Background: Cervical radiculopathy (CR) is a common cervical spine pathology. Following diagnosis, patients may seek conservative management including physical therapy (PT), chiropractic therapy (CT), and acupuncture therapy (AT). Literature supporting alternative management strategies remains limited and mixed, however, their utilization continues to rise. Methods: Patients with a first-time diagnosis of CR were identified from the M165Ortho PearlDiver database. Exclusion criteria included: <18 years of age, concurrent cervical myelopathy, therapy use prior to diagnosis, those with trauma, neoplasm or infection, and <90-days follow-up. Utilization rates and mean PT, CT, and AT sessions within 90-days of CR diagnosis were compared. Clinical and nonclinical predictors of alternative therapy utilization patterns were compared by multivariable logistic regression. Results: Of 789,970 identified CR patients, PT was noted for 132,929 (16.8%), CT for 34,354 (4.4%), and AT for 1,916 (0.2%) within 90-days. CT demonstrated the highest number of sessions (7.81 ± 6.37), followed by PT (7.36 ± 5.54), and AT (5.89 ± 4.97) (p < .05). Predictors of CT utilization, relative to PT were lower age (odds ratio [OR]: 0.84), lower comorbidity burden based on Elixhauser Comorbidity Index (OR: 0.91), region (South OR: 2.05, Northeast OR: 1.93, Midwest OR: 1.92), and insurance (Medicaid OR: 0.30 and Medicare OR: 0.92) (p < .001 for all). Predictors of AT utilization, relative to PT were lower age (OR: 0.93, p < .001), male sex (OR: 1.14, p = .004), region (West OR: 3.31, p < .001, Northeast OR: 2.76, p < .001, Midwest OR: 1.27, p = .002), and insurance (Medicaid OR: 0.29 and Medicare OR: 0.59, p < .001). Conclusions: Within 90-days following newly diagnosed CR, only a minority of patients utilized any form of therapy, despite typically being thought of as a first-line conservative management strategy. Among CR patients who did pursue therapy, PT was more commonly utilized than both CT and AT. The significance of nonclinical drivers of alternative therapeutic strategies suggests a lack of therapeutic consensus at a national level, potential inequities to access, and room for algorithm-driven care pathways.

Abstract Objectives The aim of this cross-sectional study was to update the results of the first Swiss Job Analysis Survey in 2009 with regard to the demographics of the chiropractors and their patients, practice characteristics, interprofessional collaboration, the importance of imaging, and job satisfaction. Methods In April 2020, the adapted 2009 questionnaire was electronically sent to all members of the Swiss Chiropractic Association ChiroSuisse (N = 316). Only complete questionnaires were included in the descriptive analysis. Demographic data were compared to all ChiroSuisse members. Results The response rate was 76.3%. The mean age of the participants was 49.9 ± 12.3 years and 62.2% were male. Among the younger chiropractors (≤ 15 years of professional experience), 51.6% were male. Almost half of the participants worked in a joint office and one in five worked in a multidisciplinary setting. The typical chiropractic patient was middle-aged, female and suffered most frequently from acute lower back/pelvis pain and second most frequently from neck pain. Diversified osseous adjustment was the most commonly used technique, followed by advice on activities of daily living and trigger point therapy. Images (X-ray, CT, MRI) were ordered in less than 20% of the patients. 95% of the chiropractors were satisfied with their career choice. Conclusions No changes to 2009 were observed in terms of the typical patient or the applied techniques. However, the Swiss chiropractors were more experienced, to a larger proportion female, more often worked in multidisciplinary settings, and ordered fewer images. Job satisfaction among Swiss chiropractors was high.

Objectives: This study aimed to elucidate the mechanisms of chiropractic care using resting electroencephalography (EEG), somatosensory evoked potentials (SEPs), clinical health assessments (Fitbit), and Patient-reported Outcomes Measurement Information System (PROMIS-29). Methods: Seventy-six people with chronic low back pain (mean age ± SD: 45 ± 11 years, 33 female) were randomised into control (<i>n</i> = 38) and chiropractic (<i>n</i> = 38) groups. EEG and SEPs were collected pre and post the first intervention and post 4 weeks of intervention. PROMIS-29 was measured pre and post 4 weeks. Fitbit data were recorded continuously. Results: Spectral analysis of resting EEG showed a significant increase in Theta, Alpha and Beta, and a significant decrease in Delta power in the chiropractic group post intervention. Source localisation revealed a significant increase in Alpha activity within the Default Mode Network (DMN) post intervention and post 4 weeks. A significant decrease in N30 SEP peak amplitude post intervention and post 4 weeks was found in the chiropractic group. Source localisation demonstrated significant changes in Alpha and Beta power within the DMN post-intervention and post 4 weeks. Significant improvements in light sleep stage were observed in the chiropractic group along with enhanced overall quality of life post 4 weeks, including significant reductions in anxiety, depression, fatigue, and pain. Conclusions: These findings indicate that many health benefits of chiropractic care are due to altered brain activity.

Abstract Background Spinal manipulation has been shown to affect muscle activity, posture, and pain. To date, no studies have examined the effect of manipulation on biomechanical factors during sitting. Therefore, the purpose of this study was to investigate the immediate effect of lumbar spinal manipulation on trunk muscle activation, spine posture and movements, and perceived ratings of transient pain in asymptomatic adults during prolonged office sitting. Methods Twenty healthy adults were recruited for a single laboratory session that included a standardized office sitting/data entry protocol (120 min total, 3 blocks of 40 min). Data were collected between July and August 2012. The first block (baseline) was immediately followed by two experimental blocks. Prior to the start of each experimental block, participants were transferred to a therapy plinth and placed side lying (right side down), and a random presentation of either a control or high velocity low amplitude thrust directed at L4/L5 was delivered. Continuous measures of muscle activity, spine posture, and spine movements were recorded throughout the sitting trials. Perceived transient pain was measured by visual analogue scale at 10-min intervals (including immediately before and after the randomized maneuvers). Results There were no significant differences in spine or pelvic posture or perceived back pain following either the manipulation or control maneuvers. Significantly reduced muscle activity and increased shifts of the lumbar spine angle were identified in the block following manipulation compared to both baseline and post control blocks. Conclusions Spinal manipulation does not appear to have an immediate impact on spine or pelvic posture in healthy adults but does appear to reduce muscle activity and increase spine movement during sitting. Future work should replicate this study with a larger population in a field setting. It may be worthwhile to explore the implication of reduced muscle activation and increased spine movements during prolonged sitting for office workers that receive manipulations or mobilizations during their workday.

A growing number of studies have found associations between adverse childhood experiences (ACEs) and adult well-being, with disparities between subpopulations. Limited research exists about the association between ACEs and cognitive disability, and variations by race and ethnicity. This study reports a cross-sectional analysis of 2019 Behavioral Risk Factor Surveillance System (BRFSS) data (n = 93 692) conducted in 2021. Logistic regression models examined the association between ACEs and cognitive disability (as defined by serious difficulty concentrating, remembering or making decisions because of a physical, mental, or emotional condition) and whether the association varied by race and ethnicity, adjusting for demographics, (age, gender, marital status), socioeconomic factors (income and education), and perceived general health. Exposures to 1, 2, 3, and 4 or more ACEs were associated with elevated odds of cognitive disability; the association varied by race and ethnicity (p for interaction less than 0.05). In stratified analyses, ACEs were positively associated with cognitive disability among the American Indian/Alaskan Native group, though significant only among those reporting 4 ACEs or more (OR: 2.89; 95% CI 1.25, 6.66). A dose response was observed for Black, White and Hispanic groups though the association was larger among Hispanic respondents. The elevated odds of cognitive disability associated with ACEs warrant additional research to understand mechanisms underlying this relationship across racial and ethnic groups. Additionally, interventions to prevent cognitive disability may benefit from considering ACEs across all populations, particularly among those with highest prevalence.

Objectives To highlight the detail obtained on a Cone Beam Computed Tomography (CBCT) scan of the craniocervical junction and its usefulness to Chiropractors who specialize in the upper cervical spine. A review of the dose considerations to patients vs radiography in a chiropractic clinical setting and to review the effective radiation dose to the patient. Methods A review of studies discussing cervical biomechanics, neurovascular structures, and abnormal radiographic findings, was discussed in relation to chiropractic clinical relevance. Further studies were evaluated demonstrating radiation dose to the patient from radiographs compared to CBCT. Results Incidental and abnormal findings of the craniocervical junction were shown to have superior visualization with CBCT compared to radiography. The radiation dose to the patient for similar imaging protocols to the craniocervical junction and cervical spine was equal or less utilizing CBCT when compared to radiographs. Conclusions The use of CBCT for visualization of the craniocervical junction and cervical spine in the chiropractic clinical setting allows for adjunctive visualization of the osseous structures which is germane to clinical protocol. Further with CBCT the effective dose to the patient is equal or less than similar imaging protocols utilizing radiographs to evaluate the craniocervical junction.

Abstract Background The Commission of the European Communities (CEC) has published: European Guidelines on Quality Criteria for Diagnostic Radiographic Images. These guidelines are considered a gold standard, recommended for use in quality assurance protocols. The objectives of this study: 1) Propose a graded classification format for Danish chiropractic clinics according to the CEC-quality criteria for diagnostic radiographic images of the lumbar spine. 2) Propose a reporting principle for quality of radiographic images. 3) Document variation in radiation exposure among clinics. Methods This is a cross-sectional study of image quality based on random sampling from 148 chiropractic clinics. Clinics were included if using: 1) Digital radiography and 2) The chiropractic picture and archiving system (KirPACS) at the Nordic Institute of Chiropractic and Clinical Biomechanics (NIKKB) in Denmark. A sample of 296 lumbar spine series were randomly collected from KirPACS (January 2018). Two independent observers reviewed 50 lumbar spine series twice with a 4-week interval, testing intra- and inter-observer reproducibility. The same observers then reviewed the remaining 246 radiographic studies. All studies were evaluated using the CEC Quality Criteria. Patient radiation dose values were retrieved from KirPACS (First quarter of 2020). Results A reporting and classification principle of diagnostic image quality was used in 148 chiropractic clinics. Compliance with the 22 CEC Quality Criteria had proportions ranging from 0.72–0.96 for 18 criteria, while 4 criteria specifying detail and definition ranged between 0.20–0.66. The proposed rating system (A to E) revealed: 18 A clinics, 28 B clinics, 32 C clinics, 25 D clinics and 45 E clinics (A = highest quality; E = lowest quality). The patient radiation reference dose in Denmark is 7 mGy for the AP/PA lumbar spine. Very few clinics exceed the reference dose value, approximately 50% of clinics were below 5 mGy. Conclusion A reporting principle is proposed for a graded classification format based on the CEC-quality criteria for diagnostic radiographic images of the lumbar spine. The Quality Criteria are for the most part met satisfactorily in 148 Danish chiropractic clinics, but important image details are compromised, in most cases, because of low patient radiation doses. The results of a patient radiation dose survey enabled documentation of variation in radiation exposure among chiropractic clinics.

Background: Physiological responses related to manual therapy (MT) treatment have been investigated over decades using various animal models. However, these studies have not been compiled and their collective findings appraised. The purpose of this scoping review was to assess current scientific knowledge on the physiological responses related to MT and/or simulated MT procedures in animal models so as to act as a resource to better inform future mechanistic and clinical research incorporating these therapeutic interventions.Methods: PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane, Embase, and Index of Chiropractic Literature (ICL) were searched from database inception to August 2019. Eligible studies were: (a) published in English; (b) non-cadaveric animal-based; (c) original data studies; (d) included a form of MT or simulated MT as treatment; (e) included quantification of at least one delivery parameter of MT treatment; (f) quantification of at least one physiological measure that could potentially contribute to therapeutic mechanisms of action of the MT. MT studies were categorized according to three main intervention types: (1) mobilization; (2) manipulation; and (3) massage. Two-phase screening procedures were conducted by a pair of independent reviewers, data were extracted from eligible studies and qualitatively reported.Results: The literature search resulted in 231 articles of which 78 met inclusion criteria and were sorted by intervention type. Joint mobilization induced changes in nociceptive response and inflammatory profile, gene expression, receptor activation, neurotransmitter release and enzymatic activity. Spinal manipulation produced changes in muscle spindle response, nocifensive reflex response and neuronal activity, electromyography, and immunologic response. Physiological changes associated with massage therapy included autonomic, circulatory, lymphatic and immunologic functions, visceral response, gene expression, neuroanatomy, function and pathology, and cellular response to in vitro simulated massage.Conclusion: Pre-clinical research supports an association between MT physiological response and multiple potential short-term MT therapeutic mechanisms. Optimization of MT delivery and/or treatment efficacy will require additional preclinical investigation in which MT delivery parameters are controlled and reported using pathological and/or chronic pain models that mimic neuromusculoskeletal conditions for which MT has demonstrated clinical benefit.

Abstract Background Fenestration of vertebra-basilar artery is an uncommon congenital vascular anomaly, which is identified by incidental findings on imaging in patients presented without related symptoms or in patients with intracerebral hemorrhage secondary to concomitant artery aneurysm or arteriovenous malformations. Yet, cases of fenestration being misdiagnosed as cerebral artery dissection have never been reported. Case presentation We present a patient of 66-year-old female with acute onset of dizziness after chiropractic manipulation of the neck. Neck computed tomography angiography (CTA) showed ‘double lumen’ sign and ‘intimal flap’ of the V1 segment of the vertebral artery, which led to the initial diagnosis of vertebral artery dissection (VAD). However, vertebral artery fenestration at V1 segment was eventually identified by multi-directional digital subtraction angiography (DSA). Interestingly, concomitant vertebral fenestration at V3 segment, basilar fenestration and basilar artery tip aneurysm was also revealed by DSA. Conclusion The triple fenestration at vertebrobasilar artery with basilar tip artery aneurysm is extremely rare, and the fenestration at the V1 segment of vertebral artery was easily misdiagnosed as VAD due to the similar imaging morphology.

This is a case report of an unusual cause of bilateral diaphragmatic palsy. A 54-year-old gentleman, presented to us with exertional dyspnea and chest heaviness for the past 6 months which had increased in the last 6 days. Dyspnea increased on lying down. He was diagnosed as pneumonia on the basis of X-ray and chest CT scan, received treatment for the same and responded to the therapy. However, breathlessness and hypercapnia persisted. He had unexplained hypercapnia for which extensive investigations were carried out. Neurological and cardiac assessments were essentially normal. On revisit clinical examination, he was found to have paradoxical diaphragmatic movement with respiration. Ultrasound of chest detected no diaphragmatic movement. Detailed history elicited that patient was fond of neck massage and neck cracking wherein his barber would bend his neck with jerk to either side after a haircut.After considering all possible etiologies; we concluded that it was a case of diaphragm palsy induced by barber neck manipulation, leading to Type-2 respiratory failure. The fact that the vital clues to the diagnosis were elicited by detailed history and thorough examination reinforces that history and clinical examination for doctors shall remain a very important tool for clinical diagnosis.

Objectives There is no current detailed profile of people seeking chiropractic care in Canada. We describe the profiles of chiropractors’ practice and the reasons, nature of the care provided to their patients and extent of interprofessional collaborations in Ontario, Canada.Design Cross-sectional observational study.Setting Primary care setting in Ontario, Canada.Participants We randomly recruited chiropractors from a list of registered chiropractors (n=3978) in active practice in 2015. Of the 135 randomly selected chiropractors, 120 were eligible, 43 participated and 42 completed the study.Outcome measures Each chiropractor recorded information for up to 100 consecutive patient encounters, documenting patient health profiles, reasons for encounter, diagnoses and care provided. Descriptive statistics summarised chiropractor, patient and encounter characteristics, with analyses accounting for clustering and design effects.Results Chiropractors provided data on 3523 chiropractor-patient encounters. More than 65% of participating chiropractors were male, mean age 44 years and had practised on average 15 years. The typical patient was female (59% of encounters), between 45 and 64 years (43%) and retired (21%) or employed in business and administration (13%). Most (39.4%) referrals were from other patients, with 6.8% from physicians. Approximately 68% of patients paid out of pocket or claimed extended health insurance for care. Most common diagnoses were back (49%, 95% CI 44 to 56) and neck (15%, 95% CI 13 to 18) problems, with few encounters related to maintenance/preventive care (0.86%, 95% CI 0.2 to 3.9) and non-musculoskeletal problems (1.3%, 95% CI 0.7 to 2.3). The most common treatments included spinal manipulation (72%), soft tissue therapy (70%) and mobilisation (35%).Conclusions This is the most comprehensive profile to date of chiropractic practice in Canada. People who present to Ontario chiropractors are mostly adults with a musculoskeletal condition. Our results can be used by stakeholders to make informed decisions about workforce development, education and healthcare policy related to chiropractic care.

Background: Surface imaging is a promising, noninvasive approach to assess regional perfusion in craniovascular disorders such as migraine. Methods: We used optical imaging to examine differences in facial blood volume at baseline and in response to ammonia inhalation (a noxious stimulus), as well as standardized measures of cardiovascular autonomic function, in healthy, non-headache controls ( n = 43) and in interictal migraine subjects ( n = 22). Results: Resting facial cutaneous oscillation (FCO) frequency was significantly different in migraine compared to healthy controls. Following ammonia inhalation, healthy controls showed a significant increase in resting FCO frequency, whereas this response was not significant in the migraine group. Standardized autonomic reflex parameters did not differ significantly between study groups, and facial cutaneous activity did not correlate with standardized cardiovascular autonomic reflex parameters, suggesting potentially different regulation. Conclusions: This approach to the assessment of craniofacial hemodynamic function appears to exhibit differing mechanisms from previously available techniques, and represents a promising new physiological biomarker for the study of craniofacial vascular function in migraine and potentially other craniovascular disorders.

Leonard F Vernon Sherman College of Chiropractic, Spartanburg, SC, USA Abstract: The standard definition of spontaneous regression (SR) of cancer is as follows, &ldquo;&hellip;when a malignant tumor partially or completely disappears without treatment or in the presence of therapy which is considered inadequate to exert a significant influence on neoplastic disease.&rdquo; SR is also known as Saint Peregrine tumor, the name taken from a young priest, Peregrine Laziosi (1260 [5]&ndash;1345, exact date is unknown), who had been diagnosed with a tumor of the tibia. The mass eventually grew so large that it broke through the skin and became severely infected. The available treatment for this condition was limited to amputation. Historical records report that on the day of surgery, physicians found that the tumor had disappeared and reportedly never returned. To date, the medical literature consists only of individual case studies and overviews of this phenomenon. The most cited work on the subject was done by surgeons Tilden Everson and Warren Cole who reviewed 176 published cases of SR from 1900 to 1960. While a percentage of these were found not to be cases of SR, there remained a number of unexplained cases. A frequent theme in many cases of SR is the co-occurrence of infection. Given the current interest in immunotherapy in the treatment of cancer, this article discusses one of the very early pioneers of this theory, William Bradley Coley, MD, a surgeon who was clearly ahead of his time. Ostracized by colleagues for his belief that stimulation of the immune system could in fact produce a regression of cancer, Coley remained convinced that his theory was right and, while he was not familiar with cytokines such as tumor necrosis factor (TNF), interferons, and streptokinase, he knew instinctively that an innate immune response was taking place.
