The aim of this study was to quantify stability of nondominant handwriting
kinematics and legibility in participants with functional loss of the previously
dominant hand. Twelve adult volunteers provided two handwriting samples 6 weeks
apart. Handwriting tasks (Compose a Sentence,
Copy Alphabet, Copy Date,
Copy Sentence, and Draw Circles) were performed in cursive writing on standard white,
lined paper taped to a digitizer to record kinematic and kinetic variables of
velocity, displacement, force, and on-paper time. Results showed minimal
performance variability within subjects and marked variability between subjects,
as well as variability between tasks for all participants. Stylistic stability of
the handwriting samples was assessed by two independent evaluators. These
evaluators matched all handwriting samples at test to retest times with 89%-100%
accuracy, suggesting value in the "whole" handwriting sample and emphasizing the
idiosyncratic nature of handwriting. Results suggest that handwriting skill
stability in the previously nondominant hand varies across subjects and task demands.
