EMG can also be used for indicating the amount of fatigue in a muscle. The following changes in the EMG signal can signify muscle fatigue: an increase in the mean absolute value of the signal, increase in the amplitude and duration of the muscle action potential and an overall shift to lower frequencies. Monitoring the changes of different ...
Electromyography is the measurement and analysis of the electrical activity in skeletal muscles. This technique is useful for diagnosing the health of the muscle tissue and the nerves that control them. [8] EMG measures action potentials, called Motor Unit Action Potentials (MUAPs), created during muscle contraction.
In general, fatigue protocols have shown increases in EMG data over the course of a fatiguing protocol, but reduced recruitment of muscle fibers in tests of power in fatigued individuals. In most studies, this increase in recruitment during exercise correlated with a decrease in performance (as would be expected in a fatiguing individual).
The results show the appearance of action potential or graded potential spikes. While interpretation of the results requires background knowledge, irregular data can be used to diagnose many diseases. If the activity of the nerves at rest is abnormal, this may indicate nerve lesion, radiculopathy, or lower motor nerve degeneration. The ...

The interpretation of nerve conduction studies is complex and requires the expertise of health care practitioners such as clinical neurophysiologists, medical neurologists, physical therapists, or physiatrists. [6] [7] [8] NCS results provide information on whether a nerve conducts electrical signals at a normal speed and strength ...
