Somatic Therapy for Complex Trauma & Related Patterns

Core Strokes® applies a developmental somatic trauma framework to complex trauma, attachment trauma, dissociation, complex PTSD, and borderline relational instability.

Written by Dirk Marivoet, founder of Core Strokes®

Part of the Core Strokes® Clinical Applications Series

Trauma expresses itself through distinct embodied patterns — including complex trauma, attachment trauma, dissociation, complex PTSD, and borderline relational instability.

This page explores how the Core Strokes® developmental somatic framework applies to specific trauma-related presentations through breath organization, fascial structure, intensity regulation, and relational co-regulation.

Rather than focusing primarily on diagnostic labels, Core Strokes® examines how developmental capacity has been shaped — and how it can be gradually restored through embodied therapeutic practice.

This developmental orientation allows trauma to be addressed at the level where it lives — in breath, tissue, intensity, and relationship.

→ How Core Strokes® Works with Trauma

Many individuals searching for therapy for complex trauma, attachment trauma, or dissociation are not looking for symptom suppression alone. They are seeking a body-based approach that addresses how trauma lives in breath, fascia, and relational experience. Core Strokes® offers a somatic developmental framework that restores embodied capacity rather than managing diagnosis alone.

Trauma Does Not Look the Same in Every Body

While trauma can be understood as restricted developmental capacity, it does not organize identically in every individual.

Different histories, attachment environments, and nervous system adaptations give rise to distinct patterns of embodied organization.

In clinical language, these patterns may appear as:

complex trauma
attachment trauma
dissociation
complex PTSD
borderline relational patterns

Core Strokes® does not begin with diagnostis.

It begins with embodied organization.

The central question is not:
“What disorder is this?”

But rather:
“How has capacity for safety, intensity, contact, and coherence been shaped — and how can it be restored?”

A Developmental Lens on Clinical Patterns

Within Core Strokes®, trauma-related presentations are understood across four primary developmental dimensions:

Breath organization – Is breathing restricted, collapsed, inflated, fragmented?
Fascial continuity – Is tissue braced, dense, porous, rigid, or fragmented?
Intensity tolerance – Can activation be held without overwhelm or shutdown?
Relational readiness – Can closeness, autonomy, and contact coexist?

Each “presentation” reflects a specific narrowing or reorganization within these domains.

The work is therefore not symptom-focused.
It is capacity-focused.

When developmental capacity expands, symptom patterns reorganize naturally.

Trauma-Related Presentations in Core Strokes®

Somatic Therapy for Complex Trauma

Chronic relational overwhelm, identity fragmentation, and cycles of activation and collapse.

Somatic therapy for complex trauma works with how prolonged relational overwhelm reorganizes breath, fascia, and identity over time.

Somatic therapy for complex trauma focuses on restoring breath continuity, fascial integration, and relational regulation across time.

Somatic Approach to Complex PTSD

Persistent hyperarousal, shutdown cycles, relational instability, and identity disruption.

Rather than focusing solely on symptom reduction, the work restores developmental regulation across breath, fascia, and relational field.

Core Strokes® and Borderline Patterns

Intensity dysregulation within contact — oscillations between closeness and rupture, activation and collapse.

Core Strokes® approaches borderline patterns developmentally, expanding intensity tolerance and relational sovereignty rather than suppressing emotion.

Beyond Diagnostic Categories

These presentations overlap.

An individual may express elements of several patterns simultaneously.

Core Strokes® therefore views them not as fixed identities, but as adaptive reorganizations within a developmental continuum.

Healing restores:

breath flexibility
fascial responsiveness
intensity capacity
relational coherence

When capacity expands, the presentation reorganizes.

Symptoms are adaptations.

Capacity is developmental.

Core Strokes® is a somatic trauma therapy framework rooted in breath regulation, fascial embodiment, intensity pacing, and relational co-regulation. It addresses complex trauma, attachment trauma, dissociation, and complex PTSD through a developmental model of embodied restoration.

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.

What is somatic trauma therapy and how does it work?

Somatic trauma therapy is a body-based approach to trauma treatment. It works with how traumatic experience becomes organized in breath, fascia, autonomic regulation, muscular tone, and relational response.

Trauma is not primarily a psychological event. It is an embodied survival reorganization that shapes how safety, intensity, and connection are experienced.

Rather than focusing only on thoughts or memories, somatic trauma therapy restores flexibility in breathing, continuity in tissue, regulation of activation, and stability in contact.

In Core Strokes®, this work unfolds within a developmental framework. Trauma is understood not only as dysregulation or unresolved memory, but as restricted access to essential capacities — the ability to breathe freely, remain present under activation, and stay connected in relationship.

The goal is not merely symptom relief. It is restoration of embodied capacity.

What is developmental trauma?

Developmental trauma refers to early relational experiences that overwhelm, disrupt, or insufficiently support the developing child over time.

Unlike shock trauma, which arises from a single overwhelming event, developmental trauma emerges through repeated patterns such as inconsistent attunement, emotional neglect, intrusive or mistimed contact, chronic instability, or prolonged relational stress during formative years.

From a Core Strokes® perspective, developmental trauma is not defined primarily by events. It is defined by restricted developmental capacities — including safety, contact, intensity regulation, autonomy, and relational coherence.

These restrictions are not stored only as memory. They are expressed in breathing patterns, fascial organization, tolerance for activation, and readiness for connection.

Healing therefore requires paced, relational, embodied work that gradually restores what was developmentally constrained.

How is complex trauma different from shock trauma?

Shock trauma typically results from a single overwhelming incident — such as an accident, assault, or medical emergency — that exceeds the nervous system’s capacity in a specific moment. Survival responses may remain incomplete, leaving the system locked in fight, flight, or freeze.

Complex trauma develops over time. It reflects repeated relational overwhelm, chronic unpredictability, emotional neglect, or prolonged exposure to stress without sufficient support.

Shock trauma often centers on unresolved survival activation.
Complex trauma reorganizes developmental capacity itself.

It affects breathing flexibility, tissue continuity, intensity tolerance, identity formation, and relational stability.

Core Strokes® works with both forms of trauma as disruptions of embodied organization. The aim is steady restoration of safety, continuity, vitality, and relational presence — not rapid catharsis.

How does Core Strokes® differ from EMDR or Somatic Experiencing?

EMDR primarily focuses on reprocessing traumatic memories so past events no longer intrude on the present.

Somatic Experiencing (SE) works mainly with shock trauma by regulating the nervous system and completing interrupted survival responses.

Core Strokes® stands in dialogue with these approaches while extending the work developmentally. Rather than centering memory processing or discharge, it examines how trauma becomes structurally organized in breath patterns, fascial continuity, intensity tolerance, and relational capacity over time.

The focus is not only resolution of past events — but restoration of developmental potential.

What role does breath play in trauma therapy?

In Core Strokes®, breath is not simply a calming technique.

Breathing is a developmental organizer. It shapes how safety, intensity, and relationship are experienced in the body.

The way a person breathes determines how much activation can be tolerated, how deeply emotion can be felt, and how stable connection can remain under intensity.

When trauma restricts breathing — through holding, collapse, or fragmentation — emotional depth and relational presence narrow.

Restoring breath continuity expands capacity.

Breath is not something to control.
It is the living pathway through which regulation and integration unfold.

How does Core Strokes® work with attachment trauma?

Attachment trauma is understood as a restriction of relational capacity that lives in the body — not merely as a psychological label.

Core Strokes® observes how breath responds to closeness, how fascia organizes around boundaries, and how intensity is tolerated within contact. Early relational disruptions shape tissue tone and breathing patterns long before they appear as conscious narratives.

Healing unfolds developmentally through pacing, co-regulation, and embodied relational experience.

Rather than categorizing attachment styles, the work restores capacities:

to remain present in closeness,
to tolerate distance without panic,
to sustain intensity without collapse.

The aim is relational sovereignty — the ability to remain oneself while in contact with another.

Is Core Strokes® only for people with trauma diagnoses?

No.

Core Strokes® is not limited to trauma treatment. It is a developmental framework for embodied regulation and relational integration.

While highly relevant for complex PTSD, attachment trauma, and chronic dysregulation, it also supports individuals seeking expanded emotional range, greater vitality, and more coherent relational presence.

The work addresses capacity — not diagnosis.

Is Core Strokes® effective for complex PTSD (C-PTSD)?

Yes. Complex PTSD often develops through prolonged relational instability, emotional neglect, or chronic overwhelm. Over time, the body adapts by narrowing its tolerance for safety, connection, and intensity.

Core Strokes® works gradually and developmentally to restore breathing flexibility, tissue continuity, activation capacity, and relational coherence.

The emphasis is careful pacing, breath continuity, and relational field awareness. Healing unfolds progressively — without overwhelm or forced catharsis.

The aim is stable embodied regulation over time.

Can somatic trauma therapy retraumatize someone?

Therapy becomes overwhelming when activation rises faster than capacity.

Retraumatization does not occur because emotion is felt.
It occurs when intensity exceeds available support and pacing.

In Core Strokes®, developmental readiness guides the process. Breath continuity, tissue responsiveness, and relational attunement are monitored carefully.

If activation rises too quickly, the work slows.

The goal is not exposure.
It is expansion of capacity.

Trauma healing is not about reliving the past. It is about restoring present-moment regulation — safely and progressively.

How does trauma affect the body long-term?

Trauma reshapes how the body regulates safety, intensity, and relationship.

Long-term effects may include:

• restricted or shallow breathing
• chronic muscular or fascial tension
• patterns of rigidity or collapse
• hypervigilance or persistent shutdown
• difficulty sustaining relational contact
• oscillation between activation and numbness

These are not character flaws. They are adaptive survival organizations.

When trauma is prolonged, it narrows essential developmental capacities — the ability to breathe fully, tolerate emotional intensity, remain present in closeness, or rest into safety.

From a Core Strokes® perspective, trauma reflects a restriction of embodied developmental organization.

Through restoration of breath flexibility, fascial continuity, activation tolerance, and relational coherence, the body gradually regains access to vitality and stability.

Long-term trauma patterns are not fixed traits.
They are adaptive organizations that can reorganize.

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.
