Emg came back normal, results stated no neuropathy (left leg below knee). Does that leave me with a mild case of crps? See pictures in health file.

Emg came back normal, results stated no neuropathy (left leg below knee). Does that leave me with a mild case of crps? See pictures in health file.

Maybe: I certainly would not hang my hat on EMG results - they can be affected by many factors. Neuropathy can take awhile to show pos. On emg. There certainly is a chance it is crps. Hope this helps. ...Read more

Electromyography (Definition)

Emg (electromyography) is a test of your muscles and nerves. It is typically performed along with nerve conduction studies (ncs). The EMG portion involves placing a recording pin (like a fine wire antenna) into various muscles, looking for 'muscle distress signals' that could suggest nerve or muscle diseases/problems. Nerve conduction studies involve stimulating nerves ...Read more

How is emg done?

How is emg done?

Carefully: Emg or electromyography is a test done that requires a trained physician (pmr or neuro md) to insert a thin needle electrode into specific muscles to determine whether there is muscle, motor nerve, (or nm junction with special techniques) injury. It can be uncomfortable at times and is usually combined with a ncs (nerve conduction study) test to physiologically examine peripheral nerve and muscle. ...Read more

Does a emg test hurt?

Does a emg test hurt?

A little bit: The level of pain varies from patient to patient and with the doctor who is performing the test. Most patients find the discomfort relatively mild and no big deal. ...Read more

Is an emg test painful?

Uncomfortable: Like a lot of medical tests emgs are not fun. I tell patients there will be some discomfort but it should be tolerable and not last too long. ...Read more

Does emg always show injury?

Does emg always show injury?

no: It has great specificity (when it shows a problem there's really a problem), but poor sensitivity (when the EMG does not show a problem there in fact may be a problem). So EMG does not always show injury. ...Read more

What is electromyography (emg )?

Electromyography: Emg and ncv testing is used to help diagnose nerve and muscle problems. Examples include spinal nerve impingement (from herniated disc), carpel tunnel syndrome, ulnar syndrome, sources of radiating pain. Pain, numbness, weakness, muscle fatigue are some of the reasons that you may need an emg/ncv test. ...Read more

What is an emg nerve test used for?

What is an emg nerve test used for?

Nerves & muscles: Emg and nerve conduction studies are used to detect abnormalities of nerves and muscles. The test evaluates nerve roots as they exit your spine, the nerve plexus, peripheral nerves, the nerve-muscle junction, and muscle itself. It can detect pinched/compressed nerves (sciatica, carpal tunnel, and others), muscle disorders, neuropathy, and many other neuromuscular conditions. ...Read more

Emg/ncv test will show what exactly?

See below: Ncv, or nerve conduction velocity, is an electrical diagnostic test that provides information about abnormal conditions in the nerves. Emg, or electromyography is a technique for evaluating and recording the electrical activity produced by muscles. ...Read more
