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. 4 shows ERS/ERD maps for all three experimental conditions (left column) and areas of statistical significant differences in the time–frequency domain between the conditions (right column) at electrode location CF4-CP4. Weak ERD can be noticed during FES in both conditions 1 and 3, indicating that FES does not affect the ipsilateral cortex very much. Prominent ERD during FES can be noticed for condition 2. Therefore statistical significant differences were larger between conditions 1 and 2, and 2 and 3 (Fig. 4d and f) than between conditions 1 and 3 (Fig. 4e).
