- statistical analysis indicated that variance in handwriting based on the assessments was greater than or equal to 20% for legibility and greater than or equal to 26% for speed
- only scores on the Developmental Test of Visual Motor Integration were different between skilled and non skilled handwriters
The researchers suggest that occupational therapists explore other influential factors besides sensory motor for handwriting difficulties because of low correlations between the assessments and handwriting ability.
