Exploring 1st- and 2nd-year chiropractic students' willingness and attitudes toward peer physical examination

Objective This study aimed to explore chiropractic students' perceptions and attitudes about the appropriateness of peer physical examination as a teaching tool and their willingness and comfort with it. Methods A modified version of a validated questionnaire was used. First- and 2nd-year chiropractic students at Murdoch University were approached during their practical sessions. The responses were analyzed using descriptive statistics reporting frequencies and percentages. Comparison between classes, age, and sex was evaluated by cross-tabulation. Results A total of 184 questionnaires were completed with a response rate of 76.6%. Our results demonstrated that most students were comfortable with and willing to participate in peer physical examination as well as trusted it as an appropriate part of their training and a valuable learning experience. Nevertheless, a small percentage were uncomfortable with peer physical examination and regarded it as an unprofessional activity. In addition, it was revealed that younger females (≤20 years) reported feeling unnecessarily exposed and therefore significantly less comfortable with peer physical examination. They were also less comfortable when examined in the inguinal area by a student of the opposite sex. Conclusion Although peer physical examination appears to be a very popular training tool, it still has a few areas of concern that need to be investigated and addressed to improve students' attitude, perception, and comfort with this teaching technique. Further studies could investigate how other factors such as religious beliefs contribute toward students' perception and attitudes regarding peer physical examination

Spinal degeneration is associated with lumbar multifidus morphology in secondary care patients with low back or leg pain

Associations between multifidus muscle morphology and degenerative pathologies have been implied in patients with non-specific low back pain, but it is unknown how these are influenced by pathology severity, number, or distribution. MRI measures of pure multifidus muscle cross-sectional area (CSA) were acquired from 522 patients presenting with low back and/or leg symptoms in an outpatient clinic. We explored cross-sectional associations between the presence, distribution, and/or severity of lumbar degenerative pathologies (individually and in aggregate) and muscle outcomes in multivariable analyses (beta coefficients [95% CI]). We identified associations between lower pure multifidus muscle CSA and disc degeneration (at two or more levels): − 4.51 [− 6.72; − 2.3], Modic 2 changes: − 4.06 [− 6.09; − 2.04], endplate defects: − 2.74 [− 4.58; − 0.91], facet arthrosis: − 4.02 [− 6.26; − 1.78], disc herniations: − 3.66 [− 5.8; − 1.52], and when > 5 pathologies were present: − 6.77 [− 9.76; − 3.77], with the last supporting a potential dose–response relationship between number of spinal pathologies and multifidus morphology. Our findings could hypothetically indicate that these spinal and muscle findings: (1) are part of the same degenerative process, (2) result from prior injury or other common antecedent events, or (3) have a directional relationship. Future longitudinal studies are needed to further examine the complex nature of these relationships

Amyloid and tau pathology associations with personality traits, neuropsychiatric symptoms, and cognitive lifestyle in the preclinical phases of sporadic and autosomal dominant Alzheimer’s disease

Background Major prevention trials for Alzheimer’s disease (AD) are now focusing on multidomain lifestyle interventions. However, the exact combination of behavioral factors related to AD pathology remains unclear. In 2 cohorts of cognitively unimpaired individuals at risk of AD, we examined which combinations of personality traits, neuropsychiatric symptoms, and cognitive lifestyle (years of education or lifetime cognitive activity) related to the pathological hallmarks of AD, amyloid-β, and tau deposits. Methods A total of 115 older adults with a parental or multiple-sibling family history of sporadic AD (PREVENT-AD [PRe-symptomatic EValuation of Experimental or Novel Treatments for AD] cohort) underwent amyloid and tau positron emission tomography and answered several questionnaires related to behavioral attributes. Separately, we studied 117 mutation carriers from the DIAN (Dominant Inherited Alzheimer Network) study group cohort with amyloid positron emission tomography and behavioral data. Using partial least squares analysis, we identified latent variables relating amyloid or tau pathology with combinations of personality traits, neuropsychiatric symptoms, and cognitive lifestyle. Results In PREVENT-AD, lower neuroticism, neuropsychiatric burden, and higher education were associated with less amyloid deposition (p = .014). Lower neuroticism and neuropsychiatric features, along with higher measures of openness and extraversion, were related to less tau deposition (p = .006). In DIAN, lower neuropsychiatric burden and higher education were also associated with less amyloid (p = .005). The combination of these factors accounted for up to 14% of AD pathology. Conclusions In the preclinical phase of both sporadic and autosomal dominant AD, multiple behavioral features were associated with AD pathology. These results may suggest potential pathways by which multidomain interventions might help delay AD onset or progression

A united statement of the global chiropractic research community against the pseudoscientific claim that chiropractic care boosts immunity.

BACKGROUND: In the midst of the coronavirus pandemic, the International Chiropractors Association (ICA) posted reports claiming that chiropractic care can impact the immune system. These claims clash with recommendations from the World Health Organization and World Federation of Chiropractic. We discuss the scientific validity of the claims made in these ICA reports. MAIN BODY: We reviewed the two reports posted by the ICA on their website on March 20 and March 28, 2020. We explored the method used to develop the claim that chiropractic adjustments impact the immune system and discuss the scientific merit of that claim. We provide a response to the ICA reports and explain why this claim lacks scientific credibility and is dangerous to the public. More than 150 researchers from 11 countries reviewed and endorsed our response. CONCLUSION: In their reports, the ICA provided no valid clinical scientific evidence that chiropractic care can impact the immune system. We call on regulatory authorities and professional leaders to take robust political and regulatory action against those claiming that chiropractic adjustments have a clinical impact on the immune system

Chiropractic students' perceptions of barriers and facilitators to joining a professional association

Background In Australia, about 1 in 3 chiropractors choose not to belong to either of the two professional associations and this is considerably lower compared to other health professional organisations in this country. The reasons for this remain unknown. We sought to explore possible reasons by asking chiropractic students their perceptions of barriers and facilitators to joining a professional association. However, we were unable to identify validated survey instruments that could be used to obtain information about reasons for joining health professional associations. Aim Therefore, the objectives of this study were to: 1) develop a survey instrument that captures information about what influences chiropractic students in joining professional association; and 2) identify factors that promote association membership among chiropractic students. Methods A literature review was undertaken to identify known determinants of professional association membership and were used to construct a preliminary survey instrument, which comprised 47 items. Six fourth-year chiropractic students assessed the preliminary survey instrument's content validity. Principal components analysis was used to establish the structure of the scales. Cronbach's alpha was derived to determine whether all items in each scale tapped a discrete construct. Logistic regression was used to examine the association between the scale scores and having joined a chiropractic professional association. Results In March 2019, 348 chiropractic students from Murdoch University (71.0%) responded to a voluntary, anonymous questionnaire. Principal components analysis resulted in the retention of 21 items that strongly loaded onto 6 factors. Internal consistency was found to be adequate. The results of the logistic regression analysis demonstrated that only "development of the profession" was significantly associated with have joined a professional chiropractic association (p = 0.049, OR = 2.22; 95% CI = 1.26-3.40). Conclusion Chiropractic organisations can probably most effectively increase membership numbers through raising awareness of their contribution to the development of the profession

Prevalence of low back pain in adolescents with idiopathic scoliosis: a systematic review

Background: Adolescent idiopathic scoliosis is the most common spinal deformity occurring in adolescents and its established prevalence varies from 2 to 3%. Adolescent idiopathic scoliosis has been identified as a potential risk factor for the development of low back pain in adolescents. The purpose of this study was to systematically review studies of the prevalence of low back pain in adolescents with idiopathic scoliosis in order to establish the quality of the evidence and determine whether the prevalence estimates could be statistically pooled. Methods: Systematic electronic searches were undertaken in PubMed, CINAHL, and CENTRAL without any restrictions. Studies were eligible for inclusion if they reported the prevalence of low back pain in adolescents with idiopathic scoliosis. Studies were excluded if they detailed the prevalence of pain in post-surgical subjects or were published in languages other than English or French. Data were reported qualitatively, since there was insufficient evidence for statistical pooling. Results: The electronic search strategies yielded 1811 unique studies. Only two studies fulfilled the eligibility criteria. The prevalence of low back pain in adolescents with idiopathic scoliosis ranged from 34.7 to 42.0%. However, these prevalence estimates should be viewed cautiously as the included studies were at high risk of bias. Conclusion: The results of this systematic review indicate that adolescents with idiopathic scoliosis frequently experience low back pain. However, there was insufficient evidence to confidently estimate low back pain prevalence in adolescents with idiopathic scoliosis and further studies are needed in this area

Validation of the scale on Satisfaction of Adolescents with Postoperative pain management-idiopathic Scoliosis (SAP-S)

Background: Spinal fusion is a common orthopedic surgery in children and adolescents and is associated with high pain levels postoperatively. If the pain is not well managed, negative outcomes may ensue. To our knowledge, there is no measure in English that assesses patient’s satisfaction with postoperative pain management following idiopathic scoliosis surgery. The aim of the present study was to assess the psychometric properties of the satisfaction subscale of the English version of the Satisfaction of Adolescents with Postoperative pain management – idiopathic Scoliosis (SAP-S) scale. Methods: Eighty-two participants aged 10–18 years, who had undergone spinal fusion surgery, fully completed the SAP-S scale at 10–14 days postdischarge. Construct validity was assessed through a principal component analysis using varimax rotation. Results: Principal component analysis indicated a three-factor structure of the 13-item satisfaction subscale of the SAP-S scale. Factors referred to satisfaction regarding current medication received (Factor 1), actions taken by nurses and doctors to manage pain (Factor 2) and information received after surgery (Factor 3). Cronbach’s alpha was 0.91, showing very good internal consistency. Data on satisfaction and clinical outcomes were also reported. Conclusion: The SAP-S is a valid and reliable measure of satisfaction with postoperative pain management that can be used in both research and clinical settings to improve pain management practices. Although it was developed and validated with adolescents who had undergone spinal fusion surgery, it can be used, with further validation, to assess adolescents’ satisfaction with pain management in other postoperative contexts
