RETAINED PRIMITIVE REFLEXES
Their Effect on Learning, Behavior and Quality of Life
Structural Corrections That Assist Their Integration
Written by:Keith Keen, Sydney , Australia
The Problem
It has been estimated that 15-20% of children in our society suffer some degree of learning difficulty. “Learning Difficulty” in this paper refers to those who perform poor academically in the absence of intellectual or gross physical impairment.
We all agree that any form of learning difficulty is worthy of attention, so the child (or adult) has the opportunity to reach full potential and enjoy life as fully as possible.
But the consequences of learning difficulty can be far more far reaching and disturbing than many of us realize.
In studies of recidivism (those who break the law and continue to do so despite being caught and punished), a very large percentage suffer from learning difficulty.
Juvenile suicide is an increasing and disturbing phenomenon. The Attention Deficit Hyperactive Disorder (ADHD) population has an attempt rate far higher than the normal population, about half of whom succeed.
Children presenting with learning difficulty have a higher incidence of the symptoms of depression and anxiety.
So learning difficulty and behavior disorder is not just stopping our children from succeeding at school, it is filling our goals
it is crippling the future of our society
The Solution
On the bright side -a large proportion of those suffering from learning difficulty can be, and have been helped.
But about 15% of students do not learn easily despite excellent teaching, parenting and individual tutoring. That’s quite a large percent considering the possible consequences.
It is obvious that, if teaching, parenting and individual tutoring are not succeeding; we have to look somewhere else.
Over the last decade and a half we have found that the problem appears to be in the physiological, neurological and biochemical systems of the body that together provide the basis for the complex skills that are required for learning and behavior.
Retained primitive reflexes are a major problem that disrupts the physiological, neurological and biochemical bases of learning and behavior.
Primitive Reflexes
Our Central Nervous System is our Control Centre for Living. It is essential for perceiving the world around us, for moving around and doing things in it; for thinking, feeling, learning, communicating, working, playing, loving, surviving.
Anatomically, the central nervous system is composed of the brain and spinal cord. The brain may be divided into a hierarchy of centers:
1) the most evolved thinking and integrating part, the cerebral cortex at the top
2) the older brain of instinct and housekeeping in the middle
3) the oldest , the brainstem, just above the spinal cord
Of course these "centers" are not isolated, they are quite complexly interlinked, but separating them helps to understand brain processes.
"Primitive" means "earliest of its kind" as the nerve centers controlling primitive reflexes are in the oldest (most primitive) part of the brain, the brainstem.
In the womb and in early months of life the higher centers of our central nervous system are not fully developed. During this time we are protected and assisted by reflexes, controlled by lower centers of our brain. A reflex does not involve thinking, it is an involuntary response. That is: given an external stimulus (e.g. touch, noise, heat) or internal stimulus (e.g. hunger) there is an automatic, involuntary reaction if the relevant reflex is active. Reflex response varies from simple muscular movement (e.g. moving a body part away from pain) to quite complex reflexes involving body movements, breathing, perceptual and hormonal changes.
Primitive reflexes are needed for survival and development in the womb and in early months of life. As higher centers begin to mature enough for conscious control of activity, the involuntary, uncontrollable reflex responses are a nuisance. The reflexes anatomically and neurologically stay for the remainder of our life, but, if all is well, they are integrated into higher centre control.
Retained Primitive Reflexes
Primitive reflexes ideally begin to function in a particular order and are integrated in a specific sequence. If they are retained out of sequence, they disturb the development and integration of subsequent reflexes. If they are retained beyond their normal age of integration they can disturb some or all of the functions of higher centers, which includes behavior, learning, the integration of gross or fine movements and more.
Basically, the perception of our inner and outer environment and our response to it may be disturbed;
that is, conscious life may be disturbed.
Causality Like all questions on the nature of life and health there are no absolute answers on causality. It appears that trauma of some kind is involved somewhere between conception and early months of life. The trauma can be physical, chemical, and hormonal or other forms not yet researched. In utero many chemicals and hormones can pass through the umbilical cord; all manner of traumatic events can occur in the delicate early months of life; but the big one appears to be birth trauma. (I include caesarean section as trauma). Statistics and clinical observation show that there may be genetic factors. These appear to be predispositions that raise the probability of problems arising from trauma.
Consequences of Retained Primitive Reflexes
Fear Paralysis Reflex
If this reflex is retained after birth, it can be characterized by withdrawal, reticence at being involved in anything new, fear of different circumstances, the child who bears the brunt of teasing by normally adventurous children.
Inappropriate retention of the fear paralysis reflex can contribute to such conditions as Sudden Infant Death Syndrome, elective mutism, hypersensitivity to sensory information and may result in physical and psychological conditions such as Panic Disorders. As it begins first and is normally integrated first, retained fear paralysis reflex may effect the integration of any other primitive reflex.
Moro Reflex
The reflex is set off by excessive information in any of the baby's senses. A loud noise, bright light, sudden rough touch, sudden dropping or tilting, turns on this "one reflex suits all" reflex. The reflex has to cover all eventualities so the child's sympathetic hormonal and neurological response is elicited, preparing the child's body for whatever turned on its alarm system.
If the Moro reflex persists beyond three to six months of age it becomes an automatic therefore uncontrollable overreaction, overriding the newly acquired higher centre decision making. The child (or adult) may be hypersensitive to any of the senses and so may withdraw from situations, or, as it stimulates sympathetic fight or flight responses, the person may be an aggressive, over reactive, highly excitable, and unable to turn off and relax.
Those with retained Moro may be very difficult to understand, they may be loving, perceptive and imaginative but at the same time immature, over reactive and aggressive.
As an adrenal response may be inappropriately elicited many times a day and is on standby most of the time, there is a constant demand on the adrenal glands which may become fatigued, thus leading to hypoadrenic symptoms such as allergy, asthma or chronic illness.
Asymmetrical Tonic Neck Reflex (ATNR)
In the first months of life, while the ATNR is operating, the hand moves in conjunction with the head. This connection between touch and vision helps to establish distance perception and hand eye coordination. By the middle of the first year of life this is normally accomplished and the ATNR, being no longer required, should be integrated.
With retained ATNR, difficulty may be experienced with tasks that involve both left and right sides of the body (including eyes, ears, limbs etc).
Turning the head may cause a visual image to momentarily disappear or parts of the visual field to be missed. Visual tracking and judgment of distance may be affected.
Each time the head is turned the arm wants to follow it and the fingers want to open. Writing therefore requires enormous effort to hold the hand still while the head is doing different things like looking up at a blackboard.
To compensate for this, excessive writing pressure often occurs and/or a clenched fist pencil grip, both of which affect quality and quantity of writing. The act of writing requires intense concentration at the expense of thinking about what is being written, thus they may be fluent of speech but unable to express ideas in written form.
Adults who suffer recurrent shoulder injury or neck stiffness, especially if always on the same side, often have a unilaterally retained ATNR. It appears that in the presence of some degree of retained ATNR, their hand and eye are not fully neurologically (therefore functionally) independent. This is a constant stress, interrupting the fine organization required for smooth head, eye, arm, and hand coordination, which leads to structural problems, as well as affecting sports performance.
Tonic Labyrinthine Reflex (TLR)
If the tonic labyrinthine reflex is not integrated at the correct time it will constantly disturb the labyrinthine (balance) system.
Head-righting reflexes and therefore visual function may be impaired. The person may experience difficulty in judging space, distance, depth and speed. Susceptibility to motion sickness is common with retained Tonic Labyrinthine Reflex
When the sagittal (front to back) component of the tonic labyrinthine reflex is retained, flexion of the head for more than 6-10 seconds (as in working at a desk or reading) causes neurological disorganization. Thus the child (or adult) loses attention soon after taking this position. Needless to say this appears as attention deficit and is deleterious to studying or working, but is secondary to a correctable cranial fault.
Spinal Galant Reflex
In the newborn, stroking the low back to one side of the spine will result in a twisting away from that side, with a rising of the hip on the same side. Stimulation down both sides of the spine simultaneously activates a related reflex, which elicits urination.
If the spinal galant is retained beyond normal time of integration it may be elicited at any time by light pressure in the low back region. In the classroom, the child's belt or waistband or leaning against the back of a chair may activate the reflex, creating the 'ants in the pants' child who wriggles, squirms and constantly changes body position. This constant irritant affects concentration and short-term memory (as well as getting them into trouble).
Due to the neurological association with a bladder voiding reflex, children with retained spinal galant reflex may have poor bladder control. As the low back region is stimulated by bed sheets, the involuntary voiding reflex may be elicited. Thus the child may continue to wet the bed despite all attempts to stop.
When retained, this reflex may affect posture and walking gait, contribute to spinal scoliosis, and affect fluency and mobility of movement.
Juvenile Suck Reflex
The newborn projects the tongue forwards to suck a nipple.
In the adult swallow reflex, the tongue moves backwards to push food down the throat.
If a juvenile suck reflex is retained, the tongue projects forwards before moving backward in the normal swallow.
This tongue thrust continually pushes the front teeth forwards, altering the shape of the upper teeth towards a class 2 bite. It is a huge problem for dentists (and their patients).
Palmar and Plantar Reflexes
The palmar and plantar reflexes are part of the group of reflexes which develop in utero, and whose common characteristic is to grasp.
Retention may cause poor manual dexterity and /or pencil grip due to reduced independence of thumb and finger movement.
Speech difficulties due to a continuing relationship between hand and mouth movement.
Mouth movements when trying to write or draw.
Structural Corrections for Retained Primitive Reflexes
The good news is: We can greatly assist the integration of retained primitive reflexes with specialized craniosacral correction.
The Central Nervous System is so important as a Control Centre that it is housed in a membrane that isolates it from the rest of the body. Outside that membrane, blood supplies nutrition and lymph carries wastage. Inside the membrane, a clear fluid called cerebrospinal fluid provides nutrition and protection to the central nervous system.
The outer membrane surrounding the Central Nervous System is called the Dura Mater. It attaches at its uppermost end to the inside of our skull; it surrounds our brain, brainstem and spinal cord, and attaches at its lowermost end to our tailbone. Cerebrospinal fluid is circulated mainly by the rhythmic movement of our cranial (skull) bones at the top and the movement of our sacrum (in the middle rear of our pelvis) at the bottom, joined by the dura mater between. If this craniosacral system is not functioning correctly, many symptoms can occur. Basically, as the central nervous system is involved, almost anything can not function at its best. Headaches, muscular imbalance, hormonal dysfunction, developmental delay (including retained primitive reflexes) and learning disability are common problems.
Cranial or sacral correction is mostly gentle pressure on a particular place or places (on the skull or pelvis) in a specific direction, often on a specific phase of breathing. This helps to restore normal membrane to bone relationship and craniosacral movement. As it is the craniosacral movement which circulates cerebrospinal fluid, its correction helps to normalize central nervous system function.
A decade or so ago I discovered that some craniosacral faults may be found only in body postures related to primitive reflexes. Furthermore it appears that these craniosacral problems inhibit normal integration of the reflex. Correction of craniosacral faults while in those postures removes the inhibition to normal primitive reflex integration. Higher centers may then integrate the reflexes. These postural craniosacral faults usually stay corrected, needing no further structural intervention.
Research
In 1998 I performed a retrospective statistical analysis on a group of children tested behaviorally for retention of primitive reflexes by a neurodevelopmental assessor before and after the corrections discussed in this paper. No other intervention took place between pre and post testing.
The results of this pilot study support what we have observed clinically for a decade, returning positive changes at probabilities ranging from p<.05 to p<.01 (Keen, 1999).
In the February 2000 edition of The Lancet, a randomized, double blind, controlled trial indicates that there is a significant relationship between retained primitive reflexes and learning difficulty (McPhillips et al, 2000); a relationship well known in clinical practice.
The conclusion states:
"This study demonstrates the importance of assessing underlying neurodevelopmental functioning and, in particular, the persistence of primary [primitive] reflexes when considering the basis of learning difficulties."
The McPhillips et al study used only one reflex (ATNR) and for correction only movement exercises.
Imagine the positive changes when we apply procedures that have proven to be much more effective, and apply it to many primitive reflexes.
Brainstem Injury
Earlier this year a patient presented after having fallen 50 feet onto his head (and survived). After his one month coma he was left with a few problems, including a moderate left hemiplegia. Magnetic resonance imaging (MRI) indicated trauma to his brainstem.
Four months after the accident he presented to my clinic. Most of his symptoms responded excellently to standard structural corrections, but some left hemiplegia remained.
When all standard indicators were clear, I applied the diagnostic tests for retained primitive reflexes. Two were positive, despite his having no history of the symptoms of primitive reflex retention in his earlier life. Remembering that his MRI indicated brainstem trauma, I applied the corrections indicated. His left hemiplegia reduced dramatically.
Interaction with Other Professions
A retained primitive reflex is by definition developmental delay. It must be emphasized that developmental delay and learning difficulty are multifactorial problems. Structural correction is only one factor of many. Structural correction can be likened to fixing the "hardware" of a computer. It does not necessarily mean that the person then functions perfectly, for there is also the "software" to consider. Thus structural correction is only one therapy in a team which may include: Behavioral Optometrists, Educationalists, Medical Practitioners, Neurodevelopmental Assessors, Neurofeedback Therapists, Nutritionists, Occupational Therapists, Psychologists, Reflex Movement Therapists, Sound Therapists, Speech Therapists, etc. (Note that this list is alphabetical and indicates neither order nor importance of therapy).
Other professionals with whom we interactively refer report that their therapy and their results are greatly enhanced if retained primitive reflexes are treated first.
Conclusion
Structural, mostly craniosacral, corrections have been developed that assist the integration of retained primitive reflexes, assist many aspects of learning difficulty, reveal other hidden structural problems, reduce the symptoms of brainstem injury and facilitate other therapies.
Primitive reflexes are automatic, stimulus-elicited without involvement of our higher decision making processes. The child (or adult) has little or no control over their elicitation. There is little use trying to force extra teaching or behavior modification upon a system in which the basic intrinsic modules for learning and behavior are not correctly functioning.
Best treat where the problem resides. That is, at an intrinsic functional level.
To assist retained primitive reflexes to integrate is to optimize human potential at very deep level and in a far-reaching and highly effectively way.
