the Sternum
- This is the only downward reference of pain from this muscle
- True Trigeminal Facial Neuralgia is not accompanied by sternal pain, which, when also present, suggests the Sternocledomastoid Myofascial Syndrome
- When this ATrP is present in the lowest part of the Sternal Division, those fibers may merge with a slip of the inconstant Sternalis
- Occasionally, mechanical stimulation of this sensitive area may be associated with a paroxysmal dry cough
Sternocleidomastoid “Amazingly Complex”
Sternal Division Lower Attachment TrPs
At the midlevel of the Sternal Division, TrPs refer pain homolaterally, arching across the cheek (often in finger-like projections) and into the Maxilla, over the Supraorrbital Ridge and deep within the Orbit
-The TrPs along the inner margin at the midlevel of this division refer pain to the Pharynx and to the back of the tongue during swallowing (which causes “sore throat”) and to a small round area at the tip of the chin, including the cheek, Temporomandibular joint and Mastoid areas
Sternocleidomastoid “Amazingly Complex”
Sternal Division Midlevel TrPs
The TrPs located toward the upper end of the Sternal Division are more likely to refer pain to the Occipital Ridge behind, but not close to the ear, and to the vertex of the head like a skull cap, with scalp tenderness in the pain reference zone
Sternocleidomastoid “Amazingly Complex”
Sternal Division Upper Attachment TrPs
Autonomic concomitants of TrPs in the Sternal Division relate to the homolateral eye and nose
- Eye symptoms include excessive lacrimation, reddening (vascular engorgement) of the conjunctiva,, apparent “ptosis” (narrowing of the palpebral fissure) with normal pupillary size and reactions, and visual disturbances
- -The “ptosis is due to spasm of the Orbicularis Oculi muscle, rather than to weakness of the Levator Palpebrae muscle. The spasm is apparently caused by referred increased excitability of the motor units of this muscle

Sternal Division Concomitants
The client may have to tilt the head backward to look up, because of inability to raise the upper eyelid
- Visual disturbances can include not only blurring of vision, but also dimming of perceived light intensity
- Sometimes coryza and maxillary sinus congestion develop on the affected side

Sternal Division Concomitants
Unilateral deafness with no complaint of tinnitus has been traced to TrPs in the Sternocleidomastoid
- Tinnitus may be attributed to TrPs in either the Sternocleidomastoid, Upper Trapezius, or Cervical Paraspinal muscles
- Unilateral tinnitus may be associated with a TrP in the Deep Division of the Masseter muscle
- Tinnitus is usually associated with the deep part of the Masseter rather than the Sternocledomastoid
- A crackling sound in the homolateral ear may occur and can be reproduced by pinching the superficial fibers of the Sternal Division at its midlevel

Sternal Division Concomitants
Myofascial TrPs in the midfiber part of this division refer pain to the frontal area and when severe, the pain extends across the forehead to the other side (cross reference), which is very unusual for TrPs
Sternocleidomastoid “Amazingly Complex”
Clavicular Division Midlevel Attachment TrPs
The upper part of this division is likely to refer pain homolaterally deep into the ear and to the posterior auricular region
-These TrPs sometimes refer poorly localized pain to the cheek and molar teeth on the same side
Sternocleidomastoid “Amazingly Complex”
Clavicular Division Upper Attachment TrP
Proprioceptive concomitants of TrPs in the Clavicular Division relate chiefly to spatial disorientation
- Clients complain of postural dizziness (in the form of a disagreeable movement or sensation within the head), and less often, of Vertigo (the sensation of objects spinning around the client, or of the client spinning
- During severe attacks, Syncope following sudden turning of the head may be due to stretch-stimulation of active TrPs in the Clavicular Division
Sternocleidomastoid “Amazingly Complex”
Clavicular Division Concomitants
Episodes of dizziness lasting from seconds to hours are induced by a change of position that requires contraction of the Sternocleidomastoid muscle, or that places it on a sudden stretch
- Disequilibrium may occur separately from, or be associated with postural dizziness and may cause sudden falls when bending or stooping, or Ataxia (unintentional veering to one side when walking with the eyes open)
- The client is unable to relate the Vertigo or dizziness to a particular side of the head, even though it can be shown to depend on trigger mechanisms in only one Sternocleidomastoid muscle
