  • IN 1926, Roussy and Lévy 1 described a familial syndrome characterized by (1) clumsy gait, (2) abnormalities of equilibrium which were evident on standing and more pronounced with eye closure, (3) areflexia, (4) clubfeet, (5) awkwardness and weakness[jamanetwork.com]

Abnormal Gait
  • Foot drop causes frequent tripping, and with increasing weakness and attempts at compensation, the affected person develops an abnormal gait.[mda.org]
  • Also seen with Charcot-Marie-Tooth Disease is a condition known as " drop foot ", where the foot cannot be raised at the ankle, (see picture to the right) Ankle sprains, abnormal gait, diminished sensation, reflexes, and muscle strength are frequently[footdoc.ca]

  • Treatment with clonazepam and gabapentin did not yield any benefits. Treatment with intravenous cyclophosphamide at a dose of 1 g/m 2 was repeated four times at 3-month intervals because of recurrent urinary infections.[movementdisorders.org]


  • (Outcomes/Resolutions) The prognosis for Roussy-Lévy Syndrome depends on the severity of the signs and symptoms of the disorder Individuals with mild forms of Roussy-Lévy Syndrome have a better prognosis than those with severe forms of the disorder However[dovemed.com]
