Background: Low back pain (LBP) is common among older adults, and it is a frequent reason for seeking chiropractic care. The STarT Back Screening Tool (SBT) was developed to stratify patients with LBP into low, medium, and high-risk treatment pathways, so that the treatment can be matched to each participant's risk profile. But its prognostic performance varies across settings and populations. No studies have focused on the SBT's utility as a stratified-care tool in older adults with LBP in a chiropractic setting. Therefore, our aim was to evaluate the ability of the SBT to predict three-, six-, and 12-month disability and pain outcomes in older adults (≥55 years) with a new episode of LBP consulting chiropractors in the Netherlands, Sweden, and Australia.

Methods: This was a secondary analysis of the Back Complaints in Older Adults - Chiropractic (BACE-C) cohort. Participants visiting chiropractors with LBP completed baseline questionnaires for demographic and clinical characteristics, including the SBT. Follow-up questionnaires assessed disability (Roland Morris Disability Questionnaire (RMDQ)) and pain intensity (11-point Numerical Rating Scale (NRS)). "No improvement" on disability and pain intensity was defined as less than 30% reduction in baseline scores. We used logistic regression models to estimate discrimination metrics including the area under the receiver operating characteristic curve (AUC). Subgroup analyses were conducted by country, sex, and LBP duration; sensitivity analyses employed alternative "no improvement" definitions and linear regression on continuous outcome scores.

Results: A total of 738 participants were included. The mean age of the study sample was 66.2 ± 7.5 years and 50.9% of the participants were female. The SBT showed poor discrimination for predicting no improvement in disability and pain intensity. All AUC values were below 0.60 regardless of whether SBT risk subgroups (i.e. low/medium/high) or the SBT sum score were used. Subgroup and sensitivity analyses did not meaningfully improve discrimination.

Conclusion: The SBT presented limited prognostic ability to predict outcomes of disability and pain intensity in older adults with LBP in a chiropractic setting. These findings suggest insufficient evidence for the prognostic ability of the SBT risk stratification tool. Future research should explore reasons behind the limited prognostic accuracy and consider potential modifications or alternative tools.

Background: Chronic low back pain is a prevalent condition that impairs productivity and quality of life. While spinal manipulative therapy reduces pain and disability, the biomechanical mechanisms underlying these effects remain unclear. This study utilized diagnostic ultrasound to measure lumbo-sacral spinous process movement (L3-S1) during Cox^® Flexion Distraction manipulation, Protocol I, providing insight into spinal intersegmental motion.

Methods: This study analyzed a convenience sample of generally healthy participants, aged 21 years and older, from both sexes and various ethnicities who reported no back pain. Participants were recruited through announcements and flyers posted around the Keiser university campus. Data was collected from June-August 2022. The participants were positioned prone on a specialized flexion distraction chiropractic table. Ultrasound imaging was performed to measure the spinous process distance from L3-S1 before the procedure, during flexion distraction utilizing standard Protocol I, and post-procedure. Ultrasound measurements were recorded by identifying the tips of the spinous processes and distances between L3-L4, L4-L5, and L5-S1, before, during, and after flexion distraction. Statistical analyses included paired t-tests to evaluate spinous process distances pre- and during Cox^® Flexion distraction, independent t-tests for gender differences, and linear regression for body mass index (BMI) and age correlations with changes in separation distance.

Results: Thirty participants (16 male, 14 female) with a mean age of 32.5 years (Standard deviation [SD] 10.4), mean weight of 69.2 Kg (SD 11.8), mean height of 169.0 cm (SD 8.9), and BMI of 23.9 underwent Cox^® Flexion Distraction Protocol I. Spinous process separation increased during treatment: L3-L4 (0.13 mm), L4-L5 (0.13 mm), and L5-S1 (0.16 mm). Paired ttests showed significant pre- and during-treatment changes (p < 0.001), with moderate correlations to BMI (R²=0.61) and age (R²=0.58). Gender differences did not reveal statistical differences in separation distances at all lumbar levels measured (p > 0.1).

Conclusion: Ultrasound imaging revealed significant separation of spinous processes at L3-L4, L4-L5, and L5-S1 during Cox^® Flexion Distraction Protocol I. Statistical analyses showed separation correlated moderately with age and BMI that was unaffected by gender. Future studies should assess this technique's relevance in patients with low back pain.

Background: Rising low back pain (LBP) prevalence and increased patient reliance on online health resources necessitate critically evaluating how chiropractic websites represent common musculoskeletal conditions. This study analyzed LBP-related content shared by South African chiropractic websites to assess the credibility of available information.

Methods: A cross-sectional content evaluation was conducted between 2 June 2024 and 21 July 2024 on 333 South African chiropractic websites, identified using a Google search cross-referenced with the Allied Health Professions Council of South Africa registry. Four key areas were evaluated, including (1) contributors to, (2) diagnostic approaches for, (3) possible treatment approaches for and 4) indicators for seeking professional treatment for LBP. Sociodemographic factors such as educational background, sex, and practice ownership structure were considered. A pilot ensured data collection standardization. Content and statistical analysis explored information, citation frequency and identified trends in chiropractic online health communication.

Results: The analysis revealed significant variability of LBP-related content across chiropractic websites. Of the 333 websites analyzed, most chiropractors were trained at UJ (58.1%) and DUT (29.2%). Sex distribution showed 55.3% were female-owned. The highest concentration of chiropractic websites was in Gauteng, the Western Cape, and KwaZulu-Natal. Regarding the 4 key areas, mechanical contributors to LBP were predominant (65.2%), diagnostic approaches (56.7%), treatment approaches (79.6%) and explicit guidance on when to seek care (47.4%) was mentioned in the websites. Only 13.5% of websites cite sources of the information shared. Chiropractors trained at UJ and DUT emphasized evidence-based treatments, while those trained internationally referenced alternative methods. Sex differences showed males focusing on diagnostic tools and treatment protocols, while females emphasized holistic care and lifestyle modifications.

Conclusion: This study highlights the need for improved LBP information quality and consistency on South African chiropractic websites. The structured subjective content evaluation revealed notable gaps in content depth, specificity, and evidence-based citations. Sociodemographic factors, including educational background and sex, influenced the presentation of information. Future research should prioritize developing standardized and evidence-based guidelines for chiropractic websites to improve access to online health information and patient education and ensure accurate, reliable health information delivery.

Lumbar spinal stenosis is a growing problem among older adults, associated with significant disability and socio-economic burden. Neurogenic claudication is the most common clinical syndrome caused by LSS with pain being the predominant symptom and limited walking the main impairment. Lumbar spinal stenosis can also impact sexual function in older adults, necessitating greater awareness of this association. Pain and impaired function can lead to psychosocial distress, including hopelessness, anxiety, and isolation, further compounding disability. Recent clinical practice guidelines recommend non-operative treatment as the first-line approach, including manual therapy, exercise, and education. However, these guidelines lack details on the practical application of these interventions in clinical practice. This narrative review explores the epidemiology of lumbar spinal stenosis, the evidence supporting non-operative care, and practical management strategies. It also highlights the relationship between sexual dysfunction and lumbar spinal stenosis.

Purpose: Chronic non-specific low back pain (CNLBP) is a complex and heterogeneous condition, and it is necessary to explore new treatment approaches. We evaluated whether the addition of dry cupping therapy to guideline‑based conventional therapy would further improve clinical outcomes in CNLBP.

Methods: Thirty-six patients with CNLBP were recruitedand randomly divided into two groups: the control group and the intervention group. The intervention group received cupping therapy in addition to the control group (core stabilization exercises, spinal manipulation and education) for 4 weeks. The primary outcome was the visual analog scale (VAS) for pain intensity. Secondary outcomes were the Roland Morris disability questionnaire (RMDQ), and pressure pain thresholds (PPT) at bilateral Shenshu (BL23), Qihaishu (BL24), and Dachangshu (BL25) acupuncture points.

Results: At week 4 the between‑group difference in resting pain was trivial (median difference 0.0 cm, 95% CI - 1.0 to 1.0). Neither clinically important nor statistically significant differences were detected in disability or PPTs. Both groups improved substantially from baseline.

Conclusion: In this randomized trial, adding dry cupping to conventional therapy offered no additional benefit over conventional therapy alone for pain, disability or PPT in CNLBP. Larger, multicentre trials with longer follow‑up and standardized negative pressures are warranted.

Background: Manual therapy, including high-velocity low-amplitude spinal manipulation (HVLA-SM), is a complex motor task performed by trained individuals. The ability to modulate the magnitude of applied forces is an attribute of proficiency that is challenging for providers and students. Adopting different biomechanical strategies may facilitate force modulation by practitioners performing HVLA-SM. This study evaluated the efficacy of different biomechanical strategies on force-time characteristics of prone thoracic HVLA-SM.

Methods: A randomized crossover experimental design was used. Data were collected between October 2022 and May 2023 from chiropractic students at the Canadian Memorial Chiropractic College who performed HVLA-SM targeted to the thoracic spine of a prone-lying manikin using as much force as possible in each of six different strategies. Strategies (S1 to S6) were specifically developed to successively increase a person's ability to produce force while performing HVLA-SM. Force-time parameters for the HVLA-SM trials were recorded. Peak force was the primary outcome of interest while preload force, load rate, and time to peak force were analyzed as secondary measures.

Results: Data were collected from 97 participants (51 female). Peak force increased successively from S1 to S5 with moderate effects (- 0.45 ≤ effect size ≤ -0.72). There was no statistical difference in either peak force or load rate between S5 and S6. Load rate also did not statistically increase between S3 and S4 where different muscle groups were targeted to produce force. The strategy with the highest peak force (S6) also demonstrated the lowest preload force.

Conclusions: Strategies used in this study effectively facilitated modulation of force-time characteristics of prone thoracic HVLA-SM. Thus, training approaches may consider introducing people to different biomechanical strategies to enhance HVLA-SM force modulation.

Background: In the realm of biomedical research articles, authors typically utilize descriptive statistics to outline the characteristics of their study samples. The standard deviation (SD) serves to illustrate variability among the individuals in a sample, whereas the standard error of the mean (SEM) conveys the level of uncertainty associated with the sample mean's representation of the population mean. It is not unusual for authors of scientific articles to incorrectly utilize the SEM rather than the SD when explaining data variability. This is problematic because the SEM is consistently smaller than the SD, which could cause readers to underestimate variation in the data. In medical journals, inappropriate use has been found in 14-64% of articles. Moreover, in the field of musculoskeletal health and manual medicine, there is a noticeable absence of literature on the appropriate presentation of statistics.

Aim: The aim of this study was to map the frequency of inappropriate reporting of SEM in articles published over a three-year period in three prominent journals in manual medicine.

Methods: In this critical analysis, all articles in three journals - BMC Chiropractic and Manual Therapies (CMT), Journal of Manipulative and Physiological Therapeutics (JMPT) and Musculoskeletal Science and Practice: An International Journal of Musculoskeletal Physiotherapy (MSP) - published between 2017 and 2019 were analysed based on descriptive statistics that inappropriately or vaguely reported SEMs.

Results: In total, 790 articles were analysed from the three journals, 487 of which were found to report the SEM. Among these articles, we identified a frequency of 1.4% of inadequate SEM use. The investigation also showed that in 2.5% of the cases, authors did not clarify whether the ± sign presented in text, tables or figures expressed SDs or SEMs.

Conclusion: There was a low frequency (1.4%) of inaccurately reported SEMs in scientific journals focusing on manual medicine, which was notably lower than studies conducted in other fields. Additionally, it was noted that in 2.5% of the articles, the ± sign was not adequately defined, which could lead to confusion among readers and hinder the interpretation of the results.

Background: Exercise therapy and education are first-line care for those with chronic low back pain (CLBP), but information on its applicability in older adults is limited, and adherence to non-pharmacological treatments in this population is challenging. This study explored perspectives of older adults with CLBP on a group-based exercise plus education program supported by text messages-PAT-Back.

Methods: This descriptive qualitative study was embedded in a feasibility randomized controlled trial (RCT) with older adults aged ≥ 60 with CLBP who participated PAT-Back. PAT-Back consisted of pain education, group and home-based exercises, with the latter being supported by text messages. After the feasibility RCT finished, we conducted 14 (13 women, 1 man) semi-structured interviews with participants. Interview questions were designed to elicit participants' reflections on the program, including its impact on symptoms and factors that facilitated and hindered participation. Transcripts were thematically analyzed.

Results: We identified four themes related to participants' perspectives on PAT-Back: 1) It takes more than intrinsic motivation: Participation in the PAT-Back program was linked to family and peer social support, clinician's supervision, caring clinicians and inaccessibility to treatments; 2) PAT-Back exceeded expectations: Before the intervention older adults did not expect or believed exercise would reduce pain, but this changed as they experienced improvements while engaging in the program; 3) Coexisting comorbidities, challenges with mobility and transport got in the way: at times, having pain in other body sites and not having access to transport and/or safe environments hindered exercise participation; 4) Technology can be both helpful and challenging: motivational text messages were perceived as beneficial by some, but others highlighted challenges related to access and technology literacy.

Conclusions: Older adults' experiences in exercise and education programs for CLBP may be enhanced by social support (from clinicians, peers, family members), access to healthcare and embodied experiences of improvement. Such experiences can also be hindered by comorbidities and broader factors, such as safety to exercise outdoors. Exercise and education interventions for this population should be tailored at the conception phase to meet their needs, especially regarding social support and environmental infrastructure to promote participation and improve symptoms.

Objective: This scoping review maps chiropractic-specific clinical outcomes registries.

Introduction: Clinical outcomes registries track patient outcomes to improve evidence-based practice and quality of care; however, their role in chiropractic remains unclear.

Methods: This research adhered to Joanna Briggs Institute's scoping review outline and methodology, as well as the PRISMA-ScR guidelines. Five databases were searched on January 9, 2025, with subsequent search of grey literature and citation tracking. Sources were included if they described chiropractic-specific registries that reported clinical outcomes data. Two reviewers independently screened 604 citations, extracting data into Excel. Variables included registry characteristics and clinical outcomes collected.

Results: Only one dedicated chiropractic clinical outcomes registry was identified: Spine IQ, launched in 2016 in the US with approximately 50 chiropractors submitting data on over 2000 low back pain patients. Spine IQ collected patient-reported outcome measures including the Oswestry Disability Index, Bournemouth Questionnaire, and the PROMIS physical function measure. By 2018, Spine IQ had completed its pilot phase and planned expansion to 100 clinics. Three sources were excluded: one spine registry not collecting chiropractic outcomes and two databases that included chiropractic data in publications but did not qualify as registries.

Conclusions: This review identified only Spine IQ as a dedicated chiropractic clinical outcomes registry, revealing a significant gap in registry infrastructure within the profession globally. The profession should explore the development of registries to enhance care quality, societal impact, and opportunities for collaborative research.

Background: Contextual factors influence clinicians' delivery of force-based manipulation (FBM), like spinal manipulative therapy (SMT). It is particularly important to discern how contextual factors interact with therapeutic forces delivered to an older adult population, to minimize risk and identify ideal dosage. This study aimed to determine whether contextual factors pertaining to aging result in the modulation of kinetic and kinematic parameters used by experienced clinicians when delivering SMT.

Methods: Participants were randomly presented with a series of 12 AI-generated patient vignettes, featuring both visual and auditory content and representing varying age-related contextual factors. Factors included chronological (35-, 65- and 85-year-old), pathological ("healthy" vs degenerative spine), and felt (perceived as "young" vs. "old") age. Participants delivered SMT to a human analogue manikin based on each vignette, presented six times in randomized order. Kinetic and kinematic parameters were collected and analyzed for differences between "young" and "old" contextual factors of age, using a 3-way repeated measures ANOVA model.

Results: Sixteen licensed chiropractors (8 female, 8 male) participated, with an average age of 45.4 (SD = 9.7, range 34-64) years and 18.3 (SD = 10.8, range 5-39) years of experience. A main effect in peak force was found for both chronological (F(_2,30) = 26.18; p <.001, η_p² = 0.636) and pathological age (F(_1,15) = 11.58; p =.004, η_p² = 0.436), following a stepwise progression of decreased force with increased age and with pathology. No statistically significant differences were found in peak force based on felt age, or in time to peak force for any factor. A main effect was found for chronological age with peak acceleration (F(_2,20) = 9.50; p <.001, η_p² = 0.487) and peak velocity (F(_2,20) = 7.20; p =.004, η_p² = 0.419), but not for pathological or felt age. There was a significant difference in time to peak velocity for felt age (F(_1,10) = 12.23; p =.006, η_p² = 0.550), with a shorter time to peak velocity in response to vignettes with older felt age.

Conclusion: Contextual factors of aging modulated certain kinetic and kinematic characteristics when delivering SMT. This provides evidence that practitioners differentially discern aspects of aging to inform how they deliver FBM dosage. Future research is needed to identify ideal kinetic and kinematic characteristics based on considerations of aging.
