A Standard Psychophysiological Preparation for Evaluating the Effects of Environmental Vibration Stress. Phase II. Implementation

A Standard Psychophysiological Preparation (SPP) for the evaluation of the physiological and biomechanical mechanisms responsible for performance decrement during repeated, long term exposure to vibration has been developed. The SPP is comprised of a trained Rhesus monkey, chronically implanted with probes to measure cardiovascular, hormonal and thermal parameters, with provisions for external measurements of the ECG, skin temperature, oxygen consumption, biomechanical parameters and performance level. Implementation of the SPP concept verifies the applicability and utility of the SPP and demonstrates the high quality, quantitative physiological and biomechanical data can be obtained with multiple systems from a performing subject during vibration exposure. Performance level, cardiovascular parameters, and biomechanical response of the SPP are presented as a function of vibration frequency and acceleration amplitude. (Author) See also AD-759 265.
