Abstract
Patients with spinal cord injuries have benefited from neurostimulation therapy comprising delivery of electrical stimulation to enable or excite neurological responses using an implantable neurostimulator having an electrode array. Dangerous levels of charge are avoided while providing multiple, simultaneous stimulation waveforms by inducing a short in an electrode when a monitored value reaches or exceeds a predetermined threshold.

A method for controlling neurostimulation charge, comprising:
- determining, for an electrode array including a plurality of electrodes and being configured to produce at least two simultaneous waveforms, at least one of a charge, a charge density, a residual charge, a voltage and a k value on at least one of the plurality of electrodes;
- and
- inducing a short in the at least one electrode when the charge, charge density, residual charge, voltage or k value reaches or exceeds a predetermined threshold.
