Neck or Shoulder? Establishing Consensus for Spine Screening in Patients with Shoulder Pain: an International Modified Delphi Study.

OBJECTIVE: There is no established consensus for screening the spine in patients with shoulder pain. The aim of this study was to explore the role of the spine in shoulder pain and generate a set of recommendations for assessing the potential involvement of the spine in patients with shoulder pain. METHODS: A modified Delphi study was conducted through use of an international shoulder physical therapist's expert panel. Three domains (clinical reasoning, history, physical examination) were evaluated using a Likert scale, with consensus defined as Aiken Validity Index ≥0.7. RESULTS: Twenty-two physical therapists participated. Consensus was reached on a total of 30 items: clinical reasoning (n = 9), history (n = 13), and physical examination (n = 8). The statement that spinal and shoulder disorders can coexist, sometimes influencing each other and at other times remaining independent issues, along with the concept of radiating pain as an explanatory phenomenon for the spine contribution to shoulder pain, achieved the highest degree of consensus. CONCLUSION: International physical therapists shoulder experts reached consensus on key aspects when screening the spine in people with shoulder pain, including consideration of the distal location of symptoms relative to the shoulder, the presence or previous history of neck pain, the changes in symptoms related to neck movements, and the presence of neuropathic-like symptoms. They also acknowledged the importance of assessing active cervical or cervicothoracic movements and the usefulness of the Spurling test and symptom modification techniques applied to the spine.

Mental health of veterinary nurses and student veterinary nurses: A scoping review.

BACKGROUND: Research has shown that veterinarians around the world are at high risk of mental health problems, but far less research has examined the mental health of veterinary nurses (VNs) and student veterinary nurses (SVNs). This scoping review aimed to map existing evidence on this topic and identify knowledge gaps. METHODS: Literature searches of MEDLINE, PsycINFO, PubMed, Web of Science and Google Scholar were conducted, and a structured screening and selection procedure was applied. To be included, studies had to be peer reviewed, report relevant results specific to VNs and/or SVNs, and provide descriptive statistics if using quantitative methods. RESULTS: Of the 2118 publications identified, only 13 journal articles met the inclusion criteria. The findings were summarised in five categories: mental health and wellbeing, burnout, stress, compassion fatigue and moral distress. While the findings of five of the studies suggested that some VNs and SVNs experienced some form of poor mental health, these studies lacked generalisability or transferability for multiple reasons. There was also inconsistency and ambiguity in the interpretation of findings, as well as incompatible or oversimplified definitions of mental health problems. LIMITATIONS: Our review excluded grey literature, such as reports, theses and conference presentations, as a preliminary search found very little empirical research on VNs' and SVNs' mental health in this type of publication. CONCLUSIONS: More research is needed to address the gaps in the existing evidence supporting our understanding of VN and SVN mental health. This should establish baseline measures and include comparisons with other occupational and national populations.

Effects of matched vs. unmatched physical therapy interventions on pain or disability in patients with neck pain - a systematic review and meta-analysis.

BACKGROUND: The interventions performed in most randomized controlled trials (RCTs) on neck pain patients are standardized, irrespective of the high heterogeneity of patients. However, clinicians tend to choose an intervention based on the patients' clinical characteristics, and thus match the treatment to the patient. OBJECTIVES: To investigate the effectiveness of interventions matched to the clinical characteristics of patients with neck pain versus the same, but unmatched treatment for improving pain or disability. DESIGN: A systematic review and meta-analysis conducted following Cochrane guidelines. METHODS: Databases searches were performed from inception to September 2023. RCTs were included if the patients in the experimental group received a treatment matched to clinical presentation or to clinicians' assessment, if the patients in the control group received a similar but unmatched treatment, and if pain or disability were reported as outcome measures. RESULTS: The literature search produced 9516 records of which 27 met the inclusion criteria. Matched exercise therapy was superior to unmatched exercise for pain (SMD -0.57; 95% CI -0.95, -0.18) and for disability (SMD -0.69; 95% CI -1.14, -0.23) at short term, but not at intermediate-term follow-up. Matched manual treatment was not superior to unmatched manual therapy for pain or for disability at short or intermediate-term follow-up. CONCLUSIONS: Results suggest that matching exercise to movement limitation, trapezius myalgia, or forward head position may lead to better outcomes in the short term, but not in the intermediate-term. Matched manual therapy was not superior to unmatched treatment either short or intermediate-term. Further research is warranted to verify if those criteria are potentially useful matching criteria.

Response to the Letter to the Editor-in-Chief Regarding the Paper "The Benefits of Adding Manual Therapy to Exercise Therapy for Improving Pain and Function in Patients with Knee or Hip Osteoarthritis: A Systematic Review with Meta-Analysis".

Author response to the JOSPT Letter to the Editor-in-Chief "Leveraging the short-term benefits of manual therapy which includes exercise over exercise therapy alone appears justified for knee osteoarthritis" J Orthop Sports Phys Ther 2023;53(1):50-51. doi:10.2519/jospt.2023.0201-R.

KCTD1 and Scalp-Ear-Nipple ('Finlay-Marks') syndrome may be associated with myopia and Thin basement membrane nephropathy through an effect on the collagen IV α3 and α4 chains.

INTRODUCTION: Scalp-Ear-Nipple syndrome is caused by pathogenic KCTD1 variants and characterised by a scalp defect, prominent ears, and rudimentary breasts. We describe here further clinical associations in the eye and kidney. METHODS: Fifteen affected members from two unrelated families with p.(Ala30Glu) or p.(Pro31Leu) in KCTD1 were examined for ocular and renal abnormalities. The relevant proteins were studied in the eye and kidney, and the mutation consequences determined from mouse knockout models. RESULTS: Five males and 10 females with a median age of 40 years (range 1-70) with pathogenic variants p.(Ala30Glu) (n = 12) or p.(Pro31Leu) (n = 3) in KCTD1 were studied. Of the 6 who underwent detailed ophthalmic examination, 5 (83%) had low myopic astigmatism, the mean spherical equivalent of 10 eyes was 2.38D, and one (17%) had hypermetropic astigmatism. One female had a divergent strabismus.Five individuals had renal cysts (5/15, 33%), with renal biopsy in one demonstrating a thinned glomerular basement membrane identical to that seen in Thin basement membrane nephropathy (AD Alport syndrome).In the eye, KCTD1 and its downstream targets, TFAP2, and the collagen IV α3 and α4 chains localised to the cornea and near the retinal amacrine cells. In the kidney, all these proteins except TFAP2 were expressed in the podocytes and distal tubules. TFAP2B and COL4A4 knockout mice also had kidney cysts, and COL4A3 and COL4A4 knockout mice had myopia. CONCLUSION: Individuals with a pathogenic KCTD1 variant may have low myopic astigmatism and represent a further rare genetic cause for a thinned glomerular basement membrane.

Increased seizure frequency in an epilepsy patient receiving medium cut-off dialysis.

This paper presents the case of a male dialysis patient, with generalised epilepsy, who experienced complications after starting medium cut-off (MCO) dialysis. While receiving haemodiafiltration, the patient's epilepsy had been relatively well controlled using two antiseizure medications (brivaracetam and sodium valproate). However, the patient's seizure frequency increased when he was changed to MCO dialysis. MCO is a new dialysis method that has been developed to allow for better clearance of uraemic toxins through its larger pore size. We hypothesise that using the highly permeable MCO membrane changed the seizure threshold by an unknown mechanism. This is the first reported case to observe increased seizure frequency in a patient receiving MCO dialysis. The case highlights the need for caution when prescribing dialysis methods to patients with epilepsy.

The Benefits of Adding Manual Therapy to Exercise Therapy for Improving Pain and Function in Patients With Knee or Hip Osteoarthritis: A Systematic Review With Meta-analysis.

OBJECTIVE: To evaluate if there was an additional benefit of combining manual therapy (MT) and exercise therapy over exercise therapy alone on pain and function in patients with hip or knee osteoarthritis. DESIGN: Intervention systematic review LITERATURE SEARCH: We (1) searched 4 databases from inception to June 20, 2021; (2) hand searched a reference list of included trials and relevant systematic reviews; and (3) contacted 2 researchers in the field. STUDY SELECTION CRITERIA: We included randomized controlled trials that compared MT and exercise therapy to similar exercise therapy programs alone in patients with hip or knee osteoarthritis. DATA SYNTHESIS: The data were combined using random-effects meta-analyses where appropriate. The certainty of evidence for each outcome was judged using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. RESULTS: We included 19 trials. There was very low to moderate certainty of evidence that MT added benefit in the short term for pain, and combined pain, function, and stiffness (WOMAC global scale), but not for performance-based function and self-reported function. In the medium term, there was low- to very-low-certainty evidence that MT added benefit for performance-based function and WOMAC global score, but not for pain. There was high-certainty evidence that MT provided no added benefit in the long term for pain and function. CONCLUSION: There was very low to moderate certainty of evidence supporting MT as an adjunct to exercise therapy for pain and WOMAC global scale, but not function in patients with knee or hip osteoarthritis in the short term. There was high certainty of evidence of no benefit for additional MT over exercise therapy alone in the long term. J Orthop Sports Phys Ther 2022;52(10):675-684.

Expert visual assessment strategies for equine lameness examinations in a straight line and circle: A mixed methods study using eye tracking.

BACKGROUND: A large number of lameness indicators have been suggested for the visual equine lameness assessment. However, it remains unknown which of these are commonly used by experts. METHODS: Twenty-four expert lameness assessors from 10 leading UK institutions viewed 28 video clips of sound and mildly lame horses (median score 2/10). Horses were shown at trot in a straight line (rear and front view) and circle (side view, left and right rein). Eye tracking data were collected at 60 Hz while participants evaluated each clip. A questionnaire captured contextual information. RESULTS: During assessment on the straight line, participants consistently looked mostly at the head and pelvis. On the circle, many participants consistently looked at the head, yet the subsequent choice, weighting and order of examined body regions was unsystematic between and within participants, and there was a bias towards prolonged assessment of the horse's front region. Questionnaires revealed different descriptions of lameness indicators for the same body region and different approaches to decision making under uncertainty. CONCLUSION: In contrast to reasonably high similarity on the straight line, expert veterinarians have not developed a consistent assessment approach when evaluating horses on the circle. The reliability of various lameness indicators on the circle requires a stronger evidence base for a more systematic, repeatable approach.

Robustness of five different visual assessment methods for the evaluation of hindlimb lameness based on tubera coxarum movement in horses at the trot on a straight line.

BACKGROUND: The evaluation of hindlimb lameness remains a major challenge in everyday clinical practice. In the absence of clear guidelines, veterinarians use different visual assessment methods for this task whose robustness is unknown. OBJECTIVES: Determination of the robustness of five visual hindlimb lameness assessment methods based on the comparison of left and right tuber coxae movement. STUDY DESIGN: Validated mathematical hindlimb lameness model based on experimental data from the literature. METHODS: Vertical movement of left (LTC) and right (RTC) tuber coxae was simulated for the range of common hindlimb lameness movement patterns that horses present within practice. Lameness severity ranged from sound to moderately lame (0% to 60% motion asymmetry). The scenarios of a pelvis held tilted and asymmetrical pelvic roll were included to reflect possible adaptations in pelvic rotation. Across all conditions, the outcomes for five different visual assessment methods based on comparative tubera coxarum movement were quantified, including hip hike, -drop and range of motion. The robustness of each assessment method was established through comparison to sacrum-based overall motion asymmetry as the ground truth. RESULTS: Tubera coxarum-based lameness assessment was highly sensitive to all the unique lameness patterns and changes in pelvic rotation which a lame horse may adopt. None of the five visual lameness assessment methods was 100% robust across all conditions tested. For everyday clinical practice, comparing the upward movement amplitude of the RTC before right hind foot contact and of the LTC before left hind foot contact (Hip_hike_diff) would be the most robust single tubera coxarum-based visual assessment method. MAIN LIMITATIONS: In the absence of published data regarding the frequency of different movement patterns and hip rotation adaptations in clinical practice, this study cannot indicate the proportion of assessments that would be incorrect for a given visual assessment method. CONCLUSIONS: Using a single tubera coxarum-based visual hindlimb lameness assessment method may lead to incorrect clinical judgement. Therefore, using multiple assessment methods would be beneficial to substantiate impressions.

Severe psittacosis progressing to suspected organizing pneumonia and the role of corticosteroids.

BACKGROUND: Psittacosis is a systemic disease usually with respiratory involvement, caused by the obligate intracellular bacterium Chlamydia psittaci. Exposure to birds, the main zoonotic reservoir, is a major risk factor for infection. The spectrum of disease is highly variable, ranging from subclinical infection to severe pneumonia requiring mechanical ventilation. There is limited data on psittacosis progressing to organizing pneumonia and management of such cases. CASE PRESENTATION: A 63-year-old man was referred to a rural hospital with 11 days of fevers to 39 °C, myalgia, lethargy and several days of dry cough. After initial treatment with benzylpenicillin and doxycycline for left lower pneumonia found on CXR, the patient deteriorated with extensive bilateral consolidation on chest CT requiring mechanical ventilation. Atypical pneumonia screening was negative, however, exposure to a sick bird prior to symptom onset triggered testing for C. psittaci which was positive. Doxycycline was recommenced with minimal benefit, and organizing pneumonia was later suspected. The patient slowly improved with a weaning course of corticosteroids started after 19 days and was discharged from hospital. He unfortunately was re-admitted and died several months later. CONCLUSION: Severe pneumonia is a rare, but potentially life-threatening complication of psittacosis. We present a case of psittacosis which progressed to suspected organizing pneumonia despite appropriate antibiotics, and subsequent treatment with corticosteroids. This case suggests it may be useful to consider corticosteroids early in therapy for patients with severe psittacosis. Our paper underlines the need for further research to determine the best management of severe psittacosis to improve patient outcomes.

Caregiver experiences of paediatric inpatient cardiac services: A qualitative systematic review.

BACKGROUND: Advances in paediatric care have contributed to an increasing survival of children with complex heart disease. Yet, life-saving management demands prolonged inpatient admissions, which contribute to emotional and psychological distress for parents and other caregivers in a role of main custody. AIM: The purpose of this study was to identify, appraise and synthesise qualitative studies exploring caregivers' experiences of paediatric inpatient cardiac services, generating an understanding of their needs in hospital and informing priorities for change in healthcare delivery. METHODS: Searches were conducted in Medline, Allied and Complimentary Medicine Database, Cumulative Index of Nursing and Allied Health Literature, EMCARE, Scopus, PsychINFO, Proquest, OpenGrey and ETHOs from 2008-2019, reflecting recent advances in cardiac healthcare. Articles were selected using predetermined eligibility criteria dictating qualitative inquiry into caregiver perspectives whilst their child received hospital-based interventions for heart disease. All eligible studies underwent quality appraisal. Framework synthesis was used to analyse and summarise findings. RESULTS: Twenty-seven studies involving 689 caregivers from 11 countries were included. Three overarching themes were identified: 'emotional capacity to care', 'practicalities of caring', and 'the bigger picture of caring'. CONCLUSIONS: Through analysis and summary of qualitative primary research, this review captures the emotional challenges that caregivers face and practicalities of undertaking a caregiver role, whilst looking after their child with heart disease in hospital. The results widen the context of the caregiver role, encompassing the whole family unit beyond the hospital environment. This review exposes the impact of these challenges on caregiver competence, wellbeing and attachment to their unwell child, informing priorities for development of family-centred paediatric inpatient cardiac services.

Effect of gamified perceptual learning on visual detection and discrimination skills in equine gait assessment.

BACKGROUND: Visual assessment of equine lameness is an everyday veterinary task suffering from poor diagnostic accuracy. The aim of this study was to quantify the impact of the perceptual learning game 'LamenessTrainer' on skill development. METHODS: Thirty-six undergraduate veterinary students engaged in four game modules teaching the assessment of fore- and hindlimb lameness. Computer animations of horses in this game displayed 0% (sound) to 70% (moderately lame) vertical movement asymmetry of head and pelvis. Performance, learning effects, diagnostic accuracy, detection thresholds and survey responses were analysed. RESULTS: Following staircase learning, more than 80% of students reliably classified horses with ≥20% asymmetry for forelimb lameness, ≥40% asymmetry for simplified hindlimb lameness and ≥50% asymmetry for realistic hindlimb lameness. During random presentation, on average 82% of sound and 65% of lame horses were assessed correctly during forelimb lameness evaluation, dropping to 39% of sound and 56% of lame horses for hindlimb lameness. CONCLUSION: In less than two hours, systematic perceptual learning through deliberate practice can develop visual assessment skills to an accuracy level comparable to expert assessors scoring the same animations. Skills should be developed further to improve misclassifications of sound and mildly lame horses, especially for hindlimb lameness evaluation.

Nosocomial hepatitis A outbreak among healthcare workers and patients in a community hospital during an ongoing statewide outbreak.

OBJECTIVE: The Tennessee Department of Health (TDH) investigated a hepatitis A virus (HAV) outbreak to identify risk factors for infection and make prevention recommendations. DESIGN: Case series. SETTING: Community hospital. PARTICIPANTS: Healthcare workers (HCWs) or patients with laboratory-confirmed acute HAV infection during October 1, 2018-January 10, 2019. METHODS: HCWs with suspected or confirmed hepatitis A infections were interviewed to assess their exposures and activities. Patient medical records and hospital administrative records were reviewed to identify common exposures. We conducted a site investigation to assess knowledge of infection control practices among HCWs. Serum specimens from ill persons were tested for HAV RNA by polymerase chain reaction (PCR) and genotyped. RESULTS: We identified 6 HCWs and 2 patients with laboratory-confirmed HAV infection. All cases likely resulted from exposure to a homeless patient with a history of recreational substance use and undiagnosed HAV infection. Breaches in hand hygiene and use of standard precautions were identified. HAV RNA was detected in 7 serum specimens and all belonged to an identical strain of HAV genotype 1b. CONCLUSIONS: A hepatitis A outbreak among hospital patients and HCWs resulted from exposure to a single patient with undiagnosed HAV infection. Breakdowns in infection control practices contributed to the outbreak. The likelihood of nosocomial transmission can be reduced with proper hand hygiene, standard precautions, and routine disinfection. During community outbreaks, medical providers can better prevent ongoing transmission by including hepatitis A in the differential diagnosis among patients with a history of recreational substance use and homelessness.

First rib dysfunction in patients with neck and shoulder pain: a Delphi investigation.

BACKGROUND: First rib dysfunction is a possible cause of symptoms in patients with neck and/or shoulder pain. OBJECTIVES: To explore therapists' perceptions of useful diagnostic criteria to identify first rib dysfunction. METHODS: A Delphi survey over four rounds involving international manual therapy experts who were asked to agree on which items were most useful in identifying first rib dysfunction. RESULTS: Consensus (>70% agreement) was reached on key aspects of first rib dysfunction being first rib mobility restriction, upper limb symptom distribution, and a subclassification into two subgroups was suggested. The main clinical findings suggested were: painful and restricted neck movements and shoulder girdle loading activities; positive Upper Limb Neural Test 1; direct palpation of first rib, neural structures, and scalene muscles; pain and hypomobility of first rib accessory movements with improvement after mobilization. The cervical rotation lateral-flexion test was considered a useful, although not widely used test among the experts. Its diagnostic accuracy and interpretation in isolation was questioned. CONCLUSIONS: This Delphi study produced a cluster of clinical tests aimed to identify first rib dysfunction in patients with neck and/or shoulder conditions. However, these need to be tested out in further research to establish reliability and validity.

Patients' and caregivers' perspectives on access to kidney replacement therapy in rural communities: systematic review of qualitative studies.

OBJECTIVE: Patients with chronic kidney disease (CKD) requiring kidney replacement therapy (KRT) in rural communities encounter many barriers in accessing equitable care and have worse outcomes compared with patients in urban areas. This study aims to describe the perspectives of patients and caregivers on access to KRT in rural communities to inform strategies to maximise access to quality care, and thereby reduce disadvantage, inequity and improve health outcomes. SETTING: 18 studies (n=593 participants) conducted across eight countries (Australia, Canada, the UK, New Zealand, Ghana, the USA, Tanzania and India). RESULTS: We identified five themes: uncertainty in navigating healthcare services (with subthemes of struggling to absorb information, without familiarity and exposure to options, grieving former roles and yearning for cultural safety); fearing separation from family and home (anguish of homesickness, unable to fulfil family roles and preserving sense of belonging in community); intense burden of travel and cost (poverty of time, exposure to risks and hazards, and taking a financial toll); making life-changing sacrifices; guilt and worry in receiving care (shame in taking resources from others, harbouring concerns for living donor, and coping and managing in isolation). CONCLUSION: Patients with CKD in rural areas face profound and inequitable challenges of displacement, financial burden and separation from family in accessing KRT, which can have severe consequences on their well-being and outcomes. Strategies are needed to improve access and reduce the burden of obtaining appropriate KRT in rural communities.

Do patients with low back pain remember physiotherapists' advice? A mixed-methods study on patient-therapist communication.

OBJECTIVES: The primary aim of this study was to determine if the advice physiotherapists think they provide to patients with low back pain (LBP) is what the patients remember and take away from the clinical encounter. The secondary aim was to determine which factors may influence the retention of this advice. METHODS: The first component of the study used questionnaires completed by patients and therapists after the initial visit. Related questionnaires of patients and therapists were screened for inconsistencies. The second component of the study involved semi-structured interviews. RESULTS: Ninety pairs of questionnaires were completed. Therapists provided patients with one (N = 90), two (N = 85) or three (N = 51) items of advice regarding the management of their LBP. All patients remembered the first item of advice, 92% remembered a second, and 67% remembered the third piece of advice. All items of advice were deemed either 'relevant' or 'very relevant' by 97% of the patients. After the analysis of 14 interviews, data saturation was reached. Four themes emerged from the data analysis of the interviews: (a) Evaluation type, (b) Exercise factors, (c) Patient concerns about their diagnosis, and (d) Patient expectations. DISCUSSION: In most cases, patients remembered what therapists told them and considered that the advice provided was relevant. Based on the qualitative data, patients were more likely to remember what therapists said when: (a) shared decision making was used during the initial encounter, (b) prescribed exercises were simple to perform and few in number, (c) patients' concerns about their diagnosis were addressed, and (d) patients' expectations were identified and addressed.

Collaborative Development of a Shared Framework for Competency-Based Veterinary Education.

Competency-based medical education is an educational innovation implemented in health professions worldwide as a means to ensure graduates meet patient and societal needs. The focus on student-centered education and programmatic outcomes offers a series of benefits to learners, institutions and society. However, efforts to establish a shared, comprehensive competency-based framework in veterinary education have lagged. This article reports on the development and outcome of a competency-based veterinary education (CBVE) framework created through multi-institutional collaboration with international input from veterinary educators and veterinary educational leaders. The CBVE Framework is designed to reflect the competencies expected of new graduates from member institutions of the Association of American Veterinary Medical Colleges (AAVMC). The CBVE Framework consists of nine domains of competence and 32 competencies, each supplemented with illustrative sub-competencies to guide veterinary schools in implementing competency-based education in their local context. The nine domains of competence are: clinical reasoning and decision-making; individual animal care and management; animal population care and management; public health; communication; collaboration; professionalism and professional identity; financial and practice management; and scholarship. Developed through diverse input to facilitate broad adoption, the CBVE Framework provides the foundation for competency-based curricula and outcomes assessment in veterinary education internationally. We believe that other groups seeking to design a collective product for broad adoption might find useful the methods used to develop the CBVE Framework, including establishing expertise diversity within a small-to-medium size working group, soliciting progressive input and feedback from stakeholders, and engaging in consensus building and critical reflection throughout the development process.

Collaborative Development of Core Entrustable Professional Activities for Veterinary Education.

Entrustable professional activities (EPAs) have been proposed as a practical framework for the implementation of competency-based education. As veterinary education moves toward a competency-based approach, core EPAs provide a context for assessment of workplace activities. This article reports on the development of eight core clinical EPAs for veterinary education created through multi-institutional collaboration, with international input from veterinary educators and veterinary educational leaders. These core EPAs are intended as minimal expectations for clinical activities that should be assessed for every graduate of Association of American Veterinary Medical Colleges member institutions. Adoption of the core EPAs and the associated Competency-Based Veterinary Education (CBVE) framework by veterinary schools is intended to promote Day One graduate competence and thereby enhance patient care and client service.

Are within and/or between session improvements in pain and function prognostic of medium and long-term improvements in musculoskeletal problems? A systematic review.

BACKGROUND: Initial or between session improvements in pain and/or function are often considered to be predictive of ultimate outcomes in musculoskeletal problems. OBJECTIVE: To determine the long-term prognostic value of within and between session improvements to pain and function. DESIGN: Systematic review of relevant literature. METHOD: A search was made of multiple databases (Pubmed/Medline, Cochrane, Cinahl, and AMed) using relevant search terms. Titles, abstracts, and then full texts were filtered to find articles that met the strict inclusion/exclusion criteria. Searching, data extraction, and quality assessment, using GRADE, were done independently by two authors. Disagreements were resolved by consensus. RESULTS: Only 13 articles met the criteria for inclusion. For the effect of pain location or pain intensity changes in the first treatment session on medium or long-term pain, disability, return-to-work, or global outcomes nine outcomes were available. Findings were mostly inconclusive (5) or negative (3). There was only one study evaluating between session improvements with ambiguous results. There were no studies evaluating the prognostic value of early improvements in function. CONCLUSIONS: There is no conclusive evidence to support the concept that early changes in pain location or pain intensity offer a good longer-term prognosis on a variety of outcomes; and no evidence relating to early improvements in function. The idea that patients who appear to improve in the first treatment session will do well longer term is not supported by the literature.

Concerns related to the accurate identification of anterior derangement syndrome in mechanical diagnosis and therapy for low back pain: A case report.

Background: In Mechanical Diagnosis and Therapy (MDT), patients with low back pain (LBP) are classified into subgroups to guide a management strategy. A common subgroup where symptoms improve with lumbar extension is labeled posterior derangement syndrome. A less common subgroup where symptoms improve with lumbar flexion is labeled anterior derangement syndrome. Case Presentation: The patient was a 23-year-old woman with intermittent LBP and discomfort over the left lower extremity was initially diagnosis with posterior derangement syndrome. At the initial and second consultations, postural correction and home exercises with lumbar extension were prescribed. However, at the third consultation, sustained lumbar extension revealed worsening of symptoms and function, which resulted in a revised diagnosis of anterior derangement syndrome. Complete recovery was achieved using exercises with lumbar flexion over 6 weeks. Outcomes: The patient wore the LUMOback in daily life, which is a wearable device measuring pelvic angle and acceleration, for 1 week before the initial MDT consultation and for 6 weeks until discharge. The posture scores (%) is the proportion of time in a week with neutral pelvic tilt. In this patient, the posture score decreased greater than a minimum detectable change of 11.7% when MDT classification changed to anterior derangement. Conclusions: This case report indicates the importance of sustained loading to identify the correct derangement syndrome, and follow-up sessions to confirm or reject the initial diagnosis by monitoring symptom and functional changes carefully. Habitual posture may be associated with reduction and aggravation of symptoms.
