ABSTRACT
INTRODUCTION: Patients with low back pain may play an active role in the prescription of excessive spine imaging. OBJECTIVE: To determine the proportion of patients with low back pain who have beliefs not aligned with current evidence regarding the use of imaging and to identify factors associated with these beliefs. DESIGN: Secondary analysis of baseline data of a previously published randomized clinical trial. SETTING: Outpatient physical therapy clinic in a middle-income country. PATIENTS: Individuals with non-specific low back pain. METHODS: Outcome variables were two statements assessing the extent of patient agreement on the need for imaging in the management of low back pain. The predictor variables were age, educational level, duration of symptoms, disability level, pain intensity in the last 24 hours, beliefs about inevitable consequences of low back pain (assessed using the Back Belief Questionnaire), and having received imaging previously. Multivariable logistic models were used for data analysis. MAIN OUTCOME MEASURE(S): Level of agreement with Statement 1: X-rays or scans are necessary to get the best medical care for low back pain and Statement 2: Everyone with low back pain should have spine imaging. RESULTS: A total of 159 patients were included. Of these, 88.1% believed that imaging was necessary for the best medical care for low back pain and 62.9% believed that everyone with low back pain should obtain imaging. Lower scores on the Back Belief Questionnaire were associated with beliefs that imaging was necessary (odds ratio [OR] = 0.90, 95% confidence interval [CI]: 0.81, 0.99) and low education level was associated with the belief that everyone with low back pain should obtain imaging (OR = 3.03, 95% CI: 1.38, 6.61), after controlling for potential confounders. CONCLUSION: Nearly 90% of patients believe that spine imaging is necessary for the management of low back pain. Beliefs about the inevitable consequences of low back pain and low education level may be factors that need to be considered when developing new interventions.
ABSTRACT
BACKGROUND AND PURPOSE: People who live longer often live with multimorbidity. Nevertheless, whether the presence of multimorbidity affects pain and disability in older adults with chronic low back pain (LBP) remains unclear. The aim of this study was to investigate whether multimorbidity predicts pain intensity and disability at 6- and 12-month follow-ups in older adults with chronic LBP. METHODS: This was a prospective, longitudinal study with 6- and 12-month follow-ups. Participants with chronic LBP (age ≥ 60 years) were recruited and interviewed at baseline, 6 months, and 12 months. Self-reported measures included the number of comorbidities, assessed through the Self-Administered Comorbidity Questionnaire, pain intensity, assessed with the 11-point Numerical Rating Scale, and disability, assessed with the Roland-Morris Disability Questionnaire. Data were analyzed using univariate and multivariate regression models. RESULTS AND DISCUSSION: A total of 220 participants were included. The number of comorbidities predicted pain intensity at 6-month (ß= 0.31 [95% CI: 0.12 to 0.50]) and 12-month (ß= 0.29 [95% CI: 0.08 to 0.50]) follow-ups. The number of comorbidities predicted disability at 6-month (ß= 0.55 [95% CI: 0.20 to 0.90]) and 12-month (ß= 0.40 [95% CI: 0.03 to 0.77]) follow-ups. CONCLUSION: The number of comorbidities at baseline predicted pain and disability at 6-month and 12-month follow-ups in older adults with chronic LBP. These results highlight the role of comorbidities as a predictive factor of pain and disability in patients with chronic LBP, emphasizing the need for timely and continuous interventions in older adults with multimorbidity to mitigate LBP-related pain and disability.

OBJECTIVES: To investigate the effects of neuromuscular training, with minimal or no equipment, on physical performance of youth athletes. DESIGN: Systematic review with meta-analysis. METHODS: MEDLINE, EMBASE, CENTRAL, CINAHL, PEDro and SportDiscuss from inception to March/2022. SELECTION CRITERIA: youth athletes (15-24years), from Olympic team sports; used neuromuscular training 2-3 times/week for, at least, 6 weeks; had a control group/usual training group; physical performance as outcomes; randomized controlled trial. DATA SYNTHESIS: Pooled estimate of standardized mean difference (SMD), and 95% confidence interval (95%CI). RESULTS: Thirty-four studies (1111 participants) were included. Results showed that neuromuscular training improved power (SMD: 0.84 [95%CI: 0.58, 1.10]; n = 805; I2 = 64%), speed (SMD: -1.12 [95%CI: -1.68, -0.57]; n = 688; I2 = 90%) and agility (SMD: -1.21 [95%CI: -1.60, -0.83]; n = 571; I2 = 76%) compared to control group, but showed no difference between groups for muscle strength (Quadriceps SMD: 0.34 [95%CI: -0.02, 0.69]; n = 132; I2 = 0%, Hamstrings: SMD: 0.64 [95%CI: -0.04, 1.33]; n = 132; I2 = 71%), balance and flexibility. CONCLUSION: Clinically, neuromuscular training with minimal equipment may be useful for teams with limited resources to improve mainly athletes' power and agility, including those interventions that were designed to injury prevention. Future high-quality studies are likely to change these estimates.

BACKGROUND: A study using data from 2009 showed low prevalence and inadequate trial registration in physiotherapy. In 2013, a joint editorial recommended prospective registration in physiotherapy journals. Ten years later it is unclear whether the joint editorial achieved its intended benefit. OBJECTIVES: To investigate the proportion of randomized trials adequately registered and the extent of selective reporting of outcomes in trials of physiotherapy interventions published in 2019 and to compare these data with equivalent published data from 2009. DESIGN: Meta-research study. METHOD: A random sample of 200 trials published in 2019 was used. Evidence of registration was sought on trial registers and by contacting authors. Data from the article was compared with data from the trial registration. Data from this sample of trial published in 2019 were compared with equivalent published data from 2009. RESULTS: In 2019, the proportion of trials that were registered was 63% versus 34% in 2009 (absolute difference 29%). In 2019, 18% of the trials were prospectively registered compared to 6% in 2009 (absolute difference 12%). Unambiguous primary outcomes (i.e., method and timepoints of measurement clearly defined in the trial registry entry) were registered for 30% in 2019. Registration was adequate (i.e., prospective with unambiguous primary outcomes) for 8%, compared with 3% in 2009 (absolute difference 5%). Selective outcome reporting occurred in 73% of the trials in which it was assessable; in 2009 this proportion was 47% (absolute difference 26%). CONCLUSIONS: Registration of randomized trials in physiotherapy increased in the past decade, but it is still inadequate. More effort is still required to implement and enforce adequate registration.

INTRODUCTION: Investigating the determinants of physical activity (PA) is an important strategy for the promotion of healthy lifestyles, mainly with PA of a moderate-to-vigorous intensity, which provides several health benefits in adulthood. In this sense, it is not clear whether early sports practice (ESP) during childhood and adolescence could be associated with the habitual practice of PA of higher intensities in adulthood. OBJECTIVE: This study aimed to analyze the association of ESP in childhood and adolescence with different intensities of habitual PA in adulthood. METHODS: A sample of 264 community-dwelling adults were randomly selected (42.2 ± 17.0 years, 57.5% of women). ESP during childhood and adolescence was evaluated using retrospective questions. Weekly minutes of PA were assessed using accelerometry and classified according to intensity as light, moderate, moderate-to-vigorous, vigorous and very vigorous. The association of ESP with a high level of PA (above median) in each intensity was analyzed using binary regression models. RESULTS: The prevalence of ESP was 42.8% in childhood and 49.2% in adolescence. ESP in childhood was associated with a high level of very vigorous (OR: 2.48, p < 0.001) and vigorous PA (OR: 2.91, p < 0.001) in adulthood, but lost significance after adjustments by sex and age. ESP in adolescence was associated with a high level of very vigorous PA (OR: 1.99, p = 0.013) in the crude model and vigorous PA (OR: 2.21, p = 0.006), even after adjustments by age, sex and socioeconomic status. CONCLUSIONS: Engagement in sports practice during adolescence was associated with high levels of vigorous PA in adulthood and is an important period for healthy lifestyle promotion.

OBJECTIVES: To investigate the relationship between FOF and self-reported physical activity levels among older adults. DESIGN: Observational cross-sectional. SETTING AND PARTICIPANTS: Community-dwelling older adults aged 60 years and over and without cognitive deficits were recruited. MAIN OUTCOME MEASURES: Data collected included cognitive function [i.e., Mini Mental Status Examination (MMSE)], FOF [i.e., Iconographic Falls Efficacy Scale (Icon-FES); Falls Efficacy Scale - International (FES-I)], self-reported physical activity (i.e., Modified Baecke Questionnaire for Elderly People), history of falls, number of comorbidities and clinical tests of balance and mobility (i.e., Short Physical Performance Battery and the single leg stance test with closed and opened eyes). Multivariable linear regression was used to test whether FOF predicts self-reported physical activity levels. RESULTS: A total of 200 older adults living in the community were enrolled in this study. Our results showed that FOF, as measured by FES-I or Icon-FES, did not predict self-reported physical activity levels in community-dwelling older adults. CONCLUSION: Our results did not support previous evidence that higher FOF predicts lower levels of self-reported physical activity. These results question the role of FOF in influencing self-reported physical activity levels among community-dwelling older adults.

BACKGROUND: Physical activity plays an important role in the prognosis of chronic low back pain (LBP); however, whether physical activity predicts pain intensity and disability remains unknown. This study investigated whether objective and subjective physical activity measures predict pain intensity and disability levels 6 months later in patients with chronic LBP. METHODS: Patients with chronic LBP seeking care at 2 outpatient physiotherapy clinics were recruited. At baseline assessment, we collected anthropometric/sociodemographic data, duration of symptoms, pain intensity, disability, and physical activity (accelerometer and questionnaire). After 6 months, we reassessed pain and disability. Multivariable regression analyses were performed to investigate the association of physical activity measures with pain and disability at follow-up. RESULTS: A total of 179 patients with chronic LBP were included. High occupational physical activity at baseline predicted disability at 6-month follow-up (B = 1.22; 95% confidence interval, 0.21 to 2.21) after controlling for age and baseline disability, meaning that for every 1-point increase in occupational physical activity, disability increased on average by 1.22 point. The remaining physical activity measures showed no association with pain intensity or disability at follow-up. CONCLUSION: Higher perceived levels of occupational physical activity predicted higher disability levels at 6-month follow-up in patients with chronic LBP.

OBJECTIVES: To investigate whether physical activity is associated with enhanced immunogenicity of a SARS-CoV-2 inactivated vaccine (Coronavac) in patients with autoimmune rheumatic diseases (ARD) (n = 898) and in non-ARD (n = 197) individuals without pre-existing immunogenicity to SARS-CoV-2. METHODS: This was a prospective cohort study within an open-label, single-arm, phase 4 vaccination trial. Immunogenicity was assessed after vaccination by measuring seroconversion rates of total anti-SARS-CoV-2 S1/S2 IgG (SC), geometric mean titers of anti-S1/S2 IgG (GMT), factor-increase in GMT (FI-GMT), frequency of neutralizing antibody (NAb), and median neutralizing activity. Physical activity (active being defined as ≥ 150 min/week) and sedentary behavior (>8h/day) were assessed by questionnaire. RESULTS: Physically active ARD patients (n = 494) were younger and less frequently used prednisone/biologics than inactive patients (n = 404). After controlling for covariates, active patients exhibited greater SC (OR: 1.4 [95%CI: 1.1-2.0]), GMT (32% [95%CI: 8.8-60) and FI-GMT (33% [95%CI: 9.6-63%]) vs. inactive. Cluster analysis (physical activity/sedentary status) revealed greater GMT (43.0% [95% CI: 11.0-84.0%) and FI-GMT (48.0% [95%CI: 14.0-92.0%]) in active/non-sedentary vs. inactive/sedentary ARD patients. A dose-response was observed, with greater benefits for the group of patients performing ≥ 350 min/week of physical activity (OR: 1.6 [95%CI: 1.1-2.4]; 41% [95%CI: 10-80%]; 35% [95%CI: 4.3-74], for SC, GMT, and FI-GMT, respectively) vs. the least active group (≤30 min/week). Greater SC (OR: 9.9 [95%CI: 1.1-89.0]) and GMT (26% [95%CI: 2.2-56.0%]) were observed in active vs. inactive non-ARD. CONCLUSIONS: A physically active lifestyle may enhance SARS-CoV-2 vaccine immunogenicity, a finding of particular clinical relevance for immunocompromised patients.

BACKGROUND: Metabolic syndrome (MetS) is a combination of risk factors for cardiovascular disease and type 2 diabetes mellitus. The prevalence of MetS worldwide is increasing. There is no study investigating the economic burden of MetS, especially in developing countries, on medication-related expenditure. The aim of this study was to investigate the association of medication-related expenditures with MetS and to explore how physical activity (PA) may influence this association. METHODS: A total of 620 participants, 50 years or older, randomly selected in the city of Bauru, Brazil. Participants were followed from 2010 to 2014, and data on health care expenditure were collected annually. PA questionnaire was applied at baseline, 2 (2012), and 4 (2014) years later. RESULTS: Mean age was 64.7 (95% confidence interval, 64.1-65.3). MetS was associated with higher medication expenditure related to diseases of the circulatory (P <.01) and endocrine (P <.01) systems. MetS explained 17.2% of medication-related expenditures, whereas PA slightly attenuated this association, explaining 1.1% of all health care costs. CONCLUSION: This study demonstrates that MetS has a significant burden on health care expenditures among adults, whereas PA seems to affect this phenomenon significantly, but in low magnitude.

STUDY DESIGN: A systematic review and meta-analysis. OBJECTIVE: To evaluate the evidence on comparative effectiveness of advice to stay active versus supervised structured exercise in the management of sciatica. SUMMARY OF BACKGROUND DATA: Conservative management of sciatica usually includes interventions to promote physical activity in the form of advice to stay active or exercise, but there has been no systematic review directly comparing the effectiveness of these 2 approaches. METHODS: Data Sources included MEDLINE, CINAHL, EMBASE, and PEDro databases. Studies were randomized controlled trials comparing advice with exercise. Two independent reviewers extracted data and assessed methodological quality using the PEDro scale. Pain and disability data were extracted for all time points and converted to a common 0 to 100 scale. Data were pooled with a random effects model for short, intermediate, and long-term follow-ups. The GRADE approach was used to summarize the strength of evidence. RESULTS: Five trials were included in the meta-analysis, which showed a significant, although small effect favoring exercise over advice for reducing leg pain intensity in the short term (weighted mean difference: 11.43 [95% confidence interval, 0.71-22.16]) but no difference for disability (weighted mean difference: 1.45 [95% confidence interval, -2.86 to 5.76]). Furthermore, there was no difference at intermediate and long-term follow-ups between advice and exercise for patient-relevant outcomes. CONCLUSION: There is low-quality evidence (GRADE) that exercise provides small, superior effects compared with advice to stay active on leg pain in the short term for patients experiencing sciatica. However, there is moderate-quality evidence showing no difference between advice to stay active and exercise on leg pain and disability status in people with sciatica in the long term. LEVEL OF EVIDENCE: 1.
