Answer

Answer

Another system for assessing TBI severity is the Simplified Motor Score (SMS). The SMS is a 3-point scale developed to address the perceived limitations of the GCS, such as its complexity and poor interrater reliability.

Best Motor Response

0

Withdraws to pain or worse

1

Localizes pain

2

Obeys commands

 

A study by Thompson et al determined that in an out-of-hospital setting, the SMS was similar to the GCS score for predicting TBI outcomes. [26]
