[Purpose] This study examined the cut-off point of the Trail Making Test in predictingthe risk of unsafe driving in stroke patients. [Subjects and Methods] A total of 81 strokepatients with a driver’s license participated in this study. The DriveABLE CognitiveAssessment Tool, Trail Making Test-A, and Trail Making Test-B evaluations were conductedin all participants. All participants were classified into the safety or risk groups basedon the DriveABLE Cognitive Assessment Tool evaluation results. The Trail Making Testresults underwent a receiver operating characteristic analysis in each group. [Results]The results of the receiver operating characteristic curve analysis showed that thecut-off point for Trail Making Test-A was 32 seconds and the cut-off point for TrailMaking Test-B was 79 seconds. The positive predictive values of the Trail Making Test-Aand Trail Making Test-B were 98.3% and 98.3%, respectively, and the negative predictivevalues of the Trail Making Test-A and Trail Making Test-B were 81.0% and 73.9%,respectively. [Conclusion] The Trail Making Test is a useful tool for predicting the riskof unsafe driving in stroke patients. This tool is expected to be used more actively forscreening stroke drivers with respect to their cognitive function.
