Quizplus · Accepted Answer

An electromyograph is an instrument used to measure muscle tension or activity. It is commonly used in sleep labs to monitor muscle movements during sleep, such as in cases of sleep disorders like sleep apnea or restless leg syndrome. Circadiometer measures the circadian rhythm, electroencephalograph measures brain waves, and polygraph measures various physiological responses like heart rate and breathing, but not specifically muscle tension.
