The screen consists of learning three visual-motor tasks (leather-lacing stitches) with increasingly complex activity demands. Completion of the three tasks requires that the person attend to, understand, and use sensory and motor cues from the material objects (leather, lace, and needles), the administrator’s verbal and demonstrated instructions and cues, and feedback from motor actions while making the stitches. The scores obtained are interpreted using the Allen Cognitive Scale of levels and modes of performance. The screen is available in two forms: the standard Allen Cognitive Level Screen (ACLS) and a larger form (LACLS) for persons with vision or hand function problems. Continue reading
The diagnostic accuracy of Addenbrooke’s Cognitive Examination (ACE) as a brief ‘bedside’ cognitive screening instrument has led to its widespread adoption. Nonetheless, certain weaknesses have been identified in the ACE, prompting the development of the Addenbrooke’s Cognitive Examination-Revised (ACE-R). The ACE-R has been reported to have excellent sensitivities and specificities (>0.8) for the diagnosis of dementia at cut-off scores of 88/100 and 82/100 in the setting of a university hospital clinic.
Routine Task Inventory-Expanded (RTI-E) is an assessment of cognitive abilities in the context of routine daily activities. Developed by Claudia Allen in 1989 a manual was later developed by Noomi Katz, PhD, OTR, (Professor of Occupational Therapy at Hebrew University, Jerusalem) in order to encourage others to use this tool in clinical practice, and research.
