04 Suboccipital-Semispinalis Complex
This module teaches the release of the Suboccipital–Semispinalis Complex, a group of deep muscles at the base of the skull that control fine movements of the head and neck. When these muscles enter spasm, they can contribute to tension headaches, dizziness, and compression near the vestibulocochlear nerve.
Step 1
Understanding the Problem
Step 2
The Clinical Problem
The Clinical Problem
A client arrives complaining of headaches at the base of the skull, dizziness, ear pressure, ringing in the ears and/or loss of hearing.
Despite treatment of the neck and shoulders, and other treatments, the symptoms continue.
The source often lies in the deep semispinalis muscles and the suboccipital muscles, which can compress the vestibulocochlear nerves which pass from the inner ear canal to the foramen magnum and between the the occipital bone and the Atlas bone. When the semispinalis or sub occipital muscles are in spasm, the Atlas tilts in exactly the way that causes this impingement. This is the most common cause of dizziness, loss of balance, loss of hearing, ringing in the ears and other vestibulocochlear impingement related symptoms. There are cases where clients actually have an infection of the inner ear and this will cause this, but it is relatively rare in the real world. .
Because the space is narrow it only requires a small degree of tilting to cause this, so we are lucky it doesn't happen all of the time.



Spasm of the semispinalis and suboccipital muscles can misalign the upper cervical column resulting in impingement of the vestibulocochlear nerve where it passes between the Atlas and Occipital bones
This is why many tension in the back of the head and neck is always present when vertigo, ringing in the ears or hearing loss are present.
Step 3
Why This Happens
The Root Cause of Muscle Spasm
Muscle spasm is not tightness.
It is not a flexibility problem.
A muscle spasm is an involuntary contraction caused by fatigue of the muscle cells.
When metabolic fatigue accumulates inside the muscle fibers, the cells lose their ability to release calcium and the muscle becomes locked in contraction.
What Happens Inside the Muscle
When enough fibers cross this metabolic threshold, the muscle loses its ability to relax and becomes locked in spasm.
This persistent contraction:
• reduces blood flow
• traps metabolic waste products
• increases neural irritation
The muscle becomes a localized metabolic crisis.
Why the Scalenus Creates Neurological Symptoms
The scalenus anterior sits at the entrance to the thoracic outlet.
When the muscle becomes locked in spasm, it narrows the space through which several neurological and vascular structures must pass.
Even small changes in this space can interfere with normal nerve and blood flow.
Why Symptoms Appear Far From the Neck
As the muscle contracts and shortens, blood flow is reduced and neural conductivity becomes impaired.
This is why symptoms can appear far from the neck itself.
Migraines, arm symptoms, breathing disturbances and nervous system irritation may all originate from this muscular bottleneck.
Releasology does not chase symptoms.
It releases the cause.

Scalenus anterior (red) running from the cervical vertebrae to the first rib. Spasm in this muscle narrows the thoracic outlet and compresses nearby neurological structures.
Step 4
Anatomy
The scalenus anterior originates from the transverse processes of the cervical vertebrae and inserts on the first rib.
Its position places it directly adjacent to several critical neurological and vascular structures.
Structures influenced by scalenus anterior spasm include:
• Brachial plexus
• Phrenic nerve
• Vagus nerve
• Carotid artery
• Cervical nerve roots
Because these structures pass directly beside the muscle, even a small contraction can produce significant neurological effects.

Step 5
Accessory Muscles
The scalenus anterior does not act alone.
It functions as part of a coordinated group of cervical stabilizers.
Primary muscle:
• scalenus anterior
Accessory muscles:
-
Scalenus anterior
-
Scalenus medius
-
Scalenus posterior
-
Sternocleidomastoid
-
Levator scapulae
-
Upper trapezius
These muscles often become painful and hypertrophic because they are compensating for instability created by anterior cervical collapse.
Step 6 — Neurological Consequences
When the scalenus anterior enters spasm, it can compress multiple neurological pathways.
Anterior cervical spasm traps:
-
Cervical nerve roots
-
Sympathetic fibers
-
Autonomic signaling pathways
This produces symptoms such as:
• Migraines
• Neck pain
• Radiating arm symptoms
• Nervous system irritation
• Breathing changes
• Nausea in severe cases
When cervical pain is accompanied by nausea, vagus nerve involvement should be suspected.
Understanding these neurological relationships allows the practitioner to identify the correct release protocol.
Step 7 — Technique Demonstration
Watch the following technique demonstration carefully.
Pay attention to:
• practitioner stance
• hand placement
• body mechanics
• direction of pressure
• the Yang–Yin release cycle
Releasology pressure is not force.
Pressure is information delivered through correct body mechanics.
The practitioner applies controlled Yang compression until the tissue reaches the release threshold.
Pressure then softens into the Yin phase, allowing the muscle fibers to relax.
Step 8 — Worksheet Exercise
Download the worksheet below.
Using a red drawing tool on your phone or tablet:
-
Trace the attachments of the scalenus anterior.
-
Identify the cervical vertebrae involved.
-
Mark the first rib insertion.
-
Review the surrounding neurological structures.
Save the image to your device.
Upload the completed worksheet in the next step.
Mastery of anatomy is required for precise clinical work.
Step 9
Practice Assignment
Clinical Skill Development
Set up a massage table and recruit a practice subject for your first scalenus anterior release.
If possible, choose a subject experiencing::
• neck pain
• migraines
• arm symptoms
• breathing restriction
Watch the technique video again and pause frequently.
Practice slowly until you can clearly feel:
• correct finger positioning
• correct practitioner body mechanics
• the Yang engagement phase
• the Yin release phase
The goal is not force.
The goal is precise engagement of the tightest fibers.
Once you have performed the release successfully, proceed to the next step.
Step 10
Technique Recording
In this step you will record yourself performing the scalenus anterior release technique so your form and body mechanics can be evaluated.
You will need:
• a massage table or treatment surface
• a practice subject
• a tripod or stable support for your phone or camera
• good lighting so your hand placement is clearly visible
Position the camera so that the following are clearly visible in the video:
• your hand placement on the client
• your body mechanics and posture
• the direction of pressure you apply
• the client’s neck and shoulder region during the release
The video should show the entire treatment sequence, from initial contact to release.
Record yourself performing the scalenus anterior release technique so your form and body mechanics can be evaluated.
☑ correct finger placement
☑ practitioner body mechanics
☑ the Yang engagement phase
☑ the Yin release phase
The video should show the full treatment sequence from initial contact to muscle release.
Upload your video for instructor review.
Your instructor will confirm that the technique is performed safely, accurately, and according to the Releasology method.
This step allows your instructor to confirm that the technique is being performed safely, accurately, and according to the Releasology method.
Step 11
Client Testimonial
Ask your practice subject to rate their symptoms before and after the treatment using a 0–10 scale.
Record a brief testimonial video including::
☑ symptom description
☑ before score
☑ after score
☑ changes they experienced
Upload the testimonial video.
Documenting real clinical outcomes is an essential part of Releasology training.
