background: two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (op) and abductor pollicis brevis (apb). however, riché-cannieu communicating branch (rccb) may limit the use of these muscles in electrodiagnosis. this condition is confusing in the case of median nerve injuries. this study was conducted to evaluate the prevalence of rccb.   methods: ...

BACKGROUND Numerous nerve conduction tests are used for the electrodiagnosis of carpal tunnel syndrome (CTS), with a wide range of sensitivity and specificity reported for each test in clinical studies. The tests have not been assessed in population-based studies. Such information would be important when using electrodiagnosis in epidemiologic research. The purpose of this study was to compare ...

Dear Editor, We have read with great attention the paper by Fernandes and colleagues about electrodiagnosis as a monitoring tool in ulnar nerve recovery after surgical treatment of nerve lesion1. The study is very interesting and aims to demonstrate that, among the electrodiagnostic parameters, Chronaxie may be the one that best detects the evolution of neuromuscular responses in ulnar nerve re...

L)UCHENNE of Bouiogne nearly one hundred years ago realised that in order to understand and treat muscle disease the clinician must himself be conversant with pathology and electrodiagnosis. Many of the diseases of muscle classified by the nineteenth-century neurologists remain mysterious in all but the name, similar then as now. Yet exciting advances in the basic problems of muscle disorders h...

BACKGROUND F waves are late electrophysiological responses to antidromic activation of motor neurons and are used to evaluate the conduction along the whole length of peripheral nerves. We aimed to determine the diagnostic efficacies of minimum median nerve F-wave latency (FWL) and median-to-ulnar nerve F-wave latency difference (FWLD) on carpal tunnel syndrome (CTS). MATERIALS AND METHODS Th...

Zurich where he became 'privat-dozent' for neurology, the first appointment of its kind in Switzerland. The following year in a borrowed room in the Pathological Institute, von Monakow assisted by a young American zoologist, Henry Donaldson, established the laboratory which was to become the Hirnanatomisches Institute. Von Monakow developed a very active private practice, first as a general phy...

This study was done to assess the percentage of abnormality in additional nerve conduction techniques after normal median distal latency (routine) in mild carpal tunnel syndrome (CTS). Bilateral nerve conduction studies were carried out in 116 consecutive symptomatic CTS patients (153 hands). Mild cases were based on normal routine (< 3.7 ms, peak-measured, 14 cm) and at least one technique abn...

Worldwide concern over Zika virus causing Guillain-Barre syndrome (GBS) soared after recent reports that Zika-related weakness was due to GBS. A global strategic response plan was initiated with recommendations for at-risk countries to prepare for GBS. This plan has major economic implications, as nations with limited resources struggle to implement costly immunotherapy. Since confirmation of c...
