Regulation in Core Strokes®
How Living Organisation Modulates Activity in Changing Conditions
By Dirk Marivoet, Founder of Core Strokes®· Psychotherapist · Teacher · Author
Regulation — Core Definition
Regulation is the process through which activity is modulated in relation to changing internal and external conditions.
Modulation may involve increasing, decreasing, maintaining, redirecting, containing or interrupting activity. These changes can occur across physiological, sensory, motor, emotional, attentional, behavioural and relational processes.
Regulation is therefore inherently relational. Activity is not regulated according to an abstract ideal but in relation to conditions.
Running requires a different organisation from resting. Speaking publicly requires different activation from falling asleep. Protecting a boundary may require increased muscular and emotional mobilisation, while receiving support may permit activity to diminish. A demanding task may require sustained attention even when fatigue is present.
No single level of activation is therefore intrinsically regulated.
Regulation concerns whether activity can be modulated in ways that participate adequately within changing conditions.
Regulation Is Not the Same as Calm
One of the most common misunderstandings of Regulation is to equate it with calmness.
Calm can be appropriate, but it is only one possible regulatory configuration.
A person facing immediate danger may require rapid mobilisation. Someone defending a boundary may need increased muscular activity, a stronger voice and greater emotional intensity. Excitement, vigorous movement, sexual arousal, focused concentration and passionate engagement can all involve substantial activation without necessarily representing regulatory failure.
Conversely, apparent calm does not necessarily demonstrate flexible Regulation. Reduced movement, quiet breathing or limited expression may sometimes reflect exhaustion, inhibition, withdrawal, immobilisation or a highly constrained protective organisation.
The amount of visible activation therefore cannot by itself establish how Regulation is organised.
Within Core Strokes®, Regulation is understood functionally and contextually: what is being modulated, in relation to which conditions, and with what range of possible responses?
Regulation Is Broader Than Autonomic Regulation
Autonomic processes are important to Regulation, but Regulation within Core Strokes® is not synonymous with autonomic nervous system regulation.
Changes in heart rate, respiration, vascular activity, digestion and other autonomic processes participate continuously in embodied adaptation. Yet human Regulation also involves sensory attention, movement, muscular organisation, emotional expression, behavioural inhibition and activation, cognition, environmental orientation and relational participation.
These processes interact, but they should not be collapsed into a single physiological explanation.
A person may deliberately slow their movement, redirect attention, change position, ask another person to stop, seek support, leave an interaction or increase physical effort. Each of these actions may alter wider physiological conditions, but their regulatory significance cannot be reduced solely to autonomic state.
Core Strokes® therefore approaches Regulation organisationally. The nervous system is central to embodied regulation, but Regulation concerns the wider modulation of living activity across interacting processes.
Regulation as a Living Process
Regulation occurs continuously because the conditions of living continually change.
Even apparent stillness requires ongoing modulation. Postural activity adjusts to gravity. Breathing changes from moment to moment. Attention shifts. Temperature, circulation and metabolic activity are continually regulated. Environmental sounds, internal sensations and relational events alter what becomes relevant.
During movement or interaction, these demands become even more visible. Walking over uneven ground requires continual adjustments in balance and muscular activity. Conversation requires modulation of attention, voice, timing and response. Emotional engagement may require simultaneous changes in breathing, posture, expression and behavioural restraint or mobilisation.
Regulation is therefore not an occasional corrective process that begins when something goes wrong.
It is an ongoing dimension of living organisation.
What varies is how activity is modulated, which processes participate, how quickly organisation can change and how broad a repertoire remains available as conditions develop.
Regulation and Continuity
Continuity concerns how living organisation remains ongoing through changing conditions. Regulation contributes to this process by modulating activity as those conditions change.
Maintaining Continuity does not require maintaining the same level of activation. On the contrary, persistence often depends upon change.
The organism increases effort when demands rise, reduces activity when recovery becomes possible, redirects attention when circumstances change and alters behaviour when previous responses are no longer adequate.
Regulation therefore supports Continuity through variation rather than sameness.
At the same time, regulatory patterns themselves may become relatively stable. A person may repeatedly reduce emotional expression, maintain heightened vigilance or increase control in situations that resemble previous difficulty. Such patterns may preserve Continuity even when they constrain the range of available responses.
The relevant question is consequently not whether Regulation preserves stability, but how activity is modulated in ways that allow organisation to continue under changing conditions.
Regulation and Pulsation
Regulation and Pulsation are closely related but distinct Organisational-Dynamic Principles.
Pulsation concerns movement among changing states, directions and intensities. Regulation concerns how activity is modulated in relation to changing internal and external conditions.
Pulsation makes variation perceptible. Regulation participates in shaping the range, timing and organisation of that variation.
Activation may increase, remain elevated, diminish or change direction. Regulation may amplify this movement, attenuate it, maintain it, interrupt it or permit it to develop further according to the conditions being encountered.
Regulation therefore should not be understood as opposing activation. It participates in how activation changes.
A broad pulsatory range may require substantial regulatory capacity precisely because the organism must remain capable of modulating activity across very different states.
Regulation and Propagation
Propagation concerns how local change becomes consequential elsewhere within living organisation. Regulation concerns how the activity associated with such change is modulated.
If every local event produced unrestricted consequences throughout the organism, flexible participation would become difficult. Regulation can influence whether activity remains relatively local, becomes amplified, extends more widely, is redirected or gradually diminishes.
At the same time, propagated changes continually alter the conditions requiring Regulation. A local pain may change posture and movement. A relational cue may alter attention, breathing and muscular activity. A change in breathing may become related to wider shifts in movement or emotional experience.
Regulation therefore participates in shaping the conditions under which Propagation occurs, while Propagation continually generates changing conditions to which regulatory processes respond.
The principles are distinct but recursively related.
Regulation and Differentiation
Differentiation increases the specificity with which Regulation can occur.
When different sensations, emotions, impulses and environmental cues remain distinguishable, they need not all recruit the same response. A person may distinguish physical effort from danger, excitement from fear, another person’s distress from their own, or an impulse from an action.
Such distinctions can increase the available regulatory repertoire.
At the same time, Regulation contributes to the conditions under which Differentiation remains possible. Under intense activation, exhaustion or threat, distinctions that are normally available may diminish as organisation becomes more global.
Neither principle therefore simply precedes the other.
Differentiation can permit more specific modulation, while Regulation can preserve conditions within which relevant distinctions remain available.
Regulation and Integration
Integration concerns how differentiated processes become coordinated within a larger organisation without losing their distinction. Regulation concerns how activity within that organisation is modulated as conditions change.
Integrated organisation can increase regulatory possibilities because multiple sources of information can participate in response. Bodily sensation, environmental perception, emotion, thought, movement and relational information may all contribute to how activity is modulated.
Regulation also affects which processes remain available for Integration. During intense demand, organisation may narrow and temporarily prioritise some processes over others. When conditions change, a broader range may again become available.
Regulation and Integration therefore interact continuously.
Integration concerns coordination among differentiated processes. Regulation concerns modulation of activity within and across those relationships.
Regulation and Self-Organisation
Regulation and Self-Organisation are also closely related.
Regulatory changes alter the conditions from which patterns emerge. A change in activation can reorganise posture, movement, attention and relational behaviour. Conversely, a newly emerging pattern can alter regulatory demands.
A different posture may reduce or increase effort. A new relational response may change emotional activation. More coordinated movement may alter breathing. A clearer boundary may change the intensity required to maintain contact.
Regulation therefore participates within Self-Organisation without directing every detail of what emerges.
Self-Organisation describes how patterns arise and reorganise through interactions among processes. Regulation describes how activity within those interactions is modulated in relation to changing conditions.
Autonomic Regulation
The autonomic nervous system provides an important physiological dimension of Regulation.
Autonomic processes contribute to cardiovascular activity, respiration, digestion, thermoregulation, metabolic mobilisation and many other functions necessary for ongoing life. These processes continually adjust as activity and environmental demands change.
Within psychotherapy and somatic practice, autonomic concepts can help describe aspects of activation, mobilisation, settling and recovery. They can also provide useful hypotheses about changes observed in breathing, colour, temperature, movement, voice or bodily state.
Such observations require caution.
No single visible behaviour reliably identifies a specific autonomic state, and psychological meaning cannot be read directly from autonomic physiology. Similar outward expressions may occur under very different conditions, while complex autonomic processes cannot be reduced to simple categories such as “regulated” and “dysregulated.”
Core Strokes® therefore includes autonomic Regulation within a wider organisational perspective rather than treating it as a complete explanation of embodied experience.
Breath and Regulation
Breathing is both influenced by Regulation and capable of influencing the conditions within which Regulation occurs.
Respiration changes with metabolic demand, posture, movement, speech, emotion, attention and interpersonal engagement. It can change automatically and can also be modified intentionally.
This makes breathing particularly useful clinically because it provides a perceptible interface among processes that are otherwise difficult to observe directly.
The relevant question, however, is not whether breathing conforms to an ideal pattern. Slow breathing is not inherently more regulated than rapid breathing, nor is deep breathing necessarily more appropriate than shallow breathing.
Running, speaking, crying, laughing, resting and concentrating require different respiratory organisations.
Within Core Strokes®, the practitioner therefore observes how breathing changes in relation to the person’s activity and experience. Regulatory significance emerges from these relationships rather than from comparison with a universally preferred respiratory pattern.
Movement and Regulation
Movement provides another major means through which living organisms regulate activity.
A person may approach, withdraw, orient, reach, push, brace, rest, shake, change position or increase muscular effort. These movements alter relationships with the environment while simultaneously changing bodily conditions.
Movement therefore cannot be treated merely as an expression of internal state. It can itself participate in changing the conditions of experience.
Standing may increase possibilities for action. Increasing distance may alter a relational encounter. Pushing against resistance may change muscular recruitment and perception of force. Resting may reduce demands that previously required sustained effort.
Regulation through movement is therefore relational and functional.
Its significance depends upon what the movement accomplishes within the conditions in which it occurs.
Fascia and Regulation
Fascia and connective tissues participate in the mechanical conditions through which posture and movement are organised.
Changes in muscular activity, loading, movement and breathing alter mechanical relationships across connective tissues. Tissue properties influence how forces are distributed and how different bodily regions participate in movement.
Therapeutic touch may provide phenomenological information about tissue responsiveness, resistance, yielding, recoil and changes occurring during contact or movement.
These observations can contribute to understanding embodied Regulation, but they should not be interpreted as direct measurements of regulatory state.
A region that feels firm, soft, resistant or yielding does not by itself reveal whether a person is “regulated,” nor does tactile change establish a particular autonomic, emotional or developmental process.
The Fascia Texture Typology™ provides a disciplined language for describing tactile configurations before their possible organisational significance is considered within the wider context of breathing, movement, sensation and relational participation.
Fascia can therefore provide a perceptual window onto aspects of embodied organisation without becoming a surrogate measure of Regulation.
Emotional Regulation
Emotional Regulation is often understood as reducing intense emotion. Within Core Strokes®, the concept is broader.
Regulation may involve allowing emotional activation to increase sufficiently for experience or expression to become possible. At other times, intensity may need to diminish. An emotion may need to be contained, sustained, expressed, redirected or allowed gradually to change.
The regulatory question is therefore not whether emotion becomes smaller.
It concerns whether emotional activity can change in relation to the conditions in which the person is participating.
This perspective also distinguishes Regulation from suppression. Suppression may sometimes function as a regulatory strategy, but it represents only one possible form of modulation. Expression can likewise be regulatory under some conditions without being inherently healthier.
Flexible emotional Regulation involves a repertoire through which intensity, expression, inhibition and participation can vary rather than a requirement that emotional activation remain low.
Regulation and Relationship
Human Regulation is profoundly relational.
The presence, behaviour and responses of other people can alter attention, breathing, muscular activity, emotion and possibilities for action. A supportive interaction may permit activity to diminish, while conflict may increase mobilisation. Clear boundaries can alter the intensity required to remain engaged.
At the same time, relational influence should not be understood as one person directly regulating another person’s internal state.
Each participant remains a distinct living organisation. One person’s behaviour changes conditions within the relational field, and the other organises in relation to those conditions.
Regulation in relationship is therefore reciprocal without implying fusion.
Each person’s regulatory organisation influences the encounter, while the encounter becomes part of the conditions to which each person responds.
Regulation and Co-Regulation
The term co-regulation is widely used to describe the ways interaction with another person can contribute to changes in activation and regulatory organisation.
Within Core Strokes®, co-regulation can be understood through Participation. Voice, timing, facial expression, proximity, touch, movement, predictability and responsiveness alter the relational conditions in which both participants organise.
This does not mean that one nervous system simply regulates another.
Each participant perceives and responds through their own living organisation. The interaction creates changing conditions that can support settling, mobilisation, orientation, expression, boundary formation or other forms of regulatory change.
Co-regulation is therefore best understood as an emergent relational process rather than the transmission of a regulatory state from one person to another.
Regulation and Relational Geometry
Relational Geometry provides a concrete field for observing how Regulation changes within interaction.
Proximity may increase activation under one condition and support settling under another. Greater distance may permit orientation and choice, or it may increase uncertainty. Turning towards another person may support engagement, while changing orientation may reduce intensity without ending contact.
No particular relational geometry is inherently regulatory.
Its significance depends upon the participants, their histories, the present interaction and the way organisation changes as the geometry changes.
The practitioner can therefore observe how proximity, distance, orientation, boundary, direction, reciprocity, approach and withdrawal relate to changes in breathing, movement, attention, expression and reported experience.
Relational geometry becomes clinically useful not because specific positions have fixed meanings, but because changing spatial conditions can reveal how Regulation is organised within participation.
Regulation and Defensive Organisation
Defensive Organisation frequently involves highly effective Regulation.
Muscular holding can limit movement. Emotional inhibition can contain expression. Hypervigilance can maintain attention to potential danger. Withdrawal can reduce relational demand. Compulsive control can narrow uncertainty.
These patterns may significantly constrain experience, but they should not therefore be described simply as failures of Regulation.
They often represent regulatory solutions developed under particular conditions.
The clinical issue is more precisely whether the available regulatory repertoire remains sufficiently flexible when conditions change. A response that once preserved safety or functioning may continue to organise activity even when other possibilities have become viable.
Therapeutic work therefore does not seek to eliminate defensive Regulation indiscriminately. It explores whether additional regulatory possibilities can become available without removing organisation that continues to serve necessary functions.
Trauma and Regulation
Overwhelming experience can alter the organisation of Regulation.
Under threat, activity may need to change rapidly. Attention can narrow, muscular mobilisation may increase, movement may be inhibited, breathing may alter and relational participation may become organised around protection.
Such responses should not automatically be interpreted as regulatory failure. Under dangerous conditions, rapid mobilisation, withdrawal, immobilisation or narrowed attention may contribute to survival.
Difficulties can arise when a restricted regulatory repertoire becomes repeatedly recruited under conditions that differ from those in which it developed.
Relatively minor cues may then be accompanied by widespread mobilisation, or activation may be rapidly inhibited before broader participation becomes possible.
Therapeutic work can explore whether regulatory possibilities become more differentiated: whether activation can increase without inevitably becoming overwhelming, diminish without collapsing participation, remain present without requiring immediate action, and change direction as present conditions change.
The aim is not permanent calm but a broader repertoire for modulation.
Regulation and Adaptation
Regulation and Adaptation are closely related but distinct.
Regulation concerns the modulation of activity in relation to changing conditions. Adaptation concerns how organisation itself changes in relation to the conditions in which the organism participates.
A regulatory response may be temporary. A person increases muscular effort to lift a heavy object and reduces it afterwards. Attention intensifies during a demanding task and later broadens.
When particular regulatory configurations are repeatedly required, however, they may contribute to more enduring adaptive organisation.
Repeated vigilance, inhibition, mobilisation or withdrawal can become increasingly established patterns through which the organism meets recurring conditions.
Regulation therefore concerns ongoing modulation, while Adaptation concerns the ways organisation becomes shaped through its history of participation.
The distinction will be particularly important when considering enduring protective patterns within Core Strokes®.
The Developmental Organisation of Regulation
Regulation is present from the beginning of life. Development does not proceed from an entirely unregulated organism towards one that eventually acquires Regulation.
Early regulation involves biological processes as well as extensive participation with caregivers and the surrounding environment. Feeding, warmth, movement, touch, voice, rhythm and proximity all contribute to the conditions within which infant activity changes.
Across development, regulatory possibilities can become increasingly differentiated. Movement expands the ability to alter environmental conditions directly. Communication allows needs and boundaries to be expressed in new ways. Increasing Differentiation permits more specific responses, while developing Integration allows a broader range of information to participate in modulation.
Regulation can therefore become less dependent upon a limited set of responses without ever becoming independent of relationship or environment.
Developmental maturity should not be equated with self-regulation understood as complete autonomy. Adults continue to regulate through movement, physical surroundings, social relationships, routines, language, culture and contact with others.
What can develop is a broader and more flexible repertoire through which activity can be increased, decreased, maintained, redirected, contained or interrupted according to changing conditions.
Development therefore involves not simply more Regulation, but greater differentiation and flexibility in how Regulation is organised.
Observing Regulation
Regulation is an Organisational-Dynamic Principle and cannot be directly observed as an abstract process. What becomes perceptible are changes in activity and their relationships with changing conditions.
Observation may include:
- changes in breathing as activity or interaction changes;
- shifts in muscular activity and posture;
- changes in movement speed, range or direction;
- alterations in attention and orientation;
- changes in vocal intensity, rhythm or timing;
- how emotional activation increases, decreases or remains sustained;
- whether activity remains local or becomes more widespread;
- how a participant responds when intensity increases;
- how boundaries or relational distance alter activity;
- whether organisation can change when environmental or relational conditions change.
No single observation establishes whether Regulation is flexible or constrained.
Quietness does not necessarily indicate effective Regulation, just as intense activation does not necessarily indicate dysregulation.
Interpretation requires attention to context, timing, recurrence, participant experience and the relationship among multiple observations.
Within Core Strokes®, description therefore precedes organisational interpretation.
The Living Participation Observation System™ (LPOS™) provides a structured phenomenological framework for describing such changes before provisional organisational interpretations are developed.
Regulation and Therapeutic Touch
Therapeutic touch changes sensory, mechanical and relational conditions and can therefore participate in Regulation.
Contact may be accompanied by changes in breathing, muscular activity, movement, attention, sensation or emotional experience. Activity may diminish, increase, become more localised or reorganise in another direction.
None of these outcomes should automatically be considered preferable.
Touch that increases activation may support orientation, boundary awareness or movement. Touch that contributes to settling may permit rest or broader perception. At other times, maintaining the existing level of activation may be more appropriate than attempting to change it.
The practitioner therefore does not use touch simply to calm the nervous system.
Instead, touch becomes one possible form of therapeutic participation through which changing organisation can be observed and, where clinically appropriate, influenced.
The significance of the response depends upon the participant, the therapeutic context and what becomes possible within the wider organisation.
Regulation and Therapeutic Transformation
Therapeutic transformation often involves changes in the repertoire through which activity can be regulated.
A person who habitually suppresses activation may become able to tolerate stronger movement, emotion or expression. Someone whose activation rapidly becomes widespread may develop greater possibilities for maintaining local experience without global mobilisation. A person who withdraws when relational intensity increases may become able to remain engaged while adjusting distance, boundaries or expression.
These changes should not be understood as movement towards one preferred regulatory state.
They represent an expansion of possible organisation.
Therapy can participate by altering conditions, supporting perception, inviting movement, clarifying boundaries, providing relational responsiveness and allowing established regulatory strategies to become perceptible.
The practitioner does not regulate the participant into an ideal state. Practitioner and participant explore how activity changes and whether additional forms of modulation can become available.
Therapeutic transformation therefore involves not the elimination of activation or defensive Regulation, but a broader capacity for activity to change in relation to present conditions.

Final Orientation
Within Core Strokes®, Regulation describes how living activity is modulated as conditions change.
It does not designate a preferred state.
Living organisms need to rest and mobilise, approach and withdraw, sustain activity and interrupt it, express and contain, intensify and settle. Each of these possibilities can participate within Regulation.
The relevant question is therefore not whether activation is high or low, whether a person appears calm, or whether a particular physiological state has been achieved.
What matters is how activity changes in relation to what the organism is encountering and how broad a repertoire remains available when conditions change.
Protective Regulation may sometimes narrow that repertoire while preserving essential Continuity. Therapeutic work does not need to oppose such organisation. It can explore whether additional possibilities become available without removing the functions that established regulatory patterns continue to serve.
Regulation is not the maintenance of calm. It is the capacity of living organisation to modulate activity in relation to changing conditions.
