Electromyography (EMG) and nerve conduction studies (NCS) are useful for assessing the function of:A. Peripheral nerves
Electromyography and nerve conduction studies (EMG/ NCS) are useful for assessing the function of peripheral nerves. EMG records muscle activity in response to a proximal stimulation of the motor nerve. NCS record the velocity and amplitude of the nerve action potential. EMG/NCS typically is performed approximately 3 to 4 weeks after an acute injury, as nerves distal to the injury continue to transmit electrical impulses normally until degeneration of the distal nerve progresses.
