MOTOR NERVE CONDUCTION VELOCITY IN DIABETES

Archives of Neurology, 1961
Introduction Involvement of the peripheral nervous system in diabetes is well known to internists and neurologists. The relation of the neuropathy to the severity, duration, and control of the diabetes is not consistent, and variations in the clinical picture have led to multiple classifications.

Conduction velocity costs energy

Neurocomputing, 2005
Hodgkin and Adrian's 1975 hypothesis that the squid axon is optimized for maximum conduction velocity is flawed by (i) the inaccurate value of its prediction for channel density, and (ii) the prohibitive energetic expense entailed by their prediction. Here we investigate the metabolic cost of conduction velocity.

Sensory group la proximal conduction velocity

Muscle & Nerve, 1984
AbstractThe fastest median and ulnar velocities derived by recording motor and mixed nerve action potentials, F waves, H‐reflexes, and somatosensory evoked potentials (SEPs) were compared. H‐reflex recording was facilitated by employing selective group la excitation during voluntary muscular contraction.

Axonal conduction velocity and perikaryal size

Experimental Neurology, 1975
Abstract The recent identification of brisk-transient units with alpha cells in the cat's retina provided a direct opportunity to test the widely held belief that larger cells give rise to larger axons, and smaller to smaller. Alpha-cell perikarya increase substantially in size over the first 2 mm from the center of the area centralis.

Ultrasound and Conduction Velocity

Physical Therapy, 1984
To the Editor: I commend the educational practice of schools that encourage and support simple research projects by students. The experience of identifying a problem, designing an appropriate experiment to study it, performing the experiment, gathering and analzying the data, and finally reporting the results in a logical and scholarly manner, all ...

Spinal sympathetic conduction velocity in humans

Journal of the Autonomic Nervous System, 1988
Simultaneous micro-electrode recordings of muscle sympathetic activity were made in the radial nerve at the mid-humerus level and the peroneal nerve at the fibular head in 8 healthy subjects. Sympathetic impulses occurred spontaneously in multi-unit bursts time-locked to the cardiac rhythm.

Nerve Conduction Velocity-Reply

JAMA, 1961
To the Editor:— Dr. Hodes' premise is that the conduction velocity of motor fibers in poliomyelitis patients is reduced, presumably because of selective destruction of large motor neurons. This premise was based on determinations in 26 chronic patients (presumptive diagnosis).

Polarity Correlator for Conduction Velocity Measurement

IEEE Transactions on Biomedical Engineering, 1984
Techniques for the estimation of skeletal muscle fiber conduction velocity are of considerable interest. These techniques use, in general, some form of cross correlation or zero-crossing analysis. Cross correlation is a straightforward method of conduction velocity estimation, however, it is difficult to realize low-cost real-time processors.

Ratio of Motor Nerve Conduction Velocity to F-Wave Conduction Velocity in Diabetic Neuropathy

Diabetes Care, 1998
OBJECTIVE To investigate the usefulness of a new parameter, the ratio of motor nerve conduction velocity to F-wave conduction velocity (M/F ratio), for the differential diagnosis of diabetic neuropathy. RESEARCH DESIGN AND METHODS Nerve conduction ...

Diurnal fluctuations of human nerve conduction velocity

Acta Neurologica Scandinavica, 2009
In 14 normal subjects, sensory conduction velocity (SCV), determined at constant skin temperature, displayed diurnal fluctuations which were related to similar variations in rectal temperature. Control of surface limb temperature in routine EMG does not completely obviate the variations induced by the body temperature cycle. Diurnal fluctuations should
