Despite the widespread beliefs that handwriting is purely a motor skill or that only multisensory methods are needed to teach handwriting, multiple language processes are also involved in handwriting. Handwriting draws on language by hand (letter production), language by ear (listening to letter names when writing dictated letters), language by mouth (saying letter names), and language by eye (viewing the letters to be copied or reviewing for accuracy the letters that are produced from memory) (Berninger & Wolf, 2016).
The characteristics of dysgraphia include the following:
Variably shaped and poorly formed letters
Excessive erasures and cross-outs
Poor spacing between letters and words
Letter and number reversals beyond early stages of writing
Awkward, inconsistent pencil grip
Heavy pressure and hand fatigue
Slow writing and copying with legible or illegible handwriting (Andrews & Lombardino, 2014)
The observable written expression characteristics are most often associated with the following cognitive skill deficits:
Impaired feedback the brain is receiving from the fingers
Weaknesses using visual processing to coordinate hand movement and organize the use of space
Problems with motor planning and sequencing
Difficulty with storage and retrieval of letter forms (Levine, 1999)
Additional secondary consequences of dysgraphia may also include:
Difficulty with unedited written spelling
Low volume of written output as well as problems with other aspects of written expression
Dysgraphia is not:
Evidence of a damaged motor nervous system
Part of a developmental disability that has fine motor deficits (e.g., intellectual disability, autism, cerebral palsy)
Secondary to a medical condition (e.g., meningitis, significant head trauma, brain trauma) • Association with generalized developmental motor or coordination difficulties (Developmental Coordination Disorder)
Impaired spelling or written expression with typical handwriting (legibility and rate) (Berninger, 2004)
