Artistic Clues to Psychogenic Tremor Using Pen and Paper

Just as graphologists surmise personality traits based on a person's handwriting, clinicians should use the drawing of Archimedes spirals, lines, and written sentences to differentiate psychogenic from pathologic tremors. Although script patterns vary based on tremor type, Hess et al1 demonstrated that the Archimedes spiral was poorly reproducible in patients with psychogenic tremor. We propose that intact fine motor control in these patients creates script with high amplitude oscillations without compromising legibility.
