1. A method for providing an electrical neurostimulation therapy to a patient using an implantable medical device, comprising:

  • determining a first rate of change of an amplitude of a first ramping portion of an electrical signal, wherein the first ramping portion is a portion where the amplitude is changed prior to delivery of a therapeutic level of stimulation;

    delivering the electrical signal comprising the first ramping portion with the first rate of change of the amplitude and the therapeutic level of stimulation to a target location of a patient'"'"'s body;

    analyzing efficacy data of the therapy applied using the electrical signal;

    modifying the electrical signal by modifying the first rate of change of the amplitude of the first ramping portion using the efficacy data to create a modified electrical signal with the therapeutic level of stimulation and a modified ramping portion comprising a second rate of change of the amplitude;

    delivering the modified electrical signal with the modified ramping portion and the therapeutic level of stimulation to the target location of the patient'"'"'s body.
