Patient 6, Video Clip A. The video shows a jerky asymmetrical
postural tremor with dystonic posturing of the right upper limb, and jerky
dystonic head tremor.. Patient 6, Video Clip B. Slow pseudo-orthostatic tremor is
evident on standing.. Patient 7, Video Clip A. At rest this patient displays mild right
sided rest tremor of upper and lower limbs. There is a jerky mixed head tremor. On
posture holding she shows jerky right more than left upper limb tremor with
dystonic right upper limb posturing and position specificity.. Patient 7, Video Clip B. Gait is normal with no evidence of
tremor until she stands still, at which point slow pseudo-orthostatic tremor is
again seen.. Patient 8, Video Clip A. At rest the patient has right
torticollis with a jerky head tremor. There is action tremor of the upper limbs
with no bradykinesia.. Patient 8, Video Clip B. On standing a slow pseudo-orthostatic
tremor is evident, which improves with walking.

Frequency domain analysis (Figure 1C,D) confirmed that the dominant frequency was ~6 Hz for patient 7 and ~7 Hz for patient 8. Coherence analysis showed significant unilateral coherence around the dominant tremor frequency, with additional smaller peaks in the 12-20 Hz range (Figure 1E,F).
