The acquisition of coordination in handwriting was studied by comparing aspects of the limb dynamics in dominant and nondominant limbs, and having subjects learn to write their signature and produce repetitive cursive e's with their nondominant arm. Analysis of the motion of the limb links revealed that naturally right-handed subjects using their nondominant limb locked their distal limb joints and tended to write with the more proximal joints in contrast to the organization displayed by the dominant limb. Left-handed subjects did not demonstrate differences in phase-locking between the dominant and the nondominant limb. In contrast, they showed high correlations in the proximal linkages for both dominant and nondominant limbs. The findings revealed strong differences in limb organization between naturally dominantright- and left-handed subjects but these respective styles of coordination were transferred to …
