Inter-rater reliability of the neurological examination in schizophrenia. Schizophr. Res. 29, 287-292]. Exploratory factor analysis in the overall sample (n = 110) revealed three factors of interest: a "coordination/Romberg" factor (which included the fist-edge-palm test, finger-thumb opposition, rapid alternating movements, and the Romberg test), a "sensory integration" factor (which inc...Continue Reading
