4. Purpose EMG is a diagnostic tool used in medical and clinical settings to evaluate the health and function of muscles and the nervous system . It provides valuable information about muscle activity , nerve conduction and neuromuscular disorders.

5. Principles Muscles generate electrical signals known as action potentials when they contract. EMG electrodes are placed on the surface of the skin (surface EMG) or inserted into the muscle (intramuscular EMG) The weak electrical signals from the muscles are amplified using specialized EMG equipment. EMG signals are typically processed to extract relevant information

6. 5. Examining the characteristics of MUPs , such as amplitude, duration, and shape. 6. EMG results are interpreted by a trained healthcare professional , typically a neurologist or physiatrist .

7. Application Clinically, electromyography is being used as diagnostic tool for: 1) neurological disorders neuromuscular diseases low back pain, and disorders of motor control. 2)EMG is routinely employed as an evaluation tool in applied research , physiotherapy , rehabilitation , sports medicine and training , and biofeedback

15. voltage ranges The voltage ranges for (EMG) signals in the human body: Resting State : from approximately 0.1 to 10 microvolts. Voluntary Contraction : from a few microvolts to several millivolts, roughly 10 microvolts to 5 millivolts Maximum Voluntary Contraction : from a few millivolts to tens of millivolts, approximately 5 millivolts to 50 millivolts.
