Periodic Limb Movement Disorder. Periodic limb movement disorder involves a rhythmic jerking of the legs and sometimes arms, which may result in poor quality sleep and daytime fatigue. Unlike restless leg syndrome, these movements are involuntary and usually take place when a person is asleep.
Systemic Features. Symptoms consisting of a spastic gait and distal sensory impairment usually appear in the first decade and are slowly progressive. Increased deep tendon reflexes and extensor plantar responses may be present at that time but later distal leg muscle atrophy and pes cavus appear. The ankle reflexes later disappear. Cognitive function is normal and adults are able to lead an independent life.
