Neuromuscular (EMG) Laboratory
Muscle pain, weakness or numbness may be symptoms of a neuromuscular disorder. At the Neuromuscular Laboratory at Rhode Island Hospital, physicians use specialized tests called nerve conduction studies and electromyogram, also known as EMG, to perform functional examinations on muscles and nerves.
Nerve conduction studies use a small amount of electrical stimulation to assess the function of nerves. An EMG evaluates how well the muscle and nerves are communicating by recording electrical signals between the two. Abnormal function of nerves, muscles or communication between the two can signal a neuromuscular disease.
The Neuromuscular Laboratory features three state-of-the-art electromyography machines that can perform a wide variety of tests. The tests are supervised by physicians board certified in neurology and clinical neurophysiology. Comprehensive reports are sent to the referring physician within approximately one week.
Your doctor may order an EMG if you have signs or symptoms that may indicate a nerve or muscle disorder.
Such symptoms may include:
- Muscle weakness
- Muscle pain or cramping
- Certain types of limb pain
Nerve conduction studies and EMG can be used to evaluate for:
- Carpal tunnel syndrome
- Peripheral neuropathies
- Neuromuscular junction disorders
- Muscle disorders
For more complicated neuromuscular conditions we also offer:
- Single fiber electromyograms
- Repetitive nerve stimulations
