Fig. 2From: Inhibition of Parkinsonian tremor with cutaneous afferent evoked by transcutaneous electrical nerve stimulationResults of one trial with low intensity stimulation amplitude of one subject (PD4). The amplitude of current stimulation was set at radiating threshold (RT). Column a shows the 6 preamplified EMGs during the trial. The seventh row shows the electrical stimulation. The time duration of one trial includes 5Â s prior to stimulation, 5Â s during stimulation and 5Â s after stimulation. Column b shows 7 degrees of freedom (DOFs) in joints. During stimulation period, neither EMGs nor DOFs show an apparent reduction when electrical stimulation at RTBack to article page
