Spatial Exploration Indicators in the Remote Assessment of Visual Neglect

The visual neglect is a visuo-spatial attention disorder associated with stroke events and its presence is considered a negative prognostic factor of functional recovery. The specific assessment tests that are most frequently administered to evaluate the presence of this disorder are "paper and pencil tests", such as barrage tests. The current work presents the digital version of the Albert's barrage test for the evaluation of the Unilateral Spatial Neglect (USN) as it has been integrated into the ReMoVES tele-rehabilitation system. The data captured by this activity is broader and more complete than the information extractable from the paper version, including the order of the exploration sequence, work trajectories, punctual speed and other indicators. The procedure is preliminarily validated both on a control group of healthy subjects and on some patients. Several sessions are examined with the aim of observing which parameter of the digital Albert Test is statistically more significant for verifying the similarity in behavior between non-pathological subjects and the possible improvement over time of two pathological case studies.
