A neuromodulation system executes a set of startup operations. In response to completion of the startup operations, a priming field is automatically initiated. The priming field is to produce a priming effect in priming-targeted neural tissue, with the priming effect causing a change in sensitization to a therapeutic neuromodulation field of the priming-targeted neural tissue. The system also generates the therapeutic neuromodulation field to produce a therapeutic effect in therapy-targeted neural tissue.

A neuromodulation device is configured with a set of testing program configuration instructions including therapeutic neuromodulation field-setting parameters. The device determines a custom priming program in response to the testing program configuration instructions. The custom priming program controls the neuromodulation device to generate a priming field with specific correspondence to the therapeutic neuromodulation field to be produced by the testing program.
