Writing Forces and Pencil Grasps

The American Journal of Occupational Therapy published research on the writing forces associated with four pencil grasp patterns in 74 children in grade 4.The students completed a handwriting assessment before and after a copy task and grip and axial forces were measured. The results indicated the following:

  • no kinetic differences among grasps, whether considered individually or grouped by the number of fingers on the barrel.
  • when grasps were grouped according to the thumb position, the adducted grasps exhibited higher mean grip and axial forces.
  • Grip forces were generally similar across the different grasps.
  • Kinetic differences resulting from thumb position seemed to have no effect on speed and legibility.

The researchers concluded that interventions for handwriting difficulties should focus more on speed and letter formation than on grasp patterns.

Handwriting Rubrics – This is an electronic book of 26 rubrics to assess handwriting. A rubric is a scoring guide to judge performance on a specific task.   Have you ever wanted to quantify handwriting skills such as letter formation, speed or copying? Handwriting Rubrics can be used as assessment tools to quantify an individual’s written productivity. By using the rubric, each individual can be scored based on the same criteria.
