EMG/NCS (Nerve Conduction Study)

NCS and EMG tests are electrodiagnostic procedures that measure the electrical activity of muscles and
nerves. NCS uses electrode stickers applied to the skin to measure the speed and strength of electrical
signals between two points. During an EMG, a small needle electrode about the size of an acupuncture
needle is inserted into the muscle and records the electrical activity of that muscle. Together, these tests
can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission to
help in the diagnosis of neuromuscular disease.
