A fully implanted programmable stimulator based on wireless communication for epidural spinal cord stimulation in rats

► We investigated the motor effects of epidural spinal cord stimulation. ► We developed a low cost, easily built implantable epidural spinal cord stimulation system for animal experiments. ► In vivo test, we implanted the stimulators into three Sprague-Dawley rats to validate the function of the stimulators. ► We investigated different motor effects caused by varying stimulation parameters in rats.
