C)Computed tomography
D)The electromyograph

Question

Quizplus · Accepted Answer

The electromyograph (EMG) is a device used to measure muscle tension and can be used to help people become more aware of tension in their muscles, including those in the forehead and fingers, which can contribute to muscle-tension headaches. By learning to lower tension through techniques such as relaxation exercises, individuals can decrease the discomfort and incidence of these headaches. Positron emission tomography, the electroencephalogram, and computed tomography are not relevant to this particular issue.
