Abnormal Involuntary Movement Scale (AIMS) Form PDF Details

The Abnormal Involuntary Movement Scale (AIMS) rates the severity of 14 types of involuntary movements in patients receiving antipsychotic medications. It evaluates movements across four body regions: facial (muscles around the eyes, lips, and lower face), oral (tongue, jaw, and lips), extremities (arms, wrists, hands, fingers, legs, knees, and toes), and trunk (neck, shoulders, and hips). Each area receives a score of 0 (no abnormal movement) to 4 (severe involuntary movement).

Clinicians use the AIMS form to screen for tardive dyskinesia (TD), a potentially irreversible movement disorder that can develop after long-term antipsychotic use. The American Psychiatric Association recommends a baseline AIMS assessment before starting antipsychotic therapy and follow-up assessments every 3 to 6 months. For patients with other movement disorders, the Toronto Western Spasmodic Torticollis Rating Scale provides a specialized tool for assessing cervical dystonia.

The form also includes a dental status section covering denture use, edentulous areas, and jaw problems, since oral conditions can affect the appearance of facial and oral movements during evaluation. For patients with broader functional limitations, clinicians often pair AIMS assessments with the Functional Movement Screen or the Lower Extremity Functional Scale to obtain a complete picture of movement capacity.

Stage number 1 in filling out aims assessment

2. After completing the first section, insert the required details in the extremity movement fields: lateral movement, tongue rate, upper arm and wrist movements, lower leg and knee movements, and trunk movements including neck, shoulder, and hip areas. Also complete the Global Judgments section covering the severity of abnormal movements and the patient's awareness of those movements.

Tips on how to complete aims assessment portion 2

Take care to review the severity of abnormal movements section before finalizing, as errors here are the most common mistake when completing the AIMS form.

3. In this final step, fill out the dental status fields: current problems with teeth or dentures, whether dentures are usually worn, edentulous status, and whether movements disappear during sleep. Mark each Yes or No response carefully.
