It is a discipline that studies human occupational performance. In the child population, it focuses on the areas of self-care, play and schooling as vital performance channels for the personal fulfillment of the child.

When there is a sample of dysfunctional actions in these areas, the occupational therapist performs a detailed assessment of the performance components (sensory-motor, cognitive-perceptual and personal-social), in order to determine the causes and provide the relevant and effective intervention, to enable the articulation of these components in functional performances at the age and level of schooling of the child.
