Arnadottir Occupational Therapy Neurobehavioral Evaluation
What It Measures
The A-ONE, now called the ADL-focused Occupation-based Neurobehavioral Evaluation, works out which thinking and perceptual problems are getting in the way of everyday self-care. A therapist watches the person dress, groom, transfer, and eat — 20 everyday tasks across five domains — rather than testing skills at a table.
Two scales run at once. The ADL scale rates how much help each task takes, from full assistance to independent. The neurobehavioral scale identifies what caused the trouble: motor or ideational apraxia, unilateral body or spatial neglect, spatial relations problems, organization and sequencing difficulty, perseveration, aphasia, and pervasive issues like attention or initiation. Because errors are scored by how much they interfere with the task, impairment and daily function are linked directly.
