Consumer characteristics and perceptions of chiropractic and chiropractic services in Australia: Results from a cross-sectional survey

OBJECTIVE The purpose of this study was to describe patient characteristics and summarize their perceptions of chiropractic in Australia. METHODS This study is part of a broader study aiming to extend the knowledge of the role of chiropractic within the current health care environment. A 33-item, paper-based, cross-sectional survey of a sample of patients from 100 systematically sampled chiropractic clinics from all the states and territories of Australia was conducted. The survey focused on patient demographics, socioeconomic status, perceived health status, and perceptions of chiropractic and chiropractic services. RESULTS A total of 486 responses were received (24.3% response rate). Respondents were predominantly female patients (67.1%) of the 45- to 64-year age group. Approximately half of the respondents reported a pretax annual income exceeding

The biopsychosocial model and hypothyroidism

40000. Most patients sought chiropractic services because of musculoskeletal disorders (68.7%) and for general health (21.2%), and personal beliefs motivated most respondents (70.2%) to visit a chiropractor. Most respondents would seek the chiropractic services again (97.5%) and were satisfied with the service received. CONCLUSIONS The results of this study show that the typical chiropractic patient in Australia is a middle-aged woman with a moderate to high income. Although only a small proportion of the Australian population sees a chiropractor, this group seems to be satisfied with the service.

The reporting of adverse events following spinal manipulation in randomized clinical trials-a systematic review.

This paper comments on the role and emergence of the biopsychosocial model in modern medical literature and health care settings. The evolution of the biopsychosocial model and its close association with modern pain theory is also examined. This paper seeks to discuss the place of this model with respect to the management of hypothyroidism. This discussion represents a forerunner to a randomised control trial that will seek to investigate the effect of a biopsychosocial-based treatment regime on hypothyroidism.

The influence of a biopsychosocial-based treatment approach to primary overt hypothyroidism: a protocol for a pilot study

BACKGROUND CONTEXT Spinal manipulative therapy (SMT) is commonly used to treat spinal disorders. Although clinical practice guidelines recommend the use of SMT in the treatment of neck and back disorders, concerns exist about the nature and incidence of adverse events associated with the intervention. Comprehensive reporting of adverse events in clinical trials could allow for accurate incidence estimates through meta-analysis. However, it is not clear if randomized clinical trials (RCTs) that involve SMT are currently reporting adverse events adequately. PURPOSE This study aimed to describe the extent of adverse events reporting in published RCTs involving SMT, and to determine whether the quality of reporting has improved since publication of the 2010 Consolidated Standards Of Reporting Trials (CONSORT) statement. STUDY DESIGN This is a systematic literature review. METHODS The Physiotherapy Evidence Database (PEDro) and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCTs involving SMT. Domains of interest included classifications of adverse events, completeness of adverse events reporting, nomenclature used to describe the events, methodological quality of the study, and details of the publishing journal. Data were analyzed using descriptive statistics. Frequencies and proportions of trials reporting on each of the specified domains above were calculated. Differences in proportions between pre- and post-CONSORT trials were calculated with 95% confidence intervals using standard methods, and statistical comparisons were analyzed using tests for equality of proportions with continuity correction. There was no funding obtained for this study. The authors declare no conflict of interest. RESULTS Of 7,398 records identified in the electronic searches, 368 articles were eligible for inclusion in this review. Adverse events were reported in 140 (38.0%) articles. There was a significant increase in the reporting of adverse events post-CONSORT (p=.001). There were two major adverse events reported (0.3%). Only 22 articles (15.7%) reported on adverse events in the abstract. There were no differences in reporting of adverse events post-CONSORT for any of the chosen parameters. CONCLUSIONS Although there has been an increase in reporting adverse events since the introduction of the 2010 CONSORT guidelines, the current level should be seen as inadequate and unacceptable. We recommend that authors adhere to the CONSORT statement when reporting adverse events associated with RCTs that involve SMT.

The Use of Spinal Manipulative Therapy in the Management of Chronic Obstructive Pulmonary Disease: A Systematic Review

BackgroundHypothyroidism is a prevalent endocrine condition. Individuals with this disease are commonly managed through supplementation with synthetic thyroid hormone, with the aim of alleviating symptoms and restoring normal thyroid stimulating hormone levels. Generally this management strategy is effective and well tolerated. However, there is research to suggest that a significant proportion of hypothyroid sufferers are being inadequately managed. Furthermore, hypothyroid patients are more likely to have a decreased sense of well-being and more commonly experience constitutional and neuropsychiatric complaints, even with pharmacological intervention.The current management of hypothyroidism follows a biomedical model. Little consideration has been given to a biopsychosocial approach to this condition. Within the chiropractic profession there is growing support for the use of a biopsychosocial-based intervention called Neuro-Emotional Technique (NET) for this population.Methods/DesignA placebo-controlled, single-blinded, randomised clinical pilot-trial has been designed to assess the influence of Neuro-Emotional Technique on a population with primary overt hypothyroidism. A sample of 102 adults (≥18 years) who meet the inclusion criteria will be randomised to either a treatment group or a placebo group. Each group will receive ten treatments (NET or placebo) over a six week period, and will be monitored for six months. The primary outcome will involve the measurement of depression using the Depression, Anxiety and Stress Scale (DASS). The secondary outcome measures to be used are; serum thyroid stimulating hormone, serum free-thyroxine, serum free-triiodothyronine, serum thyroid peroxidase auto-antibodies, serum thyroglobulin auto-antibodies as well as the measurement of functional health and well-being using the Short-Form-36 Version 2. The emotional states of anxiety and stress will be measured using the DASS. Self-measurement of basal heart rate and basal temperature will also be included among the secondary outcome measures. The primary and secondary measures will be obtained at commencement, six weeks and six months. Measures of basal heart rate and basal temperature will be obtained daily for the six month trial period, with recording to commence one week prior to the intervention.DiscussionThe study will provide information on the influence of NET when added to existing management regimens in individuals with primary overt hypothyroidism.Trial RegistrationANZCTR Number: 12607000040460

Risk of Recurrence of Low Back Pain: A Systematic Review

OBJECTIVES To evaluate the methodologic quality of the evidence for the use of spinal manipulative therapy (SMT) with and without other therapies in the management of chronic obstructive pulmonary disease (COPD). DESIGN A systematic review of the literature. PARTICIPANTS Any participant of a primary research study that investigated the effect of SMT on COPD. Only studies with participants older than age 18 years with an existing diagnosis of COPD were included. INTERVENTIONS Interventions included any form of high-velocity, low-amplitude spinal manipulation with or without other forms of manual therapy, exercise, and/or pharmacologic intervention. OUTCOME MEASURES Six-minute walking test, forced expiratory volume in 1 second, forced vital capacity, residual volume, total lung capacity, Chronic Respiratory Questionnaire, St Georges Respiratory Questionnaire, and the Hospital Anxiety and Depression Scale. RESULTS Six articles met all of the inclusion criteria and were included in the review: three randomized controlled trials (RCTs), one pre-post observational study, one case series, and one single case study. Sample sizes varied from 1 to 33 participants ranging in age from 55 to 85 years. Risk of bias was low for the three RCTs and high for the other studies. All three RCTs used SMT in conjunction with exercise from a pulmonary rehabilitation program. Five of the six studies reported improvements in lung function and exercise performance following SMT intervention. CONCLUSIONS This review provides a methodologic evaluation of the evidence for using SMT with and without other therapies in the management of COPD. While the quality of the evidence provided by three RCTs was high, they were all conducted on small sample sizes. These results highlight the need for further research into the use of SMT in conjunction with exercise on people with COPD.

Predictive factors for reporting adverse events following spinal manipulation in randomized clinical trials – secondary analysis of a systematic review

STUDY DESIGN: Systematic review. BACKGROUND: While most people with acute low back pain (LBP) recover quickly, recurrences are believed to be common. To our knowledge, no published high‐quality systematic review has assessed the risk of recurrent LBP or the factors that would predict LBP recurrence. OBJECTIVES: The aim of this study was to investigate the risk of, and prognostic factors for, a recurrence of LBP in patients who have recovered from a previous episode of LBP within the last year. METHODS: Systematic searches were conducted in the MEDLINE, Embase, and CINAHL databases. We included longitudinal studies of adults who had recovered from a previous episode of LBP within 12 months. The primary outcome was a new episode of LBP. Secondary outcomes were other types of recurrence (eg, episodes causing care seeking). RESULTS: Eight studies were included in the review: 7 observational studies and 1 randomized trial (2 publications). Six studies reported recurrence proportions for the primary outcome of an episode of LBP. Meta‐analysis was not conducted due to the low quality and heterogeneity of studies. Only 1 study was considered an inception cohort study; it reported a 1‐year recurrence proportion of 33%. A history of previous episodes of LBP prior to the most recent episode was the only factor that consistently predicted recurrence of LBP. CONCLUSION: The available research does not provide robust estimates of the risk of LBP recurrence and provides little information about factors that predict recurrence in people recently recovered from an episode of LBP. LEVEL OF EVIDENCE: Prognosis, 1a‐. Prospectively registered in PROSPERO on February 9, 2016 (CRD42016030220).

A biopsychosocial approach to primary hypothyroidism: Treatment and harms data from a randomized controlled trial

While spinal manipulative therapy (SMT) is recommended for the treatment of spinal disorders, concerns exist about adverse events associated with the intervention. Adequate reporting of adverse events in clinical trials would allow for more accurate estimations of incidence statistics through meta-analysis. However, it is not currently known if there are factors influencing adverse events reporting following SMT in randomized clinical trials (RCTs). Thus our objective was to investigate predictive factors for the reporting of adverse events in published RCTs involving SMT. The Physiotherapy Evidence Database (PEDro) and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCTs involving SMT. Domains of interest included: sample size; publication date relative to the 2010 CONSORT statement; risk of bias; the region treated; and number of intervention sessions. 7398 records were identified, of which 368 articles were eligible for inclusion. A total of 140 (38.0%) articles reported on adverse events. Articles were more likely to report on adverse events if they possessed larger sample sizes, were published after the 2010 CONSORT statement, had a low risk of bias and involved multiple intervention sessions. The region treated was not a significant predictor for reporting on adverse events. Predictors for reporting on adverse events included larger sample size, publication after the 2010 CONSORT statement, low risk of bias and trials involving multiple intervention sessions. We recommend that researchers focus on developing robust methodologies and participant follow-up regimens for RCTs involving SMT.

On Cobb angles, flexibility, and lumbar strength measurements

BackgroundHypothyroidism is a common endocrine condition. There is evidence to suggest that, for a proportion of sufferers, the standard medical treatment does not completely reverse the constitutional and neuropsychiatric symptoms brought about by this condition. The management of hypothyroidism follows a biomedical model with little consideration given to alternative management approaches. There exists anecdotal evidence and case reports supporting the use of a biopsychosocial-based intervention called Neuro-Emotional Technique (NET) for this population. The aim of this study was to explore the potential short-medium term clinical efficacy and safety of NET for individuals with primary hypothyroidism.DesignPlacebo-controlled, blinded, parallel groups, randomized trial.MethodsNinety adults with a diagnosis of primary hypothyroidism were recruited from Sydney, Australia. Blinded participants were randomized to either the NET or placebo group and received ten intervention sessions over a six week period. The primary outcome involved the measurement of states of depression using the DASS-42 questionnaire. Secondary outcomes included thyroid function, thyroid autoimmunity testing, SF-36v2 questionnaire, resting heart rate and temperature measurement. Outcomes were obtained at baseline, seven weeks and six months. Questionnaires were completed at the private clinics, and serum measures were obtained and analysed at commercial pathology company locations. Heart rate and temperature were also measured daily by participants. Linear mixed-effects models were used to analyse the continuous outcomes. Unadjusted odds ratios with 95% confidence intervals were calculated for the binary outcomes.ResultsParticipants were randomly allocated to the NET (n=44) and placebo (n=46) groups. A proportion of the sample displayed neuropsychiatric disturbances and alterations in quality of life measures at baseline. There were no statistically significant or clinically relevant changes in the primary or secondary outcomes between the NET and placebo groups at time seven weeks or six months. There were a few short-lived minor adverse events reported in both the NET and placebo groups that coincided with the application of the intervention.ConclusionsThe application of the NET intervention appears to be safe, but did not confer any clinical benefit to the participants in this study and is unlikely to be of therapeutic use in a hypothyroid population.Clinical trials registration numberAustralian and New Zealand Clinical Trials Registry Number: 12607000040460.
