ABSTRACT Background The chronic low back pain (cLBP) literature rarely includes comprehensive characterization of demographic and biomedical factors in a large sample of individuals. The University of Pittsburgh Mechanistic Research Center, entitled, “Low Back Pain: Biological, Biomechanical, Behavioral Phenotypes (LB3P),” is part of the National Institutes of Health's Helping to End Addiction Long‐term Initiative. The LB3P conducted a prospective, observational cohort study to identify phenotypes of people with cLBP. Here, we report demographic and biomedical characteristics of a large cohort of individuals with cLBP, stratified by sex and age, collected at the in‐person enrollment visit. Methods The key eligibility criteria were adults with cLBP, English speakers, and identified in the electronic health record of our medical center. Recruitment strategies were through clinical partners who invited their patients to join the study and research registries. Participants completed demographic and biomedical surveys. Descriptive statistics were computed for the sample overall, and for the subgroups (male/female and age < 60/≥ 60). Results N = 1007 individuals (60% female) were enrolled, with an average age of 59 ± 17 years. Most participants were non‐Hispanic (90%), White (75%), and 53% attained college or higher education. 54% were married or had a partner, 43% were employed, 38% retired, 41% had an annual household income < $50 000, 20% had been off work for more than 30 days due to low back pain (LBP), 16% had applied for or received disability, and 6% were on worker's compensation. The majority were obese (average BMI of 31.5 kg/m2), 61% had back pain for > 5 years, and pain had been ongoing every or nearly every day in 76% of the sample. The participants reported a high prevalence of osteoarthritis (58%), anxiety (40%), depression (40%), vision impairment (35%), and balance problems/falls (31%). Among the chronic overlapping pain conditions, the most common were migraine or headache (29%), irritable bowel syndrome (16%), and temporomandibular joint dysfunction (12%). Previous low back surgery was reported by 25%. The most frequently reported LBP treatments during the previous month were exercise routine done on their own (58%), physical therapy, occupational therapy, or chiropractic care (33%), mindfulness, meditation, or relaxation (22%), and diet or nutrition counseling (21%). Medication intake during the last month was 43% for nonsteroidal anti‐inflammatory drugs, 18% for gabapentin, 13% for opioid, and 10% for antidepressants. Conclusions Describing comprehensive demographic and biomedical characteristics of individuals with cLBP stratified by sex and age will serve as a reference for clinicians and research planning, particularly with respect to comorbid conditions and utilization of treatment for cLBP. These data will be useful in future efforts to comprehensively phenotype cLBP.

Abstract Background Arthritis covers a range of chronic diseases presenting as joint pain and inflammation with prevalence of 20% in Canadians. Treatment guidelines for arthritis depend upon the type of arthritis but most include recommendations for rehabilitation interventions designed to optimize functioning and reduce disability. We set out to estimate the prevalence of healthcare utilization with different providers and to explore factors associated with utilization of different providers among Canadians with arthritis. Methods This population-based study used Canadian Community Health Survey data (2001–2018) restricted to respondents with arthritis (≥12 years). We used self-reported consultation with healthcare providers (medical doctor, chiropractor, physiotherapist, nurse, psychologist) (2001–2010), and self-reported regular healthcare provider (2015–2018). We calculated the 12-month prevalence of utilization with providers, and used modified Poisson regression to assess predisposing (e.g. age, sex, education), enabling (e.g. income, province) and need (e.g. self-percieved health) factors associated with utilization of providers. Results From 2001–2010 and 2015–2018, respectively, prevalence of utilization of medical doctors was 92.0% (95%CI: 91.7–92.2%) and 91.0% (95%CI: 90.5–91.5%); chiropractors 13.1% (12.8–13.4%) and 9.6% (9.1–10.1%); physiotherapists 14.5% (14.1–14.8%) and 9.4% (8.9–9.9%); nurses 14.2% (13.9–14.5%) and 7.5% (7.2–7.9%); psychologists 3.0% (2.8–3.1%) and 3.9% (3.5–4.2%). Females were more likely to see any provider. Users of chiropractic care were less likely to be smokers and more physically active with greater utilization in the western provinces than in the east. Those with poorer self-perceived health were more likely to see physiotherapists, nurses and psychologists. Consultation with a nurse (2001–2010) was more likely in the northern territories, while regular care from a nurse (2015–2018) was more likely in older age groups. Conclusions Canadians with arthritis were most likely to see medical doctors. Characteristics of healthcare utilizers varied by provider type. Geographical variation in utilization of chiropractors and physiotherapists likely related to differences by province and over time in what provincial health insurance covered while geographical variation in utilization of nurses was likely related to the lack of availability of medical doctors. Findings inform the need to strengthen healthcare delivery for Canadians, perhaps providing better access to providers of rehabilitation interventions.

Abstract Although reduced experimental pain habituation is proposed as a proxy of diminished endogenous pain modulatory capacity in chronic pain, prior studies show contradictory findings. Even across healthy participants, pain habituation varies substantially, which may relate to another measure of endogenous pain modulation, i.e., conditioned pain modulation (CPM). Hence, this study investigated the relationship between pain habituation and CPM. Pain habituation was assessed in 45 healthy participants between two blocks of 15–20 contact-heat stimuli applied to the hand. Habituation of subjective pain ratings and objective neurophysiological readouts (contact-heat evoked potential (CHEP) and palmar sympathetic skin response (SSR)) was investigated. CPM was assessed by comparing heat pain thresholds before and after hand immersion in a noxious cold (9 °C) and lukewarm water bath (32 °C, to control for repeated measures effects). Pain habituation showed a large variability, with subjective but not objective pain habituation correlating with cold-induced CPM effects (r = 0.50; p = 0.025). This correlation was not observed for ‘true’ CPM effects (corrected for repeated measures effects) nor for CPM effects induced by a lukewarm water bath. These findings suggest that the observed variability in subjective pain habituation may be influenced by both descending endogenous pain modulation and peripheral adaptation processes associated with repeated measures. Objective pain habituation readouts, i.e., CHEPs and SSRs, capture different, complementary aspects of endogenous pain modulation.

Older age, male sex, non-Hispanic Black/African American race/ethnicity, and daily opioid use were associated with decreased odds of IHM engagement. Older age, male sex, and increased depressive symptoms were associated with decreases in the count of IHM modalities used to manage pain. Metropolitan residency, higher family income, and higher education levels were associated with increased odds of exclusive nonpharmacologic modality engagement. Older age and increasing frequency of pain limiting life/work activities were associated with decreased odds of exclusive nonpharmacologic modality engagement.Conclusions: We identified several contrasts between factors prevalent among individuals with chronic pain and factors associated with engagement in nonpharmacologic and IHM modalities. These results support efforts to address barriers to accessing these modalities among subpopulations of adults with chronic pain (eg, older adults, individuals identifying as Black/African American, rural residents, and those with lower levels of education and income).Plain Language Summary: This study examined factors influencing the use of integrative health and non-drug treatments for chronic pain in the United States. Results revealed that metropolitan residence, higher income, and education were associated with increased use of these treatments, while older age, male sex, daily opioid use, and non-Hispanic Black/African American ethnicity were associated with decreased use. The findings emphasize the importance of addressing barriers to these forms of care, especially among older adults, Black/African American individuals, and those with higher depressive symptoms and lower education and income levels, who are more likely to have chronic pain.Keywords: integrative medicine, chronic pain, nonpharmacologic, opioids

Abstract Background Chiropractors commonly encounter patients who present for spine pain with parallel substance use. There is currently no widespread training within the chiropractic profession to prepare chiropractors to recognize and address substance use in clinical practice. The purpose of this study was to examine chiropractors’ confidence, self-perceptions, and interest in education associated with identifying and addressing patient substance use. Methods A 10-item survey was developed by the authors. The survey addressed chiropractors’ assessment of their training, experiences, and educational interest/needs regarding identifying and addressing patient substance use. The survey instrument was uploaded to Qualtrics and was electronically distributed to chiropractic clinicians at active and accredited English-speaking Doctor of Chiropractic degree programs (DCPs) in the United States. Results A total of 175 individual survey responses were returned from a total of 276 eligible participants (63.4% response rate) from 16 out of 18 active and accredited English-speaking DCPs (88.8% of DCPs) in the United States. Nearly half of respondents strongly disagreed or disagreed (n = 77, 44.0%) that they were confident in their ability to identify patients who misuse prescription medication. The majority of respondents (n = 122, 69.7%) indicated that they did not have an established referral relationship with local clinical providers who provide treatment for individuals who use drugs or misuse alcohol or prescription medications. Most respondents strongly agreed or agreed (n = 157, 89.7%) that they would benefit from participating in a continuing education course on topics related to patients who use drugs or misuse alcohol or prescription medications. Conclusions Chiropractors indicated a need for training to help them identify and address patient substance use. There is a demand among chiropractors to develop clinical care pathways for chiropractic referrals and collaboration with health care professionals who provide treatment for individuals who use drugs or misuse alcohol or prescription medications.

Abstract Background While pain is often the focus of clinical interventions, other clinical outcomes (e.g., discomfort, stiffness) might also contribute to patients’ functionality and well-being. Although researchers and clinicians may view discomfort, pain and stiffness as different constructs, it remains unclear how patients perceive and differentiate between these constructs. Therefore, the purpose of this study was to explore patients’ perceptions of pain, discomfort, and stiffness. Methods Chiropractic patients were invited to complete an online cross-sectional survey and describe what ‘discomfort’, ‘pain’ and ‘stiffness’ meant to them using their own words. Lexical and inductive qualitative content analyses were conducted independently and then triangulated. Results Fifty-three chiropractic patients (47.2% female, mean age: 39.1 ± 15.1 years) responded. The most common combinations of words to describe discomfort were “can be ignored” and “less severe than”. “Cannot be ignored” and “sharp shooting” were used to describe pain. “Limited range of motion” was used to describe stiffness. Qualitatively, five themes were developed: impact, character, feeling, intensity and temporality. Stiffness was described as limited movement/mobility. Although discomfort and stiffness impacted patients’ activities, patients remained functional; pain was described as stopping/limiting activities. Discomfort was described as dull and tingling, pain as sharp and shooting, and stiffness as tight and restricted. Patients felt displeased and annoyed when experiencing discomfort and stiffness but hurt and in danger of harm when experiencing pain. Discomfort and stiffness were described as less intense than pain, with shorter/intermittent duration; however, all constructs could be experienced constantly. Conclusion Patients perceived discomfort, pain and stiffness as different, yet overlapping constructs. This preliminary work advances our knowledge of how patients conceptualize these constructs, contributing to better understanding of what patients mean when reporting these experiences, potentially improving the clinician-patient communication.

Abstract Background As is the case around the globe, the Danish chiropractic community appears to be an active service provider for the athletic sub-population. However, a paucity of evidence elucidating the experiences, perceptions, and practices of individuals who identify as ‘sports chiropractors’ complicates strategic development efforts. Methods A sequential mixed-methods study was conceptualized in which interview responses from seven purposefully selected stakeholders provided context and informed a national descriptive survey exploring practice characteristics and opinions regarding sports chiropractic among Danish chiropractors. Results Thematic highlights included divided opinions on the criteria that define a sports chiropractor, the role of a chiropractor functioning beyond the clinic setting, and the need for a structured approach to developing sports chiropractic as a legitimate sub-specialty. The survey response rate was 34.9% (227 of 651), with 27% of responders identifying as a ‘sports chiropractor’. Compared to non-sports chiropractors, sports chiropractors engaged in a significantly higher level of interprofessional practice (3.8 versus 2.7 partners), in particular medical doctors (p = 0.016) and personal trainers (p <  0.001). Whether participants identified as a sports chiropractor or not, there was consensus that a high-quality post-graduate qualification and continued education was important. Generally speaking, the framing of sports chiropractic into a protected title was not a priority. Conclusion The Danish sports chiropractor tends to be male, has a specialist education and engages other chiropractors, medical practitioners and professional trainers more often as practice partners than generalist chiropractors. The position of the sports chiropractor as a ‘knowledgeable expert’ was seen as more important than establishing a protected title. Experiential training appears to be an untapped resource for developing real-world competency and gaining greater professional exposure. Given the potential for development across Europe, more focus is required on a strategic plan for embedding chiropractic professionals in inter-professional athletic health and performance practice settings.

Abstract Background Spine related disorders entail biological (somatic), psychological, and social factors. Though biological factors are often emphasized, psychosocial considerations may not be receiving proper attention in the chiropractic field. Chiropractors treat spine complaints and therefore should be trained in the full spectrum of the biopsychosocial model. This study examines the use of psychosocial related terminology in United States doctor of chiropractic program (DCP) curricula, the Council on Chiropractic Education (CCE) standards, and the National Board of Chiropractic Examiners (NBCE) test plans. Methods Nineteen academic course catalogs, CCE curricular standards and meta-competencies, and NBCE test plans were studied. Terms containing “psycho”, “soci”, “mental”, “econom”, “cultur”, “emotion”, “determinant”, “public”, “communit”, “neighbor”, “behav”, or “cognitive” were identified in each document. Frequency of use, context of use, thematic categorization, and percentage of use compared to overall content were calculated and described. Results ‘Public’ is the most commonly used psychosocial related term in DCP curricula. ‘Determinant’ was used in 1 DCP curriculum. The number of courses with psychosocial related terminology in course titles and course descriptions ranged from 1 to 5 and 3 to 12, respectively. Most terms are found in clinical skills, special populations, and other miscellaneous courses, with fewer terms found in psychology and public health courses. Terminology use in course titles and descriptions compared to overall content ranges from 3.40 to 14.86%. CCE uses terminology 17 times across 5 (out of 8) total meta-competencies. NBCE includes terminology in test plans I and II, but not III or IV. Conclusions Despite evidence suggesting the influential role of psychosocial factors in determinants of health and healthcare delivery, these factors are poorly reflected in United States DCP curricula. This underappreciation is further evidenced by the lack of representation of psychosocial terminology in NBCE parts III and IV test plans. The reasons for this are theoretical; lack of clarity or enforcement of CCE meta-competencies may contribute.

Abstract Background Most cases of low back pain (LBP) are regarded as non-specific and current studies indicate that for many this is a chronic recurrent condition, in which people experience episodes of pain with symptom-free periods in between. It is likely that acute exposure to some factors triggers the reappearance of new episodes in recurrent LBP regardless of the causality of the underlying condition (i.e. risk factors). Additionally, it has been shown that LBP patients present with different trajectories and different trajectories possibly have different triggers. Hence, dividing patients into some clinically meaningful subgroups may offer new insights into triggers, effective preventive strategies and, therefore, prognosis. This study aims to identify self-reported triggers and trajectories of episodes of recurrent LBP and to examine the prognostic association between different triggers and LBP trajectories. Methods This is a longitudinal, multicentre, Australia-wide observational study of patients with recurrent non-specific LBP. Two hundred adults with at least a one-year history of LBP will be recruited from primary care clinics or private practices and followed for a year. Each will receive an SMS every fortnight (26 time-points in total) enquiring the occurrence of a new episode of pain in the past 2 weeks and its intensity. Upon report of a new episode, a telephone interview will be performed to appraise exposure to self-nominated triggers in a period of 24 h preceding the pain. Trajectories will be identified by latent class analysis at the end of the follow-up based on the pain intensity, frequency, and length of episodes. Triggers will be categorised into physical and psychosocial groups. Generalised linear mixed models with logit links will be used to explore pain triggers associated with pain trajectories. Discussion The completion of this study will provide insight into the patients’ self-reported triggers of LBP and also their possible prognostic association with different trajectories. Some newly-identified and pre-identified triggers are likely to be found and reported.

Abstract Background Taping is a common treatment modality used by many rehabilitation providers. Several types of tapes and taping methods are used in the treatment of musculoskeletal dysfunction and pain. Purpose To summarize and map the evidence related to taping methods used for various joints and conditions of the musculoskeletal system, and to provide clinicians and researchers with a user-friendly reference with organized evidence tables. Data sources The PEDro, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register for Controlled Trials, PubMed, and PROSPERO databases were searched from inception through October 31, 2019. Study selection Eligible studies were selected by two independent reviewers and included either systematic reviews (SRs) or randomized controlled trials (RCTs) and included a musculoskeletal complaint using a clinical outcome measure. Data extraction Data was extracted by two investigators independently. Risk of bias and quality were assessed using A MeaSurement Tool to Assess systematic Reviews (AMSTAR) for SRs or the Physiotherapy Evidence Database (PEDro) scale for RCTs. The protocol was registered with PROSPERO (CRD42019122857). Data synthesis Twenty-five musculoskeletal conditions were summarized from forty-one SRs and 127 RCTs. There were 6 SRs and 49 RCTs for spinal conditions. Kinesio tape was the most common type of tape considered. Four evidence tables representing the synthesized SRs and RCTs were produced and organized by body region per condition. Limitations Inclusion of only English language studies. Also, the heterogeneous nature of the included studies prevented a meta-analysis. Conclusions There is mixed quality evidence of effectiveness for the different types of taping methods for different body regions and conditions. All of the SRs and RCTs found during our search of the taping literature have been organized into a series of appendices. A synthesis of the results have been placed in evidence tables that may serve as a useful guide to clinicians and researchers.

Abstract Background Profiles of health professions practice can inform pre-professional education, provide evidence to assist with interprofessional practice, and inform policy development. An understanding of the profile of patients seeking osteopathy care is emerging. Current research suggests that musculoskeletal presentations predominate with approximately one-third of patients presenting with co-morbid diseases. There is little data on these presentations in Australian osteopathy practice. This study aimed to describe the patient demographics, clinical presentations, health behaviours and determinants of health, including health literacy, of those attending for care at an Australian student-led osteopathy clinic. Methods A convenience sample design was utilised where consecutive patients presenting for their initial consultation were invited to complete a health information questionnaire during 2016–2017. The questionnaire explored a range of health behaviours and the patient’s health status. Data from the clinical records were also extracted to establish the presenting complaint, duration of the complaint and pertinent demographics. Descriptive statistics were generated for each variable. Results Data were available for 1617 patients presenting for their initial consultation. The mean age of patients was 33.7 (±13.1) years with 55% (n = 887) identifying as female. Acute presentations predominated (n = 840, 52%), with presentations affecting the spine being the most common (57.8%). Most patients rated their health status as good to very good (75%). Approximately 7.5% of patients were identified as having low health literacy and 55.9% were currently suffering from one or more co-morbid presentations. Conclusions The demographic profile and presenting complaints of patients presenting to a student-led osteopathy clinic are largely consistent with other Australian private practice profiles. The current work also identified co-morbid presentations, and positive and negative health behaviours. Osteopaths may play a role in the management of, or referral for, these presentations where health behaviours require change, or management of co-morbid conditions is beyond the scope of practice. The increasing volume of patient profile literature globally suggests that osteopaths can play a substantial role in the management of musculoskeletal complaints. Further, osteopathy may play a role in screening determinants of health, and engage in multidisciplinary care to ensure those patients with co-morbid conditions or adverse health behaviours are managed appropriately.

Abstract Introduction Low back pain (LBP) poses a significant burden of disease worldwide, and identifying safe and effective non-pharmacologic treatment options for LBP is a research priority. The aim of this study was to pilot a clinical trial of a portable pulsed electromagnetic field (PEMF) therapy device for subjects with mixed duration non-specific LBP. Methods This work was a randomized, double-blind, sham-controlled, parallel-group study conducted at a chiropractic school outpatient clinic. The primary end point was functional capacity measured by the Oswestry Disability Index (ODI) at baseline, 6 weeks, and 12 weeks. Analysis was conducted on the intent-to-treat population and as a trend of change in pain scores over time using the Freidman test of repeated measures. Results Forty-two participants were randomized to receive usual care plus PEMF therapy or usual care plus sham, and 25 completed the study. Significant improvements in ODI scores from baseline to week 6 were reported in the experimental group (χ 2 = 14.68, p < 0.001, compared with patients in the sham group, χ 2 = 4.00, p = 0.135, n.s.). This difference persisted at week-12 follow-up. Adverse events were rare and mild. Conclusion It is feasible to conduct a clinical trial of a PEMF therapy device for non-specific LBP. This work shows that the device was safe and provides preliminary evidence of effectiveness in improving function in patients with non-specific LBP.

Abstract Background While chiropractors are integrating into multidisciplinary settings with increasing frequency, the perceptions of medical providers and patients toward adding chiropractors to existing healthcare teams is not well-understood. This study explored the qualities preferred in a chiropractor by key stakeholders in a neurorehabilitation setting. Methods This qualitative analysis was part of a multi-phase, organizational case study designed to evaluate the planned integration of a chiropractor into a multidisciplinary rehabilitation team. The setting was a 62-bed rehabilitation specialty hospital located in the northeastern United States. Participants included patients, families, community members, and professional staff of the administrative, medical, nursing, and therapy departments. Data collection consisted of audiotaped, individual interviews and profession-specific focus groups guided by a semi-structured interview schedule. Transcripts were imported into a qualitative data analysis program for data analysis. An iterative coding process using thematic content analysis categorized key themes and domains. Results Sixty participants were interviewed in June 2015, including 48 staff members, 6 patients, 4 family members, and 2 community members. Our analysis generated a conceptual model of The Preferred Chiropractor for Multidisciplinary Rehabilitation Settings composed of 5 domains and 13 themes. The central domain, Patient-Centeredness, or the provision of healthcare that is respectful, responsive, and inclusive of the patient’s values, preferences, and needs, was mentioned in all interviews and linked to all other themes. The Professional Qualities domain highlighted clinical acumen, efficacious treatment, and being a safe practitioner. Interpersonal Qualities encouraged chiropractors to offer patients their comforting patience, familiar connections, and emotional intelligence. Interprofessional Qualities emphasized teamwork, resourcefulness, and openness to feedback as characteristics to enhance the chiropractor’s ability to work within an interdisciplinary setting. Organizational Qualities, including personality fit, institutional compliance, and mission alignment were important attributes for working in a specific healthcare organization. Conclusions Our findings provide an expanded view of the qualities that chiropractors might bring to multidisciplinary healthcare settings. Rather than labeling stakeholder perceptions as good, bad or indifferent as in previous studies, these results highlight specific attributes chiropractors might cultivate to enhance the patient outcomes and the experience of healthcare, influence clinical decision-making and interprofessional teamwork, and impact healthcare organizations.

Abstract Background Despite widespread use by manual therapists, there is little evidence regarding the reliability of thoracic spine static palpation to test for a manipulable lesion using stiffness or tenderness as diagnostic markers. We aimed to determine the interrater agreement of thoracic spine static palpation for segmental tenderness and stiffness and determine the effect of standardised training for examiners. The secondary aim was to explore expert consensus on the level of segmental tenderness required to locate a “manipulable lesion”. Methods Two experienced chiropractors used static palpation of thoracic vertebrae on two occasions (pragmatic and standardised approaches). Participants rated tenderness on an 11-point numerical pain rating scale (NPRS) and raters judged segmental stiffness based on their experience and perception of normal mobility with the requested outcomes of hypomobile or normal mobility. We calculated interrater agreement using percent agreement, Cohen’s Kappa coefficients (κ) and prevalence-adjusted bias-adjusted Kappa coefficients (PABAK). In a preliminary study, an expert panel of 10 chiropractors took part in a Delphi process to identify the level of meaningful segmental tenderness required to locate a “manipulable lesion”. Results Thirty-six participants (20 female) were enrolled for the reliability study on the 13th March 2017. Mean (SD) age was 22.4 (3.4) years with an equal distribution of asymptomatic (n = 17) and symptomatic (n = 17) participants. Overall, the interrater agreement for spinal segmental stiffness had Kappa values indicating less than chance agreement [κ range − 0.11, 0.53]. When adjusted for prevalence and bias, the PABAK ranged from slight to substantial agreement [0.12–0.76] with moderate or substantial agreement demonstrated at the majority of spinal levels (T1, T2 and T6 to T12). Generally, there was fair to substantial agreement for segmental tenderness [Kappa range 0.22–0.77]. Training did not significantly improve interrater agreement for stiffness or tenderness. The Delphi process indicated that an NPRS score of 2 out of 10 identified a potential “manipulable lesion”. Conclusion Static palpation was overall moderately reliable for the identification of segmental thoracic spine stiffness and tenderness, with tenderness demonstrating a higher reliability. Also, an increased agreement was found within the mid-thoracic spine. A brief training intervention failed to improve reliability.

Recent research has shown that chiropractic spinal manipulation can alter central sensorimotor integration and motor cortical drive to human voluntary muscles of the upper and lower limb. The aim of this paper was to explore whether spinal manipulation could also influence maximal bite force. Twenty-eight people were divided into two groups of 14, one that received chiropractic care and one that received sham chiropractic care. All subjects were naive to chiropractic. Maximum bite force was assessed pre- and post-intervention and at 1-week follow up. Bite force in the chiropractic group increased compared to the control group (p = 0.02) post-intervention and this between-group difference was also present at the 1-week follow-up (p &lt; 0.01). Bite force in the chiropractic group increased significantly by 11.0% (&plusmn;18.6%) post-intervention (p = 0.04) and remained increased by 13.0% (&plusmn;12.9%, p = 0.04) at the 1 week follow up. Bite force did not change significantly in the control group immediately after the intervention (&minus;2.3 &plusmn; 9.0%, p = 0.20), and decreased by 6.3% (&plusmn;3.4%, p = 0.01) at the 1-week follow-up. These results indicate that chiropractic spinal manipulation can increase maximal bite force.

Abstract Background Falls are a major health issue in the elderly people and an important cause of bone fracture. The aim of this study was to determine the association between quadriceps muscle strength (QMS) and falls in the elderly subjects. Methods All eligible participants of the Amirkola Cohort Study entered the study. Data regarding demographic characteristics, clinical and laboratory examinations were provided between 2011 to 2014. Occurrence of falls during previous year was determined by interview and review of the medical records. The study patients were divided into low, moderate and high muscle strength groups according to QMS values ≥ 30, 15–30, and < 15 kg respectively). Association between muscle strength and falls was determined by using multiple logistic regression analysis with calculation of odds ratio (OR). Results A total 1028 participants (females, 44.3%) were analyzed and 178(17.3%) subjects experienced a fall. Individuals with falls had higher age (p = 0.001) and lower QMS value (p = 0.001). After adjustment for all clinical and demographic variables, occurrence of falls was negatively associated with QMS and positively associated with age > 70 years old. Compared to group with QMS ≥ 30 kg, the prevalence of falls in low and moderate QMS groups increased by OR = 3(95% CI, 1.78–5.05) and 2.18 (95% CI, 1.22–3.42) respectively. Conclusion These findings indicate that older subjects with lower QMS are at greater risk of falls. These findings provide a rational for muscle strengthening exercise in older people.

Abstract Background Tobacco use remains a leading cause of death and disability in the United States. Health professionals need to address the use of tobacco products by their patients, but chiropractic clinical systems often remain unsupported and underappreciated in their role to facilitate tobacco use cessation. Methods This pilot study tested an intervention to assist a chiropractic community to implement sustainable health systems changes for tobacco use based on U.S. Public Health Service guidelines. Chiropractors were educated on the Ask, Advise, Refer (AAR) approach, provided with ongoing guidance, and followed for six months to assess systems change. The study was conducted from March 2016 to July 2017. Results Evidence of a systematic process in place to conduct AAR was present in all clinics by the end of the fourth month of the intervention period. Although no clinic had sustained health system change for full AAR, all six of the clinics made progress in the individual AAR components. Furthermore, five clinics achieved sustained system change for the Ask component, as after systems change was achieved, the rate of tobacco user identifications did not drop below 50%. For the Advise component, five clinics succeeded in having individual months of ≥50% of tobacco users being advised, and three clinics achieved the formal definition of systems change. For the Refer component, no clinic achieved system change, although four had individual months of ≥50% of tobacco users being referred. The patient quit rate was 13.3% (n = 15) for the 30-day follow-up and 16.7% (n = 6) for the three-month follow-up. Conclusions This study demonstrates the feasibility of implementing a health systems change in the chiropractic setting to identify tobacco users, to advise them to quit, and to refer users for cessation services.
