Delineating inflammatory and mechanical sub-types of low back pain: a pilot survey of fifty low back pain patients in a chiropractic setting

Background An instrument known as the Mechanical and Inflammatory Low Back Pain (MAIL) Scale was drafted using the results of a previous expert opinion study. A pilot survey was conducted to test the feasibility of a larger study designed to determine the MAIL Scale's ability to distinguish two potential subgroups of low back pain: inflammatory and mechanical. Methods Patients with a primary complaint of low back pain (LBP) presenting to chiropractic clinics in Perth, Western Australia were asked to fill out the MAIL Scale questionnaire. The instrument's ability to separate patients into inflammatory and mechanical subgroups of LBP was examined using the mean score of each notional subgroup as an arbitrary cut-off point. Results Data were collected from 50 patients. The MAIL Scale did not appear to separate cases of LBP into the two notionally distinct groups of inflammatory (n = 6) or mechanical (n = 5). A larger "mixed symptom" group (n = 39) was revealed. Conclusions In this pilot study the MAIL Scale was unable to clearly discriminate between what is thought to be mechanical and inflammatory LBP in 50 cases seen in a chiropractic setting. However, the small sample size means any conclusions must be viewed with caution. Further research within a larger study population may be warranted and feasible

The test-retest reliability of centre of pressure measures in bipedal static task conditions - A systematic review of the literature

Summary of background data: The analysis of centre of pressure (COP) excursions is used as an index of postural stability in standing. Conflicting data have been reported over the past 20 years regarding the reliability of COP measures and no standard procedure for COP measure use in study design has been established. Search methods: Six online databases (January 1980 to February 2009) were systematically searched followed by a manual search of retrieved papers. Results: Thirty-two papers met the inclusion criteria. The majority of the papers (26/32, 81.3%) demonstrated acceptable reliability. While COP mean velocity (mVel) demonstrated variable but generally good reliability throughout the different studies (r= 0.32-0.94), no single measurement of COP appeared significantly more reliable than the others. Regarding data acquisition duration, a minimum of 90 s is required to reach acceptable reliability for most COP parameters. This review further suggests that while eyes closed readings may show slightly higher reliability coefficients, both eyes open and closed setups allow acceptable readings under the described conditions (r≥0.75). Also averaging the results of three to five repetitions on firm surface is necessary to obtain acceptable reliability. A sampling frequency of 100. Hz with a cut-off frequency of 10. Hz is also recommended. No final conclusion regarding the feet position could be reached. Conclusions: The studies reviewed show that bipedal static COP measures may be used as a reliable tool for investigating general postural stability and balance performance under specific conditions. Recommendations for maximizing the reliability of COP data are provided

Old people - should they be eating generously, frugally or what?

The ageing of populations, associated with diminishing family size and increasing longevity, is evoking far-reaching effects on health and other services. especially in Western countries. Influencing factors in ageing include not only diet but factors such as physical activity, smoking, and alcohol consumption. There is evidence that a large proportion of morbidity in ageing is due to life-style factors. As far as diet is concerned. the question, should old people be encouraged to eat more. eat frugally, or what, largely depends on the population concerned. In prosperous countries, old people largely have enough to eat. It has been urged that their nutritional status could be improved, not so much by specific supplementation but rather by an increase in vegetable and fruit intake, with a concurrent decrease in the amount of fat consumed. The same recommendation would apply to non-Westernized elderly populations. However an adequate consumption of vegetables and fruit is often limited by cost. Databases on the minimum ranges of nutrient requirements that are consistent with good health in older populations in South Africa are required

The interrater reliability of static palpation of the thoracic spine for eliciting tenderness and stiffness to test for a manipulable lesion

Background Despite widespread use by manual therapists, there is little evidence regarding the reliability of thoracic spine static palpation to test for a manipulable lesion using stiffness or tenderness as diagnostic markers. We aimed to determine the interrater agreement of thoracic spine static palpation for segmental tenderness and stiffness and determine the effect of standardised training for examiners. The secondary aim was to explore expert consensus on the level of segmental tenderness required to locate a “manipulable lesion”. Methods Two experienced chiropractors used static palpation of thoracic vertebrae on two occasions (pragmatic and standardised approaches). Participants rated tenderness on an 11-point numerical pain rating scale (NPRS) and raters judged segmental stiffness based on their experience and perception of normal mobility with the requested outcomes of hypomobile or normal mobility. We calculated interrater agreement using percent agreement, Cohen’s Kappa coefficients (κ) and prevalence-adjusted bias-adjusted Kappa coefficients (PABAK). In a preliminary study, an expert panel of 10 chiropractors took part in a Delphi process to identify the level of meaningful segmental tenderness required to locate a “manipulable lesion”. Results Thirty-six participants (20 female) were enrolled for the reliability study on the 13th March 2017. Mean (SD) age was 22.4 (3.4) years with an equal distribution of asymptomatic (n = 17) and symptomatic (n = 17) participants. Overall, the interrater agreement for spinal segmental stiffness had Kappa values indicating less than chance agreement [κ range − 0.11, 0.53]. When adjusted for prevalence and bias, the PABAK ranged from slight to substantial agreement [0.12–0.76] with moderate or substantial agreement demonstrated at the majority of spinal levels (T1, T2 and T6 to T12). Generally, there was fair to substantial agreement for segmental tenderness [Kappa range 0.22–0.77]. Training did not significantly improve interrater agreement for stiffness or tenderness. The Delphi process indicated that an NPRS score of 2 out of 10 identified a potential “manipulable lesion”. Conclusion Static palpation was overall moderately reliable for the identification of segmental thoracic spine stiffness and tenderness, with tenderness demonstrating a higher reliability. Also, an increased agreement was found within the mid-thoracic spine. A brief training intervention failed to improve reliability

Low back pain: A major global problem for which the chiropractic profession needs to take more care

An important series of papers have been published in the Lancet. These papers provide a comprehensive update for the major global problem of low back pain, and the challenges that low back pain presents to healthcare practitioners and policy makers. Chiropractors are well placed to reduce the burden of low back pain, but not all that chiropractors do is supported by robust, contemporary evidence. This commentary summarises the Lancet articles. We also make suggestions for how the chiropractic profession should most effectively help people with low back pain by implementing practices supported by high quality evidence

How comprehensively is evidence-based practice represented in councils on chiropractic education (CCE) educational standards: A systematic audit

Background The incorporation of evidence-based practice (EBP) is widely recognised as a necessary process for entry-level health professional training. Accreditation documents reflect the practice standards of health professions. No previous study has assessed the extent to which EBP has been taken up by chiropractic regulatory/licencing authorities, known as Councils on Chiropractic Education (CCEs), around the world. The purposes of this study were to examine CCEs' educational standards for signs of a positive and negative approach to EBP as indicated by the prevalence and use of the words evidence, research, subluxation and vitalism, and to make recommendations if significant deficiencies were found. Method We undertook a systematic audit of the educational standard documents of the various CCEs. CCEs were selected on the basis of the World Health Organisation. Two investigators identified the occurrences of terms explicitly related to EBP: evidence, evidence-based, research, subluxation and vitalism. This information was tabulated for comparative purposes. The date of the study was March 2016. Results Occurrences of the term evidence, as it related to EBP, was highest in the CCE-Europe (n = 6), followed by CCE-Australia (n = 2), and CCE-USA (n = 1). None were found in the CCE-International or CCE-Canada documents. The term research appeared most frequently in the CCE-Europe documents (n = 43), followed by CCE-USA (n-32), CCE-Australia (n = 29), CCE-Canada (n = 9) and CCE-International (n = 8). The term subluxation was found only once (CCE-USA) and vitalism did not appear in any educational standard documents. Conclusions Accreditation bodies are powerfully positioned to act as a driver for education providers to give greater priority to embedding EBP into entry-level programs and shaping future directions within the profession. Terminology relating explicitly to EBP appears to be lacking in the educational standard documentation of CCEs. Therefore, future revisions of accreditation standards should address lack of terminology

Similarities and differences of a selection of key accreditation standards between chiropractic councils on education: A systematic review

Background Councils of Chiropractic Education (CCE) indirectly influence patient care and safety through their role of ensuring the standards of training delivered by chiropractic educational institutions. This is achieved by a process of accreditation where CCEs define and assess graduate competencies and educational standards. A previous study comparing CCE graduate competencies found variations between the CCE jurisdictions. It was proffered that variations in standards may potentially compromise patient care and safety and also inter-jurisdictional mutual recognition. This study continues the examination of CCEs by looking for similarities and differences in CCE accreditation standards. There were two purposes of this review. The first was to compare the accreditation standards, domains of accreditation standards, and components of the domains of accreditation standards as represented by the domains of "Mission, goals, vision, objectives", "Resources", "Faculty/Academic staff", "Educational program/curriculum". In addition, we compared the accreditation standards between CCEs and those of the widely accepted medical accreditation standards of the World Federation of Medical Education (WFME), in order to search for deficiencies and opportunities for improvements in these standards. The second purpose was to make recommendations, if significant deficiencies or variations were found. Method We undertook a systematic review of the similarities and differences between five CCEs' definitions of an accreditation standard and the descriptive lists of accreditation standards they have adopted. CCE selection criteria and data selection method were undertaken in a systematic manner. This information was tabulated for a comparative analysis and took place in April 2016. Results Only two CCEs had a definition of the term "accreditation / educational standard". At the domain level there was considerably more similarities than differences. The differences became more apparent when the comparisons were made at the component level. These included intended purposes of the mission statement, standards for faculty staff, requirements for clinical training by students, program budgetary autonomy and transparency, the inclusion of chiropractic philosophy and history, and which subjects should be taught in basic, behavioural and clinical sciences. Conclusions A series of recommendations were made. These included the need for an increased clarity of the required basic and clinical science subjects, teaching clinic student requirements, and faculty staff qualifications. These are proposed with the intention of creating uniform and high quality international accreditation standards for chiropractic education. Future research should compare the levels of CCEs inspection standards and processes to see if similarities and differences exist also there

Failure to define low back pain as a disease or an episode renders research on causality unsuitable: results of a systematic review

Background: Causative factors may be different for the very first onset of symptoms of the 'disease' of low back pain (LBP) than for ensuing episodes that occur after a pain-free period. This differentiation hinges on a life-time absence of low back pain at first onset and short-term absence for further episodes. In this systematic review, we explored whether researchers make these distinctions when investigating the causality of LBP. Methods: A literature search of PUBMED, CINAHL, and SCOPUS databases was performed from January 2010 until September 2016 using the search terms 'low back pain' or 'back pain' and 'risk factor' or 'caus*' or 'predict*' or 'onset' or 'first-time' or 'inception' or 'incidence'. Two reviewers extracted information on study design, types of episodes of back pain to distinguish the disease of LBP and recurring episodes, and also to determine the definitions of disease- or pain-free periods. Results: Thirty-three articles purporting to study causes of LBP were included. Upon scrutiny, 31 of the 33 articles were unclear as to what type of causality they were studying, that of the 'disease' or the episode, or a mere association with LBP. Only 9 studies used a prospective study design. Five studies appeared to investigate the onset of the disease of LBP, however, only one study truly captured the first incidence of LBP, which was the result of sports injury. Six appeared to study episodes but only one clearly related to the concept of episodes. Therefore, among those 11 studies, nine included both first-time LBP and episodes of LBP. Consequently, 22 studies related to the prevalence of LBP, as they probably included a mixture of first-time, recurring and ongoing episodes without distinction. Conclusion: Recent literature concerning the causality of LBP does not differentiate between the 'disease' of LBP and its recurring episodes mainly due to a lack of a clear definition of absence of LBP at baseline. Therefore, current research is not capable of providing a valid answer on this topic
