Efficacy of Conservative Interventions for Musculoskeletal Conditions on Pain and Disability in Active Serving Military Personnel-A Systematic Review.

INTRODUCTION: Musculoskeletal (MSK) injuries and associated pain disorders are one of the leading causes for soldiers not being medically fit for deployment, impacting force capability and readiness. Musculoskeletal pain continues to be a leading cause of disability within military services and is associated with a substantial financial burden. A better understanding of the effectiveness of MSK pain management strategies is required. This review was designed to determine the efficacy of nonsurgical interventions, such as physiotherapy, exercise, pharmacology, and multidisciplinary programs, to manage MSK conditions in active serving military populations. MATERIALS AND METHODS: MEDLINE, Embase, CINAHL, and SPORTDiscus were searched to identify relevant randomized clinical trials. Recommended methods were used for article identification, selection, and data extraction. The Cochrane Risk of Bias tool and the Grade of Recommendation, Assessment, Development, and Evaluation were used to appraise the studies. Where possible, meta-analyses were performed. The review was conducted according to the PRISMA guidelines. RESULTS: Nineteen articles (1,408 participants) met the eligibility criteria. Low back pain (LBP) was the most frequently investigated condition, followed by knee pain, neck pain, and shoulder pain. Early physiotherapy, exercise and adjunct chiropractic manipulation (for LBP), and multidisciplinary pain programs (physiotherapy, occupational therapy, and psychology) (for chronic MSK pain) improved pain (standardized mean difference ranged from -0.39 to -1.34; low strength of evidence). Participation in multidisciplinary pain programs, adjunct chiropractic manipulation, and early physiotherapy improved disability (for LBP) (standardized mean difference ranged from -0.45 to -0.86; low to very low strength of evidence). No studies evaluated pain medication. Dietary supplements (glucosamine, chondroitin sulfate, and manganese ascorbate), electrotherapy, isolated lumbar muscle exercises, home cervical traction, or training in virtual reality showed no benefit. The studies had a high risk of bias, were typically underpowered, and demonstrated high clinical heterogeneity. CONCLUSIONS: Currently available randomized clinical trials do not provide sufficient evidence to guide military organizations or health care professionals in making appropriate treatment decisions to manage MSK pain in active serving military personnel. Future research is essential to enable evidence-based recommendations for the effective management of MSK pain conditions in this unique population.

Fostering equitable change in health services: Using critical reflexivity to challenge dominant discourses in low back pain care in Australia.

OBJECTIVES: Justice and equity-focused practices in health services play a critical but overlooked role in low back pain (LBP) care. Critical reflexivity - the ability to examine and challenge power relations, and broader social issues embedded in everyday life - can be a useful tool to foster practices that are more socially just. No research has yet explored this approach in back pain health services. This study sought to understand how clinicians construct LBP in relation to broader socio-cultural-political aspects of care and explore if those constructions changed when clinicians engaged with critically reflexive dialogues with researchers. METHODS: Using critical discourse analysis methods, this qualitative study explored institutionalised patterns of knowledge in the construction of LBP care. We conducted 22 critically reflexive dialogues with 29 clinicians from two health services in Australia - a private physiotherapy clinic and a public multidisciplinary pain clinic. RESULTS: Our analyses suggested that clinicians and services often constructed LBP care at an individual level. This dominant individualistic discourse constrained consideration of justice-oriented practices in the care of people with LBP. Through dialogues, discursive constructions of LBP care expanded to incorporate systems and health service workplace practices. This expansion fostered more equitable clinical and service practices - such as assisting patients to navigate health care systems, considering patients' socioeconomic circumstances when developing treatment plans, encouraging staff discussion of possible systemic changes to enhance justice, and fostering a more inclusive workplace culture. Although such expansions faced challenges, incorporating broader discourses enabled recommendations to address LBP care inequities. CONCLUSIONS: Critical reflexivity can be a tool to foster greater social justice within health services. By expanding constructions of LBP care beyond individuals, critical reflexive dialogues can foster discussion and actions towards more equitable workplace cultures, services and systems.

'Engaging on a slightly more human level': A qualitative study exploring the care of individuals with back pain in a multidisciplinary pain clinic.

Chronic low back pain is characterised by multiple and overlapping biological, psychological, social and broader dimensions, affecting individuals' lives. Multidisciplinary pain services have been considered optimal settings to account for the multidimensionality of chronic low back pain but have largely focused on cognitive and behavioural aspects of individuals' pain. Social dimensions are usually underexplored, considered outside or beyond healthcare professionals' scope of practice. Employing Actor Network Theorist Mol's concept multiplicity, our aim in this paper is to explore how a pain service's practices bring to the fore the social dimensions of individuals living with low back pain. Drawing on 32 ethnographic observations and four group exchanges with the service's clinicians, findings suggest that practices produced multiple enactments of an individual with low back pain. Although individuals' social context was present and manifested during consultations at the pain service (first enactment: 'the person'), it was often disconnected from care and overlooked in 'treatment/management' (second enactment: 'the patient'). In contrast, certain practices at the pain service not only provided acknowledgement of, but actions towards enhancing, individuals' social contexts by adapting rules and habits, providing assistance outside the service and shifting power relations during consultations (third enactment: 'the patient-person'). We therefore argue that different practices enact different versions of an individual with low back pain in pain services, and that engagement with individuals' social contexts can be part of a service's agenda.

Patients report being satisfied with private musculoskeletal physical therapy when therapists educate effectively and facilitate shared decision making.

BACKGROUND: Overall satisfaction with physical therapy care can improve patient adherence and active involvement in their management. However, which individual factors most influence satisfaction with private practice physical therapy care is not well established. OBJECTIVE: To identify which aspects of the private practice musculoskeletal physical therapy experience best delineated "completely satisfied" and "dissatisfied patients". METHODS: The MedRisk Instrument for Measuring Patient Satisfaction with Physical Therapy Care (MRPS) was used in a cross-sectional design within 18 Australian private musculoskeletal physical therapy practices. The area under the curve (AUC) of receiver operator characteristic curves (ROC) was used to quantify the ability of the individual patient experience questions to classify the global impressions of satisfaction and likelihood to recommend to others. RESULTS: 1712 patients completed the survey (out of 7320 survey recipients - response rate 23%). High scores were identified for overall satisfaction (4.8/5 ± 0.61) and likelihood to recommend (4.78/5 ± 0.67). Individual items relating to education (AUC = 0.839 and 0.838) and shared decision making (AUC = 0.832 and 0.811) were the most accurate indicators of satisfaction and likelihood to recommend to others, respectively. CONCLUSION: Individual questionnaire items relating to education and shared decision making were the most accurate indicators of satisfaction and likelihood to recommend in patients attending private practice musculoskeletal physical therapy in Australia. Clinicians and educators should focus on developing these skills to encourage an effective therapeutic alliance and promote greater levels of patient satisfaction.

Patient experiences of referral practices and primary care physiotherapy for chronic nonspecific low back pain.

BACKGROUND: Low back pain (LBP) clinical practice guidelines recommend referral for patients with persistent LBP however discordance persists between recommended care and implementation in practice. Understanding patient experiences of referral practices and physiotherapy care could be important for optimizing LBP management in primary care settings. PURPOSE: This study explored referral experiences of people with nonspecific LBP in Australian primary care and their knowledge and experience of physiotherapy. METHODS: An interpretive descriptive qualitative framework was used with 17 participants interviewed from community-based physiotherapy practices. RESULTS: Four themes described the participants' experiences of referrals in primary care settings: 1) Referral practices ranged from formal to informal to non-existent; 2) Fragmented inter-and intra-professional LBP care management; 3) Patient perceived differences in the roles of physiotherapists and specialist physiotherapists; and 4) Patient nominated barriers and facilitators to optimal referral practices. CONCLUSION: Physiotherapists support people with LBP to improve strength and function, whereas the specialist physiotherapist's role was seen as more holistic. Referral pathways that align to clinical guideline recommendations for non-surgical management and treatment remain underdeveloped. Improved referral pathways to clinicians such as physiotherapists with additional credentialed skills and competence in musculoskeletal care could improve people's experiences of care and health outcomes.

Patient perspectives of care pathways for people with low back pain: A qualitative study.

BACKGROUND: Low back pain (LBP) care pathways aim to enhance health outcomes through patient-clinician mutual decision-making and care coordination. However, challenges to successful translation into practice include patients' understanding, expectation, and acceptance of treatment and management strategies for LBP. This study explored patients' perspectives and/or experience of care pathways and their involvement in decision-making in primary care. METHODS: A qualitative descriptive design was adopted. Semi-structured interviews were conducted with 14 participants with LBP recruited from the community. Inductive thematic analysis of the qualitative data was conducted within the design framework to enable a systematic comparison of experiences across participants and within individual cases. RESULTS: Five themes described participant perspectives and understanding of care pathways: i) care pathways can guide decision-making; ii) familiarity with no and/or stepped care pathway, but preference for matched or blend of care pathways; iii) engaging in shared decision-making; iv) patient-related barriers to implementation; v) patient-related facilitators to implementation. CONCLUSIONS: Participants felt that existing care pathways did not meet their needs when pain persisted. Participants preferred matched or hybrid care pathways and suggested that implementation of such pathways should focus on addressing an individual's needs. Adopting a holistic approach, and clarity in shared decision-making, were deemed crucial for effective implementation of LBP pathways in practice. Consumer (patient) engagement in the design of LBP care pathways is recommended.

The first year of private practice - new graduate physiotherapists are highly engaged and satisfied but edging toward burnout.

BACKGROUND: A greater understanding of physiotherapists' work-life during their first year of work in private practice, and whether their experiences are mediated by personal traits, may provide valuable information to support their transition and retention. OBJECTIVES: Describe the first year of practice for graduate physiotherapists in terms of employee engagement, job satisfaction, performance, and burnout, and evaluate the relationship between these measures and personal traits (resilience, grit, mind-set). DESIGN: One-year longitudinal mixed-methods study. METHODS: Twenty new graduate physiotherapists completed questionnaires evaluating resilience, grit, and mind-set within 1-week of commencing employment. Engagement and job satisfaction were evaluated at 3, 6 and 12-months, and burnout evaluated at 12-months. Performance data (number of patients seen, revenue) were collected throughout the year. Individual semi-structured interviews were conducted at baseline, 3, 9 and 12-months. RESULTS: Engagement and satisfaction were high at all time points. At 12-months, burnout was at a medium level. Resilience was positively associated with job satisfaction at 6 (ρ = 0.56, p = .019) and 12-months (ρ = 0.54, p = .027). Engagement (ρ = -0.57, p = .04) and job satisfaction (ρ = -0.56, p = .03) were negatively associated with burnout at 12-months. All participants remained passionate about their work although increasing administrative burden and patient complexity contributed to feelings of burnout. CONCLUSIONS: Resilience was positively associated with job satisfaction suggesting those with capacity to 'bounce back' were more satisfied and engaged with their job. Although moderate levels of burnout were reported at 12-months, those with higher job satisfaction and employee engagement had lower levels of burnout. Participants proposed practical strategies to help mitigate burnout.

Evaluation of the vestibular/ocular motor screening assessment in active combat sport athletes: an exploratory study.

OBJECTIVE: The first aim of this study was to compare the results of the vestibular/ocular motor screening (VOMS) in combat sport athletes with a healthy control population. Second, to explore differences between athletes with and without a concussion history. Third, to examine the relationship between VOMS and the Post-Concussion Symptom Scale (PCSS) in combat sport athletes. PARTICIPANTS: Forty active male combat sport athletes and 40 healthy male control participants were recruited from 4 clubs and a University in Australia. METHODS: Participants completed the VOMS in a primary care physiotherapy clinic. Participants completed an injury questionnaire and the PCSS. RESULTS: An "abnormal" score in at least one subtest or near point convergence (NPC) was recorded in 45% of the combat group compared with 22.5% of the control group. All VOMS scores and NPC distance were greater in the combat group compared with control group (p < 0.05). The VOMS scores were found to be moderately positively correlated with the PCSS. There was no difference in VOMS between athletes with and without a history of concussion (p > 0.05). CONCLUSION: VOMS scores differed between combat sport athletes and control participants. The PCSS may aid clinicians in identifying athletes who have underlying vestibular/oculomotor impairment.

Cervical spine characteristics differ in competitive combat athletes compared with active control participants.

BACKGROUND: Injury to the head and neck are common in combat sport athletes. Impairments of the cervical spine have been found in some athletes who participate in sports with high forces and collisions. There is a lack of research on the effects of combat sports on the cervical spine. OBJECTIVE: The primary study aim was to investigate differences in cervical spine characteristics between combat athletes and a similarly aged active control group. The secondary aim was to investigate the relationship between symptom-based outcome measures and characteristics of the cervical spine. DESIGN: Cross-sectional. METHOD: 40 male adult combat sport athletes and 40 male adult control participants were recruited from 4 combat sport clubs and a university campus, Australia. Cervical spine assessments were conducted at a private physiotherapy clinic. The Neck Disability Index and the Post-Concussion Symptom Scale were used as symptom-based outcome measures. RESULTS: Combat sport athletes had a reduced range of cervical motion, but greater isometric strength and endurance compared with a control group (p < 0.05). The Neck Disability Index and Post-Concussion Symptom Scale were negatively correlated with cervical spine range of motion and isometric strength, meaning that higher scores correlated with a reduction in function. CONCLUSIONS: Differences were observed in characteristics of the cervical spine in combat sport athletes compared with a control group. Higher symptom-based outcome scores correlated with reduced range of motion and strength of cervical spine muscles. Further investigation to establish clinical cut-off scores for functional impairment may be warranted.

Vestibular and oculomotor function in male combat sport athletes.

OBJECTIVES: To investigate for differences in vestibulo-ocular function between active male combat sport athletes and a healthy control group. In addition, to explore the relationship between symptom-based outcome measures with vestibulo-ocular function. DESIGN: Cross-sectional. METHODS: 40 male adult combat sport athletes and 40 active male control participants were recruited from 4 martial arts schools and a University campus in Queensland, Australia. All participants completed a standardised protocol which was used to assess vestibulo-ocular function. The protocol included 3 components: 1) oculomotor function, 2) benign paroxysmal positional vertigo screening, and 3) vestibulo-ocular reflex function. The Post-Concussion Symptom Scale, Vestibular/Ocular Motor Screening tool and Dizziness Handicap Inventory were used as symptom-based outcome measures. RESULTS: More combat sport athletes had oculomotor abnormalities than control group participants. There were no between group differences in benign paroxysmal positional vertigo, vestibulo-ocular reflex function and the video-head impulse test gain (ms). Combat sport athletes had higher symptom-based outcome scores. The Vestibular/Ocular Motor Screening tool and Dizziness Handicap Inventory were found to have moderate positive relationships with the total number of abnormalities detected in the combat sport group. CONCLUSIONS: Vestibulo-ocular function is imperative for combat sport athletes to perform evasive manoeuvres and land their own strikes. The present study findings may aid clinicians in the identification of combat sport athletes with underlying vestibulo-ocular dysfunction, prompting further investigation.

Physiotherapists Both Reproduce and Resist Biomedical Dominance when Working With People With Low Back Pain: A Qualitative Study Towards New Praxis.

Despite recommendations to incorporate physical and psychosocial factors when providing care for people with back pain, research suggests that physiotherapists continue to focus on biological aspects. This study investigated how interpersonal and institutional norms influence this continued enactment of the biological aspects of management. We used theoretically-driven analysis, drawing from Foucauldian notions of power, to analyse 28 ethnographic observations of consultations and seven group discussions with physiotherapists. Analysis suggested that physiotherapy training established expectations of what a physiotherapist 'should' focus on, and institutional circumstances strongly drew the attention of physiotherapists towards biological aspects. Resistance to these forces was possible when, for example, physiotherapists reflected upon their practice, used silences and pauses during consultations, and actively collaborated with patients. These circumstances facilitated use of non-biomedical management approaches. Findings may assist physiotherapists to rework the enduring normative focus on biomedical aspects of care when providing care for patients with back pain.

Investigating the effects of mobilization with movement and exercise on pain modulation processes in shoulder pain - a single cohort pilot study with short-term follow up.

OBJECTIVE: To explore the association between manual therapy and exercise and pain modulation and clinical characteristics in people with musculoskeletal shoulder pain. METHODS: This is a prospective, longitudinal, single cohort pilot study. People with shoulder pain for longer than 6 weeks underwent 4 weeks of glenohumeral mobilization with movement and shoulder exercises. Measures of pain modulation, shoulder pain, disability, range of motion and psychosocial factors were assessed at baseline and immediately after the 4-week period of treatment. Treatment effectiveness was assessed through parametric, non-parametric and multilevel modeling statistics. RESULTS: Twenty-three individuals participatedwith no loss to follow-up. Significant and meaningful improvements in shoulder pain (NRS mean change 1.6/10, 95% CI 0.4 to 2.7), disability (SPADI mean change 20.5/100, 95% CI 13.1 to 27.9) and range of motion (mean change 33°, 95% CI 23 to 43°) were observed following treatment. Statistical but non-clinically meaningful changes were observed in temporal summation of pain (mean change 0.3/10, 95% CI 0.1 to 0.4) and anxiety (mean change 0.86/21, 95% CI 0.18 to 1.55). Significant reductions were observed in temporal summation of pain (mean change 0.3/10, 95% CI 0.1 to 0.4) and anxiety (mean change 0.86/21, 95% CI 0.18 to 1.55), however these were not considered clinically important. No association was found between clinical characteristics and sensory measures. No association was found between clinical characteristics and sensory measures. CONCLUSION: Glenohumeral mobilization with movement and exercise did not improve pain modulation, despite improvements in pain, function and range of motion, in people with shoulder pain.

Impact of an interactive workshop on specialist physiotherapists' practice when implementing a new clinical care pathway for people with musculoskeletal conditions.

BACKGROUND: A new pathway of care proposes early comprehensive assessment and targeted management by specialist musculoskeletal clinicians for people with musculoskeletal conditions at risk of poor outcomes. Adoption of this care pathway is likely to be influenced by beliefs and behaviours of specialist musculoskeletal clinicians. OBJECTIVE: To evaluate the effect of an interactive educational workshop about the proposed clinical care pathway on knowledge, beliefs and practice of specialist musculoskeletal physiotherapists. DESIGN: Mixed methods. METHODS: Fifty specialist musculoskeletal physiotherapists participated in a 2-day interactive educational workshop. Knowledge, beliefs and clinical practice behaviours were assessed immediately before the workshop and 3 months' later using surveys. RESULTS: Knowledge about key guideline messages improved and were maintained at follow-up. Most participants agreed to provide more targeted interventions to patients at risk of poor outcome (92%, 95% CI: 81%-98%) and utilise prognostic screening tools (84%, 95% CI: 71 to 93). However, only 56% (95% CI: 39%-68%) of participants believed implementing a shared care pathway was easy. At follow-up, participants' beliefs were more aligned with the proposed care pathway (i.e., shared care: 83%, 95% CI: 68%-93%). With respect to clinical practice, there were 16% more referrals back to the primary physiotherapist at 3 months than before the workshop. Barriers (practitioner, patient and system factors) to implementation of the care pathway were discussed. CONCLUSION: An interactive educational workshop influenced specialist musculoskeletal physiotherapists' knowledge, beliefs and clinical practice, but barriers need to be overcome to facilitate widespread implementation.

Localised manual therapy treatment has a preferential effect on the kinematics of the targeted motion segment.

AIM: An observational cohort study to determine whether localised manual therapy results in a preferential increase in mobility of the targeted motion segment. METHOD: Eighteen participants with mechanical neck pain had three MRIs of their cervical spine. The first two were taken prior to treatment in neutral and at the end of active rotation in their more limited rotation. Participants received localised manual therapy targeting a motion segment deemed to be relevant to their presentation until either their range increased by > 10° or 8 min, whichever came first. A third MRI was performed immediately after treatment with their head in the same rotated position as pre-treatment. In the images, each vertebra was segmented using a semi-automated process. Movement between neutral and rotated positions was calculated as Euler angles and distance of facet translations for each motion segment. RESULTS: Rotation and lateral flexion at the targeted location increased by 40% (mean 0.86° (CI: 0.24-1.48) and 15% (mean 0.52° (CI: 0.17-1.21) respectively with only the CIs for rotation not containing zero. The mean changes for the non-targeted locations were less than 0.1° for each axis and all CIs contained zero. Facet translations at the targeted location increased by 25% (0.419 mm) and decreased by >4% (>0.01 mm) at the untreated locations but the wide CIs both contained zero. CONCLUSION: Localised manual therapy seems to have a preferential effect on mobility of the targeted motion segment. The findings support considering segmental dysfunction in clinical reasoning and the use of specifically targeted manual therapy interventions.

The association of concussion history and symptom presentation in combat sport athletes.

OBJECTIVE: The purpose of this study was to describe the concussion-related symptoms reported among combat sport athletes with and without a history of concussion, and a history of neck injury. DESIGN: Cross-sectional survey. SETTING: Data were collected using an online survey instrument. PARTICIPANTS: Three hundred and nine adult combat sport athletes. MAIN OUTCOME MEASURES: Self-reported 12-month concussion history and neck injury history and a 22-item symptom checklist. RESULTS: A history of concussion was reported by 19.1% of athletes, a history of neck injury was reported by 23.0%, and 13.6% reported both injuries. Neck pain was the most frequently reported symptom. Athletes with a history of injury had significantly greater proportions of 'high' total symptoms and symptom severity scores compared with athletes with no history of injury. Athletes with a history of concussion had 2.35 times higher odds of reporting 'high' total symptoms and symptoms severity scores. CONCLUSION: Athletes with a history of concussion or neck injury have greater odds of presenting with higher symptom scores. The presence of high total symptom scores and high symptom severity scores may indicate a need for further investigation into domains commonly associated with concussion.

Implementation of a novel stratified PAthway of CarE for common musculoskeletal (MSK) conditions in primary care: protocol for a multicentre pragmatic randomised controlled trial (the PACE MSK trial).

INTRODUCTION: Musculoskeletal (MSK) conditions constitute the highest burden of disease globally, with healthcare services often utilised inappropriately and overburdened. The aim of this trial is to evaluate the effectiveness of a novel clinical PAthway of CarE programme (PACE programme), where care is provided based on people's risk of poor outcome. METHODS AND ANALYSIS: Multicentre randomised controlled trial. 716 people with MSK conditions (low back pain, neck pain or knee osteoarthritis) will be recruited in primary care. They will be stratified for risk of a poor outcome (low risk/high risk) using the Short Form Örebro Musculoskeletal Pain Screening Questionnaire (SF-ÖMSPQ) then randomised to usual care (n=358) or the PACE programme (n=358). Participants at low risk in the PACE programme will receive up to 3 sessions of guideline based care from their primary healthcare professional (HCP) supported by a custom designed website (mypainhub.com). Those at high risk will be referred to an allied health MSK specialist who will conduct a comprehensive patient-centred assessment then liaise with the primary HCP to determine further care. Primary outcome (SF 12-item PCS) and secondary outcomes (eg, pain self-efficacy, psychological health) will be collected at baseline, 3, 6 and 12 months. Cost-effectiveness will be measured as cost per quality-adjusted life-year gained. Health economic analysis will include direct and indirect costs. Analyses will be conducted on an intention-to-treat basis. Primary and secondary outcomes will be analysed independently, using generalised linear models. Qualitative and mixed-methods studies embedded within the trial will evaluate patient experience, health professional practice and interprofessional collaboration. ETHICS AND DISSEMINATION: Ethics approval has been received from the following Human Research Ethics Committees: The University of Sydney (2018/926), The University of Queensland (2019000700/2018/926), University of Melbourne (1954239), Curtin University (HRE2019-0263) and Northern Sydney Local Health District (2019/ETH03632). Dissemination of findings will occur via peer-reviewed publications, conference presentations and social media. TRIAL REGISTRATION NUMBER: ACTRN12619000871145.

Reduced shoulder strength and change in range of motion are risk factors for shoulder injury in water polo players.

OBJECTIVE: To determine whether pre-season shoulder ROM and strength can be used to identify athletes at risk of future shoulder injury. DESIGN: Prospective cohort. SETTING: High performance sports institute. PARTICIPANTS: 76 sub-elite water polo players. MAIN OUTCOME MEASURES: Mean pre-season shoulder internal (IR) and external rotation (ER) ROM and strength values compared by gender, dominance and prospective injury status. RESULTS: 14-dominant shoulder injuries were recorded. There was a significant difference (p = 0.05) in total ROM difference (TROM) between the prospectively injured and no injury groups (-17.2°(30.4);-0.8°(13.3)), and dominant side ER strength (11.7%(2.4) vs 14.5%(2.8), p = 0.03) and IR strength (16.5%(3.0) vs 21.6%(4.9) as a percentage body weight (PBW) were also significantly different (p ≤ 0.03). Separate significant associations were found between future episodes of shoulder injury and; dominant shoulder TROM difference of ≥7.5°(OR 3.6,95%CI 0.8-16.0), ER strength as a PBW≤12.5%(OR 5.2,95%CI 1.0-27.9), and IR strength as a PBW≤16.8%(OR 13.8,95%CI 2.2-88.0). CONCLUSION: Pre-season dominant TROM difference, and reduced shoulder IR and ER strength relative to body weight were significant predictors for future shoulder injury. Although further investigation with a larger sample size is required, achieving optimal values on these measures may reduce future episodes of shoulder injury in water polo players.

Concussion in Combination With Whiplash-Associated Disorder May Be Missed in Primary Care: Key Recommendations for Assessment and Management.

SYNOPSIS: Whiplash and concussion may have similar presenting symptoms, biomechanical mechanisms, and neurophysiological sequelae, but neither enjoys a gold standard diagnostic test. Guidelines for whiplash and concussion are developed and implemented separately. This disparate process may contribute to misdiagnosis, delay appropriate primary care management, and impair patient outcomes. In our clinical commentary, we present 3 cases where signs and symptoms consistent with whiplash were identified in primary care. Symptoms in all cases included neck pain, headache, dizziness, and concentration deficits, raising suspicion of coexisting postconcussion syndrome. All cases were referred for specialist physical therapy. Characteristics consistent with poor recovery in both whiplash and postconcussion syndrome were confirmed, and multidisciplinary management, drawing from both whiplash and concussion guidelines, was implemented. All patients reported improvement in activities of daily living after tailored management addressing both neck and head injury-related factors, suggesting that these conditions were not mutually exclusive. Self-reported outcomes included reductions in neck disability and postconcussion symptoms of between 20% and 40%. It may be appropriate for whiplash and concussion guidelines to be amalgamated, enhanced, and mutually recognized on a patient-by-patient basis. Primary health care professionals might consider minimum screening to identify postconcussion syndrome in patients following motor vehicle collision by administering questionnaires and assessing cranial nerve function, balance, and cognition. Management should then incorporate principles from both whiplash and concussion guidelines and harmonize with available imaging guidelines for suspected spine and head trauma.

Identifying psychosocial characteristics that predict outcome to the UPLIFT programme for people with persistent back pain: protocol for a prospective cohort study.

INTRODUCTION: Prognostic screening of people with low back pain (LBP) improves utilisation of primary healthcare resources. Whether this also applies to secondary healthcare remains unclear. Therefore, this study aims to develop prognostic models to determine at baseline which patients with persistent LBP are likely to have a good and poor outcome to a 5-week programme of combined education and exercise ('UPLIFT') delivered in a secondary healthcare setting. METHODS AND ANALYSIS: A prospective cohort study of 246 people with persistent LBP will be conducted in a secondary healthcare outpatient setting. Patients will be recruited from a physiotherapy-led neurosurgical screening clinic. Demographic data, medical history and psychosocial characteristics will be recorded at baseline. Fear avoidance beliefs, pain self-efficacy, LBP treatment beliefs, pain catastrophising, perceived injustice, depression, anxiety and stress, disability level, pain intensity and interference, health status and social connectedness will be considered as potential prognostic variables, which will be assessed using self-reported questionnaires. Participants will attend the UPLIFT programme, consisting of weekly 90 min group sessions that combine interactive education sessions and a graded exercise programme. The outcome measure to identify good and poor outcome is the Global Rating of Change scale, assessed at completion of the UPLIFT programme and at 6 months follow-up. Multiple imputation analyses will be performed for missing values. Prognostic models will be developed using multivariable logistic regression analyses, with bootstrapping techniques for internal validation. We will calculate the explained variance of the models and the area under the receiver operating characteristic curve. Furthermore, we will determine whether participation in the UPLIFT programme is associated with changes in psychosocial characteristics. ETHICS AND DISSEMINATION: Gold Coast Health Service Human Research Ethics Committee (HREC/18/QGC/41) and the Griffith University Human Research Ethics Committee (GU Ref No: 2018/408) approved the study. Dissemination of findings will occur via peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: ACTRN12618001525279.

Measurement of three-dimensional cervical segmental kinematics: Reliability of whole vertebrae and facet-based approaches.

BACKGROUND: Previous studies have used orientation and translation of whole-vertebrae to describe three-dimensional cervical segmental kinematics. Describing kinematics using facet joint movement may be more relevant to pathology and effects of interventions but has not been investigated in the cervical spine. This study compared the reliability of two different methods (whole-vertebrae vs facet joint) to evaluate cervical kinematics. METHODS: Two healthy adults each had six cervical (C1 to T1) magnetic resonance imaging scans, two each in neutral and left and right rotation. A semi-automated method of segmentation and alignment determined the relative orientation and translation of each whole-vertebrae and translation of each facet joint. Intra-rater and inter-rater reliability was determined using limits of agreement (LOA) with 95% confidence intervals and intraclass correlation coefficients (ICC3,1 for intra- and ICC2,1 for inter-rater). RESULTS: The LOA for intra-rater evaluation of facet movement was superior to whole vertebra translation. Both methods showed excellent intra-rater ICC3,1 (0.80-0.99) and inter-rater ICC2,1 (0.79-0.85) for all variables except for Euler angle for flexion/extension which was good (0.65). Intra-and inter-rater ICCs were better for facet movement than all measures of whole of vertebrae movement except Euler angles of axial rotation where no difference was detected. CONCLUSIONS: Measurement of three-dimensional segmental kinematics using either the facet joint or the whole-vertebrae method demonstrated excellent and comparable reliability. These findings support the use of the facet joint method as an option for describing and investigating cervical segmental kinematics.
