This means that the effect can be localized. Furthermore, turning off the current may eliminate the effect. Alternatively, currents can be delivered in such a way as to make the effect longer lasting by taking advantage of the inherent plasticity of the nervous system. Next, the electrical stimulation is incredibly efficient. An extraordinarily small amount of current can generate enough muscle activation to lift the body.
Electrical stimulation is also rapid acting, with the effect being observed in seconds.
Finally, electrical stimulation can be applied safely. Methods for delivering current to biological tissue have been determined through careful science and testing. Safe stimulating waveforms that employ bi-directional pulses with charge densities below established limits are well tolerated by the tissue. Thus, electrical stimulation is an extraordinarily versatile, effective, and safe tool for manipulation of activity of the nervous system. Electrical stimulation impacts neural rehabilitation in many ways and at different time scales.
