An exam of the nerves and muscles shows weakness, often beginning in one area. There may be muscle tremors, spasms, twitching, or loss of muscle tissue (atrophy).

The diagnosis of Lou Gehrig's disease begins with a complete medical history and physical exam, plus a neurological exam to determine the distribution and extent of weakness. An electrical test of muscle function, called an electromyogram, or EMG,...

Electromyography(EMG) is a test that checks the health of the muscles and the nerves that control the muscles.
|
|
Electromyography(EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease.Muscles are stimulated by signals from nerve cells called motor neurons. This stimulation causes electrical activity in the mus...

This test roughly measures the types of protein in the fluid (serum) part of a blood sample. See also:Immunoelectrophoresis - serumImmunofixation - serumSerum globulin electrophoresisLipoprotein electrophoresisA blood sample is needed.

Separation is based on differences in the charge(and sometimes size) of the molecules, which determines their rate of movement in an electric field. Serum protein electrophoresis is a screening test that measures the major blood proteins.
|
|
Serum protein electrophoresis(SPEP) is a screening test that measures the major blood proteins by separating them into five distinct fractions: albumin, alpha 1, alpha 2, beta, and gamma proteins. Protein electrophoresis can also be performed on u...

A nerve conduction study is a test that measures the movement of an impulse through a nerve after the deliberate stimulation of the nerve.The ability of a nerve to swiftly and properly transmit an impulse down its length, and to pass on the impuls...

Electromyography (EMG) and nerve conduction studies (NCS) are tests that measure muscle and nerve function. In most cases, both tests are performed. NCS is most often done first.
