    Abstract: New waveforms for use in an implantable pulse generator or external trial stimulator are disclosed which mimic actively-driven biphasic pulses, and which are particularly useful for issuing low frequencies pulses. The waveforms comprise at each electrode interleaved first and second pulses. Each first pulse comprises a first monophasic pulse and a first passive charge recovery period. Each second pulse comprises a second monophasic pulse with a polarity opposite the first monophasic pulse and a second passive charge recovery period. Preferably, the amplitudes and pulse widths of the first and second monophasic pulses are equal, or at least charge balanced at each electrode. The first and second monophasic pulses mimic the functionality of a symmetric biphasic pulse, with the first monophasic pulse mimicking the functionality of the biphasic pulse's first phase, and the with the second monophasic pulse mimicking the functionality of the biphasic pulse's second phase.

    Abstract: Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which active electrodes are selected for the patient. This allows sweet spot searching to occur much more quickly and without the need to wash in the various electrode combinations that are tried. After selecting electrodes using supra-perception therapy, therapy is titrated to sub-perception levels using the selected electrodes. Such sub-perception therapy has been investigated using pulses at or below 10 kHz, and it has been determined that a statistically significant correlation exists between pulse width (PW) and frequency (F) in this frequency range at which SCS patients experience significant reduction in symptoms such as back pain. Beneficially, sub-perception stimulation at such low frequencies significantly lowers power consumption in the patient's neurostimulator.

    Abstract: An example of a system for controlling delivery of neurostimulation from a stimulation device to a patient according to a selected neurostimulation program may include a programming device. The programming device may be configured to be communicatively coupled to the stimulation device and to select the neurostimulation program. The programing device may include a user interface and a program selection circuit. The program selection circuit may be configured to receive life factor information indicative of at least one of an environmental factor and a biopsychosocial factor of the patient, to select the neurostimulation program from a plurality of neurostimulation programs based on the received life factor information, to present a recommendation using the user interface based on the selected neurostimulation program, and to receive a user command responding to the recommendation using the user interface.
