NEUROPLASTICITY
■ Neural connections are either made or dissolved depending on the stimulation received
■ Hebb’s Axiom – what wires together fires together
■ Dr. Norman Doidge
■ Dr. Michael Merzenich
■ Dr. Paul Bach y Rita – activity dependent neuroplasticity
3
ACTIVITY-DEPENDENT PLASTICITY
■ During engagement in activity,
■ signaling molecules (ex: dopamine, glutamate)
■ facilitate synapsing (excitatory or inhibitory)
■ which alters gene expression and allows the brain to rewire itself.
NEURO - PLASTICITY AND THERAPY
■ Analyze movement to determine foundational skill levels
■ Engage in movement to achieve activity dependent plasticity
■ Activity dependent plasticity maximizes a child’s potential in function and activities of daily living
THEORETICAL FRAMEWORKS SUPPORTING PRIMITIVE REFLEX
INTEGRATION THEORY

THEORIES
■ Rood Approach
■ NDT/Bobath: Neuro-Developmental Treatment/Bobath
■ PNF: Proprioceptive Neuromuscular Facilitation
■ Brunnstrom Approach
ROOD APPROACH
■ Theoretically based on the Reflex and Hierarchical Model of Motor Control and provides the origins for many of the facilitation techniques used today
■ Focuses on sensory stimulation and ontogenetic motor development (normal progression of motor skills along the developmental continuum)
■ Cutaneous stimulation – light touch, brushing
■ Proprioceptive stimulation – heavy joint compression, quick stretch, tapping, vestibular stimulation, vibration, neutral warmth, light joint compression
■ Reflexes are used to influence muscle tone and facilitate typical movement patterns
NDT/BOBATH■ “NDT is a holistic and interdisciplinary clinical practice
model informed by current and evolving research that emphasizes individualized therapeutic handling based on movement analysis for habilitation and rehabilitation of individuals with neurological pathophysiology. An in-depth knowledge of the human movement system, including the understanding of typical and atypical development, and expertise in analyzing postural control, movement, activity, and participation throughout the lifespan, form the basis for examination, evaluation, and intervention. Therapeutic handling, used during evaluation and intervention, consists of a dynamic reciprocal interaction between the client and therapist for activating optimal sensorimotor processing, task performance, and skill acquisition to enable participation in meaningful activities.”

NDT/BOBATH
■ Re-learning normal movement patterns with a focus on the quality of movement
■ Focuses on alignment and symmetry
■ Focuses on mastering forward flexion with rotation in order to break up extensor tonal patterns
■ Focuses on weight shift using our own natural body forces
■ Every point of mobility has a point of stability
PNF
■ Focuses on movement patterns that are diagonal and resemble typical movement
■ Focuses on the developing sequence of movement and how the agonist and antagonist muscles work together to produce volitional movement
■ Uses reflexive movement as a basis for learning more volitional movement following the theory that a child must be able to roll before he can crawl and crawl before he walks
■ Uses a multi-sensory approach incorporating tactile, auditory, and visual systems.
BRUNNSTROM APPROACH■ The basic premise is that in typical development,
spinal cord and brain stem reflexes become modified during development, and their components are rearranged into purposeful movement by the influence of higher centers. Since reflexes represent normal stages of development, they can be used when the central nervous system has reverted to an earlier developmental stage
■ Reflexes should be used to elicit movement when none exists (normal developmental sequence)
■ Proprioceptive and exteroceptive stimuli can be used therapeutically to evoke desire motion or tonal change.

■ Provides history of research on primitive reflexes
■ “In 64% of cases it is noticed that children overwhelm to unexpected noises, this opens up the opportunity for the primitive retained reflex, Moro.”
■ “In 64% of cases, mothers noted that the child holds a pencil in a strange manner -this indicates the presence of the primitive Palmar and Suckling reflex”
■ “In 36% of cases, the child makes multiple mistakes when copying from the board. This is indicative of the presence of unbridled primitive reflexes, STNR and ATNR.”
■ “In 79% of cases children have had problems with reading and writing.”
■ “86% have had difficulty tying shoelaces or dressing themselves; showing the presence of the Palmar and suckling reflexes”
“ A. J. Ayres, in her theory of sensory integration, paid attention as well to the selected primitive reflexes, which, in accordance with her opinion, may disturb development, but do not produce symptoms as strong as in spastic diplegia. For that very reason, they may be less intensified.”
“…primary reflexes and postural reflexes develop also such mental functions as: lateralization, visual perception, aural perception and the coordination of them, exerting influence upon emotional development.”
“In school-age children with learning difficulties, primitive reflexes occur in their vestigial form. Those reflexes do not decrease simultaneously with the passage of time, and it rather seems that they have become more intensified”

“The data indicated that, in early infancy, an absent Moro or plantar grasp response may be predictive for adverse developmental outcome. After early infancy, persistence of the Moro response and asymmetric tonic neck reflex was clinically significant. Prediction of a delayed emergence of the parachute reaction increases with age. Abnormal performances on the pull-to-sit maneuver and vertical suspension test have predictive significance throughout infancy. ”

WHAT ARE PRIMITIVE REFLEXES?
9
Innate, typical, and involuntary movement
patterns
Teach developmental sequence of movement
The body learns through the
experience the movement provides
The child acquires higher level motor skills, which, in turn, support higher level
executive functioning skills
A given reflex opens and activates the neural
pathways, conducting the impulse to the different
structures in the brain – in other words, it facilitates
activity dependent plasticity
WE KNOW THAT THEY EXIST
WHERE DO THEY GO?
MEDICAL PROFESSIONALS EVALUATE….
CHECK THEM OFF….…..and then?
10
TYPICAL DEVELOPMENT
Primitive reflexes facilitate movement and engagement in the environment
Activity dependent plasticity (primitive reflex movement patterns) establishes mature neural connections
Promotes integration of primitive reflexes at the appropriate ages -rewires/fine tunes neural pathways and movement patterns
When that does not
happen….
REFLEXES ASSOCIATED WITH
HEAD CONTROL AND DISASSOCIATION OF HEAD FROM BODY
11
Hands Pulling Reflex
Tonic Labrynthine Reflex
Symmetric Tonic Neck Reflex
Assymetric Tonic Neck Reflex
HANDS PULLING REFLEX
HANDS PULLING REFLEX
• Symmetrical Firing• Elbow flexors• Shoulder flexors• Scapula Protraction• Neck Flexors• Abdominal Flexors• Knee Flexion
12
HANDS PULLING REFLEX
• Poor co-contraction – unstable shoulder girdle and extended arms
• No neck flexion/head lag• Chin Retraction• Extension T4-T8• Pelvic extension• Hip/knee extension
EFFECTS OF NON-INTEGRATION
■ Poor muscle tone
■ Poor hand-mouth and hand-eye coordination
■ Delayed manual skills – tool use
■ Poor head righting and ocular motor skills
■ Impact on integration of Moro, TLR, STNR, ATNR
13
TONIC LABRYNTHINE REFLEX
TONIC LABYRINTHINE REFLEXES
Labyrinth of inner ear responds to movement
Head extension brings about extension of the back, arms and legs
Head flexion brings about flexion of the back, arms and legs
Balances the relationship between agonist and protagonist muscle groups
TONIC LABYRINTHINE REFLEX
TLR forward: Develops at 12
weeks in utero Integrates
around four months
14
TONIC LABYRINTHINE REFLEX
TLR backward: Develops at the
time of delivery Integrates
gradually within 7 weeks through 3.5 years old
DEVELOPMENTAL IMPLICATIONS
Muscle tone
Formation of antigravity and stability mechanisms
Integration of vestibular and visual systems: stable head position – strong neck musculature – stable ocular motor mechanisms
Delays progress of integration of additional reflexes – Moro, Landau, STNR
EFFECTS OF NON-INTEGRATION
Poor posture Low muscle tone Poor ocular motor control Poor body awareness and
perception: difficulty judging space, distance, depth, and velocity
Difficulty with head and leg coordination
Walk, run, or jump with jerky or stiff movements – if extensors dominate
Possible challenges with stairs/escalators
Motion sickness Poor sense of time,
sequencing, and organizational skills
15
TLR: ERECT TEST
Stand with feet together Arms down at sides Ask child to look forward,
hold; then tilt head back into extension; hold.
Repeat at comfortable rate 3-4 times
Repeat with eyes closed
TLR: ERECT TEST
Observe posture Amount of neck
extension Increased lordosis Shoulders forward Loss of balance Change in muscle tone
at back of the knees Gripping with the toes Dizziness or nausea
16
SYMMETRICAL TONIC NECK REFLEX (STNR)
SYMMETRICAL TONIC NECK REFLEX
■ Emerges 5-8 months
■ Inhibited 9-11 months
■ While on all fours:■ Neck extension results in UE
extension and LE flexion■ Neck flexion results in UE flexion
and LE extension
DEVELOPMENTAL IMPLICATIONS
Purpose: precursor to crawling Supports integration of TLR Supports distribution of muscle tone in upper and lower
halves of the body Coordination of head with hands, arms, and upper back Disassociation of upper and lower body Allows child to sustain quadruped and rock back and forth Start of accommodative function – expands peripheral and
distance vision
17
EFFECTS OF NON-INTEGRATION
Child does not crawl, bottom shuffles, or crawls with poor quality
Poor posture Slumping in desk Clumsiness Poor visual accommodation Poor eye-hand coordination Academic issues: reading, writing, art, music
EFFECTS OF NON-INTEGRATION
■ Difficulty with bilateral movements – if one hand works, the other helps by moving too
■ Difficulty with copying tasks■ Problems with attention and
concentration■ W-sitter■ Social issues – frustration;
avoidance
STNR - TESTING
■ Position in quadruped■ Ask child to slowly move head to
look down “between your legs”■ Hold 5 seconds■ Slowly move head upwards “as if
looking at the ceiling”■ Repeat up to 6 times

ASYMMETRIC TONIC NECK REFLEX
ASSYMETRIC TONIC NECK REFLEX
■ Stimulated by head position■ Present at birth■ Inhibited between fourth and
sixth month■ Extension of arm and leg to the
face side■ Flexion of arm and leg to the
occipital side
DEVELOPMENTAL IMPLICATIONS
■ Asymmetrical cross lateral movements
■ Rotation around the sagittal axis
■ Foundation for auditory processing and language
■ Differentiation of left/right sides of the body and development of limb dominance
■ Hemispheric differentiation and specialization of executive functions
■ Hand-eye coordination – extension of visual focus
20
EFFECTS OF NON-INTEGRATION
■ Challenges in crossing midline■ Difficulty throwing/catching■ Difficulty tracking through midline■ Difficulty with attention, focus, and memory■ Auditory processing and/or auditory defensiveness ■ May have dyslexia or dyscalculia diagnosis■ Learning difficulties: language, reading, spelling, math,
handwriting
ATNR: QUADRUPED TEST
Quadruped Extended, yet relaxed,
arms Head in neutral Therapist turns head right Hold five seconds Turn head left Hold 5 seconds

TREATMENT SUGGESTIONS
WHAT ARE YOUR GOALS?
■ Child has full head control against gravity –measured in supine
■ Child can engage in play and functional activities without associated body reactions in response to head flexion/extension or rotation – both in static and dynamic play/functional tasks
ACTIVITIES FOR INTEGRATION
■ Facilitate correct activation of all components of the reflex
■ Modifications– Head Control – add pillow under head to
bring in neck flexion – Pelvis – place pillow/your leg under pelvis
to facilitate full flexion of lower body– Work in small ranges first
HANDS PULLINGREFLEX
22
TREATMENT IDEAS
■ “Tug-o-war” – supine; tall kneel■ Rope pull – supine/prone■ Pull/push games (isometric
engagement)■ Scooter board ■ Airplane■ Prone play
23
THINK ABOUT THE PATTERN…
Stimulus: Head
Break up head flexion/extension from full body flexion/extension
Activities that dissociate head from body
Activities that move the body against gravity
Activities that support both flexor and extensor strengthening
Activities that promote balance
TLR
TREATMENT SUGGESTIONS
Lay supine and play games that only lift the head Toss/catch a ball Visual perceptual game on the wall
Sit on scooter, hold noodle/rope bilaterally and hold co-contraction while being pulled forward
Balance activities Alter head position
