definition: Low back pain affects a significant portion of the population, with epidemiologic studies reporting a lifetime prevalence of 49% to 70%. Sciatica, also referred to as lumbosacral radicular syndrome, is a type of low back pain that is characterized by pronounced posterior radiating leg pain. The pain follows a distribution served by a lumbar or sacral spinal nerve root and is often accompanied by sensory, motor, or tendon reflex abnormalities.
