[Psychosomatic determinants of graphospasm].
As there is a variety of psychic and somatic variables in its genesis, the writer's cramp could be a syndrome of different subtypes. Therefore 62 former psychotherapy-patients with writer's cramp were examined according to a design of several dimensions in order to find out if there were any subtypes. The parts of the examination were exploration, structural interview, neurological examination, psychological examination of the personality, examination of some electrolytes in serum and radiograph of neck spinal column. Different multivariate statistical methods isolated two subtypes of patients with writer's cramp. The first group comprises patients with fine and/or big dysfunctions of motor activity, the symptoms are independent of psychic factors or of psychotherapy. The second group is characterized of a monosymtomatic writer's cramp, of a neurosis and of remissions of motoric symptoms following psychotherapy. The examination shows that fine and/or big dysfunctions of motor activity which often co-occur the writer's cramp are important criteria for differential diagnosis and indications.
