RESUMO
PURPOSE: Eldercare work is characterised by high quantitative work demands and high occurrence of musculoskeletal pain and sickness absence. Our aim was to investigate the association between quantitative demands aggregated at the different organizational levels of eldercare and low back pain (LBP) and sickness absence due to pain among workers. METHODS: This study was conducted in 527 eldercare workers from 105 wards across 20 nursing homes in Denmark. We collected workers' perceived quantitative demands at baseline and workers' LBP and sickness absence repeatedly over the following year. We aggregated worker-level quantitative demands to the ward and nursing home-levels, and used mixed-effects regression models to investigate the associations between quantitative demands at different organizational levels and LBP and sickness absence over 1 year. RESULTS: Across all models, increased quantitative demands (0-100 scale) at the worker-level was associated with an increased likelihood (OR 1.02) and intensity of LBP (ß = 0.01). We did not identify any associations between quantitative demands at the ward-level and either of our outcomes. Across all models, increased quantitative demands at the nursing home-level was associated with increased days with sickness absence due to pain (ß = 0.03 to 0.06). CONCLUSION: In eldercare, workers' perceived quantitative demands are associated with the presence and intensity of LBP. Further, quantitative demands across the overall nursing home-level are associated with sickness absence due to pain among eldercare workers. These results are of relevance to developing organisational interventions targeting quantitative demands to reduce sickness absence in eldercare.

BACKGROUND: Pooling data from thigh-worn accelerometers across multiple studies has great potential to advance evidence on the health benefits of physical activity. This requires harmonization of information on body postures, physical activity types, volumes and time patterns across different brands of devices. The aim of this study is to compare the physical behavior estimates provided by three different brands of thigh-worn accelerometers. METHODS: Twenty participants volunteered for a 7-day free-living measurement. Three accelerometers - ActiGraph GT3X+, Axivity AX3 and ActivPAL Micro4 - were randomly placed in a vertical line on the midsection of the right thigh. Raw data from each accelerometer was processed and classified into 8 physical activities and postures using the Acti4 software. Absolute differences between estimates and the respective coefficient of variation (CV) were calculated. RESULTS: We observed very minor differences between physical behavior estimates from three different accelerometer brands. When averaged over 24 h (1,440 min), the absolute difference (CV) between accelerometers were: 1.2 mins (0.001) for lying/sitting, 3.4 mins (0.02) for standing, 3.5 mins (0.06) for moving, 1.9 mins (0.03) for walking, 0.1 mins (0.19) for running, 1.2 mins (0.19) for stair climbing, 1.9 mins (0.07) for cycling. Moreover, there was an average absolute difference of 282 steps (0.03) per 24 h. CONCLUSIONS: Physical behaviors were classified with negligible difference between the accelerometer brands. These results support harmonization of data from different thigh-worn accelerometers across multiple cohorts when analyzed in an identical manner.

PURPOSE: A multifaceted workplace intervention consisting of participatory ergonomics, physical training, and cognitive-behavioural training (CBT) has shown effectiveness for reducing low back pain (LBP). However, the mechanisms of action underlying these intervention components are not well understood. METHODS: This was a mediation analysis of a cluster-randomised controlled trial of a multifaceted intervention in 420 workers in elderly care. Mediation analysis was carried out via structural equation modelling. Potential mediators investigated were: fear-avoidance beliefs, perceived muscle strength, use of assistive devices at work and perceived physical exertion at work. LBP outcomes assessed were: days with LBP, LBP intensity and days with bothersome LBP. RESULTS: There were no significant indirect effects of the intervention on LBP outcomes. There were significant effects of the intervention on both fear-avoidance measures [ß = - 0.63, 95% CI (1.23, 0.03); ß = - 1.03, 95% CI (- 1.70, - 0.34)] and the use of assistive devices [ß = - 0.55, 95% CI (- 1.04, - 0.05)], but not on perceived muscle strength [ß = - 0.18, 95% CI (- 0.50, 0.13)] or physical exertion [ß = - 0.05, 95% CI (- 0.40, 0.31)]. The only potential mediator with a significant effect on LBP outcomes was physical exertion, which had a significant effect on LBP intensity [ß = 0.14, 95% CI (0.04, 0.23)]. CONCLUSIONS: A multifaceted intervention consisting of participatory ergonomics, physical training, and CBT was able to decrease fear-avoidance beliefs and increase use of assistive devices in the workplace. However, these changes did not explain the effect of any of the intervention components on days with LBP, LBP intensity and days with bothersome LBP.

INTRODUCTION: Perceived quantitative demands at work have been associated with poor mental and physical health, long-term sickness absence and subsequent early retirement. Identifying modifiable determinants of perceived quantitative demands at different levels of the organization is key to developing effective interventions. The aim of the study was to identify determinants of perceived quantitative demands at work and examine the extent to which they occur at different levels of the eldercare organisation (i.e. the worker, ward and nursing home levels). METHODS: We collected data on 383 eldercare workers in 95 wards at 20 nursing homes in Denmark using workplace observations and questionnaires to workers and their managers. Perceived quantitative work demands were assessed using two items from the Copenhagen Psychosocial Questionnaire, II. We identified contributions to overall variability from the three organisational levels using variance components analysis, and examined associations between determinants at these three levels and quantitative demands. RESULTS: Almost all (90.9%) the variability in perceived quantitative demands occurred between eldercare workers (within wards). Determinants significantly associated with lower quantitative demands were: having a job as a care helper, working fixed evening shifts, being born outside Denmark, having lower influence at work, higher quality of leadership and lower emotional demands. None of the investigated physical factors (e.g. resident handlings, push/pull tasks, step-count) were associated with perceived quantitative demands. CONCLUSION: We found that the variability in perceived quantitative demands occurred primarily between eldercare workers within wards. Our study indicates that psychosocial work environment factors are the strongest modifiable determinants of perceived quantitative demands in eldercare, while organisational factors related to job position, shift, and resident-staff ratio also play a role. Interventions should test if changes in these determinants can reduce perceived quantitative demands at work in eldercare.

The purpose of our study was to investigate which organizational levels and factors determine the number of resident handlings in eldercare. We conducted a multi-level study, stratified on day and evening shifts, including information on four levels: nursing homes (n = 20), wards within nursing homes (day, n = 120; evening, n = 107), eldercare workers within wards (day, n = 619; evening, n = 382), and within eldercare workers (i.e., days within eldercare workers; day, n = 5572; evening, n = 2373). We evaluated the influence of each level on the number of resident handlings using variance components analysis and multivariate generalized linear mixed models. All four levels contributed to the total variance in resident handlings during day and evening shifts, with 13%/20% at "nursing homes", 21%/33% at "wards within nursing homes", 25%/31% at "elder-care workers within wards", and 41%/16% "within eldercare workers", respectively. The percentage of residents with a higher need for physical assistance, number of residents per shift, occupational position (only within day shifts), and working hours per week (only within day shifts) were significantly associated with the number of resident handlings performed per shift. Interventions aiming to modify number of resident handlings in eldercare ought to target all levels of the eldercare organization.

OBJECTIVES: Current knowledge on the determinants of step-rate at different organizational levels is limited. Thus, our aim was to identify, in eldercare, at what workplace level differences in step-rate occur and to identify determinants of workers' step-rate at these levels. METHODS: Participants were 420 eldercare workers from 17 nursing homes (126 wards) in Denmark. Accelerometry was used to assess step-rate (steps per hour) of workers over multiple shifts. We assessed various determinants at different levels of the workplace, i.e. at the (i) shift, (ii) worker, (iii) ward, and (iv) nursing home levels. Variance components analysis identified the percentage contribution to total variance in step-rate from each respective level. Multi-level linear regression modelling was used to investigate the association between candidate determinants at each level and step-rate. RESULTS: Differences in eldercare workers' step-rate occurred primarily between shifts (within workers; 44.9%) and between workers (within wards; 49.1%). A higher step-rate was associated with: (i) weekend and evening shifts (versus weekday/day); (ii) job as a care helper (versus care aide) and an increased proportion of time spent on direct care tasks; (iii) working in a somatic ward (versus dementia), an increased resident-staff ratio and permission to take unscheduled breaks; and (iv) lack of elevators. CONCLUSIONS: We found that nearly all variability in step-rate in eldercare work occurs between shifts (within workers) and between workers (within wards). The main determinants of step-rate were related to the type of shift, type of work tasks, staffing ratio, break policy, and availability of elevators.

OBJECTIVES: We aimed to identify eldercare wards with different types of resident handling characteristics ('phenotypes') and determine the prospective association between these characteristics and musculoskeletal pain and sickness absence among workers during a one-year follow-up. METHODS: Our study was based on the DOSES cohort, including 467 workers at 103 eldercare wards. At baseline, resident handlings were assessed using onsite observations. Workers' self-reported musculoskeletal pain and sickness absence were assessed during the following year using text messages. Observations of the frequency of handlings per shift, use of assistive devices, assistance from others, and barriers (interruptions and impediments) were estimated for each worker, aggregated at ward level, and entered into a latent profile analysis, identifying ward phenotypes. We then used generalized estimating equations to determine associations between ward phenotypes, musculoskeletal pain and sickness absence. RESULTS: We identified four ward phenotypes: 'turbulent' (many handlings with devices and assistance, many barriers), 'strained' (many handlings without devices or assistance, some barriers), 'unpressured' (few handlings, yet without devices or assistance, few barriers) and 'balanced' (some handlings with devices and assistance, some barriers). Compared to workers in balanced wards, workers in turbulent wards had more days with neck-shoulder and low-back pain (LBP); and those working in strained wards had more days with LBP and higher pain intensities. CONCLUSION: We found that ward phenotypes based on resident handling characteristics were predictive of musculoskeletal pain and sickness absence over one year. This shows that organizational factors related to resident handling are important determinants of musculoskeletal health among eldercare workers.

OBJECTIVE: To assess whether an exercise and education program was more effective than an education booklet for preventing recurrence of low back pain (LBP). DESIGN: Randomized controlled trial. METHODS: Participants aged 18 years or older who had recovered from an episode of LBP within the previous week were recruited from primary care practices and the community. Participants were randomized to receive either 12 weeks of exercise and education (8 supervised exercise sessions and 3 one-on-one sessions) or a control (education booklet). The primary outcome was time to recurrence of LBP during the 1-year follow-up. Times to recurrence of LBP leading to activity limitation, care seeking, and work absence were secondary outcomes. Data were analyzed with Cox regression using intention-to-treat principles. RESULTS: We planned to include 160 participants but included 111 (exercise and education, n = 57; educational booklet, n = 54). At the end of the study period, data completeness was 84.2%. Thirty-six (63%) participants in the exercise and education group and 31 (57%) participants in the control group had a recurrence of LBP. There was no statistically significant difference in time to recurrence of pain between groups (hazard ratio = 1.09; 95% confidence interval: 0.7, 1.8). There was no statistically significant effect for any of the secondary outcomes. CONCLUSION: Among people recently recovered from LBP, exercise and education may not meaningfully reduce risk of recurrence compared to providing an educational booklet.

OBJECTIVES: Previous research has shown strong associations between occupational physical activity (OPA) and need for recovery (NFR). However this research has only utilized self-reported measures of OPA which may be biased. Thus, there is a need for investigating if the previously documented association between self-reported OPA and NFR can be found when using technical measures of OPA. There is also the need to investigate whether older workers are particularly susceptible to increased NFR, since age-related declines in physical capacity mean that it is likely these workers will have a higher NFR for a given physical activity. The aim of this study was to investigate the association between technically measured OPA and NFR, and whether this relationship is modified by age. METHODS: This study utilized data from the Danish Physical Activity Cohort with Objective Measurements cohort-comprising Danish workers (n = 840) from the cleaning, manufacturing, and transportation sectors. OPA was measured by accelerometers attached to the thigh and upper back for at least one work day and classified into four physical behaviour categories (sedentary, standing, light, or moderate/vigorous). NFR was measured using a shortened version of the Danish NFR scale. Analysis was conducted using linear regression and isotemporal substitution analyses for compositional data. RESULTS: The overall association between OPA and NFR was statistically significant in the unadjusted model (P < 0.001), but not when adjusted for age, sex, occupation, and shift work (P = 0.166). Isotemporal substitution showed small but significant reductions in NFR when increasing sedentary time relative to other behaviours (adjusted: ΔNFR = -0.010 [-0.019; -0.001]). There were no significant interactions between age and OPA (P = 0.409). CONCLUSIONS: This study found significant associations between OPA and NFR, but the effect sizes were small. Reallocating 30 min to sedentary behaviours from other behaviours was associated with a reduced NFR, but the effect size may not be practically relevant. Moreover, no clear modifying effects of age were identified.

OBJECTIVES: High perceived physical exertion is common in eldercare workers and a strong predictor for impaired health. However, little is known on how physical behaviors at work associate with physical exertion in this group. The aim of this study was to determine the extent to which the composition of physical behaviors at work is associated with perceived physical exertion in nursing home eldercare workers, and the extent to which these associations are modified by psychosocial resources. METHODS: Our population consisted of 399 female eldercare workers from 126 wards in 20 different nursing homes. We evaluated time spent in physical behaviors at work [sitting, standing still, light activities (LAs), and moderate to vigorous activities (MVAs)] using triaxial accelerometers worn, on average, for three working days. We accounted for inherent codependency between the behaviors using compositional data analysis. We used multilevel linear mixed regression models to determine associations between the behaviors and perceived exertion, measured on a numeric rating scale (0-10), and included interactions between each behavior and psychosocial resources (influence at work, social support, and quality of leadership) to determine a possible moderating effect of resources. Regression results were illustrated using isotemporal substitution. RESULTS: Sitting was negatively (ß: -0.64; P < 0.01) while MVA was positively (ß: 0.95; P = 0.02) associated with perceived exertion. According to isotemporal substitution, replacing 30 min of MVA by sitting would, for an average worker, be associated with a decrease in physical exertion by -0.14 on the 0-10 scale. Job resources marginally moderated the association between LA and exertion. Thus, among workers with low influence and low social support, we found a positive association between LA and exertion, while that was not found for workers with medium or high influence and support (interactions for influence and support: P = 0.08 and P = 0.10). CONCLUSIONS: Our findings suggest that reallocating time from MVA to sitting can mitigate perceived physical exertion in eldercare workers. More time in LA increased physical exertion only for workers with low psychosocial resources, supporting a positive effect of a better psychosocial work environment in elderly care.

INTRODUCTION: The Prospective Physical Activity Sitting and Sleep consortium (ProPASS) is an international collaboration platform committed to harmonise thigh-worn accelerometry data. The aim of this paper is to (1) outline observational thigh-worn accelerometry studies and (2) summarise key strategic directions arising from the inaugural ProPASS meeting. METHODS: (1) We performed a systematic scoping review for observational studies of thigh-worn triaxial accelerometers in free-living adults (n≥100, 24 hours monitoring protocols). (2)Attendees of the inaugural ProPASS meeting were sent a survey focused on areas related to developing ProPASS: important terminology (Q1); accelerometry constructs (Q2); advantages and distinct contribution of the consortium (Q3); data pooling and harmonisation (Q4); data access and sharing (Q5 and Q6). RESULTS: (1) Eighty eligible articles were identified (22 primary studies; n~17 685). The accelerometers used most often were the ActivPAL3 and ActiGraph GT3X. The most commonly collected health outcomes were cardiometabolic and musculoskeletal. (2) None of the survey questions elicited the predefined 60% agreement. Survey responses recommended that ProPASS: use the term physical behaviour or movement behaviour rather than 'physical activity' for the data we are collecting (Q1); make only minor changes to ProPASS's accelerometry construct (Q2); prioritise developing standardised protocols/tools (Q4); facilitate flexible methods of data sharing and access (Q5 and Q6). CONCLUSIONS: Thigh-worn accelerometry is an emerging method of capturing movement and posture across the 24 hours cycle. In 2020, the literature is limited to 22 primary studies from high-income western countries. This work identified ProPASS's strategic directions-indicating areas where ProPASS can most benefit the field of research: use of clear terminology, refinement of the measured construct, standardised protocols/tools and flexible data sharing.
RESUMO
INTRODUCTION: The Need for Recovery (NFR) Scale facilitates the understanding of the factors that can lead to sustainable working and employability. Short-form scales can reduce the burden on researchers and respondents. Our aim was to create and validate a short-form Danish version of the NFR Scale. METHODS: Two datasets were used to conduct the exploratory and confirmatory analyses. This was done using qualitative and quantitative methods. The exploratory phase identified several short-form versions of the Danish NFR Scale and evaluated the quality of each through the assessment of content, construct and criterion validity, and responsiveness. These evaluations were then verified through the confirmatory analysis, using the second dataset. RESULTS: A short-form NFR scale consisting of three items (exhausted at the end of a work day, hard to find interest in other people after a work day, it takes over an hour to fully recover from a work day) showed excellent validity and responsiveness compared to the nine-item scale. Furthermore, a short-form consisting of just two items also showed excellent validity and good responsiveness. CONCLUSION: A short-form NFR scale, consisting of three items from the Danish NFR Scale, seems to be an appropriate substitute for the full nine-item scale.

BACKGROUND: Accurate tools for measuring physical activity are important for monitoring patients with chronic pain. However, these tools have not been properly validated in this population. OBJECTIVE: To determine the suitability of two physical activity measures for use in chronic pain populations. DESIGN: Longitudinal observational study. SETTING: Pain Management and Research Centre. PARTICIPANTS: Sixty-four patients presenting to the Pain Management and Research Centre with chronic pain. METHODS: Participants underwent a 3-week pain management program that included cognitive behavioral strategies, education, and multiple exercises sessions per day. Physical activity was measured by the Active Australia Survey and the Actigraph GT3X at the start and end of the program. Feasibility of the physical activity measures was assessed. Criterion validity and responsiveness between the measures was compared. Correlation of physical activity with self-rated global rating of change (GROC) scales in health were calculated. MAIN OUTCOME MEASUREMENTS: Minutes per day spent in low, moderate, and vigorous physical activity; global rating of change. RESULTS: Fifty-two percent (n = 33) and 78% (n = 50) of participants had valid Actigraph and Active Australia data, respectively, for both time points. For criterion validity and responsiveness correlations varied (rho = -.12-.52). All correlations between physical activity measures and GROC were small or negligible (rho ≤ .18). CONCLUSION: Feasibility of the Actigraph was poor compared to the Active Australia Survey. The criterion validity and responsiveness of the Active Australia Survey to the Actigraph was inconsistent and the relationship of both these measures to clinical outcomes was poor. However, limitations due to missing data mean that further research is required. LEVEL OF EVIDENCE: III.

OBJECTIVE: To quantify the relationship between the number of times articles are accessed on the Physiotherapy Evidence Database (PEDro) and the article characteristics. A secondary aim was to examine the relationship between accesses and the number of citations of articles. METHOD: The study was conducted to derive prediction models for the number of accesses of articles indexed on PEDro from factors that may influence an article's accesses. All articles available on PEDro from August 2014 to January 2015 were included. We extracted variables relating to the algorithm used to present PEDro search results (research design, year of publication, PEDro score, source of systematic review (Cochrane or non-Cochrane)) plus language, subdiscipline of physiotherapy, and whether articles were promoted to PEDro users. Three predictive models were examined using multiple regression analysis. Citation and journal impact factor were downloaded. RESULTS: There were 29,313 articles indexed in this period. We identified seven factors that predicted the number of accesses. More accesses were noted for factors related to the algorithm used to present PEDro search results (synthesis research (i.e., guidelines and reviews), recent articles, Cochrane reviews, and higher PEDro score) plus publication in English and being promoted to PEDro users. The musculoskeletal, neurology, orthopaedics, sports, and paediatrics subdisciplines were associated with more accesses. We also found that there was no association between number of accesses and citations. CONCLUSION: The number of times an article is accessed on PEDro is partly predicted by how condensed and high quality the evidence it contains is.

BACKGROUND: Before beginning a large and complex trial it is considered good practice to run a pilot study to assess the feasibility and acceptability so that quality is maintained and resources are not wasted. OBJECTIVE: To assesses the feasibility and acceptability of procedures for TOPS: Trial Of Prevention Strategies for low back pain. DESIGN: Randomised controlled pilot trial. METHODS: This is a trial of an 8 week, physiotherapist-led group exercise and education program for preventing recurrence of low back pain (LBP) in those recently recovered from LBP. We assessed the feasibility of recruitment and data-collection procedures, acceptability of the trial interventions and loss-to-follow up. RESULTS: The feasibility of recruitment, acceptability of the intervention and feasibility of physical activity data-collection procedures were all below anticipated levels. We enrolled 12 participants over 44 weeks, the adherence rate for the intervention group was 63% and valid physical activity data were obtained for 67% of the measurements. Follow-up methods for collection of LBP recurrence were successful with this information able to be collected for 100% of participants. CONCLUSION: In response to the pilot, modifications were made to the main trial protocol. We will increase recruitment by relaxing inclusion criteria and expanding recruitment sites to include workplaces, community centres and via social media. We will facilitate compliance by expanding treatment sites to provide more options for participants to access the program and we will limit missing data by checking the validity of baseline physical activity measures prior to enrolment. TRIAL REGISTRATION: The study was prospectively registered with the Australian and New Zealand Clinical Trials Registry (ref: ACTRN12614000706673).

The presence of bimodal outcome distributions has been used as a justification for conducting responder analyses, in addition to, or in place of analyses of the mean between-group difference, in clinical trials and systematic reviews of interventions for pain. The aim of this study was to investigate the distribution of participants' pain outcomes for evidence of bimodal distribution. We sourced data on participant outcomes from a convenience sample of 10 trials of nonsurgical interventions (exercise, manual therapy, medication) for spinal pain. We assessed normality using the Shapiro-Wilk test. When the Shapiro-Wilk test suggested non-normality we inspected distribution plots visually and attempted to classify them. To test whether responder analyses detected a meaningful number of additional patients experiencing substantial improvements we also calculated the risk difference and number needed to treat to benefit. We found no compelling evidence suggesting that outcomes were bimodally distributed for any of the intervention groups. Responder analysis would not meaningfully alter our interpretation of these data compared with the mean between group difference. Our findings suggest that bimodal distribution of outcomes should not be assumed in interventions for spinal pain and do not support the automatic prioritization of responder analysis over the between group difference in the evaluation of treatment effectiveness for pain. PERSPECTIVE: Secondary analysis of clinical trials of nonsurgical interventions for spinal pain found no evidence for bimodally distributed outcomes. The findings do not support the automatic prioritization of responder analyses over the average between group difference in the evaluation of treatment effectiveness for spinal pain.

BACKGROUND: Advice is widely considered an effective treatment for acute low back pain (LBP); however, details on what and how to deliver this intervention is less clear. PURPOSE: We assessed and compared clinical trials that test advice for acute LBP with practice guidelines for their completeness of reporting and concordance on the content, method of delivery, and treatment regimen of advice interventions. DESIGN/SETTING: Systematic review. METHODS: Advice randomized controlled trials were identified through a systematic search. Guidelines were taken from recent overviews of guidelines for LBP. Completeness of reporting was assessed using the Template for Intervention Description and Replication checklist. Thematic analysis was used to characterize advice interventions into topics across the aspects of content, method of delivery, and regimen. Concordance between clinical trials and guidelines was assessed by comparing the number of trials that found a statistically significant treatment effect for an intervention that included a specific advice topic with the number of guidelines recommending that topic. RESULTS: The median (interquartile range) completeness of reporting for clinical trials and guidelines was 8 (7-9) and 3 (2-4) out of nine items on the Template for Intervention Description and Replication checklist, respectively. Guideline recommendations were discordant with clinical trials for 50% of the advice topics identified. CONCLUSION: Completeness of reporting was less than ideal for randomized controlled trials and extremely poor for guidelines. The recommendations made in guidelines of advice for acute LBP were often not concordant with the results of clinical trials. Taken together, these findings mean that the potential clinical value of advice interventions for patients with acute LBP is probably not being realized.

STUDY DESIGN: A cross-sectional survey. OBJECTIVE: The aim of this study was to compare patients' and physiotherapists' views on triggers for low back pain (LBP) and to identify any novel factors not previously reported. SUMMARY OF BACKGROUND DATA: Most research on risk factors for LBP is guided by the views of clinicians and researchers, not patients. Consequently, potentially valuable information about risk factors for LBP is not available from those suffering the condition. This study aimed to compare patients' and physiotherapists' views on triggers for LBP and to identify any novel factors not previously reported. METHODS: One hundred two physiotherapists and 999 patients with a sudden, acute episode of LBP participated in this study. Participating physiotherapists were asked to nominate the most likely short-term risk factors to trigger a LBP episode. Similarly, patients were asked what they thought had triggered their onset of LBP. Responses were coded into risk factor categories and subcategories by 2 independent researchers. Endorsement of each category was compared using the Pearson Chi-square statistic. RESULTS: Both patients and physiotherapists endorsed biomechanical risk factors as the most important risk factor category (87.7% and 89.4%, respectively) and had similar levels of endorsement for 3 of the top 5 subcategories (lifting, bending, and prolonged sitting). There were significant differences in endorsement of awkward postures (13.4% vs 1.2%; Pâ<â0.001) sports injuries (15.9% vs 4.7%; Pâ<â0.001), physical trauma (3.4% vs 9.2%; Pâ<â0.001), and unaccustomed activity (2.3% vs 7.3%; Pâ<â0.001) by patients and physiotherapists, respectively. CONCLUSION: Overall, patients' and physiotherapists' views were remarkably similar. Both patients and physiotherapists endorsed lifting as the most important trigger for LBP and agreed on 3 of the top 5 (lifting, bending, and prolonged sitting). No new risk factors were suggested by patients. LEVEL OF EVIDENCE: 2.
