Motor (and Sensory) Development • Why is it important? • This is my new favorite article: • https://www.ewi-ssl.pitt.edu/psychology/admin/faculty-publications/201008311333100.Iverson_2010.pdf • http://www.people.com/people/archive/article/0,,20353593,00.html • http://www.autismspeaks.org/science/science_news/kennedy_krieger_early_signs.php
Review • “Development results from interrelated processes of maturation, physical growth, and learning and may be observed in genetic and environmental adaptation”- Cech & Martin (2002), p. 51. • Maturation= genetics/biophysical • Adaptation= body’s response to the environment • The progression from reflex dominance to increasingly advanced motor skills
Motor Development Concepts • Sequential: across cultures, despite individual differences • Directional concepts: • Cephalocaudal • Proximaldistal • Mobility & Stability: the relationship between these is=postural control • Sensory Input: first movements or reflexes are initiated by sensation and continues with voluntary control.
Sensory Input • Vision • Somatosensory: • Tactile: • Proprioception: interpreting stimuli originating in muscles, joints and other internal tissues that give info. about position of body part in relation to another • Vestibular: interpreting stimuli from the inner ear receptors regarding head position and movement
Reflexes • Predictive movements in response to a stimuli • The integration of reflexive reactions follows a sequence that correlates with the acquisition of motor skills • Present in the neonatal and become integrated in time; persistence beyond the time of anticipated decline may signal brain abnormalities • Almost all reflexes should be integrated by 9-12 months Motor Development

Emergence of Postural Reactions • Righting • Protective • Equilibrium • See Table 9-2 • Nature versus Nurture
Postural Reactions • Automatic responses to sensory input that act to keep the body parts in alignment, maintain equilibrium and prevent injury. • Are of primary importance with static and dynamic balance. • Appear between 2-18 months, with few exceptions, persist throughout life. • 3 categories: righting, protective, and equilibrium Motor Development
Righting Reactions: adjustments of the head and trunk • Automatic postural responses elicited by sensory input that signal that the head or trunk is not in midline. • Think of examples… Motor Development
Protective Reactions: extension of the limbs when balance is challanged • To prevent or break a fall. • Elicited by vestibular input that signals a change in head position. • These reactions are often delayed or absent in persons with severe disabilities. • How would this impact occupational performance??? Motor Development
Protective Reaction Motor Development
Equilibrium Reactions: total body responses • To prevent falls • Elicited by vestibular input from any position. • Appear between 5-18 months of age and persist for life. • 5 key positions for testing: • Prone, supine, sitting, all fours, and standing (tilt board) Motor Development
Equilibrium Reaction Motor Development
Motor development • Variations exists in all areas of development • ”Abnormal motor development cannot be recognized and correctly interpreted without a solid knowledge of normal motor development” (Piper & Darrah, 1994, p.2) • Use normal motor development as a reference point to understand abnormal motor development and establish treatment techniques Motor Development
Problems Associated with Retention of Primitive Reflexes Conditions: • CP • TBI • Genetic Syndromes • ….What are these related to? • NEUROLOGICAL INTEGRITY • http://aut.sagepub.com/content/early/2011/05/19/1362361311402230.abstract Motor Development
Characteristics of Immature Movement PatternsNeurological Problems • Inconsistency • Perseveration • Mirroring • Asymmetry • Loss of dynamic balance • Falling after performance • Extraneous movements • Inability to maintain rhythm or pattern • Inability to control force • Inappropriate motor planning Motor Development
A delay in motor development occurs if: • Primitive reflexes do NOT appear in the first year of life. • Primitive reflexes appear, but do NOT DISAPPEAR by the end of the first year. • Equilibrium reactions do not appear by the end of the first year. • Equilibrium reactions do not persist throughout life. • http://pathways.org/awareness/healthcare-professionals/early-motor-surveillance/ Motor Development
Muscle Tone • The degree of normal tension in a specific muscle or muscle group • The resistance of passive stretch • Constant state of reflex contraction • For body posture Motor Development
Disorders of Muscle Tone • Hypotonus • Too little tension • Characterized by unusual postures and increased joint ROM • Hypertonus • Increase muscle tone • Too stiff to perform movements properly • Spasticity and rigidity significantly limit ROM • Athetosis • Exhibit both hyper and hypo tonus Motor Development
Recognizing Early Motor Delays • At Four and Six Months of Age Today, 1 in 40 children in the U.S. has an early motor delay. 1 • Celebrating over 25 years of assuring the best for all babies’ development • 1Statistics compiled by the Pathways Awareness Medical Round Table from a variety of sources, including the March of Dimes, Pediatrics Annual Summary of Vital Statistics, and the Centers for Disease Control and Prevention

Early motor delays can later affect a child’s ability to learn basic skills such as grasping, crawling, standing, walking, and talking.

The components of developmental surveillance include eliciting and attending to parental concerns, obtaining a relevant developmental history, making accurate and informative observations of children, and sharing opinions and concerns with other relevant professionals.”2 Observe in more than one position Observe the quality of the movement
