This article presents a case study of a patient diagnosed with dysfunction of the sternocleidomastoid (SCM) muscle, a condition which can result in head and face pain, nausea, dizziness, coryza, and lacrimation. In this particular case, the SCM muscle had developed tightness and weakness with presence of multiple trigger points within both heads.

Sternocleidomastoid: Pain & Trigger Points. The sternocleidomastoid is the prevailing muscle on both sides of the neck. If it is tense or carries trigger points, it can trigger pain in the head, ear, eye and face. Fortunately, it is possible to relieve the pain with a self-massage. The Sternocleidomastoid muscle is a long bilateral muscle of the neck that works by flexing the neck both anteriorly and laterally as well as rotate the head contralaterally towards the side of contraction. Congenital bilateral sternocleidomastoid contracture: a case report. Unilateral sternocleidomastoid muscle contracture causing torticollis and other secondary deformities such as facial scoliosis, plagiocephaly and scoliosis of cervical spine are well known. The aetiology and pathogenesis is still intriguing. Contraction of both sides together (bilateral contraction): flexes neck (draws head forward). Raises sternum, and consequently the ribs, during deep inhalation. Contraction of one side (single-sided contraction): tilts the head towards the same side. Rotates head to face the oppsite side (and also upwards as it does so). Unilateral (or one-sided) contraction of the sternocleidomastoid muscle produces lateral rotation of the head. Bilateral (both sides) contraction of the muscle produces flexion of the neck. It is innervated by the accessory nerve (the 11th cranial nerve), and anterior rami of spinal nerves C2 and C3.

• Palpate along the borders of the SCM Rectus capitis posterior major
  • A: Bilateral contraction  A contraction of both SCM muscles also flexes your neck, which brings your chin down in the direction of your breastbone. And bilateral SCM muscles contraction thrusts the chin forward when your head is level. Bilateral SCM muscle contraction simultaneously also plays a role in the breathing process. A unilateral contraction of the sternocleidomastoid muscle flexes the cervical vertebral column to the same side (lateral flexion) and rotates the head to the opposite side. A bilateral contraction elevates the head by dorsally extending the upper cervical joints.

    Sternocleidomastoid: Pain & Trigger Points. The sternocleidomastoid is the prevailing muscle on both sides of the neck. If it is tense or carries trigger points, it can trigger pain in the head, ear, eye and face. Fortunately, it is possible to relieve the pain with a self-massage.

    The sternocleidomastoid (SCM) muscle has a complex multidirectional pattern of movement. It is composed of clavicular (short head) and sternal (long head) divisions. Both divisions of the muscle attach to the head of the mastoid process and along the superior nucheal line. 1 The sternal division attaches below the sternum and the deeper clavicular branch attaches posteriorly and laterally onto the clavicle.
