Simplified Motor Score (SMS)

Description

Calculates the Simplified Motor Score (SMS), a streamlined version of the Glasgow Coma Scale (GCS) that uses only the motor component to predict outcomes in traumatic brain injury. It has been shown to have similar diagnostic accuracy to the full GCS for predicting intubation, neurosurgical intervention, and mortality.

Usage

simplified_motor_score(motor_response)

Arguments

motor_response

Numeric. The patient's best motor response. 2: Obeys commands. 1: Localizes pain. 0: Withdraws to pain or worse (Flexion, Extension, or None).

Value

A list containing:

SMS_Score	The input score (0-2).
Risk_Classification	Assessment of TBI severity risk (Low vs. High).

Examples

# Example 1: Patient obeys commands
# Score = 2 (Low Risk)
simplified_motor_score(2)

# Example 2: Patient only localizes pain
# Score = 1 (High Risk)
simplified_motor_score(1)

# Example 3: Decerebrate posturing (Extension)
# Score = 0 (High Risk)
simplified_motor_score(0)
