Oral adaptation of the Trail Making Test: A practical review.

Despite being one of the most widely used measures in clinical neuropsychology, the Trail Making Test is highly reliant on intact vision and motor functioning. Given that these capacities are often compromised in patients requiring neuropsychological evaluation, various authors have proposed methods for adapting the Trail Making Test for oral administration. To date, a number of administration and score transformation methods have been proposed. We reviewed the existing literature on oral adaptation of the Trail Making Test in order to provide recommendations for practicing clinicians wishing to use the measure, and to highlight directions for future research.
