In various embodiments electrical stimulators are provided for transcutaneous and/or epidural stimulation. In certain
embodiments the stimulator provides one or more channels configured to provide one or more of the following stimulation patterns:
i) monophasic electrical stimulation with a DC offset; ii) monophasic electrical stimulation with charge balance; iii) delayed biphasic
electrical stimulation with a DC offset; iv) delayed biphasic electrical stimulation with charge balance ;v) amplitude modulated dynamic
stimulation; and/or vi) frequency modulated dynamic stimulation.
