Radiculopathy refers to a condition in which one or more nerves are affected and do not work properly (ie. neuropathy). The location of the injury is at the level of the nerve root (level where the nerve exits the spinal
cord and surrounding bones). This can result in radicular pain, weakness, numbness, and/or difficulty controlling specific muscles.
In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord. However, the pain or other symptoms often radiate to the part of the body served by that nerve. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm. Likewise, an impingement in the lower back or sacral spine can be manifested with symptoms in the leg and foot.
They’re a significant number of variables that cause radiculopathy so a thorough history and examination is needed to rule-out and implicate the cause for the reported pain and dysfunction.
