Abstract: | An automated bisection device (ABD) is described that is designed for use in assessing the direction of three-dimensional neglect in various clinical populations. This device features an apparatus containing two base sections and a connecting rod, on which is located a bisection indicator assemblage that can be moved either by hand or by a calibrated motor-drive system. The indicator assemblage is, in turn, connected to a motor-control box with variable speed settings and a digital readout. The ABD can be used to measure bisection estimations along all three linear axes (lateral, vertical, and depth) by providing visual cues alone, tactile cues alone, or a combination of visual and tactile cues. |
