Simplified Motor Scales (SMS) refer to a neurological evaluation that is designed to provide a meaningful, objective prognostic evaluation of an individual. SMS have been proposed as alternatives that would improve upon the Glasgow Coma Scale challenges of being confusing, unreliable, and unnecessarily complex.
An example of a SMS can be remembered by the abbreviation TROLL - Test Responses: Obeys, Localizes, or Less.
