Objective: Schizophrenia patients suffer from a variety of motor symptoms, including parkinsonism, catatonia, neurological soft signs, abnormal involuntary movements and psychomotor slowing. Methods: Literature review of prevalence rates and presentation of own results. Results: Parkinsonism and abnormal involuntary movements are intrinsic to schizophrenia, but may also be evoked by antipsychotic treatment. Reduced motor activity is associated with negative symptoms, catatonia and psychomotor slowing. Furthermore, 40 % of schizophrenia patients are impaired in gesture performance, which is related to executive and basic motor function. Mild motor disturbances are found in the majority of patients, while severe dysfunctions are limited to a minority. Our neuroimaging studies suggest that hypokinesia is caused by defective cortico-subcortical motor loops in schizophrenia. Taken together, a dimensional approach to schizophrenia motor symptoms seems promising. A purely descriptive assessment of motor signs is preferred over theoryladen categorization. Using objective motor parameters allows finding neural correlates of abnormal motor behaviour. Conclusion: The motor dimension of schizophrenia is linked to distinct disturbances in the cerebral motor system. Targeted modification of the defective motor system might become a relevant treatment option in patients suffering from schizophrenia with predominant motor features.
