" It is still a challenge to delay the onset of fatigue on muscle contraction induced by Functional Electrical Stimulation. We explored the use of two stimulation methods with the same total area, single electrode stimulation, and spatially distributed electrical stimulation during isometric knee extension with spinal cord injured (SCI) volunteers. We applied stimulation on the left and right quadriceps of two SCI participants with both methods and recorded isometric force and evoked electromyography (eEMG). We calculated the force-time integral and eEMG-time integral for each stimulation series and used a linear regression as a measure of decay ratio. Moreover, we also estimated the contribution from each channel from eEMG. "
