Posterior Upper Thoracic Complex
This module teaches the release of the Posterior Upper Thoracic Complex, a layered group of muscles between the shoulder blades. When these muscles enter spasm, they can compress spinal nerves and produce upper back pain, rib restriction, and postural fatigue.
The upper thoracic region is a transitional zone between the mobility of the cervical spine and the structural stability of the rib cage. It is designed to both support and adapt.
When functioning properly, this area allows for smooth transmission of force between the head, neck, and torso. It supports coordinated rib movement during breathing and distributes load efficiently through the spine.When dysfunction develops, this region does not typically fail at a single point.
Instead, it becomes progressively restricted across multiple layers of muscle.
Clients often experience:
• stiffness between the shoulder blades
• limited rotation or extension through the upper spine
• a feeling of compression or being “held” in the thoracic region• fatigue when maintaining upright posture
This is not a localized issue. It is a regional pattern of resistance that affects how the entire upper body moves and stabilizes.
Step 2
The Clinical Problem
Spasm of any of these muscles can cause impingement of the "long thoracic nerve", spinal nerves and even the spinal cord. Release these to relieve upper back pain.
A client reports pain between the shoulder blades, fatigue in the upper back, and dysfunction of specific organs, during fight, or flight - that I will mention soon.
Clinically, upper thoracic dysfunction presents as:
• pain in the upper back between the shoulder blades
• pain referred into head, neck and shoulder
• loss of thoracic flexibility during flexion
• loss of flexitility during rotation
• some restriction in breathing
Palpation reveals:
• which layers of muscle are in spasm
• decreased elasticity across multiple levels
• mobility of vertebra, ribs and scapula - which helps indicate which muscles are in spasm.
e.g, rhomboid spasm causes scapula to become immobile or serratus posterior superior causes ribs to become immobile. These muscles follow the same path, so mobility tests become essential for correct identification of which muscles are in spasm.
A key feature of this area is that the restriction can be caused by any of several layers of muscles being in spasm.
From superficial to deep, these layers are as follows:
• Trapezius
• Latissimus Dorsi
• Rhomboid layer (rhomboid major, rhomboid minor, levator scapulae)
• Serratus posterior superior
• Erector Spinae (semispinalis cervicis, semispinalis capitis, splenius cervicis, splenius capitus, longissimus thoracis, longissimus cervicis, longissimus capitis, iliocostalis thoracis, iliocostalis cervicis)
• Paraspinals
Any and all of these muscles will cause pain when they are in spasm, and limit mobility. They all have different insertions, but they all cause pain in between the shoulder blades. Release each of them, via process of elimination, and begin with the most sperficial layer and work your way to the deepest layer by releasing each of these muscles one at a time. The key muscle to release first is the infraspinatus, This is a genuine "Releasology hack." Do this first and the other muscles will be much easier to release.
By releasing each of these muscles the upper back will:
• rotate more freely
• flex while bending forward without effort
• distribute force efficiently
• become delightfully pain free
• breathing will become much easier.
The sympathetic nerves for several organs will be released, helping those organs work better during fight or flight.
These organs include:
• heart
• lungs
• liver
• gall bladder
• stomach
• spleen
• pancreas
These systems become blocked during sympathetic (fight or flight) mode because the sympathetic nerves that supply them are being compressed. by the muscles in this section. Release these muscles and release these nerves. Release these nerves to restore symnpathetic function to these organs. This means, that during periods of stress, these organs won't work well when these muscles are in spasm. This modality is about more than freeing pain. Releasing these muscles that cauase pain in the upper back also restores better organ
If back pain persists, one of these layers is in spasm. Release them all and pain will stop.
Step 3
Why This Happens
The Root Cause of Muscle Spasm
The upper thoracic complex is particularly vulnerable to dysfunction due to its layered structure and constant functional demand.
This region must:
• support the head and cervical spine
• stabilize the shoulder girdle
• coordinate with the rib cage during breathing
• transmit force between the upper and lower body
To accomplish this, multiple layers of muscle remain active throughout the day.
When fatigue, postural strain, or repetitive patterns are introduced, these muscles can enter a state of sustained contraction.
Because the region is layered:
• superficial muscles tighten to stabilize
• deeper muscles compensate and become restricted
• tension accumulates across multiple levels
Over time, the layers lose their ability to move independently and begin to function as a single unit.
From a Releasology perspective, this represents a disruption in conduction across layers.
Force is no longer transmitted efficiently. It becomes absorbed and restricted within the tissue.
Prana, understood as the integrated flow of force, fluid, and information, becomes limited in its movement through this region.
The result is a system that:
• holds tension
• resists movement
• and loses its ability to adapt
This is why the pattern feels persistent and difficult to resolve.
Step 4
Anatomy
The upper thoracic complex is composed of multiple layers of muscle
working together to stabilize and move the spine and rib cage.
These layers can be understood as:
Superficial Layer
• Trapezius
• Rhomboid major and minor
These muscles connect the spine to the scapula and control gross positioning of the shoulder girdle.
Intermediate Layer
• Serratus posterior superior
• Upper intercostals
These muscles assist in rib movement and breathing, linking spinal motion to respiratory function.
Deep Layer
• Erector spinae
• Transversospinalis group (multifidi, rotatores)
These muscles provide segmental stability and fine control of spinal movement.
Each layer must:
• glide independently
• transmit force efficiently
• respond dynamically to movement
When healthy, the system behaves as a coordinated, responsive structure.
When dysfunctional, the layers lose independence and become bound together.
Step 5
Palpation and Tissue Assessment
Assessment of the upper thoracic complex requires awareness of both layering and precision.
This is not a region that can be understood through surface contact alone.
The practitioner must learn to distinguish between layers and identify where the system is truly being held.
Layered Palpation:
Begin at the surface and progress gradually.
At the superficial level:
• trapezius and rhomboids may feel dense or resistant
As pressure is applied:
• superficial tension may soften
• deeper layers may remain restricted
• the tissue may feel thick, stacked, or non-yielding
The key questions are:
👉 “Do you feel tight fibers?”
and:
👉 “Does it restrict the bones it attaches to?”
Cross-Fiber Assessment
At each layer, use cross-fiber palpation:
• move perpendicular to the direction of the muscle fibers
• feel for resistance versus glide
• identify areas that behave like solid bands rather than fluid tissue
Restricted fibers will feel:
• dense
• string-like
• resistant to deformation
Healthy tissue will feel:
• responsive
• compressible
• able to change under pressure
Layer Recognition
As you palpate, begin to distinguish layers:
• superficial layers move broadly
• deeper layers feel more specific and localized
• restricted layers feel bound together rather than separate
A key indicator of dysfunction is:
👉 the inability of the layers to glide independently
Instead, the region behaves as a single, rigid structure.
Scapular Observation
Observe the scapula during palpation.
Focus on the inferior angle:
• if it appears held down against the ribs, the system is restricted
• if it moves freely and lifts, the system is more responsive
This provides immediate visual feedback about:
👉 the state of the underlying tissue
Amsa Marma Identification (Infraspinatus)
Within this region, special attention should be given to the infraspinatus, which corresponds to Amsa Marma.
This is not a broad area, but a precise, finger-sized point located within the muscle.
Palpation of this point should be:
• specific
• controlled
• intentional
When this point is restricted, it may feel:
• dense
• sensitive
• resistant to pressure
Clinically, this point often acts as a control point within the system.
When it is in spasm:
• the scapula loses its ability to glide
• surrounding muscles become compensatory
• deeper thoracic layers become more resistant
Functional Assessment
As you palpate, consider:
• Which layer is most resistant?
• Does the tissue soften or remain fixed?
• Is the restriction local, or does it influence surrounding areas?
You are not just identifying tightness.
You are identifying:
👉 where conduction is most disrupted
Releasology Perspective
A muscle in spasm is not simply tight—it is non-conductive.
In this region, dysfunction presents as:
• layers that do not separate
• tissue that does not yield
• force that does not transmit
Your role is to locate:
👉 the point where the system is most resistant
This is where the release must occur.
Step 6
Neurological Consequences
The upper thoracic complex plays a critical role in shaping the neurological environment of the upper body.
When this region becomes restricted across multiple layers, the effects are not typically dramatic, but they are pervasive and influential.
Nerve impingements:
• long thoracic nerve
- spinal nerves C1 through T9
• spinal cord in this region
Proprioceptive distortion
The thoracic spine provides constant feedback to the nervous system regarding:
• posture
• orientation
• movement through space
When the layers of this region become bound together:
• proprioceptive input becomes less accurate
• the system loses clarity in positioning
• movement becomes less efficient and more effortful
Clients may not describe this as neurological, but they experience it as:
👉 stiffness, fatigue, and lack of coordination
Increased baseline muscle spasm and loss of tone
Layered spasm in this region creates a condition of constant low-level activation.
The nervous system interprets the restriction as instability and responds by:
• decreasing muscular tone
• reinforcing protective patterns - spasm
• limiting available movement
This creates a feedback loop:
• restriction → increased fatigue → increase spasm → restriction
The system becomes held in a state of chronic spasm.
Respiratory influence
Because of the involvement of the ribs and intercostal muscles, thoracic restriction affects breathing.
When the layers do not move freely:
• rib expansion is limited
• breathing becomes shallow
• accessory muscles may overcompensate
This can subtly alter the nervous system by:
• maintaining a mild stress response
• reducing the system’s ability to fully relax
Conduction and system integration
From a Releasology perspective, this region represents a major pathway for conduction between the upper and lower body.
When the layers are free:
• force transmits efficiently
• movement is coordinated
• awareness is distributed
When the layers are restricted:
• force is absorbed rather than transmitted
• movement becomes segmented
• awareness becomes localized
Prana, understood as the integrated flow of force, fluid, and information, becomes limited in its ability to move through this region.
The system loses its sense of continuity.
Functional Impact
The result is not a single symptom, but a global change in how the system feels and functions.
Clients may experience:
• persistent stiffness that does not resolve with stretching
• fatigue during upright posture
• reduced ease of movement
• a sense of compression through the upper back
This region often acts as a bottleneck.
Even when other areas are treated, unresolved thoracic restriction can limit overall progress.
Resolution
When the layers of the upper thoracic complex are released:
• proprioceptive clarity improves
• baseline muscle tone increases
• breathing becomes more natural
• movement becomes coordinated
• the ability of these muscles to relax is restored
• strength returns
Clients often report:
• a sense of lightness through the upper body
• easier posture without effort
• deeper, more relaxed breathing
• improved overall fluidity
Releasology Perspective
The neurological consequences of this pattern are not caused by direct compression, but by loss of integration across layers.
When those layers are restored:
• conduction improves
• Prana moves freely
• the system regains coherence
The upper thoracic complex shifts from a point of resistance to a pathway of transmission.
Step 7
Technique Demonstration
Watch the following technique demonstration carefully.
Your goal is not to passively watch, but to study how the practitioner works through layers.
Watch the demonstration at least twice before attempting the technique.
First Viewing — Understand the Flow
Focus on the overall structure:
• where the practitioner begins (Amsa / infraspinatus region)
• how they position their body relative to the client
• the sequence of movement across the upper thoracic region
• how they transition between layers
Do not focus on details yet.
Understand the flow of the session.
Second Viewing — Focus on Mechanics
Now study the details:
• practitioner stance — grounded and stacked
• hand placement — precise, not searching
• direction of pressure — across the fibers, not just into the tissue
• how cross-fiber palpation is used to identify restriction
• how the practitioner avoids pushing deeper and instead differentiates layers
Pay close attention to:
👉 where the tissue resists
👉 how the practitioner refines contact into that point
Observe the Release
Watch for the moment of change:
• how long the practitioner maintains pressure
• how the tissue shifts from dense → responsive
• how the scapula begins to move more freely
• how the practitioner does not increase force, but waits
This is where the technique becomes clear.
What to Look For
As you watch, ask yourself:
• Where is the primary restriction?
• Which layer is being engaged?
• Is the practitioner moving deeper, or more precisely?
• When does the system begin to yield?
This is not a technique of force.
It is a technique of layered perception and precision.
Preparation for Practice
Before moving on:
• visualize your hand placement
• understand where you will begin (Amsa region)
• be clear on how you will move across the fibers
You are not expected to perform this perfectly.
But you should be able to:
👉 locate the correct region
👉 apply controlled pressure
👉 recognize resistance in the tissue
Releasology Perspective
The demonstration is not showing where to press.
Step 8
Worksheet Exercise
Digital Drawing of the Upper Thoracic Layers
In this exercise, you will open a unique upper back pdf for each muscle layer, using your phone. Then, using a drawing tool in SMS or any way you want, use a red line with your pen tool to draw in each muscle using red lines to represend the direction of the fibers of these muscles. After drawing a layer, fill in the origin, insertion, movement and innervation of each muscle in the group, onto the provided skeletal worksheet. Save your drawing before something goes wrong. Upload and click submit!
This is a required submission.
Your goal is to demonstrate that you understand:
• the layered organization of the region
• the direction of muscle fibers
• how these layers relate to movement and restriction
• the location of the Amsa Marma (infraspinatus)
Step 1: Download the Worksheet
Download the provided PDF skeleton image on this page.
Save it to your device.
Step 2: Open in a Drawing Tool
Open the PDF using a drawing or markup tool on your phone or tablet.
Use a red pen or pencil tool.
Step 3: Draw the Layers (Red Lines)
Draw directly over the skeleton image.
You are not drawing every detail.
You are showing layer direction and coverage.
Trapezius (Superficial Layer)
• Draw from midline outward to the shoulder
• Show broad, lateral fiber direction
• Fill approximately 80% of the muscle area
Latissimus Dorsi
• Draw fibers running upward and outward toward the arm
• Include its influence on the inferior angle of the scapula
👉 Note on your drawing:
• “Held down = restriction”
• “Free = normal movement”
Rhomboid Layer (Levator Scapulae, Rhomboids)
• Draw from spine to medial border of the scapula
• Show inward pull toward the spine
Serratus Posterior
• Draw oblique lines from spine to ribs
• Keep this layer lighter but accurate
Erector Spinae
• Draw vertical columns along the spine
• Indicate long, continuous fiber direction
Paraspinals
• Add smaller, short lines near the spine
• Represent segmental control
Intercostals
• Draw diagonal lines between ribs
• Show direction of rib-to-rib connection
Step 4: Identify Amsa Marma (Infraspinatus)
Locate and mark a finger-sized point within the infraspinatus region.
Label it:
👉 “Amsa Marma”
This point must be:
• precise (not a large shaded area)
• clearly located on the posterior scapula
Step 6: Add Required Labels
Label the primary structures with simple flank lines:
• Muscle names in group
extra (if neccesary for each muscle):
• Origin
• Insertion
• Movement
• Innervation
Keep labels brief and readable.
Step 6: Save and Upload
Save your completed worksheet.
Upload your file in this section.
Submission Standard
Your work must clearly show:
• correct layering of the region
• accurate fiber direction
• muscle lines need to be drawn accurately to origin and insertion attachments
• correct identification of Amsa Marma
This is not graded on artistic skill.
It is graded on:
👉 accuracy
👉 clarity
👉 understanding
Releasology Reflection
Before submitting, ask yourself:
• Which layer is most likely to resist first?
• Where would you begin your treatment?
• How does Amsa influence the rest of the system?
You may add 1–2 short notes directly to your image.
Purpose of This Exercise
This exercise trains you to:
• see the body in layers
• understand structure before touch
• identify where the system is held
If you cannot draw the layers 2-dimensionally, you will have trouble palpating them 3-dimensionally.
Step 9
Practice Assignment
Clinical Skill Development
In this step, you will perform the Upper Thoracic Complex modality on a practice client.
Your goal is not to force through tissue, but to demonstrate:
• palpate and find each tight muscle in each layer
• use correct body mechanics and hand placement
• stretch, and perform Yang compression of each muscle correctly
• use the Yin pulse to release each muscle - the muscle will visibily relax while and after Yin flow
• be sure to double check each layer and release any remaining muscles.
• feedback from your client should let you know when their pain levels have truly subsided in these muscles.
Preparation
Before beginning:
• review the Technique Demonstration (Step 7)
• review your Worksheet Exercise (Step 8)
• visualize the layers and their directions
• be clear on where you will begin
You should understand:
👉 you are not working “into” the body
👉 you are working across layers to find resistance
Client Setup
• Client positioned comfortably prone on a massage table
• Client must not wear any clothing above the waist
• Upper thoracic region exposed
• Scapula visible and accessible
Explain to your client:
• they may feel pressure, but not pain
• they should remain relaxed and breathe normally
Execution Sequence
1. Entry Point — Amsa (Infraspinatus)
Begin at the Amsa Marma (infraspinatus).
• establish precise, finger-sized contact
• apply slow, controlled pressure
• use cross-fiber palpation to identify resistance
Do not rush past this point.
👉 This is your entry into the system
2. Scapular Assessment
Observe and feel:
• does the inferior angle move freely?
• does it appear held down against the ribs?
If restricted:
👉 remain until the tissue begins to yield
3. Layer-by-Layer Progression
Once the system begins to respond:
Move progressively through layers using cross-fiber palpation:
• trapezius (broad, superficial)
• latissimus dorsi (diagonal, influencing scapula)
• rhomboid layer (spine to scapula)
• deeper spinal layers (vertical chains)
At each layer:
• move across the fibers
• identify the most resistant band
• maintain steady pressure
Do not push deeper.
👉 Refine your contact instead
4. Recognizing the Primary Restriction
Throughout the session, ask:
• which layer is holding the system?
• does the tissue yield or remain solid?
The primary restriction will feel:
• dense
• non-yielding
• resistant to change
This is where you remain.
What You Are Looking For
During the session:
• transition from resistance → softness
• separation between layers
• improved scapular movement
• increased tissue responsiveness
After the Release
Observe:
• increased thoracic extension
• improved rotation
• freer scapular motion
Ask your client:
• does the area feel lighter?
• is movement easier?
• does breathing feel more open?
Practice Standard
You are expected to demonstrate:
• correct identification of Amsa
• effective cross-fiber palpation
• ability to differentiate layers
• patience — not force
Releasology Perspective
This modality is not about depth.
It is about:
• entering through a control point
• working across layers
• restoring the ability to release to each layer of muscle
• this process naturally frees adhesions between these layers, but mobililization - meaning, pick up the scapula, and move it around, use both hands and test the ribcage by dropping pressure into your palms carefully but firmly hald over the ribcage and scapula, but never, never, never, over the spine or vertebra.
Step 10
Treatment Recording
In this step you will record yourself performing the upper thoracic complex release techniques 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
