Computerized Evaluation of Fine-Motor Symptoms

Abstract

The computerized evaluation of the handwriting test according to Haase provides, for the first time, an objective method of an individual dosage of neuroleptics based on the severity of fine-motor inhibition. The extrapyramidal-motor side-effects of neuroleptics are caused by blocking the post-synaptic dopamine receptors in the corpus striatum. At the beginning of treatment dyskinetic reactions may occur, e.g. a neckface syndrome, and later on the characteristic Parkinson syndrome with akinesia, for instance. Our method aims at preventing these coarse-motor side-effects.
