Electrodiagnostic Evaluations/EMGs

Electrodiagnostic Evaluation, also called Electromyography or EMG, is a test that can help a doctor identify the cause of pain, numbness, tingling, weakness, paralysis, spasms, or other symptoms that you may report in your arms or leg. EMGs are offered at multiple Spaulding Rehabilitation Network locations.

Using weak electric impulses and thin needles, EMG measures how well specific nerves and muscles are working. EMG has been used widely since the mid-1980s to help diagnose a range of diseases and conditions, including carpal tunnel syndrome, neuropathy, ALS, myopathy, and radiculopathy, commonly known as a herniated disc.
