Arm Intervention/treatment
Experimental: Neurostimulation for chronic pain
Neurostimulation (spinal cord stimulation with or without peripheral nerve stimulation of the trunk) for chronic intractable pain of the trunk and/or limbs.
Device: Neurostimulation device implantation

Study subjects will undergo a screening-trial of neurostimulation using the Boston Scientific Corporation Precision Spectra neurostimulation system and may proceed to permanent implantation in the event of a successful screening trial.

Treatment will include spinal cord stimulation and may also include peripheral nerve stimulation, based upon the physician's subject-specific treatment plan.

Primary Outcome Measures :
  1. Proportion of Subjects Satisfied With Treatment at 90 Days Post-IPG Implantation [ Time Frame: 90-days post permanent implantation ]
    Proportion of subjects satisfied with treatment at 90 days post-IPG implantation, as measured by a 7-point Patient Satisfaction with Treatment (PSWT) questionnaire.

  2. Proportion of Subjects Satisfied With Treatment in a Sub-group Utilizing More Than 2 IPG Ports at 365 Days Post-IPG Implantation [ Time Frame: 365 days post permanent implantation ]
    Proportion of subjects in a sub-group utilizing more than 2 IPG ports at 365 Days post-IPG implantation satisfied with treatment, as measured by a 7-point Patient Satisfaction with Treatment (PSWT) questionnaire.
