WebPolysomnography is for studying sleep and its effect on various organ functions. Sleep stages are constructed by monitoring electroencephalogram, chin electromyogram, and eye movements by electrooculogram. Sleep architecture is comprised of the wakefulness stage, Stage W, and NREM and REM sleep stages. Continuous monitoring of respiratory ... Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. Motor neurons transmit electrical signals that cause … See more Your doctor may order an EMG if you have signs or symptoms that may indicate a nerve or muscle disorder. Such symptoms may include: 1.
