Novel rule-based static and dynamic feature extraction from figure copying tasks for the detection of visuo-spatial neglect
Novel rule-based static and dynamic feature extraction from figure copying tasks for the detection of visuo-spatial neglect
A series of static rule-based assessment criteria and dynamic constructional features are defined and used to analyse the hand-drawn responses from a geometric figure copying task. Assessment subjectivity is removed by the algorithmic definition of analysis criteria and test diagnostic sensitivity to the condition of visuo-spatial neglect is increased through the analysis of the novel dynamic features. This sensitivity increase is demonstrated by the identification of constructional performance deficits in test responses which appear 'normal' by conventional static assessment. The investigation is carried out with a population of stroke patients.

Abstract
A series of static rule-based assessment criteria and dynamic constructional features are defined and used to analyse the hand-drawn responses from a geometric figure copying task. Assessment subjectivity is removed by the algorithmic definition of analysis criteria and test diagnostic sensitivity to the condition of visuo-spatial neglect is increased through the analysis of the novel dynamic features. This sensitivity increase is demonstrated by the identification of constructional performance deficits in test responses which appear 'normal' by conventional static assessment. The investigation is carried out with a population of stroke patients.
