Nerve test - what is EMG? How is it done?

EMG is a measurement method that uses electricity and needles to diagnose nerve and muscle diseases. It usually consists of 2 steps; In the first stage, conduction studies are carried out electrically. It is investigated whether there is any disruption, deceleration or contraction in the nerve conduction. In the second stage, muscles are mainly evaluated. Special needles are immersed in suspected muscles and the obtained data is automatically transferred to the computer.

Nerve test - Why is EMG done?

Mostly for the diagnosis of nerve impingement. EMG is the only diagnostic method of carpal tunnel syndrome, especially in the first 3 fingers of the hand, which complies with the nights and pain. Nervous squeezing of the elbow with numbness and tingling on the fingertip of the hand is also diagnosed only by EMG. The nerve test is also used to investigate the cause of loss of power and loss of feelings in hands and feet.

EMG is also very useful in diagnosing nerve injuries due to hernia and neck hernias. The grade of the nerve damage due to the foot is determined and it is determined which muscles are most affected. EMG is a very, very helpful way to make a decision on the operation of the waist and neck hernia. In summary, the precise diagnosis of nerve damage due to the hernia is provided by EMG, it is more useful than the MR when the operation is decided, and it gives us an idea about which methods to use in physical therapy.

EMG is absolutely necessary for diagnosing neuropathy which causes complaints such as burning and numbness in hand and foot that develop in time in diabetes patients. This disease can cause wounds and ulcers especially if it is not treated early. Early detection and EMG monitoring should be done at certain intervals.
