Stations for performing physiological stress tests

A method for determining the risk of stress-related injury associated with a predetermined activity, the method comprising:

• presenting a subject with a test circuit, the test circuit including a plurality of test stations, wherein each test station includes one or more physiological and/or psychological stressors;
• collecting surface electromyography (sEMG) data points describing muscular activity of the subject while the subject is at a first test station experiencing a first physiological stressor;
• calculating a first index value summarizing the sEMG data points collected while the subject is experiencing the first physiological stressor at the first test station;
• collecting sEMG data points describing muscular activity of the subject while the subject is at a second test station experiencing a first psychological stressor;
• calculating a second index value summarizing the sEMG data points collected while the subject is experiencing the first psychological stressor at the second test station;
• and
• determining the risk of stress-related injury associated with the predetermined activity based on the first and second index values.

A test circuit for accessing the physiological effect of mental and physical stressors on a subject comprising:

• a first test station including:
• a first plurality of surface electromyography (sEMG) sensors for collecting first sEMG data describing muscular activity of the subject while the subject is experiencing a physiological stressor;
• and
• a first processing circuit communicably coupled to the first plurality of sEMG sensors for calculating a first index value based on the first sEMG data;
• and
• a second test station including:
• a second plurality of sEMG sensors for collecting sEMG data describing muscular activity of the subject while the subject is experiencing a psychological stressor;
• and
• a second processing circuit communicably coupled to the second plurality of sEMG sensors for calculating a second index value based on the second sEMG data.
