Editing Graphology (section)

=== Medical diagnosis ===
Medical graphology is probably the most controversial branch of handwriting analysis.<ref>{{cite journal |last1=Ludewig |first1=Reinhard |last2=Dettweiler |first2=Christian |last3=Lewinson |first3=Thea Stein |title=Möglichkeiten und Grenzen der Medizinischen Graphologie |trans-title=Possibilities and limits of medical graphology. Determination of current status and perspectives (I) |language=de |journal=Zeitschrift für die gesamte innere Medizin und ihre Grenzgebiete |date=December 1992 |volume=47 |issue=12 |pages=549–57 |pmid=1285461 }}</ref> Strictly speaking, such research is not graphology as described throughout this article but an examination of factors pertaining to [[motor control]]. Research studies have been conducted in which a detailed examination of handwriting factors, particularly timing, fluidity, and consistency of size, form, speed, and pressure are considered in the process of evaluating patients and their response to pharmacological therapeutic agents.<ref>{{cite journal |last1=Knopp |first1=W |last2=Paulson |first2=G |last3=Allen |first3=JN |last4=Smeltzer |first4=D |last5=Brown |first5=FD |last6=Kose |first6=W |title=Parkinson's disease: L-dopa treatment and handwriting area |journal=Current Therapeutic Research, Clinical and Experimental |date=March 1970 |volume=12 |issue=3 |pages=115–25 |pmid=4985489 }}</ref> The study of these phenomena is a by-product of researchers investigating motor control processes and the interaction of nervous, anatomical, and biomechanical systems of the body.

''The Vanguard Code of Ethical Practice'', amongst others, prohibits medical diagnosis by those not licensed to do diagnosis in the state in which they practice.
