Electrodiagnosis in Diabetic Neuropathy

Dx a diagnostic procedure which Econsists of a series of tests employed for the diagnosis of neuromuscular diseases. These tests must be conducted by a physician trained in electrodiagnostic medicine as they are customised according to the presenting clinical problem, sequentially done, collectively interpreted and then correlated with the clinical features to arrive at a diagnosis that explains the neuromuscular disease. It is the only procedure that evaluates the function of the lower motor & sensory neuron. Multiple tests can be performed depending on the disease, but below given are a few with relation to the diagnosis of diabetic neuropathies. EDx tests lNerve conduction studies: sensory and motor lF wave studies lH reflex studies lN e e d l e e l e c t r o m y o g r a p h i c examination (NEE or EMG) lHeart rate variability test lSympathetic skin response Terminology in Electrodiagnosis lClinical neurophysiology includes EDx, EEG and Evoked potential testing lElectrodiagnosis (EDx) aka neuroelectrodiagnosis lElectroneuromyography (ENMG) is synonymous with EDx and is the preferred term (as there cardioelectrodiagnosis as well) lNCS is nerve conduction studies lEMG is electromyography also known as needle electromyography lAn Electromyographer is the physician conducting the procedure: the Electrodiagnostician lAn Electromyograph is the equipment Fig. 1
