Knee and hip osteoarthritis (OA) place a significant burden on the Canadian health system and are a major public health challenge. This brief commentary discusses the recently published Osteoarthritis Research Society International guideline and the American College of Rheumatology guideline for the management of OA. Special attention has been given to the role of manual therapy, exercise, and patient education for the treatment of knee and hip OA. This article also reviews the Good Life with osteoArthritis in Denmark (GLA:D^®) treatment program for knee and hip OA and the implementation of this program in Canada. Lastly, the authors discuss the opportunity for the Canadian chiropractic profession to embrace treatment programs like GLA:D^® and take an active role in the strengthening of the Canadian health system from a musculoskeletal perspective.

Background: The purpose of this study is to update a previous critical review of adverse events in pregnant and postpartum populations.

Methods: The following databases were searched: PubMed, CINAHL, Index to Chiropractic Literature, Cochrane Database of Systematic Reviews/Cochrane Central Register of Controlled Trials and MEDLINE. We included all study design types as it was determined a priori that there would not be enough high-quality research on spinal manipulative therapy (SMT) in these populations to make any determinations. The Scottish Intercollegiate Guidelines Network (SIGN) and CARE (CAse REport) checklists were used for quality rating.

Results: This update found one case study that demonstrated a serious adverse event in the cervical spine following SMT and a handful of minor and transient adverse events in the low back following SMT.

Conclusions: There was limited evidence of adverse events following SMT in these populations. Although we are calling for improved reporting of such events in future studies, it may be that such injuries are rare.

Introduction: The objective of this study was to survey 2018-2019 Year III students at the Canadian Memorial Chiropractic College in order explore their perceptions of the components of the revised Jurisprudence, Ethics and Business Management course.

Methods: This study was approved by the Research Ethics Board. A paper survey was distributed to all enrolled students. Using a five-point Likert scale, students were asked if they perceived the course material was (i) well-presented and (ii) important for them to know as future chiropractors. Students were required to sign a consent form to participate.

Results: Survey response rate was 94%. Over 90% of respondents 'strongly agreed/'agreed' lectures, small group session and course assignments were well presented and important for them to know as future chiropractors. Respondents were more critical of the online business modules (on average, 50% 'strongly agreed/agreed').

Conclusions: The information from this survey will enable refinement of future versions of this course.

Objective: To describe the case of a 21-year-old female with previously diagnosed neurofibromatosis type 1 (NF1) with neck, scapular, lumbar, and temporomandibular discomfort along with headaches.

Clinical features: The patient had chronic tightness and pain in the cervicothoracic region as well as pain in the lumbar spine at the site of prior neurofibroma removal. Radiographs demonstrated multilevel osseous changes. In addition to NF-1, she was diagnosed with cervical myalgia, tension-type headaches, and chronic temporomandibular joint disorder.

Intervention and outcomes: Treatment consisted of a course of manual therapy including cervical flexiondistraction, myofascial release, patient education on workplace ergonomics, and an at-home active care plan. The patient experienced a reduction in pain and headache frequency.

Summary: Manual therapy in the form of cervical flexion-distraction with myofascial release and education on workplace ergonomics were effective in reducing neck and thoracic pain as well as reducing headache frequency in a 21-year-old with NF-1.

Objective: Kappa (κ) light chain multiple myeloma can be disguised as low back pain (LBP), and as such may present to a primary contact provider such as a chiropractor. The rarity and non-specific nature of the clinical presentation of this condition typically lead to a delayed diagnosis.

Case presentation: A 53-year old male avid golfer presented to a chiropractor with a chief complaint of LBP. He was diagnosed with sacroiliac joint dysfunction. His pain was initially improving with chiropractic management. The character of his pain changed, and the chiropractor referred for further imaging. He was subsequently diagnosed with κ light chain multiple myeloma.

Summary: This case presentation highlights that spinal malignancy is a possible cause of LBP. It reminds the clinician to investigate signs and symptoms that could lead to a suspicion of malignancy, to monitor patient progression, and consider further evaluations if the expected response to treatment is not achieved.

Objective: To determine the incidence and risk factors of musculoskeletal disorders of the elbow in baseball pitchers.

Design: Systematic review.

Data sources: Medline, CINAHL, Cochrane, PubMed and SportDiscus from onset to July 7, 2018.

Eligibility criteria: Eligible studies included randomized controlled trials, cohort studies and case-control studies. Independent pairs of reviewers screened titles and abstracts for eligibility. Relevant articles were critically appraised for internal validity using the SIGN criteria. We included low risk of bias studies in our best evidence synthesis.

Results: We retrieved 4502 articles, 39 were critically appraised and nine had a low risk of bias. These were included in the evidence synthesis. The incidence of musculoskeletal disorders of the elbow ranges from 2.3% in adolescent pitchers to 40.6% in youth pitchers. Evidence suggests that pitch characteristics, inadequate rest, biomechanical and anthropometric factors may be risk factors of UCL tears.

Summary/conclusion: Baseball pitchers develop musculoskeletal disorders of the elbow. There is little high-quality evidence to understand the etiology. Preliminary evidence suggests the risk factors are multifactorial.PROSPERO Trial Registration Number: CRD42018092081.

Background: In 2015, the U.S. Soccer Federation banned heading for players aged 10-13.

Purpose/question: To assess the change in proportion of children aged 10-13 playing soccer in the US presenting to an Emergency Department (ED) with a concussion in relation to any other injury before and after the ban.

Methods: Analysis was restricted to soccer athletes between 10-13 years that reported to a National Electronic Injury Surveillance System (NEISS) participating hospital ED following injury in 2013-2014 and 2016-2017. Multivariable logistic regression was performed to assess the association between year of injury and concussion diagnosis in relation to other injury diagnosis after adjusting for age, sex, and ethnicity.

Results: Concussion in relation to other injuries showed a significant increase in 2016-2017 when compared to 2013-2014 after adjustment (OR= 1.286, 95%CI = 1.090-1.517).

Conclusions: These results suggest that banning heading may not reduce concussion within this population. However, significant confounders, including increased reporting, were not controlled for.

Background: Whilst half of all Australian chiropractors report often treating athletes, there is insufficient evidence to characterise the sports chiropractor in Australia.

Objective: To perform a workforce survey of Sports Chiropractic Australia (SCA) members.

Methods: A 74-item web-based questionnaire collected information about practitioner and practice characteristics. Descriptive statistics summarised practitioner and patient characteristics, caseload and management approaches.

Results: SCA members were predominantly male (74%) with 11.3 (±8.4) years of clinical experience. Amateur or semi-professional sportspeople comprised 67% of SCA members' caseload. Athletes were most likely to present with a lower limb musculoskeletal condition (44%), followed by low back pain (34%). Nearly half (43%) of musculoskeletal conditions were co-managed with another healthcare practitioner.

Conclusions: SCA members provided care for people of all sporting abilities, ranging from recreational to elite athletes, but most typically at the non-elite level. SCA members almost exclusively treat musculoskeletal conditions and apply various modalities in the management of athletes and sportspeople.

Objective: To evaluate the test-retest reliability and construct validity of the concussion knowledge assessment tool (CKAT) as a measure of knowledge of concussion and its management among chiropractic subgroups and to compare these properties for two scoring strategies for the CKAT.

Methods: Three chiropractic subgroups (first year students, interns and sports chiropractors) completed the CKAT via SurveyMonkey with as second administration two to six weeks later for a subset of respondents. Scatter plots and Intraclass Correlation Coefficients (ICC) were used for test-retest reliability. A priori hypotheses regarding the relationship of CKAT scores across known subgroups, and with concussion knowledge self-rankings were established prior to data collection. Distributions of CKAT scores were compared across the subgroups using boxplots and ANOVA for known groups validity, and correlation of CKAT scores with concussion knowledge self-ranking was examined.

Results: Test-retest ICC for the revised scoring was 0.68 (95%CI 0.51-0.80). First year students had a mean revised CKAT (out of 49) of 36.9 (SD= 4.7), interns 39.9 (SD=3.0) and sports chiropractors 41.8 (SD=3.2) which are significantly different (F_2,125=17.54; p<0.0001).

Conclusions: The CKAT distinguished between chiropractic subgroups expected to have different levels of knowledge, supporting construct validity, however, it did not achieve adequate test-retest reliability.
