| Summary: |
The present thesis for doctorate compared tapping movements of schizophrenic patients to normal controls. Also the possible influnces of social or clinical signs (especially the neuroleptical medication) were examined. The movements of the index finger were recorded by a ultrasound measurement system. First of all important methological questions had to be answered in some preliminary studies. After this both self-paced and externally-paced tapping (conditions: fluently, as fast as possible, given beat 100 bpm and 200 bpm) was examined. The hypotheses based of an extensive summary of the literatur of finger tapping in schizophrenia. The comparison of the two groups showed significant increased intraindividual variabiltity of motor performance under any of the experimental conditions and significant decreased maximal tapping frequency in schizophrenic patients. While the amount of muscular rigidity due to neuroleptic medication seems to decrease maximal tapping frequency, the intraindividual variability might be almost independent of neuroleptical medication.

| Summary in another language: |
In der vorliegenden Dissertation wurde mit Hilfe einer Ultraschall-Meßanlage das Finger-Tapping schizophrener Patienten und gesunder Kontrollprobanden dreidimensional aufgezeichnet und miteinander verglichen. Des Weiteren wurde der Einfluss biosozialer und klinischer Variablen, insbesondere der der neuroleptischen Medikation, auf die Tappingbewegung untersucht. Da es sich um eine neuartige Untersuchungsmethode handelt, mussten zunächst im Rahmen von Vorstudien mehrere grundlegende methodische Fragen geklärt werden. Die Aufnahme der Tappingbewegung erfolgte unter verschiedenen Bedingungen (flüssig, schnellstmöglich, Taktvorgabe 100 bpm, Taktvorgabe 200 bpm). Grundlage für die Untersuchungshypothesen bildet eine umfangreiche Literaturübersicht zum Finger-Tapping bei schizophrenen Patienten. Im Gruppenvergleich zeigte sich, dass schizophrene Patienten unabhängig von der Untersuchungsbedingung in der Ausführung der Tappingbewegung variabler sind und unter der Bedingung schnellstmöglich geringere maximale Tappingfrequenzen produzieren. Während sich ein signifikanter Einfluss der neuroleptisch bedingten Rigidität auf die Tappingfreuquen zeigte, scheint die höhere intraindividuelle Variabiltät bei schizophrenen Patienten unabhängig von der Medikation.
