Background & Aims: Lower limbs’ nerves are exposed to mechanical injuries in athletes (e.g. football players), because of the excessive physical demand of their job. The objective of the present study was to evaluate the influence of regular and intense sports, such as football, on nerves in the lower leg. This study was conducted during 2006 to 2007 in the Shiraz Rehabilitation Faculty, Univer...

The near-nerve sensory nerve conduction in the medial and lateral plantar nerves was studied in 25 cases of tarsal tunnel syndrome. Sensory nerve conduction was abnormal in 24 cases (96%) The most common abnormalities were slow nerve conduction velocities and dispersion phenomenon (prolonged duration of compound nerve action potentials). These two electrophysiological abnormalities are indicati...

Acute experimental allergic neuritis was induced in Lewis rats by inoculation with bovine intradural root myelin and adjuvants. In terminal experiments, sensory conduction was assessed in rats with hindlimb ataxia and weakness by stimulating the exposed sciatic nerve and recording directly from the exposed L-4 spinal nerve, dorsal root ganglion, dorsal root, and dorsal root entry zone. Focal co...

background: the use of organophosphates (ops) in developing countries is rising in large quantities and non-secure methods. this problem not only causes acute poisoning but also may lead to chronic diseases such as polyneuropathy. in iran, 60% of pesticides are organophosphate compounds that may lead to delayed polyneuropathy. objectives: the purpose of the current study was to evaluate delayed...

The cochlear implant, a microelectrode array that directly stimulates the auditory nerve, has greatly benefited many individuals with profound deafness. Deaf patients without an intact auditory nerve may be helped by the next generation of auditory prostheses: surface or penetrating auditory brainstem implants that bypass the auditory nerve and directly stimulate auditory processing centers in ...

Peripheral nervous system abnormalities, including neuropathy, have been reported in people with cystic fibrosis. These abnormalities have largely been attributed to secondary manifestations of the disease. We tested the hypothesis that disruption of the cystic fibrosis transmembrane conductance regulator (CFTR) gene directly influences nervous system function by studying newborn CFTR(-/-) pigs...

Introduction: Ischaemic-reperfusion nerve injury has been suggested as the mechanism for post-tourniquet limb paralysis. As dexamethasone (Dex) has been shown to Prevent ischaemic-reperfusion process in some tissues, we tested the hypothesis that this drug would reduce tourniquet induced nerve injury. Methods: 36 male Wistar rats (200-250 gr) were chosen and divided randomly into 6 equal grou...

Sound pressure levels in the external auditory canals of 50 subjects were measured at 2000 and 4000 Hz with a bone-conduction vibrator on the forehead, the mastoid ipsilateral to the probe microphone, and the mastoid contralateral to the probe microphone. A plug was placed in the external auditory canal to minimize sound pressure levels in the external auditory canal produced by the osseotympan...

BACKGROUND Conventional methods in the diagnosis of carpal tunnel syndrome (CTS) in patients with polyneuropathy (PNP) are insufficient. AIMS We suggest that the comparison of the conduction of the median nerve with that of the neighboring peripheral nerves may be more beneficial in the diagnosis of entrapment neuropathy. SETTING AND DESIGN The median nerve sensory conduction in healthy vol...

The objective of this study was to determine direct measurements of auditory pathways by magnetic resonance imaging (MRI) during the growth period of healthy Beagles, and to discover how canine brainstem auditory evoked response (BAER) latencies vary in relation to these MRI measurements. Eighty healthy Beagles were tested at eight, 16 and 52 weeks of age (stages 1, 2, 3, respectively) with BAE...
