Nerves are complex fibres in our body which carry impulses from the periphery to the central nervous system ( brain and spinal cord) and vice versa. (blogspot.com)

A herniated disc may also be the result of a formation of a bone spur that compresses the sciatic nerve causing sciatica. (drcianci.com)

Mean Nerve Conduction Velocity (MNCV)- How fast electrical signals move through a nerve. (dpsnutrition.net)
A nerve conduction velocity test is almost always performed during the same visit as an EMG. (medlineplus.gov)

describes a condition involving painful pressure on a specific nerve in the back. (rxlist.com)
Chiropractors use spinal manipulations to coax the herniated disc back into position and remove pressure from the sciatic nerve. (divinespine.net)
This awkward structural formation often places pressure on the sciatic nerve. (1on1ptasheville.com)
Sciatica may be triggered by anything that can place pressure on the sciatic nerve or compress the nerve may trigger sciatica. (ourfamilychiropractor.com.au)
Commonly, a misalignment of one or more of the lumbar vertebra causing pressure on the nerve is responsible. (captanischiropractic.com)
With most patients, a series of adjustments to move the related vertebra back to a more normal position is helpful to reduce the pressure on the nerve. (captanischiropractic.com)
