Abstract OBJECTIVE: To present an in-depth analysis of clinical predictors of outcome including age, sex, etiology of pain, type of electrodes used, duration of pain, duration of treatment, development of tolerance, employment status, activities of daily living, psychological status, and quality of life. Suggestions for treatment of low back pain with a predominant axial component are addressed. We analyzed the complications and proposed remedial measures to improve the effectiveness of this modality. METHODS: Study group consists of 410 patients (252 men, 58 women) with a mean age of 54 years and a mean follow-up period of 97.6 months. All patients were gated through a multidisciplinary pain clinic. The study was conducted over 22 years. RESULTS: The early success rate was 80% (328 patients), whereas the long-term success rate of internalized patients was 74.1% (243 patients) after the mean follow-up period of 97.6 months. Hardware-related complications included displaced or fractured electrodes, infection, and hardware malfunction. Etiologies demonstrating efficacy included failed back syndrome, peripheral vascular disease, angina pain, complex regional pain syndrome I and II, peripheral neuropathy, lower limb pain caused by multiple sclerosis. Age, sex, laterality of pain or number of surgeries before implant did not play a role in predicting outcome. The percentage of pain relief was inversely related to the time interval between pain onset and time of implantation. Radicular pain with axial component responded better to dual Pisces electrode or Specify-Lead implantation. CONCLUSION: Spinal cord stimulation can provide significant long-term pain relief with improved quality of life and employment. Results of this study will be effective in better defining prognostic factors and reducing complications leading to higher success rates with spinal cord stimulation.

Chronic pain has a major impact on sufferers and their families. The associated health care costs are substantial. In the context of increasing prevalence, effective treatment options are ever more important. 10 kHz spinal cord stimulation has been shown to effectively provide pain relief, aid in opioid reduction, and improve quality of life in patients with chronic intractable pain. The present review aims to summarize the clinical evidence related to the use of 10 kHz SCS in chronic back and/or leg pain. We searched the PubMed database between 2009 and 2 June 2020 for articles reporting clinical studies that included at least 10 human subjects permanently treated with a 10 kHz SCS system (Senza® system) for chronic back and/or leg pain for a minimum of 3 months. A randomized controlled trial (SENZA-RCT), as well as several prospective and retrospective studies, reported clinical outcomes in subjects with chronic back and leg pain treated with 10 kHz SCS. A high proportion of subjects (60%–80%) reported long-term response to therapy. Pain relief was provided without paresthesia. Other studies showed promising pain relief outcomes in subjects with back pain ineligible for spinal surgery, neuropathic limb pain, and in those with previously failed traditional low-frequency SCS. Most studies reported improved quality of life metrics and/or reduced opioid intake. Level 1 evidence has already been established for the use of 10 kHz SCS in treating chronic back and leg pain, corroborated by real-world, clinical experience. Exploratory studies also show the potential of the therapy in other refractory pain syndromes, although larger studies are desired to validate their findings. Overall, the literature suggests that 10 kHz SCS provides long-term pain relief in a high proportion of patients, along with improved quality of life and reduced opioid consumption.

Abstract INTRODUCTION Tonic spinal cord stimulation (SCS) mainly modulates the lateral spinothalamic tract relaying information for quality and intensity of pain. In contrast, nonlinear burst stimulation affects the lateral, medial, and descending pain pathways. The medial spinothalamic tract has been associated with emotional and motivational aspects of pain, such as pain catastrophizing and suffering. The objective of this prospective, multi-center, single arm trial was to assess functional and psychosocial outcomes after SCS using a burst stimulation design. METHODS Eligible patients with chronic, intractable pain of the trunk and/or lower limbs were enrolled. After a successful trial period, patients received a permanent SCS implant and returned for follow-up at 6 mo. Quality of life (EQ-5D), mental health (PCS, PHQ-9), and physical function (TSK, PROMIS-8) were recorded. RESULTS 173 patients at 21 centers received a permanent implant. We observed an improvement in all functional and psychosocial outcomes compared to baseline (P < .0001). About 74% of patients achieved a result that was equal to (within 10%) or better than the population norm for at least one outcome measure. Specifically, overall quality of life (EQ-5D) improved from 0.4 to 0.7. Mean pain catastrophizing (PCS) score dropped below the population norm (14); 70% of patients who were clinically catastrophizing (score of ≥30) at baseline, were not at 6 mo. Patients who were moderately or severely depressed at baseline (n = 82) showed a clinically significant improvement to mild depression. Patients displayed an improved physical function and reduced kinesiophobia (TSK). Furthermore, 75% of patients were satisfied or very satisfied with their therapy. Finally, 68% (84/123) reduced their opioid usage at 6 mo. CONCLUSION Our study provides additional support for nonlinear burst SCS by showing this therapy improves patients' mental and physical health and quality of life. These results provide evidence that this stimulation design acts upon motivational-affective responses of pain through the medial spinothalamic tract.

Abstract BACKGROUND: Complex regional pain syndrome (CRPS) I is a debilitating neuropathic pain disorder characterized by burning pain and allodynia. Spinal cord stimulation (SCS) is effective in the treatment of CRPS I in the medium term but its long-term efficacy and ability to improve functional status remains controversial. OBJECTIVE: To evaluate the ability of SCS to improve pain, functional status, and quality of life in the long term. METHODS: We retrospectively analyzed 25 patients over a mean follow-up period of 88 months. The parameters for evaluation were visual analog scale (VAS), Oswestry Disability Index (ODI), Beck Depression Inventory (BDI), EuroQoL-5D (EQ-5D) and Short Form 36 (SF-36), and drug consumption. Evaluations were conducted at point of entry, 3 months, 12 months, and last follow-up at 88 months (mean). RESULTS: At baseline, the mean scores were VAS 8.4, ODI 70%, BDI 28, EQ-5D 0.30, and SF-36 24. In general, maximum improvement was recorded at follow-up at 3 months (VAS 4.8, ODI 45%, BDI 15, EQ-5D 0.57, and SF-36 45). At last follow-up, scores were 5.6, 50%, 19, 0.57, and 40, respectively. Despite some regression, at last follow-up benefits were maintained and found to be statistically significant (P &lt; .001) compared with baseline. Medication usage declined. SCS did not prevent disease spread to other limbs. Best results were achieved in stage I CRPS I, patients under 40 years of age, and those receiving SCS within 1 year of disease onset. CONCLUSION: SCS improves pain, quality of life, and functional status over the long term and consequently merits early consideration in the treatment continuum.

Abstract Purpose Metastatic epidural spinal cord compression (MESCC) is a devastating complication of advanced malignancy, which can result in neurologic complications and significant deterioration in overall function and quality of life. Most patients are not candidates for optimal surgical decompression and as a result, receive urgent 3D conformal radiotherapy (3DCRT) to prevent or attempt to reverse neurologic progression. Multiple trials indicate that response and ambulatory rates after 3DCRT are inferior to surgery. The advent of stereotactic body radiation therapy (SBRT) has created a method with which a “radiosurgical decompression” boost may facilitate improve outcomes for MESCC patients. Methods We are conducting a pilot study to investigate SBRT boost after urgent 3D CRT for patients with MESCC. The aim of the study is to establish feasibility of this two-phase treatment regimen, and secondarily to characterize post-treatment ambulation status, motor response, pain control, quality of life and survival. Discussion We describe the study protocol and present a case report of one patient. A quality assurance review was conducted after the first seven patients, and resultant dose-constraints were revised to improve safety and feasibility of planning through more conservative organ at risk constraints. There have been no severe adverse events (grade 3–5) to date. We have illustrated clinical and dosimetric data of an example case, where a patient regained full strength and ambulatory capacity. Conclusions Our study aims to determine if SBRT is a feasible option in addition to standard 3DCRT for MESCC patients, with the goal to consider future randomized trials if successful. Having a robust quality assurance process in this study ensures translatability going forward if future trials with multicenter and increased patient representation are to be considered.
