“…For preventing distal spread and stabilizing stimulation at a specific point, supramaximal stimulation and adequate pressure were applied (4). According to this, five short segments were obtained: first segment: 4 cm distal to the elbow-2 cm distal to the elbow; second segment: 2 cm distal to the elbow-the elbow; third segment: the elbow-2 cm proximal to the elbow; fourth segment: 2 cm proximal to the elbow-4 cm proximal to the elbow; and fifth segment: 4 cm proximal to the elbow-6 cm proximal to the elbow (7).…”

“…In addition, they were retrospectively re-evaluated with reference values that were recently revealed. Based on this evaluation, for latency change, the values above 0.5 msn in the 1 st , 4 th , and 5 th segments; above 0.6 msn in the 2 nd segment; and above 0.7 msn in the 3 rd segment were accepted to be significant (7). For amplitude change, a decrease over 20% was interpreted in favor of focal conduction block, as recommended by the American Association of Neuromuscular and Electrodiagnostic Medicine (13).…”

“…It has played a role in the increase of diagnostic sensitivity (5,6). Latency differences in short segments and reference values of conduction velocity have been revealed in a study conducted recently (7). A detailed electrophysiological examination including SSCS, in patients with UNE can influence the decision of conservative or surgical treatment and the technique of surgical treatment to be applied (8).…”

Objective: The aim of this study was to investigate the localization properties in electrodiagnostically evaluated patients with a prediagnosis of ulnar neuropathy at the elbow. Material and Methods:The results of 57 patients who were electrodiagnostically defined as ulnar neuropathy at the elbow, with using short segment conduction study (SSCS), were evaluated retrospectively. The number of extremities determined as having focal conduction block with changes in latency was 30, while focal conduction alone was 27. The locations of nerve entrapment sites were determined as humeroulnar arcade (HUA), retroepicondylar groove (RTC), medial intermuscular septum (MIS). Results: The entrapment was found in the left upper extremity with a rate of 73%. The frequencies of localizations were determined for RTC (35%), MIS (25%), RTC+MIS (19%), HUA (16%), HUA+RTC (5%). Conclusion:The entrapments at RTC, MIS and HUA regions could be determined in patients whom 10 cm SCSS technique was used. The localizations of ulnar nerve entrapment at the elbow were RTC, MIS and HUA, in the order of decreasing frequency.

New treatment alternatives in the ulnar neuropathy at the elbow: ultrasound and low-level laser therapy

et al. 2014

Ulnar nerve entrapment at the elbow (UNE) is the second most common entrapment neuropathy of the arm. Conservative treatment is the treatment of choice in mild to moderate cases. Elbow splints and avoiding flexion of the involved elbow constitute majority of the conservative treatment; indeed, there is no other non-invasive treatment modality. The aim of this study was to investigate the efficacy of ultrasound (US) and low-level laser therapy (LLLT) in the treatment of UNE to provide an alternative conservative treatment method. A randomized single-blind study was carried out in 32 patients diagnosed with UNE. Short-segment conduction study (SSCS) was performed for the localization of the entrapment site. Patients were randomized into US treatment (frequency of 1 MHz, intensity of 1.5 W/cm(2), continuous mode) and LLLT (0.8 J/cm(2) with 905 nm wavelength), both applied five times a week for 2 weeks. Assessments were performed at baseline, at the end of the treatment, and at the first and third months by visual analog scale, hand grip strength, semmes weinstein monofilament test, latency change at SSCS, and patient satisfaction scale. Both treatment groups had significant improvements on clinical and electrophysiological parameters (p < 0.05) at first month with no statistically significant difference between them. Improvements in all parameters were sustained at the third month for the US group, while only changes in grip strength and latency were significant for the LLLT group at third month. The present study demonstrated that both US and LLLT provided improvements in clinical and electrophysiological parameters and have a satisfying short-term effectiveness in the treatment of UNE.

Reference data for ulnar nerve short segment conduction studies at the elbow

Abstract: Reference values should be determined separately over each 2-cm segment, and the effect of BMI should be considered when interpreting SSCSs.
