SPED 417/517 Atypical Sensory and Motor Development
Muscle tone is abnormal Primitive reflexes persist Postural control and movement are difficult Positioning and handling problems lead to orthopedic problems Functional skill development is interrupted Atypical Sensory-Motor Development
Creating interventions based on sensory qualities Creating interventions based on motor qualities Sensory-Motor Interventions
Neurodevelopmental Sensory Integrative Behavioral Cognitive Developmental Adaptive approaches Other –Joint mobilization –Myofacial release techniques –Craniosacral therapy Frames of Reference
Westling & Fox Chapter 13 Atypical sensory responses –Limited experience with touch input leading to tactile defensiveness –Inappropriate proprioceptive input due to tone differences impacting movement –Difficulty processing vestibular input leading to difficulty with position changes –Restricted diets interfere in taste experiences leading to resistance with tastes and smells Intervention techniques –Modify sensory inputs from environment –Provide sensory inputs as needed
Westling & Fox Chapter 13 Abnormal muscle tone –Affects ability to produce controlled muscle contractions –Interferes in posture and movement Intervention techniques –Inhibition and facilitation –Environment and physiology medication environmental visual & auditory inputs interactions fatigue & mood
Westling & Fox Chapter 13 Primitive reflexes –Asymmetrical tonic neck reflex (ATNR) –Symmetrical tonic neck reflex (STNR) –Tonic labyrinthine reflex (TLR) Intervention techniques –avoid positions which trigger response –facilitate opposing postures –normalize tone
Westling & Fox Chapter 13 Posture and movement –Cycle of development of abnormal movement Tone difference Difficulty sustaining body alignment Proximal adjustments Compensatory movement patterns Stereotypical posture & movement Change in muscle length Orthopedic changes
Westling & Fox Chapter 13 Intervention techniques –Positioning Remedial Compensatory –Handling Normalizing tone Facilitating normal postures
Atypical Development Prone Supine Sitting Standing Walking All-fours Oral-motor Upper body General mobility
Tone Quality Quantity Development of prone
increased, decreased, fluctuating tone fluidity, efficiency, effort alignment, adaptability Dysfunction
limited sleeping positions decreased play options limit development of trunk control interfere with mobility development Affected life tasks

impacts daily nutrition interferes with sensory exploration impacts development of communication affects personality and social interactions Affected life tasks
Tone Quality Quantity upper body
increased, decreased, fluctuating tone fluidity, efficiency, effort alignment, adaptability Dysfunction
lack of exploration of environment decreased dexterity and bilateral control limits play skills and learning potential interferes with daily life tasks Affected life tasks
Tone Quality Quantity general mobility
increased, decreased, fluctuating tone fluidity, efficiency, effort alignment, adaptability Dysfunction
affects independence interferes with play skills limits exploration of environment limits transitions impacts development of postural control Affected life tasks
Consider routine task How does difference in tone affect task? How does quality of movement affect task? How does quantity of movement options affect task? Application
