Study Design. An experimental study of respiratory function and kinematics of the diaphragm and pelvic floor in subjects with a clinical diagnosis of sacroiliac joint pain and in a comparable pain-free subject group was conducted. Objective. To gain insight into the motor control strategies of subjects with sacroiliac joint pain and the resultant effect on breathing pattern. Summary of Background Data. The active straight-leg-raise test has been proposed as a clinical test for the assessment of load transfer through the pelvis. Clinical observations show that patients with sacroiliac joint pain have suboptimal motor control strategies and alterations in respiratory function when performing low-load tasks such as an active straight leg raise. Methods. In this study, 13 participants with a clinical diagnosis of sacroiliac joint pain and 13 matched control subjects in the supine resting position were tested with the active straight leg raise and the active straight leg raise with manual compression through the ilia. Respiratory patterns were recorded using spirometry, and minute ventilation was calculated. Diaphragmatic excursion and pelvic floor descent were measured using ultrasonography. Results. The participants with sacroiliac joint pain exhibited increased minute ventilation, decreased diaphragmatic excursion, and increased pelvic floor descent, as compared with pain-free subjects. Considerable variation was observed in respiratory patterns. Enhancement of pelvis stability via manual compression through the ilia reversed these differences. Conclusions. The study findings formally identified altered motor control strategies and alterations of respiratory function in subjects with sacroiliac joint pain. The changes observed appear to represent a compensatory strategy of the neuromuscular system to enhance force closure of the pelvis where stability has been compromised by injury.

Background The Theoretical Domains Framework (TDF) is an integrative framework developed from a synthesis of psychological theories as a vehicle to help apply theoretical approaches to interventions aimed at behavior change. Purpose This study explores experiences of TDF use by professionals from multiple disciplines across diverse clinical settings. Methods Mixed methods were used to examine experiences, attitudes, and perspectives of health professionals in using the TDF in health care implementation projects. Individual interviews were conducted with ten health care professionals from six disciplines who used the TDF in implementation projects. Deductive content and thematic analysis were used. Results Three main themes and associated subthemes were identified including: 1) reasons for use of the TDF (increased confidence, broader perspective, and theoretical underpinnings); 2) challenges using the TDF (time and resources, operationalization of the TDF) and; 3) future use of the TDF. Conclusion The TDF provided a useful, flexible framework for a diverse group of health professionals working across different clinical settings for the assessment of barriers and targeting resources to influence behavior change for implementation projects. The development of practical tools and training or support is likely to aid the utility of TDF.

Objectives To determine the low back pain beliefs of Aboriginal Australians; a population previously identified as protected against the disabling effects of low back pain due to cultural beliefs. Design Qualitative study employing culturally appropriate methods within a clinical ethnographic framework. Setting One rural and two remote towns in Western Australia. Participants Thirty-two Aboriginal people with chronic low-back pain (CLBP; 21 men, 11 women). Participants included those who were highly, moderately and mildly disabled. Results Most participants held biomedical beliefs about the cause of CLBP, attributing pain to structural/anatomical vulnerability of their spine. This belief was attributed to the advice from healthcare practitioners and the results of spinal radiological imaging. Negative causal beliefs and a pessimistic future outlook were more common among those who were more disabled. Conversely, those who were less disabled held more positive beliefs that did not originate from interactions with healthcare practitioners. Conclusions Findings are consistent with research in other populations and support that disabling CLBP may be at least partly iatrogenic. This raises concerns for all populations exposed to Western biomedical approaches to examination and management of low back pain. The challenge for healthcare practitioners dealing with people with low back pain from any culture is to communicate in a way that builds positive beliefs about low back pain and its future consequences, enhancing resilience to disability.

Health indicators for rural populations in Australia continue to lag behind those of urban populations and particularly for Indigenous populations who make up a large proportion of people living in rural and remote Australia. Preparation of health practitioners who are adequately prepared to face the ‘messy swamps’ of rural health practice is a growing challenge. This paper examines the process of learning among health science students from several health disciplines from five Western Australian universities during ‘Country Week’: a one-week intensive experiential interprofessional education program in rural Western Australia. The paper weaves together strands of transformative theory of learning with findings from staff and student reflections from Country Week to explore how facilitated learning in situ can work to produce practitioners better prepared for rural health practice.

Aboriginal people in Australia have been uniquely identified as less susceptible to chronic low back pain (CLBP) disability when compared to non‐Aboriginal populations, reportedly due to cultural beliefs about pain. A qualitative, culturally secure research approach was used to explore this assumption.

&NA; • SYNOPSIS: Pain‐related fear is implicated in the transition from acute to chronic low back pain and the persistence of disabling low back pain, making it a key target for physical therapy intervention. The current understanding of pain‐related fear is that it is a psychopathological problem, whereby people who catastrophize about the meaning of pain become trapped in a vicious cycle of avoidance behavior, pain, and disability, as recognized in the fear‐avoidance model. However, there is evidence that pain‐related fear can also be seen as a common‐sense response to deal with low back pain, for example, when one is told that one’s back is vulnerable, degenerating, or damaged. In this instance, avoidance is a common‐sense response to protect a “damaged” back. While the fear‐avoidance model proposes that when someone first develops low back pain, the confrontation of normal activity in the absence of catastrophizing leads to recovery, the pathway to recovery for individuals trapped in the fear‐avoidance cycle is less clear. Understanding pain‐related fear from a common‐sense perspective enables physical therapists to offer individuals with low back pain and high fear a pathway to recovery by altering how they make sense of their pain. Drawing on a body of published work exploring the lived experience of pain‐related fear in people with low back pain, this clinical commentary illustrates how Leventhal’s common‐sense model may assist physical therapists to understand the broader sense‐making processes involved in the fear‐avoidance cycle, and how they can be altered to facilitate fear reduction by applying strategies established in the behavioral medicine literature. • KEY WORDS: common‐sense model, fear‐avoidance model, low back pain, qualitative research

Aboriginal Australians experience high rates of coronary heart disease (CHD) at an early age, highlighting the importance of effective secondary prevention. This study employed a two-stage process to evaluate CHD management in a regional Aboriginal Medical Service. Stage 1 involved an audit of 94 medical records of clients with documented CHD using the Audit and Best Practice in Chronic Disease approach to health service quality improvement. Results from the audit informed themes for focus group discussions with Aboriginal Medical Service clients (n=6) and staff (n=6) to ascertain barriers and facilitators to CHD management. The audit identified that chronic disease management was the focus of appointments more frequently than in national data (P<0.05), with brief interventions for lifestyle modification occurring at similar or greater frequency. However, referrals to follow-up support services for secondary prevention were lower (P<0.05). Focus groups identified psychosocial factors, systemic shortcomings, suboptimal medication use and variable awareness of CHD signs and symptoms as barriers to CHD management, whereas family support and culturally appropriate education promoted health care. To optimise CHD secondary prevention for Aboriginal people, health services require adequate resources to achieve best-practice systems of follow up. Routinely engaging clients is required to ensure services meet diverse community needs.

235 TO THE EDITOR: The recent guideline review by Almeida and colleagues coincides with an international call for action to address the burden of low back pain. Low back pain is a major societal problem and the number one cause of disability internationally. Recent guidelines prioritise advice, reassurance and self-management as first line care. Implementing these simple, high value interventions is important in populations, such asAboriginalAustralians,where there has been limited previous recognition of low back pain as a problem.

Objectives Undertake a systematic critical appraisal of contemporary clinical practice guidelines (CPGs) for common musculoskeletal (MSK) pain conditions: spinal (lumbar, thoracic and cervical), hip/knee (including osteoarthritis) and shoulder. Design Systematic review of CPGs (PROSPERO number: CRD42016051653). Included CPGs were written in English, developed within the last 5 years, focused on adults and described development processes. Excluded CPGs were for: traumatic MSK pain, single modalities (eg, surgery), traditional healing/medicine, specific disease processes (eg, inflammatory arthropathies) or those that required payment. Data sources and method of appraisal Four scientific databases (MEDLINE, Embase, CINAHL and Physiotherapy Evidence Database) and four guideline repositories. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument was used for critical appraisal. Results 4664 records were identified, and 34 CPGs were included. Most were for osteoarthritis (n=12) or low back pain (n=11), most commonly from the USA (n=12). The mean overall AGREE II score was 45% (SD=19.7). Lowest mean domain scores were for applicability (26%, SD=19.5) and editorial independence (33%, SD=27.5). The highest score was for scope and purpose (72%, SD=14.3). Only 8 of 34 CPGS were high quality: for osteoarthritis (n=4), low back pain (n=2), neck (n=1) and shoulder pain (n=1).

Musculoskeletal pain (MSP) conditions are the biggest cause of disability, and internationally, indigenous peoples experience a higher burden. There are conflicting reports about Aboriginal Australians and MSP. We conducted a systematic review to describe the prevalence, associated factors, impacts, care access, health care experiences, and factors associated with MSP among Aboriginal Australians.
