What is EMG / ENMG (Electroneuromyography)?
EMG; It means printing the electrical signals received from nerves and muscles.
EMG; It is an examination method used to diagnose diseases affecting the nerves, to confirm the diagnosis, to determine the severity of functional disorders or structural damage, to monitor the disease process and to evaluate the effect of the applied treatment.
Nerve Conduction Studies
During EMG examination; The signals in these nerves are revealed by electrical stimulation given to certain points of the nerves with stimulating electrodes attached to the skin. This signal is recorded with recording electrodes placed on the skin.
Needle EMG
This process; It is performed to insert special recording electrodes called needle electrodes into the muscle tissue and record electrical signals on the muscle fibers.
The signals produced by muscle fibers during mild and strong contractions are evaluated. Thus, information is obtained regarding where the detected disease is in the body or, in the case of a widespread disease, the extent of the disease.
EMG Usage Areas:
Polyneuropathies: Cause widespread damage to peripheral nerves, such as diabetes, B12 deficiency or kidney failure.
Focal neuropathies: Diseases that usually cause damage to a single nerve, especially trap neuropathies (e.g. Carpal, Cubital, Tarsal Tunnel Syndoms).
Radiculopathies: Diseases that arise from the spinal cord, such as a lumbar or cervical disc herniation. Diseases that cause damage to nerve roots.
Myopathies (Muscle diseases): Diseases that cause damage to muscle fibers.
Motor Neuron Diseases: Diseases that cause damage to motor nerve cells in the spinal cord, such as polio or ALS. diseases.
Neuromuscular Diseases: Diseases that disrupt nerve-muscle transmission, such as Myasthenia Gravis.
