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.
