Frequency and indication of non-musculoskeletal examinations: a cross-sectional survey of Quebec chiropractors.

BACKGROUND: Approximately 1% of low back pain is estimated to be caused by serious systemic diseases, including cancer, infection, or abdominal aortic dissection. This study aimed to determine the frequency of execution of non-MSK physical examination procedures among Quebec chiropractors and to identify the clinical context that prompts them to use these physical examination procedures. METHODS: Cross-sectional survey containing 44 questions administered to a random sample of Quebec chiropractors using a succession of online, postal and phone questionnaires. The 4-part survey questionnaire contained six demographic questions, 28 single-choice questions to determine the frequency of execution of non-MSK physical examination procedures, seven short clinical vignettes for which the respondents had to select the non-MSK examinations that would be required, and two questions inquiring about the proportion of new patients for which participants' felt non-MSK examinations were necessary and whether appropriate assessments were performed. The questionnaire was pilot tested, and feedback received integrated prior to administration. We conducted descriptive statistics, Pearson correlations, and an ANOVA. RESULTS: The survey was completed by 182 chiropractors (response rate: 36.4%). The most commonly non-musculoskeletal examination performed daily were blood pressure (12.1%) and cranial nerves (4.9%). The most common tests never performed were oxygen saturation (68.7%), cardiac auscultation (69.2%), tibio-brachial index (71.4%), breast (86.8%), rectal (96.7%), testicular (95.6%), and vaginal (99.9%) exams. Female chiropractors and Quebec University in Trois-Rivières graduates reported that a significantly higher proportion of their new patients required a non-musculoskeletal physical examination compared to male participants (37.2% vs 28.3%) or Canadian Memorial Chiropractic College graduates (33.9% vs 19.9%). Reason for not performing a physical examination included the belief that another healthcare professional was better positioned to perform and/or interpret the related tests (76.4%). CONCLUSIONS: Vital signs and cranial nerve examinations were the most frequency performed non-musculoskeletal examinations reported by chiropractors. Apart from the genitourinary exam almost never performed, most participants chose non-musculoskeletal examinations deemed appropriate for the patient's presentation.

Nutrigenomics: SNPs correlated to physical activity, response to chiropractic treatment, mood and sleep.

Abstract: Nutrigenomics, a rapidly evolving field that bridges genetics and nutrition, explores the intricate interactions between an individual's genetic makeup and how they respond to nutrients. At its core, this discipline focuses on investigating Single Nucleotide Polymorphisms (SNPs), the most common genetic variations, which significantly influence a person's physiological status, mood regulation, and sleep patterns, thus playing a pivotal role in a wide range of health out-comes. Through decoding their functional implications, researchers are able to uncover genetic factors that impact physical fitness, pain perception, and susceptibility to mood disorders and sleep disruptions. The integration of nutrigenomics into healthcare holds the promise of transformative interventions that cater to individual well-being. Notable studies shed light on the connection between SNPs and personalized responses to exercise, as well as vulnerability to mood disorders and sleep disturbances. Understanding the intricate interplay between genetics and nutrition informs targeted dietary approaches, molding individual health trajectories. As research advances, the convergence of genetics and nourishment is on the brink of reshaping healthcare, ushering in an era of personalized health management that enhances overall life quality. Nutrigenomics charts a path toward tailored nutritional strategies, fundamentally reshaping our approach to health preservation and preventive measures.

Associations between demographics and clinical ideology, beliefs, and practice patterns: a secondary analysis of a survey of randomly sampled United States chiropractors.

BACKGROUND: The chiropractic profession in the United States (US) has a long history of intra-professional discourse surrounding ideology and beliefs. Large-scale efforts have evaluated 3 distinctive subgroups of US chiropractors focused on these areas of practice: spine/neuromusculoskeletal, primary care, and vertebral subluxation. To our knowledge, there have not been any prior studies exploring the factors associated with these ideology and belief characteristics of these subgroups. The purpose of this study was to explore, describe, and characterize the association of US chiropractors' ideology, beliefs, and practice patterns with: 1) chiropractic degree program of graduation, 2) years since completion of chiropractic degree, and 3) US geographic region of primary practice. METHODS: This was a secondary analysis of a cross-sectional survey of a random sample of US licensed chiropractors (n = 8975). A 10% random sample was extracted from each of the 50 states and District of Columbia chiropractic regulatory board lists. The survey was conducted between March 2018-January 2020. The survey instrument consisted of 7 items that were developed to elicit these differentiating ideologies, beliefs, and practice patterns: 1) clinical examination/assessment, 2) health conditions treated, 3) role of chiropractors in the healthcare system, 4) the impact of chiropractic adjustments [spinal manipulation] in treating patients with cancer, 5) vaccination attitudes, 6) detection of subluxation on x-ray, and 7) x-ray utilization rates. Multinomial regression was used to analyze associations between these 7 ideology and practice characteristic items from the survey (dependent variables) and the 3 demographic items listed above (independent variables). RESULTS: Data from 3538 respondents (74.6% male) were collected with an overall response rate of 39.4%. Patterns of responses to the 7 survey items for ideologies, beliefs, and practice characteristics were significantly different based on chiropractic degree program of graduation, years since completion of chiropractic degree, and geographic region of primary practice. CONCLUSIONS: Among US chiropractors, chiropractic program of graduation, years since completion of chiropractic degree, and geographic region of primary practice are associated with variations in clinical ideology, beliefs, and practice patterns. The wide variation and inconsistent beliefs of US chiropractors could result in public confusion and impede interprofessional integration.

The perceived barriers and facilitators for chiropractic care in older adults with low back pain; insights from a qualitative exploration in a dutch context.

BACKGROUND: Understanding care seeking behaviour is vital to enabling access to care. In the context of low back pain (LBP), chiropractors offer services to patients of all ages. Currently, geriatric sub-populations tend to be under-investigated, despite the disproportionate effects of LBP on older adults. In the Netherlands, the chiropractic profession is relatively unknown and therefore, generally speaking, is not considered as the first choice for conservative musculoskeletal primary health care. The aim of this paper was to explore the experiences of older adults with LBP, seeking chiropracic care for the first time, in order to identify perceived barriers and facilitators in this process. METHODS: Stage 1: Participants 56 years of age and older with chronic LBP who either sought or did not seek chiropractic care were interviewed to provide detailed information on the factors that promoted or impeded care-seeking behaviour. A purposive sampling strategy was used to recruit participants through a network of researchers, chiropractors and other healthcare professionals offering musculoskeletal health care services. Individuals with underlying pathology, previous surgery for LBP, or insufficient mastery of the Dutch language were excluded. Data were collected until saturation was reached and thematically analysed. Stage 2: To further explore the themes, a focus group interview was conducted with a provider stakeholder group consisting of:two physiotherapists, a nurse practitioner, a geriatrician, and a chiropractor. All interviews were conducted online, voice recorded, and transcribed verbatim. RESULTS: We interviewed 11 older adults with low back pain. During this process four themes emerged that captured their perception and experiences in either seeking or dismissing chiropractic care for their LBP; these being 'generic', 'financial', 'expectation', and 'the image of the chiropractor'. The focus group members largely confirmed the identified themes, highlighting a lack of awarenes and accessibility as key barriers to care. On the other hand, whe chiropractior as an alternative care provider, with a focus on manual interventions, was seen as a facilitator. CONCLUSIONS: The lack of knowledge about chiropractic care was found to be the most important barrier to seeking care. The most important facilitator was insufficient resolution of their symptoms following previous care, making patients look further for a solution for their problem. These barriers and facilitators seem not to differ greatly from barriers and facilitators found among younger patients with neck pain. Age and health condition may therefore be weak determinants of care. This new information may help us optimize accessibility for older adults to the chiropractor.

Demographics of and Costs to Users of Chiropractic Services in the United States with Neck or Back Pain not Meeting Guideline-Based Minimum Treatment Frequency Thresholds.

Context: Acceptance of chiropractic services as an effective therapy for neck or back pain has been well established with randomized controlled trials (RCTs); however, there have been limited observations made on the treatment frequency patterns seen in the real world. Objective: The purpose of this study is to identify chiropractic users with neck or back pain who did not meet recommended treatment frequency guidelines and examine their demographics and chiropractic costs. Design: In this cross-sectional retrospective study, the nationally representative 2017 Medical Expenditure Panel Survey database was used. Setting: This study used nationally representative US survey data. Participants: Inclusion criteria were adults aged 18 years and older with a diagnosis of neck or back pain with one or more chiropractic visits in 2017. Outcomes Measures: Chiropractic utilization was categorized as concordant or discordant with treatment frequency guidelines; concordant was defined as 5 or more visits to a chiropractor within any 2-month time frame or at least 12 total visits during the year. Discordant was defined as circumstances not meeting concordant criteria. The groups were compared by demographics including age, sex, race, region, years of education, health insurance coverage, employment status, family income, presence of headache diagnosis, Charlson Comorbidity Index score and the presence of any limitation of physical function. Comparisons were made between the two groups using Chi-squared tests. Logistic regression was used to adjust for covariates. Results: There were 159 and 310 adults classified as concordant and discordant, respectively (weighted total: 1 849 108 [31.44%] and 4 032 541 [68.56%], with significantly different mean chiropractic costs of $2555 and $434, respectively. Significant independent predictors of discordant chiropractic utilization were race, years of education, family income and the presence of any limitation of physical function. Conclusions: Most chiropractic users with diagnosed neck or back pain were considered discordant with treatment frequency guidelines, which may indicate inefficiencies in treatment and inefficient use of healthcare resources.

Association between chiropractic spinal manipulation and lumbar discectomy in adults with lumbar disc herniation and radiculopathy: retrospective cohort study using United States' data.

OBJECTIVES: Chiropractic spinal manipulative therapy (CSMT) and lumbar discectomy are both used for lumbar disc herniation (LDH) and lumbosacral radiculopathy (LSR); however, limited research has examined the relationship between these therapies. We hypothesised that adults receiving CSMT for newly diagnosed LDH or LSR would have reduced odds of lumbar discectomy over 1-year and 2-year follow-up compared with those receiving other care. DESIGN: Retrospective cohort study. SETTING: 101 million patient US health records network (TriNetX), queried on 24 October 2022, yielding data from 2012 query. PARTICIPANTS: Adults age 18-49 with newly diagnosed LDH/LSR (first date of diagnosis) were included. Exclusions were prior lumbar surgery, absolute indications for surgery, trauma, spondylolisthesis and scoliosis. Propensity score matching controlled for variables associated with the likelihood of discectomy (eg, demographics, medications). INTERVENTIONS: Patients were divided into cohorts according to receipt of CSMT. PRIMARY AND SECONDARY OUTCOME MEASURES: ORs for lumbar discectomy; calculated by dividing odds in the CSMT cohort by odds in the cohort receiving other care. RESULTS: After matching, there were 5785 patients per cohort (mean age 36.9±8.2). The ORs (95% CI) for discectomy were significantly reduced in the CSMT cohort compared with the cohort receiving other care over 1-year (0.69 (0.52 to 0.90), p=0.006) and 2-year follow-up (0.77 (0.60 to 0.99), p=0.040). E-value sensitivity analysis estimated the strength in terms of risk ratio an unmeasured confounding variable would need to account for study results, yielding point estimates for each follow-up (1 year: 2.26; 2 years: 1.92), which no variables in the literature reached. CONCLUSIONS: Our findings suggest receiving CSMT compared with other care for newly diagnosed LDH/LSR is associated with significantly reduced odds of discectomy over 2-year follow-up. Given socioeconomic variables were unavailable and an observational design precludes inferring causality, the efficacy of CSMT for LDH/LSR should be examined via randomised controlled trial to eliminate residual confounding.

Neck Pain and Headache After Pinealectomy: Improvement with Multimodal Chiropractic Therapies.

BACKGROUND Pineal gland tumors are rare central nervous system tumors, and while neck pain and headaches may be common among those who have had these tumors removed, there is little research regarding management of these symptoms. CASE REPORT A 45-year-old man with a history of pineal germinoma treated with pinealectomy, chemotherapy, radiation therapy, and ventriculoperitoneal shunt placement at age 21 presented with chronic neck pain and headaches, which initially improved following his surgery and concurrent therapies, yet progressively worsened over the following years. He required thyroid and testosterone medication because of radiation-induced hypopituitarism, yet was employed, and until recently, active with playing tennis. He had previously seen his primary care provider, orthopedist, and neurologist, and had been cleared of severe pathology via brain magnetic resonance imaging and was referred to the chiropractor. On examination, the patient had severely limited passive cervical spine range of motion, yet hat no neurologic deficits, and radiographs showed mild cervical spondylosis and cervicothoracic scoliosis. His history and presentation were suggestive of radiation-induced fibrosis. The patient's neck pain, headaches, and quality of life improved with multimodal treatments including spinal and soft-tissue manipulation, stretches, and yoga. CONCLUSIONS This case illustrates long-term sequelae of a pineal gland tumor and its treatment, including neck pain and headache, and improvement with multimodal chiropractic therapies. Despite the success in this case, these results are not broadly generalizable. Further research is needed to understand the natural history of symptoms and effectiveness of multimodal therapies among patients who have had pineal tumor surgery.

The association between chiropractic integration in an Ontario community health centre and continued prescription opioid use for chronic non-cancer spinal pain: a sequential explanatory mixed methods study.

BACKGROUND: Emerging evidence suggests that access to chiropractic care may reduce the likelihood of initiating an opioid prescription for spinal pain; however, the impact of chiropractic care for patients already prescribed opioids is uncertain. We undertook a sequential explanatory mixed methods study to evaluate the association between initiating chiropractic care and continued opioid use among adult patients attending an Ontario community health centre (CHC) and receiving opioid therapy for chronic non-cancer spinal pain. METHODS: We conducted a retrospective cohort study of 210 patient records between January 1, 2014 and December 31, 2020. We used generalized estimating equations, adjusted for patient demographics, co-morbidities, visit frequency, and calendar year, to evaluate the association between receipt versus non-receipt of chiropractic services and continued opioid use (e.g., unique opioid fills, number of refills, and dosages) up to one year following the index chiropractic visit. We also completed follow-up interviews with 14 patients and nine general practitioners from the CHC and integrated these data with our quantitative findings. RESULTS: Over 12-month follow-up, there were lower rates of opioid fills (incidence rate ratio [IRR] = 0.66; 95% confidence interval [CI], 0.52-0.83) and refills (IRR = 0.27; 95% CI, 0.17-0.42) among chiropractic recipients (n = 49) versus non-recipients (n = 161). Although patients who did and did not receive chiropractic care began the study with the same dose of opioids, recipients were less likely to be prescribed higher-dose opioids (i.e., ≥ 50 mg morphine equivalents daily) compared to non-recipients at three months (odds ratio [OR] = 0.14; 95% CI, 0.04-0.47), six months (OR = 0.14; 95% CI, 0.05-0.40), nine months (OR = 0.19; 95% CI, 0.07-0.57), and 12 months (OR = 0.22; 95% CI, 0.08-0.62). Interviews suggested that patient self-efficacy, limited effectiveness of opioids for chronic pain, stigma regarding use of opioids, and access to chiropractic treatment were important influencing factors. CONCLUSION: We found that continued prescription opioid use among patients with chronic non-cancer spinal pain who received chiropractic care was lower than in patients who did not receive chiropractic care. Four themes emerged in our qualitative interviews to help provide a richer understanding of this association. Randomized controlled trials are needed to establish the effect of chiropractic care on opioid use for chronic spinal pain.

Thoracic Schwannoma as an Unusual Cause of Sciatic Pain in the Chiropractic Office: A Case Report.

BACKGROUND Sciatica, which is pain radiating along the sciatic nerve distribution, is most often caused by degenerative conditions of the lower back and rarely results from lesions of the spinal cord. This case report illustrates a patient with suspected lumbar radiculopathy, ultimately diagnosed with a thoracic schwannoma after visiting a chiropractor. CASE REPORT A 61-year-old woman presented to a chiropractor with progressively worsening lower back pain radiating to the right lower extremity and unsteady gait. Her symptoms began 10 years previously and she had been diagnosed by an orthopedist with lumbar disc herniation causing radiculopathy via magnetic resonance imaging (MRI) and was treated with physical therapy and diclofenac. Upon examination by the chiropractor, the patient had bilateral lower-extremity neurologic deficits, hyperreflexia, and upgoing Babinski responses. The chiropractor ordered thoracic MRI, but the patient preferred to initiate a trial of care, which was unsuccessful. After a delay imposed by cardiac bypass surgery, the patient returned to the chiropractor with worsened symptoms and underwent thoracic MRI, revealing an intraspinal mass at T9. The patient underwent laminectomy and tumor removal, with histopathology confirming a diagnosis of schwannoma. The patient gradually improved after surgery with the help of rehabilitative exercises. CONCLUSIONS Clinicians should suspect a spinal cord lesion as a cause of sciatic pain when patients fail to improve with treatment, have a broad sensorimotor distribution unexplained by lumbar imaging findings, hyperreflexia/pathological reflexes, or other atypical findings (eg, negative neural tension tests). In such cases, MRI of the cervical and thoracic spine may be indicated.

A 68-Year-Old Woman with a Remote History of Breast Cancer Presenting with Low Back Pain to a Chiropractic Clinic in Hong Kong with Imaging Findings Consistent with a Vertebral Hemangioma and Vertebral Metastatic Lesions.

BACKGROUND Patients commonly visit chiropractic clinics for treatment for low back pain, which is often due to injury or degenerative spinal conditions. Rarely, serious underlying pathology may be identified. This report describes a 68-year-old woman with a remote history of breast cancer presenting with low back pain to a chiropractic clinic in Hong Kong with imaging findings consistent with vertebral hemangioma and vertebral metastatic lesions. CASE REPORT A 68-year-old woman with a history of breast cancer status after chemotherapy and mastectomy 20 years prior presented to a chiropractor with an acute exacerbation of chronic low back pain with lower extremity paresthesia. She previously visited her general practitioner and underwent radiography, which supported diagnoses of degenerative lumbar spondylosis and hemangioma of the fifth lumbar vertebra. Given the patient's worsening status and previous cancer, the chiropractor ordered lumbar magnetic resonance imaging at the initial visit, consistent with multilevel spinal metastasis. The chiropractor referred the patient to an oncologist who performed positron emission tomography/computed tomography, which suggested breast cancer recurrence and metastasis. The greatest hypermetabolic activity was evident within the level of the suspected vertebral hemangioma, suggesting this finding which initially appeared innocuous on plain radiography contained underlying metastasis. CONCLUSIONS This case illustrates that when patients fail to respond to treatment for low back pain, clinical referral should be undertaken for investigations to identify possible serious underlying pathology.

Association Between Chiropractic Utilization and Opioid Prescriptions Among People With Back or Neck Pain: Evaluation of the Medical Expenditure Panel Survey.

OBJECTIVE: The purpose of this study was to assess the association between patients in the United States seeing a chiropractor and receiving an opioid prescription for back or neck pain. METHODS: Medical Expenditure Panel Survey (Years 2012 to 2015) respondents for longitudinal panels 17 to 19 who participated in all 5 rounds were at least 18 years of age, did not have cancer, and reported back or neck pain. We defined chiropractic users as participants reporting at least 1 chiropractic visit for back or neck pain and opioid users as participants reporting purchase or receipt of a prescription classified as Multum Lexicon "60" and "191" for back or neck pain. We adjusted for socioeconomic and clinical variables using multiple logistic regression. RESULTS: The sample contained 4686 people, 21% of whom reported an opioid prescription for back or neck pain. Among opioid users, 14% reported a chiropractic visit for back or neck pain compared to 31% of nonopioid users. The adjusted odds ratio for chiropractic use among opioid users compared to nonopioid users was 0.46 (95% confidence interval, 0.36-0.57). CONCLUSION: Patients with back or neck pain who saw a chiropractor had approximately half the odds of reporting an opioid prescription compared to those who did not see a chiropractor.

Prevalence of Serious Pathology Among Adults with Low Back Pain Presenting for Chiropractic Care: A Retrospective Chart Review of Integrated Clinics in Hong Kong.

BACKGROUND There is a limited understanding of the frequency at which chiropractors encounter patients with serious pathology such as malignancy, fracture, and infection. This retrospective study aimed to estimate the prevalence and types of serious pathology among adults with new low back pain presenting to chiropractors in an integrated healthcare organization in Hong Kong, with the hypothesis that such pathology would be found in less than 5% of patients. MATERIAL AND METHODS We identified adults presenting to a chiropractor with new low back pain across 30 clinics with 38 chiropractors, and a subset with previously undiagnosed serious pathology from January 2020 through July 2022. Data were extracted from the electronic medical records, including messaging alerts for serious pathology, notes, radiology reports, and specialist follow-up. Descriptive statistics were utilized to analyze results. RESULTS Among the 7221 identified patients with new-onset low back pain (mean age 61.6±14.3), 35 presented with serious pathology. After excluding 54 cases not meeting inclusion criteria, the prevalence of serious pathology (95% CI) was 35/7221 (0.48%; 0.35-0.67%). Individual condition prevalence included metastasis (0.25%; 0.16-0.39%), fracture (0.12%; 0.07-0.24%), infection (0.04%; 0.01-0.12%), vascular pathology (0.03%; 0.01-0.10%), primary tumor (0.03%; 0.01-0.10%), and gastrointestinal emergency (0.01%; 0.00-0.08%). CONCLUSIONS This study found that serious pathology was uncommon among adults with new low back pain presenting for chiropractic care in Hong Kong, findings which are most consistent with previous research describing the prevalence of serious pathology among low back pain patients in primary care settings.

Metastatic Recurrent Breast Cancer Identified in the Chiropractic Office: Case Report and Literature Review.

BACKGROUND Breast cancer is the most common cancer in women and the most common cause of spinal metastasis, and it may recur months to years after treatment. CASE REPORT A 41-year-old woman, recovered from breast cancer, presented to a chiropractor with acute-on-chronic 3-week history of low back pain radiating to the right leg. She had seen 2 providers previously; lumbar spondylosis had been diagnosed via radiography. Given her recent symptom progression and cancer history, the chiropractor ordered lumbar magnetic resonance imaging, revealing L5 vertebral marrow replacement, suggestive of metastasis. The chiropractor referred her to an oncologist. While awaiting biopsy and oncologic treatments, the oncologist cleared the patient to receive gentle spinal traction and soft tissue manipulation, which alleviated her back pain. The patient continued radiation and chemotherapy, with low back pain remaining improved over 18 months. A literature review identified 7 previous cases of women presenting to a chiropractor with breast cancer metastasis. Including the current case, most had spinal pain and vertebral metastasis (75%) and history of breast cancer (88%) diagnosed a mean 5±3 years prior. CONCLUSIONS This case illustrates a woman with low back pain due to recurrent metastatic breast cancer, identified by a chiropractor, and the utility of a multidisciplinary approach to pain relief during oncologic care. Our literature review suggests that although uncommon, such patients can present to chiropractors with spinal pain from vertebral metastasis and have a known history of breast cancer. Conservative therapies should be used cautiously and under oncologic supervision in such cases.

Effectiveness of Multimodal Chiropractic Care Featuring Spinal Manipulation for Persistent Spinal Pain Syndrome Following Lumbar Spine Surgery: Retrospective Chart Review of 31 Adults in Hong Kong.

BACKGROUND The term "persistent spinal pain syndrome type 2" (PSPS-2) has been proposed by the International Association for the Study of Pain to replace the term "failed back surgery syndrome". This retrospective study aimed to evaluate effectiveness of multimodal care featuring chiropractic spinal manipulation (CSMT) in 31 adults in Hong Kong with PSPS-2. MATERIAL AND METHODS We identified new adult patients with PSPS-2 receiving CSMT from 2016 to 2018. Demographic and clinical data and baseline/follow-up numeric pain rating scale (NPRS) and Oswestry Disability Index (ODI) scores were extracted. Multiple linear regression was used to examine posttreatment NPRS and ODI reduction, with clinical variables as covariates. RESULTS Of 6589 patients with low back pain, 31 met criteria (mean age 52.2±13.7 years). Surgeries included laminectomy (81%), discectomy (13%), and fusion (6%). Mean baseline NRPS was 6.6±1.9; ODI was 43.8±15.1%. Patients received CSMT (100%), drop technique (81%), passive modalities (65%), soft tissue manipulation (13%), flexion-distraction (13%), and mechanical traction (13%). Mean posttreatment NPRS was 0.6±1.0; ODI was 2.4±3.3%. All patients had a minimum clinically important difference for NPRS (≥2/10) and ODI (≥30%). One year after treatment, 48% maintained improvement, 42% experienced recurrence; in 10%, follow-up was unavailable. Regression analysis identified younger age, shorter symptom duration, and greater baseline NPRS as predictors of NPRS reduction; and greater baseline ODI as a predictor of ODI reduction (all P<0.05). CONCLUSIONS Patients with PSPS-2 improved with multimodal care featuring CSMT, which was more effective in patients with younger age, shorter symptom duration, and higher baseline pain or disability levels.

[Chiropractic plus plum-blossom needling combined with flexibility training on attention deficit in mentally-retarded adolescents].

OBJECTIVE: To observe the clinical efficacy of chiropractic plus plum-blossom needling combined with flexibility training for attention deficit in mentally-retarded adolescents. METHODS: Thirty adolescents with mild mental retardation were randomly divided into a medical rehabilitation plus flexibility training group (10 cases, 2 cases dropped off), a flexibility training group (10 cases, 1 case dropped off) and a control group (10 cases). The patients in the flexibility training group received flexibility training, once every other day, 3 times a week for 12 weeks. The patients in the medical rehabilitation plus flexibility training group received chiropractic and plum-blossom needling at Baihui (GV 20) and Sishencong (EX-HN 1) on the basis of the treatment in the flexibility training group, once every other day, 3 times a week for 12 weeks. The patients in the control group did not receive any targeted physical training and medical rehabilitation. Tobii Pro Spectrum eye movement instrument was used to test the attention concentration (T), attention span (M), attention transfer (γ%) and attention distribution (η). RESULTS: Compared before treatment, T and M in the medical rehabilitation plus flexibility training group and the flexibility training group were increased after treatment (P<0.01, P<0.05), and γ% in the medical rehabilitation plus flexibility training group was increased after treatment (P<0.05). The increasing range of T, M and γ% in the medical rehabilitation plus flexibility training group and the flexibility training group was greater than that in the control group (P<0.01), and the increasing range of T and γ% in the medical rehabilitation plus flexibility training group was greater than that in the flexibility training group (P<0.05). CONCLUSION: The chiropractic plus plum blossom needling combined with flexibility training can improve the attention deficit in mentally-retarded adolescents.

Pancoast Tumor Presenting as Neck Pain in the Chiropractic Office: A Case Report and Literature Review.

BACKGROUND Pancoast tumors, also called superior sulcus tumors, are a rare type of cancer affecting the lung apex. These tumors can spread to the brachial plexus and spine and present with symptoms that appear to be of musculoskeletal origin. CASE REPORT A 59-year-old Asian man presented to a chiropractor in Hong Kong with a 1-month history of neck and shoulder pain and numbness that had been treated unsuccessfully with exercise, medications, and acupuncture. He had an active history of tuberculosis, which was currently treated with antibiotics, and a 50-pack-year history of smoking. Cervical magnetic resonance imaging (MRI) was performed urgently, revealing a small cervical disc herniation thought to correspond with radicular symptoms. However, as the patient did not respond to a brief trial of care, a thoracic MRI was urgently ordered, revealing a large superior sulcus tumor invading the upper to mid-thoracic spine. The patient was referred for medical care and received radiotherapy and chemotherapy with a positive outcome. A literature review identified 6 previously published cases in which a patient presented to a chiropractor with an undiagnosed Pancoast tumor. All patients had shoulder, spine, and/or upper extremity pain. CONCLUSIONS Patients with a previously undiagnosed Pancoast tumor can present to chiropractors given that these tumors may invade the brachial plexus and spine, causing shoulder, spine, and/or upper extremity pain. Chiropractors should be aware of the clinical features and risk factors of Pancoast tumors to readily identify them and refer such patients for medical care.

Patient Concerns and Beliefs Related to Audible Popping Sound and the Effectiveness of Manipulation: Findings From an Online Survey.

OBJECTIVE: The purpose of this study was to assess whether beliefs about the origin of the popping sound and the effects of thrust manipulation (TM) were in agreement with current scientific evidence and whether a practitioner's explanation could influence patient beliefs of theoretical mechanisms. METHODS: A cross-sectional online survey was conducted in Italy from January 7, 2019 to April 20, 2019. The questionnaire was sent to 900 Italian adults through online recruitment, including people with and without a history of manipulation, such as given by physiotherapists, chiropractors, osteopaths, and manual medicine physicians to manage musculoskeletal disorders. The questionnaire consisted of 11 multiple-choice questions and could be completed within 15 weeks. The Likert scale was used to investigate participants' attitudes. Sex and previous experience of TM variables were evaluated using a Student's t-test; a 1-way F analysis of variance test was performed to evaluate age, educational qualification, and the professional who performed the TM. RESULTS: We retrieved 478 questionnaires, including 175 participants with no TM history and 303 with TM history. There were 31% of participants (n = 94) with a history of TM who reported they did not receive explanations regarding manipulation. The participants' beliefs mostly disagreed with the current hypotheses provided by the scientific literature on the theoretical mechanisms of popping sound (tribonucleation and cavitation). There were 9.9% (n = 30) of participants who answered "realignment of bone positional fault" to explain the mechanism behind TM. There was a high degree of agreement with the belief that the popping sound should be present for a successful TM (respectively, 2.8 standard deviation [SD; 1.2] and 2.6 SD [1.2] for TM+ and TM- participants). No statistically significant differences were found between participants with and without a history of TM. CONCLUSION: The participants in this study reported a belief that popping was related to effectiveness of TM. A high percentage of this sample had beliefs about TM mechanisms for the audible popping sound that were inconsistent with current literature. Beliefs were similar between groups, suggesting that instructions given by TM practitioners did not seem to be an influence on these patients' beliefs.

Association between chiropractic care and use of prescription opioids among older medicare beneficiaries with spinal pain: a retrospective observational study.

BACKGROUND: The burden of spinal pain can be aggravated by the hazards of opioid analgesics, which are still widely prescribed for spinal pain despite evidence-based clinical guidelines that identify non-pharmacological therapies as the preferred first-line approach. Previous studies have found that chiropractic care is associated with decreased use of opioids, but have not focused on older Medicare beneficiaries, a vulnerable population with high rates of co-morbidity and polypharmacy. The purpose of this investigation was to evaluate the association between chiropractic utilization and use of prescription opioids among older adults with spinal pain. METHODS: We conducted a retrospective observational study in which we examined a nationally representative multi-year sample of Medicare claims data, 2012-2016. The study sample included 55,949 Medicare beneficiaries diagnosed with spinal pain, of whom 9,356 were recipients of chiropractic care and 46,593 were non-recipients. We measured the adjusted risk of filling a prescription for an opioid analgesic for up to 365 days following diagnosis of spinal pain. Using Cox proportional hazards modeling and inverse weighted propensity scoring to account for selection bias, we compared recipients of both primary care and chiropractic to recipients of primary care alone regarding the risk of filling a prescription. RESULTS: The adjusted risk of filling an opioid prescription within 365 days of initial visit was 56% lower among recipients of chiropractic care as compared to non-recipients (hazard ratio 0.44; 95% confidence interval 0.40-0.49). CONCLUSIONS: Among older Medicare beneficiaries with spinal pain, use of chiropractic care is associated with significantly lower risk of filling an opioid prescription.

Carotid Artery Dissection and Ischemic Stroke Following Cervical Chiropractic Manipulation: Two Case Reports.

OBJECTIVE: Patients can be at risk of carotid artery dissection and ischemic stroke after cervical chiropractic manipulation. However, such risks are rarely reported and raising awareness can increase the safety of chiropractic manipulations. CASE REPORT: We present two middle-aged patients with carotid artery dissection leading to ischemic stroke after receiving chiropractic manipulation in Foshan, Guangdong Province, China. Both patients had new-onset pain in their necks after receiving chiropractic manipulations. Excess physical force during chiropractic manipulation may present a risk to patients. Patient was administered with recombinant tissue plasminogen activator after radiological diagnoses. They were prescribed 100 mg and clopidogrel 75 mg daily for 3 months as dual antiplatelet therapy. There were no complications over the follow-up period. CONCLUSION: These cases suggest that dissection of the carotid artery can occur as the result of chiropractic manipulations. Patients should be diagnosed and treated early to achieve positive outcomes. The safety of chiropractic manipulations should be increased by raising awareness about the potential risks.

Recognition of prodromal cervical spondylotic myelopathy presenting in a U.S. Veteran referred to chiropractic for acute thoracic pain: A case report.

OBJECTIVE: To highlight a patient who was referred to a VA chiropractic clinic for thoracic pain and upon physical exam was found to be myelopathic, subsequently requiring surgery. CLINICAL FEATURES: A 58-year-old male attended a telephone interview with the VA chiropractic clinic for thoracic pain of 4 months duration; he denied neck pain, upper extremity symptoms or clumsiness of the feet or hands. At his in-person visit, he acknowledged frequently dropping items. The physical examination revealed signs of myelopathy including positive Hoffman's bilaterally, 3+ brisk patellar reflexes, and 5+ beats of ankle clonus bilaterally. He also had difficulty walking heel/toe. INTERVENTION AND OUTCOME: Cervical and thoracic radiographs were ordered and a referral was placed to the Physical Medicine and Rehabilitation (PM&R) Clinic for evaluation of the abnormal neurologic exam and suspicion of cervical spondylotic myelopathy (CSM). He was treated for 2 visits in the chiropractic clinic for his thoracic pain, with resolution of thoracic symptoms. No treatment was rendered to the cervical spine. The PM&R physician ordered a cervical MRI which demonstrated severe central canal stenosis and increased T2 signal within the cord at C5-C6, representing myelopathic changes. The PM&R specialist referred him to Neurosurgery which resulted in a C5-6, C6-7 anterior cervical discectomy and fusion. CONCLUSION: The importance of physical examination competency and routine thoroughness cannot be overstated. Swift identification of pathologic signs by the treating chiropractor resulted in timely imaging and surgical intervention.
