Trauma & Development
Understanding Shock Trauma, Developmental Trauma, and Complex PTSD Through a Somatic Framework
Written by Dirk Marivoet, founder of Core Strokes®
Trauma is often described as a single overwhelming event.
However, from a developmental and somatic trauma therapy perspective, trauma is not only what happened — it is how the body reorganized in response.
Trauma can unfold gradually through relational misattunement, chronic stress, attachment disruption, or prolonged exposure to unpredictability. What becomes significant is not merely the event, but the way the organism adapted.
Core Strokes® is a developmental and body-based trauma framework that integrates:
- shock trauma
- developmental trauma
- attachment trauma
- complex PTSD
- breath regulation
- fascial embodiment
- intensity tolerance
- relational co-regulation
Rather than treating trauma solely as unresolved memory, Core Strokes® understands trauma as a restriction of embodied developmental capacity — the capacity to feel safe, tolerate intensity, remain present in relationship, and move fluidly between activation and rest.
Trauma as Restricted Development
Trauma does not only disrupt memory.
It reorganizes the body.
Over time, this reorganization may appear as:
- restricted breathing patterns
- chronic muscular or fascial tension
- collapse or rigidity
- hypervigilance or shutdown
- difficulty sustaining relational contact
- oscillation between activation and numbness
These are not defects.
They are adaptive reorganizations of the nervous system and connective tissue network.
From a Core Strokes® perspective, trauma narrows access to essential capacities:
- the ability to breathe freely under activation
- the ability to remain connected in closeness
- the ability to tolerate intensity without fragmentation
- the ability to rest into safety
Healing, therefore, is not merely symptom reduction.
It is developmental restoration.

Shock Trauma
Shock trauma typically results from a single overwhelming event — such as an accident, assault, or medical emergency — that exceeds the nervous system’s capacity in that moment.
Its hallmarks often include:
- incomplete survival responses
- frozen defensive activation
- intrusive memories or flashbacks
- sudden autonomic dysregulation
Many trauma therapies focus effectively on resolving these acute shock patterns.
Core Strokes® includes this dimension but situates it within a broader developmental map. Shock trauma is understood as one form of interruption in the organism’s rhythmic organization.
Developmental & Attachment Trauma
Developmental trauma unfolds over time.
It arises through repeated relational misattunement, emotional neglect, intrusive contact, chronic instability, or insufficient support during formative years.
Unlike single-incident trauma, developmental trauma reorganizes:
- identity formation
- relational readiness
- intensity tolerance
- breath flexibility
- fascial continuity
It shapes how safety and connection are lived in the body.
Rather than categorizing attachment styles, Core Strokes® works with how relational capacity appears somatically:
- Can closeness be sustained?
- Can intensity be held without collapse?
- Can autonomy coexist with connection?

Complex Trauma
Complex trauma reflects prolonged exposure to relational overwhelm or chronic unpredictability.
It often includes:
- cycles of activation and collapse
- fragmentation of identity
- emotional instability
- dissociation
- difficulty with sustained trust
From this perspective, complex trauma is not simply accumulated shock.
It is a broader reorganization of developmental capacity.
Breath may become shallow or held.
Fascial tissue may become rigid, dense, or fragmented.
Intensity may feel either unbearable or inaccessible.
The work, therefore, must be gradual and developmental.

A Unified Developmental Perspective
While shock trauma, developmental trauma, and complex trauma are often treated as separate categories, Core Strokes® understands them as variations in how embodied developmental organization becomes disrupted.
The difference lies not only in events, but in how breath, fascia, intensity tolerance, and relational capacity were shaped over time.
Both shock and complex trauma represent interruptions in the organism’s developmental rhythm — and both can be addressed through restoration of embodied capacity.
Breath as a Developmental Organizer
In Core Strokes®, breath is central.
Breathing is not treated merely as a calming tool.
It is understood as a developmental organizer — shaping how safety, intensity, and relationship are embodied.
When trauma restricts certain breathing patterns:
- emotional depth becomes limited
- vitality decreases
- relational presence narrows
Restoring breath flexibility restores developmental range.
This understanding is articulated through the Energetic Breath Cycle™, which maps how breathing phases correspond to emotional and relational capacities.
Fascia and Embodied Memory
Trauma does not live only in narrative memory.
It also lives in tissue organization.
The fascia — the body’s connective matrix — reflects patterns of protection, bracing, fragmentation, or collapse. These patterns can be perceived phenomenologically through the Fascia Texture Typology™.
Rather than classifying tissue anatomically, this approach reads how lived experience appears through texture, density, elasticity, and responsiveness.
This perspective is further developed through Neurofascial Encoding™, which describes how experience becomes embodied and how reorganization unfolds through relational, breath-based work.
From Trauma Repair to Developmental Restoration
Core Strokes® integrates shock trauma resolution and developmental trauma repair within a unified developmental map.
Clinical work proceeds through:
- breath continuity
- fascial responsiveness
- intensity pacing
- relational co-regulation
The aim is not catharsis.
It is expansion of capacity.
Rather than reliving the past, the work strengthens present-moment embodied organization so that previously overwhelming experience can be metabolized safely.
Healing unfolds as:
Safety → Capacity → Coherence → Integration
Trauma Work as Developmental Maturation
Trauma is not the endpoint of this framework.
As developmental capacity expands, work naturally moves beyond repair toward integration:
- embodied polarity
- pelvic–heart coherence
- relational sovereignty
- creative vitality
- soul-level integration

A Developmental Perspective on Healing
Core Strokes® understands trauma not as pathology, but as adaptation.
The body did what it had to do.
And what was restricted can be gradually restored.
Through breath, fascia, intensity pacing, and relational presence, developmental organization can reorganize.
Not by force.
Not by exposure.
But by expanding embodied capacity — one phase at a time.
From here, you can explore the Core Strokes® training, read more about the breath phases, or learn how practitioners work with this approach in practice.

Continue the Core Strokes® Trauma Series
This article is part of an ongoing series exploring trauma as a developmental and embodied process within the Core Strokes® framework.
The series examines how trauma restricts access to core capacities — and how these capacities are restored through different dimensions of embodied experience:
- Trauma as Restricted Development (this article)
- Breath and Trauma — how breathing capacity organizes safety and regulation
- Fascia and Trauma — how experience becomes embodied in tissue
- Intensity as Capacity — meeting strong activation without overwhelm
- Relationship as a Developmental Capacity — how regulation emerges in contact
Together, these texts describe how safety, vitality, and contact are restored through breath, fascia, intensity, and relational presence as one integrated developmental process.
Frequently Asked Questions About Somatic Trauma Therapy and Core Strokes®
Below you’ll find clear answers to common questions about somatic trauma therapy, complex PTSD (C-PTSD), attachment trauma, and the Core Strokes® developmental framework.
Trauma reshapes the body’s organization over time.
Healing restores capacity.
Integration matures that capacity into coherent presence.
Closing Perspective
Core Strokes® is a developmental somatic framework rooted in breath, fascia, and relational regulation.
It does not simply treat trauma.
It restores embodied capacity.From that restoration, integration unfolds.
And from integration, relational maturity becomes possible.
