AIMS
Also written as: AIMS — Abnormal Involuntary Movement Scale
A standardized assessment tool used to detect and monitor abnormal involuntary movements, particularly tardive dyskinesia.
Full Definition
The Abnormal Involuntary Movement Scale is a 12-item clinician-rated scale designed to systematically assess involuntary movements in patients receiving antipsychotic medications. The scale evaluates movements in the facial and oral area, extremities, and trunk, with each item scored on a 5-point severity scale. AIMS is considered the gold standard for detecting and monitoring tardive dyskinesia in clinical practice and research. The assessment includes both examination of the patient during specific activities and global clinical judgments about the severity and incapacitation caused by the movements. Regular AIMS assessments are often required by regulatory authorities for long-term antipsychotic studies.
Usage
