Primitive reflexes are a set of programmes in the brain which are present in all humans for survival. They are integrated and switched off when an infant starts to have conscious control of his/her movements. They have a limited time span and are switched off or integrated through normal childhood activities. If the reflexes are retained they can lead to neuro-developmental delay and poor sensory integration e.g. they can impair balance which will cause a child difficulty in judging space, distance, depth and speed. Balance is vital for everyone, for example, when astronauts lose their sense of balance in space they start to write from right to left, reverse numbers and letters and produce mirror writing. The following reflexes are the ones that are most often retained.
Fear Paralysis reflex
MORO REFLEX
ROOTING REFLEX
SUCK REFLEX
ASYMMETRICAL TONIC
NECK REFLEX
PALMAR REFLEX AND
PLANTAR REFLEX
SPINAL GALANT REFLEX
TONIC LABYRINTHINE REFLEX
SYMMETRICAL TONIC
NECK REFLEX
The Fear Paralysis begins to function very early after conception and should normally be integrated before birth. It can be characterised by withdrawal, reluctance at being involved in anything new, fear of different circumstances, clinginess, timidity etc.
The Fear Paralysis Reflex may present in any of the following symptoms;
Anxiety and low stress tolerance
Temper tantrums
Increased sensory sensitivity
Inability to cope with any change
Breath holding
Insecure and overly clingy
Obsessive traits
Stress paralysis, can’t think and move simultaneous
Sleep issues
This reflex holds the child in a flight and fight response. The reflex has to cover all eventualities so the child’s sympathetic hormonal and neurological response is activated, preparing the body to protect itself. It is the reflex that allows the body to take the first breath of life automatically.
The Moro Reflex should be integrated between 4 – 5 months and my present as any of the following symptoms;
Hyperactivity;
Extreme sensitivity to sudden movement, noise or light
Difficulty getting to or staying asleep
Impulsive or distractive behaviour
Inappropriate response to a situation
Food sensitivities
Emotional and social immaturity
Unable to relax
This reflex is there in preparation for suckling. The combination of rooting and suck reflexes ensures that a baby’s head turns toward a source of food and the mouth opens wide enough to accommodate a nipple.
The Rooting Reflex should be integrated between 3 – 4 months, retention may present as any of the following symptoms;
Increased sensitivity around the lips and mouth
Speech and articulation problems
Dribbling, difficulty swallowing and chewing
They may be fussy eaters, particularly with texture and are often thumb suckers
Poor manual dexterity
If a Suck Reflex is not adequately integrated, the tongue projects forwards before moving backward in the normal swallow action. This tongue thrust continually pushes the front teeth forwards, altering the shape of the maxillary arch.
The Suck Reflex should be integrated between 3 – 4 months, retention may present as any of the following symptoms;
Speech delay
Articulation and pronunciation difficulties
Swallowing and chewing problems
Overbite of the upper jaw
Involuntary tongue movements when writing or drawing
A lisp
Problems with breast feeding
The reflex continues after birth and plays an important part in the development of hand eye coordination, object and distance perception.
If the ATNR is retained, difficulty may be experienced with tasks which involve both left and right sides of the body including eyes, ears, limbs etc. Establishment of dominant hand, foot, ear or eye may be difficult. Turning the head may cause a visual image to momentarily disappear or parts of the visual field to be missed. Visual tracking and judgement of distance may be therefore be affected.
The Asymmetrical Tonic Neck Reflex should be integrated between 6 – 7 months, retention may present as any of the following symptoms;
Difficulty catching a ball
Poor handwriting, abnormal pencil grip
Handwriting problems, does not like cursive writing
Difficulty establishing right and left body dominance
Poor distance judgement
Shoulder and neck problems
Palmar and PlantarreflexThe Palmar Reflex and the Plantar reflex should integrate at about the same time, between 4 – 6 months. The Palmar and Plantar reflexes are part of a group of reflexes that develop in the uterus and whose common characteristic is to grasp.
Palmar and PlantarreflexThe Palmar and Plantar reflexes should be integrated between 5 – 6 months, retention may present as any of the following symptoms;
Poor fine motor skills;
Poor pen-grip and handwriting;
Slumped posture when writing or working over desk;
Doesn’t enjoy writing;
Poor spelling.
Balance and walking is affected
Delayed walking beyond 14 months
Awkward running style and poor balance
Toes curl under when putting on shoes;
This reflexes wriggling motion appears to take an active role in the birth process, with movements of the hip helping the baby to work its way down the birth canal.
The Spinal Galant Reflex should be integrated between 12 – 13 months, retention may present as any of the following symptoms:
Inability to sit still
Attention and concentration problems
Bedwetting and poor bladder control
Clumsiness, often falling over
Possible development of scoliosis
Irritated by tight waistbands around this area or tucking shirt in
May have auditory processing issues
This reflexes wriggling motion appears to take an active role in the birth process, with movements of the hip helping the baby to work its way down the birth canal.
The Tonic Labyrinthine Reflex may present itself in the following:
Poor balance and co ordination
Motion sickness
Orientation difficulties, judging space, distance and depth
Auditory processing difficulties
Slouchy tension in body
Dislike of heights and fairground rides
The STNR is helps the baby with the action of crawling and to start tracking, as well as establishing contralateral movement.
The Symmetrical Tonic Neck Reflex should be integrated between 12 – 13 months, and may present as any of the following symptoms;
Crawling in unusual ways
Poor hand – eye co-ordination
Walking on toes
Odd pattern of walking
Slumping at desk
Constant eye fatigue
Poor organisation skills
Problems in pregnancy.
Problems in delivery.
Problems with birthing
(forceps, suction, C-section, induction, long, short).
Difficulty in feeding or keeping milk down.
Early or late walking – before 10 months or after 16 months.
Unusual crawling action or skip the cross crawling stage.
Late when learning to talk (2-3 words by 2 years).
Serious illness or seizures in the first 18 months of life.
Signs of eczema, asthma or allergies or recurrent sinus or ear
infections or headaches.
Adverse reactions to childhood vaccinations.
Bed wetting regularly past the age of 5.
Thumb sucking past the age of 5.
Problems with travel / motion sickness.
Trouble establishing hand dominance or crossing the midline
with objects.
Over reaction to sudden loud noise.
1Problems learning to read and / or write in the early years
at school
2Difficulty telling the time on an analogue clock.
3Difficulty riding a bicycle.
4Difficulty catching a ball and poor coordination.
5Problems being still.
Problems when copying from the board.
7Occasionally miss letters or write them backwards or missing
words out when reading.
8Awkward pencil grip.
9Behavioural problems at school or problems with going
to school.
10Problems making friends.
If you have answered yes to some or all of these questions then it is likely that there are some retained reflexes causing problems as they are a sign of an immature central nervous system. The child Centre Method can provide assessment and treatment.
