Graphomotor skills with children


The primary objective of a study carried out at Kinderspital Zürich by Nicole Lüscher, Dr. Brigitte Wirth and Dr. Huub van Hedel, was to determine the reliability of pen pressure measurements recorded with the Metrisquare DiagnoseIS software, and the validation of a visual perception test performed on a graphic tablet. Moreover, motivational aspects of working with such an electronic device were examined. Finally, the correlation between results from the visual perception test and the level of impairment where investigated. After the performance of four pen-pressure measurements by the investigator, eighteen children with various neurological diagnoses participated in two measurement sessions where a visual perception test on paper and on an electronic tablet was completed and two pressure exercises and functional assessments were performed. As shown with this investigation, the Metrisquare solution in combination to an electronic tablet is a reliable tool to work on graphomotor skills with children, especially for pressure related tasks.
