Fig. 3From: Role of superficial peroneal sensory potential and high-resolution ultrasonography in confirmation of common peroneal mononeuropathy at the fibular neckSensitivity and specificity of superficial peroneal sensory potential (SPSP) and high resolution ultrasonography in confirmation of common peroneal neuropathy at the fibular neck.Test 1: Increased high-resolution ultrasonography cross-sectional area (HRUS- CSA) of the common peroneal nerve at the fibular neck (> 11mm2) plus superficial peroneal sensory nerve (SPSP) affection versus the electrophysiological evidence of common peroneal motor neuropathy at fibular the neck.Test 2: Increased HRUS-CSA of the common peroneal nerve at the fibular neck (> 11mm2) versus the electrophysiological evidence of common peroneal motor neuropathy at the fibular neckBack to article page
