Application of the oral trail making test to a mixed clinical sample

The oral and written versions of the TMT were evaluated with respect to demographics and task performance levels in a mired clinical population Age, motor speed as well as written TMT-B performance scores were analyzed. Although differences were found among the raw scores for the various tasks, the ratio of written to oral TMT-B did not differ regardless of age, motor speed or TMT-B performance. The findings support earlier studies comparing the two versions of the TMT and indicate that this alternate version of the TMT appears to be a viable assessment tool for patients who have limited visual or motor skills.
