ELECTROMYOGRAPHY (EMG) & ELECTRODIAGNOSIS
Electromyography, otherwise known as EMG, discussed the study of electrical impulses as they are transmitted from the central nervous system to the extremities. Nerve conduction velocities (NCV Studies) also measure the function of nerves as they passed along the extremities. EMG and NCV studies are performed to determine the causes of painful syndromes of the neck, back, and the extremities. The studies are helpful and explaining the pain syndromes and directing treatment. These studies can be helpful in defining such conditions as radiculopathy (compressed or irritated nerve to an extremity), and nerve compressions of the arm or leg, or neuropathies due to medical conditions.
