Periodic Limb Movement Disorder (cont.)

Periodic Limb Movement Disorder Symptoms

Patient Comments

The most common symptoms noted by people with PLMD are not leg movements but poor sleep and daytime sleepiness. Many people with PLMD are unaware of their leg movements unless their bed partner tells them.

Leg movements involve one or both limbs.

  • Typically the knee, ankle, and big toe joints all bend as part of the movements.
  • The movements vary from slight to strenuous and wild kicking and thrashing.
  • The movements last about 2 seconds (and thus are much slower than the leg jerks of myoclonus).
  • The movements are rhythmic and repetitive and occur every 20-40 seconds.
