Abstract: Systems and methods are provided for electrical stimulation using electrical neurostimulators to treat neurological disorders. In exemplary implementations, the systems and methods effectuate selective sensory transmission block by spatially and temporally patterned multichannel, closed-loop electrical stimulation of neural tissue across the intervertebral foramina. The systems and methods optimize stimulation parameters according to the conduction velocity of afferents leading to effective neural transmission block. The systems and methods provide a dramatic improvement of selective transmission block, e.g., in a sub-population of unmyelinated C-fibers and slow-conducting A? fibers, by combining spatial, frequency and temporal parameters in the disclosed stimulation paradigm. An optimized start and termination of the stimulation may be implemented, as desired, thereby reducing overall energy consumption by reducing the stimulus strength during the maintenance phase of neural transmission block.
