Induced leg length inequality affects pelvis orientation during upright standing immediately following a sit-to-stand transfer: a pre-post measurement study.

BACKGROUND: Leg length inequality (LLI) greater than 20 mm has been associated with low back pain (LBP) and its correction is clinically recommended. Much less is known about the biomechanical effects that LLI below 15 mm has on pelvis orientation. METHODS: Twenty-two adult participants (8 female) aged between 18 and 30 years without LBP were enrolled in the study and completed a series of sit-to-stand trials with no heel-lift (0 mm baseline) and heel-lifts of varying heights (5, 9 and 12 mm) placed in their right shoe. Three-dimensional kinematic data were obtained from the lower extremities, pelvis and thorax. Additional kinematic data were obtained from the left and right sides of the pelvis. The global orientation of the whole pelvis and relative orientation between the left and right sides of the pelvis were obtained in upright standing immediately upon completion of the sit-to-stand movement. Repeated measures ANOVAs were used to detect differences in sample means across the different levels of heel-lift (0, 5, 9, and 12 mm). The tests for within-subject effects determined overall significant differences between the means at the different levels of heel-lift induced LLI. Partial Eta-Squared was used to express the size for the main effect of heel-lift height. For each level of heel-lift, the estimated marginal mean and 95% confidence interval (95%CI) values of pelvis angles were illustrated graphically. RESULTS: Left frontal plane rotation of the pelvis increased (p = 0.001), that is, the left side of the pelvis was lower than the right side of the pelvis, and anterior tilt of the pelvis decreased (p = 0.020) with a heel-lift height (applied on the right) as low as 5 mm. A significant main effect of heel-lift was only observed for the norm of rotations about all three axes for relative-pelvis orientation (p = 0.034). Post-hoc analyses did not reveal any statistically significant differences between the heel-lifts and the 0 mm baseline (p≥0.072). CONCLUSION: These findings suggest that correcting leg length inequality below the recommended threshold of 20 mm may influence pelvic orientation. Future work can investigate the effects of the altered orientations on spine loading and the clinical effects of corrections to minor leg length inequality.

Factors that influence scope of practice of the five largest health care professions in Australia: a scoping review.

INTRODUCTION: A well-functioning health system delivers quality services to all people when and where they need them. To help navigate the complex realm of patient care, it is essential that health care professions have a thorough understanding of their scope of practice. However, a lack of uniformity regarding scope of practice across the regulated health professions in Australia currently exists. This has led to ambiguity about what comprises scope of practice in some health care professions in the region. OBJECTIVE: The objective of this review was to explore the literature on the factors that influence scope of practice of the five largest health care professions in Australia. METHODS: This study employed scoping review methodology to document the current state of the literature on factors that influence scope of practice of the five largest health care professions in Australia. The search was conducted using the following databases: AMED (Allied and Complementary Medicine Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), Cochrane Library, EMBASE (Excerpta Medica Database), MANTIS (Manual, Alternative and Natural Therapy Index System), MEDLINE, PubMed, and SCOPUS. Additional data sources were searched from Google and ProQuest. RESULTS: A total of 12 771 publications were identified from the literature search. Twenty-three documents fulfilled the inclusion criteria and were included in the final analysis. Eight factors were identified across three professions (nursing & midwifery, pharmacy and physiotherapy) that influenced scope of practice: education, competency, professional identity, role confusion, legislation and regulatory policies, organisational structures, financial factors, and professional and personal factors. CONCLUSION: The results of this study will inform a range of stakeholders including the private and public arms of the healthcare system, educators, employers, funding bodies, policymakers and practitioners about the factors that influence scope of practice of health professions in Australia.

Predictors of chronic obstructive pulmonary disease in women who have never smoked: a cohort study.

COPD is responsible for an increasing number of deaths worldwide. Smoking is the most reliable predictor for developing COPD later in life. However, women make up the majority of patients with COPD who have never smoked. There is therefore a need to identify other factors that can predict COPD in women. The aim of this study is to identify factors associated with increasing the risk of developing COPD later in life in women who have never smoked. Data from the Australian Longitudinal Study on Women's Health (ALSWH) cohort born between 1946 and 1951 were used to investigate potential predictors of COPD. Retrospective analyses were performed on data from two of the ALSWH surveys: wave 1 (1996) and wave 9 (2019). There were 3584 women who self-reported as being never-smokers (at waves 1 and 9) and did not have COPD at baseline, of which 109 had developed COPD at wave 9. Logistic regression showed a significant relationship between COPD at wave 9 and baseline breathing difficulties (p<0.001), asthma (p<0.001) and allergies (p=0.026), though significance of asthma and allergies disappeared when included together in a single model, implying that women with these symptoms earlier in life were more likely to be diagnosed with COPD later in life compared to women without these symptoms. Our study supports the inclusion of lung function testing in primary care settings for women over the age of 45 years who have never smoked and have a history of breathing difficulties, asthma or allergies.

The Hypothesis of Biotensegrity and D. D. Palmer's Hypothesis on Tone: A Discussion of Their Alignment.

OBJECTIVE: The purpose of this article is to compare D. D. Palmer's hypothesis of tone with the modern hypothesis of biotensegrity. DISCUSSION: Although researchers have been using the hypothesis of biotensegrity for over 40 years to explain the mechanics of movement within biological systems, it has experienced revived support in the last 25 years. Biotensegrity as a concept is applied at the molecular, cellular, tissue, and organ levels, revealing a different understanding of the architecture of biological organisms. Biotensegrity offers a way of exploring the human body in the field of functional anatomy. The model has become popular among bodywork and movement practitioners, as it recognizes the wholeness of the human body. D. D. Palmer used tone to explain the origin of disease; biotensegrity, instead, explains why certain diseases may develop. CONCLUSION: The concept of tone hypothesized by D. D. Palmer is different from the modern concept of biotensegrity. Although biotensegrity offers a different way of seeing how the human body functions, using it as a theoretical framework to explain the effects of manual therapies such as chiropractic may be premature. The use of the biotensegrity hypothesis requires further research and investigation before application in clinical settings.

Impact of the COVID-19 Pandemic on Manual Therapy Service Utilization within the Australian Private Healthcare Setting.

The COVID-19 pandemic has impacted a wide range of health services. This study aimed to quantify the impact of the COVID-19 pandemic on manual therapy service utilization within the Australian private healthcare setting during the first half of 2020. Quarterly data regarding the number and total cost of services provided were extracted for each manual therapy profession (i.e., chiropractic, osteopathy, and physiotherapy) for the period January 2015 to June 2020 from the Australian Prudential Regulation Authority. Time series forecasting methods were used to estimate absolute and relative differences between the forecasted and observed values of service utilization. An estimated 1.3 million (13.2%) fewer manual therapy services, with a total cost of AUD 84 million, were provided within the Australian private healthcare setting during the first half of 2020. Reduction in service utilization was considerably larger in the second quarter (21.7%) than in the first quarter (5.7%), and was larger in physiotherapy (20.6%) and osteopathy (12.7%) than in chiropractic (5.2%). The impact varied across states and territories, with the largest reductions in service utilization observed in New South Wales (17.5%), Australian Capital Territory (16.3%), and Victoria (16.2%). The COVID-19 pandemic has had a profound impact on manual therapy service utilization in Australia. The magnitude of the decline in service utilization varied considerably across professions and locations. The long-term consequences of this decline in manual therapy utilization remain to be determined.

Service utilisation trends in the manual therapy professions within the Australian private healthcare setting between 2008 and 2017.

BACKGROUND: Better understanding of the dynamics and temporal changes in manual therapy service utilisation may assist with healthcare planning and resource allocation. The objectives of this study were to quantify, describe, and compare service utilisation trends in the manual therapy professions within the Australian private healthcare setting between 2008 and 2017. METHODS: Data regarding the number of services, total cost, and benefits paid were extracted for each manual therapy profession (i.e. chiropractic, osteopathy, and physiotherapy) for the period 2008-2017 from the Australian Prudential Regulation Authority. The number of registered providers for each profession were obtained from the Australian Health Practitioner Regulation Agency. Descriptive statistics were produced for two time periods (i.e. 2008-2012 and 2013-2017) for each manual therapy profession. Annual percentage change during each time period was estimated by fitting Poisson regression models. Test for the equality of regression coefficients was used to compare the trends in the two time periods within each profession, and to compare the trends across professions within a time period. RESULTS: A cumulative total of 198.6 million manual therapy services with a total cost of $12.8 billion was provided within the Australian private healthcare setting between 2008 and 2017. Although service utilisation and total cost increased throughout the ten-year period, the annual growth was significantly lower during 2013-2017 than 2008-2012. Whereas osteopathy and physiotherapy experienced significant annual growth in the number of services and total cost during 2013-2017, negative growth in the number of services was observed for chiropractic during the same period. The annual number of services per provider declined significantly for chiropractic and physiotherapy between 2013 and 2017. CONCLUSION: Service provision under private health insurance general treatment cover constitute a major source of revenue for manual therapy professions in Australia. Although manual therapy service utilisation increased throughout the ten-year period from 2008 to 2017, the annual growth declined. There were diverging trends across the three professions, including significantly greater decline in annual growth for chiropractic than for osteopathy and physiotherapy.

Prevalence and profile of Australian osteopaths treating older people.

OBJECTIVES: To explore the characteristics of the Australian osteopathy workforce who participate in the management of older patients with musculoskeletal complaints. DESIGN: Secondary analysis of a cross-sectional survey of osteopaths. SETTING: The Osteopathy Research and Innovation Network (ORION), an Australian practice-based research network. MAIN OUTCOME MEASURES: The demographic, practice and treatment characteristics of osteopaths who identify as 'always'or 'often' treating patients aged 65 years or over. RESULTS: Over half (58%) of total participants (n = 992) indicated often treating older people and this was associated with referral patterns with other health professionals and a non-urban practice location. Osteopaths providing care to older people were more likely to discuss diet/nutrition and medications, and provide pain counselling. Osteopaths who treated older adults were more likely to treat shoulder musculoskeletal disorders, degenerative spine disorders, chronic or persistent pain, and tendinopathies. CONCLUSIONS: A substantial proportion of Australian osteopaths treat older adults frequently. The potential value and impact of osteopathy in managing the health needs of an ageing population warrants close examination from both researchers and policy makers.

The effect of combining manual therapy with exercise for mild chronic obstructive pulmonary disease: study protocol for a randomised controlled trial.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of disability and hospital admission. Current management strategies have not been successful in altering the loss of lung function typically seen as the disease progresses. A recent systematic review into the use of spinal manipulative therapy (SMT) in the management of COPD concluded that there was low level evidence to support the view that a combination of SMT and exercise had the potential to improve lung function more than exercise alone in people with moderate to severe COPD. The aim of this study is to investigate whether the combination of exercise and manual therapy (MT) that includes SMT produces sustainable improvements in lung function and exercise capacity in people with mild COPD. METHODS/DESIGN: The study is a randomised controlled trial of 202 people with stable mild COPD. The cohort will be divided into two equal groups matched at baseline. The first group will receive a standardised exercise program. The second group will receive MT that includes SMT plus the same standardised exercise program. Exercise will be administered a total of 36 times over an 18-week period, while MT will be administered in conjunction with exercise a total of 15 times over a 6-week period. The primary outcome measure is lung function (forced expiratory volume in the 1st second: FEV1 and forced vital capacity: FVC). The secondary outcome measures are the 6-minute walking test (6MWT), quality of life questionnaire (St George's Respiratory Questionnaire: SGRQ), anxiety and depression levels (Hospital Anxiety and Depression Scale: HADS), frequency of exacerbations, chest wall expansion measurements (tape measurements) and systemic inflammatory biomarker levels. Outcome measurements will be taken by blinded assessors on seven occasions over a 48-week period. Adverse event data will also be gathered at the beginning of each intervention session. DISCUSSION: This randomised controlled trial is designed to investigate whether the combination of MT and exercise delivers any additional benefits to people with mild COPD compared to exercise alone. The study is designed in response to recommendations from a recent systematic review calling for more research into the effect of MT in the management of COPD.

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

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.

The immediate effect of soft tissue manual therapy intervention on lung function in severe chronic obstructive pulmonary disease.

BACKGROUND AND OBJECTIVE: In chronic obstructive pulmonary disease (COPD), accessory respiratory muscles are recruited as a compensatory adaptation to changes in respiratory mechanics. This results in shortening and overactivation of these and other muscles. Manual therapy is increasingly being investigated as a way to alleviate these changes. The aim of this study was to measure the immediate effect on lung function of a soft tissue manual therapy protocol (STMTP) designed to address changes in the accessory respiratory muscles and their associated structures in patients with severe COPD. METHODS: Twelve medically stable patients (n=12) with an existing diagnosis of severe COPD (ten: GOLD Stage III and two: GOLD Stage IV) were included. Residual volume, inspiratory capacity and oxygen saturation (SpO2) were recorded immediately before and after administration of the STMTP. A Student's t-test was used to determine the effect of the manual therapy intervention (P<0.05). RESULTS: The mean age of the patients was 62.4 years (range 46-77). Nine were male. Residual volume decreased from 4.5 to 3.9 L (P=0.002), inspiratory capacity increased from 2.0 to 2.1 L (P=0.039) and SpO2 increased from 93% to 96% (P=0.001). CONCLUSION: A single application of an STMTP appears to have the potential to produce immediate clinically meaningful improvements in lung function in patients with severe and very severe COPD.

Assignment of adverse event indexing terms in randomized clinical trials involving spinal manipulative therapy: an audit of records in MEDLINE and EMBASE databases.

BACKGROUND: Reporting of adverse events in randomized clinical trials (RCTs) is encouraged by the authors of The Consolidated Standards of Reporting Trials (CONSORT) statement. With robust methodological design and adequate reporting, RCTs have the potential to provide useful evidence on the incidence of adverse events associated with spinal manipulative therapy (SMT). During a previous investigation, it became apparent that comprehensive search strategies combining text words with indexing terms was not sufficiently sensitive for retrieving records that were known to contain reports on adverse events. The aim of this analysis was to compare the proportion of articles containing data on adverse events associated with SMT that were indexed in MEDLINE and/or EMBASE and the proportion of those that included adverse event-related words in their title or abstract. METHODS: A sample of 140 RCT articles previously identified as containing data on adverse events associated with SMT was used. Articles were checked to determine if: (1) they had been indexed with relevant terms describing adverse events in the MEDLINE and EMBASE databases; and (2) they mentioned adverse events (or any related terms) in the title or abstract. RESULTS: Of the 140 papers, 91% were MEDLINE records, 85% were EMBASE records, 81% were found in both MEDLINE and EMBASE records, and 4% were not in either database. Only 19% mentioned adverse event-related text words in the title or abstract. There was no significant difference between MEDLINE and EMBASE records in the proportion of available papers (p = 0.078). Of the 113 papers that were found in both MEDLINE and EMBASE records, only 3% had adverse event-related indexing terms assigned to them in both databases, while 81% were not assigned an adverse event-related indexing term in either database. CONCLUSIONS: While there was effective indexing of RCTs involving SMT in the MEDLINE and EMBASE databases, there was a failure of allocation of adverse event indexing terms in both databases. We recommend the development of standardized definitions and reporting tools for adverse events associated with SMT. Adequate reporting of adverse events associated with SMT will facilitate accurate indexing of these types of manuscripts in the databases.

An indication of current views of Australian general practitioners towards chiropractic and osteopathy: a cross-sectional study.

BACKGROUND: While the role of complementary medicine therapies such as chiropractic and osteopathy is yet to be clearly delineated in the Australian context, demand for these services remains high. The attitudes of general practitioners towards chiropractors and osteopaths may have played a part in producing this outcome. However, this view is based on data that were more than 10 years old. Current anecdotal evidence suggests that the previous level of support may be declining in sections of the Australian medical profession. An assessment of the current views of general practitioners towards chiropractors and osteopaths is called for. The results being reported here represent the first stage of this assessment. METHODS: This cross-sectional study was designed as a quantitative descriptive study using an anonymous online survey that included closed and open-ended questions with opportunities provided for free text. The target population was Australian general practitioners. Inclusion criteria included current medical registration, membership of the Royal Australian College of General Practitioners and currently practicing as a general practitioner in Australia. The data being reported here were collected between May and December, 2014. RESULTS: There were 630 respondents to the online survey during this period representing a response rate of 2.6 %. Results were not uniform for the two professions. More general practitioners believed chiropractic education was not evidence-based compared to osteopathic education (70 % and 50 % respectively) while scope of practice was viewed as similar for both professions. A majority of general practitioners had never referred a patient to either profession (chiropractic: 60 %; osteopathy: 66 %) with approximately two-thirds not interested in learning more about their education (chiropractors: 68 %; osteopaths: 63 %). CONCLUSIONS: This study provides an indication of the current views of Australian general practitioners towards chiropractors and osteopaths. The findings suggest that attitudes may have become less favourable with a growing intolerance towards both professions. If confirmed, this has the potential to impact health service provision. The results from this cross-sectional study suggest that obtaining representative general practitioner views using online surveys is difficult and another approach is needed to supplement or replace the current recruitment strategy.'

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

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.

Manual and Instrument Applied Cervical Manipulation for Mechanical Neck Pain: A Randomized Controlled Trial.

OBJECTIVE: The purpose of this study was to compare the effects of 2 different cervical manipulation techniques for mechanical neck pain (MNP). METHODS: Participants with MNP of at least 1 month's duration (n = 65) were randomly allocated to 3 groups: (1) stretching (control), (2) stretching plus manually applied manipulation (MAM), and (3) stretching plus instrument-applied manipulation (IAM). MAM consisted of a single high-velocity, low-amplitude cervical chiropractic manipulation, whereas IAM involved the application of a single cervical manipulation using an (Activator IV) adjusting instrument. Preintervention and postintervention measurements were taken of all outcomes measures. Pain was the primary outcome and was measured using visual analogue scale and pressure pain thresholds. Secondary outcomes included cervical range of motion, hand grip-strength, and wrist blood pressure. Follow-up subjective pain scores were obtained via telephone text message 7 days postintervention. RESULTS: Subjective pain scores decreased at 7-day follow-up in the MAM group compared with control (P = .015). Cervical rotation bilaterally (ipsilateral: P = .002; contralateral: P = .015) and lateral flexion on the contralateral side to manipulation (P = .001) increased following MAM. Hand grip-strength on the contralateral side to manipulation (P = .013) increased following IAM. No moderate or severe adverse events were reported. Mild adverse events were reported on 6 occasions (control, 4; MAM, 1; IAM, 1). CONCLUSION: This study demonstrates that a single cervical manipulation is capable of producing immediate and short-term benefits for MNP. The study also demonstrates that not all manipulative techniques have the same effect and that the differences may be mediated by neurological or biomechanical factors inherent to each technique.

Effectiveness of interventions designed to reduce the use of imaging for low-back pain: a systematic review.

BACKGROUND: Rates of imaging for low-back pain are high and are associated with increased health care costs and radiation exposure as well as potentially poorer patient outcomes. We conducted a systematic review to investigate the effectiveness of interventions aimed at reducing the use of imaging for low-back pain. METHODS: We searched MEDLINE, Embase, CINAHL and the Cochrane Central Register of Controlled Trials from the earliest records to June 23, 2014. We included randomized controlled trials, controlled clinical trials and interrupted time series studies that assessed interventions designed to reduce the use of imaging in any clinical setting, including primary, emergency and specialist care. Two independent reviewers extracted data and assessed risk of bias. We used raw data on imaging rates to calculate summary statistics. Study heterogeneity prevented meta-analysis. RESULTS: A total of 8500 records were identified through the literature search. Of the 54 potentially eligible studies reviewed in full, 7 were included in our review. Clinical decision support involving a modified referral form in a hospital setting reduced imaging by 36.8% (95% confidence interval [CI] 33.2% to 40.5%). Targeted reminders to primary care physicians of appropriate indications for imaging reduced referrals for imaging by 22.5% (95% CI 8.4% to 36.8%). Interventions that used practitioner audits and feedback, practitioner education or guideline dissemination did not significantly reduce imaging rates. Lack of power within some of the included studies resulted in lack of statistical significance despite potentially clinically important effects. INTERPRETATION: Clinical decision support in a hospital setting and targeted reminders to primary care doctors were effective interventions in reducing the use of imaging for low-back pain. These are potentially low-cost interventions that would substantially decrease medical expenditures associated with the management of low-back pain.

The provision of chiropractic, physiotherapy and osteopathic services within the Australian private health-care system: a report of recent trends.

BACKGROUND: Chiropractors, physiotherapists, and osteopaths receive training in the diagnosis and management of musculoskeletal conditions. As a result there is considerable overlap in the types of conditions that are encountered clinically by these practitioners. In Australia, the majority of benefits paid for these services come from the private sector. The purpose of this article is to quantify and describe the development in service utilization and the cost of benefits paid to users of these healthcare services by private health insurers. An exploration of the factors that may have influenced the observed trends is also presented. METHODS: A review of data from the Australian Bureau of Statistics, Australian Health Practitioner Regulation Agency, and the Australian Government Private Health Insurance Administration Council was conducted. An analysis of chiropractic, physiotherapy and osteopathic service utilisation and cost of service utilisation trend was performed along with the level of benefits and services over time. RESULTS: In 2012, the number of physiotherapists working in the private sector was 2.9 times larger than that of chiropractic, and 7.8 times that of the osteopathic profession. The total number of services provided by chiropractors, physiotherapists, and osteopaths increased steadily over the past 15 years. For the majority of this period, chiropractors provided more services than the other two professions. The average number of services provided by chiropractors was approximately two and a half times that of physiotherapists and four and a half times that of osteopaths. CONCLUSIONS: This study highlights a clear disparity in the average number of services provided by chiropractors, physiotherapists, and osteopaths in the private sector in Australia over the last 15 years. Further research is required to explain these observed differences and to determine whether a similar trend exists in patients who do not have private health insurance cover.

Short-term effects of a course of manual therapy and exercise in people with moderate chronic obstructive pulmonary disease: a preliminary clinical trial.

OBJECTIVE: The purpose of this preliminary study was to demonstrate the feasibility of a study that measures the short-term effects of a course of manual therapy (MT) and exercise (Ex) in people with moderate chronic obstructive pulmonary disease (COPD). METHODS: Fifteen participants (9 males; mean age, 56.1 years), with moderate COPD (mean % predicted forced expiratory volume in the first second [FEV1% predicted], 61.8%), were randomly allocated to 1 of 3 groups: soft tissue therapy only (ST); ST and spinal manipulation (SM); or ST, SM, and Ex. The intervention continued for 4 weeks. Outcome measures included FEV1, forced vital capacity (FVC), chronic respiratory questionnaire (CRQ-SAS) scores, distance walked in a 6-minute walking test, and monitoring for adverse events. RESULTS: There was an increase in FVC for the SM + ST + Ex group compared with ST only and ST + SM (1.01 and 1.00 L, respectively). Distance walked increased in the ST + SM and ST + SM + Ex groups compared with ST only (120.0 and 168.0 m, respectively). Dyspnea levels decreased in the ST + SM and ST + SM + Ex groups compared with ST only (0.64 and 0.44, respectively). There were no major or moderate adverse events reported following ST or SM interventions. CONCLUSIONS: For this small group of patients, combining MT with Ex produced short improvements in FVC, distance walked, and dyspnea levels, with no major or moderate adverse events. This preliminary study showed that a larger study evaluating the clinical outcomes of MT for people with moderate COPD appears feasible.

Spinal manipulative therapy for elderly patients with chronic obstructive pulmonary disease: a case series.

OBJECTIVE: The objective of this case series is to report the results of spinal manipulative therapy (SMT) for people with chronic obstructive pulmonary disease (COPD) who were older than 65 years. METHODS: The study design was a prospective case series. Six patients of a long-term care center who were older than 65 years and having COPD underwent a course of 12 SMT sessions over a 4-week period. Each SMT session consisted of manually applied spinal manipulation and instrument-assisted spinal manipulation delivered by a doctor of chiropractic. Lung function measurements were recorded at baseline and at 2 and 4 weeks. The occurrence and type of any adverse events (AEs) related to SMT were recorded at each SMT session. RESULTS: One male and 5 female patients took part in the study. The average age was 79.1 years (range, 68-89 years). There was a clinically significant increase in forced expiratory volume in the first second after SMT in 4 of the 6 patients at 2 weeks. This was sustained in only 1 patient at 4 weeks. No clinically significant changes were observed for forced vital capacity at 2 or 4 weeks. One hundred forty-four manually applied spinal manipulations and 72 instrument-assisted spinal manipulations were administered during the intervention period. No major or moderate AEs were reported. Only minor AEs were reported after 29% of the intervention sessions, with 1 AE being reported for each patient. All AEs resolved within 48 hours. CONCLUSIONS: This case series offers preliminary evidence that SMT may have the potential to benefit lung function in patients with COPD who are older than 65 years.

Progression to chronic obstructive pulmonary disease (COPD): could it be prevented by manual therapy and exercise during the 'at risk' stage (stage 0)?

A number of predisposing factors are recognised as increasing the risk of developing chronic pulmonary obstructive disease (COPD). There is increasing recognition that COPD may be an inflammatory disease with systemic consequences. However, the trigger for the transition from 'at risk' (stage 0) to COPD state remains unclear. The current approach to intervention for the 'at risk' group is risk factor avoidance. We propose that if interventions shown to improve chronic respiratory symptoms in COPD sufferers could be applied to the 'at risk' group, then moderation or even reversal of the changes typical of this transition becomes a possibility. Exercise training has been shown to be beneficial at all stages of COPD. Mobility of the chest wall influences lung function. We hypothesise that the application to 'at risk' individuals (stage 0) of therapeutic interventions known to improve chronic respiratory symptoms and cardiovascular function in mild/moderate COPD (stages 1 and 2) could delay progression of the disease (i.e. manifestation of mild/moderate COPD). If the hypothesis were confirmed, the potential to delay or even prevent the onset of COPD would be feasible.
