Model (conceptual)

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.

The four-quadrant model of facilitated learning (4QM) is used by teachers and practitioners in selecting effective learning strategies based on changing needs of the learners during acquisition of new skills. When occupational therapists use skill acquisition as intervention strategy, the 4QM provides a way of understanding, planning, and organizing the use of learning strategies. Through acquiring occupational performance components, the goal is for improve performance in the targeted occupation.

The Dynamic Model for Play Choice emphasizes that a child’s choice of play is the result of a dynamic interaction among four characteristic categories, including relational (peers, adults, siblings, cooperation, shared or deferred choice), child (age, gender, ability), activity (level of difficulty, active/passive), and contextual (location, weather). The perceived fun activities with appropriate level of challenge are repeated because of the positive emotion which attached to the activity like fun and happiness and therefore, preference is emerged.

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.

The Conceptual Model for Performance in Handwriting views that handwriting is important for one’s work and/or education domains of occupations. It considers the performance components, performance areas (functional performance), performance contexts, and the interactive relationship among them. Prerequisites to handwriting include performance components in sensory, perceptual, motor cognitive, and language functions, as well as integrations of these components.

The Functional Model of Cognitive Rehabilitation (FMCR) applies general concepts from the Canadian Model of Occupational Performance (CMOP). It aims to complement to the CMOP for choosing, organizing, and performing useful and perceived meaningful occupations in order to addresses the cognitive performance component. In the CMOP, the cognitive performance components include perception, concentration, memory, comprehension, and judgement. The FMCR recognizes the dynamic interaction between clients and their environments (physical, cultural, and social).

The children’s play model views play as necessary and the main occupation of children. An episode of joyful, self-chosen play from children’s perspective is symbolized by a sandcastle diagrammatic model. Play shares similar characteristics with a sandcastle, each component of the sandcastle describes a component of a play episode. Overall, a play episode is like a sandcastle, it is complex and temporary, and constructed for playfulness. It can happen in various contexts, like alone or with family or a group of peers, either spontaneously or planned.

The Canadian Model of Occupational Performance and Engagement (CMOP-E) is an occupational performance model, which is evolved from the Canadian Model of Occupational Performance (CMOP). The CMOP-E includes three main components: person, environment, and occupation. In this model, the inner part represents “Person”, and its center is the spirituality of a person. The other components surrounding a person’s spirituality are affective, physical, and cognitive abilities.

The Occupational Performance Model (Australia) is a model proposing that people fulfill their occupational performance roles by engaging in routines, tasks and activities, in the domains of self-maintenance, productivity, leisure and rest, in the process responding to internal and/or external demands of the environment. This model assumes that engagement in occupations provides the sense of competence, autonomy, temporal organization, and meaning of existence to individuals. It focuses on activation of person-environment relationship through participation in occupations.

The Allen’s Cognitive Disabilities Model (CDM) emphases on the integration of the cognitive functional ability and the level of activities that clients are able and willing to perform. Interventions using this model can take place individually or in group. When implementing the intervention, therapists consider each client’s needs and implement changes in task accordingly. In group sessions, each client’s cognitive mode of performance is considered individually and adapted to the modified task with appropriate level of required cognitive functional ability.
