This review evaluates the cost-effectiveness trade-offs between pharmacological and non-pharmacological therapies for non-specific LBP, drawing on recent, high-quality evidence from a comprehensive PubMed search. Evaluated approaches included physical therapy, pharmacological management, cognitive behavioral therapy (CBT), chiropractic manipulation, acupuncture, yoga, and massage therapy. Non-steroidal anti-inflammatory drugs (NSAIDs) remain widely prescribed, yet their safety concerns contrast with the more sustainable benefits of physical therapy and spinal manipulation, with specialized physical therapy yielding 74% greater improvement than conventional therapy combined with NSAIDs. Nevertheless, physical therapy faces limitations related to practitioner variability, accessibility in rural or low-resource settings, upfront costs, and patient adherence. CBT demonstrates significant psychosocial benefits but is constrained by limited availability of qualified practitioners, high costs, and the active participation required from patients. Complementary approaches such as acupuncture and yoga show moderate efficacy and potential economic benefits; however, evidence consistency, delivery infrastructure, and adherence remain challenges, with yoga in particular showing high dropout rates in low-resource contexts. Importantly, acupuncture and yoga may still provide valuable benefits as part of a multimodal strategy. However, the available evidence is heavily concentrated in high-income countries, while studies from low- and middle-income countries remain scarce and unevenly distributed. Only a few LMICs have reported findings, with particularly limited data from Southeast Asia, underscoring critical research gaps in these regions. No single therapy emerges as universally superior for non-specific LBP, as effectiveness depends on patient profile, healthcare context, and cost. These findings highlight the importance of integrated, scalable, and accessible multidisciplinary models aligned with the biopsychosocial framework to optimize long-term outcomes.Keywords: low back pain, conservative treatment, complementary medicine, cost effectiveness, pharmacological therapy

IntroductionTelework has become increasingly prominent as a flexible work arrangement, particularly since the COVID-19 pandemic. For workers managing health conditions, it may support continued employment by influencing key work-related phenomena such as absenteeism, presenteeism and return to work (RTW) process. However, current evidence on the impact of telework on the work-related outcome to manage health condition in the workplace remains limited and fragmented.ObjectiveThis scoping review aimed to map the existing literature on the impact of telework on absenteeism, presenteeism, and RTW outcomes among adult workers with health conditions.MethodsIncluded studies were either qualitative, quantitative, or mixed methods, published in English or French, including adults with any physical or psychological health conditions. At least one outcome domain (absenteeism, presenteeism, or RTW) was required. Eight databases were searched from inception to May 2025: Medline, CINAHL, APA PsycINFO, Academic Search Complete, Business Source Complete, Scopus, Sociological Abstracts, and ABI/INFORM Global. Data extraction focused on study design, objectives, variables/definitions, sample size, health status, demographic characteristics, individual characteristics, organizational factors and results. Data were synthesized by the outcome domain (absenteeism, presenteeism, RTW) and stratified by study type (quantitative vs. qualitative).ResultsFrom 4,093 records, 21 studies were included. The majority of studies suggest that telework contributes to reduced absenteeism by increasing work flexibility. Telework is also consistently associated with facilitating RTW, particularly following surgery or in the context of chronic illness, by supporting work reintegration and shortening the duration of sick leave. In contrast, findings on presenteeism are conflicting: some studies report that telework increases the likelihood of working while sick, others suggest a decrease, and some report no significant impact or conflicting results. These outcomes appear to be influenced by contextual factors, including health status, demographic variables, individual characteristics, and organizational context.ConclusionTelework appears to offer flexibility that can reduce absenteeism and facilitate RTW. However, its impact on presenteeism is less consistent and may even encourage working while sick if not properly supervised. Future studies should examine which policies most effectively maximize the benefits of telework while minimizing potential drawbacks.

<h4>Objective</h4>To model future use of chiropractic services and predict clinical resource needs within the Veterans Health Administration (VA) over the next 5 years.<h4>Methods</h4>A serial cross-sectional analysis of chiropractic use data from VA's Corporate Data Warehouse for fiscal years (FY) 2017 through 2022 (10/1/2016-9/30/2022). We calculated the proportion of VA chiropractic users-via care provided on-station and/or purchased from Community Care Network (CCN) providers-compared to overall VA healthcare users for each FY. We calculated the historical year-over-year compound annual growth rate (CAGR), which was used to predict use in FY2023 through 2027 (10/1/2022-9/30/2027).<h4>Results</h4>VA's chiropractic use rate increased from 1.4% in FY2017 to 3.5% in FY2022, at which point 2.0% of VA users received only CCN chiropractic care, 1.3% only on-station, and 0.2% both. During the 6-year observation period, the CAGRs were overall 17.9%, CCN only 23.8%, on-station only 12.4%, and both 27.7%. Using those rates to extrapolate, by the end of FY2027 overall use will be 8.9%, with 5.9% only CCN, 2.3% only on-station, and 0.6% both.<h4>Conclusion</h4>Overall use of VA chiropractic services is projected to more than double from FY 2022 to FY2027. These findings underscore the need for proactive resource planning to address the expected increased use of both CCN and on-station care.

Abstract Background Research enables a profession to establish its cultural authority, validate its professional roles and ensure ongoing improvement in the quality of its academic programming. Despite the clear importance of research, a mature research culture has eluded the chiropractic profession. A fostering institutional culture that enables, values, and supports research activity is essential to building research capacity. Our study aimed to collect information about the existing research capacity and culture at the Canadian Memorial Chiropractic College (CMCC) and explore the views, attitudes and experiences of faculty members regarding research. Methods We conducted a sequential explanatory mixed methods study with quantitative priority between April and July, 2023. Quantitative data were collected using the Research Capacity and Culture (RCC) tool. Survey results guided the qualitative data collected from four faculty focus groups with varying levels of research experience. Quantitative data were analyzed using descriptive statistics by domain and stratified by research education and workload. The qualitative data were thematically analyzed and then integrated with the quantitative results to provide deeper meaning to the results. Results The faculty survey response rate was 42% (59/144). Attributes at the organization or department level were consistently rated as either moderate or high; however, research skills at an individual level were more variable and influenced by factors such as research workload and highest research-related academic qualification. Qualitative focus group data were categorized under four themes: institutional factors, resource allocation, career pathways and personal factors. Lower scores for survey items related to mentorship, research planning and ensuring faculty research career pathways, as well as the identified workload and time-related barriers (e.g., other work roles and desire for work/life balance) for engaging in research were supported by each of the four themes. Research motivators included keeping the brain stimulated, developing skills and increasing job satisfaction. Conclusion The quantitative and qualitative information in this study provides a baseline evaluation for RCC and identifies key factors impacting RCC at the CMCC. This information is critical for planning, developing, implementing, and evaluating future interventions to enhance research capacity. Ultimately, these efforts are aimed at maturing the research culture of the chiropractic profession.

The brain cortex is the structure that is typically injured in traumatic brain injury (TBI) and is anatomically connected with other brain regions, including the striatum and hypothalamus, which are associated in part with motor function and the regulation of body temperature, respectively. We investigated whether a TBI extending to the striatum could affect peripheral and core temperatures as an indicator of autonomic thermoregulatory function. Moreover, it is unknown whether thermal modulation is accompanied by hypothalamic and cortical monoamine changes in rats with motor function recovery. The animals were allocated into three groups: the sham group (sham), a TBI group with a cortical contusion alone (TBI alone), and a TBI group with an injury extending to the dorsal striatum (TBI + striatal injury). Body temperature and motor deficits were evaluated for 20 days post-injury. On the 3rd and 20th days, rats were euthanized to measure the serotonin (5-HT), noradrenaline (NA), and dopamine (DA) levels using high-performance liquid chromatography (HPLC). We observed that TBI with an injury extending to the dorsal striatum increased core and peripheral temperatures. These changes were accompanied by a sustained motor deficit lasting for 14 days. Furthermore, there were notable increases in NA and 5-HT levels in the brain cortex and hypothalamus both 3 and 20 days after injury. In contrast, rats with TBI alone showed no changes in peripheral temperatures and achieved motor function recovery by the 7th day post-injury. In conclusion, our results suggest that TBI with an injury extending to the dorsal striatum elevates both core and peripheral temperatures, causing a delay in functional recovery and increasing hypothalamic monoamine levels. The aftereffects can be attributed to the injury site and changes to the autonomic thermoregulatory functions.

Introduction: The management of musculoskeletal disorders is complex and requires a multidisciplinary approach. Manual therapies, such as spinal manipulative therapy (SMT), are often recommended as an adjunct treatment and appear to have demonstrable effects on pain and short-term disability in several spinal conditions. However, no definitive mechanism that can explain these effects has been identified. Identifying relevant prognostic factors is therefore recommended for people with back pain.Objective: The main purpose of this study was to identify short-term candidate prognostic factors for clinically significant responses in pain, disability and global perceived change (GPC) following a spinal manipulation treatment in patients with non-specific thoracic back pain.Methods: Patients seeking care for thoracic spine pain were invited to participate in the study. Pain levels were recorded at baseline, post-intervention, and 1 week after a single session of SMT. Disability levels were collected at baseline and at 1-week follow-up. GPC was collected post-intervention and at 1-week follow-up. Biomechanical parameters of SMT, expectations for improvement in pain and disability, kinesiophobia, anxiety levels as well as perceived comfort of spinal manipulative therapy were assessed.Analysis: Differences in baseline characteristics were compared between patients categorized as responders or non-responders based on their pain level, disability level, and GPC at each measurement time point. Binary logistic regression was calculated if the statistical significance level of group comparisons (responder vs. non-responders) was equal to, or &lt;0.2 for candidate prognostic factors.Results: 107 patients (62 females and 45 males) were recruited. Mean peak force averaged 450.8 N with a mean thrust duration of 134.9 ms. Post-intervention, comfort was associated with pain responder status (p &lt; 0.05) and GPC responder status (p &lt; 0.05), while expectation of disability improvement was associated with GPC responder status (p &lt; 0.05). At follow-up, comfort and expectation of pain improvement were associated with responder GPC status (p &lt; 0.05). No association was found between responder pain, disability or GPC status and biomechanical parameters of SMT at any time point.Discussion: No specific dosage of SMT was associated with short-term clinical responses to treatment. However, expectations of improvement and patient comfort during SMT were associated with a positive response to treatment.

Abstract Background Benefits from low back pain (LBP) treatments seem to be related to patients changing their pain cognitions and developing an increased sense of control. Still, little is known about how these changes occur. The objective of this study was to gain insights into possible shifts in the understanding of LBP and the sense of being able to manage pain among patients participating in a LBP self-management intervention. Methods Using a qualitative study and a content analytic framework, we investigated the experiences of patients with LBP who participated in ‘GLA:D® Back’, a group-based structured patient education and exercise program. Data were generated through qualitative semi-structured interviews conducted between January 2019 and October 2019. Interviews focused on experiences with pain and were analysed using a thematic analytical approach. The Common Sense Model and self-efficacy theory formed the theoretical framework for the interpretations. Participants were sampled to represent people who were either dissatisfied or satisfied with their participation in GLA:D® Back. Fifteen participants aged 26–62, eight women and seven men, were interviewed from February to April 2020. Results Four main themes, corresponding to the characterisation of four patient groups, were identified: ‘Feeling miscast, ‘Maintaining reservations', ‘Struggling with habits’ and ‘Handling it’. The participants within each group differed in how they understood, managed, and communicated about their LBP. Some retained the perception of LBP as a threatening disease, some expressed a changed understanding that did not translate into new behaviors, while others had changed their understanding of pain and their reaction to pain. Conclusions The same intervention was experienced very differently by different people dependent on how messages and communication resonated with the individual patient's experiences and prior understanding of LBP. Awareness of the ways that individuals’ understanding of LBP interact with behaviour and physical activities appear central for providing adaptive professional support and meeting the needs of individual patients.

BackgroundThe COVID-19 pandemic has greatly limited patients' access to care for spine-related symptoms and disorders. However, physical distancing between clinicians and patients with spine-related symptoms is not solely limited to restrictions imposed by pandemic-related lockdowns. In most low- and middle-income countries, as well as many underserved marginalized communities in high-income countries, there is little to no access to clinicians trained in evidence-based care for people experiencing spinal pain. ObjectiveThe aim of this study is to describe the development and present the components of evidence-based patient and clinician guides for the management of spinal disorders where in-person care is not available. MethodsUltimately, two sets of guides were developed (one for patients and one for clinicians) by extracting information from the published Global Spine Care Initiative (GSCI) papers. An international, interprofessional team of 29 participants from 10 countries on 4 continents participated. The team included practitioners in family medicine, neurology, physiatry, rheumatology, psychology, chiropractic, physical therapy, and yoga, as well as epidemiologists, research methodologists, and laypeople. The participants were invited to review, edit, and comment on the guides in an open iterative consensus process. ResultsThe Patient Guide is a simple 2-step process. The first step describes the nature of the symptoms or concerns. The second step provides information that a patient can use when considering self-care, determining whether to contact a clinician, or considering seeking emergency care. The Clinician Guide is a 5-step process: (1) Obtain and document patient demographics, location of primary clinical symptoms, and psychosocial information. (2) Review the symptoms noted in the patient guide. (3) Determine the GSCI classification of the patient’s spine-related complaints. (4) Ask additional questions to determine the GSCI subclassification of the symptom pattern. (5) Consider appropriate treatment interventions. ConclusionsThe Patient and Clinician Guides are designed to be sufficiently clear to be useful to all patients and clinicians, irrespective of their location, education, professional qualifications, and experience. However, they are comprehensive enough to provide guidance on the management of all spine-related symptoms or disorders, including triage for serious and specific diseases. They are consistent with widely accepted evidence-based clinical practice guidelines. They also allow for adequate documentation and medical record keeping. These guides should be of value during periods of government-mandated physical or social distancing due to infectious diseases, such as during the COVID-19 pandemic. They should also be of value in underserved communities in high-, middle-, and low-income countries where there is a dearth of accessible trained spine care clinicians. These guides have the potential to reduce the overutilization of unnecessary and expensive interventions while empowering patients to self-manage uncomplicated spinal pain with the assistance of their clinician, either through direct in-person consultation or via telehealth communication.

Adaptations of the lower back to bipedalism are frequently discussed but infrequently demonstrated in early fossil hominins. Newly discovered lumbar vertebrae contribute to a near-complete lower back of Malapa Hominin 2 (MH2), offering additional insights into posture and locomotion in Australopithecus sediba. We show that MH2 possessed a lower back consistent with lumbar lordosis and other adaptations to bipedalism, including an increase in the width of intervertebral articular facets from the upper to lower lumbar column (‘pyramidal configuration’). These results contrast with some recent work on lordosis in fossil hominins, where MH2 was argued to demonstrate no appreciable lordosis (‘hypolordosis’) similar to Neandertals. Our three-dimensional geometric morphometric (3D GM) analyses show that MH2’s nearly complete middle lumbar vertebra is human-like in overall shape but its vertebral body is somewhat intermediate in shape between modern humans and great apes. Additionally, it bears long, cranially and ventrally oriented costal (transverse) processes, implying powerful trunk musculature. We interpret this combination of features to indicate that A. sediba used its lower back in both bipedal and arboreal positional behaviors, as previously suggested based on multiple lines of evidence from other parts of the skeleton and reconstructed paleobiology of A. sediba.

Abstract Background Previous studies of patients with neck pain have reported a high variability in prevalence of MRI findings of disc degeneration, disc herniation etc. This is most likely due to small and heterogenous study populations. Reasons for only including small study samples could be the high cost and time-consuming procedures of having radiologists coding the MRIs. Other methods for extracting reliable imaging data should therefore be explored. The objectives of this study were 1) to examine inter-rater reliability among a group of chiropractic master students in extracting information about cervical MRI-findings from radiologists´ narrative reports, and 2) to describe the prevalence of MRI findings in the cervical spine among different age groups in patients above age 18 with neck pain. Method Adult patients with neck pain (with or without arm pain) seen in a public hospital department between 2011 and 2014 who had an MRI of the cervical spine were identified in the patient registry ‘SpineData’. MRI-findings were extracted and quantified from radiologists’ narrative reports by second-year chiropractic master students based on a set of coding rules for the process. The inter-rater reliability was quantified with Kappa statistics and the prevalence of the MRI findings were calculated. Results In total, narrative MRI reports from 611 patients were included. The patients had a mean age of 52 years (SD 13; range 19–87) and 63% were women. The inter-observer agreement in coding MRI findings ranged from substantial (κ = 0.78, CI: 0.33–1.00) to almost perfect (κ = 0.98, CI: 0.95–1.00). The most prevalent MRI findings were foraminal stenosis (77%), uncovertebral arthrosis (74%) and disc degeneration (67%) while the least prevalent findings were nerve root compromise (2%) and Modic changes type 2 (6%). Modic type 1 was mentioned in 25% of the radiologists’ reports. The prevalence of all findings increased with age, except disc herniation which was most prevalent for patients in their forties. Conclusion MRI-findings from radiologists’ narrative reports can reliably be extracted by chiropractic master students with a minimum of training. Degenerative findings in the cervical spine were most commonly found at levels C5/C6 and C6/C7 and increased with age.

Abstract Background The quality of health care provider clinical decisions has long been recognized as variable. Research has focused on clinical decision making with the aim of improving patient outcomes. No studies have looked at chiropractic students´ abilities in this regard. Method In 2016, advanced students from two Australian chiropractic programs (N = 444) answered a questionnaire on patient case scenarios for neck and low back pain (LBP). We selected 7 scenarios representing the three categories; continuing care, non-indicated care, and contraindicated care. This represented a total of 21 tested scores. Comparisons of correct answers were made a) for program years 3, 4 and 5, and b) between the three categories of care. Results In almost 1/3 of scenarios, correct scores were 70% or greater. Best results were for two neck pain cases (simple and with spinal cord involvement). Continued care showed most improvements with study year. However, the scenarios that reflected non-indication for continued care had much worse results and did not improve in higher years. For the obvious contraindicated neck scenario, the results were good from the beginning and progressively improved and for a contraindicated LBP scenario the results started poorly in year 3 but improved over the program years. Conclusions Although student responses were generally good, there is still room for improvement, especially for non-indicated care. The quality of students’ clinical decisions can be measured and thus has the potential to be used by chiropractic educators and regulatory bodies to identify student’s in need of assistance as well as to monitor chiropractic programs in relation to student competence. Trial registration Not applicable.

Abstract Background Similar types of trajectory patterns have been identified by Latent Class Analyses (LCA) across multiple low back pain (LBP) cohorts, but these patterns are impractical to apply to new cohorts or individual patients. It would be useful to be able to identify trajectory subgroups from descriptive definitions, as a way to apply the same definitions of mutually exclusive subgroups across populations. In this study, we investigated if the course trajectories of two LBP cohorts fitted with previously suggested trajectory subgroup definitions, how distinctly different these subgroups were, and if the subgroup definitions matched with LCA-derived patterns. Methods Weekly measures of LBP intensity and frequency during 1 year were available from two clinical cohorts. We applied definitions of 16 possible trajectory subgroups to these observations and calculated the prevalence of the subgroups. The probability of belonging to each of eight LCA-derived patterns was determined within each subgroup. LBP intensity and frequency were described within subgroups and the subgroups of ‘fluctuating’ and ‘episodic’ LBP were compared on clinical characteristics. Results All of 1077 observed trajectories fitted with the defined subgroups. ‘Severe episodic LBP’ was the most frequent pattern in both cohorts and ‘ongoing LBP’ was almost non-existing. There was a clear relationship between the defined trajectory subgroups and LCA-derived trajectory patterns, as in most subgroups, all patients had high probabilities of belonging to only one or two of the LCA patterns. The characteristics of the six defined subgroups with minor LBP were very similar. ‘Fluctuating LBP’ subgroups were significantly more distressed, had more intense leg pain, higher levels of activity limitation, and more negative expectations about future LBP than ‘episodic LBP’ subgroups. Conclusion Previously suggested definitions of LBP trajectory subgroups could be readily applied to patients’ observed data resulting in subgroups that matched well with LCA-derived trajectory patterns. We suggest that the number of trajectory subgroups can be reduced by merging some subgroups with minor LBP. Stable levels of LBP were almost not observed and we suggest that minor fluctuations in pain intensity might be conceptualised as ‘ongoing LBP’. Lastly, we found clear support for distinguishing between fluctuating and episodic LBP.

Abstract. Introduction:. Pain-related fear plays a substantial role in chronic low back pain (LBP) by amplifying the experienced disability. Related dysfunctional emotions and cognitions may also affect sensory aspects of pain through a modulatory pathway in which the periaqueductal gray (PAG) and the amygdala play key roles. Objectives:. We therefore hypothesized a differential amygdala-PAG functional connectivity (FC) in patients with chronic LBP that is modulated by the degree of pain-related fear. Methods:. We used data of a previously reported fMRI study where 20 chronic LBP patients (7 females, mean age = 39.35) and 20 healthy controls (12 females, mean age = 32.10) were asked to observe video clips showing potentially harmful and neutral activities for the back. Pain-related fear was assessed using the Tampa Scale of kinesiophobia (TSK) and Fear Avoidance Beliefs questionnaires (FABQ). Generalized psychophysiological interactions were used to reveal task-based FC. Results:. Compared to controls, patients exhibited a significant decrease in amygdala-PAG-FC (P = 0.022) during observation of harmful activities, but not of neutral activities. Furthermore, amygdala-PAG-FC correlated negatively with Tampa Scale of kinesiophobia scores in patients (R2 = 0.28, P = 0.01) but not with Fear Avoidance Beliefs questionnaires scores. Discussion:. Our findings might indicate a maladaptive psychobiological interaction in chronic LBP patients characterized by a disrupted amygdala-PAG-FC that is modulated by the degree of pain-related fear. These results shed new light on brain mechanisms underlying psychological factors that may have pronociceptive effects in chronic LBP.

<h4>Background</h4>The use of complementary and alternative medicine (CAM) is growing. However the factors contributing to changes over time and to birth cohort differences in CAM use are not well understood.<h4>Setting</h4>We used data from 10186 participants, who were aged 20-69 years at the first cycle of data collection in the longitudinal component of the Canadian National Population Health Survey (1994/95-2010/11). We examined chiropractic and other practitioner-based CAM use with a focus on five birth cohorts: pre-World War II (born 1925-1934); World War II (born 1935-1944); older baby boomers (born 1945-1954); younger baby boomers (born 1955-1964); and Gen Xers (born 1965-1974). The survey collected data every two years on predisposing (e.g., sex, education), enabling (e.g., income), behavior-related factors (e.g., obesity), need (e.g., chronic conditions), and use of conventional care (primary care and specialists).<h4>Results</h4>The findings suggest that, at corresponding ages, more recent cohorts reported greater CAM (OR = 25.9, 95% CI: 20.0; 33.6 for Gen Xers vs. pre-World War) and chiropractic use than their predecessors (OR = 2.2, 95% CI: 1.7; 2.8 for Gen Xers vs. pre-World War). There was also a secular trend of increasing CAM use, but not chiropractic use, over time (period effect) across all ages. Factors associated with cohort differences were different for CAM and chiropractic use. Cohort differences in CAM use were partially related to a period effect of increasing CAM use over time across all ages while cohort differences in chiropractic use were related to the higher prevalence of chronic conditions among recent cohorts. The use of conventional care was positively related to greater CAM use (OR = 1.8, 95% CI: 1.6; 2.0) and chiropractic use (OR = 1.2, 95% CI: 1.1; 1.4) but did not contribute to changes over time or to cohort differences in CAM and chiropractic use.<h4>Conclusion</h4>The higher CAM use over time and in recent cohorts could reflect how recent generations are approaching their healthcare needs by expanding conventional care to include CAM therapies and practice for treatment and health promotion. The findings also underscore the importance of doctors discussing CAM use with their patients.

Abstract Background Low back pain (LBP) patients with related leg pain and signs of nerve root involvement are considered to have a worse prognosis than patients with LBP alone. However, it is unclear whether leg pain location above or below the knee and the presence of neurological signs are important in primary care patients. The objectives of this study were to explore whether the four Quebec Task Force categories (QTFC) based on the location of pain and on neurological signs have different characteristics at the time of care seeking, whether these QTFC are associated with outcome, and if so whether there is an obvious ranking of the four QTFC on the severity of outcomes. Method Adult patients seeking care for LBP in chiropractic or general practice were classified into the four QTFC based on self-reported information and clinical findings. Analyses were performed to test the associations between the QTFC and baseline characteristics as well as the outcomes global perceived effect and activity limitation after 2 weeks, 3 months, and 1 year and also 1-year trajectories of LBP intensity. Results The study comprised 1271 patients; 947 from chiropractic practice and 324 from general practice. The QTFC at presentation were statistically significantly associated with most of the baseline characteristics, with activity limitation at all follow-up time points, with global perceived effect at 2 weeks but not 3 months and 1 year, and with trajectories of LBP. Severity of outcomes in the QTFC increased from LBP alone, across LBP with leg pain above the knee and below the knee to LBP with nerve root involvement. However, the variation within the categories was considerable. Conclusion The QTFC identify different LBP subgroups at baseline and there is a consistent ranking of the four categories with respect to outcomes. The differences between outcomes appear to be large enough for the QTFC to be useful for clinicians in the communication with patients. However, due to variation of outcomes within each category individuals’ outcome cannot be precisely predicted from the QTFC alone. It warrants further investigation to find out if the QTFC can improve existing prediction tools and guide treatment decisions.
