Identifying akinesia and akathisia: the relationship between patient's self-report and nurse's assessment.

This study examines the relationship between the self-reports of 96 out-patients at four community mental health centers and nursing assessments of these same patients regarding drug-induced akinesia and akathisia. Akinesia, diminished spontaneity characterized by motor slowness and stiffness, and akathisia, a feeling of inner restlessness, are common but often misdiagnosed side effects of neuroleptics. Significant positive correlation was found between self-reports and nursing assessments. Data indicate that specific subjective responses as well as systematic clinical examination should be included when assessing for drug-induced akinesia and akathisia.
