Occupational Therapy Delineation Model of Practice for Children with Attention Deficit Hyperactivity Disorder

Sensory Integration Theory aims to explain behaviors, plan intervention, and predict behavioral change through intervention, and provide specific intervention strategies to remediate the underlying sensory issues that affect functional performance. It purposes therapeutic interventions that incorporate sensation to affect multi-sensory perception to influence learning and behavior, as the central nervous system does not process sensory information in isolation.

The Dunn’s Model of Sensory Processing proposes four basic patterns of sensory processing which are emerged from the interaction of the neurological threshold and self-regulation. Neurological threshold is a personal range of threshold for noticing and responding to different sensory events in everyday life. People who have low sensory threshold would notice and respond to stimuli more often because their neurological system activates easier and more readily to sensory events.

This frame of reference adapts a top-down approach to identify visual perceptual factors that limit an individual’s daily participation, and adaptive and compensation approaches are used to facilitate engagement in meaningful occupation. It uses theories from cognition, developmental psychology, education, and Warren’s developmental hierarchy of visual perceptual skills. Visual Perceptual skill development is viewed to be developed from a hierarchy, starting from oculomotor control, visual fields, visual acuity.

Moyers Model is a model that helps to treat people with alcohol dependence. This model suggests that alcohol dependence is resulted from a complex interaction of causal factors. These factors may include genetic predisposition, negative character development/experience in family history, which lead to impaired interpersonal and coping skills, availability of alcohol, peer group affiliation and social norms that accept and promote use of alcohol.

The Hand Function Evaluation Model (HFEM) aims to guide assessment of the impairment and disabilities for preschool-age children presenting hand dysfunction. In the HFEM, hand function is evaluated at three levels: 1) sensorimotor performance, 2) developmental progress, and 3) hand function performance. At the first level, assessment of sensorimotor performance includes grip strength, dexterity, and stereognosis of the child. In particular, the evaluation of the grip strength includes four subtypes: power, tip pinch, three point chuck, and lateral pinch grip.
