Motor disorders are characterized by impaired voluntary movement, the presence of involuntary movements, or both. There may be impaired targeting and velocity of intended movements, abnormal involuntary movements, abnormal postures, or excessive movements that appear normal at inappropriate or unintended times. Movement disorders in children include athetosis, chorea, dystonia, myoclonus, parkinsonism, stereotypies, tics, and tremor (Carducci and Fernandez-Alvarez, 2007; Singer et al., 2016). Movement disorders may be accompanied by weakness, spasticity, hypotonia, ataxia, apraxia, and other motor deficits, although many authors do not include these accompanying deficits.
