Statistical results of the changes of tremor PSD prior to and after voluntary movement. (a) exhibits that the number of tremor inhibited trials was significantly larger than non-inhibited trials. (b) displays the reduction of tremor component that the tremor component in the hand prior to voluntary movement is greater than that after voluntary movements. In (c) and (d), the energy component of tremor is reduced in most joints and sEMG of muscles in most patients, except for a few joints and sEMG
