Dr Martin Hirsch Clinical Research Fellow Women’s Health Research Unit Queen Mary University of LondoMedicalResearch.com Interview with: Dr Martin Hirsch Clinical Research Fellow Women’s Health Research Unit Queen Mary University of London and Dr Jenny Hole Foundation Year 1 Doctor Kettering University Hospital Dr Jenny Hole Foundation Year 1 Doctor Kettering University Hospital   MedicalResearch: What is the background for this study? What are the main findings? Response: As doctors we see medicines being prescribed on a daily basis and the benefit but also harm that they can cause. We wanted to assess the role of non pharmaceutical interventions which can benefit patients with a low or minimal potential for harm. We all have an interest in music of different genres and we agreed that we didn’t know anybody who did not like music of one sort or another. On the basis that we all have gained pleasure from music, we wanted to see if this pleasurable experience at the time of a difficult and painful stimulus could reduce the problems encountered as people recover from surgery. We searched all published medical literature and found 73 of the highest quality studies (randomised controlled trials) to compare and combine their findings in a meta-analysis. This technique aims to strengthen the validity by producing a combined result. We found that using music before during or after surgery reduced pain, reduced the requirement for pain killers, reduced anxiety, and improved satisfaction. (more…)

Richard L. Nahin, Ph.D., M.P.H National Center for Complementary and Integrative Health National Institutes of Health, Bethesda, MarylandMedicalResearch.com Interview with: Richard L. Nahin, Ph.D., M.P.H National Center for Complementary and Integrative Health National Institutes of Health, Bethesda, Maryland Medical Research: What is the background for this study? Dr. Nahin: In 2011 the Institute of Medicine published a blueprint for transforming pain care in the United States.  In this report the IOM noted the lack of a comprehensive picture of pain’s prevalence and severity in the U.S., and especially noted that lack of data examining racial and ethnic groups. The current analysis of data from the 2012 National Health Interview survey is a step toward addressing these deficiencies.  Medical Research: What are the main findings? Dr. Nahin: The analyses found that an estimated 25.3 million adults (11.2 percent) had pain every day for the preceding 3 months. Nearly 40 million adults (17.6 percent) experience severe levels of pain.  Those with severe pain are also likely to have worse health status.  There were associations between pain severity and race, ethnicity, language preference, gender, and age. Women, older individuals, and non-Hispanics were more likely to report any pain, while Asians were less likely.  Minorities who did not choose to be interviewed in English are markedly less likely to report pain.

Edward W. Cowen, MD, MHSc Dermatology Branch, Center for Cancer Research National Cancer Institute Bethesda, MarylandMedicalResearch.com Interview with: Edward W. Cowen, MD, MHSc Dermatology Branch, Center for Cancer Research National Cancer Institute Bethesda, Maryland Medical Research: What is the background for this study? Dr. Cowen: Cutaneous leiomyomas are benign smooth muscle proliferations that are associated with pain that is typically not well-controlled by topical remedies or systemic pain medication. Hereditary leiomyomatosis and renal cell cancer is a rare syndrome in which patients may have dozens or even hundreds of these painful tumors. We sought to determine if botulinum toxin injected directly into leiomyomas may ameliorate discomfort and improve quality of life in patients who experience significant pain from cutaneous leiomyomas. Medical Research: What are the main findings? Dr. Cowen: In a double-blinded placebo-controlled study, we found that injection of botulinum toxin was associated with improved skin-related quality of life (p = 0.007) and decreased skin-specific pain (p = 0.048) on the Dermatology Life Quality Index. A trend for decreased pain (p = 0.06) by visual analog score was reported in the botulinum toxin treated group compared to the placebo group. (more…)

Dr. Bannuru: Placebos are used to determine the efficacy of a wide variety of treatments for medical conditions such as osteoarthritis. A sound understanding of potential differences among placebos is essential for determining the relative efficacy of such treatments. Medical Research: What are the main findings? Dr. Bannuru: Our results indicate that different types of placebos do in fact differ in efficacy. Placebo injections and topical placebos were both found to be more effective than orally administered placebos for reducing knee osteoarthritis pain. (more…)

Mark S. Wallace MD Department of Anesthesiology School of Medicine University of California, San Diego, CaliforniaMedicalResearch.com Interview with: Mark S. Wallace MD Department of Anesthesiology School of Medicine University of California, San Diego, California Medical Research: What is the background for this study? What are the main findings? Dr. Wallace: The study was funded by the center for medicinal cannabis research at the University of California San Diego. The center was funded by the state of California. The center was the first to fund a series of double-blind randomized controlled trials with inhaled cannabis for neuropathic pain. My trial is the first in diabetic peripheral neuropathy pain which is one of the most prevalent pain syndromes in our society with limited treatments. We found a dose dependent reduction in pain. However there was also a dose dependent increase in euphoria and sedation which may limit clinical use. Effects on neurocognitive functioning were minimal. (more…)

MedicalResearch.com Interview with: Prof. Jason Smith Consultant in Emergency Medicine, Derriford Hospital, Plymouth, UK Royal College of Emergency Medicine Professor Defence Professor of Emergency Medicine, Academic Department of Military Emergency Medicine, Royal Centre for Defence Medicine, UK Honorary Professor in Emergency Medicine, Plymouth University Peninsula Schools of Medicine and Dentistry, UK Medical Research: What is the background for this study? Prof. Smith: Patients commonly present to emergency departments in pain. When patients are asked about their emergency department experience, they often say that more could have been done to manage their pain. Routine care for patients in moderate or severe pain who present to emergency departments usually involves intravenous (IV) morphine, delivered by a nurse. There may be a delay when patients are admitted to a hospital ward before they are reviewed by the admitting medical team, when their pain needs are reassessed. Patient controlled analgesia (PCA) is used to good effect elsewhere in the hospital. The aim of this study was to compare PCA with routine care in patients presenting to emergency departments with either traumatic injuries or non-traumatic abdominal pain, who require admission to hospital. Medical Research: What are the main findings? Prof. Smith: We found that significant reductions in pain were possible using patient controlled analgesia in patients with abdominal pain. Patients spent significantly less time in moderate or severe pain, and were more likely to be very or perfectly satisfied with their pain management. In patients with traumatic injuries, a modest (but non-significant) reduction in pain was seen in patients allocated to the PCA group compared with the routine care group. Patients in the PCA group were more likely to be very or perfectly satisfied with their pain management. (more…)

Dr. Mia T. Minen, MD, MPH Director, Headache Services at NYU Langone Medical Center Assistant professor, Department of Neurology MedicalResearch.com Interview with: Dr. Mia T. Minen, MD, MPH Director, Headache Services NYU Langone Medical Center Assistant professor, Department of Neurology   Medical Research: What is the background for this study? What are the main findings? Dr. Minen: We conducted a survey on opioid and barbiturate use among patients visiting a headache center to find out which medications they were receiving for treatment. There’s limited evidence that long-term use of these medications can help treat headaches or migraines, and even short-term use in small quantities can cause medication overuse headache. It is important to determine which providers start these medications so that educational interventions can be tailored to these physician specialties to try to prevent situations such as incorrect prescribing practices and medication overuse. In this sample of patients from a specialty headache center, approximately 20 percent of patients -- or 1 in 5 -- were using opioids or barbiturates, and about half had been prescribed these medications at some point in the past for their headaches. These findings show that opioids and barbiturates are commonly prescribed to patients with headaches. While two-thirds of patients found opioids or barbiturates helpful, many did not like them, were limited by side effects or did not find them to be helpful. Emergency department physicians were reported to be the most frequent first prescribers of opioids and general neurologists were the most frequent prescribers of barbiturate-containing medications. Primary care physicians were also identified as frequent first prescribers of these medications. (more…)

Harley Goldberg, DO Physical Medicine and Rehabilitation Kaiser PermanenteMedicalResearch.com Interview with: Harley Goldberg, DO Physical Medicine and Rehabilitation Kaiser Permanente Medical Research: What is the background for this study? What are the main findings? Dr. Goldberg: This is the first large-scale randomized, double-blind, placebo-controlled clinical trial of oral steroids for acute radiculopathy, commonly called sciatica, associated with a herniated lumbar disk. Lumbar radiculopathy (or pain down the leg in a lumbar nerve root distribution) is a common source of pain and disability for many adults. It is thought that inflammation from a disk herniation is responsible for many of the symptoms, so giving a powerful anti-inflammatory, such as steroid medication, might help relieve sciatica symptoms quickly. Prior research has shown that lumbar diskectomy does not affect the one year outcome for most patients, and epidural steroid injections do not have strong support by clinical trials. If the use of epidural steroids injections is based on application of steroid anti-inflammatory to the affected nerve root(s), perhaps an oral steroid can have affect. Although oral steroids are used by many physicians and have been included in some clinical guidelines, no large-scale clinical trials of oral steroids for sciatica have been conducted before. Our study found that among patients with acute radiculopathy associated with a herniated lumbar disk, a short course of oral steroids resulted in only modest improvement in function and no significant improvement in pain.

MedicalResearch.com Interview with: Winfried Meissner, M.D. Dep. of Anesthesiology and Intensive Care Jena University Hospital University Hospital Jena, Germany Medical Research: What is the background for this study? Dr. Meissner: Post-operative pain is managed inadequately worldwide. There are probably many reasons for this, one of which may be lack of evidence about outcomes of treatment in the clinical routine. PAIN OUT was established  as a  multi-national research network and quality improvement project offering healthcare providers  validated tools to collect data about pain-related patient reported outcomes and management after surgery. Patients fill in a questionnaire asking for pain intensity, pain interference and side effects of pain management. The questionnaire has now been translated into 20 languages. Data are collected electronically and clinicians are provided with feedback about management of their own patients, compared to similar patients in other hospitals.  Furthermore, the findings are used for outcomes and comparative effectiveness research. PAIN OUT is unique in that  outcomes of postoperative pain management can be examined internationally. PAIN OUT was created in 2009 with funds from the European Commission, within the FP7 framework and  has now been implemented in hospitals in Europe, USA, Africa and SE Asia. The findings allow us to gain insights as to how pain in managed in different settings and countries. For this particular study, we compared management of pain in the US to other countries. We assessed a large group of patients who underwent different types of orthopedic surgery and compared their patient reported outcomes and management regimens. We included 1011 patients from 4 hospitals in the USA  and 28,510 patients from  45  hospitals in 14 countries (“INTERNATIONAL”). Medical Research: What are the main findings? Dr. Meissner: Postoperative pain intensity of US patients was higher than in INTERNATIONAL patients; they felt more often negatively affected by pain-associated anxiety and helplessness, and more US patients stated they wished to have received more pain treatment. However, other patient-reported outcomes like time in severe pain or the level of pain relief did not differ. We found that treatment regiments of American patients differed compared to INTERNATIONAL patients. More US patients received opioids, and their opioid doses were higher compared to INTERNATIONAL patients. In contrast, INTERNATIONAL countries use more nonopioid medications intraoperatively and postoperatively. Thus, under-supply with opioids cannot explain our findings. Mean BMI of US patients was 30.3 while for INTERNATIONAL it was 27.4. However, insufficient evidence exists that this finding might account for differences in pain intensity. Routine pain assessment was performed in almost all US patients, in contrast to about 75% in the INTERNATIONAL group. Obviously, routine pain assessment, as practiced in the United States, fails to result in lower postoperative pain. Perhaps it has the opposite effect by directing patients’ attention to the pain.

Hassan R. Mir, MD, MBA Associate professor of Orthopaedics and Rehabilitation Vanderbilt Orthopaedic InstituteMedicalResearch.com Interview with: Hassan R. Mir, MD, MBA Associate professor of Orthopaedics and Rehabilitation Vanderbilt Orthopaedic Institute and and Brent J. Morris, M.D. Shoulder and Elbow Surgery Fellowship Texas Orthopaedic Hospital in affiliation with the University of Texas Houston Health Science Center, Houston, TexasDr. Brent J. Morris, M.D. Shoulder and Elbow Surgery Fellowship Texas Orthopaedic Hospital University of Texas Houston Health Science Center, Houston, Texas Medical Research: What is the background for this study? What are the main findings? Dr. Mir: The past few decades have seen an alarming rise in opioid use in the United States, and the negative consequences are dramatically increasing. The US represents less than 5% of the world's population, yet consumes 80% of the global opioid supply. Management of pain is an important part of patient care, however, the increased usage of opioids for the treatment of pain has led to several unanticipated aftereffects for individual patients and for society at large. Orthopaedic surgeons are the third highest prescribers of opioid prescriptions among physicians in the United States. Orthopaedic patients can experience a tremendous amount of pain with acute injuries and chronic conditions, and the treatment plan may involve opioid prescriptions for relief of discomfort. A significant number of orthopaedic patients and their families are at risk for repercussions from opioid use. We must work together to decrease the use of opioids for musculoskeletal pain. Clinicians should aim to control pain and improve patient satisfaction while avoiding overprescribing opioids. A comprehensive strategy of risk assessment is needed to identify patients who may be at risk for opioid abuse. Objective measures including patient history, recognition of aberrant behavior, urine drug testing, state prescription drug–monitoring programs, and opioid risk-assessment screening tools may be necessary in select cases.

Author Interviews, Pain Research / 16.04.2015

MedicalResearch.com Interview with: Geoff Durso PhD Candidate Department of Psychology The Ohio State University Medical Research: What is the background for this study? What are the main findings? Response: Recent research has shown that acetaminophen blunts negative emotions beyond those arising from physical pain (e.g., social rejection). We hypothesized that this was the case because acetaminophen was having a broader effect on individuals' evaluative and emotional processing, given past psychological theory (e.g., differential susceptibility, personality differences in emotionality, etc) and related neurological evidence (acetaminophen affects serotonin neurotransmission in the brain, reduces inflammatory signaling in the brain, and decreases activation in the brain areas responsible for emotion, for instance--any one or combination of these effects could be responsible for the psychological outcomes that we observe on individuals' blunted negative and positive evaluations). So we conducted two double-blind studies (neither participants nor experiments were aware of participants' assignment to condition). What we found was that participants taking an acute dose of acetaminophen (compared to those taking an inert placebo control) reported diminished negative evaluations of displeasing stimuli (photographs of starving children, wartorn city blocks, disgusting toilets) as well as diminished positive evaluations of pleasing stimuli (photographs of children playing with kittens, a large pile of money, a couple in bed together). Participants taking acetaminophen also reported experiencing diminished emotional responses to the photographs overall. These findings supported our predictions that acetaminophen works to reduce pain in part because it has a broader blunting effect on individuals' evaluations and emotional experience. (more…)

Gustavo C Machado, PhD student The George Institute for Global Health, Sydney Medical School University of Sydney Sydney AustraliaMedicalResearch.com Interview with: Gustavo C Machado, PhD student The George Institute for Global Health, Sydney Medical School University of Sydney Sydney Australia (Editor’s note: Paracetamol isalso known as acetaminophen) MedicalResearch: What is the background for this study? What are the main findings? Response: Back pain and osteoarthritis are the two major musculoskeletal conditions affecting people worldwide, and paracetamol is the most used over the counter medicine to treat these conditions. Recent debates on the efficacy and safety of paracetamol prompted us to conduct a systematic review of literature on the efficacy of this medication. In our study we included all available clinical trials that compared paracetamol to placebo, and our conclusions are based on data from more than 5,300 patients with low back pain and hip or knee osteoarthritis. We found that paracetamol is ineffective for low back pain and provides small and not clinically important benefits to patients with osteoarthritis. (more…)

Jarvik MD MPH Professor, Radiology, Neurological Surgery and Health Services Adjunct Professor, Pharmacy and Orthopedics & Sports Medicine Director, Comparative Effectiveness, Cost and Outcomes Research Center University of Washington Seattle, WA 98104-2499MedicalResearch.com Interview with: Jeffrey (Jerry) G. Jarvik MD MPH Professor, Radiology, Neurological Surgery and Health Services Adjunct Professor, Pharmacy and Orthopedics & Sports Medicine Director, Comparative Effectiveness, Cost and Outcomes Research Center University of Washington Seattle, WA Medical Research: What is the background for this study? Dr. Jarvik:  When I arrived at the Univ of WA over 20 years ago, my mentor, Rick Deyo, had just finished leading a project that was responsible for developing one of the first set of guidelines for the diagnosis and treatment of acute low back pain. These guidelines, published in a booklet by AHRQ (then called AHCPR), recommended that patients with acute low back pain not undergo imaging for 4-6 weeks unless a red flag was present. One of the exceptions was that patients older than 50 could get imaged immediately, the rationale being that older adults had a higher prevalence of potentially serious conditions such as cancer, infections, etc, that would justify the early imaging. As a practicing neuroradiologist, it was clear that a potential problem with this strategy is that the prevalence of age-related changes, which may or may not be related to back pain, also increases with age. So earlier imaging of older adults would almost certainly reveal findings, and these could easily start a series of unfortunate events leading to potentially poor outcomes and more healthcare resource use. Thus this policy of early imaging of older adults didn’t entirely make sense. About 5 years ago, these guidelines hit home when I developed acute low back pain and since I was over 50 (barely) my doctor recommended that I get an imaging study. Being a knowledgeable patient and having a reasonable doctor, we mutually agreed not to get the study. I improved but that wasn’t the end of it. When we had the chance to apply for one of the CHOICE ARRA awards funded by AHRQ, we made answering this question of early imaging in older adults one of our primary goals. (more…)

Dr. Ferreira: Our study was set up to look at the common triggers for sudden and moderate to severe episodes of back pain. It included 1,000 participants with this condition. Participants were interviewed in the first week their pain episode occurred in and were asked to describe their physical and psychosocial activities in the 3 days preceding pain onset. MedicalResearch: What are the main findings? Dr. Ferreira: The results of the study have shown that sudden attacks of back pain are more likely to be triggered in the morning, between 8 am and 11 am. Being distracted while engaged in manual tasks, manual tasks performed in an awkward posture, or those involving objects not close to the body and lifting heavy loads were activities that most likely would trigger a new episode of back pain, even following very brief exposure (i.e. less than 2 hours). If you feel like this is you, you should visit a round rock chiropracter to aid progress! (more…)

MedicalResearch.com Interview with: Erin R. Schlemmer, MPH Health Care Manager / Epidemiologist Department of Clinical Epidemiology & Biostatistics Blue Cross Blue Shield of Michigan MedicalResearch: What is the background for this study? Response: Low back pain (LBP) is a common reason for emergency department (ED) visits. Usually, uncomplicated acute LBP is a benign, self-limited condition that can be managed without the need for imaging studies. However, national data have shown that a substantial proportion of ED patients with LBP receive imaging studies, and that the use of advanced imaging has increased considerably for this population in recent years. A number of groups (including specialty societies, a consortium of health plan medical directors, and an expert panel of emergency medicine physicians) have offered recommendations for the appropriate use of imaging for Low back pain. Within these guidelines, there are a number of “red flag” conditions that serve as indications for Low back pain imaging, and it is generally accepted that most patients do not require imaging to inform treatment of their Low back pain unless they have one or more red flags. Our objective was to use claims data from a large commercial insurer to describe the imaging indications and imaging status of patients presenting to the ED with Low back pain, and to describe demographic and healthcare use characteristics associated with non-indicated imaging. MedicalResearch: What are the main findings? Response: We found that over half (51.9%) of all patients presenting to the ED with low back pain had no claims-based evidence of indications for imaging. Overall, 36.5% of patients received imaging, and 10.2% received advanced imaging (CT or MRI). Among patients with imaging indications, the most common indication was trauma (71.6%), followed by cancer (24.0%). Although nearly a third of non-indicated patients received imaging, this population had a lower prevalence of imaging compared to patients with imaging indications (30.1% vs. 43.5%), and were also less likely to have prior healthcare use (such as ED visits) in the past year. Among non-indicated patients who received imaging, 26.2% received advanced imaging (CT or MRI) and 4.3% had >1 type of imaging. (more…)

Mafi, M.D. Fellow, Harvard Combined Program in General Medicine Beth Israel Deaconess Medical Center Brookline, MA 02446 MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Mafi: Headache costs our healthcare system over 30 billion dollars annually. Clinical guidelines recommend conservative treatments for uncomplicated headache, such as counseling on dietary trigger avoidance. The Choosing Wisely Campaign of the American Board of Internal Medicine has in turn identified advanced imaging (e.g. CT or MRI) and opioid or barbiturate medications as low value treatments in the management of headache. In this context we used a nationally representative database to evaluate trends in physician practice patterns on headache management. We found a doubling in use of advanced imaging, referrals to other physicians and no change in opioid/barbiturate medications, although these continued to be used at high rates (18%). We also found a decline in life-style modification counseling, meant to prevent headaches from starting. (more…)

Sandra Goldsmith, MA, MS, RD Director of Public and Patient Education at Hospital for Special Surgery New York City.MedicalResearch.com Interview with: Sandra Goldsmith, MA, MS, RD Director of Public and Patient Education at Hospital for Special Surgery New York City. Medical Research: What is the background for this study? What are the main findings? Response: Almost 50 million adults in the United States suffer from some form of musculoskeletal disorder, which can affect their mobility and quality of life. Osteoarthritis (OA) is the leading cause of disability in the U.S. and affects more than 70 percent of adults between the ages of 55 and 78. Research has shown that there is a connection between being physically active and maintaining joint health, pain relief and improved quality of life. This study attempts to support the efficacy of Hospital for Special Surgery’s hospital-based exercise programs in increasing physical activity and improving quality of life through pain relief and improved stiffness, fatigue and balance in the older adult community. This study found that after taking the exercise classes, fewer participants reported experiencing a high level of muscle/joint pain from their condition (56 percent before the program started vs. 47 percent after completing the program). The study also reported improved quality of life, as evidenced by statistically significant reductions in how much their pain interfered with their general activities, ability to walk, mood, sleep and enjoyment of life. In addition, 83 percent of participants indicated a reduction in stiffness; 82 percent said they felt their balance improved; and 67 percent said they experienced less fatigue as a result of taking part in the program. Health outcomes were also related to the type of exercise class participants chose, with the greatest reduction in muscle/joint pain reported by those who took t’ai chi. (more…)

MedicalResearch.com Interview with: Melissa Garrido, PhD Research Health Science Specialist GRECC, James J Peters VA Medical Center, Bronx, NY Assistant Professor Brookdale Department of Geriatrics & Palliative Medicine Icahn School of Medicine at Mount Sinai, New York, NY and Holly G. Prigerson, PhD Center for Research on End of Life Care Weill Cornell Medical College New York, NY 10065 Medical Research: What is the background for this study? What are the main findings? Response: Recent proposals in Congress encourage patients to engage in advance care planning and to complete advance directives. That is, patients are encouraged to have conversations about end-of-life care preferences and to document these preferences in writing (through living wills or medical orders such as do not resuscitate (DNR) orders) or to designate a durable power of attorney who can honor their preferences. The goal of advance care planning is to ensure that seriously ill patients receive care that matches their values. In this study, we used data from a prospective study of patients with advanced cancer and their caregivers to examine whether living wills, durable powers of attorney, and DNR orders were associated with better quality of life and lower estimated costs of care in the week before death. We examined these relationships among patients who did and did not express preferences for “heroic” end-of-life care (everything possible to remain alive). Medical Research: What are the main findings? Response: DNR orders were associated with better quality of life in the week before death among the entire sample. If patients have DNR orders completed, they are likely to have a better quality of life/quality of death than if they do not complete a medical order like this. We did not find any evidence of a relationship between DNR orders and costs of care, nor did we find evidence of relationships among living wills or durable powers of attorney, quality of life, and costs of care. There was no evidence that relationships among advance care planning and outcomes differed by patient preferences for heroic care. (more…)

Fellow / Læge, Ph.d. studerende Department of Surgery Herlev Hospital Gastroenheden, Herlev Hospital Medical Research: What is the background for this study? Dr. Andersen: The sleep hormone, melatonin is diverse molecule. Several experimental animal studies have documented significant antinociceptive effects in a wide range of pain models. In perioperative medicine, administration of melatonin has demonstrated anxiolytic, analgesic and anti-oxidant effects. Optimization of the analgesic treatment in surgical patients is required due to documented inadequate analgesia and the risk of adverse effects and complications caused by commonly used NSAIDs and opioids. Our goal was to investigate if melatonin was able to reduce pain scores or analgesic use in patients undergoing laparoscopic cholecystectomy. (more…)

Dr. Metcalf: This study investigated whether acupuncture is an effective treatment for people aged more than 50 years with chronic knee pain. Participants in our study were randomly assigned to one of four groups; needle acupuncture, laser acupuncture, sham laser acupuncture or no treatment. The people in the treatment groups received acupuncture treatment from a family physician for 12 weeks. Participants were assessed after treatment and again after one year. There were no significant differences in knee pain or physical function between active and sham laser acupuncture at 12 weeks or at one year. Both needle and laser acupuncture resulted in modest improvements in pain compared with no treatment at 12 weeks that were not maintained at one year. Needle acupuncture improved physical function at 12 weeks compared with no treatment but was not different from sham acupuncture and was not maintained at one year. (more…)

Gert Bronfort, DC, PhD Professor, Integrative Health and Wellbeing Research Program Center for Spirituality & Healing University of MinnesotaMedicalResearch.com Interview with: Gert Bronfort, DC, PhD Professor, Integrative Health and Wellbeing Research Program Center for Spirituality & Healing University of Minnesota Medical Research: What are the main findings of the study? Were any of the findings unexpected? Dr. Bronfort: Our study found that spinal manipulative therapy  SMT coupled with home exercise and advice (HEA) appears to be helpful compared to home exercise and advice alone (especially in the short term) for patients with sub-acute and chronic back-related leg pain (BRLP). BRLP was defined as radiating pain originating from the lumbar spine, which travels into the proximal or distal lower extremity, with or without neurological signs. Patients with progressive neurological deficits, cauda equina syndrome, spinal fracture, and other potentially serious causes of BRLP (and often candidates for surgery) were EXCLUDED. There were a few things we did find to be quite interesting. First, it is notable that the spinal manipulative therapy & home exercise and advice group experienced less self-reported medication use after one year than the  home exercise and advice alone group (SMT&HEA was 2.6 times more likely to experience fewer medication days than HEA alone at 1 year). Given the growing concerns of overuse of pain medications (and the potential for adverse events and addiction), this is a finding that has important public health consequence. Another interesting and important finding is that the adverse events observed in this study were only mild to moderate and self-limiting. No serious adverse events occurred that were related to the study interventions. Mild to moderate adverse events (e.g. temporary aggravation of pain, muscle soreness, etc.) were reported by 30% of the patients in the SMT&HEA group, and 42% in the HEA group. This is important as few studies have systematically recorded the side effects and adverse events related to SMT&HEA and HEA alone; this is one of the first, larger clinical trials to do so. These findings are especially notable because SMT is often not recommended for patients with leg symptoms because of safety concerns (which might be related to the previous absence of robust scientific data to support its use). Finally, while an advantage of SMT& HEA versus HEA was found (especially in the short term), we do find the findings of the HEA alone group to also be of interest. Almost half of the HEA patients experienced a 50% reduction in leg pain symptoms in both the short (at 12 weeks) and long term (at 52 weeks). That’s an important improvement and warrants future investigation. Self-management strategies (like home exercise) that emphasize the importance of movement and fitness, restoration of normal activities, and allow patients to care for themselves embrace important principles for promoting overall health and wellbeing that could have a big impact if routinely put into practice.

MedicalResearch.com Interview with: Natalie Sidorkewicz, MSc (Kin) PhD (HSG) Student Spine Biomechanics Laboratory School of Public Health and Health Systems, Faculty of Applied Health Sciences University of Waterloo Waterloo, ON Medical Research: What are the main findings of the study? Answer: First, we successfully documented male spine motion and muscle activity during sex -- this biomechanics study was the first of its kind. Second, we used this data to develop general recommendations for low back pain patients whose pain is worsened by motions and postures. The general recommendations focus on changing how people move, and position themselves during sex, as seen on websites similar to Nu-Bay. To make any sex position more spine-sparing, we recommend that the individual controlling the movement use their hips and knees more than their spine and that the individual not controlling the movement maintain a more neutral-spine position. An excellent working example is one of the sex positions that we studied: the missionary position. The man, who is controlling the movement with pelvic thrusting, is recommended to do so with more hip and knee movement than spine movement. The women, who is lying on her back, is recommended to use a back support placed underneath the natural curve of her spine to maintain a more neutral spine position. The general recommendations can be applied to any sex position for both men and women. Finally, we developed specific guidelines for men whose back pain is worsened by two specific types of motion: flexion and extension. If a man's low back pain is worsened by spine flexion movements, such as touching their toes or sitting for long periods of time, we would consider them to be flexion-motion-intolerant. The ideal sex position for a flexion-motion-intolerant patient would then be one that uses minimal spine flexion, so as not to worsen that patient's pain. When we compared the five sex positions, which you can do yourself by checking out some videos on a website such as sex free hd xxx, we found that men used the least amount of spine flexion in doggy-style as well as the missionary position as long as the male was propped up on his hands (as opposed to his elbows). If a man's low back pain is worsened by spine extension movements, such as arching their back or lying on their stomach, we would consider them to be extension-motion-intolerant. The ideal sex position for an extension-motion-intolerant patient would then be one that uses minimal spine extension, so as not to worsen the patient's pain. When we compared the five sex positions, we found that men used the least amount of spine extension in spooning and the missionary position as long as the male was propped up on his elbows (as opposed to his hands).

Ian Gilron, MD, MSc, FRCPC Director of Clinical Pain Research Professor of Anesthesiology & Perioperative Medicine, Biomedical & Molecular Sciences, and Center for Neuroscience Studies Queen's University Kingston General Hospital, Kingston, Ontario, CanadaMedicalResearch.com Interview with: Ian Gilron, MD, MSc, FRCPC Director of Clinical Pain Research Professor of Anesthesiology & Perioperative Medicine, Biomedical & Molecular Sciences, and Center for Neuroscience Studies Queen's University Kingston General Hospital, Kingston, Ontario, Canada Medical Research: What are the main findings of the study? Dr. Gilron: Pain is the most common symptom which prevents recovery from surgery. Even with the best available treatments today, many patients still suffer from moderate to severe pain after surgery. Antidepressants - drugs used to treat depression - are also proven effective for treating chronic pain due to nerve disease and fibromyalgia. However, there has been much less research on the effects of antidepressant drugs on pain after surgery. Our group conducted a systematic review of all published clinical trials of antidepressant for post surgical pain. Slightly more than half of these studies suggested some benefit of these drugs but the details of this review led us to conclude that there is not yet enough evidence to recommend these medications for post surgical pain treatment. Given the possibility that these medications could be useful treatments for pain after surgery, we believe that future studies of higher scientific quality and which involve larger numbers of patients should be carried out in the hopes of finding safer and more effective treatments for pain after surgery.
