Novel Stimulation Patterns to Improve the Effectiveness of Spinal Cord Stimulation

Exclusion Criteria17

• Patient exhibits catastrophization based on physician evaluation (e.g., average overall daily pain intensity of 100 on a 0-100mm visual analog scale, every day during the 7 days prior to Screening, based on patient recall
• Pain originating from peripheral vascular disease
• Active treatment for cancer in past 6 months
• Involved in disability litigation
• High surgical risk including documented history of allergic response to titanium or silicone, current systemic infection, or local infection in close proximity to anticipated surgical field
• Body mass index ≥ 45 at Screening
• Terminal illness with anticipated survival \< 12 months
• Participant is immunocompromised
• Significant cognitive impairment at Screening that, in the opinion of the Investigator, would reasonably be expected to impair the study candidate's ability to participate in the study
• Participating (or intends to participate) in another drug or device clinical trial that may influence the data that will be collected for this study
• Previous spinal cord stimulation trial/implant or is already implanted with an active implantable device(s) (e.g. drug pump, implantable pulse generator)
• A pregnant female or a female of childbearing potential planning to get pregnant during the course of the study
• Plan to receive any massage or manipulation directly over the leads or by the anticipated location of the IPG or treatments that involve sudden jerking motions of the torso at any
• Existing medical condition that is likely to require the use of diathermy
• Any injury or medical/psychological condition that might be significantly exacerbated by the implant surgery or the presence of an implantable stimulator or otherwise compromise subject safety
• Unable to operate the study devices including wrist-worn biosensor and mobile app
• Documented history of substance abuse or dependency in the 6 months prior to baseline
