Identifying and addressing patient substance use: a survey of chiropractic clinicians.

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.

Thoracolumbar fascia mobility and chronic low back pain: Phase 1 of a pilot and feasibility study assessing repeated measures and the influence of paraspinal muscle contraction.

BACKGROUND: Differential movement, or shear strain (SS), between layers of thoracolumbar fascia is reduced with chronic low back pain. To provide a foundation for clinical research involving SS, this study assessed temporal stability and the effect of paraspinal muscle contraction on SS in persons with chronic low back pain. METHODS: We used ultrasound imaging to measure SS in adults self-reporting low back pain ≥1 year. Images were obtained by placing a transducer 2-3 cm lateral to L2-3 with participants lying prone and relaxed on a table moving the lower extremities downward 15°, for 5 cycles at 0.5 Hz. To assess paraspinal muscle contraction effects, participants raised the head slightly from the table. SS was calculated using 2 computational methods. Method 1 averaged the maximum SS from each side during the third cycle. Method 2 used the maximum SS from any cycle (2-4) on each side, prior to averaging. SS was also assessed after a 4-week no manual therapy period. RESULTS: Of 30 participants (n = 14 female), mean age was 40 years; mean BMI 30.1. Mean (SE) SS in females with paraspinal muscle contraction was 66% (7.4) (method 1) and 78% (7.8) (method 2); 54% (6.9) (method 1) and 67% (7.3) (method 2) in males. With muscles relaxed, mean SS in females was 77% (7.6) (method 1) or 87% (6.8) (method 2); 63% (7.1) (method 1) and 78% (6.4) (method 2) in males. Mean SS decreased 8-13% in females and 7-13% in males after 4-weeks CONCLUSION: Mean SS in females was higher than males at each timepoint. Paraspinal muscle contraction temporarily reduced SS. Over a 4-week no-treatment period, mean SS (with paraspinal muscles relaxed) decreased. Methods less likely to induce muscle guarding and enabling assessment with broader populations are needed.

Thoracolumbar fascia mobility and chronic low back pain: Phase 2 of a pilot and feasibility study including multimodal chiropractic care.

BACKGROUND: Thoracolumbar fascia mobility observed with ultrasound imaging and calculated as shear strain is lower in persons with chronic low back pain. This pilot and feasibility trial assessed thoracolumbar shear strain in persons with chronic low back pain following spinal manipulation and over an 8-week course of multimodal chiropractic care. METHODS: Adults self-reporting chronic low back pain ≥ 1 year participated between September 2019 and April 2021 in a trial using ultrasound imaging to measure thoracolumbar shear strain. Ultrasound imaging occurred 2-3 cm lateral to L2-3 while participants relaxed prone on an automated table moving the lower extremities downward 15 degrees, for 5 cycles at 0.5 Hz. Pain intensity on an 11-point numerical rating scale, disability, pain interference, and global improvement were also collected. Participants received 8-weeks of twice-weekly chiropractic care including spinal manipulation, education, exercise, self-management advice and myofascial therapies. Shear strain was computed using 2 methods. The highest shear strain from movement cycles 2, 3, or 4 was averaged over right and left sides for each participant. Alternately, the highest shear strain from movement cycle 3 was used. All data were analyzed over time using mixed-effects models. Estimated mean changes are reported. RESULTS: Of 20 participants completing 8-weeks of chiropractic care (female n = 11), mean (SD) age was 41 years (12.6); mean BMI was 28.5 (6.2). All clinical outcomes improved at 8-weeks. Mean (95% confidence interval) pain intensity decreased 2.7 points (- 4.1 to - 1.4) for females and 2.1 points (- 3.7 to 0.4) for males. Mean Roland-Morris disability score decreased by 5 points (- 7.2 to - 2.8) for females, 2.3 points (- 4.9 to 0.2) for males. Mean PROMIS pain interference T-score decreased by 8.7 points (- 11.8 to - 5.5) for females, 5.6 points (- 9.5 to - 1.6) for males. Mean shear strain at 8-weeks increased in females 5.4% (- 9.9 to 20.8) or 15% (- 0.5 to 30.6), decreasing in males 6.0% (- 24.2 to 12.2) or 2% (- 21.0 to 16.8) depending on computational method. CONCLUSION: Spinal manipulation does not likely disrupt adhesions or relax paraspinal muscles enough to immediately affect shear strain. Clinical outcomes improved in both groups, however, shear strain only increased in females following 8-weeks of multimodal chiropractic care. Trial registration ClinicalTrials.gov registration is NCT03916705.

A systematic review of chiropractic care for fall prevention: rationale, state of the evidence, and recommendations for future research.

BACKGROUND: Falls in older adults are a significant and growing public health concern. There are multiple risk factors associated with falls that may be addressed within the scope of chiropractic training and licensure. Few attempts have been made to summarize existing evidence on multimodal chiropractic care and fall risk mitigation. Therefore, the broad purpose of this review was to summarize this research to date. BODY: Systematic review was conducted following PRISMA guidelines. Databases searched included PubMed, Embase, Cochrane Library, PEDro, and Index of Chiropractic Literature. Eligible study designs included randomized controlled trials (RCT), prospective non-randomized controlled, observational, and cross-over studies in which multimodal chiropractic care was the primary intervention and changes in gait, balance and/or falls were outcomes. Risk of bias was also assessed using the 8-item Cochrane Collaboration Tool. The original search yielded 889 articles; 21 met final eligibility including 10 RCTs. One study directly measured the frequency of falls (underpowered secondary outcome) while most studies assessed short-term measurements of gait and balance. The overall methodological quality of identified studies and findings were mixed, limiting interpretation regarding the potential impact of chiropractic care on fall risk to qualitative synthesis. CONCLUSION: Little high-quality research has been published to inform how multimodal chiropractic care can best address and positively influence fall prevention. We propose strategies for building an evidence base to inform the role of multimodal chiropractic care in fall prevention and outline recommendations for future research to fill current evidence gaps.

Care Outcomes for Chiropractic Outpatient Veterans (COCOV): a single-arm, pragmatic, pilot trial of multimodal chiropractic care for U.S. veterans with chronic low back pain.

BACKGROUND: Over 25% of veterans seeking care at U.S. Veterans Health Administration facilities have chronic low back pain (LBP), with high rates of mental health comorbidities. The primary objective of this study was to assess the feasibility of participant recruitment, retention, and electronic data collection to prepare for the subsequent randomized trial of multimodal chiropractic care for pain management of veterans with chronic low back pain. The secondary objectives were to estimate effect sizes and variability of the primary outcome and choose secondary outcomes for the full-scale trial. METHODS: This single-arm pilot trial enrolled 40 veterans with chronic LBP at one Veterans Health Administration facility for a 10-week course of pragmatic multimodal chiropractic care. Recruitment was by (1) provider referral, (2) invitational letter from the electronic health record pre-screening, and (3) standard direct recruitment. We administered patient-reported outcome assessments through an email link to REDCap, an electronic data capture platform, at baseline and 5 additional timepoints. Retention was tracked through adherence to the treatment plan and completion rates of outcome assessments. Descriptive statistics were calculated for baseline characteristics and outcome variables. RESULTS: We screened 91 veterans over 6 months to enroll our goal of 40 participants. Seventy percent were recruited through provider referrals. Mean age (range) was 53 (22-79) years and 23% were female; 95% had mental health comorbidities. The mean number of chiropractic visits was 4.5 (1-7). Participants adhered to their treatment plan, with exception of 3 who attended only their first visit. All participants completed assessments at the in-person baseline visit and 80% at the week 10 final endpoint. We had no issues administering assessments via REDCap. We observed clinically important improvements on the Roland-Morris Disability Questionnaire [mean change (SD): 3.6 (6.1)] and on PROMIS® pain interference [mean change (SD): 3.6 (5.6)], which will be our primary and key secondary outcome, respectively, for the full-scale trial. CONCLUSIONS: We demonstrated the feasibility of participant recruitment, retention, and electronic data collection for conducting a pragmatic clinical trial of chiropractic care in a Veterans Health Administration facility. Using the pilot data and lessons learned, we modified and refined a protocol for a full-scale, multisite, pragmatic, National Institutes of Health-funded randomized trial of multimodal chiropractic care for veterans with chronic LBP that began recruitment in February 2021. TRIAL REGISTRATION: ClinicalTrials.gov NCT03254719.

Health-Related Quality of Life Among United States Service Members with Low Back Pain Receiving Usual Care Plus Chiropractic Care vs Usual Care Alone: Secondary Outcomes of a Pragmatic Clinical Trial.

OBJECTIVE: This study examines Patient-Reported Outcome Measurement Information System (PROMIS®)-29 v1.0 outcomes of chiropractic care in a multi-site, pragmatic clinical trial and compares the PROMIS measures to: 1) worst pain intensity from a numerical pain rating 0-10 scale, 2) 24-item Roland-Morris Disability Questionnaire (RMDQ); and 3) global improvement (modified visual analog scale). DESIGN: A pragmatic, prospective, multisite, parallel-group comparative effectiveness clinical trial comparing usual medical care (UMC) with UMC plus chiropractic care (UMC+CC). SETTING: Three military treatment facilities. SUBJECTS: 750 active-duty military personnel with low back pain. METHODS: Linear mixed effects regression models estimated the treatment group differences. Coefficient of repeatability to estimate significant individual change. RESULTS: We found statistically significant mean group differences favoring UMC+CC for all PROMIS®-29 scales and the RMDQ score. Area under the curve estimates for global improvement for the PROMIS®-29 scales and the RMDQ, ranged from 0.79 to 0.83. CONCLUSIONS: Findings from this pre-planned secondary analysis demonstrate that chiropractic care impacts health-related quality of life beyond pain and pain-related disability. Further, comparable findings were found between the 24-item RMDQ and the PROMIS®-29 v1.0 briefer scales.

Promoting the use of a self-management strategy among novice chiropractors treating individuals with spine pain: A mixed methods pilot clustered-clinical trial.

BACKGROUND: The uptake of Self-Management Support (SMS) among clinicians is suboptimal. To date, few studies have tested knowledge translation (KT) interventions to increase the application of SMS in chiropractic teaching clinics. STUDY OBJECTIVE: Evaluate the feasibility of implementing a KT intervention to promote the use of a SMS strategy among chiropractic interns, their supervisors, and individuals with spine pain compared to controls. METHODS: Mixed methods pilot clustered-clinical trial. Clusters of 16 Patient Management Teams were allocated to a complex KT intervention (online and workshop training). Primary feasibility outcomes for clinicians, interns and patients were rates of recruitment, retention, and adherence to protocol. A nominal group technique and interviews were used to seek end-users' views on the implementation process, and generate possible solutions. RESULTS: In total, 16 (84%) clinicians, 65 (26%) interns and 42 patients agreed to participate. All clinicians in the intervention group completed all KT intervention components, 23 interns (85%) completed the online training and 14 interns (51.8%) attended the workshop training. All clinicians in the intervention and seven (78%) in the control group completed all outcome measures at baseline and 6-month follow-up, while 15 (55.6%) and 23 (60.5%) interns in the intervention and control groups completed the questionnaires at baseline and 6-month follow-up, respectively. Among patients, 10 (52.6%) and 12 (52.2%) in the intervention and control groups respectively completed the questionnaires at the end of the study. Based on interview findings, solutions to improve the feasibility of conducting a full trial include: making SMS a part of the internship, changing the time of introducing the study to the interns, and having more training on SMS. CONCLUSION: Recruitment and retention of chiropractic interns and patients for a larger implementation trial in a single outpatient teaching clinic may be challenging.

Care Outcomes for Chiropractic Outpatient Veterans (COCOV): a qualitative study with veteran stakeholders from a pilot trial of multimodal chiropractic care.

BACKGROUND: Low back pain (LBP) is common among military veterans seeking treatment in Department of Veterans Affairs (VA) healthcare facilities. As chiropractic services within VA expand, well-designed pragmatic trials and implementation studies are needed to assess clinical effectiveness and program uptake. This study evaluated veteran stakeholder perceptions of the feasibility and acceptability of care delivery and research processes in a pilot trial of multimodal chiropractic care for chronic LBP. METHODS: The qualitative study was completed within a mixed-method, single-arm, pragmatic, pilot clinical trial of chiropractic care for LBP conducted in VA chiropractic clinics. Study coordinators completed semi-structured, in person or telephone interviews with veterans near the end of the 10-week trial. Interviews were audiorecorded and transcribed verbatim. Qualitative content analysis using a directed approach explored salient themes related to trial implementation and delivery of chiropractic services. RESULTS: Of 40 participants, 24 completed interviews (60% response; 67% male gender; mean age 51.7 years). Overall, participants considered the trial protocol and procedures feasible and reported that the chiropractic care and recruitment methods were acceptable. Findings were organized into 4 domains, 10 themes, and 21 subthemes. Chiropractic service delivery domain encompassed 3 themes/8 subthemes: scheduling process (limited clinic hours, scheduling future appointments, attendance barriers); treatment frequency (treatment sufficient for LBP complaint, more/less frequent treatments); and chiropractic clinic considerations (hire more chiropractors, including female chiropractors; chiropractic clinic environment; patient-centered treatment visits). Outcome measures domain comprised 3 themes/4 subthemes: questionnaire burden (low burden vs. time-consuming or repetitive); relevance (items relevant for LBP study); and timing and individualization of measures (questionnaire timing relative to symptoms, personalized approach to outcomes measures). The online data collection domain included 2 themes/4 subthemes: user concerns (little difficulty vs. form challenges, required computer skills); and technology issues (computer/internet access, junk mail). Clinical trial planning domain included 2 themes/5 subthemes: participant recruitment (altruistic service by veterans, awareness of chiropractic availability, financial compensation); and communication methods (preferences, potential barriers). CONCLUSIONS: This qualitative study highlighted veteran stakeholders' perceptions of VA-based chiropractic services and offered important suggestions for conducting a full-scale, veteran-focused, randomized trial of multimodal chiropractic care for chronic LBP in this clinical setting. TRIAL REGISTRATION: ClinicalTrials.gov NCT03254719.

Optimizing the Impact of Pragmatic Clinical Trials for Veteran and Military Populations: Lessons From the Pain Management Collaboratory.

Pragmatic clinical trials (PCTs) are well-suited to address unmet healthcare needs, such as those arising from the dual public health crises of chronic pain and opioid misuse, recently exacerbated by the COVID-19 pandemic. These overlapping epidemics have complex, multifactorial etiologies, and PCTs can be used to investigate the effectiveness of integrated therapies that are currently available but underused. Yet individual pragmatic studies can be limited in their reach because of existing structural and cultural barriers to dissemination and implementation. The National Institutes of Health, Department of Defense, and Department of Veterans Affairs formed an interagency research partnership, the Pain Management Collaboratory. The partnership combines pragmatic trial design with collaborative tools and relationship building within a large network to advance the science and impact of nonpharmacological approaches and integrated models of care for the management of pain and common co-occurring conditions. The Pain Management Collaboratory team supports 11 large-scale, multisite PCTs in veteran and military health systems with a focus on team science with the shared aim that the "whole is greater than the sum of the parts." Herein, we describe this integrated approach and lessons learned, including incentivizing all parties; proactively offering frequent opportunities for problem-solving; engaging stakeholders during all stages of research; and navigating competing research priorities. We also articulate several specific strategies and their practical implications for advancing pain management in active clinical, "real-world," settings.

Characteristics of Chiropractic Patients in the Veterans Health Administration During the COVID-19 Pandemic: A Cross-Sectional Analysis.

OBJECTIVE: The purpose of this study was to determine whether patient characteristics were associated with face-to-face (F2F) and telehealth visits for those receiving chiropractic care for musculoskeletal conditions in the US Veterans Health Administration (VHA) during the COVID-19 pandemic. METHODS: A retrospective cross-sectional analysis of all patients (veterans, dependents, and spouses) who received chiropractic care nationwide at the VHA from March 1, 2020, to February 28, 2021, was performed. Patients were allocated into 1 of the following 3 groups: only telehealth visits, only F2F visits, and combined F2F and telehealth visits. Patient characteristics included age, sex, race, ethnicity, marital status, and Charlson Comorbidity Index. Multinomial logistic regression estimated associations of these variables with visit type. RESULTS: The total number of unique patients seen by chiropractors between March 2020 and February 2021 was 62 658. Key findings were that patients of non-White race and Hispanic or Latino ethnicity were more likely to attend telehealth-only visits (Black [odds ratio 1.20, 95% confidence interval {1.10-1.31}], other races [1.36 {1.16-1.59}], and Hispanic or Latino [1.35 {1.20-1.52}]) and combination telehealth and F2F care (Black [1.32 {1.25-1.40}], other races [1.37 {1.23-1.52}], and Hispanic or Latino [1.63 {1.51-1.76}]). Patients younger than 40 years of age were more likely to choose telehealth visits ([1.13 {1.02-1.26}], 66-75 years [1.17 {1.01-1.35}], and >75 years [1.26 {1.06-1.51}] vs those 40-55 years of age). Sex, visit frequency, and Charlson Comorbidity Index showed significant relationships as well, while marital status did not. CONCLUSION: During the COVID-19 pandemic, VHA patients with musculoskeletal complaints using chiropractic telehealth were more ethnically and racially diverse than those using F2F care alone.

Risk of Treatment Escalation in Recipients vs Nonrecipients of Spinal Manipulation for Musculoskeletal Cervical Spine Disorders: An Analysis of Insurance Claims.

OBJECTIVE: The purpose of this study was to evaluate the relationship between treatment escalation and spinal manipulation in a retrospective cohort of people diagnosed with musculoskeletal disorders of the cervical spine. METHODS: We used retrospective analysis of insurance claims data (2012-2018) from a single Fortune 500 company. After isolating the first episode of care, we categorized 58 147 claims into 7951 unique patient episodes. Treatment escalation included claims where imaging, injection, emergency room, or surgery was present. Modified Poisson regression was used to determine the relative risk of treatment escalation comparing recipients vs nonrecipients of spinal manipulation, adjusted for age, sex, episode duration, and risk scores. RESULTS: The sample was 55% women, with a mean age of 44 years (range, 18-103). Treatment escalation was present in 42% of episodes overall: 2448 (46%) associated with other care and 876 (26%) associated with spinal manipulation. The estimated risk of any treatment escalation was 2.38 times higher in those who received other care than in those who received spinal manipulation (95% confidence interval, 2.22-2.55, P = .001). CONCLUSION: Among episodes of care associated with neck pain diagnoses, those associated with other care had twice the risk of any treatment escalation compared with those associated with spinal manipulation. In the United States, over 90% of spinal manipulation is provided by doctors of chiropractic; therefore, these findings are relevant and should be considered in addressing solutions for neck pain. Additional research investigating the factors influencing treatment escalation is necessary to moderate the use of high-cost and guideline-incongruent procedures in people with neck pain.

Patient-Reported Physician Treatment Recommendations and Compliance Among U.S. Adults with Low Back Pain.

Objectives: Numerous recently published clinical care guidelines, including the 2017 American College of Physicians (ACP) Guideline for Low Back Pain (LBP), call for nonpharmacological approaches to pain management. However, little data exist regarding the extent to which these guidelines have been adopted by patients and medical doctors. The study objective was to determine patient-reported treatment recommendations by medical doctors for LBP and patient compliance with those recommendations. Design: This study used a cross-sectional web and mail survey. Settings/Location: The study was conducted among Gallup Panel members across the United States. Subjects: Survey participants included 5377 U.S. adults randomly selected among Gallup Panel members. Of those, 545 reported a visit to a medical doctor within the past year for low back pain and were asked a series of follow-up questions regarding treatment recommendations. Interventions: Participants were asked about medical doctor recommendations for both drug (acetaminophen, nonsteroidal anti-inflammatory drugs [NSAIDs], opioids, benzodiazepines, Gabapentin, Neurontin, and cortisone injections) and nondrug (self-care treatments, massage, acupuncture, spinal manipulation, and physical therapy) treatments. Outcome Measures: Participants were asked to indicate if their medical doctor recommended each drug and nondrug therapy for their LBP and if they had followed each of those treatment recommendations. Results: Ninety-six percent of patients who visited a medical doctor for LBP received a recommendation for one or more pain treatments, with 81% reporting that their medical doctor recommended both drug and nondrug therapies. Seventy-six percent of respondents were recommended acetaminophen or NSAIDs, 79% were recommended self-care treatments, 37% were recommended massage, acupuncture, or spinal manipulation, and 60% were recommended physical therapy. Nearly two-thirds of our sample reported that their doctor had recommended prescription medications, including opioids, benzodiazepines, Gabapentin, Neurontin, or cortisone injections. Reported adherence to treatment recommendations ranged from 68% for acupuncture to 94% for NSAIDs. Conclusions: One year after publication of the ACP's Guideline on LBP, patients report that medical doctors recommended both pharmacological and nonpharmacological treatment approaches to patients with LBP. In the majority of cases, a combination of prescription medications and self-care were recommended, illustrating the need for additional research on the effectiveness of multi-modal treatment strategies. Patients reported that they were largely compliant with medical doctor recommendations, underscoring the influence that medical doctors have in directing patient care for LBP. These findings indicate that further work is also needed to explore the impact of personal experience, training, clinical evidence, sociocultural factors, and health plans on medical doctors therapeutic recommendations in the context of back pain.

Characteristics and Practice Patterns of U.S. Veterans Health Administration Doctors of Chiropractic: A Cross-sectional Survey.

OBJECTIVE: The purpose of this study was to survey U.S. Veterans Health Administration (VA) chiropractors to assess current demographic and professional characteristics, including practice parameters, interprofessional collaboration, academic experience, and scholarly activity. METHODS: A cross-sectional survey was performed from August 21, 2019, to September 6, 2019, including all chiropractors identified with any VA appointment. REDCap software was used to conduct the survey. Data from surveys were exported to Microsoft Excel for data analysis. RESULTS: Of the 177 providers solicited, 118 returned completed surveys (67% response rate). Respondents predominantly self-reported as white (84%) and male (77.1%), with a mean age of 47 years, and reported spending at least 75% of time on clinical care. Most respondents reported being VA employees (96%) with full-time appointments (94%). Approximately half reported having prior hospital training (48%), supervising chiropractic students (53%) and students in other health professions (47%), and authoring or coauthoring ≥1 peer-reviewed publications (42%). Respondents reported performing an average of 6 to 15 new-patient consultations and 31 to 60 follow-up visits per week. Most patient referrals to chiropractic care originated from primary care providers, with low back conditions without radiculopathy as the most frequently seen condition. Diversified manipulation and flexion-distraction techniques, along with myofascial therapies, therapeutic exercises, and self-management advice, were the most commonly reported interventions. CONCLUSION: We report provider and practice characteristics from chiropractors working in a large, integrated health care system. Most are full-time employees, work in physical medicine departments, and have held their position for up to 5 years. The majority of respondents report diagnostic and treatment approaches concordant with current clinical practice guidelines.

Chiropractic Services and Diagnoses for Low Back Pain in 3 U.S. Department of Defense Military Treatment Facilities: A Secondary Analysis of a Pragmatic Clinical Trial.

OBJECTIVE: The purpose of this study was to describe the diagnoses and chiropractic services performed by doctors of chiropractic operating within 3 military treatment facilities for patients with low back pain (LBP). METHODS: This was a descriptive secondary analysis of a pragmatic clinical trial comparing usual medical care (UMC) plus chiropractic care to UMC alone for U.S. active-duty military personnel with LBP. Participants who were allocated to receive UMC plus 6 weeks of chiropractic care and who attended at least 1 chiropractic visit (n = 350; 1547 unique visits) were included in this analysis. International Classification of Diseases and Current Procedural Terminology codes were transcribed from chiropractic treatment paper forms. The number of participants receiving each diagnosis and service and the number of each service on unique visits was tabulated. Low back pain and co-occurring diagnoses were grouped into neuropathic, nociceptive, bone and/or joint, general pain, and nonallopathic lesions categories. Services were categorized as evaluation, active interventions, and passive interventions. RESULTS: The most reported pain diagnoses were lumbalgia (66.1%) and thoracic pain (6.6%). Most reported neuropathic pain diagnoses were sciatica (4.9%) and lumbosacral neuritis or radiculitis (2.9%). For the nociceptive pain, low back sprain and/or strain (15.8%) and lumbar facet syndrome (9.2%) were most common. Most reported diagnoses in the bone and/or joint category were intervertebral disc degeneration (8.6%) and spondylosis (6.0%). Tobacco use disorder (5.7%) was the most common in the other category. Chiropractic care was compromised of passive interventions (94%), with spinal manipulative therapy being the most common, active interventions (77%), with therapeutic exercise being most common, and a combination of passive and active interventions (72%). CONCLUSION: For the sample in this study, doctors of chiropractic within 3 military treatment facilities diagnosed, managed, and provided clinical evaluations for a range of LBP conditions. Although spinal manipulation was the most commonly used modality, chiropractic care included a multimodal approach, comprising of both active and passive interventions a majority of the time.

Changes in the Use of Telehealth and Face-To-Face Chiropractic Care in the Department of Veterans Affairs Before and After the COVID-19 Pandemic.

OBJECTIVE: The purpose of this study was to describe the use of face-to-face and telehealth chiropractic care in the U.S. Veterans Health Administration (VHA) before and after the declaration of the COVID-19 pandemic. METHODS: A cross-sectional study was performed of VHA administrative data, including monthly numbers of unique patients and visits for face-to-face and telehealth (synchronous video or telephone) chiropractic care from October 1, 2019, to March 31, 2021. RESULTS: During the pre-pandemic phase (October 2019 to February 2020), a mean of 28 930 (SD 289) total monthly visits were conducted face-to-face (99.9%). In March 2020, total monthly visits decreased to 17.0% of the pre-pandemic average, 25.0% being face-to-face, with over a 200-fold increase in telehealth visits (rising to 1331 visits) compared to the pre-pandemic average. April showed the lowest number of face-to-face visits at (4094). May-October 2020 showed that face-to-face visits increase on average by 70.7% per month, while telehealth visits averaged 17.3% per month. October-February 2020 had total monthly visits plateau at a mean of 22 250 (76.9% of the pre-pandemic average). Telehealth visits reduced to a mean of 1245 monthly visits over this 5-month period, a drop of -5.6% of the average of monthly visits. In March 2021, total monthly visits (31 221) exceeded the pre-pandemic average for the first time since January 2020; 4.0% remained in telehealth. CONCLUSION: Face-to-face visits decreased early in the pandemic but increased after May 2020. Chiropractic telehealth use rapidly increased during the early stage of the COVID-19 pandemic, and decreased later, but remained slightly higher than pre-pandemic levels.

Multimodal chiropractic care for migraine: A pilot randomized controlled trial.

BACKGROUND: Spinal manipulation may reduce migraine frequency, but effects of multimodal chiropractic care on migraine frequency have not been evaluated. METHODS: We conducted a pilot randomized controlled trial comparing multimodal chiropractic care + enhanced usual care (MCC+) versus enhanced usual care alone (EUC) among adult women with episodic migraine. EUC was comprised of usual medical care and migraine education literature. MCC+ participants received 10 sessions of chiropractic care over 14 weeks. Primary aims evaluated feasibility of recruitment, retention, protocol adherence, and safety. Change in migraine days was a secondary aim. RESULTS: Of 422 patients screened, 61 were randomized over 20 months. Fifty-seven (93%) completed daily migraine logs during the intervention, 51 (84%) completed final follow-up, and 45 (74%) completed all assessments. Twenty-four of 29 MCC+ participants (83%) attended > 75% of the chiropractic sessions. Ninety-eight non-serious adverse events were reported by 26 participants (43%) with 39 events among 11 EUC participants and 59 events among 15 MCC+ participants. MCC+ participants experienced greater reductions in migraine days (-2.9 days for MCC+ vs. -1.0 days for EUC, difference = -1.9; 95% confidence interval: -3.5, -0.4). CONCLUSIONS: Pre-specified feasibility criteria were not met, but deficits were remediable. Preliminary data support a definitive trial of MCC+ for migraine. TRIAL REGISTRATION: This study is registered at Clinicaltrials.gov (NCT03177616).

Veteran Response to Dosage in Chiropractic Therapy (VERDICT): Study Protocol of a Pragmatic Randomized Trial for Chronic Low Back Pain.

BACKGROUND: Low back pain is a leading cause of disability in veterans. Chiropractic care is a well-integrated, nonpharmacological therapy in Veterans Affairs health care facilities, where doctors of chiropractic provide therapeutic interventions focused on the management of low back pain and other musculoskeletal conditions. However, important knowledge gaps remain regarding the effectiveness of chiropractic care in terms of the number and frequency of treatment visits needed for optimal outcomes in veterans with low back pain. DESIGN: This pragmatic, parallel-group randomized trial at four Veterans Affairs sites will include 766 veterans with chronic low back pain who are randomly allocated to a course of low-dose (one to five visits) or higher-dose (eight to 12 visits) chiropractic care for 10 weeks (Phase 1). After Phase 1, participants within each treatment arm will again be randomly allocated to receive either monthly chiropractic chronic pain management for 10 months or no scheduled chiropractic visits (Phase 2). Assessments will be collected electronically. The Roland Morris Disability Questionnaire will be the primary outcome for Phase 1 at week 10 and Phase 2 at week 52. SUMMARY: This trial will provide evidence to guide the chiropractic dose in an initial course of care and an extended-care approach for veterans with chronic low back pain. Accurate information on the effectiveness of different dosing regimens of chiropractic care can greatly assist health care facilities, including Veterans Affairs, in modeling the number of doctors of chiropractic that will best meet the needs of patients with chronic low back pain.

Effects of Chiropractic Care on Strength, Balance, and Endurance in Active-Duty U.S. Military Personnel with Low Back Pain: A Randomized Controlled Trial.

Objectives: To investigate whether chiropractic care influences strength, balance, and/or endurance in active-duty United States military personnel with low back pain (LBP). Design: This study employed a prospective randomized controlled trial using a pragmatic treatment approach. Participants were randomly allocated to 4 weeks of chiropractic care or to a wait-list control. Interventions: Chiropractic care consisted of spinal manipulation, education, advice, and reassurance. Settings/Location: Naval Air Technical Training Center branch clinic at the Naval Hospital Pensacola Florida. Subjects: One hundred ten active-duty military personnel 18-40 years of age with self-reported LBP. Outcome measures: Isometric pulling strength from a semisquat position was the primary outcome. Secondary outcomes were single-leg balance with eyes open and eyes closed, and trunk muscle endurance using the Biering-Sorensen test. Patient-reported outcomes such as pain severity and disability were also measured. Outcomes were measured at baseline and 4 weeks. Linear mixed-effects regression models over baseline and 4 weeks were used for analysis. Results: Participants had mean age of 30 years (18-40), 17% were female, 33% were non-white, and 86% reported chronic LBP. Mean maximum pulling strength in the chiropractic group increased by 5.08 kgs and decreased by 7.43 kgs in the wait-list group, with a statistically significant difference in mean change between groups (p = 0.003). Statistically significant differences in mean change between groups were also observed in trunk muscle endurance (13.9 sec, p = 0.002) and balance with eyes closed (0.47 sec, p = 0.01), but not in balance with eyes open (1.19 sec, p = 0.43). Differences in mean change between groups were statistically significant in favor of chiropractic for LBP-related disability, pain intensity and interference, and fear-avoidance behavior. Conclusions: Active-duty military personnel receiving chiropractic care exhibited improved strength and endurance, as well as reduced LBP intensity and disability, compared with a wait-list control.

Promoting the use of self-management in patients with spine pain managed by chiropractors and chiropractic interns: barriers and design of a theory-based knowledge translation intervention.

Background: The literature supports the effectiveness of self-management support (SMS) to improve health outcomes of patients with chronic spine pain. However, patient engagement in SMS programs is suboptimal. The objectives of this study were to: 1) assess participation in self-care (i.e. activation) among patients with spine pain, 2) identify patients' barriers and enablers to using SMS, and 3) map behaviour change techniques (BCTs) to key barriers to inform the design of a knowledge translation (KT) intervention aimed to increase the use of SMS. Methods: In summer 2016, we invited 250 patients with spine pain seeking care at the Canadian Memorial Chiropractic College in Ontario, Canada to complete the Patient Activation Measure (PAM) survey to assess the level of participation in self-care. We subsequently conducted individual interviews, in summer 2017, based on the Theoretical Domains Framework (TDF) in a subset of patients to identify potential challenges to using SMS. The interview guide included 20 open-ended questions and accompanying probes. Findings were deductively analysed guided by the TDF. A panel of 7 experts mapped key barriers to BCTs, designed a KT intervention, and selected the modes of delivery. Results: Two hundred and twenty-three patients completed the PAM. Approximately 24% of respondents were not actively involved in their care. Interview findings from 13 spine pain patients suggested that the potential barriers to using SMS corresponded to four TDF domains: Environmental Context and Resources; Emotion; Memory, Attention & Decision-Making; and Behavioural Regulation. The proposed theory-based KT intervention includes paper-based educational materials, webinars and videos, summarising and demonstrating the therapeutic recommendations including exercises and other lifestyle changes. In addition, the KT intervention includes Brief Action Planning, a SMS strategy based on motivational interviewing, along with a SMART plan and reminders. Conclusions: Almost one quarter of study participants were not actively engaged in their spine care. Key barriers likely to influence uptake of SMS among patients were identified and used to inform the design of a theory-based KT intervention to increase their participation level. The proposed multi-component KT intervention may be an effective strategy to optimize the quality of spine pain care and improve patients' health-outcomes.

Role for Endocannabinoids in Spinal Manipulative Therapy Analgesia?

Chronic pain is quite prevalent and causes significant disabilities and socioeconomic burdens. Spinal manipulative therapy and other manipulative therapies are used to manage chronic pain. There is a critical knowledge gap about mechanisms and sites of action in spinal manipulative therapy pain relief, especially the short-term analgesia that occurs following a treatment. Endocannabinoids are an activity-dependent neurotransmitter system that acts as a short-term synaptic circuit breaker. This review describes both clinical research and basic research evidence suggesting that endocannabinoids contribute to short-term manipulative therapy analgesia. Determining endocannabinoids involvement in spinal manipulative therapy will improve its clinical efficacy when results from basic science and clinical research are translated.
