AB Movements  disorders  are  neurologic  syndromes  that  involve  impaired  performance  of  voluntary  movements,  dysfunction  of  posture,  the  presence  of  abnormal  involuntary  movements,  or  the  performance  of  normal-appearing  movements  at  inappropriate  or  unintended  times.1,2  These  movement  abnormalities  are  not  due  to  weakness  or  spasticity.  Movement  disorders  are  traditionally  divided  into  hyperkinetic  disorders  and  hypokinetic  disorders.  Hyperkinetic  movement  disorders  are  characterized  by  an  excess  of  movement,  whereas  hypokinetic  movement  disorders  are  characterized  by  a  paucity  of  movement.  In  childhood,  hyperkinetic  movement  disorders  are  far  more  common  than  hypokinetic  movement  disorders.  Hyperkinetic  movement  disorders  include  tics,  stereotypies,  chorea,  athetosis,  ballism,  dystonia,  myoclonus,  and  tremor.  The  primary  hypokinetic  movement  disorder  is  parkinsonism,  which  is  characterized  by  bradykinesia,  tremor,  rigidity,  and  postural  instability.  Parkinson's  disease,  which  is  the  most  common  hypokinetic  movement  disorder  in  adults,  is  exceedingly  rare  in  children.
