Use of complementary and alternative therapies by patients with self-reported chronic back pain: a nationwide survey in Canada

Low back pain patients' perceived effectiveness of utilizing complementary and alternative medicine: a systematic review of qualitative studies

OBJECTIVES

The purpose of this systematic review of qualitative studies is to explore patients' perceived effectiveness of utilizing complementary and alternative medicine (CAM) for the treatment and/or management of low back pain (LBP).

METHODS

MEDLINE, EMBASE, AMED, and CINAHL were systematically searched from database inception until May 2020. Eligible articles included qualitative data about LBP patients' perceptions of using CAM.

RESULTS

Of 1,567 items, 1,542 items were excluded; the remaining 25 articles were included in this review. Three themes emerged as follows: physical benefits; mental health benefits; and negative or no perceived effectiveness of CAM on patients with LBP.

CONCLUSIONS

This study explores perceptions of CAM effectiveness among patients with LBP. These findings provide valuable information to CAM and non-CAM practitioners regarding the importance of individualized patient care based on their preferences, values, needs, and perspectives. Further exploration could include practitioners' perceptions of CAM and their impact on the patient-practitioner relationship.

A taxonomy of risk-associated alternative health practices: A Delphi study

Defining alternative health care and the recording of associated adverse events and harm remains problematic. This Canadian study aimed to establish and classify risk-associated alternative health practices in a Delphi study undertaken with an interdisciplinary panel of 17 health experts in 2020. It provides a new functional definition of alternative health care and an initial taxonomy of risk-associated alternative health care practices. A number of risk-associated practices were identified and categorized into general practices that conflict with biomedical care or largely untested therapies, alternative beliefs systems, physical manipulative alternative therapies, and herbal and nutritional supplements. Some risk significant harms including major physical injuries or even death. The lack of systematic methods for recording adverse events in alternative health care makes establishing the frequency of such events challenging. However, it is important that people engaging with alternative health care understand they are not necessarily risk-free endeavours, and what those risks are.

A Questionnaire Study on the Use of Complementary and Alternative Veterinary Medicine for Horses in Sweden

Complementary or alternative veterinary medicine (CAVM) includes treatment methods with limited scientific evidence. Swedish veterinarians are legally obliged to base treatments and recommendations on science or well-documented experience, but most CAVM methods are not well documented in animals. The aim of this study was to explore the use of CAVM in Swedish horses. Electronic questionnaires were distributed to horse owners, equine veterinary practitioners and CAVM therapists. Of the 204 responding horse owners, 83% contacted a veterinarian first in case of lameness, while 15% contacted a CAVM therapist. For back pain, 52% stated a CAVM therapist as their first contact and 45% a veterinarian. Only 10-15% of the respondents did not use any CAVM method for prevention or after injury. Of the 100 veterinarians who responded, more than half did not use CAVM themselves but 55% did refer to people who offer this service. Of the 124 responding CAVM therapists, 72% recommended their clients to seek veterinary advice when needed, 50% received referrals from a veterinarian, and 25% did not collaborate with a veterinarian. The two most common methods used by the respondents in all three categories were stretching and massage. Most veterinarians and therapists were not content with the current lack of CAVM regulation.

Complementary and Alternative (CAM) Treatment Options for Women with Pelvic pain

Purpose of review

I.To provide an overview of the current complementary and alternative (CAM) treatment options for women with chronic pelvic pain (CPP).

Recent findings

II.Recent studies on chronic pain at cellular, molecular and network level and their interaction with the immune system has unfolded several mechanisms for pain making it promising to explore the alternative paradigm to manage the incredibly complex chronic pelvic pain condition where multifactorial etiology often limits successful outcomes.

Summary

III.The multifactorial nature and complexity in establishing the underlying diagnosis in CPP limits predictable response to traditional medical and interventional options. Complementary and alternative options have been studied to improve outcomes. Incorporation of exercise-based CAM, pelvic floor physical therapy, acupuncture and cognitive behavioral therapy are suggested to show promising results but well powered randomized studies are needed to draw conclusions on their efficacy. Evidence for non-opioid alternatives such as oral cannabinoids are preliminary and may emerge to be safe and effective.

Using a behavioral model to identify factors associated with choice of provider for neck and low back pain: A systematic review

BACKGROUND

It remains unclear as to what factors influence a patient's choice to seek care from a specific healthcare provider for low back and neck pain.

OBJECTIVE

Utilize Andersen's Behavioral Model of Health Service Utilization as a conceptual framework to identify the predisposing, enabling and need factors associated with choice of healthcare provider for back and/or neck pain.

METHODS

PubMed, CINAHL, EMBASE, and SCOPUS databases were searched for studies that included 1) patients seeking care for acute or chronic low back or neck pain; 2) patients at least 18 years of age; 3) reported any healthcare provider type chosen to be seen. Significant factors addressing a patient's choice of provider seen for back pain, neck pain, or both were extracted from studies and analyzed under the Behavioral Model of Health Service Utilization.

RESULTS

20 studies were included in this review: 17 quantitative studies and 3 qualitative studies. Provider types identified were medical physicians, chiropractors, physical therapists, acupuncturists and CAM providers. Age and sex were the most commonly reported predisposing factors; financial and personal factors were the most common enabling factors; patients' duration of pain and self-reported level of functioning were the most commonly reported need factors.

CONCLUSIONS

While predisposing and need factors are important, enabling factors also have an influence in choice of healthcare provider for back and/or neck pain.

Yoga compared to non-exercise or physical therapy exercise on pain, disability, and quality of life for patients with chronic low back pain: A systematic review and meta-analysis of randomized controlled trials

Background

Chronic low back pain (CLBP) is a common and often disabling musculoskeletal condition. Yoga has been proven to be an effective therapy for chronic low back pain. However, there are still controversies about the effects of yoga at different follow-up periods and compared with other physical therapy exercises.

Objective

To critically compare the effects of yoga for patients with chronic low back pain on pain, disability, quality of life with non-exercise (e.g. usual care, education), physical therapy exercise.

Methods

This study was registered in PROSPERO, and the registration number was CRD42020159865. Randomized controlled trials (RCTs) of online databases included PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase which evaluated effects of yoga for patients with chronic low back pain on pain, disability, and quality of life were searched from inception time to November 1, 2019. Studies were eligible if they assessed at least one important outcome, namely pain, back-specific disability, quality of life. The Cochrane risk of bias tool was used to assess the methodological quality of included randomized controlled trials. The continuous outcomes were analyzed by calculating the mean difference (MD) or standardized mean difference (SMD) with 95% confidence intervals (CI) according to whether combining outcomes measured on different scales or not.

Results

A total of 18 randomized controlled trials were included in this meta-analysis. Yoga could significantly reduce pain at 4 to 8 weeks (MD = -0.83, 95% CI = -1.19 to -0.48, p<0.00001, I² = 0%), 3 months (MD = -0.43, 95% CI = -0.64 to -0.23, p<0.0001, I² = 0%), 6 to 7 months (MD = -0.56, 95% CI = -1.02 to -0.11, p = 0.02, I² = 50%), and was not significant in 12 months (MD = -0.52, 95% CI = -1.64 to 0.59, p = 0.36, I² = 87%) compared with non-exercise. Yoga was better than non-exercise on disability at 4 to 8 weeks (SMD = -0.30, 95% CI = -0.51 to -0.10, p = 0.003, I² = 0%), 3 months (SMD = -0.31, 95% CI = -0.45 to -0.18, p<0.00001, I² = 30%), 6 months (SMD = -0.38, 95% CI = -0.53 to -0.23, p<0.00001, I² = 0%), 12 months (SMD = -0.33, 95% CI = -0.54 to -0.12, p = 0.002, I² = 9%). There was no significant difference on pain, disability compared with physical therapy exercise group. Furthermore, it suggested that there was a non-significant difference on physical and mental quality of life between yoga and any other interventions.

Conclusion

This meta-analysis provided evidence from very low to moderate investigating the effectiveness of yoga for chronic low back pain patients at different time points. Yoga might decrease pain from short term to intermediate term and improve functional disability status from short term to long term compared with non-exercise (e.g. usual care, education). Yoga had the same effect on pain and disability as any other exercise or physical therapy. Yoga might not improve the physical and mental quality of life based on the result of a merging.

Comparing physicians' and patients' reporting on adverse reactions in randomized trials on acupuncture-a secondary data analysis

BACKGROUND

We aimed to compare patients' and physicians' safety reporting using data from large acupuncture trials (44,818 patients) and to determine associations between patient characteristics and reporting of adverse reactions.

METHODS

Six pragmatic randomized trials with an additional non-randomized study arm that included those patients who refused randomization were evaluated. Patients received acupuncture treatment for osteoarthritis of the hip or knee, chronic neck pain, chronic low back pain, chronic headache, dysmenorrhea, or allergic rhinitis or asthma. Safety outcomes were evaluated by questionnaires from both the physicians and the patients. To determine level of agreement between physicians and patients on the prevalence of adverse reactions, Cohen's kappa was used. With multilevel models associations between patient characteristics and reporting of adverse reactions were assessed.

RESULTS

Patients reported on average three times more adverse reactions than the study physicians: for bleeding/haematoma, 6.7% of patients (n = 2458) vs. 0.6% of physicians (n = 255) and for pain, 1.7% of patients (n = 636) vs. 0.5% of physicians (n = 207). We found only minor agreements between patients and physicians (maximum Cohen's kappa: 0.50, 95% confidence interval [0.49;0.51] for depressive mood). Being a female and participation in the randomization were associated with higher odds of reporting an adverse reaction.

CONCLUSIONS

In our study, patients' and physicians' reports on adverse reactions of acupuncture differed substantially, possibly due to differences in patients' and physicians' questionnaires and definitions. For the assessment of safety, we strongly support the inclusion of patients' and physicians' reports while ensuring standardization of data collection and definitions.

Primary care patients' use of conventional and complementary medicine for chronic low back pain

Purpose

To investigate among primary care patients and their physicians in western Switzerland the prevalence of use, perceived usefulness, and communication about common treatments for chronic or recurrent low back pain (crLBP) including complementary medicine (CM).

Patients and methods

A cross-sectional cluster observational study involving 499 crLBP patients visiting 45 primary care physicians (PCPs) was conducted from November 1, 2015, to May 31, 2016. Patients and primary care physicians completed questionnaires about lifetime use and usefulness of 30 crLBP therapies. We conducted multivariate analyses of factors associated with therapy use, including sociodemographic variables, pain duration, insurance coverage, and primary care physicians’ characteristics.

Results

The five most frequent modalities used at least once by patients were physiotherapy (81.8%), osteopathic treatment (63.4%), exercise therapy (53.4%), opioids (52.5%), and therapeutic massage (50.8%). For their PCPs, the five most useful therapies were physiotherapy, osteopathic treatment, yoga, meditation, and manual therapy. In multivariate analysis, the use of physiotherapy was significantly associated with longer pain duration; osteopathic treatment was associated with age under 75 years, female gender, higher education, and CM insurance coverage. Exercise therapy was associated with non-smoking and longer pain duration. Smokers were more likely and patients of PCPs with CM training were less likely to have used opioids. During their lifetime, 86.6% of the participants had used at least one CM therapy to manage their crLBP, with a mean of 3.3 (SD=2.9) therapies used per participant; 46.1% of participants reported that their PCP did not enquire about CM use. Among CM users, 64.7% informed their PCP about it.

Conclusion

Patients with crLBP use a variety of treatments, including self-prescribed and unreimbursed therapies, most frequently physiotherapy and osteopathy. The results suggest that PCPs should systematically discuss with their patients the treatments they tried to manage crLBP, including CM.

System Dynamics to Investigate Opioid Use and Chiropractic Care for Chronic Musculoskeletal Pain

OBJECTIVE

The purpose of this investigation was to create a system dynamics (SD) model, including published data and required assumptions, as a tool for future research identifying the role of chiropractic care in the management of chronic, nonmalignant pain in a Canadian population.

METHODS

We present an illustrative case description of how we evaluated the feasibility of conducting a large-scale clinical trial to assess the impact of chiropractic care in mitigating excessive opioid use in Canada. We applied SD modeling using current evidence and key assumptions where such evidence was lacking. Modeling outcomes were highlighted to determine which potential factors were necessary to account for compelling study designs.

RESULTS

Results suggest that a future clinical study diverting patients with nonmalignant musculoskeletal pain early to the chiropractic stream of care could be most effective. System dynamics modeling also highlighted design challenges resulting from unresearched assumptions that needed to be proxied for model completion. Assumptions included changing rates in opioid-associated deaths and rates of success in treatment management of addicted patients.

CONCLUSION

In this case, SD modeling identified current research gaps and strong contenders for appropriate follow-up questions in a clinical research domain, namely the role of chiropractic care in the management of chronic, nonmalignant pain in a Canadian population.

The use of complementary and alternative medicine (CAM) for pregnancy related low back and/ or pelvic girdle pain: An online survey

Low back and pelvic girdle pain (LBPGP) is a common complaint among pregnant women, which increases throughout pregnancy and women use various complementary and alternative medicine (CAM) therapies to manage their pain. Using an online survey, CAM treatments used by pregnant women in the UK and their perceptions of these therapies to relieve LBPGP were investigated. 191 women completed the survey and 70% experienced LBPGP lasting more than one week. Over half of women who sought treatment from a GP or physiotherapist were dissatisfied. 25% of participants used CAM during pregnancy, the most popular being aromatherapy (21%), acupuncture (21%), and reflexology (15%). 81% of women used CAM to manage their LBPGP and 85% found it useful for pregnancy symptoms. Women experience high levels of pain during pregnancy with limited treatment options. Research into effective CAM treatments for LBPGP is required to allow women to make informed decisions regarding treatment options.

Prevalence, patterns, and predictors of massage practitioner utilization: Results of a US nationally representative survey

BACKGROUND

The use of massage therapy is common, especially in patients with musculoskeletal pain. The purpose of this study was to examine the prevalence, utilization, socio-demographic and health-related predictors of massage practitioner consultations in the US population.

METHODS

Cross-sectional data from the 2012 National Health Interview Survey for adults (n = 34,525).

RESULTS

Prevalence of massage practitioner utilization were 12.8% (lifetime) and 6.8% (last 12 months). Compared to non-users, those who used massage in the last year were more likely: female, at least high school educated, annual income ≥ US$ 15,000, diagnosed with spinal pain or arthritis, report moderate physical activity level as compared to low level, and consume alcohol as compared to being abstinent. Massage was mainly used for general wellness or disease prevention (56.3%), but also for specific, typically musculoskeletal, health problems (41.9%) for which 85.2% reported massage helped to some or a great deal. Most (59.1%) did not disclose massage use to their health care provider, despite 69.4% reporting massage therapy combined with medical treatment would be helpful.

CONCLUSIONS

Approximately 7% (15.4 million) of US adults used massage therapy in the past year, mainly for general disease prevention, wellness or musculoskeletal pain. The majority of respondents reported positive outcomes of massage on specific health problems and overall well-being. Massage utilization was rarely covered by health insurance. Despite the majority of massage users considered massage therapy combined with medical care helpful, most did not disclose massage therapy use to their health care provider.

Reasons for continuing use of Complementary and Alternative Medicine (CAM) in students: a consumer commitment model

Background

Research on continued CAM use has been largely atheoretical and has not considered the broader range of psychological and behavioral factors that may be involved. The purpose of this study was to test a new conceptual model of commitment to CAM use that implicates utilitarian (trust in CAM) and symbolic (perceived fit with CAM) in psychological and behavioral dimensions of CAM commitment.

Methods

A student sample of CAM consumers, (N = 159) completed a survey about their CAM use, CAM-related values, intentions for future CAM use, CAM word-of-mouth behavior, and perceptions of being an ongoing CAM consumer.

Results

Analysis revealed that the utilitarian, symbolic, and CAM commitment variables were significantly related, with r’s ranging from .54 to .73. A series hierarchical regression analyses controlling for relevant demographic variables found that the utilitarian and symbolic values uniquely accounted for significant and substantial proportion of the variance in each of the three CAM commitment indicators (R² from .37 to .57).

Conclusions

The findings provide preliminary support for the new model that posits that CAM commitment is a multi-dimensional psychological state with behavioral indicators. Further research with large-scale samples and longitudinal designs is warranted to understand the potential value of the new model.

The effectiveness of manual therapy for the management of musculoskeletal disorders of the upper and lower extremities: a systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration

BACKGROUND

Musculoskeletal disorders (MSDs) of the upper and lower extremities are common in the general population and place a significant burden on the health care system. Manual therapy is recommended by clinical practice guidelines for the management of these injuries; however, there is limited evidence to support its effectiveness. The purpose of our review was to investigate the effectiveness of manual therapy in adults or children with MSDs of the upper or lower extremity.

METHODS

Randomized controlled trials (RCTs), cohort studies, and case-control studies evaluating the effectiveness of manual therapy were eligible. We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials from 1990 to 2015. Paired reviewers screened studies for relevance and critically appraised relevant studies using the Scottish Intercollegiate Guidelines Network criteria. Studies with low risk of bias were synthesized following best-evidence synthesis principles. Where available, we computed mean changes between groups, relative risks and 95 % CI.

RESULTS

We screened 6047 articles. Seven RCTs were critically appraised and three had low risk of bias. For adults with nonspecific shoulder pain of variable duration, cervicothoracic spinal manipulation and mobilization in addition to usual care may improve self-perceived recovery compared to usual care alone. For adults with subacromial impingement syndrome of variable duration, neck mobilization in addition to a multimodal shoulder program of care provides no added benefit. Finally, for adults with grade I-II ankle sprains of variable duration, lower extremity mobilization in addition to home exercise and advice provides greater short-term improvements in activities and function over home exercise and advice alone. No studies were included that evaluated the effectiveness of manual therapy in children or for the management of other extremity injuries in adults.

CONCLUSIONS

The current evidence on the effectiveness of manual therapy for MSDs of the upper and lower extremities is limited. The available evidence supports the use of manual therapy for non-specific shoulder pain and ankle sprains, but not for subacromial impingement syndrome in adults. Future research is needed to determine the effectiveness of manual therapy and guide clinical practice.

Attitudes Toward Chiropractic

We assessed the attitudes of Canadian obstetricians toward chiropractic with a 38-item cross-sectional survey. Ninety-one obstetricians completed the survey, for a response rate of 14% (91 of 659). Overall, 30% of respondents held positive views toward chiropractic, 37% were neutral, and 33% reported negative views. Most (77%) reported that chiropractic care was effective for some musculoskeletal complaints, but 74% disagreed that chiropractic had a role in treatment of non-musculoskeletal conditions. Forty percent of respondents referred at least some patients for chiropractic care each year, and 56% were interested in learning more about chiropractic care. Written comments from respondents revealed concerns regarding safety of spinal manipulation and variability among chiropractors. Canadian obstetricians’ attitudes toward chiropractic are diverse and referrals to chiropractic care for their patients who suffer from pregnancy-related low back pain are limited. Improved interprofessional relations may help optimize care of pregnant patients suffering from low back pain.

The effectiveness of soft-tissue therapy for the management of musculoskeletal disorders and injuries of the upper and lower extremities: A systematic review by the Ontario Protocol for Traffic Injury management (OPTIMa) collaboration

BACKGROUND

Soft-tissue therapy is commonly used to manage musculoskeletal injuries.

OBJECTIVE

To determine the effectiveness of soft-tissue therapy for the management of musculoskeletal disorders and injuries of the upper and lower extremities.

DESIGN

Systematic Review.

METHODS

We searched six databases from 1990 to 2015 and critically appraised eligible articles using Scottish Intercollegiate Guidelines Network (SIGN) criteria. Evidence from studies with low risk of bias was synthesized using best-evidence synthesis methodology.

RESULTS

We screened 9869 articles and critically appraised seven; six had low risk of bias. Localized relaxation massage provides added benefits to multimodal care immediately post-intervention for carpal tunnel syndrome. Movement re-education (contraction/passive stretching) provides better long-term benefit than one corticosteroid injection for lateral epicondylitis. Myofascial release improves outcomes compared to sham ultrasound for lateral epicondylitis. Diacutaneous fibrolysis (DF) or sham DF leads to similar outcomes in pain intensity for subacromial impingement syndrome. Trigger point therapy may provide limited or no additional benefit when combined with self-stretching for plantar fasciitis; however, myofascial release to the gastrocnemius, soleus and plantar fascia is effective.

CONCLUSION

Our review clarifies the role of soft-tissue therapy for the management of upper and lower extremity musculoskeletal disorders and injuries. Myofascial release therapy was effective for treating lateral epicondylitis and plantar fasciitis. Movement re-education was also effective for managing lateral epicondylitis. Localized relaxation massage combined with multimodal care may provide short-term benefit for treating carpal tunnel syndrome. More high quality research is needed to study the appropriateness and comparative effectiveness of this widely utilized form of treatment.

Acupuncture or low frequency infrared treatment for low back pain in Chinese patients: a discrete choice experiment

Acupuncture is a popular but controversial treatment option for low back pain. In China, it is practised as traditional Chinese medicine; other treatment strategies for low back pain are commonly practised as Western medicine. Research on patient preference for low back-pain treatment options has been mainly conducted in Western countries and is limited to a willingness-to-pay approach. A stated-preference, discrete choice experiment was conducted to determine Chinese patient preferences and trade-offs for acupuncture and low frequency infrared treatment in low back pain from September 2011 to August 2012 after approval from the Department of Scientific Research in the study settings. Eight-six adult outpatients who visited the 'traditional medicine department' at a traditional Chinese medicine hospital and the 'rehabilitation department' at a Western medicine hospital in Guangdong Province of China for chronic low back pain during study period participated in an interview survey. A questionnaire containing 10 scenarios (5 attributes in each scenario) was used to ask participants' preference for acupuncture, low frequency infrared treatment or neither option. Validated responses were analysed using a nested-logit model. The decision on whether to receive a therapy was not associated with the expected utility of receiving therapy, female gender and higher out-of-pocket payment significantly decreased chance to receive treatments. Of the utility of receiving either acupuncture or low frequency infrared treatment, the treatment sensation was the most important attribute as an indicator of treatment efficacy, followed by the maximum efficacy, maintenance duration and onset of efficacy, and the out-of-pocket payment. The willingness-to-pay for acupuncture and low frequency infrared treatment were about $618.6 and $592.4 USD per course respectively, demonstrated patients' demand of pain management. The treatment sensation was regarded as an indicator of treatment efficacy and the most important attribute for choosing acupuncture or low frequency infrared treatment. The high willingness-to-pay demonstrated patients' demand of pain management. However, there may be other factors influencing patients' preference to receive treatments.

Health-related self-perceptions over time and provider-based Complementary and Alternative Medicine (CAM) use in people with inflammatory bowel disease or arthritis

OBJECTIVES

To prospectively investigate how health-related self-perceptions are associated with use of provider-based CAM in two chronic inflammatory diseases, arthritis and inflammatory bowel disease (IBD).

DESIGN AND SETTING

A prospective online survey was administered to convenience samples of individuals with arthritis or inflammatory bowel disease, and a follow-up survey completed 6 months later. Participants were recruited via online ads, through national organizations, and support groups.

MAIN OUTCOME MEASURES

Surveys included measures of demographics, use of provider-delivered CAM, disease-related factors, self-perceptions of having a healthy lifestyle and being able to handle stress, and trait resilience.

RESULTS

325 people (170 with arthritis and 155 with IBD) completed the initial and follow-up surveys. Rates of CAM use were 43.2% and 45.9% for the arthritis and IBD groups, respectively. T-tests revealed significant differences on healthy lifestyle self-perceptions and trait resilience for both illness groups. Differences in self-perceptions about handling stress were only significant in the IBD group. Multivariate logistic regression controlling for demographics and health-related variables revealed that seeing oneself as having a healthy lifestyle predicted CAM use in both illness groups. Being resilient predicted CAM use only in the IBD group, and self-perceptions about handling stress predicted CAM use only in the arthritis group.

CONCLUSIONS

This study provides insights into how health-related self-perceptions are prospectively linked to provider-based CAM use in patients with chronic inflammatory disease. This information is important for both health-care practitioners and researchers as it has implications for maximizing the health-promoting aspects of CAM use and understanding CAM adherence.

Standardized versus Individualized Acupuncture for Chronic Low Back Pain: A Randomized Controlled Trial

We aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain. A single-center randomized controlled single-blind trial was performed in a general medical practice in Germany run by a Chinese-born medical doctor trained in western and Chinese medicine. One hundred and fifty outpatients with chronic low back pain were randomly allocated to two groups (78 standardized and 72 individualized acupuncture). Patients received either standardized acupuncture or individualized acupuncture. Treatment encompassed between 10 and 15 treatments based on individual symptoms with two treatments per week. The main outcome measure was the area under the curve (AUC) summarizing eight weeks of daily rated pain severity measured with a visual analogue scale (0 mm = no pain, 100 mm = worst imaginable pain). No significant differences between groups were observed for the AUC (individualized acupuncture mean: 1768.7 (95% CI, 1460.4; 2077.1); standardized acupuncture 1482.9 (1177.2; 1788.7); group difference, 285.8 (-33.9; 605.5) P = 0.080). In this single-center trial, individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain. As a next step, a multicenter noninferiority study should be performed to investigate whether standardised acupuncture treatment for chronic low back pain might be applicable in a broader usual care setting. This trial is registered with ClinicalTrials.gov NCT00758017.

Features of complementary and alternative medicine use by patients with coronary artery disease in Beijing: a cross-sectional study

Background

Complementary and alternative medicine (CAM) is commonly used in China for the management of coronary artery disease (CAD). However, few studies have been conducted to investigate the prevalence, perceived effectiveness, types, and reasons of CAM use in patients diagnosed with CAD.

Methods

A cross-sectional study design was adopted. Questionnaires were distributed at the outpatient cardiac clinics of four tertiary-level teaching general hospitals in Beijing. Quantitative data were analyzed using Student’s t-test. Categorical data were analyzed using chi-square test. Logistic regression was employed to explore factors associated with the use of CAM as well as CAM use features in Chinese medicine (CM) hospitals when significant differences were found upon comparisons.

Results

From May to July, 2009, a total of 600 questionnaires were distributed, and 546 patients with a diagnosis of CAD responded with valid values and were included in the present study. CAM was used by 69.1% of the patients with CAD; the majority (75.9%) of these CAM users believes that CAM is effective. “Few side effects” (49.6%) was the main reason of CAM use; whereas “doubt of effect” (61.5%) was the main reason for non-use. Patent herbal medicine (90.7%) was the most commonly used CAM type. Compared with non-CAM users, CAM users tended to be older (p < 0.01), have a longer disease duration (p = 0.02) and better current health status. In addition, CAM users had significant lower odds for emergency admission and hospitalization within the past one year. Patients with CAD from CM and WM hospitals differ in CAM use frequency, types, perceived effectiveness, as well as reasons for CAM use or non-CAM use.

Conclusion

The present study suggested a group of significant factors which could influence the use of CAM in patients with CAD. CAM use patterns differ in patients from CM and WM hospitals.

Yoga for chronic low back pain: a meta-analysis of randomized controlled trials

OBJECTIVES

To evaluate the efficacy of yoga as an intervention for chronic low back pain (CLBP) using a meta-analytical approach. Randomized controlled trials (RCTs) that examined pain and⁄or functional disability as treatment outcomes were included. Post-treatment and follow-up outcomes were assessed.

METHODS

A comprehensive search of relevant electronic databases, from the time of their inception until November 2011, was conducted. Cohen's d effect sizes were calculated and entered in a random-effects model.

RESULTS

Eight RCTs met the criteria for inclusion (eight assessing functional disability and five assessing pain) and involved a total of 743 patients. At post-treatment, yoga had a medium to large effect on functional disability (d=0.645) and pain (d=0.623). Despite a wide range of yoga styles and treatment durations, heterogeneity in post-treatment effect sizes was low. Follow-up effect sizes for functional disability and pain were smaller, but remained significant (d=0.397 and d=0.486, respectively); however, there was a moderate to high level of variability in these effect sizes.

DISCUSSION

The results of the present study indicate that yoga may be an efficacious adjunctive treatment for CLBP. The strongest and most consistent evidence emerged for the short-term benefits of yoga on functional disability. However, before any definitive conclusions can be drawn, there are a number of methodological concerns that need to be addressed. In particular, it is recommended that future RCTs include an active control group to determine whether yoga has specific treatment effects and whether yoga offers any advantages over traditional exercise programs and other alternative therapies for CLBP.

Prevalence of claims-based recurrent low back pain in a Canadian population: a secondary analysis of an administrative database

Background

There is a vast literature reporting that the point prevalence of low back pain (LBP) is high and increasing. It is also known that a large proportion of acute LBP episodes are recurrent within 12 months. However, few studies report the annual trends in the prevalence of recurrent LBP or describe these trends according to age and sex categories.

Methods

We conducted a retrospective cohort study involving 401 264 adults selected from the administrative database of physician claims for the province of Quebec, Canada. These adults, aged 18 years and over, met the criteria of having consulted a physician three times within a 365-day period between 2000 and 2007 for a LBP condition corresponding to ICD-9 codes 721, 722, 724 or 739. All data were analyzed by sex and clustered according to specific age categories.

Results

We observed a decrease from 1.64% to 1.33% in the annual prevalence between 2000 and 2007 for men. This decrease in prevalence was mostly observed between 35 and 59 years of age. Older (≥65 years) women were 1.35 times more at risk to consult a physician for LBP in a recurrent manner than older men. The most frequently reported diagnosis was non-specific LBP between 2000 to 2007. During the same period, sequelae of previous back surgery and spinal stenosis were the categories with the largest increases.

Conclusion

The annual prevalence of claims-based recurrent LBP progressively decreased between 2000 and 2007 for younger adults (<65 years) while older adults (≥65 years) showed an increase. Given the aging Canadian population, recurrent low back pain could have an increasing impact on the quality of life of the elderly as well as on the healthcare system.

Use of complementary and alternative medicine by mid-age women with back pain: a national cross-sectional survey

BACKGROUND

The use of complementary and alternative medicine (CAM) has increased significantly in Australia over the past decade. Back pain represents a common context for CAM use, with increasing utilisation of a wide range of therapies provided within and outside conventional medical facilities. We examine the relationship between back pain and use of CAM and conventional medicine in a national cohort of mid-aged Australian women.

METHODS

Data is taken from a cross-sectional survey (n = 10492) of the mid-aged cohort of the Australian Longitudinal Study on Women's Health, surveyed in 2007. The main outcome measures were: incidence of back pain the previous 12 months, and frequency of use of conventional or CAM treatments in the previous 12 months.

RESULTS

Back pain was experienced by 77% (n = 8063) of the cohort in the previous twelve month period. The majority of women with back pain only consulted with a conventional care provider (51.3%), 44.2% of women with back pain consulted with both a conventional care provider and a CAM practitioner. Women with more frequent back pain were more likely to consult a CAM practitioner, as well as seek conventional care. The most commonly utilised CAM practitioners were massage therapy (26.5% of those with back pain) and chiropractic (16.1% of those with back pain). Only 1.7% of women with back pain consulted with a CAM practitioner exclusively.

CONCLUSIONS

Mid-aged women with back pain utilise a range of conventional and CAM treatments. Consultation with CAM practitioners or self-prescribed CAM was predominantly in addition to, rather than a replacement for, conventional care. It is important that health professionals are aware of potential multiple practitioner usage in the context of back pain and are prepared to discuss such behaviours and practices with their patients.

Substitutes or complements? An exploration of the effect of wait times and availability of conventional care on the use of alternative health therapies in Canada

OBJECTIVES

We explore how alternative and complementary care use is affected by wait list length and availability of conventional care in Canada.

DESIGN

We use data from the 2003 Canadian Community Health Survey, Statistics Canada and the Fraser Institute to explore the effect of longer wait times on the use of alternative therapies in general and for specific therapies: Registered Massage Therapy, Chiropractics, Physiotherapy, Homeopathy and Acupuncture.

OUTCOME MEASURES

We use binary variables indicating whether the individual used various types of alternative care in the year preceding the survey.

RESULTS

Wait times for specialists are associated with lower probabilities of using alternative care, but the effect are usually not statistically significant. Longer wait times for non-emergency surgery are associated with lower probabilities of using alternative care when using data from CANSIM, but very small higher probabilities of using alternative care when using data from the Fraser Institute which includes wait times for treatments for other procedures than non-emergency surgery. We find positive but extremely small effects for total wait times from the Fraser Institute. Individuals reporting unmet health care needs are more likely to use alternative care while individuals who do not have a regular physician are less likely to use it.

CONCLUSIONS

Reporting unmet health care needs or no family physician have more of an impact on the use of alternative therapies than wait lists do. The evidence is not clear as to whether alternative care is sometimes used as a substitute to conventional care rather than a complement.

Treatment Preferences for CAM in children with chronic pain

CAM therapies have become increasingly popular in pediatric populations. Yet, little is known about children's preferences for CAM. This study examined treatment preferences in chronic pediatric pain patients offered a choice of CAM therapies for their pain. Participants were 129 children (94 girls) (mean age = 14.5 years ± 2.4; range = 8–18 years) presenting at a multidisciplinary, tertiary clinic specializing in pediatric chronic pain. Bivariate and multivariate analyses were used to examine the relationships between CAM treatment preferences and patient's sociodemographic and clinical characteristics, as well as their self-reported level of functioning. Over 60% of patients elected to try at least one CAM approach for pain. The most popular CAM therapies were biofeedback, yoga and hypnosis; the least popular were art therapy and energy healing, with craniosacral, acupuncture and massage being intermediate. Patients with a diagnosis of fibromyalgia (80%) were the most likely to try CAM versus those with other pain diagnoses. In multivariate analyses, pain duration emerged as a significant predictor of CAM preferences. For mind-based approaches (i.e. hypnosis, biofeedback and art therapy), pain duration and limitations in family activities were both significant predictors. When given a choice of CAM therapies, this sample of children with chronic pain, irrespective of pain diagnosis, preferred non-invasive approaches that enhanced relaxation and increased somatic control. Longer duration of pain and greater impairment in functioning, particularly during family activities increased the likelihood that such patients agreed to engage in CAM treatments, especially those that were categorized as mind-based modalities.

Patients visiting the complementary medicine clinic for pain: a cross sectional study

Background

Pain is one of the most common reasons for seeking medical care. The purpose of this study was to characterize patients visiting the complementary medicine clinic for a pain complaint.

Methods

This is a cross-sectional study. The study took place at Clalit Health Services (CHS) complementary clinic in Beer-Sheva, Israel. Patients visiting the complementary clinic, aged 18 years old and older, Hebrew speakers, with a main complaint of pain were included. Patients were recruited consecutively on random days of the month during a period of six months. Main outcome measures were: pain levels, location of pain, and interference with daily activities. Once informed consent was signed patients were interviewed using a structured questionnaire by a qualified nurse. The questionnaire included socio-demographic data, and the Brief Pain Inventory (BPI).

Results

Three-hundred and ninety-five patients were seen at the complementary medicine clinic during the study period, 201 (50.8%) of them met the inclusion criteria. Of them, 163 (81.1%) agreed to participate in the study and were interviewed. Pain complaints included: 69 patients (46.6%) with back pain, 65 (43.9%) knee pain, and 28 (32.4%) other limbs pain. Eighty-two patients (50.3%) treated their pain with complementary medicine as a supplement for their conventional treatment, and 55 (33.7%) felt disappointed from the conventional medicine experience. Eighty-three patients (50.9%) claimed that complementary medicine can result in better physical strength, or better mental state 51 (31.3%). Thirty-seven patients (22.7%) were hoping that complementary medicine will prevent invasive procedures.

Conclusion

Given the high proportion of patients with unsatisfactory pain relief using complementary and alternative medicine (CAM), general practitioners should gain knowledge about CAM and CAM providers should gain training in pain topics to improve communication and counsel patients. More clinical research to evaluate safety and efficiency of CAM for pain is needed to provide evidence based counseling.

Use of complementary and alternative medicine by those with a chronic disease and the general population--results of a national population based survey

Background

The use of complementary and alternative medicine (CAM) is becoming more common, but population-based descriptions of its patterns of use are lacking. This study aimed to determine the prevalence of CAM use in the general population and for those with asthma, diabetes, epilepsy and migraine.

Methods

Data from cycles 1.1, 2.1 and 3.1 of the Canadian Community Health Survey (CCHS) were used for the study. The CCHS is a national cross-sectional survey administered to 400,055 Canadians aged ≥12 between 2001-2005. Self-reported information about professionally diagnosed health conditions was elicited. CCHS surveys use a multistage stratified cluster design to randomly select a representative sample of Canadian household residents. Descriptive data on the utilization of CAM services was calculated and logistic regression was used to determine what sociodemographic factors predict CAM use.

Results

Weighted estimates show that 12.4% (95% Confidence Interval (CI): 12.2-12.5) of Canadians visited a CAM practitioner in the year they were surveyed; this rate was significantly higher for those with asthma 15.1% (95% CI: 14.5-15.7) and migraine 19.0% (95% CI: 18.4-19.6), and significantly lower for those with diabetes 8.0% (95% CI: 7.4-8.6) while the rate in those with epilepsy (10.3%, 95% CI: 8.4-12.2) was not significantly different from the general population.

Conclusion

A large proportion of Canadians use CAM services. Physicians should be aware that their patients may be accessing other services and should be prepared to ask and answer questions about the risks and benefits of CAM services in conjunction with standard medical care.

Back pain amongst 8,910 young Australian women: a longitudinal analysis of the use of conventional providers, complementary and alternative medicine (CAM) practitioners and self-prescribed CAM

Back problems and back pain are amongst the most prevalent conditions afflicting Australians and carry high direct and indirect costs for the health care systems of all developed countries. A major gap in the research literature on this topic is the longitudinal analysis of health seeking behaviour for people with back pain. All studies to date have been cross-sectional and it is important that the use of different providers (both conventional and complementary and alternative medicine, CAM) is examined over time. This study analysed data from a longitudinal study conducted over a 3-year period on 8,910 young Australian women. Information on health service use, self-prescribed treatments, and health status was obtained from two questionnaires mailed to study participants in 2003 and 2006. We found that there is little difference in the consultation practises or use of self-prescribed CAM between women who recently sought help for back pain and women who had longer-term back pain; the only difference being that women with longer-term back pain consulted more with chiropractors. We conclude that women who seek help for their back pain are frequent visitors to a range of conventional and CAM practitioners and are also high users of self-prescribed CAM treatments. The frequent use of a range of conventional providers and practitioner-based and self-prescribed CAM amongst women with back pain warrants further investigation.

Management of low back pain in primary care prior to multidisciplinary functional restoration: a retrospective study of 72 patients

OBJECTIVE

Chronic low back pain is a major socioeconomic health issue, due to the high direct (healthcare) and indirect (sick leave) costs. The aim of the present study was to describe the primary care management of low back pain patients prior to their inclusion in a multidisciplinary functional restoration network.

METHODS

A descriptive, retrospective, questionnaire-based survey of the general practitioners dealing with 72 low back pain patients.

RESULTS

Patients had been monitored by their general practitioner for an average of four years, with a mean frequency of eight appointments per year per patient. Ninety-three percent and 60% of the patients had been referred to a rheumatologist and a surgeon, respectively. Ninety-eight percent had had lumbar radiographies, 80% had undergone a computed tomography scan and 64% had undergone magnetic resonance imaging. The most commonly prescribed medications were anti-inflammatories and first- or second-line analgesics. Thirty percent had already received morphine analgesics and 50% had taken antidepressants. Thirty-two percent had undergone lumbar surgery. Physiotherapy was frequently reported and, indeed, 6% of patients had participated in over 100 sessions. Total sick leave averaged 8.25 months over the study's follow-up period.

CONCLUSION

The time interval before referral to a multidisciplinary care team is long and so GPs should be encouraged and helped to organize this process earlier. It is also essential to determine factors which predict progression to chronic LBP.

When one door closes, another door opens: physician availability and motivations to consult complementary and alternative medicine providers

The aim of this study was to examine the attitudes, behaviours, and intentions to consult complementary and alternative medicine (CAM) providers, of health-care consumers living in a region with low physician availability. A survey was completed by a convenience sample of 235 CAM clients and nonconsumers recruited from an underserved urban centre in Canada. Nearly half had experienced difficulties getting an appointment with a physician when needed, and those who had experienced difficulties were more dissatisfied with conventional health care. Most participants (85.1%) indicated that they would consider consulting a CAM provider should they have difficulty getting an appointment with a physician in the future, including nearly 60% of the CAM nonconsumers. Participants who had more experience with CAM, greater perceived control over their symptoms, and were dissatisfied with conventional health care, were more likely to express intentions to use CAM should they experience access difficulties in the future. By situating the motivations for CAM within the context of physician availability our findings highlight the importance of geographical context, or place, for understanding attitudes towards CAM and its utilisation.

The use of expertise-based randomized controlled trials to assess spinal manipulation and acupuncture for low back pain: a systematic review

STUDY DESIGN

Systematic review.

OBJECTIVE

To assess current use of expertise-based randomization in trials of acupuncture or spinal manipulation for low back pain.

SUMMARY OF BACKGROUND DATA

The randomized clinical trial is often referred to as the gold standard for providing evidence to guide therapeutic decisions. Random allocation of participants to intervention and control groups theoretically should balance these groups for both known and unknown prognostic factors; however, when randomizing patients to competing interventions in which the clinician's skill is a central aspect of the intervention, (e.g., surgery, chiropractic, rehabilitation) a differential expertise bias may exist if a majority of clinicians participating have greater expertise in 1 of the 2 interventions under evaluation. Randomizing patients to therapists experienced in the interventions under investigation can overcome this bias.

METHODS

We systematically identified relevant randomized controlled trials published up to December 2005. Two independent reviewers extracted data in duplicate using a standardized form.

RESULTS

Of 12 eligible trials, none made use of an expertise-based randomized trial design.

CONCLUSION

Investigators designing acupuncture or spinal manipulation trials in which 2 or more active therapies are compared should consider expertise-based randomization to increase the validity and feasibility of their efforts.

Use of complementary alternative medicine for low back pain consulting in general practice: a cohort study

Background

Although back pain is considered one of the most frequent reasons why patients seek complementary and alternative medical (CAM) therapies little is known on the extent patients are actually using CAM for back pain.

Methods

This is a post hoc analysis of a longitudinal prospective cohort study embedded in a RCT. General practitioners (GPs) recruited consecutively adult patients presenting with LBP. Data on physical function, on subjective mood, and on utilization of health services was collected at the first consultation and at follow-up telephone interviews for a period of twelve months

Results

A total of 691 (51%) respectively 928 (69%) out of 1,342 patients received one form of CAM depending on the definition. Local heat, massage, and spinal manipulation were the forms of CAM most commonly offered. Using CAM was associated with specialist care, chronic LBP and treatment in a rehabilitation facility. Receiving spinal manipulation, acupuncture or TENS was associated with consulting a GP providing these services. Apart from chronicity disease related factors like functional capacity or pain only showed weak or no association with receiving CAM.

Conclusion

The frequent use of CAM for LBP demonstrates that CAM is popular in patients and doctors alike. The observed association with a treatment in a rehabilitation facility or with specialist consultations rather reflects professional preferences of the physicians than a clear medical indication. The observed dependence on providers and provider related services, as well as a significant proportion receiving CAM that did not meet the so far established selection criteria suggests some arbitrary use of CAM.
