^¥Bradykinesia restricted to lower extremities of mild-moderate severity

^βBradykinesia mild-moderate in upper extremities and mild in lower extremities

^ΩBradykinesia mild-moderate in upper extremities, absent-mild in lower extremities and mild rigidity in upper extremities

^фBradykinesia mild in upper extremities only

Parkinsonism is determined by the presence of bradykinesia plus one of the other clinical features (rigidity, postural instability, and resting tremor).
