ABSTRACT
This chapter is a comprehensive reference manual providing information on the Orientation Log (O-Log), which is an objective, clinician-administered test developed to provide a brief bedside assessment of orientation. It was designed for evaluating degrees of confusion in people with traumatic brain injury, as well as patients receiving rehabilitation for other neurological conditions including hypoxia, infections, stroke and tumor. A brief history of the instrument's development is provided, along with a description of item content and administration/scoring procedures. Psychometric properties are reviewed and a critical commentary is provided. Key references are cited and in most cases the actual scale is included, giving the reader easy access to the instrument.
