Systems and methods with activating recharge stimulation

A non-transitory machine-readable medium including instructions, which when executed by a machine, cause the machine to perform a method comprising:

• delivering an electrical waveform using at least one electrode contact, wherein the electrical waveform includes first phases of a first polarity and second phases of a second polarity opposite the first polarity, wherein the delivering the electrical waveform includes therapeutically stimulating neural tissue using both the first phases and the second phases of the electrical waveform, and using the second phases to reduce built up charge from the at least one electrode contact caused by the first phases and using the first phases to reduce built up charge from the at least one electrode contact caused by the second phases.

A system, comprising:

• a neurostimulation system including at least one electrode contact and a neurostimulator configured to use the at least one electrode contact to deliver a stimulation therapy to a patient using an electrical waveform that includes first phases of a first polarity and second phases of a second polarity opposite the first polarity, wherein the neurostimulator is configured to deliver the stimulation therapy by therapeutically stimulating neural tissue using the both the first phases and the second phases of the electrical waveform, the second phases remove built up charge from the at least one electrode contact caused by the first phases, and the first phases remove built up charge from the at least one electrode contact caused by the second phases.
