Delayed effects of acute alcoholic intoxication were kinesiologically studied. Changes in eye-hand coordination, manipulative skills, and postural responses were objectively measured by utilizing the apparatus and techniques designed and constructed at the Division of Biomechanics of New York University.

Nine healthy males were tested with various amounts of alcoholic beverages on several days in a simulated social setting.

Effects of intoxication, sometimes lasting as long as 20 hours after ingestion of alcohol were found. These included decreased motor/sensory skill, prolonged reaction time and poor motor performance. Without tactile and/or visual facilitation manipulative and position skills were also impaired. Further, there was limitation in visual scanning and deterioration in postural control in some cases.

Recognition of post intoxication hazard in industrial and traffic safety is stressed.
