Figure 1. Finger trajectories are displayed in Figure 2, and the quantitative amplitude and frequency are displayed in Figure 3.
Hand movement trajectories. Index finger movement trajectories in the finger-to-finger task illustrate the tremor amplitudes and frequencies of the hands, with deep brain stimulation (DBS) Off and On. Normal, normal healthy person; L, left hand; R, right hand; Off, DBS Off; On, DBS On.

Power spectrum of the hand trajectories. The power spectrum of the hand trajectories reveals the amplitudes and dominant frequencies of the tremors at the beginning and end of the movements approaching the target, with DBS Off and On. L, left hand; R, right hand; Off, DBS Off; On, DBS On; a.u., arbitrary units.
