Wavelet and multifractal analysis has shown that alterations in oscillatory activity accompanied by long-term correlations between successive values of these oscillations occur as a result of movement disorders in the structure of patterns of involuntary oscillatory hand movements that arise during motor task performance. These alterations cause a significant increase in the variation of the amplitude of involuntary oscillatory hand movements in an individual with Parkinson’s disease compared to healthy individuals. The mechanism of the appearance of correlated dynamics is associated with an increase in the contribution of strong fluctuations of successive values of involuntary oscillations. A decrease in the variation of the amplitude of these oscillations and the energy of their wavelet spectrum in association with antiparkinsonian drugs is accompanied by a decrease in long-term correlations; multifractal characteristics tend to be attributed to the range that is characteristic of healthy individuals.

小波和多重分形分析表明，伴随这些振荡的连续值之间的长期相关性而发生的振荡活动的改变，是由于运动任务执行期间出现的不自主振荡手部运动模式结构中的运动障碍而发生的。与健康个体相比，这些改变导致帕金森病患者不自主摆动手部运动幅度的变化显着增加。相关动力学出现的机制与无意识振荡的连续值的强烈波动的贡献增加有关。与抗帕金森病药物相关的这些振荡幅度的变化及其小波谱能量的降低伴随着长期相关性的降低；多重分形特征倾向于归因于健康个体特征的范围。
