Parkinson disease (PD) is a multisystemic neurodegenerative disease that causes progressive deterioration of motor, autonomic, and neuropsychiatric functions. The cardinal motor features of Parkinsonism include bradykinesia, rigidity, rest tremor, and postural instability. Patients commonly also have masked facial features, flexed posture, hypophonic speech, and slowed eye movements. Rest tremor and dyskinesia are particularly enhanced during difficult, distracting cognitive or motor tasks; therefore, it is important to include these in any protocol. Special precautions must be taken so that the patient does not fall. Other special considerations for videotaping PD patients are related to the stage of the disease and the predominant symptoms.
