Examination may be normal or may show muscle weakness that progressively worsens as the muscle is used. In many patients the eye muscles are affected first. Reflexes and sensation are normal. Weakness may affect the arms, legs, breathing or swallo...

Myasthenia gravis (MG) is an autoimmune disease that causes muscle weakness. It affects the neuromuscular junction, interrupting the communication between nerve and muscle, and thereby causing weakness. People with MG may have difficulty moving th...

Myasthenia gravis is often diagnosed accurately by a careful medical history and a neuromuscular exam, but several tests are used to confirm the diagnosis. Other conditions causing worsening of bulbar and skeletal muscles must be considered, inclu...

A delay in diagnosis of one or two years is not unusual in cases of MG. Because weakness is a common symptom of many other disorders, the diagnosis is often missed in people who experience mild weakness or in those individuals whose weakness is re...

Electromyography is a test that assesses the health of the muscles and the nerves controlling the muscles.
|
|
Electromyography (EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease. Purpose Muscles are stimulated by signals from nerve cells called motor neurons.
|
 |
Electromyography (EMG) is used to detect, process, and record electrical muscle activity in order to aid in the diagnosis of neuromuscular disease. Purpose EMG is performed most often to help diagnose different neuromuscular diseases causing weakness.
|
 |
Electromyography (EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease, which affects muscle and peripheral nerves. Purpose Muscles are stimulated by signals from nerve cells called motor neurons.
|
|
A nerve conduction study is a test that measures the movement of an impulse through a nerve after the deliberate stimulation of the nerve. Purpose The ability of a nerve to swiftly and properly transmit an impulse down its length, and to pass on the impulse to the adjacent nerve or to a connection muscle in which it is embedded, is vital to the performance of many activities in the body.

 |
EMG and NCS TestsElectromyography(EMG)and nerve conduction studies(NCS)are tests that measure muscle and nerve function. In most cases, both tests are performed.

 |
In the Tensilon test, the drug Tensilon is administered, and muscle response is evaluated to help diagnose myasthenia gravis (a chronic, progressive disease characterized by weakness of the voluntary muscles).
|
|
Tensilon is the trade name for edrophonium chloride. The Tensilon test is an injection of edrophonium chloride used to diagnosis myasthenia gravis (MG).
