Primitive reflexes (PRs) are foundational components of the human nervous system, serving as essential building blocks for complex motor and cognitive functions. These automatic, involuntary movements are present at birth and typically integrate as the child matures, usually by the age of two. Controlled by cranial nerves in the brainstem—a primitive part of the brain—these reflexes maintain a balance between the parasympathetic and sympathetic nervous systems, supporting motor movement, decision-making, and emotional regulation. When these reflexes remain reactive or reemerge later in life, they disrupt vagal nerve signals, leaving the body in a heightened state of arousal, and flooding the brain with stress hormones along the HPA axis.
Proper integration
of primitive reflexes is essential for developing higher-order skills,
including decision-making, emotional regulation, and maintaining balance within
the autonomic nervous system. Incomplete integration or reactivation of these
reflexes leads to challenges such as poor coordination, orthopedic issues,
learning difficulties, and behavioral problems. Trauma—whether emotional or
physical, such as emotional shock, head injuries, car accidents, or neurogenic
disease—reactivates these reflexes in both children and adults, indicating
chronic states of high sympathetic arousal. This heightened state impacts the
patient's overall health and well-being, even if they do not perceive it as
emotional stress.
In children with
adverse childhood experiences (ACEs) scores higher than 3, these reflexes fail
to integrate. Children in sympathetically charged or dangerous environments
remain locked in a freeze state, preventing proper reflex integration. When one
reflex fails to integrate, it disrupts the development of several higher-order
reflexes, leading to compounded developmental deficits that persist into
adulthood.
The reactivation of
PRs in adults—whether due to PTSD, traumatic brain injury (TBI), stroke, or
demyelinating diseases—indicates both the involvement of cranial nerves and a
body in a chronic state of high arousal. This state of sympathetic dominance,
or retained fight-flight-freeze response, impairs the body’s ability to engage
in neuroplasticity—a process essential for recovery and adaptation. PR
demonstration in adults serves as a clear marker for clinicians to assess the
underlying autonomic dysfunction that hinders healing.
Svetlana Masgutova’s
work has significantly advanced our understanding of these primitive reflexes,
particularly in how they reemerge in response to trauma. Masgutova identified
over 30 primary reflex patterns that are fundamental to our neurodevelopment.
Trauma reactivates these reflexes in adults, contributing to chronic stress,
anxiety, and other maladaptive behaviors. Her findings provide a clear
understanding of the pathomechanisms involved, illustrating how a reactivated
PR keeps the body in a state of high arousal, preventing neuroplasticity and
natural healing processes.
While Masgutova's
MNRI (Masgutova Neurosensorimotor Reflex Integration) method is effective in
children, it does not, however, yield the same results in adults, especially those with
long-term conditions. The MNRI method, which draws from occupational therapy
(OT) and physical therapy (PT) techniques, works well in children but fails to
address the needs of adults whose reflexes did not integrate properly. The adult body has a more rigid bony matrix with higher levels of chondroitin. The reflex integration exercises provide no healing or balance to the nervous system in adults with neurogenic diseases or
conditions involving spasticity including nystagmus.
As a healthcare
provider, neuroscience student, and neuro-trauma patient, I found myself in a
unique position to both understand and explore these issues. Like Dr. Jill
Bolte Taylor, who chronicled her journey of neuroplasticity after a stroke, I
navigated through life-threatening
neurological disease with self-awareness, drawing on the
profound insights provided by experts like Masgutova, Peter Levine, and PVT. MNRI provided a foundational understanding of the pathomechanisms behind the derangement in both
my own nervous system and that of my clients, but it was Traditional
Chinese Medicine (TCM) that emerged as the clinical method for restoring
parasympathetic balance to the ANS to harness neuroplasticity.
To date, there has been no existing treatment that fully restores parasympathetic balance to the autonomic nervous system, particularly for conditions like Parkinson’s, MS, and PTSD. My neuro patients understood this reality as well, and together, we have created a new approach. A neuro-informed approach to TCM allows us to restore balance to the ANS visibly by working with the sinew channels.
This approach not
only addressed the physiological impacts of reactivated PRs but also provided a
tangible method for observing and enhancing autonomic function. Ultimately,
this method promotes neuroplasticity and provides illumination for many issues
observed in chronic neurogenic disease and trauma. These techniques are not
limited to TCM practitioners, however. They can be effectively employed by
professionals across various disciplines, including massage therapists,
physical therapists, and medical doctors. Working hand in hand with my clients, we continue to
discover simpler ways for patients to support their parasympathetic baseline
more effectively, empowering them to take an active role in their own healing.
