title: Effects of sensory information, movement direction, and hand use on fine motor precision.
abstract: The differences in fine motor precision over line model in different sensorial conditions (visual-proprioceptive and proprioceptive only) for different movement directions (transverse, frontal, and sagittal) and both hands were measured digitally with use of special software. The observed variables were directional (D) and formal (F) deviations, together with changes of line length (LL) from the base model. Analysis indicated non-significant differences for all measured variables for hand use, while for the remaining factors (sensory test condition and movement direction), the differences were significant for all levels. Both sensory information and movement directions are important for hand-drawing precision, not just the specific hand used.
