Systematic Review to Inform a World Health Organization (WHO) Clinical Practice Guideline: Benefits and Harms of Needling Therapies for Chronic Primary Low Back Pain in Adults.

PURPOSE: Evaluate benefits and harms of needling therapies (NT) for chronic primary low back pain (CPLBP) in adults to inform a World Health Organization (WHO) standard clinical guideline. METHODS: Electronic databases were searched for randomized controlled trials (RCTs) assessing NT compared with placebo/sham, usual care, or no intervention (comparing interventions where the attributable effect could be isolated). We conducted meta-analyses where indicated and graded the certainty of evidence. RESULTS: We screened 1831 citations and 109 full text RCTs, yeilding 37 RCTs. The certainty of evidence was low or very low across all included outcomes. There was little or no difference between NT and comparisons across most outcomes; there may be some benefits for certain outcomes. Compared with sham, NT improved health-related quality of life (HRQoL) (physical) (2 RCTs; SMD = 0.20, 95%CI 0.07; 0.32) at 6 months. Compared with no intervention, NT reduced pain at 2 weeks (21 RCTs; MD = - 1.21, 95%CI - 1.50; - 0.92) and 3 months (9 RCTs; MD = - 1.56, 95%CI - 2.80; - 0.95); and reduced functional limitations at 2 weeks (19 RCTs; SMD = - 1.39, 95%CI - 2.00; - 0.77) and 3 months (8 RCTs; SMD = - 0.57, 95%CI - 0.92; - 0.22). In older adults, NT reduced functional limitations at 2 weeks (SMD = - 1.10, 95%CI - 1.71; - 0.48) and 3 months (SMD = - 1.04, 95%CI - 1.66; - 0.43). Compared with usual care, NT reduced pain (MD = - 1.35, 95%CI - 1.86; - 0.84) and functional limitations (MD = - 2.55, 95%CI - 3.70; - 1.40) at 3 months. CONCLUSION: Based on low to very low certainty evidence, adults with CPLBP experienced some benefits in pain, functioning, or HRQoL with NT; however, evidence showed little to no differences for other outcomes.

Investigating force-time characteristics of prone thoracic SMT and self-reported patient outcome measures: a feasibility study.

BACKGROUND: Spinal manipulative therapy (SMT) is commonly used to treat musculoskeletal conditions, including thoracic spine pain. Applying patient-specific force-time characteristics are believed to be important to improve SMT's effectiveness. Investigating SMT as part of a multimodal approach is fundamental to account for the complexity of chiropractic clinical practice. Therefore, pragmatic investigations balancing minimal disruptions to the clinical encounter at the same time as ensuring a robust data quality with rigorous protocols are needed. Consequently, preliminary studies are required to assess the study protocol, quality of data recorded and the sustainability of such investigation. Therefore, this study examined the feasibility of investigating SMT force-time characteristics and clinical outcome measures in a clinical setting. METHODS: In this mixed-methods study, providers recorded thoracic SMT force-time characteristics delivered to patients with thoracic spinal pain during regular clinical encounters. Self-reported clinical outcomes of pain, stiffness, comfort during the SMT (using an electronic visual analogue scale), and global rating of change scale were measured before and after each SMT application. Feasibility was quantitatively assessed for participant recruitment, data collection and data quality. Qualitative data assessed participants' perceptions on the impact of data collection on patient management and clinical flow. RESULTS: Twelve providers (58% female, 27.3 ± 5.0 years old) and twelve patients (58% female, 37.2 ± 14.0 years old) participated in the study. Enrolment rate was greater than 40%, data collection rate was 49% and erroneous data was less than 5%. Participant acceptance was good with both providers and patients reporting positive experience with the study. CONCLUSIONS: Recording SMT force-time characteristics and self-reported clinical outcome measures during a clinical encounter may be feasible with specific modification to the current protocol. The study protocol did not negatively impact patient management. Specific strategies to optimize the data collection protocol for the development of a large clinical database are being developed.

Effects of Distinct Force Magnitude of Spinal Manipulative Therapy on Blood Biomarkers of Inflammation: A Proof of Principle Study in Healthy Young Adults.

OBJECTIVES: The purpose of this preliminary study was to determine the influence of thoracic spinal manipulation therapy (SMT) of different force magnitudes on blood biomarkers of inflammation in healthy adults. METHODS: Nineteen healthy young adults (10 female, age: 25.6 ± 1.2 years) were randomized into the following 3 groups: (1) control (preload only), (2) single thoracic SMT with a total peak force of 400N, and (3) single thoracic SMT with a total peak force of 800N. SMT was performed by an experienced chiropractor, and a force-plate embedded treatment table (Force Sensing Table Technology) was used to determine the SMT force magnitudes applied. Blood samples were collected at pre intervention (baseline), immediately post intervention, and 20 minutes post intervention. A laboratory panel of 14 different inflammatory biomarkers (pro, anti, dual role, chemokine, and growth factor) was assessed by multiplex array. Change scores from baseline of each biomarker was used for statistical analysis. Two-way repeated-measures analysis of variance was used to investigate the interaction and main effects of intervention and time on cytokines, followed by Tukey's multiple comparison test (P ≤ .05). RESULTS: A between-group (800N vs 400N) difference was observed on interferon-gamma, interleukin (IL)-5, and IL-6, while a within-group difference (800N: immediately vs 20 minutes post-intervention) was observed on IL-6 only. CONCLUSION: In this study, we measured short-term changes in plasma cytokines in healthy young adults and found that select plasma pro-inflammatory and dual-role cytokines were elevated by higher compared to lower SMT force. Our findings aid to advance our understanding of the potential relationship between SMT force magnitude and blood cytokines and provide a healthy baseline group with which to compare similar studies in clinical populations in the future.

The impact and public health response of chiropractors to the COVID-19 pandemic: a survey across four continents.

BACKGROUND: The unprecedented impact of COVID-19 on healthcare professionals has implications for healthcare delivery, including the public health guidance provided to patients. This study aims to assess the response and impact of COVID-19 on chiropractors internationally, and examines the public health response of chiropractors to the COVID-19 pandemic practising under a musculoskeletal spine-care versus subluxation-based care paradigm. METHODS: A survey was distributed to chiropractors in Australia, Canada, Denmark, Hong Kong, United Kingdom and United States (Oct. 2nd-Dec. 22nd, 2020) via professional bodies/publications, and social media. Questions were categorised into three domains: socio-demographic, public health response and business/financial impact. Multivariable logistic regression explored survey items associated with chiropractors practising under different self-reported paradigms. RESULTS: A total of 2061 chiropractors representing four global regions completed the survey. Our recruitment method did not allow the calculation of an accurate response rate. The vast majority initiated COVID-19 infection control changes within their practice setting, including increased disinfecting of treatment equipment (95%), frequent contact areas (94%) and increased hand hygiene (94%). While findings varied by region, most chiropractors (85%) indicated that they had implemented regulator advice on the use of personal protective equipment (PPE). Suspension of face-to-face patient care during the peak of the pandemic was reported by 49% of the participants with 26% implementing telehealth since the pandemic began. Chiropractors practising under a musculoskeletal spine-care paradigm were more likely to implement some/all regulator advice on patient PPE use (odds ratio [OR] = 3.25; 95% confidence interval [CI]: 1.57, 6.74) and practitioner PPE use (OR = 2.59; 95% CI 1.32, 5.08); trust COVID-19 public health information provided by government/World Health Organisation/chiropractic bodies (OR = 2.47; 95% CI 1.49, 4.10), and initiate patient telehealth in response to COVID-19 (OR = 1.46; 95% CI 1.02, 2.08) compared to those practising under a subluxation-based paradigm. CONCLUSIONS: Chiropractors who responded to our survey made substantial infectious control changes in response to COVID-19. However, there was regional variation in the implementation of the advised practitioner and patient use of PPE and limited overall use of telehealth consultations by chiropractors during COVID-19. Musculoskeletal spine-care chiropractors were more adaptive to certain COVID-19 public health changes within their practice setting than subluxation-based chiropractors.

Expert consensus on a standardised definition and severity classification for adverse events associated with spinal and peripheral joint manipulation and mobilisation: protocol for an international e-Delphi study.

INTRODUCTION: Spinal and peripheral joint manipulation (SMT) and mobilisation (MOB) are widely used and recommended in the best practice guidelines for managing musculoskeletal conditions. Although adverse events (AEs) have been reported following these interventions, a clear definition and classification system for AEs remains unsettled. With many professionals using SMT and MOB, establishing consensus on a definition and classification system is needed to assist with the assimilation of AEs data across professions and to inform research priorities to optimise safety in clinical practice. METHODS AND ANALYSIS: This international multidisciplinary electronic Delphi study protocol is informed by a scoping review and in accordance with the 'Guidance on Conduction and Reporting Delphi Studies'. With oversight from an expert steering committee, the study comprises three rounds using online questionnaires. Experts in manual therapy and patient safety meeting strict eligibility criteria from the following fields will be invited to participate: clinical, medical and legal practice, health records, regulatory bodies, researchers and patients. Round 1 will include open-ended questions on participants' working definition and/or understanding of AEs following SMT and MOB and their severity classification. In round 2, participants will rate their level of agreement with statements generated from round 1 and our scoping review. In round 3, participants will rerate their agreement with statements achieving consensus in round 2. Statements reaching consensus must meet the a priori criteria, as determined by descriptive analysis. Inferential statistics will be used to evaluate agreement between participants and stability of responses between rounds. Statements achieving consensus in round 3 will provide an expert-derived definition and classification system for AEs following SMT and MOB. ETHICS AND DISSEMINATION: This study was approved by the Canadian Memorial Chiropractic College Research Ethics Board and deemed exempt by Parker University's Institutional Review Board. Results will be disseminated through scientific, professional and educational reports, publications and presentations.

Characterization of thoracic spinal manipulation and mobilization forces in older adults.

BACKGROUND: Spinal mobilization and spinal manipulation are common interventions used by manual therapists to treat musculoskeletal conditions in older adults. Their force-time characteristics applied to older adults' thoracic spine are important considerations for effectiveness and safety but remain unknown. This study aimed to describe the force-time characteristics of posterior-to-anterior spinal mobilization and manipulation delivered to older adults' thoracic spine. METHODS: Twenty-one older adults (≥65 years) with no thoracic pain received posterior-to-anterior thoracic spinal mobilization and/or manipulation with the force characteristics a chiropractor deemed appropriate. Six-degree-of-freedom load cells and an instrumented treatment table recorded the force characteristics of both interventions at the clinician-participant and participant-table interfaces, respectively. Preload force, total peak force, time to peak and loading rate were analyzed descriptively. FINDINGS: Based on data from 18 adults (56% female; average: 70 years old), mean resultant spinal mobilization forces at the clinician-participant interface were: 220 ± 51 N during preload, 323 ± 67 N total peak force, and 312 ± 38 ms time to peak. At the participant-table interface, mobilization forces were 201 ± 50 N during preload, 296 ± 63 N total peak force, and 308 ± 44 ms time to peak. Mean resultant spinal manipulation forces at the clinician-participant interface were: 260 ± 41 N during preload, 470 ± 46 N total peak force, and 165 ± 28 ms time to peak. At the participant table interface, spinal manipulation forces were 236 ± 47 N during preload, 463 ± 57 N total peak force, and 169 ± 28 ms time to peak. INTERPRETATION: Results suggest older adults experience unique, but comparable force-time characteristics during spinal mobilization and manipulation delivered to their thoracic spine compared to the ones delivered to younger adults described in the literature.

The profile of older adults seeking chiropractic care: a secondary analysis.

BACKGROUND: Musculoskeletal conditions are the primary reason older adults seek general medical care, resulting in older adults as the highest consumers of health care services. While there is high use of chiropractic care by older adults, there is no recent, specific data on why older adults seek chiropractic care and how chiropractors manage conditions. Therefore, the purpose of this study was to describe the demographic characteristics of older adults seeking chiropractic care, and to report problems diagnosed by chiropractors and the treatment provided to older adults who seek chiropractic care. METHODS: A secondary data analysis from two, large cross-sectional observational studies conducted in Australia (COAST) and Canada (O-COAST). Patient encounter and diagnoses were classified using the International Classification of Primary Care, 2nd edition (ICPC-2), using the Australian ICPC-2 PLUS general practice terminology and the ICPC-2 PLUS Chiro terminology. Descriptive statistics were used to summarize chiropractor, patient and encounter characteristics. Encounter and patient characteristics were compared between younger (< 65 years old) and older (≥65 years old) adults using χ2 tests or t-tests, accounting for the clustering of patients and encounters within chiropractors. RESULTS: A total of 6781 chiropractor-adult patient encounters were recorded. Of these, 1067 encounters were for persons aged > 65 years (16%), from 897 unique older patients. The most common diagnosis within older adult encounters was a back problem (56%), followed by neck problems (10%). Soft tissue techniques were most frequently used for older patients (85 in every 100 encounters) and in 29 of every 100 encounters, chiropractors recommended exercise to older patients as a part of their treatment. CONCLUSIONS: From 6781 chiropractor-adult patient encounters across two countries, one in seven adult chiropractic patients were > 65 years. Of these, nearly 60% presented with a back problem, with neck pain and lower limb problems the next most common presentation to chiropractors. Musculoskeletal conditions have a significant burden in terms of disability in older adults and are the most commonly treated conditions in chiropractic practice. Future research should explore the clinical course of back pain in older patients seeking chiropractic care and compare the provision of care to older adults across healthcare professions.

Chiropractic student diagnosis and management of headache disorders: A survey examining self-perceived preparedness and clinical proficiency.

OBJECTIVE: To explore the self-perceived preparedness and clinical proficiency in headache diagnosis and management of Australian chiropractic students in senior years of study. METHODS: Australian chiropractic students in the 4th (n = 134) and 5th year (n = 122) of 2 chiropractic university programs were invited to participate in an online cross-sectional survey. Descriptive analyses were conducted for all variables. Post hoc analyses were performed using simple linear regression to evaluate the relationship between self-perceived preparedness and correctness of headache diagnosis and management scores. RESULTS: Australian chiropractic students in senior years demonstrated moderate overall levels of self-perceived preparedness and proficiency in their ability to diagnose and manage headache disorders. Final-year students had a slightly higher self-perceived preparedness and proficiency in headache diagnosis and management compared to those students in the 4th year of study. There was no relationship between self-perceived preparedness and correctness of headache diagnosis and management for either 4th- or 5th-year chiropractic students. CONCLUSION: Our findings suggest that there may be gaps in graduate chiropractic student confidence and proficiency in headache diagnosis and management. These findings call for further research to explore graduate chiropractic student preparedness and proficiency in the diagnosis and management of headache disorders.

Leadership and capacity building in chiropractic research: report from the first CARL cohort.

The Chiropractic Academy for Research Leadership (CARL) was formed in 2016 in response to a need for a global network of early career researchers and leaders in the chiropractic profession. Thirteen fellows were accepted competitively and have since worked together at residentials and virtually on many research and leadership projects. In 2020, the CARL program ended for this first cohort, and it is now timely to take stock and reflect on the achievements and benefits of the program. In this paper we present the structure of CARL, the scientific and leadership outputs as well as the personal value of CARL for the participating fellows. As a result of the success of the first CARL cohort, organizations from Europe, North America, and Australia have supported a second cohort of 14 CARL fellows, who were competitively accepted into the program in early 2020.

Symptoms patients receiving manual therapy experienced and perceived as adverse: a secondary analysis of a survey of patients' perceptions of what constitutes an adverse response.

Background: Previous qualitative studies demonstrated that the process by which patients determined whether a response to manual therapy is adverse is very complex. However, it remains unknown which responses to manual therapy patients perceived as adverse. Objective: To describe symptoms patients experienced and perceived as adverse following manual therapy and to explore predictors of adverse responses (AR) for the body region with the greatest number of AR. We hypothesized that patients receiving manual therapy for neck conditions would present with more symptoms perceived as AR. Methods: This was a secondary analysis of a previous cross-sectional survey of 324 patients receiving manual therapy from Canadian physiotherapists. It included questions regarding symptoms patients experienced after a treatment including manual therapy and perceived as adverse. Poisson and negative binomial regression were used to determine factors associated with the number of symptoms that patients experienced and perceived as adverse. Results: Symptoms that affected patient's functionality were most often perceived as AR. The neck region was the body part with the greatest number of perceived AR (n = 83). Patients with neck pain who agreed that education may change their experience with AR had a lower incidence rate of AR. Conclusion: Findings indicate that communication regarding post-treatment symptoms between clinicians and patients is important and can potentially influence patients' perception of post-treatment symptoms.

Serious adverse events following lumbar spine mobilization or manipulation and potential associated factors: a systematic review protocol.

OBJECTIVES: The objectives of this review are to describe the serious adverse events reported in the literature following lumbopelvic mobilization and manipulation, and identify patient, provider, and/or treatment factors that may be associated with serious adverse events after these interventions. INTRODUCTION: Spinal mobilization and manipulation are types of conservative care commonly used to treat people with low back pain and other musculoskeletal conditions of the lumbar spine and pelvis. Although most adverse events following these interventions are benign and transient, serious adverse events have been reported mostly following spinal manipulative therapy. Given the significant impact serious adverse events can have on patients' lives, identifying factors that may be associated with serious adverse events following spinal mobilization and manipulation of the low back and pelvis would allow for a more specific pre-treatment screening, potentially reducing the occurrence of serious adverse events following these popular interventions and contributing to a safer treatment delivery. INCLUSION CRITERIA: This review will consider interventional and observational studies that report serious adverse events following lumbopelvic spinal mobilization or manipulation experienced by people of any age. Examples of serious adverse events include disc herniation, cauda equina syndrome, and vertebral fracture. METHODS: MEDLINE, Embase, CINAHL, PubMed, The Cochrane Database of Systematic Reviews/Central Register of Controlled Trials, and Index to Chiropractic Literature (ICL) databases will be searched as well as OpenGrey and ProQuest Dissertations and Theses. Two independent reviewers will screen titles and abstracts of identified references as well as the full text of identified studies, and extract data following a standardized data extraction form. Data will be summarized, categorized, and a comprehensive narrative summary will be presented. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42019122339.

Patient safety in chiropractic teaching programs: a mixed methods study.

BACKGROUND: Patient safety research has lagged within academic settings, including chiropractic teaching institutions. To develop a robust patient safety culture, the Institute of Medicine emphasized the need for employee's attitudes to be understanding and positive. To initiate the assessment of the current culture and future needs, this study evaluated patient safety attitudes among chiropractic teaching clinic stakeholders (supervising clinicians, student interns, and administrative staff) and compared their standardized survey scores to established medical survey databases. METHODS: We conducted a cross-sectional, mixed methods survey design with quantitative analytic priority. Chiropractic interns, clinical faculty, and clinic staff of 5 international chiropractic educational programs completed a modified version of the Agency for Healthcare Research and Quality (AHRQ) Patient Safety Culture for Medical Offices Survey with open-ended comment fields between 2014 and 2016. Composite means of positive responses were calculated and compared to patient safety, quality of care, and overall self-ratings benchmarks from Canadian providers and academic settings in the AHRQ database. Qualitative responses were thematically categorized for a convergent analysis of quantitative results for the chiropractic sample. RESULTS: Chiropractic survey response rate was 45.3% (n = 645). Quantitative survey results indicated moderate scores and ranges (57-85%) on all patient safety dimensions for the chiropractic samples. Academic medicine and chiropractic providers' benchmarks scored higher positive responses than chiropractic teaching clinics on most quantitative dimensions, except for work pressure/pace. Teamwork, organizational learning, and patient tracking/follow-up were the most positively endorsed quantitative dimensions, with communication, staff training, office standardization, and leadership support considered areas for improvement in both settings. Qualitative responses for the chiropractic clinics identified a need for open communication; additional staff training and student involvement in creating safety cultures; standardization of office processes including information exchange, scheduling, and equipment maintenance; and leadership support that focused on decreasing work pressure/pace and setting safety priorities. CONCLUSION: As the first report of patient safety attitudes from stakeholders in chiropractic teaching clinics, specific areas of improvement were identified. Chiropractic teaching programs might consider incorporating these and related patient safety concepts into their formal curricula. Mixed methods approach offers teaching clinics opportunities to assess stakeholders' insights and enhance safe delivery of chiropractic care.

Adverse events associated with paediatric massage therapy: a systematic review.

INTRODUCTION: Massage therapy (MT) is frequently used in children. No study has systematically assessed its safety in children and adolescents. We systematically review adverse events (AEs) associated with paediatric MT. METHODS: We searched seven electronic databases from inception to December 2018. We included studies if they (1) were primary studies published in a peer-reviewed journal, (2) involved children aged 0-18 years and (3) a type of MT was used for any indication. No restriction was applied to language, year of publication and study design. AEs were classified based on their severity and association to the intervention. RESULTS: Literature searches identified 12 286 citations, of which 938 citations were retrieved for full-text evaluation and 60 studies were included. In the included studies, 31 (51.6%) did not report any information on AEs, 13 (21.6%) reported that no AE occurred and 16 studies (26.6%) reported at least one AE after MT. There were 20 mild events (grade 1) that resolved with minimal intervention, 26 moderate events (grades 2-3) that required medical intervention, and 18 cases of severe AEs (grades 4-5) that resulted in hospital admission or prolongation of hospital stay; of these, 17 AEs were volvulus in premature infants, four of which were ultimately fatal events. CONCLUSION: We identified a range of AEs associated with MT use, from mild to severe. Unfortunately, the majority of included studies did not report if an AE occurred or not, leading to publication bias. This review reports an association between abdominal massage with volvulus without malrotation in preterm infants; it is still to be defined if this is casual or not, but our findings warrant caution in the use of abdominal massage in preterm infants.

Beliefs, perceptions and practices of chiropractors and patients about mitigation strategies for benign adverse events after spinal manipulation therapy.

BACKGROUND: Approximately 50% of patients who receive spinal manipulative therapy (SMT) experience some kind of adverse event (AE), typically benign and transient in nature. Regardless of their severity, mitigating benign AEs is important to improve patient experience and quality of care. The aim of this study was to identify beliefs, perceptions and practices of chiropractors and patients regarding benign AEs post-SMT and potential strategies to mitigate them. METHODS: Clinicians and patients from two chiropractic teaching clinics were invited to respond to an 11-question survey exploring their beliefs, perceptions and practices regarding benign AEs post-SMT and strategies to mitigate them. Responses were analyzed using descriptive statistics. RESULTS: A total of 39 clinicians (67% response rate) and 203 patients (82.9% response rate) completed the survey. Most clinicians (97%) believed benign AEs occur, and 82% reported their own patients have experienced one. For patients, 55% reported experiencing benign AEs post-SMT, with the most common symptoms being pain/soreness, headache and stiffness. While most clinicians (61.5%) reported trying a mitigation strategy with their patients, only 21.2% of patients perceived their clinicians had tried any mitigation strategy. Clinicians perceived that patient education is most likely to mitigate benign AEs, followed by soft tissue therapy and/or icing after SMT. Patients perceived stretching was most likely to mitigate benign AEs, followed by education and/or massage. CONCLUSIONS: This is the first study comparing beliefs, perceptions and practices from clinicians and patients regarding benign AEs post-SMT and strategies to mitigate them. This study provides an important step towards identifying the best strategies to improve patient safety and improve quality of care.

Assessing Adverse Events After Chiropractic Care at a Chiropractic Teaching Clinic: An Active-Surveillance Pilot Study.

OBJECTIVE: This study aimed to assess the feasibility of implementing an active-surveillance reporting system within a chiropractic teaching clinic and subsequently determining the frequency of adverse events (AEs) after treatment administered by chiropractic interns. METHODS: Interns were invited to collect data from patients using 3 questionnaires that recorded patient symptom change: 2 completed by the patient (before and 7 days after treatment) and 1 completed by the intern (immediately after treatment). Worsened and new symptoms were considered AEs. Qualitative interviews were conducted with clinicians and interns to assess the feasibility of implementing the reporting system, with resulting data categorized under 4 domains: acceptability, implementation, practicality, and integration. RESULTS: Of the 174 eligible interns, 80 (46.0%) collected data from 364 patient encounters, with 119 (32.7%) returning their posttreatment form. Of the 89 unique patients (mean age = 39.5 years; 58.4% female, 41.6% male), 40.1% presented with low back pain and 31.1% with neck pain. After treatment, 25 symptoms (8.9%) were identified as AEs, mostly reported by patients as worsening discomfort or pain. Data from qualitative interviews suggest that the AE reporting system was well accepted; however, proposed specific modifications include use of longitudinal electronic surveys. CONCLUSION: Our findings suggest that it is feasible to conduct an active-surveillance reporting system at a chiropractic teaching clinic. Important barriers and facilitators were identified and will be used to inform future work regarding patient safety education and research.

Lessons learned from cases of rib fractures after manual therapy: a case series to increase patient safety.

OBJECTIVE: To identify commonalities among cases of rib fractures after spinal manipulative therapy (SMT); discuss chiropractors' case management perspectives; and propose strategies for prevention and/or management of future cases. METHODS: Semi-structured interviews were conducted with chiropractors who identified cases of rib fractures after SMT at a chiropractic institution's teaching clinics. Patient characteristics, incident characteristics, and chiropractors' perspectives were collected and analysed. RESULTS: Three chiropractors were interviewed, each identifying one case. Patient ages ranged from 57-77; two were female; two had osteopenia; two cases involved thoracic SMT; and one involved lumbar SMT. Chiropractors agreed that verifying and updating potential contributing factors for rib fractures, transparent communication prior to SMT and/or after the adverse event (AE) occurrence, and enhancing student education on AE management were important. CONCLUSION: Important lessons can be learned from AEs, despite their infrequent occurrences. A more open and constructive patient safety environment is needed within the chiropractic profession.

OBJECTIF: Établir les points communs entre des cas de fractures des côtes après des manipulations vertébrales (MV); examiner des points de vue de chiropraticiens sur la prise en charge de cas; proposer des stratégies de prévention et/ou de prise en charge des cas à venir. MÉTHODOLOGIE: On a fait des entrevues semi-structurées avec des chiropraticiens travaillant à la clinique d'un établissement d'enseignement de la chiropratique et ayant identifié des cas de fractures de côtes après des MV. Les caractéristiques des patients, les caractéristiques des incidents et les points de vue des chiropraticiens ont été recueillis et analysés. RÉSULTATS: Trois chiropraticiens ont été interrogés, chacun ayant identifié un cas. Les patients étaient âgés de 57 à 77 ans; deux étaient de sexe féminin; deux souffraient d'ostéopénie; deux cas avaient été traités par manipulations thoraciques et un cas par manipulations lombaires. Les chiropraticiens ont convenu qu'il était important de vérifier et de mettre à jour les facteurs contributoires potentiels de fractures des côtes, d'informer le patient, en toute transparence, avant d'effectuer des MV et après la survenue d'un événement (ÉI) et d'améliorer la formation des étudiants sur la prise en charge des ÉI. CONCLUSION: Les ÉI, bien qu'ils soient rares, peuvent nous permettent de tirer d'importantes leçons. Une attitude plus ouverte et plus constructive envers la sécurité du patient s'impose chez les chiropraticiens.

Association of Exposures to Seated Postures With Immediate Increases in Back Pain: A Systematic Review of Studies With Objectively Measured Sitting Time.

OBJECTIVE: The purpose of this study was to conduct a systematic review of studies to determine whether sitting time measured objectively (by laboratory controlled time trial, direct observation, or wearable sensor) is associated with the immediate increase in low back pain (LBP) (determined by pain scale rating) in people >18 years of age. METHODS: Four databases (PubMed, EMBASE, SPORTDiscus, and Cumulative Index to Nursing and Allied Health Literature) were searched from inception to September 1, 2018. Randomized controlled trials and cohort and cross-sectional studies, where objectively measured sitting time was temporally matched with a measure of LBP in adults, were included. Studies without a control session conducted on a separate day were excluded. Screening, full-text review, data extraction, and risk of bias assessment (Quality In Prognosis Studies) of included papers were performed independently by 2 reviewers, with a third available to resolve disagreements. RESULTS: In total, 609 articles were identified, 361 titles/abstracts were screened,75 full-text articles were assessed for eligibility, and 10 met the inclusion criteria. All but 1 reported sitting time to be associated with an immediate increase in LBP. Six of these reported clinically relevant pain levels (n = 330). Half of the included studies were rated as having a low risk of bias and the remaining were rated as having a moderate risk of bias. CONCLUSION: Prolonged sitting increases immediate reporting of LBP in adults; however, no conclusion between sitting and clinical episodes of LBP can be made. Based upon these findings, we recommend that future prospective studies should match objectively measured sitting with temporally related pain measurements to determine whether prolonged sitting can trigger a clinical episode of LBP.

Clinicians' Ability to Detect a Palpable Difference in Spinal Stiffness Compared With a Mechanical Device.

OBJECTIVE: The purpose of this study was to quantify the threshold at which clinicians can detect a difference in spinal stiffness of the thoracic and lumbar spine via palpation and then determine if this detection threshold would affect a clinician's ability to identify changes in spinal stiffness as measured by an objective instrument. METHODS: In this study, the threshold at which a change in spinal stiffness was detected was quantified in 12 experienced clinicians (physical therapists and doctors of chiropractic) by changing the differential stiffness in 2 inflatable targets until the clinician could no longer identify which was stiffer. In the second part of the study, clinicians then were asked to palpate pre-identified pairs of vertebrae in an asymptomatic volunteer and to identify the stiffer of the pair (T7 and L3, T7 and L4, L3 and L4), and the biomechanical stiffness of each vertebral pair was quantified objectively by a validated instrument. RESULTS: The mean stiffness detection threshold for the clinicians was 8%. Objective measurement of the stiffness differential between vertebral pairs was 30% for T7* and L3, 20% for T7* and L4, and 10% for L3* and L4 (*denotes the stiffer of the pair). Ten of 12 clinicians correctly identified T7 as stiffer when compared with L3 and T7 as stiffer than L4. Alternatively, when the differential vertebral pair stiffness was similar to the stiffness detection threshold (~8%), clinicians were less successful in identifying the stiffer vertebra of the pair; 4 of 12 clinicians correctly identified L3 as being stiffer compared with L4. CONCLUSION: These results suggest that the physiological limits of human palpation may limit the ability of clinicians to identify small alterations in spine stiffness.

Prevalence and practice characteristics of urban and rural or remote Australian chiropractors: Analysis of a nationally representative sample of 1830 chiropractors.

OBJECTIVE: To determine the prevalence and clinical management characteristics of chiropractors practising in urban and rural or remote Australia. DESIGN: A cross-sectional analysis of the Australian Chiropractic Research Network project data. SETTING: Nationally representative sample of registered chiropractors practising in Australia. PARTICIPANTS: Chiropractors who participated in the Australian Chiropractic Research Network project and answered a question about practising in urban or rural or remote areas in the practitioner questionnaire. MAIN OUTCOME MEASURE: The demographics, practice characteristics and clinical management of chiropractors. RESULTS: The majority of chiropractors indicated that they practise in urban areas only, while 22.8% (n = 435) practice in rural or remote areas only and 4.0% (n = 77) practice in both urban and rural or remote areas. Statistically significant predictors of chiropractors who practice in rural or remote areas, as compared to urban areas, included more patient visits per week, practising in more than one location, no imaging facilities on site, often treating degenerative spinal conditions or migraine, often treating people aged over 65 years, frequently treating Aboriginal and Torres Strait Islander people and frequently using biomechanical pelvic blocking or the sacro-occipital technique. CONCLUSION: A substantial number of chiropractors practice in rural or remote Australia and these rural or remote-based chiropractors are more likely to treat a wide range of musculoskeletal cases and include an Indigenously diverse group of patients than their urban-located colleagues. Unique practice challenges for rural or remote chiropractors include a higher workload and a lack of diagnostic tools. Chiropractors should be acknowledged and considered within rural or remote health care policy and service provision.
