Using spatio-temporal data from trail-making tests to assess neglect

We designed an app based on the Trail-Making Test for assessment and rehabilitation of hemi-spatial neglect. A randomized controlled trial with thirty-six participants showed that player performance in the game was significantly affected by their cognitive conditions verified by standard neuropsychological tests and the nature of their lesions. A mixed ANOVA revealed that the average time going from one target to the next was significantly affected by the interaction of their neglect scores and the goal position relative to the side of their lesion. The group testing positive for neglect had an average delta time of 3.51 second on targets lateral to the lesion and 5.21 for contra-lateral targets.
