Movement related evoked potentials in Parkinson’ s disease patients and healthy controls

The aim of this study was to demonstrate the role of movement related evoked cortical potentials (MREP) in Parkinson’ s disease (PD) diagnostics. The experiment consisted of repeated spontaneous thumb movements in a time interval of 5-10 s. There were two groups of subjects, PD patients and healthy controls. We observed shift in the latency of the beginning of MREP, the ereitschaftpotential (BP), in patients with PD. The BP started earlier for healthy controls than for the PD patients when the PD patient’ s affected hand movement was observed. The BP latency shift was observed for the affected hand, but the beginning of the BP was not influenced for the healthy hand. The later components of MREP were not significantly influenced. The PD patients group was diverse and in accordance with that the standard deviations of MREP components’ amplitudes for this group was much greater that for the controls group.
