PY - 2012 T2 - Movement Disorders, 3e AB - The term “movement disorders” has been coined for diseases characterized by abnormal or excessive movements occurring in conscious patients. “Extrapyramidal disorder” is an older classification of central motor disturbances not involving the corticospinal pathway. Involuntary movement can occur in a setting where there is also difficulty in initiating or executing voluntary movement. The commonest example of combined hyperkinetic and hypokinetic features is Parkinsonism, where tremor is frequently associated with bradykinesia and rigidity.
