A study sought to determine if the Abnormal Involuntary Movement Scale (AIMS), which relies on visual judgements, can be a reliable measurement tool through video chat. AIMS scores were examined by 2 independent raters in face-to-face contact and 2 raters assessing remotely through audio-visual transmission. Intraclass Correlation Coefficient was used to determine inter-rater reliabilities. No considerable difference was found between the raters, which may be due to the condition while examining involuntary movements using the AIMS. Researchers noted that the results were dependable to the same degree.
