摘要
Disclosed are systems and methods for providing stimulation using waveforms with long duration phases in a spinal cord stimulator. Simulation shows the effectiveness of using phase durations of greater than 2.0 ms, or even 2.6 ms or greater, in recruiting inhibitory interneurons in the dorsal horn of the spinal cord, or in recruiting dorsal column axons of the dorsal column, both of which promote pain suppression in spinal cord stimulation (SCS) patients. Traditional SCS devices may not allow the programming of phase durations of such lengths, and so examples of how long phase durations can be effectively created is shown by way of a non-limiting example, preferably in a single timing channel. The waveforms preferably have at least two phases of opposite polarities, at least one of which is long, although phases may be split into sub-phases. The waveforms may be charge balanced at each electrode.
