Objective: BurstDR™ stimulation can affect lateral und medial aspects of the pain matrix. However, also affective-cognitive aspects are important. We used different questionnaires which addressed specifically different affective-cognitive aspects of the pain processing and investigated to which degree they were altered by the use of BurstDR™ stimulation.

Methods: Patients (age >18 years) with chronic pain in the back or the extremities were retrospectively examined. After a successful test-trial (duration of 3–14 days, pain decrease >50%), a permanent generator was implanted. The patients were re-examined after 6–23 months (median 10,6 months). In this study the sole use of constant BurstDR™ stimulation was evaluated. We used the Numeric Rating Scale (NRS), the Chronic Pain Acceptance Questionnaire (CPAQ), the Pain Disability Index (PDI), the Pain Catastrophizing Scale (PCS), the Beck Depression Inventory II (BDI-II) and the Pain Vigilance and Awareness Questionnaire (PVAQ) for our assessments.

Results: We included 41 consecutive patients (22 female, 19 male, mean age 56 years, with an age range from 23–78 years, 41/36 to permanent conversion) during the time period from March 2014 until August 2016. The patients presented with FFBS (46,3%), CRPS (22%), foot or leg pain (19,5%) and other pain diagnoses (12,2%). Thirty six patients had a successful test-trial and a generator was subsequently implanted. The NRS dropped from Mdn=9 to Mdn=5 (p=0.001). The PDI decreased from Mdn=48 to Mdn=43 (p=0.004). The PCS decreased from Mdn=29 to Mdn=22 (p=0.02). The CPAQ increased from Mdn=35 to Mdn=44 (p=0.031). The BDI-II decreased from Mdn=21 to Mdn=17 (p=0.016). The PVAQ dropped from Mdn=51 to Mdn=43 (p=0,017). There was a significant positive correlation between PCS, CPAQ and PVAQ (ρ=0,555). The strongest correlation was found between BDI-II and PCS (ρ=0,833 at T1, ρ=0,874 at T0).

Conclusion: The combined use of CPAQ, PCS and PVAQ allows an assessment of affective-cognitive aspects of the pain matrix. The comparison of the combined values pre and post stimulation revealed a significant improvement during BurstDR™ stimulation. There was also an improvement regarding anxiety and depression. The correlations between the different tests showed that BurstDR™ stimulation did not only seem to have an impact on emotional aspects of the pain processing but also on affective-cognitive ones.
