Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain Relief in Limb Pain	Percent Pain Relief (PPR) in limb pain using a questionnaire where 100% is complete relief and 0% is no relief in pain compared with Baseline	Up to 12 months follow up
Secondary	Global Impression of Change	Patient global impression of change (PGI-C) at 3-, 6- and 12-Month Assessment Visit where patients use a seven-point scale to assess how much their condition has improved or worsened relative to their baseline. Subjects will rate themselves as: very much improved; much improved; minimally improved; no change; minimally worse; much worse; or very much worse.	Up to 12 months follow up
