WebMuscle stretch reflexes demonstrate rigid hypertonus, but there is no plastic rigidity, and repeated testing produces fluctuations in the tonus. Tremor is postural and high-frequency (8–10 Hz), but resting tremor of parkinsonian type is not observed. However, patients with adult onset may show resting tremor with lower frequency.
