Influence of motor imagination on cortical activation during functional electrical stimulation.

Reynolds C, Osuagwu BA, Vuckovic A - Clin Neurophysiol (2014)

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.

Experimental paradigms for conditions 1–3 for the on-line BCI control of FES. The period of MI is of variable duration, maximum duration 10 s. The preparation period in conditions 1 and 2 lasted 3 s and FES was always applied for 4 s.

f0005: Experimental paradigms for conditions 1–3 for the on-line BCI control of FES. The period of MI is of variable duration, maximum duration 10 s. The preparation period in conditions 1 and 2 lasted 3 s and FES was always applied for 4 s.

Mentions: There were three conditions in which the FES was activated (Fig. 1). In the first condition, participants had to perform MI of the right hand to activate the FES and stop MI as soon as the FES was activated. In the second condition, participants were instructed to perform MI of the right hand to activate the FES and to carry on with the MI while the FES was active. In the third condition, they were not required to perform MI but FES was automatically activated.
