RELATIONSHIP OF NEUROMUSCULAR PERFORMANCE TO THE BLOOD ALCOHOL CONCENTRATION

The intent of the study was to determine if neuromuscular impairment occurring as blood alcohol concentrations increase or decrease through corresponding ranges of concentrations; and, the effect on neuromusclar control of maintaining peak BAC's. Group A, 11 subjects, were to determine effects of a rapidly changing BAC; Group B, 6 subjects, demonstrated effects of maintaining high BAC after an initial rapid rise. The Koerth type pursuit rotor was the means of measuring motor control. Subjects' reaction time was measured with a modified electronic counter for 30 sequences. All were administered 95% ethanol in an 8:1 concentration with standard D5W intravenously. Stephenson Breathalyzer determined BAC's. All subjects underwent a control session 1 day prior to alcohol infusion. Data shows no definitive correlation between reaction time and motor coordination deterioration during alcohol intoxication. Peak BAC leads to impairment, descent increases reaction time but deteriorates motor coordination. /SRIS/
