NCT03179202

Brief Summary

The purpose of this study is to evaluate the effectiveness of electrical stimulation (low levels of electricity) on low back pain. This study involves the SPRINT Peripheral Nerve Stimulation (PNS) system. The System delivers mild electrical stimulation to the nerves in the low back. The System includes up to four small wires (called "Leads") that are placed through the skin into the muscles in the low back. The wires attach to device(s) worn on the body that deliver stimulation (called Stimulators).

Outcome Measures

Primary Outcomes (2)

  • Number of Subjects That Experienced ≥30% Reduction in Average Low Back Pain Intensity

    All subjects were asked to complete daily diaries to record their average pain intensity on each day of a 7-day period. The pain intensity question was excerpted from the Brief Pain Inventory-Short Form Question 5 (BPI-5). The BPI-5 uses an 11-point numerical rating scale where 0 represents "No Pain" and 10 represents "Pain as bad as you can imagine." For each subject, the mean score for the baseline and end of treatment (EOT) diary periods were calculated and percent reduction was determined. Subjects that achieved ≥30% reduction in pain, were considered successful.

    Baseline and End of Treatment (EOT= 8-weeks post-start of treatment)

  • Number of Subjects That Experienced at Least One Study-Related Adverse Event

    At each study visit following the baseline assessment at Visit 1, subjects were questioned if any changes in their medical status or condition has occurred since their previous visit. If the subject experienced a change that was an adverse event, an Adverse Event Form was completed by the site. The number of subjects that experienced at least one study-related adverse event is reported here.

    Up to 15 months for each subject from baseline to the last study visit

Secondary Outcomes (6)

  • Worst Pain Intensity

    Baseline and End of Treatment (EOT= 8-weeks post-start of treatment)

  • Oswestry Disability Index (ODI)

    Baseline and End of Treatment (EOT= 8-weeks post-start of treatment)

  • Mean Change in Health-Related Quality of Life

    Baseline and End of Treatment (EOT= 8-weeks post-start of treatment)

  • Beck Depression Inventory (BDI-II)

    Baseline and End of Treatment (EOT= 8-weeks post-start of treatment)

  • Patient Global Impression of Change (PGIC) Survey

    8-weeks post-Start of Treatment (SOT)

  • +1 more secondary outcomes

Study Arms (1)

Peripheral Nerve Stimulation

EXPERIMENTAL

All study subjects will have up to 4 Leads placed in their low back, will use the SPRINT Peripheral Nerve Stimulation (PNS) System, and will receive electrical stimulation.

Device: SPRINT Peripheral Nerve Stimulation (PNS) System

Interventions

The SPRINT PNS System is a device which delivers mild electrical stimulation to the muscles in the low back. The System includes up to four small wires (called "Leads") that are placed through the skin into the muscles in the low back. The wires attach to device(s) worn on the body that deliver stimulation (called Stimulators). The PNS System was approved by the FDA for up to 60 days of use for the management of acute and chronic pain, including back pain.
