Final answer:
Electromyography (EMG) is a technique used to measure and analyze muscle activity. It involves artificially stimulating a muscle and detecting the muscle response. EMG is used in healthcare to assess muscle health, diagnose disorders, and monitor rehabilitation.
Step-by-step explanation:
In electromyography (EMG), a muscle is artificially suprastimulated to elicit a muscle response. EMG is a technique used to measure muscle activity and analyze the electrical signals generated by muscle contractions.
During an EMG procedure, electrodes are placed on the skin above the muscle being tested. When the muscle is stimulated, electrical impulses are generated, and the electrodes detect and record these impulses.
By analyzing the EMG signals, healthcare professionals can assess the health and function of muscles, diagnose neuromuscular disorders, and monitor the progress of rehabilitation therapies.
