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: The participants were instructed to imagine waving with their right hand with a frequency of about 0.5 Hz as soon as they saw the execution cue. A scale, providing a continuous on-line information about MI, was shown in the left upper corner of the screen (Fig. 2). It was explained to participants that the FES would be activated when the indicator of the scale reached zero. They were not specifically instructed to look at the indicator, and could choose to concentrate on either the scale or on their own hand while imagining moving their right hand. Therefore for conditions 1 and 2 the participants voluntarily activated the FES using kinaesthetic MI.
