“…This finding met with the finding of [7]. Also, this is in keeping with the observations by two other previous studies [18,7]. They found that if the prominent hallmark of CPN lesion is an axonal loss, abnormalities in superficial peroneal sensory potential will mirror axonal affection in motor nerves.…”

“…These findings met with the findings of [7], who reported that axonal loss and selective fascicular involvement commonly occurs in common peroneal mononeuropathies. Specifically, deep peroneal nerve fibers are more commonly affected, and superficial peroneal sensory fibers are often spared in CPN with predominantly demyelinating lesions, whereas in axonal lesions, the impairment of both branches correlates more closely.…”

“…A loss in amplitude of this response implies some axonal loss affecting either the common peroneal nerve or its superficial branch [5]. Prominent axonal loss is the hallmark of most CPN lesions and suggested that abnormalities in sensory nerves mirror those in motor nerves [7].…”

Background: Common peroneal mononeuropathy at the fibular neck (CPN) is one of the most frequent neuropathies of the lower extremities. Nerve conduction studies (NCS) have been used to confirm the diagnosis of CPN and localize common peroneal nerve abnormalities. High-resolution ultrasonography (HRUS) can aid in assessing the size of the common peroneal nerve. Aim: Was to evaluate the superficial peroneal sensory potential (SPSP) and HRUS role in the confirmation of CPN. Methods: This study was conducted on 70 patients presented with clinical and motor electrophysiological evidence of common peroneal neuropathy at the fibular neck and 70 controls. Clinical assessment, electrophysiological evaluations, and HRUS at the fibular neck were done. Results: All the patients were electrophysiologically proven to have common peroneal motor neuropathy at the fibular neck, and seven of them showed abnormalities in nerve conduction studies only. The patients showed smaller common peroneal nerve motor and sensory responses and much larger cross-sectional area (CSA) of the common peroneal nerve at the fibular neck when compared with the controls. NCS and EMG positive findings are the most significant factor related to the increased HRUS CSA. Affected SPSP is significantly detected in patients with axonal affection. CSA of common peroneal nerve at the fibular neck showed a significant positive correlation with body mass index, motor, and sensory latencies. Also, it showed a significant negative correlation with motor and sensory amplitudes. HRUS CSA localized the lesion at the fibular neck with sensitivity and specificity 83% and 53% respectively. CSA plus SPSP affection sensitivity and specificity in confirming CPN were 91.9% and 89%. Conclusion: HRUS CSA plus affected SPSP improve the diagnosis of CPN compared to standard electrophysiological criteria. Recommendation: Further studies on a wider scale for detection of their role in the prediction of prognosis in CPN.

“…This calculation has been used in adult [14][15][16] and pediatric studies. 17,18 F responses were recorded infrequently due to patient discomfort in the pediatric age range. Antidromic sensory nerve conduction studies of the radial to the snuffbox were obtained, with contralateral studies recorded when tolerated.…”

Nerve conduction studies and needle electromyography, collectively known as electrodiagnostic (EDX) studies, have been available for pediatric patients for decades, but the accessibility of this diagnostic modality and the approach to testing vary significantly depending on the physician and institution. The maturation of molecular diagnostic approaches and other diagnostic technologies such as neuromuscular ultrasound indicate that an analysis of current needs and practices for EDX studies in the pediatric population is warranted. The American Association of Neuromuscular & Electrodiagnostic Medicine convened a consensus panel to perform literature searches, share collective experiences, and develop a consensus statement. The panel found that electrodiagnostic studies continue to have high utility for the diagnosis of numerous childhood neuromuscular disorders, and that standardized approaches along with the use of high-quality reference values are important to maximize the diagnostic yield of these tests in infants, children, and adolescents.
