Effect of Pencil Grasp on the Speed and Legibility of Handwriting in Children / Heidi SCHWELLNUS in American Journal of Occupational Therapy, Vol. 66/6 (novembre-décembre 2012)

Pencil grasps other than the dynamic tripod may be functional for handwriting. This study examined the impact of grasp on handwriting speed and legibility. METHOD. We videotaped 120 typically developing fourth-grade students while they performed a writing task. We categorized the grasps they used and evaluated their writing for speed and legibility using a handwriting assessment. Using linear regression analysis, we examined the relationship between grasp and handwriting. RESULTS. We documented six categories of pencil grasp: four mature grasp patterns, one immature grasp pattern, and one alternating grasp pattern. Multiple linear regression results revealed no significant effect for mature grasp on either legibility or speed. CONCLUSION. Pencil grasp patterns did not influence handwriting speed or legibility in this sample of typically developing children. This finding adds to the mounting body of evidence that alternative grasps may be acceptable for fast and legible handwriting.

Writing forces associated with fo / Heidi SCHWELLNUS in American Journal of Occupational Therapy, Vol. 67/2 (mars-avril 2013)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 67/2 (mars-avril 2013) . - p. 218-227 Titre : Writing forces associated with fo Type de document : texte imprimé Auteurs : Heidi SCHWELLNUS ; et al. ; Azadeh KUSHKI ; Heather CARNAHAN Année de publication : 2013 Article en page(s) : p. 218-227 Langues : Anglais (eng) Mots-clés : Préhension  Ecriture Résumé : OBJECTIVE. We investigated differences in handwriting kinetics, speed, and legibility among four pencil grasps after a 10-min copy task. METHOD. Seventy-four Grade 4 students completed a handwriting assessment before and after a copy task. Grip and axial forces were measured with an instrumented stylus and force-sensitive tablet. We used multiple linear regression to analyze the relationship between grasp pattern and grip and axial forces. RESULTS. We found no kinetic differences among grasps, whether considered individually or grouped by the number of fingers on the barrel. However, when grasps were grouped according to the thumb position, the adducted grasps exhibited higher mean grip and axial forces. CONCLUSION. Grip forces were generally similar across the different grasps. Kinetic differences resulting from thumb position seemed to have no bearing on speed and legibility. Interventions for handwriting difficulties should focus more on speed and letter formation than on grasp pattern.
