ANS)

Clinical Principle of EMG(Electromyography)

The EMG compute the muscle reaction or the electrical action in regards to a nerve's stimulation of muscle.This test is done to identify the neuromuscular deformities.At the time of testing,one or more than one small sized needles(commonly known as electrodes) are placed through the skin to the muscle.

Physiological principle of EMG

Actually electromyography signal is a kind of biomedical signal which calculate the electrical current produced in the muscle at the time of its contraction showing the neuromuscular activity and because of that the electromyography signal is a very complex signal ,that is maintained by the nervous system and which is conditional on anatomical and physiological features of the muscles.

Lifting the four loads in ascending order produces larger EMG signals as the loads get heavier. 1. Discuss how you think the EMG signals for each load might change if the loads were lifted in descending order, or in random order. 2. Explain your answer with reference to the underlying physiological mechanisms associated with muscle strength, motor unit activity, and muscle fatigue.
