Results: All 75 patients in this study showed normal EMG of the affected extremities and normal peripheral nerve conduction study. Because a herniated disc causes pressure on the nerve root, the nerve cannot supply feeling and movement to the muscle in a normal manner. Diskectomy is the surgical removal of the damaged portion of a herniated disk in your spine. PSW does not always mean ALS. A very common method of testing for peripheral nerve damage are electromyelegrams (EMG) and nerve conduction velocity (NCV) tests, they are called electrodiagnostic tests as well. EMG is a minimally invasive, office-based diagnostic test that evaluates how well the electrical signals between nerves and muscles are working. Back to Top The physician will correlate the findings on the MRI scan with the patient’s signs and symptoms of back pain in order to arrive at a clinical diagnosis.

For many minimally invasive spine procedures, you can be back to your normal activities as quickly as 3-4 weeks after your procedure. Cervical radiculopathy is often caused by “wear and tear” changes that occur in the spine as we age, such as arthritis.

For this test, the patient lies down flat on the back and the doctor gently raises the affected leg until pain is felt.

An EMG measures the electrical impulses transmitted along nerves, nerve roots, and muscle tissue. This test helps doctors to determine if pain or weakness originates in the muscles or nerves. If pain originates in the nerves, it may indicate that a herniated disc is compressing a nerve or part of the spinal cord. If symptoms of nerve root involvement are present for over six weeks an Electromyogram (EMG) and Nerve conduction study (NCS) can be performed.
