Value of MUNE versus compound muscle action potential in assessing motor unit loss in patients with carpal tunnel syndrome

Table 5 Sensitivity and specificity of MUNE methods and median nerve motor amplitude in detecting motor unit loss of patients with CTS

Variable	AUC	Sens.	Spec.	95% CI		Cutoff value	p-value
Variable	AUC	Sens.	Spec.	Upper bond	Lower bond	Cutoff value	p-value
Motor amplitude, mV	0.706	61%	63%	0.633	0.780	6.85	< 0.001
MUNE method
Incremental	0.875	84%	82%	0.824	0.926	160.5	< 0.001
aMPS	0.886	81%	80%	0.838	0.935	203	< 0.001

AUC area under the curve; Sens. = sensitivity; Spec. = specificity; MUNE = motor unit number estimation; aMPS = adapted multipoint stimulation. (Median nerve stimulation and recording from the APB muscle.)
