ABSTRACT

In this study, 125 healthy people and 177 patients from various disease groups were accepted in order to determine the normal sensory conduction data of superficial radial nerve of our own laboratory and the diagnostic value of this nerve conduction study in the various diseases.

We found that the latency, amplitude and conduction velocity of superficial radial nerve in the healthy group are 1.68 ± 0.18 msc, 30.7 ± 11.2 μV and 52.2 ± 4.3 m/sc respectively.

Abnormality values of superficial radial nerve conduction in the hereditery motor sensory neuropathies, lesions of radial nerve, total brachial pleksopathies, unidentified type sensorymotor polineuropathies, diabetic mononeuropathy multipleks and diabetic sensorymotor polineuropathies were 100, 89.5, 57.1, 23.1, 20 and 16.7 per cent respectively. Conduction study was normal in the partial lesions of brachial plexus, lesions of the deep brunch of radial nerve, radial nerve entrapments at the spiral groove, myopathies, motor neuron diseases, carpal tunnel syndromes and ulnar nerve entrapments at the elbow. We concluded that to perform the sensory conduction study of superficial radial nerve is easy and may provide help especially for the diagnosis of the first three diseases mentioned above.
