Clinical NST for trigeminal neuropathy^{^a}


	Level A: Spatiotemporal Sensory Perception Direction Sensitivity <90% Static 2-Point Discrimination <18 mm	Level B: Contact Detection with Monofilament <2.83	Level C: Pain Threshold and Tolerance Heat Temperature Threshold <47 Heat Temperature Tolerance <50 Pressure Pain Threshold <1.5 lb. Pressure Pain Tolerance <2.0 lb.
Normal	Present	Present	Present
Mild	Failed	Present	Present
Moderate	Failed	Failed	Present
Severe	Failed	Failed	Elevated
Complete	Failed	Failed	Absent

↵a Present: values recorded at test and control sites exhibit comparable sensitivity within published normative range. Failed: values recorded at test site sensitivity are less than that of control sites or published normative range. Elevated: values recorded at test site sensitivity are greater than that of control sites or published normative range but below maximum of test device (ie, 6 lbs.). Absent: values recorded at test site sensitivity are greater that maximum of test device (ie, 6 lbs.).
