From: Mechanical vibration does not systematically reduce the tremor in essential tremor patients
Experimental setup, task and protocol design. (a) Placement of the piezoelectric actuators used to apply vibratory stimuli (fingertips, hand and forearms; palmar view). (b) Placement of the IMUs used to record the ongoing tremor (dorsal view). (c) Apparatus used to perform the postural task: patients rested the distal part of their arms on a horizontal elastic band in the arm support. (d) Schematic of the experimental protocol. In the top row, each rectangle is one of the five stimulation strategies; the expanded panel shows how each trial was divided in four 60-s epochs.
