NCT04244669

Brief Summary

Prospective, randomized, multicentre, parallel, controlled, and double-blind trial. It is a study with 2 groups with evaluation pre and post treatment with Spinal Cord Stimulation (SCS) implantation of patients with Failed Back Surgery Syndrome (FBSS). The study has been designed to assess primarily non-inferiority and secondarily superiority of SCS DTM therapy

Outcome Measures

Primary Outcomes (1)

  • Non-inferiority VAS

    Non-inferiority of SCS DTM therapy compared with low frequency SCS in change of quantitative measure of pain with Visual Analogue Scale (VAS, 0-10 points, no pain to the worst pain imaginable).

    3, 6,12 months

Secondary Outcomes (13)

  • Superiority VAS

    3, 6,12 months

  • Correlation between VAS and functionality and quality of life scores

    3, 6,12 months

  • Objective measure of activity parameters

    3, 6,12 months

  • Qualitative measure of dream quality

    3, 6,12 months

  • Scores/Questionnaires of disability: ODI

    3, 6,12 months

  • +8 more secondary outcomes

Study Arms (2)

SCS with Conventional Stimulation

EXPERIMENTAL

In this group, a conventional stimulation with low frequency will be tried. It will be programmed according to the usual clinical practice looking for one or more combinations of poles that allow a coverage of paraesthesia with a conventional stimulation of at least 80% of the painful area. This programming will be modified until getting not only 80% coverage but also a decrease of at least 50% of pain in that area.

Device: IPG with Conventional Stimulation

SCS with SCS DTM Stimulation

EXPERIMENTAL

IIn this group the SCS DTM™ workflow will be programmed. Each SCS DTM™ program group has at least two programs with different pulse rate in the 20 to 1,200 Hz range and each having a maximum pulse width of 1ms.

Device: IPG with SCS DTM

Interventions

In this group, a conventional stimulation with low frequency will be tried. It will be programmed according to the usual clinical practice looking for one or more combinations of poles that allow a coverage of paraesthesia with a conventional stimulation of at least 80% of the painful area. This programming will be modified until getting not only 80% coverage but also a decrease of at least 50% in that area. It can be reprogrammed as many times as necessary during the 14-21 days of margin.
