Graphomotor and Handwriting Disabilities Rating Scale (GHDRS):towards complex and objective assessment

TL;DR

This paper introduces the GHDRS, a new objective scale for diagnosing and assessing graphomotor and handwriting disabilities in children, supporting detailed quantification of 17 manifestations to improve diagnosis accuracy.

Contribution

The paper presents a novel, transparent scale (GHDRS) for complex, computer-aided assessment of GD and HD, addressing limitations of subjective current methods.

Findings

Supports quantification of 17 manifestations

Enables objective and complex diagnosis

Designed for adaptability across languages

Abstract

Graphomotor and handwriting disabilities (GD and HD, respectively) could significantly reduce children's quality of life. Effective remediation depends on proper diagnosis; however, current approaches to diagnosis and assessment of GD and HD have several limitations and knowledge gaps, e.g. they are subjective, they do not facilitate identification of specific manifestations, etc. The aim of this work is to introduce a new scale (GHDRS Graphomotor and Handwriting Disabilities Rating Scale) that will enable experts to perform objective and complex computeraided diagnosis and assessment of GD and HD. The scale supports quantification of 17 manifestations associated with the process/product of drawing/ handwriting. The whole methodology of GHDRS design is made maximally transparent so that it could be adapted for other languages.
