“…However, this may not be present in all cases. In one large series, conduction block was demonstrable only in 33% of 91 cases [7]. Segmental demyelination, axonal damage or both processes may be present.…”

“…A differential diagnosis for RNE includes extensor tendinitis and lateral epicondylitis (which can coexist with RNE), neuralgic amyotrophy, brachial plexopathy, or cervical radiculopathy. 18,19 ESTABLISHING WORK RELATEDNESS Work-related activities may cause or contribute to the development of PMNE/RNE. Establishing work relatedness requires all of the following:…”

“…For patients having weak elbow extension, wrist drop or finger drop, electrophysiological evaluation of the radial nerve helps the physician to localize the lesion, assess the underlying pathophysiology, and provide useful information to the patient [1234]. Despite its clinical significance, radial motor NCS is a difficult procedure, even for a skilled electromyographer, since the placement of recording electrodes is technically more difficult than it is for median or ulnar nerves.…”

“…However, the type of recording electrode (needle or surface) and placement sites (such as EIP, brachioradialis and extensor digitorum communis muscles) differ among the various researchers. Additionally, there are no standardized methods and reference values of compound muscle action potential (CMAP) amplitude for radial nerve, with values varying from 2 to 5 mV [1234589]. …”

ObjectiveTo obtain reference values, to suggest optimal recording and stimulation site for radial motor nerve conduction study (RmNCS), and to analyze the correlation among RmNCS parameters, demographics and ultrasonography (US) findings.MethodsA total of 55 volunteers participated in this study. We hypothesized that ‘lateral edge of spiral groove (A)’ was the optimal stimulation site, and the ‘largest cross-sectional area (CSA) of extensor indicis proprius (EIP) muscle (B)’ was the optimal recording site. The surface distance between ‘A’ and the lateral epicondyle of the humerus divided by upper arm length, was named the spiral groove ratio. The surface distance between ‘B’ and the ulnar styloid process divided by forearm length, was named the EIP ratio. Using US, we identified these sites, and further conducted RmNCS.ResultsData was collected from 100 arms of the 55 volunteers. Mean amplitude and latency were 5.7±1.1 mV and 5.7±0.5 ms, respectively, at the spiral groove, and velocity between elbow and spiral groove was 73.7±7.0 m/s. RmNCS parameters correlated significantly with height, weight, arm length, and CSA of the EIP muscle. Spiral groove ratio and EIP ratio were 0.338±0.03 and 0.201±0.03, respectively; both values were almost the same, regardless of age, sex and handedness.ConclusionWe established a reference value and standardized method of RmNCS using US. Optimal RmNCS can be conducted by placing the recording electrode 20% (about one-fifth) of forearm length from the ulnar styloid process, and stimulating at 34% (about one-third) of the humeral length from the lateral epicondyle.
