“…Examples are visual-motor integration, visual perception, fine motor function, kinaesthesia and biomechanical factors such as writing grasp, posture and muscle tone. Although the relationship of most of these performance components to handwriting speed and legibility has been examined (e.g., Feder & Majnemer, 2003;Goyen & Duff, 2005;Kaiser, Albaret & Doudin, 2009;Klein, Guiltner, Sollereder & Cui, 2011;Ryan, Rigby & Campbell, 2010;Schwellnus et al, 2012;Volman, van Schendel & Jongmans, 2006;Weintraub & Graham, 2000), substantial limitations exist in many of the studies. Participants in some studies did not have handwriting difficulties and some assessments used for identifying deficits in performance components had not been evaluated for psychometric rigour.…”
