Abstract
SUMMARY A modification of an earlier rating scale for extrapyramidal system disturbance is described, and evidence for the validity and reliability of the scale is presented. The usefulness of the scale in studies of neuroleptic drugs is discussed. By its application it is possible to quantify extrapyramidal side effects and to separate them into four principal factors.
