The purpose of these studies is to determine whether nerve damage is present and how severe that damage may be. (wikipedia.org)

Bilateral sciatic nerve pain is when pain occurs in both legs at the same time. (shifarejuvenation.com)

As far as the pathophysiology of this condition is considered, some abnormality in the function of our immunity system would act in a way that damages the myelin sheath - the protective layer covering nerves. (pediaa.com)
Altered nerve function brought on by a condition, like diabetes. (wellnessdoctorrx.com)
Before induction of anesthesia, a train-of-four (TOF) electromyography was installed in order to monitor neuromuscular function during operation. (asahq.org)

Shoulder pain is discomfort involving the musculoskeletal tissues, nerves, or blood vessels in your shoulder area. (arizonapain.com)
A pinched nerve occurs when too much pressure (compression) is applied to a nerve by surrounding tissues. (telehealthpharmacy.ie)

The time an impulse takes to traverse a measured length of nerve determines conduction velocity. (merckmanuals.com)

Nerve conduction studies help diagnose nerve damage or disease. (medlineplus.gov)
Doctors can diagnose your radiculopathy with magnetic Resonance Imaging ( MRI ) showing the disc out of place and pushing in a nerve root. (pregistry.com)

One of these structures is the posterior tibial nerve, which is the focus of tarsal tunnel syndrome. (bakersfieldfootandanklesurgeons.com)

Individuals feeling tingling or pins and needles sensations that overtake the arms or legs could be experiencing paresthesia, which occurs when a nerve has been compressed or damaged. (wellnessdoctorrx.com)
A person with flat feet is at risk for developing tarsal tunnel syndrome, because the outward tilting of the heel that occurs with "fallen" arches can produce strain and compression on the nerve. (bakersfieldfootandanklesurgeons.com)
