title: Stretch reflexes and parkinsonian tremor.
abstract: By coupling human limbs to a machine, which drives a single joint through sinusoidal flexion-extension movements, it is often possible to entrain the resting tremor of Parkinson's disease. Entrainment is most likely to occur when the imposed movement is large in amplitude and close in frequency to the spontaneous tremor.
