1. A method of blocking a neural axon, comprising:

  • conveying time-varying electrical energy to a blocking site on the neural axon for aninitial phase, wherein the conveyed electrical energy has an amplitude and frequency during the initial phase sufficient to block action potentials from propagating along the neural axon from a location proximal to the blocking site to a location distal to the blocking site; and

    conveying the time-varying electrical energy to the blocking site on the neural axon for a subsequent phase contiguous with the initial phase, thereby treating pain suffered by a patient, wherein the conveyed electrical energy has, during the subsequent phase, a decreased amplitude relative to the initial phase and a frequency known to maintain blocking of the action potentials along the neural axon from the location proximal to the blocking site to the location distal to the blocking site, wherein the initial phase is in the range of 0.1-20 ms.
