Which of the following is NOT a typical motor symptom of Parkinson's disease?

Explanation:
Parkinson's disease produces hypokinetic motor features from loss of dopamine in the substantia nigra, which disrupts basal ganglia circuits that regulate movement. The classic motor signs are resting tremor, bradykinesia, rigidity, and a shuffling gait with reduced arm swing. Hyperreflexia, on the other hand, is not part of this pattern; reflexes are typically normal in Parkinson's and hyperreflexia points to upper motor neuron problems or other conditions. So the feature described as heightened reflexes does not fit the motor symptom profile of Parkinson's disease.
