involvement of the peripheral nervous system is one of the complications of multiple myeloma with a varying incidence of clinical and subclinical neuropathy in different studies. as most of the patients with multiple myeloma suffer from generalized systemic symptoms such as malaise, bone and low back pain, the clinical clues to the diagnosis of the neuropathy in its initial stages could be igno...

OBJECTIVE To establish nerve conduction parameters for carpal tunnel syndrome (CTS) electrodiagnosis in the elderly. METHOD Thirty healthy subjects (65-86 years), 9 male and 21 female, were studied. Routine median and ulnar sensory and motor nerve conduction studies, median mixed palmar latency, comparative latency techniques median to ulnar (sensory, mixed and motor lumbrical-interossei), me...

Temperature is an important and common variable that modifies nerve conduction study parameters in practice. Here we compare the effect of cooling on the mixed palmar median to ulnar negative peak-latency difference (PMU) in electrodiagnosis of carpal tunnel syndrome (CTS). Controls were 22 subjects (19 women, mean age 42.1 years, 44 hands). Patients were diagnosed with mild symptomatic CTS (25...

INTRODUCTION The second lumbrical-interossei latency difference test (2LINT) is used frequently for electrodiagnosis of carpal tunnel syndrome (CTS). A premotor potential observed with 2LINT has been identified as a median-nerve sensory nerve action potential. We evaluated the utility of the premotor potential latency analysis (i.e., premotor potential study; PPS) for CTS electrodiagnosis. ME...

objective this study aims at determining the epidemiologic, presenting symptoms, clinical course and electrophysiologic features of childhood guillain-barre syndrome (gbs) in the east azarbaijan province over a period of five years. materials & methods  all the patients, aged< 15 years, referred/admitted to tabriz children hospital with gbs between january 2001 and december 2005 were investigat...

Lesions of the anterior interosseous nerve in the forearm are rare and often misdiagnosed as tendon injuries. A consecutive series of 13 patients with this condition referred for electrodiagnosis is reviewed. Only three had originally a correct clinical diagnosis and three were initially considered to have tendon ruptures. Five cases were of mechanical origin and seven due to 'neuritis'. All sh...

determination of f-wave latency is a simple and valuable method in evaluating proximal part of peripheral nerves. the aim of this study was to determine the mean minimal peroneal f wave (f min) in healthy individuals. a total of 282 individuals were studied. the mean age was 45.6 years. the f min (± sd) for 564 peroneal nerves was 47.09 ± 4.51 ms. the f min for the age group of 20-45 and height...

background : determining the validity of current median sensory nerve conduction techniques for diagnosis of carpal tunnel syndrome (cts). methods: eighty five patients with clinical diagnosis of cts were compared with the same number of healthy people. the validity of electrodiagnostic tests were compared in a case-control manner. these electrodiagnostictechniques included long-segment, short-...
