Abnormal Involuntary Movement Scale
Psych Ex
Facial and Oral Movements
1. Muscles of facial expression,
e.g., movements of forehead, eyebrows, periorbital area, cheeks.
Include frowning, blinking, grimacing of upper face.
0 1 2 3 4
2. Lips and perioral area,
e.g., puckering, pouting, smacking.
0 1 2 3 4
3. Jaw,
e.g., biting, clenching, chewing, mouth opening, lateral
movement.
0 1 2 3 4
4. Tongue.
Rate only increase in movement both in and out of mouth, not
inability to sustain movement.
0 1 2 3 4
Extremity Movements
5. Upper (arms, wrists, hands, fingers).
Include movements that are choreic (rapid, objectively
purposeless, irregular, spontaneous) or athetoid (slow, irregular,
complex, serpentine). Do not include tremor (repetitive,
regular, rhythmic movements).

squirming, inversion and eversion of foot.

Trunk Movements
7. Neck, shoulders, hips,
e.g., rocking, twisting, squirming, pelvic gyrations. Include
diaphragmatic movements.
0 1 2 3 4
Global Judgments
8. Severity of abnormal movements.
0 1 2 3 4
based on the highest single score on the above items.
9. Incapacitation due to abnormal movements.
0 = none, normal
1 = minimal
2 = mild
3 = moderate
4 = severe
10. Patient’s awareness of abnormal movements.
0 = no awareness
1 = aware, no distress
2 = aware, mild distress
3 = aware, moderate distress
4 = aware, severe distress
Dental Status
11. Current problems with teeth and/or dentures.
0 = no
1 = yes
12. Does patient usually wear dentures?
0 = no
1 = yes
