Methods for performing physiological stress tests
First Claim
1. A method for assessing the physiological effect of physiological and psychological stressors on a subject, the method comprising:
- presenting the subject with a first physiological stressor;
receiving surface electromyography (sEMG) data points describing muscular activity of the subject while the subject is experiencing the physiological stressor;
presenting the subject with a first psychological stressor;
receiving sEMG data points describing muscular activity of the subject while the subject is experiencing the psychological stressor;
calculating a first index value summarizing at least a portion of the sEMG data points received while the subject is presented with the psychological stressor; and
calculating a second index value summarizing at least a portion of the sEMG data points received while the subject is presented with the physiological stressor, wherein the act of analyzing the sEMG data points includes analyzing the first and second index values.

Abstract
Systems and methods are provided for evaluating the risk of stress-related injury associated with a predetermined activity. One embodiment involves collecting physiological data while a subject performs a predetermined task, collecting psychological data while the subject performs a cognitive task, and ascertaining the risk of stress-related injury based on both the collected physiological data and the collected psychological data. Another embodiment involves presenting a subject with a plurality of mental and physical tasks during which physiological data, psychological data, and/or both is collected, and determining the risk of stress-related injury based on the data collected. Yet another embodiment includes a test circuit for measuring stress responses that includes both physiological test stations and psychological test stations. Physiological stress is evaluated in the form of surface electromyography data that is quantified into a single index value, as will be described in detail herein.
