Diagnostic tests for Leg numbness:

Various tests are used in the diagnosis of Leg numbness. Some of these are listed below :

  • Physical examination
    • Feel the pulses in the legs - if reduced or absent should suggest peripheral atherosclerosis (hardening of the arteries) or obstruction of the abdominal aorta and its branches by atherosclerosis.
    • Examine for a positive straight leg raising test (straightening the leg at the knee while lying on a bed causing pain in thigh, buttock and back) and/or a reduced ankle reflex- indicates herniated disk of L4-5 or L5-S1, lumbar spondylosis, spinal stenosis, cauda equina tumor or spondylolisthesis
    • Examine for a positive femoral stretch test (with the person laying on their stomach, flex knee with hip lifted in extension causes pain in the front of the thigh and the back) or a decreased knee jerk - indicates a herniated disk of L3-4 or L2-3 or lumbar spondylosis.
    • Examine the peripheral reflexes. If diffusely overactive may suggest multiple sclerosis, pernicious anemia, spinal cord tumor, syringomyelia (presence of cavities within the spinal cord) or anterior spinal artery occlusion. If diffusely under active may suggest peripheral neuropathy, poliomyelitis, Guillain-Barre syndrome, cauda equina tumor, metastatic tumor of the lumbar spine and occasionally pernicious anemia or peroneal neuropathy (disease of the peroneal nerve)
