About this trial

The goal of this study is to compare pain outcomes achieved by spinal cord stimulation (SCS) using time varying stimulation patterns with pain outcomes achieved by current standard of care SCS.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Ability to provide informed consent

Age ≥ 22

Chronic pain of the trunk and/or limbs for at least 6 months

Baseline average daily overall pain score of >60 (on a scale of 0-100mm) on the Visual Analog Scale related to pain of the back and/or limbs

Disqualifiers

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

Trial design

Design model

Crossover

Treatments tested in this trial

  • Spinal Cord Stimulator

    Device

    Spinal Cord Stimulator modified to deliver Time Variant Pulse (TVP) stimulation.

  • Spinal Cord Stimulator

    Device

    Spinal Cord Stimulator to deliver standard of care Time Invariant Pulse (TIP) stimulation.

Treatment groups

43 Participants
are divided into 2 treatment groups
Group A: Time Invariant Pulse(TIP) StimulationActive comparator 1 intervention
Group B: Time Variant Pulse (TVP) StimulationExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Change in Patient responder rate

The primary endpoint for this trial will be a comparison of the percentage of patients achieving at least a 50% reduction in pain during the TIP stimulation block with the percentage of patients achieving at least a 50% reduction in pain during either TVP stimulation block.

Time frame
Patient responder rate will be measured from the baseline and during three experimental stimulation periods which are 8±3 weeks each.
