Temporal cell fate determination in the spinal cord is mediated by the duration of Notch signalling.

During neural development, progenitor cells generate different types of neurons in specific time windows. Despite the characterisation of many of the transcription factor networks involved in these differentiation events, the mechanism behind their temporal regulation is poorly understood. To address this question, we studied the temporal differentiation of the simple lateral floor plate (LFP) domain in the zebrafish spinal cord. LFP progenitors generate both early-born Kolmer-Agduhr" (KA") interneuron and late-born V3 interneuron populations. Analysis using a Notch signalling reporter demonstrates that these cell populations have distinct Notch signalling profiles. Not only do V3 progenitors receive higher total levels of Notch response, but they collect this response over a longer duration compared to KA" progenitors. To test whether the duration of Notch signalling determines the temporal cell fate specification, we combined a transgene that constitutively activates Notch signalling in the ventral spinal cord with a heat shock inducible Notch signalling terminator to switch off Notch response at any given time. Sustained Notch signalling results in expanded LFP progenitors while KA" and V3 interneurons fail to specify. Early termination of Notch signalling leads to exclusively KA" cell fate, despite the high level of Notch signalling, whereas late attenuation of Notch signalling drives only V3 cell fate. This suggests that the duration of Notch signalling, not simply the level, mediates cell fate specification. Interestingly, knockdown experiments reveal a role for the Notch ligand Jag2b in maintaining LFP progenitors and limiting their differentiation into KA" and V3 interneurons. Our results indicate that Notch signalling is required for neural progenitor maintenance while a specific attenuation timetable defines the fate of the postmitotic progeny.

Promoting the use of a self-management strategy among novice chiropractors treating individuals with spine pain: A mixed methods pilot clustered-clinical trial.

BACKGROUND: The uptake of Self-Management Support (SMS) among clinicians is suboptimal. To date, few studies have tested knowledge translation (KT) interventions to increase the application of SMS in chiropractic teaching clinics. STUDY OBJECTIVE: Evaluate the feasibility of implementing a KT intervention to promote the use of a SMS strategy among chiropractic interns, their supervisors, and individuals with spine pain compared to controls. METHODS: Mixed methods pilot clustered-clinical trial. Clusters of 16 Patient Management Teams were allocated to a complex KT intervention (online and workshop training). Primary feasibility outcomes for clinicians, interns and patients were rates of recruitment, retention, and adherence to protocol. A nominal group technique and interviews were used to seek end-users' views on the implementation process, and generate possible solutions. RESULTS: In total, 16 (84%) clinicians, 65 (26%) interns and 42 patients agreed to participate. All clinicians in the intervention group completed all KT intervention components, 23 interns (85%) completed the online training and 14 interns (51.8%) attended the workshop training. All clinicians in the intervention and seven (78%) in the control group completed all outcome measures at baseline and 6-month follow-up, while 15 (55.6%) and 23 (60.5%) interns in the intervention and control groups completed the questionnaires at baseline and 6-month follow-up, respectively. Among patients, 10 (52.6%) and 12 (52.2%) in the intervention and control groups respectively completed the questionnaires at the end of the study. Based on interview findings, solutions to improve the feasibility of conducting a full trial include: making SMS a part of the internship, changing the time of introducing the study to the interns, and having more training on SMS. CONCLUSION: Recruitment and retention of chiropractic interns and patients for a larger implementation trial in a single outpatient teaching clinic may be challenging.

The prevalence of anxiety, stress and depressive symptoms in undergraduate students at the Canadian Memorial Chiropractic College.

Objective (1) Determine the one-week prevalence of moderate to extreme symptoms of anxiety, stress and depression in chiropractic undergraduate students. (2) Determine whether the prevalence varies across gender and year of study. Participants: Undergraduate students at the Canadian Memorial Chiropractic College (CMCC). Methods: A cross-sectional study was conducted in fall 2017 to measure self-reported symptoms of anxiety, stress and depression using the DASS-21. Results: The participation rate was 67.0% (510/766). The one-week prevalence of moderate to extreme symptoms was 19.0% (95% CI: 13.0-25.0) for depression; 32.6% (95% CI: 24.7-40.3) for anxiety and 21.8% (95% CI: 15.6-28.1) for stress. The prevalence of stress varied significantly across gender: 25.4% (95% CI: 20.5-30.3) for females versus 16.3% (95% CI: 11.2-21.3) for males. The one-week prevalence of depressive (24.8%; 95% CI: 17.6-32.0) and anxiety (40.9%; 95% CI: 32.6-49.1) symptoms peaked in second year. Conclusions: Self-reported symptoms of anxiety, stress and depression are common in CMCC students.

Intra- and inter-rater reliability of an electronic health record audit used in a chiropractic teaching clinic system: an observational study.

BACKGROUND: There is a dearth of information about health education clinical file audits in the context of completeness of records and demonstrating program-wide competency achievement. We report on the reliability of an audit instrument used for electronic health record (EHR) audits in the clinics of a chiropractic college in Canada. METHODS: The instrument is a checklist built within an electronic software application designed to pull data automatically from the EHR. It consists of a combination of 61 objective (n = 20) and subjective (n = 41) elements, representing domains of standards of practice, accreditation and in-house educational standards. Trained auditors provide responses to the elements and the software yields scores indicating the quality of clinical record per file. A convenience sample of 24 files, drawn randomly from the roster of 22 clinicians, were divided into three groups of eight to be completed by one of three auditors in the span of 1 week, at the end of which they were transferred to another auditor. There were four audit cycles; audits from cycles 1 and 4 were used to assess intra-rater (test-retest) reliability and audits from cycles 1, 2 and 3 were used to assess inter-rater reliability. Percent agreement (PA) and Kappa statistics (K) were used as outcomes. Scatter plots and intraclass correlation (ICC) coefficients were used to assess standards of practice, accreditation, and overall audit scores. RESULTS: Across all 3 auditors test-retest reliability for objective items was PA 89% and K 0.75, and for subjective items PA 82% and K 0.63. In contrast, inter-rater reliability was moderate at PA 82% and K 0.59, and PA 70% and K 0.44 for objective and subjective items, respectively. Element analysis indicated a wide range of PA and K values inter-rater reliability of many elements being rated as poor. ICC coefficient calculations indicated moderate reliability for the domains of standards of practice, accreditation, and overall file scores. CONCLUSION: The file audit process has substantial test-retest reliability and moderate inter-rater reliability. Recommendations are made to improve reliability outcomes. These include modifying the audit checklist with a view of improving clarity of elements, and enhancing uniformity of auditor responses by increased training aided by preparation of an audit guidebook.

Noninvasive management of soft tissue disorders of the shoulder: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) collaboration.

OBJECTIVES: Objective of this study is to develop an evidence-based guideline for the noninvasive management of soft tissue disorders of the shoulder (shoulder pain), excluding major pathology. METHODS: This guideline is based on high-quality evidence from seven systematic reviews. Multidisciplinary experts considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences when formulating recommendations. Target audience is clinicians; target population is adults with shoulder pain. RESULTS: When managing patients with shoulder pain, clinicians should (a) rule out major structural or other pathologies as the cause of shoulder pain and reassure patients about the benign and self-limited nature of most soft tissue shoulder pain; (b) develop a care plan in partnership with the patient; (c) for shoulder pain of any duration, consider low-level laser therapy; multimodal care (heat/cold, joint mobilization, and range of motion exercise); cervicothoracic spine manipulation and mobilization for shoulder pain when associated pain or restricted movement of the cervicothoracic spine; or thoracic spine manipulation; (d) for shoulder pain >3-month duration, consider stretching and/or strengthening exercises; laser acupuncture; or general physician care (information, advice, and pharmacological pain management if necessary); (e) for shoulder pain with calcific tendinitis on imaging, consider shock-wave therapy; (f) for shoulder pain of any duration, do not offer ultrasound; taping; interferential current therapy; diacutaneous fibrolysis; soft tissue massage; or cervicothoracic spine manipulation and mobilization as an adjunct to exercise (i.e., range of motion, strengthening and stretching exercise) for pain between the neck and the elbow at rest or during movement of the arm; (g) for shoulder pain >3-month duration, do not offer shock-wave therapy; and (h) should reassess the patient's status at each visit for worsening of symptoms or new physical, mental, or psychological symptoms, or satisfactory recovery. CONCLUSIONS: Our evidence-based guideline provides recommendations for non-invasive management of shoulder pain. The impact of the guideline in clinical practice requires further evaluation. SIGNIFICANCE: Shoulder pain of any duration can be effectively treated with laser therapy, multimodal care (i.e., heat/cold, joint mobilization, range of motion exercise), or cervicothoracic manipulation and mobilization. Shoulder pain (>3 months) can be effectively treated with exercises, laser acupuncture, or general physician care (information, advice, and pharmacological pain management if necessary).

Complex crosstalk of Notch and Hedgehog signalling during the development of the central nervous system.

The development of the vertebrate central nervous system (CNS) is tightly regulated by many highly conserved cell signalling pathways. These pathways ensure that differentiation and migration events occur in a specific and spatiotemporally restricted manner. Two of these pathways, Notch and Hedgehog (Hh) signalling, have been shown to form a complex web of interaction throughout different stages of CNS development. Strikingly, some processes employ Notch signalling to regulate Hh response, while others utilise Hh signalling to modulate Notch response. Notch signalling functions upstream of Hh response through controlling the trafficking of integral pathway components as well as through modulating protein levels and transcription of downstream transcriptional factors. In contrast, Hh signalling regulates Notch response by either indirectly controlling expression of key Notch ligands and regulatory proteins or directly through transcriptional control of canonical Notch target genes. Here, we review these interactions and demonstrate the level of interconnectivity between the pathways, highlighting context-dependent modes of crosstalk. Since many other developmental signalling pathways are active in these tissues, it is likely that the interplay between Notch and Hh signalling is not only an example of signalling crosstalk but also functions as a component of a wider, multi-pathway signalling network.

Promoting the use of self-management in patients with spine pain managed by chiropractors and chiropractic interns: barriers and design of a theory-based knowledge translation intervention.

Background: The literature supports the effectiveness of self-management support (SMS) to improve health outcomes of patients with chronic spine pain. However, patient engagement in SMS programs is suboptimal. The objectives of this study were to: 1) assess participation in self-care (i.e. activation) among patients with spine pain, 2) identify patients' barriers and enablers to using SMS, and 3) map behaviour change techniques (BCTs) to key barriers to inform the design of a knowledge translation (KT) intervention aimed to increase the use of SMS. Methods: In summer 2016, we invited 250 patients with spine pain seeking care at the Canadian Memorial Chiropractic College in Ontario, Canada to complete the Patient Activation Measure (PAM) survey to assess the level of participation in self-care. We subsequently conducted individual interviews, in summer 2017, based on the Theoretical Domains Framework (TDF) in a subset of patients to identify potential challenges to using SMS. The interview guide included 20 open-ended questions and accompanying probes. Findings were deductively analysed guided by the TDF. A panel of 7 experts mapped key barriers to BCTs, designed a KT intervention, and selected the modes of delivery. Results: Two hundred and twenty-three patients completed the PAM. Approximately 24% of respondents were not actively involved in their care. Interview findings from 13 spine pain patients suggested that the potential barriers to using SMS corresponded to four TDF domains: Environmental Context and Resources; Emotion; Memory, Attention & Decision-Making; and Behavioural Regulation. The proposed theory-based KT intervention includes paper-based educational materials, webinars and videos, summarising and demonstrating the therapeutic recommendations including exercises and other lifestyle changes. In addition, the KT intervention includes Brief Action Planning, a SMS strategy based on motivational interviewing, along with a SMART plan and reminders. Conclusions: Almost one quarter of study participants were not actively engaged in their spine care. Key barriers likely to influence uptake of SMS among patients were identified and used to inform the design of a theory-based KT intervention to increase their participation level. The proposed multi-component KT intervention may be an effective strategy to optimize the quality of spine pain care and improve patients' health-outcomes.

Notch signalling maintains Hedgehog responsiveness via a Gli-dependent mechanism during spinal cord patterning in zebrafish.

Spinal cord patterning is orchestrated by multiple cell signalling pathways. Neural progenitors are maintained by Notch signalling, whereas ventral neural fates are specified by Hedgehog (Hh) signalling. However, how dynamic interactions between Notch and Hh signalling drive the precise pattern formation is still unknown. We applied the PHRESH (PHotoconvertible REporter of Signalling History) technique to analyse cell signalling dynamics in vivo during zebrafish spinal cord development. This approach reveals that Notch and Hh signalling display similar spatiotemporal kinetics throughout spinal cord patterning. Notch signalling functions upstream to control Hh response of neural progenitor cells. Using gain- and loss-of-function tools, we demonstrate that this regulation occurs not at the level of upstream regulators or primary cilia, but rather at the level of Gli transcription factors. Our results indicate that Notch signalling maintains Hh responsiveness of neural progenitors via a Gli-dependent mechanism in the spinal cord.

Non-pharmacological management of persistent headaches associated with neck pain: A clinical practice guideline from the Ontario protocol for traffic injury management (OPTIMa) collaboration.

OBJECTIVES: To develop an evidence-based guideline for the non-pharmacological management of persistent headaches associated with neck pain (i.e., tension-type or cervicogenic). METHODS: This guideline is based on systematic reviews of high-quality studies. A multidisciplinary expert panel considered the evidence of clinical benefits, cost-effectiveness, societal and ethical values, and patient experiences when formulating recommendations. Target audience includes clinicians; target population is adults with persistent headaches associated with neck pain. RESULTS: When managing patients with headaches associated with neck pain, clinicians should (a) rule out major structural or other pathologies, or migraine as the cause of headaches; (b) classify headaches associated with neck pain as tension-type headache or cervicogenic headache once other sources of headache pathology has been ruled out; (c) provide care in partnership with the patient and involve the patient in care planning and decision making; (d) provide care in addition to structured patient education; (e) consider low-load endurance craniocervical and cervicoscapular exercises for tension-type headaches (episodic or chronic) or cervicogenic headaches >3 months duration; (f) consider general exercise, multimodal care (spinal mobilization, craniocervical exercise and postural correction) or clinical massage for chronic tension-type headaches; (g) do not offer manipulation of the cervical spine as the sole form of treatment for episodic or chronic tension-type headaches; (h) consider manual therapy (manipulation with or without mobilization) to the cervical and thoracic spine for cervicogenic headaches >3 months duration. However, there is no added benefit in combining spinal manipulation, spinal mobilization and exercises; and (i) reassess the patient at every visit to assess outcomes and determine whether a referral is indicated. CONCLUSIONS: Our evidence-based guideline provides recommendations for the conservative management of persistent headaches associated with neck pain. The impact of the guideline in clinical practice requires validation. SIGNIFICANCE: Neck pain and headaches are very common comorbidities in the population. Tension-type and cervicogenic headaches can be treated effectively with specific exercises. Manual therapy can be considered as an adjunct therapy to exercise to treat patients with cervicogenic headaches. The management of tension-type and cervicogenic headaches should be patient-centred.

Is a government-regulated rehabilitation guideline more effective than general practitioner education or preferred-provider rehabilitation in promoting recovery from acute whiplash-associated disorders? A pragmatic randomised controlled trial.

OBJECTIVE: To evaluate the effectiveness of a government-regulated rehabilitation guideline compared with education and activation by general practitioners, and to a preferred-provider insurance-based rehabilitation programme on self-reported global recovery from acute whiplash-associated disorders (WAD) grade I-II. DESIGN: Pragmatic randomised clinical trial with blinded outcome assessment. SETTING: Multidisciplinary rehabilitation clinics and general practitioners in Ontario, Canada. PARTICIPANTS: 340 participants with acute WAD grade I and II. Potential participants were sampled from a large automobile insurer when reporting a traffic injury. INTERVENTIONS: Participants were randomised to receive one of three protocols: government-regulated rehabilitation guideline, education and activation by general practitioners or a preferred-provider insurance-based rehabilitation. PRIMARY AND SECONDARY OUTCOME MEASURES: Our primary outcome was time to self-reported global recovery. Secondary outcomes included time on insurance benefits, neck pain intensity, whiplash-related disability, health-related quality of life and depressive symptomatology at 6 weeks and 3, 6, 9 and 12 months postinjury. RESULTS: The median time to self-reported global recovery was 59 days (95% CI 55 to 68) for the government-regulated guideline group, 105 days (95% CI 61 to 126) for the preferred-provider group and 108 days (95% CI 93 to 206) for the general practitioner group; the difference was not statistically significant (Χ2=3.96; 2 df: p=0.138). We found no clinically important differences between groups in secondary outcomes. Post hoc analysis suggests that the general practitioner (hazard rate ratio (HRR)=0.51, 95% CI 0.34 to 0.77) and preferred-provider groups (HRR=0.67, 95% CI 0.46 to 0.96) had slower recovery than the government-regulated guideline group during the first 80 days postinjury. No major adverse events were reported. CONCLUSIONS: Time-to-recovery did not significantly differ across intervention groups. We found no differences between groups with regard to neck-specific outcomes, depression and health-related quality of life. TRIAL REGISTRATION NUMBER: NCT00546806.

Stereotypic generation of axial tenocytes from bipartite sclerotome domains in zebrafish.

Development of a functional musculoskeletal system requires coordinated generation of muscles, bones, and tendons. However, how axial tendon cells (tenocytes) are generated during embryo development is still poorly understood. Here, we show that axial tenocytes arise from the sclerotome in zebrafish. In contrast to mouse and chick, the zebrafish sclerotome consists of two separate domains: a ventral domain and a previously undescribed dorsal domain. While dispensable for sclerotome induction, Hedgehog (Hh) signaling is required for the migration and maintenance of sclerotome derived cells. Axial tenocytes are located along the myotendinous junction (MTJ), extending long cellular processes into the intersomitic space. Using time-lapse imaging, we show that both sclerotome domains contribute to tenocytes in a dynamic and stereotypic manner. Tenocytes along a given MTJ always arise from the sclerotome of the adjacent anterior somite. Inhibition of Hh signaling results in loss of tenocytes and enhanced sensitivity to muscle detachment. Together, our work shows that axial tenocytes in zebrafish originate from the sclerotome and are essential for maintaining muscle integrity.

Promoting the use of self-management in novice chiropractors treating individuals with spine pain: the design of a theory-based knowledge translation intervention.

BACKGROUND: Clinical practice guidelines generally recommend clinicians use self-management support (SMS) when managing patients with spine pain. However, even within the educational setting, the implementation of SMS remains suboptimal. The objectives of this study were to 1) estimate the organizational readiness for change toward using SMS at the Canadian Memorial Chiropractic College (CMCC), Toronto, Ontario from the perspective of directors and deans, 2) estimate the attitudes and self-reported behaviours towards using evidence-based practice (EBP), and beliefs about pain management among supervisory clinicians and chiropractic interns, 3) identify potential barriers and enablers to using SMS, and 4) design a theory-based tailored Knowledge Translation (KT) intervention to increase the use of SMS. METHODS: Mixed method design. We administered three self-administered questionnaires to assess clinicians' and interns' attitudes and behaviours toward EBP, beliefs about pain management, and practice style. In addition, we conducted 3 focus groups with clinicians and interns based on the Theoretical Domain Framework (TDF) to explore their beliefs about using SMS for patients with spine pain. Data were analysed using deductive thematic analysis by 2 independent assessors. A panel of 7 experts mapped behaviour change techniques to key barriers identified informing the design of a KT intervention. RESULTS: Participants showed high level of EBP knowledge, positive attitude of EBP, and moderate frequency of EBP use. A number of barrier factors were identified from clinicians (N = 6) and interns (N = 16) corresponding to 7 TDF domains: Knowledge; Skills; Environmental context and resources; Emotion; Beliefs about Capabilities; Memory, attention & decision making; and Social Influence. To address these barriers, the expert panel proposed a multifaceted KT intervention composed of a webinar and online educational module on a SMS guided by the Brief Action Planning, clinical vignettes, training workshop, and opinion leader support. CONCLUSION: SMS strategies can help maximizing the health care services for patients with spine pain. This may in turn optimize patients' health. The proposed theory-based KT intervention may facilitate the implementation of SMS among clinicians and interns.

Musculoskeletal Injury in Professional Dancers: Prevalence and Associated Factors: An International Cross-Sectional Study.

OBJECTIVE: The purpose of the study was to determine the prevalence and factors associated with injury in professional ballet and modern dancers, and assess if dancers are reporting their injuries and explore reasons for not reporting injuries. DESIGN: Cross-sectional study. SETTING: Participants were recruited from nine professional ballet and modern dance companies in Canada, Denmark, Israel, and Sweden. PARTICIPANTS: Professional ballet and modern dancers. INDEPENDENT VARIABLES: Sociodemographic variables included age, sex, height, weight, and before-tax yearly or monthly income. Dance specific characteristics included number of years in present dance company, number of years dancing professionally, number of years dancing total, and rank in the company. MAIN OUTCOME MEASURES: Self-reported injury and Self-Estimated Functional Inability because of Pain. RESULTS: A total of 260 dancers participated in the study with an overall response rate of 81%. The point prevalence of self-reported injury in professional ballet and modern dancers was 54.8% (95% CI, 47.7-62.1) and 46.3% (95% CI, 35.5-57.1), respectively. Number of years dancing professionally (OR = 4.4, 95% CI, 1.6-12.3) and rank (OR = 2.4, 95% CI, 1.2-4.8) were associated with injury in ballet dancers. More than 15% of all injured dancers had not reported their injury and their reasons for not reporting injury varied. CONCLUSIONS: The prevalence of injury is high in professional dancers with a significant percentage not reporting their injuries for a variety of reasons. Number of years dancing and rank are associated with injury in professional ballet dancers.

Are Passive Physical Modalities Effective for the Management of Common Soft Tissue Injuries of the Elbow?: A Systematic Review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

OBJECTIVE: To evaluate the effectiveness of passive physical modalities for the management of soft tissue injuries of the elbow. METHODS: We systematically searched MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane Central Register of Controlled Trials from 1990 to 2015. Studies meeting our selection criteria were eligible for critical appraisal. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. We included studies with a low risk of bias in our best evidence synthesis. RESULTS: We screened 6618 articles; 21 were eligible for critical appraisal and 9 (reporting on 8 randomized controlled trials) had a low risk of bias. All randomized controlled trials with a low risk of bias focused on lateral epicondylitis. We found that adding transcutaneous electrical nerve stimulation to primary care does not improve the outcome of patients with lateral epicondylitis. We found inconclusive evidence for the effectiveness of: (1) an elbow brace for managing lateral epicondylitis of variable duration; and (2) shockwave therapy or low-level laser therapy for persistent lateral epicondylitis. DISCUSSION: Our review suggests that transcutaneous electrical nerve stimulation provides no added benefit to patients with lateral epicondylitis. The effectiveness of an elbow brace, shockwave therapy, or low-level laser therapy for the treatment of lateral epicondylitis is inconclusive. We found little evidence to inform the use of passive physical modalities for the management of elbow soft tissue injuries.

Management of neck pain and associated disorders: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

PURPOSE: To develop an evidence-based guideline for the management of grades I-III neck pain and associated disorders (NAD). METHODS: This guideline is based on recent systematic reviews of high-quality studies. A multidisciplinary expert panel considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences (obtained from qualitative research) when formulating recommendations. Target audience includes clinicians; target population is adults with grades I-III NAD <6 months duration. RECOMMENDATION 1: Clinicians should rule out major structural or other pathologies as the cause of NAD. Once major pathology has been ruled out, clinicians should classify NAD as grade I, II, or III. RECOMMENDATION 2: Clinicians should assess prognostic factors for delayed recovery from NAD. RECOMMENDATION 3: Clinicians should educate and reassure patients about the benign and self-limited nature of the typical course of NAD grades I-III and the importance of maintaining activity and movement. Patients with worsening symptoms and those who develop new physical or psychological symptoms should be referred to a physician for further evaluation at any time during their care. RECOMMENDATION 4: For NAD grades I-II ≤3 months duration, clinicians may consider structured patient education in combination with: range of motion exercise, multimodal care (range of motion exercise with manipulation or mobilization), or muscle relaxants. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, strain-counterstrain therapy, relaxation massage, cervical collar, electroacupuncture, electrotherapy, or clinic-based heat. RECOMMENDATION 5: For NAD grades I-II >3 months duration, clinicians may consider structured patient education in combination with: range of motion and strengthening exercises, qigong, yoga, multimodal care (exercise with manipulation or mobilization), clinical massage, low-level laser therapy, or non-steroidal anti-inflammatory drugs. In view of evidence of no effectiveness, clinicians should not offer strengthening exercises alone, strain-counterstrain therapy, relaxation massage, relaxation therapy for pain or disability, electrotherapy, shortwave diathermy, clinic-based heat, electroacupuncture, or botulinum toxin injections. RECOMMENDATION 6: For NAD grade III ≤3 months duration, clinicians may consider supervised strengthening exercises in addition to structured patient education. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, cervical collar, low-level laser therapy, or traction. RECOMMENDATION 7: For NAD grade III >3 months duration, clinicians should not offer a cervical collar. Patients who continue to experience neurological signs and disability more than 3 months after injury should be referred to a physician for investigation and management. RECOMMENDATION 8: Clinicians should reassess the patient at every visit to determine if additional care is necessary, the condition is worsening, or the patient has recovered. Patients reporting significant recovery should be discharged.

The Effectiveness of Multimodal Care for the Management of Soft Tissue Injuries of the Shoulder: A Systematic Review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

OBJECTIVE: The purpose of this systematic review was to evaluate the effectiveness of multimodal care for the management of soft tissue injuries of the shoulder. METHODS: We conducted a systematic review and searched MEDLINE, EMBASE, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials from 1990 to 2015. Two independent reviewers critically appraised studies using the Scottish Intercollegiate Guidelines Network criteria. We used best evidence synthesis to synthesize evidence from studies with low risk of bias. RESULTS: We screened 5885 articles, and 19 were eligible for critical appraisal. Ten randomized controlled trials had low risk of bias. For persistent subacromial impingement syndrome, multimodal care leads to similar outcomes as sham therapy, radial extracorporeal shock-wave therapy, or surgery. For subacromial impingement syndrome, multimodal care may be associated with small and nonclinically important improvement in pain and function compared with corticosteroid injections. For rotator cuff tendinitis, dietary-based multimodal care may be more effective than conventional multimodal care (exercise, soft tissue and manual therapy, and placebo tablets). For nonspecific shoulder pain, multimodal care may be more effective than wait list or usual care by a general practitioner, but it leads to similar outcomes as exercise or corticosteroid injections. CONCLUSIONS: The current evidence suggests that combining multiple interventions into 1 program of care does not lead to superior outcomes for patients with subacromial impingement syndrome or nonspecific shoulder pain. One randomized controlled trial suggested that dietary-based multimodal care (dietary advice, acupuncture, and enzyme tablets) may provide better outcomes over conventional multimodal care. However, these results need to be replicated.

Are non-invasive interventions effective for the management of headaches associated with neck pain? An update of the Bone and Joint Decade Task Force on Neck Pain and Its Associated Disorders by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

PURPOSE: To update findings of the 2000-2010 Bone and Joint Decade Task Force on Neck Pain and its Associated Disorders and evaluate the effectiveness of non-invasive and non-pharmacological interventions for the management of patients with headaches associated with neck pain (i.e., tension-type, cervicogenic, or whiplash-related headaches). METHODS: We searched five databases from 1990 to 2015 for randomized controlled trials (RCTs), cohort studies, and case-control studies comparing non-invasive interventions with other interventions, placebo/sham, or no interventions. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria to determine scientific admissibility. Studies with a low risk of bias were synthesized following best evidence synthesis principles. RESULTS: We screened 17,236 citations, 15 studies were relevant, and 10 had a low risk of bias. The evidence suggests that episodic tension-type headaches should be managed with low load endurance craniocervical and cervicoscapular exercises. Patients with chronic tension-type headaches may also benefit from low load endurance craniocervical and cervicoscapular exercises; relaxation training with stress coping therapy; or multimodal care that includes spinal mobilization, craniocervical exercises, and postural correction. For cervicogenic headaches, low load endurance craniocervical and cervicoscapular exercises; or manual therapy (manipulation with or without mobilization) to the cervical and thoracic spine may also be helpful. CONCLUSIONS: The management of headaches associated with neck pain should include exercise. Patients who suffer from chronic tension-type headaches may also benefit from relaxation training with stress coping therapy or multimodal care. Patients with cervicogenic headache may also benefit from a course of manual therapy.

Are manual therapies, passive physical modalities, or acupuncture effective for the management of patients with whiplash-associated disorders or neck pain and associated disorders? An update of the Bone and Joint Decade Task Force on Neck Pain and Its Associated Disorders by the OPTIMa collaboration.

BACKGROUND CONTEXT: In 2008, the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders (Neck Pain Task Force) found limited evidence on the effectiveness of manual therapies, passive physical modalities, or acupuncture for the management of whiplash-associated disorders (WAD) or neck pain and associated disorders (NAD). PURPOSE: This review aimed to update the findings of the Neck Pain Task Force, which examined the effectiveness of manual therapies, passive physical modalities, and acupuncture for the management of WAD or NAD. STUDY DESIGN/SETTING: This is a systematic review and best evidence synthesis. SAMPLE: The sample includes randomized controlled trials, cohort studies, and case-control studies comparing manual therapies, passive physical modalities, or acupuncture with other interventions, placebo or sham, or no intervention. OUTCOME MEASURES: The outcome measures were self-rated or functional recovery, pain intensity, health-related quality of life, psychological outcomes, or adverse events. METHODS: We systematically searched five databases from 2000 to 2014. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Studies with a low risk of bias were stratified by the intervention's stage of development (exploratory vs. evaluation) and synthesized following best evidence synthesis principles. Funding was provided by the Ministry of Finance. RESULTS: We screened 8,551 citations, and 38 studies were relevant and 22 had a low risk of bias. Evidence from seven exploratory studies suggests that (1) for recent but not persistent NAD grades I-II, thoracic manipulation offers short-term benefits; (2) for persistent NAD grades I-II, technical parameters of cervical mobilization (eg, direction or site of manual contact) do not impact outcomes, whereas one session of cervical manipulation is similar to Kinesio Taping; and (3) for NAD grades I-II, strain-counterstrain treatment is no better than placebo. Evidence from 15 evaluation studies suggests that (1) for recent NAD grades I-II, cervical and thoracic manipulation provides no additional benefit to high-dose supervised exercises, and Swedish or clinical massage adds benefit to self-care advice; (2) for persistent NAD grades I-II, home-based cupping massage has similar outcomes to home-based muscle relaxation, low-level laser therapy (LLLT) does not offer benefits, Western acupuncture provides similar outcomes to non-penetrating placebo electroacupuncture, and needle acupuncture provides similar outcomes to sham-penetrating acupuncture; (3) for WAD grades I-II, needle electroacupuncture offers similar outcomes as simulated electroacupuncture; and (4) for recent NAD grades III, a semi-rigid cervical collar with rest and graded strengthening exercises lead to similar outcomes, and LLLT does not offer benefits. CONCLUSIONS: Our review adds new evidence to the Neck Pain Task Force and suggests that mobilization, manipulation, and clinical massage are effective interventions for the management of neck pain. It also suggests that electroacupuncture, strain-counterstrain, relaxation massage, and some passive physical modalities (heat, cold, diathermy, hydrotherapy, and ultrasound) are not effective and should not be used to manage neck pain.

The Effectiveness of Noninvasive Interventions for Temporomandibular Disorders: A Systematic Review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

OBJECTIVE: To determine the effectiveness and cost-effectiveness of noninvasive interventions for temporomandibular disorders (TMD). METHODS: We systematically searched MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane Central register from 1990 to 2014 for effectiveness studies and the Cochrane Health Technology Assessment Database, EconLit, NHS Economic Evaluation Database, and Tufts Medical Center Cost-Effectiveness Analysis Register from 1990 to 2014 for cost-effectiveness studies. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Evidence from eligible studies was synthesized using best-evidence synthesis methodology. RESULTS: Our search for effectiveness studies yielded 16,995 citations; 31 were relevant and 7 randomized controlled trials (published in 8 articles) had a low risk of bias. We found no relevant cost-effectiveness studies. The evidence suggests that for persistent TMD: (1) cognitive-behavioral therapy and self-care management lead to similar improvements in pain and disability but cognitive-behavioral therapy is more effective for activity interference and depressive symptoms; (2) cognitive-behavioral therapy combined with usual treatment provides short-term benefits in pain and ability to control pain compared with usual treatment alone; (3) intraoral myofascial therapy may reduce pain and improve jaw opening; and (4) structured self-care management may be more effective than usual treatment. The evidence suggests that occlusal devices may not be effective in reducing pain and improving motion for TMD of variable duration. Evidence on the effectiveness of biofeedback is inconclusive. DISCUSSION: The available evidence suggests that cognitive-behavioral therapy, intraoral myofascial therapy, and self-care management are therapeutic options for persistent TMD.

Does structured patient education improve the recovery and clinical outcomes of patients with neck pain? A systematic review from the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

BACKGROUND CONTEXT: In 2008, the Bone and Joint Decade 2000 to 2010 Task Force on Neck Pain and Its Associated Disorders recommended patient education for the management of neck pain. However, the effectiveness of education interventions has recently been challenged. PURPOSE: To update the findings of the Bone and Joint Decade 2000 to 2010 Task Force on Neck Pain and Its Associated Disorders and evaluate the effectiveness of structured patient education for the management of patients with whiplash-associated disorders (WAD) or neck pain and associated disorders (NAD). STUDY DESIGN/SETTING: Systematic review of the literature and best-evidence synthesis. PATIENT SAMPLE: Randomized controlled trials that compared structured patient education with other conservative interventions. OUTCOME MEASURES: Self-rated recovery, functional recovery (eg, disability, return to activities, work, or school), pain intensity, health-related quality of life, psychological outcomes such as depression or fear, or adverse effects. METHODS: We systematically searched eight electronic databases (MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Central Register of Controlled Trials, DARE, PubMed, and ICL) from 2000 to 2012. Randomized controlled trials, cohort studies, and case-control studies meeting our selection criteria were eligible for critical appraisal. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Scientifically admissible studies were summarized in evidence tables and synthesized following best-evidence synthesis principles. RESULTS: We retrieved 4,477 articles. Of those, nine were eligible for critical appraisal and six were scientifically admissible. Four admissible articles investigated patients with WAD and two targeted patients with NAD. All structured patient education interventions included advice on activation or exercises delivered orally combined with written information or as written information alone. Overall, as a therapeutic intervention, structured patient education was equal or less effective than other conservative treatments including massage, supervised exercise, and physiotherapy. However, structured patient education may provide small benefits when combined with physiotherapy. Either mode of delivery (ie, oral or written education) provides similar results in patients with recent WAD. CONCLUSIONS: This review adds to the Bone and Joint Decade 2000 to 2010 Task Force on Neck Pain and Its Associated Disorders by defining more specifically the role of structured patient education in the management of WAD and NAD. Results suggest that structured patient education alone cannot be expected to yield large benefits in clinical effectiveness compared with other conservative interventions for patients with WAD or NAD. Moreover, structured patient education may be of benefit during the recovery of patients with WAD when used as an adjunct therapy to physiotherapy or emergency room care. These benefits are small and short lived.
