Which physiological measure is frequently used to measure muscle tension?
A) GSR (galvanic skin response)
B) EMG (electromyogram)
C) EEG (electroencephalogram)
D) fMRI (functional MRI)

Question

Quizplus · Accepted Answer

EMG (electromyogram) is the most commonly used physiological measure to measure muscle tension. It records the electrical activity produced by skeletal muscles when they contract, allowing researchers to measure muscle tension with a high degree of accuracy. GSR (galvanic skin response) measures the electrical conductance of the skin in response to sweat glands, and is typically used to measure emotional arousal or stress. EEG (electroencephalogram) measures brain activity, and fMRI (functional MRI) measures changes in blood flow in the brain, but neither of these measures are directly related to muscle tension.
