The Good • Reliable • Interrater reliability confirmed • Valid • Time efficient • Original trial had a 6 minute average • Cell phone with video capability takes 38 seconds longer than bedside examination
The Bad • Tendency to favor speech/language function over higher integrated sensory function • L MCA infarcts average 4 points higher than R MCA infarcts • Some items represent redundancy • Ataxia with gross motor function • Dysarthria with aphasia • Too often ataxia is over represented
The Ugly • Brainstem/cerebellar function overly minimized • Not a good scale for the “dizzy plus” patient
