Normal Flexion - Bends arm at elbow rapidly but features not predominantly abnormal (+4).Abnormal flexion - Bends arm at elbow, features clearly predominantly abnormal (+3).None - No movement in arms/legs, no interfering factor (+1).Non-testable - Paralysed or other limiting factor (NT).Oriented - Correctly gives name, place, and date (+5).Confused - Not orientated but communicates coherently (+4).None - No audible response, no interfering factor (+1).Non-testable - Factor interfering with communication (NT).To Pressure - After fingertip stimulus (+2).None - No opening at any time, no interfering factor (+1).The Glasgow Coma Scale analyzes patients on three different criteria:Įach criterion is on a different scale with a total possible score of 15.
