Because patients may suppress movements when they concentrate, it is suggested that the patient performs additional tasks during the AIMS assessment. Doing so may stimulate the patient and provoke the appearance of movement disorders. For example, during administration of item 5 of the AIMS assessment, first observe the patient while they sit in a chair with hands on knees and feet flat on the floor and continue to observe them after requesting that they count backward from 30. During assessment of this same item, ask the patient to sit with their hands hanging unsupported (eg, between their legs or over their knees) and ask them to describe their travel route to the appointment.
