Factors influencing aversion to specific electrodiagnostic studies

Factors influencing aversion to specific electrodiagnostic studies

OBJECTIVE To compare the degree of discomfort caused by nerve conduction studies (NCS) versus needle electromyography (EMG), and to determine what factors predict aversion to one test or the other. METHODS Two hundred patients underwent both EMG and NCS, and were asked to indicate which test was more uncomfortable. Responses were then correlated with demographic information, testing character...

Electrodiagnostic studies.

This article overviews electrodiagnostic tests that provide evidence-based data in the treatment and management of abnormalities in nerves and muscles. There is a focused review on cardiac tests, nerve-conduction tests, low-back pain tests, seizure and epilepsy tests, and obstructive sleep apnea electrodiagnostic tests. Case reports demonstrate how these electrophysiologic tests can provide spe...

Studies on factors influencing enzyme responses to adenylate energy charge.

The responses of rat brain hexokinase, human red cell hexokinase, and human red cell pyruvate kinase to changes in the adenylate energy charge were observed. A number of factors were found to be capable of altering these responses. These include the concentration of total adenylates, the level of free uncomplexed Mg2+, the kinetic reaction mechanism of the enzyme under study, and the concentrat...

Studies on the epidemiology of Escherichia coli infections. V. Factors influencing acquisition of specific serologic groups.

Stool carrier rates of Escherichia coli serogroups 4, 6, and 75 were determined on admission and discharge for 190 patients. Persons who were in the hospital 3 weeks or longer had an intestinal carrier rate of 46% compared to a rate of 28% in individuals who had no recent hospital contact. Treatment with broad spectrum antibiotics increased the susceptibility for acquisition of certain specific...
