Clinical care standards for the management of low back pain: a scoping review

The objective of this study is to compare and contrast the quality statements and quality indicators across clinical care standards for low back pain. Searches were performed in Medline, guideline databases, and Google searches to identify clinical care standards for the management of low back pain targeting a multidisciplinary audience. Two independent reviewers reviewed the search results and extracted relevant information from the clinical care standards. We compared the quality statements and indicators of the clinical care standards to identify the consistent messages and the discrepancies between them. Three national clinical care standards from Australia, Canada, and the United Kingdom were included. They provided from 6 to 8 quality statements and from 12 to 18 quality indicators. The three standards provide consistent recommendations in the quality statements related to imaging, and patient education/advice and self-management. In addition, the Canadian and Australian standards also provide consistent recommendations regarding comprehensive assessment, psychological support, and review and patient referral. However, the three clinical care standards differ in the statements related to psychological assessment, opioid analgesics, non-opioid analgesics, and non-pharmacological therapies. The three national clinical care standards provide consistent recommendations on imaging and patient education/advice, self-management of the condition, and two standards (Canadian and Australian) agree on recommendations regarding comprehensive assessment, psychological support, and review and patient referral. The standards differ in the quality statements related to psychological assessment, opioid prescription, non-opioid analgesics, and non-pharmacological therapies.

Does the Number of Comorbidities Predict Pain and Disability in Older Adults With Chronic Low Back Pain? A Longitudinal Study With 6- and 12-Month Follow-ups

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 (β= 0.31 [95% CI: 0.12 to 0.50]) and 12-month (β= 0.29 [95% CI: 0.08 to 0.50]) follow-ups. The number of comorbidities predicted disability at 6-month (β= 0.55 [95% CI: 0.20 to 0.90]) and 12-month (β= 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.

The efficacy of neuromuscular training, with minimal or no equipment, on performance of youth athletes: A systematic review with meta-analysis

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.

Process evaluation of the implementation of an evidence-based model of care for low back pain in Australian emergency departments

BACKGROUND

The Sydney Health Partners Emergency Department (SHaPED) trial targeted ED clinicians and evaluated a multifaceted strategy to implement a new model of care. The objective of this study was to investigate attitudes and experiences of ED clinicians as well as barriers and facilitators for implementation of the model of care.

DESIGN

A qualitative study.

METHODS

The EDs of three urban and one rural hospital in New South Wales, Australia participated in the trial between August and November 2018. A sample of clinicians was invited to participate in qualitative interviews via telephone and face-to-face. The data collected from the interviews were coded and grouped in themes using thematic analysis methods.

RESULTS

Non-opioid pain management strategies (i.e., patient education, simple analgesics, and heat wraps) were perceived to be the most helpful strategy for reducing opioid use by ED clinicians. However, time constraints and rotation of junior medical staff were seen as the main barriers for uptake of the model of care. Fear of missing a serious pathology and the clinicians' conviction of a need to provide something for the patient were seen as barriers to reducing lumbar imaging referrals. Other barriers to guideline endorsed care included patient's expectations and characteristics (e.g., older age and symptoms severity).

CONCLUSIONS

Improving knowledge of non-opioid pain management strategies was seen as a helpful strategy for reducing opioid use. However, clinicians also raised barriers related to the ED environment, clinicians' behaviour, and cultural aspects, which should be addressed in future implementation efforts.

Sleep Quality Predicts Functional Disability in Older Adults with Low Back Pain: A Longitudinal Study

Low back pain (LBP) and sleep quality are two very prevalent complaints in the older population. However, little is known about the prognostic relationship between sleep quality and disability in older adults with LBP. The aim of this study was to examine the association between sleep quality and disability in older adults with LBP. This was a longitudinal study over a 6-month period. Older adults with LBP in the last 12 weeks and who had preserved cognitive functions were recruited. The questionnaires used were the Pittsburgh Sleep Quality Index and the Roland Morris Disability Questionnaire. At baseline, we collected information on demographic/anthropometric variables, cognitive status, depression, daytime sleepiness, and comorbidities. Linear regression adjusted for potential covariates were performed. Poor sleep at baseline predicted higher disability after 6 months [β = 0.30 (CI95%:0.07 to 0.55)]. Our results support the existence of an important relationship between sleep and disability in older adults with LBP.

The bidirectional association between sleep quality and low back pain in the older adults: a longitudinal observational study

OBJECTIVE

To investigate the bidirectional relationship by determining whether baseline sleep quality predicts pain intensity and whether baseline pain intensity predicts sleep quality in older people with chronic LBP.

DESIGN

A prospective longitudinal cohort study with a 6-month follow-up.

PARTICIPANTS

Older adults with LBP aged 60 years or more.

SETTINGS

Community.

MAIN OUTCOMES

Data collection occurred at baseline and at 6 months follow-up. Pain intensity and sleep quality were measured in both time points of assessment using the 0-10 Numerical Pain Rating Scale and the Pittsburg Sleep Quality Index. At baseline we also collected information on demographic anthropometric variables, cognitive status, depression and comorbidities. Multivariable linear regression analyses adjusted for potential covariates were performed.

RESULTS

A total of 215 people with LBP were recruited. Poor sleep quality at baseline predicted (Beta coefficient = 0.18, 95% CI 0.07 to 0.30) high pain intensity at 6-month follow-up. High pain intensity at baseline predicted (Beta coefficient = 0.14, 95%CI 0.01 to 0.26) poor sleep quality 6 months later.

CONCLUSION

Our findings give some support to bidirectional relationship between pain and sleep quality in older people with LBP. This bidirectional relationship may be used as a prognostic information by clinicians when managing patients with LBP.

Effectiveness of brief patient information materials for promoting correct beliefs about imaging and inevitable consequences of low back pain: A randomised controlled trial

OBJECTIVE

To investigate what format for providing patient information (i.e. written summary, infographic or video animation) is most effective for promoting correct beliefs about imaging and inevitable consequences of low back pain (LBP).

DESIGN

Randomised controlled trial.

SETTING/PATIENTS

One hundred and fifty-nine patients with non-specific LBP were recruited from outpatient physiotherapy clinics.

INTERVENTION

Participants were randomised to receive patient information in one of three formats: video animation, infographic or written summary. Patients were allowed to read or watch the materials for up to 20 min.

MEASUREMENTS

Outcome were assessed before and immediately after the intervention. The primary outcome was the Back Beliefs Questionnaire. The secondary outcome was beliefs about imaging for LBP assessed by two questions.

RESULTS

All 159 patients completed the study. Our findings revealed no difference between groups for the Back Beliefs Questionnaire. Correct beliefs about imaging were more likely with the infographic than the video animation (Question 1- Odds Ratio [OR] = 3.9, 95% confidence interval [CI]: 1.7, 8.7; Question 2- OR = 6.8, 95%CI: 2.7, 17.2) and more likely with the written summary than the video animation (Question 1- OR = 3.3, 95%CI: 1.5, 7.4; Question 2- OR = 3.7, 95%CI: 1.6, 8.5). No difference between infographic and written summary formats were reported for the questions assessing LBP imaging beliefs.

CONCLUSION

The three materials were equally effective in improving patient's general beliefs about LBP care. However, the traditional written summary or infographic formats were more effective than the video animation format for improving beliefs about imaging for LBP.

Prevalence of overuse injuries in athletes from individual and team sports: A systematic review with meta-analysis and GRADE recommendations

BACKGROUND

Overuse injuries result from the cumulative process of repetitive microtrauma and overload on the musculoskeletal system, which causes tissue damage. Therefore, these injuries may have long-term negative consequences that decrease an athlete's performance.

OBJECTIVE

To estimate the prevalence of overuse injuries in individual and team sports.

METHODS

Searches on MEDLINE, EMBASE, SPORTDiscus, and CINAHL from the first registration to February 2021 and hand-searching identified studies investigating the prevalence of overuse injuries in athletes from individual and team sports. Meta-analysis was conducted and the GRADE system summarized the overall quality of evidence. This review was registered in PROSPERO (CRD42019135665).

RESULTS

Seventeen studies were included and pooling of 24 704 participants (22 748 of individual sports and 1.956 of team sports). Data from point- and period-prevalence of overuse injuries in individual and team sports were obtained. Pooled period-prevalence of overuse injuries in individual and team sports was 42.0% (95% CI: 30.0, 55.0) and 33.0% (95% CI: 21.0, 49.0), respectively. Another four studies investigated point-prevalence. The overall quality of evidence for the period-prevalence was of moderate quality. Sensitivity analyses suggested that different joints based in individual and team sports tended to increase the estimated prevalence of overuse injuries.

CONCLUSION

Athletes, clinicians, sport teams, and policymakers should be aware of the high prevalence of overuse injuries in athletes, especially, in athletes from individual sports. Current moderate-quality evidence shows that future high-quality studies are likely to impact on the estimated prevalence.

Characteristics Associated With People With Chronic Low Back Pain Meeting Physical Activity Guidelines and Recommendations for Sedentary Behavior: A Cross-Sectional Study

OBJECTIVE

The purpose of this study was to identify factors associated with meeting physical activity guidelines and sedentary recommendations in people with chronic low back pain (LBP).

METHODS

This was a cross-sectional study including 171 people with chronic LBP. Trained assessors collected information regarding demographic, anthropometric, and clinical data. Physical activity levels and sedentary time were objectively measured using a tri-axial accelerometer. Participants were classified as being physically active (ie, performing at least 150 minutes of moderate or 75 minutes of vigorous physical activity per week) and sedentary (ie, more than 8 hours of time spent in sedentary activities per day). Multivariable logistic regression analyses were used to determine the association of being physically active or sedentary with the range of demographic, anthropometric and clinical variables.

RESULTS

Our results showed that although lower body mass index (odds ratio [OR] = 0.91; 95% CI: 0.85-0.98) and higher self-reported levels of leisure time physical activity (OR = 3.46; 95% CI: 1.94-6.15) were associated with being physically active, lower self-reported levels of physical activity at work (OR = 0.56; 95% CI: 0.39-0.81) was associated with being sedentary.

CONCLUSION

Our findings showed that, in people with LBP, lower body mass index and higher levels of leisure time physical activity may be important factors for identifying those physically active. In contrast, lower levels of physical activity at work may be considered when identifying sedentary people with LBP. Future studies should consider these factors when designing interventions aiming to promote physical activity and decrease sedentary behavior in this population.

Recommendations for Diagnosis and Treatment of Lumbosacral Radicular Pain: A Systematic Review of Clinical Practice Guidelines

The management of patients with lumbosacral radicular pain (LRP) is of primary importance to healthcare professionals. This study aimed to: identify international clinical practice guidelines on LRP, assess their methodological quality, and summarize their diagnostic and therapeutic recommendations. A systematic search was performed (August 2019) in MEDLINE, PEDro, National Guideline Clearinghouse, National Institute for Health and Clinical Excellence (NICE), New Zealand Guidelines Group (NZGG), International Guideline Library, Guideline central, and Google Scholar. Guidelines presenting recommendations on diagnosis and/or treatment of adult patients with LRP were included. Two independent reviewers selected eligible guidelines, evaluated quality with Appraisal of Guidelines Research & Evaluation (AGREE) II, and extracted recommendations. Recommendations were classified into 'should do', 'could do', 'do not do', or 'uncertain'; their consistency was labelled as 'consistent', 'common', or 'inconsistent'. Twenty-three guidelines of varying quality (AGREE II overall assessment ranging from 17% to 92%) were included. Consistent recommendations regarding diagnosis are ('should do'): Straight leg raise (SLR) test, crossed SLR test, mapping pain distribution, gait assessment, congruence of signs and symptoms. Routine use of imaging is consistently not recommended. The following therapeutic options are consistently recommended ('should do'): educational care, physical activity, discectomy under specific circumstances (e.g., failure of conservative treatment). Referral to a specialist is recommended when conservative therapy fails or when steppage gait is present. These recommendations provide a clear overview of the management options in patients with LRP.

Physical activity across life stages and sleep quality in adulthood - an epidemiological study

OBJECTIVE

To analyze the association between the continuous physical activity (PA) at different life stages with sleep quality in adults.

METHODS

This is an observational study with a cross-sectional design. A sample of 843 adults (61.7% female) with a mean age of 56.6 (±18.3) years was randomly selected. The PA at different life stages was assessed retrospectively in childhood and adolescence, and the current PA was assessed by Baecke Physical Activity Questionnaire. Sleep quality was assessed using the Mini-Sleep Questionnaire. Variables of sex, age group, ethnicity, socioeconomic status, and current physical activity were covariates. The association between continuous PA at different life stages with sleep quality was analyzed by binary logistic regression models.

RESULTS

Overweight adults who practiced PA in adolescence were 46% less likely to have poor sleep quality when compared to those who did not practice physical activity in this life stage (Odds ratio = 0.54, p = 0.031). Adults who continued to practice PA at youth and adulthood were 49% less likely to have poor sleep quality when compared to those without continuous PA (Odds ratio = 0.51, p = 0.009).

CONCLUSIONS

Poor sleep quality was negatively associated with continuous PA between youth and adulthood in overall sample and negatively associated with PA in adolescence among overweight adults.

Interventions Promoting Physical Activity Among Older Adults: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Frequent participation in physical activity (PA) has benefits across the lifespan but is particularly important for older adults. PA levels are either measured by objective or self-reported survey methods. Objective PA measurement is used to increase accuracy. This systematic review investigated the effect of physical activity-based interventions on objectively measured PA levels among community-dwelling adults aged 60 years and older.

RESEARCH DESIGN AND METHODS

Literature searches were conducted in five electronic databases and four clinical trial registries. Randomized controlled trials investigating the effect of physical activity-based interventions on objectively measured PA levels (e.g., accelerometers or pedometers) in community-dwelling adults aged 60 years and older compared with no/minimal intervention were considered eligible. Data were pooled using the most conservative estimates reported from each study using the standardized mean difference (SMD). Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to evaluate the overall quality of the evidence.

RESULTS

Fourteen published trials and 3 ongoing trials were identified. There were significant effects favoring physical activity-based interventions compared with minimal intervention at short-term (less than or equal to 3 months) (SMD: 0.30, 95% CI: 0.17 to 0.43) and intermediate-term (more than 3 months and less than 12 months; SMD: 0.27, 95% CI: 0.06 to 0.49) follow-ups. The quality of evidence was moderate according to GRADE (downgraded for risk of bias).

DISCUSSION AND IMPLICATIONS

Our findings suggest that physical activity-based interventions may increase objectively measured PA levels in community-dwelling older adults. Further studies are still needed to identify the optimal dose, intensity, and mode of delivery of physical activity-based interventions.

Epidural Corticosteroid Injections for Sciatica: An Abridged Cochrane Systematic Review and Meta-Analysis

STUDY DESIGN

Systematic with meta-analysis OBJECTIVES.: The aim of this study was to investigate the efficacy and safety of epidural corticosteroid injections compared with placebo injection in reducing leg pain and disability in patients with sciatica.

SUMMARY OF BACKGROUND DATA

Conservative treatments, including pharmacological and nonpharmacological treatments, are typically the first treatment options for sciatica but the evidence to support their use is limited. The overall quality of evidence found by previous systematic reviews varies between moderate and high, which suggests that future trials may change the conclusions. New placebo-controlled randomized trials have been published recently which highlights the importance of an updated systematic review.

METHODS

The searches were performed without language restrictions in the following databases from 2012 to 25 September 2019: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, PubMed, Embase, CINAHL, PsycINFO, International Pharmaceutical Abstracts, and trial registers. We included placebo-controlled randomized trials investigating epidural corticosteroid injections in patients with sciatica. The primary outcomes were leg pain intensity and disability. The secondary outcomes were adverse events, overall pain, and back pain intensity. We grouped similar trials according to outcome measures and their respective follow-up time points. Short-term follow-up (>2 weeks but ≤3 months) was considered the primary follow-up time point due to the expected mechanism of action of epidural corticosteroid injection. Weighted mean differences (MDs) and risk ratios (RRs) with their respective 95% confidence intervals (CIs) were estimated. We assessed the overall quality of evidence using the GRADE approach and conducted the analyses using random effects.

RESULTS

We included 25 clinical trials (from 29 publications) providing data for a total of 2470 participants with sciatica, an increase of six trials when compared to the previous review. Epidural corticosteroid injections were probably more effective than placebo in reducing short-term leg pain (MD -4.93, 95% CI -8.77 to -1.09 on a 0-100 scale), short-term disability (MD -4.18, 95% CI: -6.04 to -2.17 on a 0-100 scale) and may be slightly more effective in reducing short-term overall pain (MD -9.35, 95% CI -14.05 to -4.65 on a 0-100 scale). There were mostly minor adverse events (i.e., without hospitalization) after epidural corticosteroid injections and placebo injections without difference between groups (RR 1.14, 95% CI: 0.91-1.42). The quality of evidence was at best moderate mostly due to problems with trial design and inconsistency.

CONCLUSION

A review of 25 placebo-controlled trials provides moderate-quality evidence that epidural corticosteroid injections are effective, although the effects are small and short-term. There is uncertainty on safety due to very low-quality evidence.

Association of musculoskeletal pain with poor sleep quality in public school teachers

BACKGROUND

Teachers perform repetitive movements all day, which can cause pain in body regions. This article analyzes the association of pain with sleep quality in this population.

OBJECTIVE

The objective of the study was to analyze the relationship of musculoskeletal pain and sleep quality in teachers from public schools.

METHODS

The sample consisted of 242 teachers, selected in a random process. Musculoskeletal pain and sleep quality were evaluated by using a questionnaire. The association between sleep quality and musculoskeletal pain was evaluated using the chi-square test. The magnitude of the associations was verified by Binary Logistic Regression, adjusted by sex, age, BMI, and socioeconomic status.

RESULTS

Teachers with poor sleep quality presented higher body mass index (BMI) values when compared to teachers with good sleep quality (27.9 vs 26.0, p = 0.012). Teachers with poor sleep quality were approximately twice as likely to report thoracic pain (OR = 2.16[95% CI = 1.12-4.16]), wrist pain (OR = 3.28[95% CI = 1.18-9.07]), low back pain (OR = 3.09[95% CI = 1.29-7.41]), and ankle/foot pain (OR = 2.83[95% CI = 1.32-6.08]).

CONCLUSIONS

Teachers with poor sleep quality were approximately twice as likely to present pain in several body parts. Our findings revealed that poor sleep quality was significantly associated with musculoskeletal pain in Brazilian teachers of public schools, regardless of confounding factors.

Continuity of physical activity practice from childhood to adolescence is associated with lower neck pain in both sexes and lower back pain in girls

BACKGROUND

The literature on physical activity practice through sports as a protective factor for back pain in adolescents is conflicting. However, few studies have aimed to verify if continuity of the practice of physical activity from childhood to adolescence may be related to lower chances of back pain in adolescents.

OBJECTIVES

The objective of this study was to analyze the association between physical activity practice from childhood to adolescence and back pain in adolescents.

METHODS

The random sample was composed of 870 adolescents with a mean age of 13.7 ± 2.0 years. The continuity of physical activity practice was assessed through the continuity of sports practice from childhood to adolescence. Pain in the neck and low back were evaluated through a questionnaire.

RESULTS

The prevalence of neck pain and low back pain in boys was 17.5% and in girls was 20.9% for neck pain and 21.9% for low back pain. Physical activity practice during childhood to adolescence was a protective factor for neck pain (OR = 0.57 [CI = 0.35-0.94]) and low back pain (OR = 0.53 [CI = 0.33-0.86]) in girls and neck pain in boys (OR = 0.52 [CI = 0.30-0.90]), even after adjusting for confounding factors.

CONCLUSION

Girls with physical activity practice during childhood to adolescence were less likely to develop neck pain and back pain when compared to girls who did not maintain practice of physical activity. Similar results were observed in boys considering neck pain.

Measurement Properties of the Sedentary Behavior Questionnaire in Patients with Chronic Nonspecific Low Back Pain

BACKGROUND

The Sedentary Behavior Questionnaire (SBQ) is a brief and easy instrument to measure time spent on sedentary activities; however, no study has investigated the reliability and validity of this questionnaire in people with chronic low back pain (LBP).

OBJECTIVE

To investigate the internal consistency, test-retest reliability, measurement error, construct validity, and interpretability of the SBQ against data derived from an accelerometer in patients with nonspecific chronic LBP.

STUDY DESIGN

Cross-sectional study.

SETTING

Outpatient physiotherapy clinic.

PATIENTS

Seventy-five patients aged between 18 and 60 years (mean age, 42 years old) with nonspecific chronic LBP were recruited for this study.

INTERVENTIONS

Not applicable.

METHODS

The Cronbach's α was calculated to investigate the internal consistency of the SBQ and the intraclass correlation coefficient (ICC) was calculated to investigate the reliability of the SBQ between two administrations separated by a 1-week interval. Measurement error was assessed calculating the SEM and minimal detectable change (MDC). Spearman correlation (r) was calculated to investigate the construct validity using hypothesis testing. Interpretability was investigated using ceiling and floor effects.

RESULTS

The Cronbach's α of the SBQ total score was 0.92, indicating homogeneity among the items of the instrument. The reliability of the SBQ was excellent (ICC > 0.75), without any evidence of ceiling and floor effects. Regarding measurement error, the total score of the SBQ showed an SEM and MDC of 109.8 minutes per day and 304.4 minutes per day, respectively. However, there were no correlations of the SBQ domains or the total score with the accelerometer-measured sedentary time (r < 0.25).

CONCLUSION

The SBQ is a reliable tool for quantifying time spent in sedentary activities of patients with chronic LBP. The SBQ showed poor construct validity compared to the accelerometer-measured sedentary time, which indicates that patients may underestimate their time spent in sedentary activities.

Effect of Senior Dance (DanSE) on Fall Risk Factors in Older Adults: A Randomized Controlled Trial

BACKGROUND

Older people's participation in structured exercise programs to improve balance and mobility is low. Senior Dance is an alternative option, as it may provide a safe and fun way of targeting balance.

OBJECTIVE

The aim was to investigate the effect of Senior Dance on balance, mobility, and cognitive function compared with a control intervention.

DESIGN

The study was a randomized controlled trial.

SETTING/PATIENTS

Eighty-two community-dwelling older people aged 60 years or over and cognitively intact were recruited in Brazil.

INTERVENTION

Participants were randomly allocated to 2 groups: Dance plus education (intervention group) and education alone (control group). The Senior Dance program consisted of 12 weeks of twice-weekly group-based dance classes. Participants in both groups attended a single 1-hour educational session on prevention of falls.

MEASUREMENTS

The primary outcome was single-leg stance with eyes closed. Secondary outcomes were timed sit-to-stand test, standing balance test, timed 4-m walk, and cognitive function tests, for example, Trail Making Test and Montreal Cognitive Assessment.

RESULTS

Of the 82 participants randomized, 71 (87%) completed the 12-week follow-up. Single-leg stance with eyes closed (primary outcome) improved in the Senior Dance group (mean difference [MD] = 2.3 seconds, 95% confidence interval [CI] = 1.1 to 3.6) compared with the control group at follow-up. Senior Dance group performed better in the standing balance tests (MD = 3.7 seconds, 95% CI = 0.6 to 6.8) and were faster in the sit-to-stand test (MD = - 3.1 seconds, 95% CI = -4.8 to -1.4) and 4-m walk test (MD = -0.6 seconds, 95% CI = -1.0 to -0.1). There were no significant between-group differences for cognitive function tests.

LIMITATIONS

Participants and therapists were not blinded.

CONCLUSION

Senior Dance was effective in improving balance and mobility but not cognitive function in community-dwelling older people.

Implementation of Early Intervention Protocol in Australia for 'High Risk' Injured Workers is Associated with Fewer Lost Work Days Over 2 Years Than Usual (Stepped) Care

Purpose To evaluate whether a protocol for early intervention addressing the psychosocial risk factors for delayed return to work in workers with soft tissue injuries would achieve better long-term outcomes than usual (stepped) care. Methods The study used a controlled, non-randomised prospective design to compare two case management approaches. For the intervention condition, workers screened within 1-3 weeks of injury as being at high risk of delayed returned to work by the Örebro Musculoskeletal Pain Screening Questionnaire-short version (ÖMPSQ-SF) were offered psychological assessment and a comprehensive protocol to address the identified obstacles for return to work. Similarly identified injured workers in the control condition were managed under usual (stepped) care arrangements. Results At 2-year follow-up, the mean lost work days for the Intervention group was less than half that of the usual care group, their claim costs were 30% lower, as was the growth trajectory of their costs after 11 months. Conclusions The findings supported the hypothesis that brief psychological risk factor screening, combined with a protocol for active collaboration between key stakeholders to address identified psychological and workplace factors for delayed return to work, can achieve better return on investment than usual (stepped) care.

Co-occurrence of Chronic Musculoskeletal Pain and Cardiovascular Diseases: A Systematic Review with Meta-analysis

Objective

To determine the magnitude of the association between cardiovascular disease and chronic musculoskeletal pain.

Design

Systematic review with meta-analysis.

Methods

A comprehensive search was performed in five electronic databases. Population-based studies reporting the prevalence of cardiovascular diseases in adults stratified by chronic musculoskeletal pain status were considered eligible. Two independent reviewers performed the screening of the records following the inclusion criteria, extracted data, and evaluated the risk of bias of the included studies using an assessment tool of risk of bias for observational studies. In addition, we assessed the overall quality of evidence using an adaptation of the GRADE approach for prognosis.

Results

Twenty studies were included in this review. There was high-quality evidence that people with chronic musculoskeletal pain are 1.91 times more likely to report having a cardiovascular disease compared with those without chronic musculoskeletal pain (risk ratio = 1.91, 95% confidence interval = 1.64–2.21).

Conclusions

Our findings demonstrated associations between chronic musculoskeletal pain and any cardiovascular diseases. Future studies are still warranted to better understand the association between chronic musculoskeletal pain and the specific types of cardiovascular diseases.

Effects of active video games on children and adolescents: A systematic review with meta-analysis

OBJECTIVE

To investigate the effectiveness of active video games (AVGs) on obesity-related outcomes and physical activity levels in children and adolescents.

DESIGN

Systematic review with meta-analysis.

METHODS

Literature search was performed in five electronic databases and the main clinical trials registries. Randomized controlled trials investigating the effect of AVGs compared with no/minimal intervention on obesity-related outcomes (body mass index [BMI], body weight, body fat, and waist circumference) and physical activity levels of children and adolescents were eligible. Two independent reviewers extracted the data of each included study. PEDro scale was used to assess risk of bias and GRADE approach to evaluate overall quality of evidence. Pooled estimates were obtained using random effect models.

RESULTS

Twelve studies were considered eligible for this review. Included studies mostly reported outcome data at short-term (less or equal than three months) and intermediate-term follow-up (more than 3 months, but <12 months). AVGs were more effective than no/minimal intervention in reducing BMI/zBMI at short-term (SMD = -0.34; 95% CI: -0.62 to -0.05) and intermediate-term follow-up (SMD = -0.36; 95% CI: -0.01 to -0.71). In addition, AVGs were more effective in reducing body weight compared with no/minimal intervention at intermediate-term follow-up (SMD = -0.25; 95% CI: -0.46 to -0.04). Regarding physical activity levels, AVGs were not more effective compared with minimal intervention at short-term and intermediate-term follow-up.

CONCLUSIONS

Our review identified that AVGs were better than minimal intervention in reducing BMI and body weight, but not for increasing physical activity in young people.

Predicting Return to Work in a Heterogeneous Sample of Recently Injured Workers Using the Brief ÖMPSQ-SF

Purpose (1) to examine the ability of the Örebro Musculoskeletal Pain Screening Questionnaire-short version (ÖMPSQ-SF) to predict time to return to pre-injury work duties (PID) following a work-related soft tissue injury (regardless of body location); and (2) to examine the appropriateness of 50/100 as a suitable cut-off score for case identification. Methods Injured workers (IW) from six public hospitals in Sydney, Australia, who had taken medically-sanctioned time off work due to their injury, were recruited by insurance case managers within 5-15 days of their injury. Eligible participants (N = 213 in total) were administered the ÖMPSQ-SF over the telephone by the case manager. For objective (1) Cox proportional hazards regression analysis was used to predict days to return to PID using the ÖMPSQ-SF. For objective (2) receiver operator characteristic (ROC) analysis was used to determine the ÖMPSQ-SF total score that optimises sensitivity and specificity in detecting whether or not participants had returned to PID within 2-7 weeks. Results The total ÖMPSQ-SF score significantly predicted number of days to return to PID, such that for every 1-point increase in the total ÖMPSQ-SF score the predicted chance of returning to work reduced by 4% (i.e., hazard ratio = 0.96), p < 0.001. Sensitivity and specificity for the ROC analysis comparing ÖMPSQ-SF total score to return to PID within 2-7 weeks suggested 48 as the optimal cut off (sensitivity = 0.65, specificity = 0.79). Conclusion The results provide strong support for the use of the ÖMPSQ-SF in an applied setting for identifying those IW likely to have delayed RTW when administered within 15 days of the injury. While a score of 48/100 was the optimal cut point for sensitivity and specificity, pragmatically, 50/100 should be acceptable as a cut-off in future studies of this type.

Are plain-language summaries included in published reports of evidence about physiotherapy interventions? Analysis of 4421 randomised trials, systematic reviews and guidelines on the Physiotherapy Evidence Database (PEDro)

BACKGROUND

A plain-language summary is a short and clearly stated version of a study's results using non-scientific vocabulary that provide many advantages for patients and clinicians in the process of shared decision-making.

OBJECTIVES

The primary objective was to investigate the extent to which published reports of physiotherapy interventions provide plain-language summaries. We investigate as the secondary objectives if the available plain-language summaries are at a suitable reading level for a lay person and if inclusion of plain-language summaries in these reports is increasing over time and is associated with trial quality (i.e. PEDro score).

DATA SOURCES

All 4421 randomised controlled trials (RCT), systematic reviews and clinical practice guidelines that included plain-language summaries indexed on Physiotherapy Evidence Database (PEDro) were included.

MAIN OUTCOME MEASURES

Proportion of published reports with plain-language summaries, Flesch Reading Ease Score (FRES) and the Flesch-Kincaid Grade Level (FKGL).

RESULTS

The number of published reports with a plain-language summary doubled in the last 6 years. From a total of 34,444 reports indexed on PEDro, only 4421 reports had English plain-language summaries. RCTs with plain-language summaries had higher PEDro scores than RCTs without plain-language summaries (mean difference=0.8 points, 95%CI 0.7 to 0.8). Only 2% of reports were considered at a suitable reading level by the FKGL formula and 0.1% by the FRES formula.

CONCLUSIONS

Although the publication of plain-language summaries is increasing over time, the current number corresponds to only 13% of all published reports. In addition the majority of plain-language summaries are written at an advanced reading level.

Association Between Clinical Tests Related to Motor Control Dysfunction and Changes in Pain and Disability After Lumbar Stabilization Exercises in Individuals With Chronic Low Back Pain

OBJECTIVE

To investigate whether clinical tests used to detect motor control dysfunction can predict improvements in pain and disability in patients with chronic nonspecific low back pain (LBP) who have undergone an 8-week lumbar stabilization exercise program.

STUDY DESIGN

A prospective cohort study.

SETTING

Outpatient physical therapy university clinic.

PARTICIPANTS

Seventy people with chronic nonspecific LBP were recruited, and 64 completed the exercise program (N=64).

INTERVENTIONS

The lumbar stabilization program was provided twice a week for 8 weeks.

MAIN OUTCOME MEASURES

Pain intensity (11-point numerical rating scale) and disability (Roland Morris Disability Questionnaire) and clinical tests, such as the Deep Muscle Contraction (DMC) scale, Clinical Test of Thoracolumbar Dissociation (CTTD), and Passive Lumbar Extension (PLE) test. Univariate and multivariate linear regression models were used in the prediction analysis.

RESULTS

Mean changes in pain intensity and disability following the 8-week stabilization program were -3.8 (95% confidence interval [CI], -3.2 to -4.4) and -7.4 (95% CI, -6.3 to -8.5), respectively. Clinical test scores taken at baseline did not predict changes in pain and disability at 8-week follow-up.

CONCLUSION

Our findings revealed that the DMC scale, CTTD, PLE test, clinical tests used to assess motor control dysfunction, do not predict improvements in pain and disability in patients with chronic nonspecific LBP following an 8-week lumbar stabilization exercise program.

Clinical practice guidelines for the management of non-specific low back pain in primary care: an updated overview

OBJECTIVE

The aim of this study was to provide an overview of the recommendations regarding the diagnosis and treatment contained in current clinical practice guidelines for patients with non-specific low back pain in primary care. We also aimed to examine how recommendations have changed since our last overview in 2010.

METHOD

The searches for clinical practice guidelines were performed for the period from 2008 to 2017 in electronic databases. Guidelines including information regarding either the diagnosis or treatment of non-specific low back pain, and targeted at a multidisciplinary audience in the primary care setting, were considered eligible. We extracted data regarding recommendations for diagnosis and treatment, and methods for development of guidelines.

RESULTS

We identified 15 clinical practice guidelines for the management of low back pain in primary care. For diagnosis of patients with non-specific low back pain, the clinical practice guidelines recommend history taking and physical examination to identify red flags, neurological testing to identify radicular syndrome, use of imaging if serious pathology is suspected (but discourage routine use), and assessment of psychosocial factors. For treatment of patients with acute low back pain, the guidelines recommend reassurance on the favourable prognosis and advice on returning to normal activities, avoiding bed rest, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and weak opioids for short periods. For treatment of patients with chronic low back pain, the guidelines recommend the use of NSAIDs and antidepressants, exercise therapy, and psychosocial interventions. In addition, referral to a specialist is recommended in case of suspicion of specific pathologies or radiculopathy or if there is no improvement after 4 weeks. While there were a few discrepancies across the current clinical practice guidelines, a substantial proportion of recommendations was consistently endorsed. In the current review, we identified some differences compared to the previous overview regarding the recommendations for assessment of psychosocial factors, the use of some medications (e.g., paracetamol) as well as an increasing amount of information regarding the types of exercise, mode of delivery, acupuncture, herbal medicines, and invasive treatments. These slides can be retrieved under Electronic Supplementary Material.

Measurement properties of the Brazilian version of the Working Alliance Inventory (patient and therapist short-forms) and Session Rating Scale for low back pain

BACKGROUND

In the low back pain (LBP) field, therapeutic alliance is considered a non-specific factor of interventions associated with improvements in clinical outcomes. However, there is a paucity of studies aimed to evaluate measurement properties of tools used to objectively quantify the alliance between therapist and patients, such as the Working Alliance Inventory (WAI) and Session Rating Scale (SRS).

OBJECTIVE

To translate and cross-culturally adapt the short-form version of WAI - therapist and SRS into Brazilian Portuguese; to investigate the measurement properties, of the WAI-Patient, WAI-Therapist and SRS in patients with LBP and their physical therapists, respectively.

METHODS

One hundred patients with LBP and 18 physical therapists were recruited from physical therapy clinics in Brazil. Therapeutic alliance measures were collected at the initial assessment, prior to the second session, and at 2-month follow-up. The measurement properties investigated were reproducibility, internal consistency, ceiling/floor effects and responsiveness.

RESULTS

Although WAI-Patient, WAI-Therapist and SRS were considered to have acceptable test-retest reliability (ICC2,1 > 0.70), these questionnaires showed problems with other measurement properties. WAI-Patient showed problems with internal consistency (i.e. Cronbach's alpha < 0.70 for all subscales). Presence of ceiling effect (i.e. > 15% of participants with the maximum score) and poor internal responsiveness were found for the WAI-Patient (Effect size = 0.15; 84% CI: 0.04 to 0.29) and for the SRS (Effect size = 0.05; 84% CI: -0.22 to 0.11). The WAI-Therapist revealed slightly better measurement properties.

CONCLUSION

We identified psychometric limitations with most measurement properties of the WAI questionnaires and SRS. Future studies are needed to refine these tools.

The efficacy of a multimodal physical activity intervention with supervised exercises, health coaching and an activity monitor on physical activity levels of patients with chronic, nonspecific low back pain (Physical Activity for Back Pain (PAyBACK) trial): study protocol for a randomised controlled trial

Background

Physical activity plays an important role in the management of chronic low back pain (LBP). Engaging in an active lifestyle is associated with a better prognosis. Nevertheless, there is evidence to suggest that patients with chronic LBP are less likely to meet recommended physical activity levels. Furthermore, while exercise therapy has been endorsed by recent clinical practice guidelines, evidence from systematic reviews suggests that its effect on pain and disability are at best moderate and not sustained over time. A limitation of current exercises programmes for chronic LBP is that these programmes are not designed to change patients’ behaviour toward an active lifestyle. Therefore, we will investigate the short- and long-term efficacy of a multimodal intervention, consisting of supervised exercises, health coaching and use of an activity monitor (i.e. Fitbit Flex) compared to supervised exercises plus sham coaching and a sham activity monitor on physical activity levels, pain intensity and disability, in patients with chronic, nonspecific LBP.

Methods

This study will be a two-group, single-blind, randomised controlled trial. One hundred and sixty adults with chronic, nonspecific LBP will be recruited. Participants allocated to both groups will receive a group exercise programme. In addition, the intervention group will receive health coaching sessions (i.e. assisting the participants to achieve their physical activity goals) and an activity monitor (i.e. Fitbit Flex). The participants allocated to the control group will receive sham health coaching (i.e. encouraged to talk about their LBP or other problems, but without any therapeutic advice from the physiotherapist) and a sham activity monitor. Outcome measures will be assessed at baseline and at 3, 6 and 12 months post randomisation. The primary outcomes will be physical activity, measured objectively with an accelerometer, as well as pain intensity and disability at 3 months post randomisation. Secondary outcomes will be physical activity, pain intensity and disability at 6 and 12 months post randomisation as well as other self-report measures of physical activity and sedentary behaviour, depression, quality of life, pain self-efficacy and weight-related outcomes at 3, 6, and 12 months post randomisation.

Discussion

This study is significant as it will be the first study to investigate whether a multimodal intervention designed to increase physical activity levels reduces pain and disability, and increases physical activity levels compared to a control intervention in patients with chronic LBP.

Physical Activity Interventions for Increasing Objectively Measured Physical Activity Levels in Patients With Chronic Musculoskeletal Pain: A Systematic Review

OBJECTIVE

To investigate whether physical activity interventions increase objectively measured physical activity levels of patients with chronic musculoskeletal pain (e.g., osteoarthritis, low back pain) compared to no/minimal intervention.

METHODS

We performed a systematic review with meta-analysis searching the Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, SportDiscus, and Physiotherapy Evidence Database (PEDro) databases, and the main clinical trials registries. Quasirandomized or randomized controlled trials investigating the effect of physical activity interventions on objectively measured physical activity levels (e.g., using accelerometers or pedometers) of patients with chronic musculoskeletal pain compared with no/minimal intervention were considered eligible. Analyses were conducted separately for short-term (≤3 months), intermediate (>3 months and <12 months), and long-term (≥12 months) followups. Pooled effects were calculated using the standardized mean difference (SMD), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used in summary conclusions.

RESULTS

Eight published trials and 6 registered trials were included. For the short-term followup, pooling of 6 trials showed no significant effect (SMD 0.34, 95% confidence interval -0.09, 0.77) between a physical activity intervention and no/minimal intervention. Similarly nonsignificant results were found for the intermediate and long-term followups. The overall evidence according to the GRADE approach was classified as low quality.

CONCLUSION

Our findings suggest that physical activity-based interventions may lead to little or no difference in objectively measured physical activity levels of patients with chronic musculoskeletal pain compared with no/minimal interventions. Given the number of registered trials, the pooled effect found in this review is likely to change once the results of these trials become available.

Aquatic Exercise for the Treatment of Hip and Knee Osteoarthritis

<LEAP> highlights the findings and application of Cochrane reviews and other evidence pertinent to the practice of physical therapy. The Cochrane library is a respected source of reliable evidence related to health care. Cochrane systematic reviews explore the evidence for and against the effectiveness and appropriateness of interventions-medications, surgery, education, nutrition, exercise-and the evidence for and against the use of diagnostic tests for specific conditions. Cochrane reviews are designed to facilitate the decisions of clinicians, patients, and others in health care by providing a careful review and interpretation of research studies published in the scientific literature. Each article in this PTJ series summarizes a Cochrane review or other scientific evidence on a single topic and presents clinical scenarios based on real patients or programs to illustrate how the results of the review can be used to directly inform clinical decisions. This article focuses on an older adult with severe knee joint pain. Can aquatic exercise help this patient with knee osteoarthritis?

Back and neck pain prevalence and their association with physical inactivity domains in adolescents

PURPOSE

Back pain affects people of all ages. This may be associated with physical inactivity, and in the case of physical activity in different domains, the relationship with back pain is not clear in the literature. The aim of this study was to estimate the prevalence of low back and neck pain and investigate their association in different domains of physical inactivity.

METHODS

1011 randomly selected students participated in this study. Neck and back pain were assessed using the Nordic questionnaire, whereas the Baecke Physical Activity questionnaire was used to measure physical activity domains. Separate Binary Logistic Regression models were performed to investigate the association of physical activity domains with neck or back pain.

RESULTS

17.4% of the students reported cervical pain, while 18.0% reported low back pain. Older adolescents had a higher prevalence of cervical pain (24.4%) than younger adolescents (11.9%) (p value <0.001), as well as lumbar pain, being 25.1% in older adolescents and 12.4% in younger (p value <0.001). Adolescents physically inactive in the school environment were less likely to have pain in the cervical region [OR 0.67 (0.44-0.99)] or back pain [OR 0.60 (0.40-0.91)]. Being inactive in occupational activities was associated with cervical pain [OR 1.49 (1.06-2.10)]. Being inactive in the sports environment presented a marginal relationship with pain in the cervical region [OR 1.41 (0.99-2.02)].

CONCLUSIONS

The prevalence of neck and low back pain was higher in older adolescents and physical inactivity in the sporting context and occupational activities could be a risk factor to increase the chances of back pain.

Effectiveness of Senior Dance on risk factors for falls in older adults (DanSE): a study protocol for a randomised controlled trial

INTRODUCTION

Strong evidence shows that exercise is effective to improve fall risk factors among older people. However, older people's participation and adherence to exercise programmes is suboptimal. Type of exercise and apathy are reported to be barriers to exercise participation, suggesting that new effective interventions are needed. The primary aim of this randomised controlled trial is to investigate the effect of Senior Dance plus brief education for falls prevention on balance among people aged 60 years or over, compared with a control group receiving only brief education.

METHODS AND ANALYSIS

This single-blind randomised controlled trial will involve 82 community-dwelling older people aged 60 years or over who are cognitively intact. Participants allocated to the intervention group will attend a single educational class on strategies to prevent falls, and will participate in a 12-week, twice-weekly group-based programme of Senior Dance. The Senior Dance consists of different choreographies, which include rhythmic and simple movements with rhythmic folk songs. Participants allocated to the control group will attend the same educational class that intervention group participants will receive, and will be instructed not to take part in any regular exercise programme. The primary outcome will be single-leg stance with eyes closed. Secondary outcomes include: Short Physical Performance Battery, Falls Efficacy Scale, Trail Making Test and the Montreal Cognitive Assessment. Continuous outcomes will be reported using mean (SD) or median (IQR), depending on the distribution of the data. The linear regression approach to analysis of covariance will be used to compare the mean effect between groups. All patients will be included in the analyses following an intention-to-treat approach.

ETHICS AND DISSEMINATION

Ethics approval has been granted by the Human Ethics Committee of the São Paulo State University (CAAE 48665215.9.0000.5402). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at conferences.

Interventions to improve gross motor performance in children with neurodevelopmental disorders: a meta-analysis

BACKGROUND

Gross motor skills are fundamental to childhood development. The effectiveness of current physical therapy options for children with mild to moderate gross motor disorders is unknown. The aim of this study was to systematically review the literature to investigate the effectiveness of conservative interventions to improve gross motor performance in children with a range of neurodevelopmental disorders.

METHODS

A systematic review with meta-analysis was conducted. MEDLINE, EMBASE, AMED, CINAHL, PsycINFO, PEDro, Cochrane Collaboration, Google Scholar databases and clinical trial registries were searched. Published randomised controlled trials including children 3 to ≤18 years with (i) Developmental Coordination Disorder (DCD) or Cerebral Palsy (CP) (Gross Motor Function Classification System Level 1) or Developmental Delay or Minimal Acquired Brain Injury or Prematurity (<30 weeks gestational age) or Fetal Alcohol Spectrum Disorders; and (ii) receiving non-pharmacological or non-surgical interventions from a health professional and (iii) gross motor outcomes obtained using a standardised assessment tool. Meta-analysis was performed to determine the pooled effect of intervention on gross motor function. Methodological quality and strength of meta-analysis recommendations were evaluated using PEDro and the GRADE approach respectively.

RESULTS

Of 2513 papers, 9 met inclusion criteria including children with CP (n = 2) or DCD (n = 7) receiving 11 different interventions. Only two of 9 trials showed an effect for treatment. Using the least conservative trial outcomes a large beneficial effect of intervention was shown (SMD:-0.8; 95% CI:-1.1 to -0.5) with "very low quality" GRADE ratings. Using the most conservative trial outcomes there is no treatment effect (SMD:-0.1; 95% CI:-0.3 to 0.2) with "low quality" GRADE ratings. Study limitations included the small number and poor quality of the available trials.

CONCLUSION

Although we found that some interventions with a task-orientated framework can improve gross motor outcomes in children with DCD or CP, these findings are limited by the very low quality of the available evidence. High quality intervention trials are urgently needed.

Fear of Movement Is Not Associated With Objective and Subjective Physical Activity Levels in Chronic Nonspecific Low Back Pain

OBJECTIVES

To assess the association of physical activity measures, derived with an accelerometer and a self-reported questionnaire, with fear of movement in patients with chronic nonspecific low back pain (LBP) and to investigate the association between disability and fear of movement in this population.

DESIGN

Cross-sectional study.

SETTING

Outpatient physical therapy university clinics.

PARTICIPANTS

Patients (N=119) presenting with nonspecific LBP of >3 months' duration.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Physical activity levels measured objectively with an accelerometer (ie, counts per minute, time spent in moderate-to-vigorous and light physical activity per day, number of steps per day, and number of 10-minute bouts of moderate-to-vigorous physical activity per day) and subjectively with a self-reported questionnaire (Baecke Physical Activity Questionnaire); fear of movement (Tampa Scale of Kinesiophobia); pain (11-point numerical rating scale); disability (Roland Morris Disability Questionnaire); and depression (Beck Depression Inventory). The associations were examined with correlational, univariate, and multivariable linear regression analyses.

RESULTS

None of the objective physical activity measures were associated with fear of movement. The apparent association of self-reported physical activity levels with fear of movement (correlational analyses: r=-.18; P<.05; univariate regression analyses: β=-.04; 95% confidence interval [CI], -.07 to -.01; P=.04) was not confirmed in multivariable analyses. Fear of movement was consistently associated with disability in both correlational (r=.42; P<.01) and multivariable (β=.21; 95% CI, .11-.31; P<.001) analyses.

CONCLUSIONS

Our data support one aspect of the fear-avoidance model-that higher fear of movement is associated with more disability-but not the aspect of the model linking fear of movement with inactivity.

Development of the Brazilian Portuguese version of the Achilles Tendon Total Rupture Score (ATRS BrP): a cross-cultural adaptation with reliability and construct validity evaluation

Background

There is a need for a patient-relevant instrument to evaluate outcome after treatment in patients with a total Achilles tendon rupture. The purpose of this study was to undertake a cross-cultural adaptation of the Achilles Tendon Total Rupture Score (ATRS) into Brazilian Portuguese, determining the test-retest reliability and construct validity of the instrument.

Methods

A five-step approach was used in the cross-cultural adaptation process: initial translation (two bilingual Brazilian translators), synthesis of translation, back-translation (two native English language translators), consensus version and evaluation (expert committee), and testing phase. A total of 46 patients were recruited to evaluate the test-retest reproducibility and construct validity of the Brazilian Portuguese version of the ATRS. Test-retest reproducibility was performed by assessing each participant on two separate occasions. The construct validity was determined by the correlation index between the ATRS and the Orthopedic American Foot and Ankle Society (AOFAS) questionnaires.

Results

The final version of the Brazilian Portuguese ATRS had the same number of questions as the original ATRS. For the reliability analysis, an ICC_(2,1) of 0.93 (95 % CI: 0.88 to 0.96) with SEM of 1.56 points and MDC of 4.32 was observed, indicating excellent reliability. The construct validity showed excellent correlation with R = 0.76 (95 % CI: 0.52 to 0.89, P < 0.001).

Conclusion

The ATRS was successfully cross-culturally validated into Brazilian Portuguese. This version was a reliable and valid measure of function in patients who suffered complete rupture of the Achilles Tendon.

Prenatal Alcohol Exposure, FASD, and Child Behavior: A Meta-analysis

CONTEXT

Fetal alcohol spectrum disorders (FASD) and prenatal alcohol exposure (PAE) are associated with behavioral difficulties, although there are no published systematic reviews that summarize and critique the literature.

OBJECTIVE

To describe the behavioral characteristics of children with PAE and/or FASD, assessed using the Achenbach System of Empirically Based Assessments (ASEBA) for school-aged children with parent, teacher, and youth (self-report) forms.

DATA SOURCES

Electronic literature databases, reference lists, hand-searches.

STUDY SELECTION

peer-reviewed observational studies.

DATA EXTRACTION

Study appraisal and data extraction were undertaken by 2 independent assessors. Meta-analyses were performed for parent-rated Internalizing, Externalizing, and Total problems scales. All other ASEBA scales were summarized qualitatively.

RESULTS

Included were 23 articles; 16 were used in meta-analyses. Pooled results showed higher Total (mean difference 12.1, 95% confidence interval [95% CI] 7.7-16.5), Internalizing (6.3, 95% CI 3.1-9.5), and Externalizing problems scores (12.5, 95% CI 7.9-17.0) in FASD than No FASD; and greater odds of scoring in the "Clinical" range in FASD. Pooled results demonstrated higher problem scores in children with PAE (P > .05). Qualitative summaries of other scales from parents, teachers, and self-report show poorer behavior ratings in children with FASD and PAE on composite Problem and Competence scores and many Syndrome subscales.

LIMITATIONS

Findings were restricted to behaviors assessed using the ASEBA. The published literature was limited, often with only 1 study reporting on a particular scale.

CONCLUSIONS

Meta-analysis reveals that FASD and PAE are associated with problematic behavior in many, but not all domains. This clearly affects families, and should be considered in clinical practice by providers.
