Radiculopathies
Overview Radiculopathy refers to symptoms or impairments related to the involvement of a spinal nerve root. The spinal nerve roots serve as the main communication between the central nervous system (i.e. the spinal cord) and the peripheral nerves. When a spinal nerve root is affected, it is known as radiculopathy. Radiculopathies may be single or multiple. When multiple nerve roots are affected it is known as polyradiculopathy. The symptoms of radiculopathy are usually characteristic because each root supplies a specific area of cutaneous tissue, known as the dermatome, and a functional group of muscles, known as a myotome. Therefore, patients typically
