Results: Seventy-five of 110 assigned treatment group; complete diary available for 66. responder defined as subject who achieved 50% greater reduction number month three-point average overall pain intensity compared with baseline. Three-month rates 39% AS, 6% PS 0% MM. No unanticipated adverse device events occurred. Lead migration occurred 12 51 (24%) subjects.
