BACKGROUND It is well known that reducing tissue temperature changes sensory and motor nerve conduction. However, few studies have compared the effect of different cold modalities on nerve conduction parameters. OBJECTIVE The purpose of this study was to compare the effects of ice pack, ice massage, and cold water immersion on the conduction parameters of the sural (sensorial) and tibial moto...

Obese individuals have slowed conduction in the median nerve across the wrist, but the mechanism for this is not established. This case-control study of 27 obese subjects and 16 thin subjects was designed to test the hypothesis that obese individuals have higher carpal canal pressures and more median nerve swelling than thin individuals. All subjects were asymptomatic for hand symptoms, and had...

Data by E. A. Blair and Erlanger on the voltage-capacity curves and the nerve impulse velocities of each of several fibres in the same nerve trunk are related to Rashevsky's equation for the velocity of transmission in nerve. The results lend support to Rashevsky's analysis. Other empirical relations between the velocity and the parameters of the excitation equations indicate the correctness of...

Serial electrophysiological studies were performed in a case of 'tourniquet paralysis' of the upper limb after the application of an Esmarch bandage above the elbow. Three months after onset of paralysis, nerve conduction was reduced to a quarter of normal between elbow and and axilla along the few fibres still conducting through the lesion, but was normal distal to the block. Seven months afte...

The present study examines the reliability of masked high-frequency bone-conduction threshold measurements in 95 normal-hearing subjects. High-frequency pure-tone air-and bone-conduction thresholds were measured with a dedicated laboratory high-frequency auditory evaluation system using matched, modified Koss Pro/4X Plus earphones, and the Pracitronic KH 70/5 bone vibrator. A 400-Hz wide band m...

cochlear nerve (cn) aplasia refers to the absence of a visible cn on oblique sagittal magnetic resonance images of the lateral aspect of the inner auditory canal (iac). magnetic resonance (mr) is the preferred technique in patients with sensorineural hearing loss and/or vertigo; however, computed tomography (ct) is used to evaluate the iac or facial nerve canal. three types of aplasia or hypopl...

In the short-fibered non-striated probascis retractor of phascolosoma (Golfingia gouldii) , 3 conduction is entirely by intrinsic nerve fibers. Evidence for nerve conduction is: velocity of propagation (1.3 and 0.3 m/second for fast and slow responses, respectively), abundance of nerve fibers, block by nerve-blocking drugs, failure of propagation after nerve degeneration, and detection of nerve...

Human and veterinary scientific researchers widely use rats as experimental animals. The rat nerves conduction studies are used for investigations of neural tissue injury, neural regeneration, peripheral neuropathies etc. in experimental models. Nerve conduction studies on animals do not follow strict rules, as studies in humans. Various methods and lack of the single recognized technique of ne...
