AIMS

Clinical Scales

The AIMS is used to detect tardive dyskinesia (TD) in patients who are treated with neuroleptic medications as well as to follow the severity of TD over time.

It is a 12-item clinician administered and scored scale. Items 1 through 10 are rated on a 5-point scale and assess orofacial movements, extremity and truncal dyskinesia, and global severity. Items 11 and 12 are yes-no questions that assess dental status.

You can also download a printable version, examination procedure instructions, instructional video, or continue with the Abnormal Involuntary Movement Scale.

Examination Procedure

Either before or after completing the Examination Procedure, observe the patient unobtrusively at rest (eg, in waiting room).

The chair to be used in this examination should be a hard, firm one without arms.

1:Ask patient whether there is anything in his/her mouth (ie, gum, candy, etc) and if there is, to remove it.

2:Ask patient about the current condition of his/her teeth. Ask patient if he/she wears dentures. Do teeth or dentures bother patient now?

3:Ask patient whether he/she notices any movements in mouth, face, hands, or feet. If yes, ask to describe and to what extent they currently bother patient or interfere with his/her activities.

4:Have patient sit in chair with hands on knees, legs slightly apart, and feet flat on floor. (Look at entire body for movements while in this position).

5:Ask patient to sit with hands hanging unsupported. If male, between legs, if female, and wearing a dress, hanging over knees. (Observe hands and other body areas.)

6:Ask patient to open mouth. (Observe tongue at rest within mouth.) Do this twice.

7:Ask patient to protrude tongue. (Observe abnormalities of tongue movement.)

8:Ask patient to tap thumb, with each finger, as rapidly as possible for 10-15 seconds: separately with right hand, then with left hand. (Observe facial and leg movements.)

9:Flex and extend patient's left and right arms, one at a time. (Note any rigidity and rate it.)

10:Ask patient to stand up. (Observe in profile. Observe all body areas again, hips included.)

11:Ask patient to extend both arms outstretched in front with palms down. (Observe trunk, legs, and mouth.)

12:Have patient walk a few paces, turn, and walk back to chair. (Observe hands and gait.) Do this twice.
