Paraparetic Guillain-Barré syndrome: Nondemyelinating reversible conduction failure restricted to the lower limbs.

Introduction: Paraparetic Guillain-Barré syndrome (GBS) is a rare subtype of GBS characterized by leg weakness and areflexia in the absence of neurological involvement of the arms, cranial nerves, or respiratory muscles. Onset is characterized by lower back, buttock, or leg pain, followed by development of symmetric flaccid limb weakness in the absence of sensory disturbance.

Methods: We describe an elderly woman who developed postinfectious symmetric flaccid leg weakness in the absence of sensory disturbance.
