Influence of motor imagination on cortical activation during functional electrical stimulation.
Bottom Line: Event related synchronisation/desynchronisation (ERS/ERD) over the sensory-motor cortex was analysed and compared in three paradigms: MI before FES, MI before and during FES and FES alone activated automatically.When MI only preceded FES it resulted in a weaker beta ERD during FES than when FES was activated automatically.The study is relevant for neurorehabilitation of movement.

Mentions: Fig. 5 shows ERS/ERD maps for all three experimental conditions (left column) and areas of statistical significant differences in the time–frequency domain between all three conditions (right column) at electrode location CFz-CPz. The weakest ERD upon FES can be noticed for condition 1, significantly lower than in condition 2 (Fig. 5d) over the 8–16 Hz band and lower than condition 3 in the higher beta band (Fig. 5e). Although visually, condition 2 seems to have stronger ERD than condition 3 (Fig. 5f), statistical analysis revealed significant differences mostly in the period before FES. Post FES beta ERD is followed by beta ERS and is most prominent for condition 3.
