    • Proprioceptive and vibration loss below the level of the lesion
    • Spared pinprick sensation
  • Causes
    • Multiple sclerosis (cerebellar signs, INO, RAPD)
    • Tabes dorsalis (Argyll-Robertson pupils)
    • Sub-acute combined degeneration of the cord from B12 deficiency (absent ankle jerks, macroglossia)
