Acute lumbosacral radiculopathy is a diffuse disease process that affects more than 1 underlying nerve root, causing pain, loss of sensation, and motor function depending on the severity of nerve compression. Lumbosacral radiculopathy is very common.[1] Most cases of lumbosacral radiculopathy are self-limited. The most common symptom in radiculopathy is . The straight leg raise test also called the Lasegue test, is a fundamental neurological maneuver during the physical examination of a patient with lower back pain that seeks to assess the sciatic compromise due to lumbosacral nerve root irritation.
