Electromyography (EMG) is a diagnostic investigation carried out to evaluate the health and functioning of muscles and the nerves that regulate their activities. EMG can be used to diagnose disorders such as muscle dysfunction, nerve dysfunction, or problems with signal transmission between the nerves.
The nerves that innervate the muscles are called motor neurons. They transmit electrical signals that direct the muscles to contract. Small metal discs called electrodes are used to translate these electrical signals into sounds, graphs, or numerical values that are then interpreted into a report by a specialist.
During the test, one or more needle electrodes are introduced through the skin into the muscle to record its electrical activity. Another part of the EMG is called the nerve conduction study. During this procedure, surface electrodes are applied to the skin to measure the strength or speed of the signals travelling between the different muscles.
You might be asked to get an EMG done if you are exhibiting signs and symptoms of a nerve or muscle disorder. Such symptoms include numbness, tingling, muscle pain, cramps or weaknesses, and limb pain.
The results of an EMG help to diagnose or rule out several medical conditions, including muscular dystrophy, polymyositis, myasthenia gravis, carpal tunnel syndrome, peripheral neuropathy, and amyotrophic lateral sclerosis, herniated disc, and poliomyelitis.
The Department of Neurosciences at Kokilaben Dhirubhai Ambani Hospital, Navi Mumbai houses one of the best EMG Test Centres in Navi Mumbai. In addition to other advanced medical machines, the department is equipped with state-of-the-art EMG machines. There is a fully equipped Cath Lab where experienced neurological professionals carry out various neuro interventions.
