title: Use of the Tower of London - Drexel University, Second Edition (TOLDX) in adults with traumatic brain injury.
abstract: The Tower of London - Drexel University, Second Edition (TOL(DX)) was investigated in order to determine the efficacy of using this instrument in evaluating the impact of traumatic brain injury on cognitive functioning in adults. Performance on the TOL(DX) was compared among 56 individuals with complicated mild to severe traumatic brain injury ("sTBI"), 68 individuals with uncomplicated, mild traumatic brain injury ("mTBI"), and 124 demographically matched, healthy controls. Both TBI groups performed worse than controls on TOL(DX) measures of executive time (ET) and number of moves used (TMS), but only patients with sTBI were more likely to be impaired on TMS (i.e., performing at least 1.5 SD below the mean). Poorer performance on TMS was associated with increasing length of coma. Although poor sensitivity of this measure limits its use in isolation, the TOL(DX) may provide a complementary measurement of aspects of problem-solving deficit in TBI that may not be captured by other tests.
