OBJECTIVE To test the hypothesis that acupuncture improves symptoms of fibromyalgia. PATIENTS AND METHODS We conducted a prospective, partially blinded, controlled, randomized clinical trial of patients receiving true acupuncture compared with a control group of patients who received simulated acupuncture. All patients met American College of Rheumatology criteria for fibromyalgia and had tried conservative symptomatic treatments other than acupuncture. We measured symptoms with the Fibromyalgia Impact Questionnaire (FIQ) and the Multidimensional Pain Inventory at baseline, immediately after treatment, and at 1 month and 7 months after treatment. The trial was conducted from May 28, 2002, to August 18, 2003. RESULTS Fifty patients participated in the study: 25 in the acupuncture group and 25 in the control group. Total fibromyalgia symptoms, as measured by the FIQ, were significantly improved in the acupuncture group compared with the control group during the study period (P = .01). The largest difference in mean FIQ total scores was observed at 1 month (42.2 vs 34.8 in the control and acupuncture groups, respectively; P = .007). Fatigue and anxiety were the most significantly improved symptoms during the follow-up period. However, activity and physical function levels did not change. Acupuncture was well tolerated, with minimal adverse effects. CONCLUSION This study paradigm allows for controlled and blinded clinical trials of acupuncture. We found that acupuncture significantly improved symptoms of fibromyalgia. Symptomatic improvement was not restricted to pain relief and was most significant for fatigue and anxiety.

Background: How psychosocial factors may impact on weight loss after bariatric surgery is not well understood. This lack of knowledge is problematic, because there is a high prevalence of psychosocial distress in patients seeking treatment for obesity in hospital-based programs. The purpose of this study was to examine the relationship between preoperative psychosocial factors and eventual weight loss. Method: Between 1987 and 1998, all individuals undergoing Roux-en-Y gastric bypass for weight loss in our institution had psychologic preoperative evaluations. Patients who were followed prospectively were studied. The relation of having received mental health treatment to percentage of excess weight loss at 2 years is examined using t-tests. Results: 62 women and 18 men completed a 2-year follow-up. Patients who had received treatment for either substance abuse (n=10) or psychiatric co-morbidity (n=39) lost more weight compared with those without such histories (P<0.05, P <0.001 respectively). Conclusion: Given these results, it is plausible that a history of having received either psychiatric treatment for a disorder or counseling for substance abuse should not be a contraindication to bariatric surgery, and, in fact, may be prognostic of favorable outcome. Further research examining psychosocial factors and outcome from bariatric surgery is clearly warranted.

OBJECTIVE To study differences in treatment outcomes between patients with chronic noncancer pain taking vs those not taking maintenance opioids at admission to a pain rehabilitation program. PATIENTS AND METHODS A nonrandomized 2-group prepost design was used to compare 356 patients admitted to the Mayo Comprehensive Pain Rehabilitation Center from January 2002 to December 2002 at admission and discharge by opioid status at admission. Measures of pain severity, interference due to pain, perceived life control, affective distress, activity level, depression, and catastrophizing (an exaggerated negative mental set associated with actual or anticipated pain experiences) were used to compare opioid and nonopioid groups. The patients entered a 3-week intensive outpatient multidisciplinary pain rehabilitation program designed to improve adaptation to chronic noncancer pain. The program uses a cognitive-behavioral model and incorporates opioid withdrawal. RESULTS More than one third of patients (135/356) were taking opioids daily at admission. At completion of the program, all but 3 of the 135 patients had successfully discontinued opioid treatment. No significant pretreatment differences were found between the opioid and nonopioid group regarding demographics, pain duration, treatment completion, or all outcome variables, including pain severity. Significant improvement was noted at discharge for all outcome variables assessed regardless of opioid status at admission. CONCLUSION Patients with symptomatically severe and disabling pain while taking maintenance opioid therapy can experience significant improvement in physical and emotional functioning while participating in a pain rehabilitation program that incorporates opioid withdrawal.

Although abdominal pain is a symptom of several structural gastrointestinal disorders (eg, peptic ulcer disease), this comprehensive review will focus on the 4 most common nonstructural, or functional, disorders associated with abdominal pain: functional dyspepsia, constipation-predominant and diarrhea-predominant irritable bowel syndrome, and functional abdominal pain syndrome. Together, these conditions affect approximately 1 in 4 people in the United States. They are associated with comorbid conditions (eg, fibromyalgia and depression), impaired quality of life, and increased health care utilization. Symptoms are explained by disordered gastrointestinal motility and sensation, which are implicated in various peripheral (eg, postinfectious inflammation and luminal irritants) and/or central (eg, stress and anxiety) factors. These disorders are defined and can generally be diagnosed by symptoms alone. Often prompted by alarm features, selected testing is useful to exclude structural disease. Identifying the specific diagnosis (eg, differentiating between functional abdominal pain and irritable bowel syndrome) and establishing an effective patient-physician relationship are the cornerstones of therapy. Many patients with mild symptoms can be effectively managed with limited tests, sensible dietary modifications, and over-the-counter medications tailored to symptoms. If these measures are not sufficient, pharmacotherapy should be considered for bowel symptoms (constipation or diarrhea) and/or abdominal pain; opioids should not be used. Behavioral and psychological approaches (eg, cognitive behavioral therapy) can be helpful, particularly in patients with chronic abdominal pain who require a multidisciplinary pain management program without opioids.

OBJECTIVE The cost of caring for patients with chronic pain conditions poses a significant burden to both the healthcare system and patients. We were interested in analyzing the financial costs and benefits of treating these patients in a comprehensive outpatient pain rehabilitation program. DESIGN All participants completed the 3-week outpatient Mayo Clinic Florida Pain Rehabilitation Program (PRC) between October 2011 and September 2013. Healthcare costs were compared during the 3-, 6-, 12-, and 18-month periods pre- and post-treatment. PATIENTS The sample included 53 patients. RESULTS Medical costs decreased by 86, 68, 64, and 90% in the 3-, 6-, 12-, and 18-month post-treatment periods, respectively, when compared with the same pretreatment periods. CONCLUSIONS The appropriate use of a comprehensive outpatient rehabilitation program for chronic pain patients can result in a significant reduction in medical costs.

OBJECTIVES Investigate whether percutaneous spinal cord stimulator (SCS) leads migrate significantly during a 3-day trial, and determine whether the skin anchoring method influences lead migration. MATERIAL AND METHODS Twenty patients were prospectively enrolled. Ten leads were anchored with suture and tape and 10 were anchored with tape only. A standardized X-ray protocol of lead position was obtained immediately following lead placement and upon completion of the trial. RESULTS Using a standardized method, SCS leads were measured and movement was calculated. The average movement for leads anchored with tape only was 8.72 mm (SD=5.77), inferiorly; while movement for leads anchored with suture and tape was 24.49 mm (SD=11.3), inferiorly. A t-test revealed a significant difference between the groups (t=3.9, P=0.001). CONCLUSIONS Percutaneous SCS trial electrodes migrate significantly, inferiorly, during a 3-day trial. Anchoring the trial electrodes to the skin with a suture and tape results in significantly greater inferior migration when compared with anchoring the lead with tape only.

There have been several recent studies of the epidemiology and costs attributable to the chronic pain and chronic fatigue syndromes. Although investigations of the putative mechanisms of these disorders continue, there remains a poor understanding of their underlying pathophysiology. Four studies are reviewed that further support the commonality of both physical symptoms and psychological distress in chronic pain and chronic fatigue syndromes. By considering these commonalities, a comprehensive behavioral-rehabilitative approach can be undertaken to assist patients in addressing their adaptive difficulties. An overview of admission criteria for pain rehabilitation services is provided. Finally, recent empirical studies of both treatment process and outcome provide further support for the effectiveness and long-term benefits of this approach.

Objective. To examine the efficacy of interdisciplinary rehabilitation for improving function in people with chronic pain. Design. Retrospective Chart Review. Setting. The Pain Rehabilitation Center (PRC) at a medical center. Participants. Individuals admitted to the PRC. Interventions. The PRC operates a 3-week outpatient program that utilizes an interdisciplinary approach to treat people with chronic pain. The main treatment elements include physical therapy, occupational therapy, cognitive behavioral therapy (CBT), and medication management. Physical therapy groups focus on moderate exercise despite symptoms. Occupational therapists teach moderation, time management, and activity modification. CBT groups, led by a pain psychologist, address the psychosocial comorbidities of chronic pain. Medical staff oversee the tapering of opiate analgesics and other symptom targeted treatments. This integrated approach is indicated when conventional treatments have been ineffective. Outcome Measures. The objective outcome was the 6-minute walk test (6 mWT) distance. The subjective outcomes were performance (COPM-PER) and satisfaction (COPM-SAT) as measured by the Canadian Occupational Performance Measure (COPM). Results. Average 6 mWT distances improved by 39% from 375 m to 523 m. Average COPM-PER scores increased from 3.4 to 7.5. Average COPM-SAT scores increased from 2.4 to 7.5. Conclusions. Comprehensive interdisciplinary outpatient rehabilitation can significantly improve function in people with chronic pain.

Background The serotonin (5-HT) transporter-linked polymorphic region (5-HTTLPR) moderates the relationship between stressful life events and depression. Given the high prevalence of depression in chronic pain, the primary aim of this preliminary study was to investigate the associations between the 5-HTTLPR and the severity of depressive symptoms in a cohort of adults with chronic pain. Methods Adults with chronic pain who were consecutively admitted to an outpatient pain rehabilitation program and met inclusion criteria were recruited for study participation (n=277). Individuals were genotyped for the 5-HTTLPR (including rs25531) and categorized as high, intermediate, or low expressors of the 5-HT transporter. The severity of depressive symptoms at admission was measured by using the Center for Epidemiologic Depression scale (CES-D). Results The distribution of the high-, intermediate-, and low-expressing genotypes was 61 (22%), 149 (54%), and 67 (24%), respectively. The Hardy–Weinberg P-value was 0.204, which indicated no departure from equilibrium. A main effect of 5-HTTLPR was observed for depressive symptoms (P=0.040) where Center for Epidemiologic Depression scale (CES-D) scores were significantly greater in the low-expressing group compared to the high- (P=0.019) and intermediate (P=0.029)-expressing groups. In multivariate multinomial logistic regression analysis adjusted for age, sex, pain severity, pain catastrophizing, and pain anxiety, greater CES-D scores were significantly associated with the 5-HTTLPR low-expressing group compared to the high-expressing group (P=0.023), but not for the low-expressing group compared to the intermediate-expressing group (P=0.056). Conclusion These preliminary findings suggest that the triallelic 5-HTTLPR could influence the severity of depressive symptoms in adults with chronic pain. Individuals with chronic pain may be particularly vulnerable to the moderating effects of 5-HTTLPR due to high levels of pain-related stress that are inherently present in this population.

Introduction Post-laminectomy syndrome (PLS) patients who have previously undergone spinal cord stimulation and failed to have significant improvement create a unique challenge for ongoing pain management. We hypothesize that, following successful completion of intensive, interdisciplinary pain rehabilitation (IPR), this patient population can achieve a significant reduction in pain, improvement in mood, functional levels, and self-efficacy. Materials and methods A retrospective chart review was conducted comparing the following for patients prior to enrollment in the IPR program and upon completion: numeric rating scale (NRS) pain scores; functional status via the six-minute walk test; mood via the Center for Epidemiologic Studies Depression Scale (CES-D), Multidimensional Pain Inventory (MPI) Life control scores and MPI Interference, and the Pain Catastrophizing Scale (PCS); and self-efficacy via the Pain Self-Efficacy Questionnaire (PSEQ). Results Forty-three patients met inclusion criteria, with 17 males and 26 females and a mean age of 64 years. Patients demonstrated a statistically significant increase in six-minute walk test distance of 104 m, a decrease in average NRS pain score of 1.4 points, an increase in average MPI life control by 8.3 points, a decrease average MPI interference by 5.3 points, an increase in average Short Form-36 by 6.5 points, an increase in average PCS by 4.4 points, and an increase in average PSEQ score of 18.1. Their average mood via CES-D improved by 4.2 points. Conclusions Intensive, interdisciplinary pain rehabilitation provides an effective therapeutic modality for patients with post-laminectomy syndrome who have failed spinal cord stimulation by decreasing pain levels and by increasing functional status and self-efficacy.
