Neurophysiology is a part of physiology. Neurophysiology is the study of nervous system function. It is possible that your back pain occurs because there is a problem some where different disciplines work together. Neurophysiology is also related or connected to other sciences like neurobiology, psychology, neurology, clinical neurophysiology, cognitive science, ethology, and neuroanatomy. So, the neurophysiology of back pain is examining if the pain is caused somewhere within your nervous system

Chronic Low Back Pain Study

Neurophysiologists studying chronic low back pain at Wayne State University are researching the role of the lumbar disc’s nucleus pulposus on the sensitization of nerves and the occurrence of chronic pain. Scientists have identified the facet capsules of the joints in the spine as the source of low back pain, so they are studying the neurophysiology of back pain to find ways to reduce or alleviate the pain.

The Neurophysiology Test Of Back Pain: Electromyogram

An electromyogram (EMG) tests for low back pain by monitoring the electrical muscle activity in the back. Muscle contraction is one of the causes of pain. Muscles contract because of electrical discharges of the nerves that control them. Nerve function can be impaired when the nerve is affected in muscle activity because of accident or injury, when the nerve may be compressed or diseased. This neurophysiology test of back pain measures all the variables in the nerve equation.

Doctors recommend EMGs for patients who have had pain for more than three or four weeks especially if nerve dysfunction is suspected. An EMG is recommended when patients have two or more diseases at the same time, like diabetic neuropathy coupled with a herniated disc with nerve root compression. An EMG can help the surgeon separate the damage attributable to diabetes from the damage attributable to the nerve root compression.

Spinal stenosis deforms bones until it compresses the spinal nervous system, it is another condition where neurophysiology of back pain manifests itself in an EMG. Sometimes surgery may be required in advanced cases, however, most surgeons will wait three months and redo the tests to be sure that surgery is necessary.

Some times using the EMG is the only way for a patient to prove that he is in pain. In litigation or workers compensation claims, where the patient is entitled to collect financial benefits that is sometimes necessary. However this is not recommended scientists studying the neurophysiology of back pain caution against an intrusive EMG unless it is absolutely necessary.
