The influence of one-sided limb dominance on the muscles, bones and motor conduction velocity of median nerve has been investigated and reported. We have undertaken a more detailed study of the conduction velocity of the efferent fibres of median and ulnar nerves of both sides in 25 right-handed and an equal number of left-handed subjects of both sexes in the age group of 18-30 years. A signifi...

Sensory conduction was studied in six patients with chronic sensory ataxic neuropathy of an idiopathic type and associated with Sjögren's syndrome. Motor nerve conduction velocities were normal in most cases, but sensory nerve potentials could not be evoked in a routine peripheral nerve conduction study. Cortical and cervical somatosensory evoked potentials (SEPs) and evoked potentials from Erb...

INTRODUCTION This study focuses on an anatomic variation in which the lateral antebrachial cutaneous nerve (LACN) innervates the radial border of the dorsum of the hand and thumb in addition to, or replacing, the superficial radial nerve (RSN). Here, we propose a technique of nerve conduction that identifies this variation. METHODS We studied nerve conduction in 200 upper limbs of two series ...

Background: This study aimed at understanding thermal effects on nerve conduction and developing new methods to produce a reversible thermal block of axonal conduction in mammalian myelinated nerves. Methods: In 13 cats, conduction block of pudendal nerves by cooling (5–30 °C) or heating (42–54 °C) a small segment of the nerve was monitored by the urethral striated muscle contractions and incre...

Background: Few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. Case Presentation: A 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. At ulrasonographic examination, a simple cyst was detected. Sensory response of palmar cutaneous branch of median nerve was absent at the affec...

In the carpal tunnel syndrome median nerve motor conduction may be delayed below the wrist, while the motor nerve fibre conduction velocity above-the wrist may be relatively unaffected (Carpendale, 1956; Simpson, 1956). Median nerve sensory conduction may also be impaired below the wrist in the carpal tunnel syndrome (Gilliatt and Sears, 1958). No detailed study has been made comparing distal s...
