Abstract Objective Autonomic nervous system dysfunction has been implicated in chronic whiplash-associated disorder (WAD). However, the relationship between autonomic variables (e.g., resting heart rate and blood pressure) and clinical factors in chronic WAD is not well understood. This study sought to examine the associations between resting heart rate, resting blood pressure, pain processing and psychological variables in chronic WAD and in pain-free controls. Design Secondary analysis of a cross-sectional study. Setting University clinical research laboratory. Subjects Thirty-six people with chronic WAD Grade II (mean [SD] age 40.1 [14.6] years, 28 females) and 25 pain-free controls (35.6 [13.0] years, 17 females). Methods Participants had resting heart rate, systolic and diastolic blood pressure measured. Pain processing measures comprised: (i) pain pressure threshold at the cervical spine, hand and leg, (ii) temporal summation at the cervical spine and hand, and (iii) conditioned pain modulation. Psychological outcomes included measures of kinesiophobia, pain catastrophizing and post-traumatic stress symptoms. Correlations between autonomic variables, pain processing and psychological variables were determined (P < .05, 5% FDR). Results No significant correlations between autonomic and pain processing variables, or autonomic and psychological variables were found in the chronic WAD group. In the control group, diastolic blood pressure was positively correlated with cervical spine pressure pain threshold (r = 0.53, P = .007). Conclusions An association between blood pressure and pain sensitivity was observed in the control group but not the chronic WAD group. Such an association appears to be disrupted in chronic WAD, which may infer involvement of autonomic pathways in the pathophysiology of this condition.
摘要目的自主神经系统功能障碍与慢性鞭扭伤相关疾病(WAD)有关。然而，自主变量(如静息心率和血压)与慢性WAD临床因素之间的关系尚不清楚。本研究旨在研究慢性WAD和无痛对照患者的静息心率、静息血压、疼痛处理和心理变量之间的关系。设计横断面研究的二次分析。大学临床研究室。慢性WAD II级患者36例(平均[SD]年龄40.1[14.6]岁，女性28例)，无痛对照25例(35.6[13.0]岁，女性17例)。方法测量参与者静息心率、收缩压和舒张压。疼痛处理措施包括:(i)颈椎、手和腿的痛压阈值，(ii)颈椎和手的颞统，以及(iii)条件疼痛调节。心理结果包括运动恐惧症、疼痛灾难和创伤后应激症状的测量。自主神经变量、疼痛加工和心理变量之间的相关性(P <。5.05, 5%罗斯福)。结果慢性WAD组自主神经与疼痛加工变量、自主神经与心理变量之间无显著相关性。对照组患者舒张压与颈椎压痛阈呈正相关(r = 0.53, P = 0.007)。结论:在对照组中观察到血压与疼痛敏感性之间的相关性，而在慢性WAD组中没有。这种关联似乎在慢性WAD中被破坏，这可能推断自主神经通路参与了这种情况的病理生理。

Abstract Objectives The plethora of self-administered questionnaires to assess positive psychosocial factors complicates questionnaire selection. This study aimed to identify and reach consensus on the most suitable self-administered questionnaires to assess resilience, optimism, pain acceptance and social support in people with pain. Design A three-round modified Delphi study. Participants Forty international experts. Methods In Round 1, the experts suggested questionnaires deemed appropriate to assess resilience, optimism, pain acceptance and/or social support. In Round 2, experts indicated whether they considered the suggested questionnaires to be suitable (Yes/No/Don’t know) to assess these psychosocial factors, taking into consideration content, feasibility, personal experience and the measurement properties which we provided for each questionnaire. Questionnaires that were considered suitable by the majority of experts (≥60%) were retained for Round 3. In Round 3, the suitability of each questionnaire was rated on a 0–10 Likert scale. Consensus was reached if ≥75% of experts rated the questionnaire ≥7. Results From the 67 questionnaires suggested in Round 1, one questionnaire could be recommended per domain. For resilience: Pain Resilience Scale; for optimism: Revised Version of the Life Orientation Test; for pain acceptance: 8-item and Revised Versions of the Chronic Pain Acceptance Questionnaire; for social support: Emotional Support Item Bank of the PROMIS tool. Consensus for these questionnaires was also reached in a sensitivity analysis which excluded the ratings of experts involved in the development, translation and/or validation of relevant questionnaires. Conclusion We advocate the use of these recommended questionnaires so data can be compared and pooled more easily.

Abstract Background A crisis in pain management persists, as does the epidemic of opioid overdose deaths, addiction, and diversion. Pain medicine is meeting these challenges by returning to its origins: the Bonica model of multidisciplinary pain care. The 2018 Academic Consortium White Paper detailed the historical context and magnitude of the pain crisis and the evidence base for nonpharmacologic strategies. More than 50% of chronic opioid use begins in the acute pain care setting. Acupuncture may be able to reduce this risk. Objective This article updates the evidence base for acupuncture therapy for acute pain with a review of systematic reviews and meta-analyses on postsurgical/perioperative pain with opioid sparing and acute nonsurgical/trauma pain, including acute pain in the emergency department. Methods To update reviews cited in the 2018 White Paper, electronic searches were conducted in PubMed, MEDLINE, CINAHL, and the Cochrane Central Register of Controlled Trials for “acupuncture” and “acupuncture therapy” and “acute pain,” “surgery,” “peri-operative,” “trauma,” “emergency department,” “urgent care,” “review(s) ,” “systematic review,” “meta-analysis,” with additional manual review of titles, links, and reference lists. Results There are 22 systematic reviews, 17 with meta-analyses of acupuncture in acute pain settings, and a review for acute pain in the intensive care unit. There are additional studies of acupuncture in acute pain settings. Conclusion The majority of reviews found acupuncture therapy to be an efficacious strategy for acute pain, with potential to avoid or reduce opioid reliance. Future multicenter trials are needed to clarify the dosage and generalizability of acupuncture for acute pain in the emergency department. With an extremely low risk profile, acupuncture therapy is an important strategy in comprehensive acute pain care.

Abstract Objectives Although complex pain conditions require an interdisciplinary approach, employment services are rarely provided in pain centers. Individual Placement and Support (IPS) is an effective approach to increase work participation among patients with severe mental illness, and recent evidence suggests that this method can be successfully repurposed for new target groups. We aimed to investigate the effectiveness of IPS integrated with interdisciplinary treatment as usual (TAU) for patients with chronic pain in a tertiary pain center. Methods A randomized controlled trial comparing IPS integrated with TAU (n = 38) with TAU alone (n = 20) was conducted. Participants were patients with chronic pain who were 18–65 years of age and currently on long-term sick leave or disability benefits or unemployed. The primary outcome was employment within 12 months after enrollment, with additional long-term follow-up after 24 months. Secondary outcomes included health and quality of life, measured at baseline, 6 months, and 12 months. Results During 12-month follow-up, 52.8% in the IPS group and 38.9% in the TAU group had attained employment. The difference increased during 24-month follow-up but did not reach statistical significance. Findings on secondary outcomes were generally nonsignificant. Conclusions The IPS in Pain trial is the first study to evaluate the effect of IPS for patients with chronic pain conditions. It shows that IPS can be integrated into the daily practice of interdisciplinary pain treatment, with employment rates exceeding 50% in 1 year and a clear trend in favor of the IPS group. Results did not, however, reach significance. Larger randomized controlled trials are needed to draw clear conclusions about effectiveness.
虽然复杂的疼痛条件需要跨学科的方法，就业服务很少在疼痛中心提供。个体安置和支持(IPS)是提高严重精神疾病患者工作参与度的有效方法，最近的证据表明，这种方法可以成功地用于新的目标群体。我们的目的是研究IPS结合跨学科治疗(TAU)对三级疼痛中心慢性疼痛患者的有效性。方法采用随机对照试验，将IPS联合TAU (n = 38)与TAU单独(n = 20)进行比较。参与者是18-65岁的慢性疼痛患者，目前正在长期病假或残疾福利或失业。主要结果是入组后12个月内的就业，24个月后进行额外的长期随访。次要结局包括健康和生活质量，在基线、6个月和12个月时测量。结果随访12个月，IPS组和TAU组分别有52.8%和38.9%的患者就业。随访24个月，差异有所增加，但无统计学意义。次要结局的发现一般不显著。结论IPS in Pain试验是首个评估IPS对慢性疼痛患者疗效的研究。这表明IPS可以融入跨学科疼痛治疗的日常实践，1年内就业率超过50%，IPS组有明显的优势趋势。然而，结果并没有达到显著性。需要更大规模的随机对照试验来得出关于有效性的明确结论。

Abstract Objective There are several treatment options for patients suffering from lumbar spinal stenosis, including surgical and conservative care. Interspinous spacer decompression using the Superion device offers a less invasive procedure for patients who fail conservative treatment before traditional decompression surgery. This review assesses the current cost-effectiveness, safety, and performance of lumbar spinal stenosis treatment modalities compared with the Superion interspinous spacer procedure. Methods EMBASE and PubMed were searched to find studies reporting on the cost-effectiveness, safety, and performance of conservative treatment, including medicinal treatments, epidural injections, physical therapy, and alternative methods, as well as surgical treatment, including laminectomy, laminectomy with fusion, and interspinous spacer decompression. Results were supplemented with manual searches. Results Despite substantial costs, persistent conservative treatment (>12 weeks) of lumbar spinal stenosis showed only minimal improvement in pain and functionality. When conservative treatment fails, surgery is more effective than continuing conservative treatment. Lumbar laminectomy with fusion has considerably greater cost than laminectomy alone, as the length of hospital stay increases, the costs for implants are substantial, and complications increase. Although laminectomy and the Superion have comparable outcomes, the Superion implant is positioned percutaneously. This approach may minimize the direct and indirect costs of outpatient rehabilitation and absenteeism, respectively. Conclusions Superion interspinous lumbar decompression is a minimally invasive procedure for patients with lumbar spinal stenosis who have failed conservative treatment. Compared with extending conservative treatment or traditional spinal surgery, interspinous lumbar decompression reduces the direct and indirect costs associated with lumbar spinal stenosis.

Abstract Objective Lumbar spinal stenosis (LSS) is a degenerative spinal condition affecting nearly 50% of patients presenting with lower back pain. The goal of this review is to present and summarize the current data on how LSS presents in various populations, how it is diagnosed, and current therapeutic strategies. Properly understanding the prevalence, presentation, and treatment options for individuals suffering from LSS is critical to providing patients the best possible care. Results The occurrence of LSS is associated with advanced age. In elderly patients, LSS can be challenging to identify due to the wide variety of presentation subtleties and common comorbidities such as degenerative disc disease. Recent developments in imaging techniques can be useful in accurately identifying the precise location of the spinal compression. Treatment options can range from conservative to surgical, with the latter being reserved for when patients have neurological compromise or conservative measures have failed. Once warranted, there are several surgical techniques at the physician’s disposal to best treat each individual case.

Abstract Objective Lumbar spinal stenosis (LSS) can lead to compression of the neural and vascular elements and is becoming more common due to degenerative changes that occur because of aging processes. Symptoms may manifest as pain and discomfort that radiates to the lower leg, thigh, and/or buttocks. The traditional treatment algorithm for LSS consists of conservative management (physical therapy, medication, education, exercise), often followed by epidural steroid injections (ESIs), and when nonsurgical treatment has failed, open decompression surgery with or without fusion is considered. In this review, the variables that should be considered during the management of patients with LSS are discussed, and the role of each treatment option to provide optimal care is evaluated. Results This review leads to the creation of an evidence-based practical algorithm to aid clinicians in the management of patients with LSS. Special emphasis is directed at minimally invasive surgery, which should be taken into consideration when conservative management and ESI have failed.

Abstract Objective Objective Interspinous process spacers are used in the treatment of lumbar spinal stenosis by preventing extension at the implanted level and reducing claudication, which is a common symptom of lumbar spinal stenosis. This review assessed the current safety and performance of lumbar spinal stenosis treatments and the biomechanical effects of spinal position, range of motion, and the use of interspinous process spacers. Method Method EMBASE and PubMed were searched to find studies reporting on the safety and performance of nonsurgical treatment, including physical therapy and pharmacological treatment, and surgical treatment, including direct and indirect lumbar decompression treatment. Results were supplemented with manual searches to include studies reporting on the use of interspinous process spacers and the review of biomechanical testing performed on the Superion device. Results Results The effects of spinal position in extension and flexion have been shown to have an impact in the variation in dimensions of the spinal canal and foramina areas. Overall studies have shown that spinal positions from flexion to extension reduce the spinal canal and foramina dimensions and increase ligamentum flavum thickness. Biomechanical test data have shown that the Superion device resists extension and reduces angular movement at the implantation level and provides significant segmental stability. Conclusions Conclusions Superion interspinous lumbar decompression is a minimally invasive, low-risk procedure for the treatment of lumbar spinal stenosis, which has been shown to have a low safety profile by maintaining sagittal alignment, limiting the potential for device dislodgment or migration, and to preserve mobility and structural elements.

This review assessed the current safety and performance of lumbar spinal stenosis treatments and the biomechanical effects of spinal position, range of motion, and the use of interspinous process spacers. Method Method EMBASE and PubMed were searched to find studies reporting on the safety and performance of nonsurgical treatment, including physical therapy and pharmacological treatment, and surgical treatment, including direct and indirect lumbar decompression treatment. Results were supplemented with manual searches to include studies reporting on the use of interspinous process spacers and the review of biomechanical testing performed on the Superion device. Results Results The effects of spinal position in extension and flexion have been shown to have an impact in the variation in dimensions of the spinal canal and foramina areas. Overall studies have shown that spinal positions from flexion to extension reduce the spinal canal and foramina dimensions and increase ligamentum flavum thickness. Biomechanical test data have shown that the Superion device resists extension and reduces angular movement at the implantation level and provides significant segmental stability. Conclusions Conclusions Superion interspinous lumbar decompression is a minimally invasive, low-risk procedure for the treatment of lumbar spinal stenosis, which has been shown to have a low safety profile by maintaining sagittal alignment, limiting the potential for device dislodgment or migration, and to preserve mobility and structural elements.","PeriodicalId":19909,"journal":{"name":"Pain Medicine: The Official Journal of the American Academy of Pain Medicine","volume":"21 1","pages":"S14 - S22"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87555649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
When planning a targeted interventional pain procedure involving the injection of corticosteroid combined with a local anesthetic, consideration should be given to the possible formation of large crystal precipitates. Any crystal larger than the diameter of an RBC (6–8 microns) could potentially obstruct arterioles, with ensuing occlusion and tissue ischemia. This is of particular concern when considering the implications of inadvertent arterial injection during TFESI or any other procedure performed in close proximity to the arterial supply of neural structures.
