What researchers measure

Primary outcomes

  1. Low Back Pain Responder Rate

    Proportion of subjects with an improvement of 20 mm during the last 7 days for low back pain at 6 months, 1 year, 2 years, and 3 years post-procedure compared with Baseline (VAS)

    Time frame: Up to 3 years post-procedure

  2. Left Leg Pain Responder Rate

    Proportion of subjects with an improvement of 20 mm during the last 7 days for left leg pain at 6 months, 1 year, 2 years, and 3 years post-procedure compared with Baseline (VAS)

    Time frame: Up to 3 years post-procedure

  3. Right Leg Pain Responder Rate

    Proportion of subjects with an improvement of 20 mm during last 7 days for left leg pain at 6 months, 1 year, 2 years, and 3 years post-procedure compared with Baseline (VAS)

    Time frame: Up to 3 years post-procedure

Other outcomes

  1. Percent Low Back Pain Relief

    Percent Low Back Pain Relief at 6 months, 1 year, 2 years and 3 years post-procedure compared with Baseline (PPR). PPR is a questionnaire assessing how much of the subject's low back pain has been relieved by treatment. Pain relief is expressed as a percentage from 0 - 100%.

    Time frame: Up to 3 years post-procedure

  2. Quality of Life (QoL)

    Percent of change from Baseline index score to the Follow-up timepoints index score using EQ-5D-5L. EuroQol Five Dimensions Five Level questionnaire (EQ-5D-5L) is comprised of a descriptive system and a visual analog scale (VAS). The descriptive system measures quality of life along five dimensions, including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, with five levels for each dimension from which subjects are asked to select one. VAS is used to record the subject's self-rated health on a 20cm vertical line with endpoints labeled 'the best health you can imagine' and 'the worst health you can imagine'. To calculate the Index Value, responses are converted into a single score using a specific algorithm. Score ranges from 0.000 (representing death) to 1.000 (representing perfect health). The algorithm is based on public preferences, reflecting how different health states are valued by the general public.

    Time frame: Up to 3 years post-procedure

Adverse events

Collected over From the time a subject sign the PRESS 2 Study Informed Consent through 3-year visit or study withdrawal. Patients include previously implanted subjects and newly enrolled subjects up to 3 years post-procedure. Data for patients previously implanted includes retrospective data however adverse events were monitored/assess from the time a subject signed the PRESS 2 Study Informed Consent through study completion.. Non-serious events are listed at a 0% frequency threshold.
