Introduction to the Orientation Log

The Orientation Log (O-Log) was developed to measure orientation to time, place, and circumstance in a rehabilitation population. The O-Log can be used for serial assessment of orientation to document changes over time. This can be very helpful in documenting progress that could help justify continuing treatment. The instrument can be used with anyone who is potentially disoriented; the questions are not specific to any disorder. Thus far the O-Log has been used with people experiencing TBI, CVA, tumor, infectious disease, and degenerative disorders. Each of the 10 questions comprising the O-Log are objectively scored and the scale can be presented in just a few minutes.

Information regarding the O-Log was contributed by the University of Alabama at Birmingham Traumatic Brain Injury Care System. Please contact Tom Novack, Ph.D., at for more information.
