Paradoxical kinesia in Parkinson′s disease / 中华神经科杂志

ABSTRACT

Parkinson′s disease (PD) is the second most common neurodegenerative disease. It is mainly characterized by resting tremor, muscle rigidity, and akinesia. Interestingly, under certain conditions, such as fear, visual stimulation, etc., PD patients could temporarily restore normal motor function, which is called paradoxical kinesia in PD. This article makes comments on the manifestations, possible mechanisms, and clinical significance of paradoxical kinesia in PD. Attempt was also made to put forward the limitations and controversies of this phenomenon, which is helpful for more research to further clarify the pathogenesis behind this phenomenon.
