Video 1.

Spiral drawing. The Parkinson’s disease patient’s re-emergent tremor emerges during spiral drawing (2 seconds into the video). As the patient draws spirals, his distal upper limb (i.e., hand) is in a stable position, and a re-emergent tremor arises, mainly involving the thumb and phalangeal joints. The patient, enrolled in a clinical research study at Yale University, signed informed consent, including consent to be videotaped and for publication of the videotape.
