Physiotherapists' awareness and use of red flags for the assessment of low back pain in Saudi Arabia.

BACKGROUND: Physiotherapists must identify potential red flags that may impede recovery and function in individuals with low back pain (LBP) or put them at risk. OBJECTIVES: This study aimed to (1) investigate physiotherapists' awareness and use of red flags for individuals with LBP in Saudi Arabia and (2) identify factors associated with their awareness and use of LBP red flags. METHODS: This cross-sectional study collected data using an anonymous online questionnaire (February-July 2023). It included physiotherapists working in private/public hospitals in Saudi Arabia. The questionnaire asked about the participants' characteristics, their awareness of LBP red flags, and their use of red flags for LBP assessment. RESULTS: A total of 643 participating physiotherapists (26.2 ± 3.8 years), 63.8% of whom were females, completed the survey. Most participants (94.4%) had adequate awareness of LBP red flags, and more than half (61%) had good utilization of red flags when assessing individuals with LBP. There was a positive correlation between the physiotherapists' awareness and use of LBP red flags. CONCLUSION: The majority of the participating physiotherapists in Saudi Arabia were aware of LBP red flags, and many reported to have good use of red flags in clinical practice when assessing and managing individuals with LBP.

Poor lumbar spine coordination in acute low back pain predicts persistent long-term pain and disability.

PURPOSE: Sitting balance on an unstable surface requires coordinated out-of-phase lumbar spine and provides sufficient challenge to expose quality of spine control. We investigated whether the quality of spine coordination to maintain balance in acute low back pain (LBP) predicts recovery at 6 months. METHODS: Participants in an acute LBP episode (n = 94) underwent assessment of sitting balance on an unstable surface. Seat, hip and spine (lower lumbar, lumbar, upper lumbar, thoracic) angular motion and force plate data were recorded. Coordination between the seat and hip/spine segments to maintain balance was quantified in the frequency domain to evaluate coordination (coherence) and relative timing (phase angle: in-phase [segments move together]; out-of-phase [segments move opposite]). Center of pressure (CoP) and upper thorax motion assessed overall balance performance. Hip and spine coordination with the seat were compared between those who did not recover (increased/unchanged pain/disability), partially recovered (reduced pain/disability) or recovered (no pain and disability) at 6 months. RESULTS: In both planes, coherence between the seat and lower lumbar spine was lower (and in-phase-unhelpful for balance) at baseline in those who did not recover than those who recovered. Coherence between the seat and hip was higher in partially recovered in both planes, suggesting compensation by the hip. LBP groups had equal overall balance performance (CoP, upper thorax motion), but non-recovery groups used a less optimal strategy that might have consequences for long-term spine health. CONCLUSION: These longitudinal data revealed that individuals with compromised contribution of the lumbar spine to the balance during unstable sitting during acute LBP are less likely to recover.

Trunk postural control during unstable sitting among individuals with and without low back pain: A systematic review with an individual participant data meta-analysis.

INTRODUCTION: Sitting on an unstable surface is a common paradigm to investigate trunk postural control among individuals with low back pain (LBP), by minimizing the influence lower extremities on balance control. Outcomes of many small studies are inconsistent (e.g., some find differences between groups while others do not), potentially due to confounding factors such as age, sex, body mass index [BMI], or clinical presentations. We conducted a systematic review with an individual participant data (IPD) meta-analysis to investigate whether trunk postural control differs between those with and without LBP, and whether the difference between groups is impacted by vision and potential confounding factors. METHODS: We completed this review according to PRISMA-IPD guidelines. The literature was screened (up to 7th September 2023) from five electronic databases: MEDLINE, CINAHL, Embase, Scopus, and Web of Science Core Collection. Outcome measures were extracted that describe unstable seat movements, specifically centre of pressure or seat angle. Our main analyses included: 1) a two-stage IPD meta-analysis to assess the difference between groups and their interaction with age, sex, BMI, and vision on trunk postural control; 2) and a two-stage IPD meta-regression to determine the effects of LBP clinical features (pain intensity, disability, pain catastrophizing, and fear-avoidance beliefs) on trunk postural control. RESULTS: Forty studies (1,821 participants) were included for the descriptive analysis and 24 studies (1,050 participants) were included for the IPD analysis. IPD meta-analyses revealed three main findings: (a) trunk postural control was worse (higher root mean square displacement [RMSdispl], range, and long-term diffusion; lower mean power frequency) among individuals with than without LBP; (b) trunk postural control deteriorated more (higher RMSdispl, short- and long-term diffusion) among individuals with than without LBP when vision was removed; and (c) older age and higher BMI had greater adverse impacts on trunk postural control (higher short-term diffusion; longer time and distance coordinates of the critical point) among individuals with than without LBP. IPD meta-regressions indicated no associations between the limited LBP clinical features that could be considered and trunk postural control. CONCLUSION: Trunk postural control appears to be inferior among individuals with LBP, which was indicated by increased seat movements and some evidence of trunk stiffening. These findings are likely explained by delayed or less accurate corrective responses. SYSTEMATIC REVIEW REGISTRATION: This review has been registered in PROSPERO (registration number: CRD42021124658).

Coordination of hip and spine in individuals with acute low back pain during unstable sitting.

BACKGROUND CONTEXT: Trunk postural control differs between individuals with and without chronic low back pain (LBP). Whether this corresponds to differences in hip/spine coordination during the early acute phase of LBP (ALBP) is unclear. PURPOSE: To compare hip/spine coordination in relation to seat movements between individuals with and without ALBP when balancing on an unstable seat and to identify coordination strategies to maintain balance using cluster analysis. STUDY DESIGN/SETTING: Cross-sectional observational study. PATIENT SAMPLE: ALBP (n=130) and pain-free (n=72) individuals. OUTCOME MEASURES: Frequency domain measures to evaluate hip/spine coordination (amplitude spectrum, phase angle, and coherence) and time-series measures to assess overall balance performance (center of pressure [CoP] reflecting the amount of seat movements, upper thorax motion as a surrogate for head motion). METHODS: Participants maintained balance while sitting on a seat fixed to a hemisphere. Seat, hip, and spine (lower lumbar, lumbar, upper lumbar, and thoracic) angular motion and force plate data were recorded. RESULTS: Overall, seat/CoP movements (amplitude spectrum and RMSdisplacement) were greater (in both planes) and sagittal coordination (coherence) between the hip or lower spine and seat movements was lower in ALBP than controls. Cluster analysis using coherence data revealed different coordination strategies to maintain balance. Separate clusters used a "lower lumbar strategy" and "hip strategy" in the sagittal plane, and a "lower and upper lumbar strategy" and "lower lumbar strategy" in the frontal plane. A cluster using a "low coherence strategy" in both planes was also identified. CONCLUSIONS: Hip and lower spine coordination was less in individuals with ALBP in conjunction with a lower quality of overall balance performance. However, interpretation of the relationship between coherence and overall balance performance was not straightforward. Clusters in both the ALBP group and the control group adopted a low coherence strategy, and this was not consistently related to poor overall balance performance. This suggests overall balance performance cannot be inferred from coherence alone and requires consideration of interaction of other different features.

Investigating behavior, attitudes, knowledge, awareness and barriers to the implementation of evidence-based practice by physiotherapists in Egypt: A cross sectional study.

Few studies exist regarding the attitudes and behaviours of Egyptian physiotherapists in relation to the use of evidence in practice (EBP). The purpose of this study was to describe the beliefs, attitudes, knowledge, and behaviours of Egyptian physical therapists as they relate to evidence-based practice. It also explores their perception of possible barriers to implement EBP. Four hundred and seventy Egyptian therapists responded to our questionnaire with results revealing participants' awareness towards EBP was quite diverse. Only terms of systematic review and randomized controlled trial were well understood while remaining terms showed various level of comprehension which were rather low. Results also revealed significant correlations between attitudes towards EBP and overall awareness as well as attitudes and knowledge (r = 0.270 and 0.107) respectively. In addition, a significant relationship was also found between EBP awareness and knowledge with (r = 0.219). With regards to the barriers, insufficient teaching in previous education was identified as the primary barrier (34.4 %), followed by lack of funding and resources (31.1 %), while lack of time (10.2 %) was reported as the least. These barriers highlight the need to enhance implementation of EBP within Egyptian Physiotherapists. Findings of this study can be used as a foundation for the implementation of EBP in various clinical settings by understanding the limitations and barriers reported. Our study concluded that despite Egyptian physiotherapists declare their awareness of EBP, nevertheless, knowledge is restricted to a small number of terms. More focus is required to enhance the knowledge and practice of EBP. Focusing on adjustable factors, including increasing the awareness of value of research would help reduce time and resource demands for physiotherapists when implementing EBP.

Burden of musculoskeletal disorders in the gulf cooperation council countries, 1990-2019: Findings from the global burden of disease study 2019.

Objective: The purpose of this study was to investigate the burden of musculoskeletal (MSK) health conditions in Gulf Cooperation Council (GCC) countries based on the Global Burden of Disease (GBD) data. Methods: The data for GCC countries were obtained from the 2019 GBD study to evaluate the burden of MSK disorders which include the following countries: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates (UAE). The main outcome measures were age-standardized prevalence and years of life lived with disability (YLDs) associated with MSK disorders. The burden of MSK disorders attributable to the category of behavioral, metabolic, or environmental/occupational was reported to estimate the risk-attributable fractions of disease. Results: MSK disorders prevalence ranked fifth in Kuwait, sixth in Bahrain, Oman, Qatar, and UAE, and seventh in Saudi Arabia among all the diseases in 2019. For all GCC countries, MSK disorders were ranked the second leading cause of disability as measured by YLDs for the years 1990 and 2019. The age-standardized prevalence of MSK disorders in 2019 for Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and UAE was 18.56% (95% UI: 17.51­19.66), 19.35% (18.25­20.52), 18.23% (17.14­19.36), 18.93% (17.81­20.06), 19.05% (17.96­20.22), and 18.26% (17.18­19.38), respectively. The age-standardized YLDs per 100,000 individuals of MSK disorders in 2019 for Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and UAE were 1,734 (1,250­2,285), 1,764 (1,272­2,322), 1,710 (1,224­2,256), 1,721 (1,246­2,274), 1,715 (1,230­2,274), and 1,681 (1,207­2,235), respectively. For risk factors, high body mass index (BMI) had the highest contribution to MSK disorders YLDs in most GCC countries (Bahrain, Kuwait, Oman, and Saudi Arabia), followed by the exposure to occupational ergonomic factors which had the highest contribution to MSK disorders YLDs in Qatar and UAE. Conclusion: There was an increase in both age-standardized prevalence of MSK disorders and YLDs between 1990 and 2019 that was observed for all GCC countries. Some risk factors such as higher BMI and exposure to occupational ergonomic factors were highly associated with YLDs due to MSK disorders. The results of this study provide guidance for the potential nature of preventative and management programs to optimize the individual's health.

Postural control of the trunk in individuals with and without low back pain during unstable sitting: A protocol for a systematic review with an individual participant data meta-analysis.

INTRODUCTION: Postural control of the trunk is critical for performance of everyday activities and the health of spinal tissues. Although some studies report that individuals with low back pain (LBP) have poorer/compromised postural control than pain-free individuals when sitting on an unstable surface, others do not. Analyses commonly lack the statistical power to evaluate the relevance of features that could impact the performance of postural control, such as sex, age, anthropometrics, pain intensity or disability. This paper outlines a protocol for a systematic review with an individual participant data (IPD) meta-analysis that aims to synthesise the evidence and evaluate differences of postural control measures between individuals with and without LBP during unstable sitting. METHODS AND ANALYSIS: A systematic review with IPD meta-analysis will be conducted according to PRISMA-IPD guidelines. To identify relevant studies, electronic databases and the reference lists of included articles will be screened. Unstable seat movements are derived from centre of pressure (CoP) data using a force plate or angle of the seat using motion systems/sensors. The comprehensiveness of reporting and methodological quality of included studies will be assessed. Analysis will involve a descriptive analysis to synthesise the findings of all included studies and a quantitative synthesis using two-stage IPD meta-analysis of studies that include both individuals with and without LBP for which IPD set can be obtained from authors. Analyses will include consideration of confounding variables. ETHICS: Exemption from ethical approval was obtained for this review (University of Queensland, ID: 2019003026).

Balance control in unstable sitting in individuals with an acute episode of low back pain.

BACKGROUND: Low back pain (LBP) is associated with altered postural control, mostly observed at later stages in the LBP trajectory. It is unclear whether postural control differs in the acute phase of LBP. RESEARCH QUESTION: Is postural control different in the acute phase of LBP (<2 weeks) and do differences depend on pain intensity, psychological features and/or availability of vision to control posture? METHODS: Cross-sectional study design. An unstable sitting paradigm (to reduce the contribution of the legs) assessed postural control of participants with acute LBP (n = 133) and pain-free controls (n = 74). Centre of pressure (CoP) reflected seat movements. Participants balanced with eyes closed, open, or with visual feedback of the anteroposterior CoP position. Balance performance was expressed by CoP displacement and velocity, and stabilogram diffusion analysis. Generalised estimating equations (GEEs) including body mass index, sex, and safety bar touch, tested differences between groups and between balance conditions. Separate GEEs were used to model performance measures and bar touch (yes/no) including pain intensity, disability and psychological features. RESULTS: CoP displacement and critical point coordinates (time and distance where CoP diffusion rate or spread slows) were larger in LBP than pain-free controls independent of balance condition. Long-term diffusion rate was greater in LBP than controls with eyes closed. CoP velocity measures (RMS, short term diffusion rate) were not different between groups. Pain intensity and psychological features were not linearly related to balance performance in participants with acute LBP. Higher pain catastrophizing was associated with touching the safety bar. SIGNIFICANCE: Postural control differs in acute LBP than pain-free controls. Findings might be explained by altered sensory processing, lesser ability to reweight proprioceptive information and/or less accurate trunk muscle control. Although not linearly related to pain-intensity or psychological features in the acute stage, reduced balance performance could potentially have impact on LBP recovery.

The association between sedentary behavior and low back pain in adults: a systematic review and meta-analysis of longitudinal studies.

Background: Low back pain (LBP) is a common musculoskeletal problem globally. While spending a longer time in sedentary behaviors is linked to several health problems; the quantitative association between different amounts of sedentary time and LBP is still unknown. This study aims to systematically review studies that examined the association between sedentary behavior and LBP development and LBP-related outcomes. Methods: This systematic review and meta-analysis retrieved journal articles published from inception to March 2020 and were obtained by searching bibliographical databases. We included longitudinal study designs, including adult (aged ≥18) individuals with nonspecific LBP, and reporting estimates of the association between sedentary behavior and LBP development and LBP-related outcomes (i.e., pain intensity and disability). Results: Sixteen longitudinal studies with 100,002 participants were included in this review (eight studies included in quantitative syntheses with 83,111 participants). The results of meta-analyses showed that a sedentary time of 3-<6 (Odds ratio (OR) 0.95, 95% CI [0.85-1.07]), 6-8 (OR 0.95, 95% CI [0.88-1.02]), and >8 (OR 0.92, 95% CI [0.85-1.00]) hours per day (h/d) was not associated with LBP development. A sedentary time of ≥3 h/d was associated with poor LBP-related disability (OR 1.24, 95% CI [1.02-1.51]), but not with pain intensity. Conclusion: A meta-analyses of longitudinal studies indicated that sedentary behavior of different durations was not associated with LBP development. However, the results showed that sedentary behavior ≥3 h/d was associated with worse LBP-related disability. These conclusions are tentative as the evidence was derived from mostly fair-quality studies using subjective measures of sedentary behavior.

The Effect of Robot-Mediated Virtual Reality Gaming on Upper Limb Spasticity Poststroke: A Randomized-Controlled Trial.

Objective: Stroke is a common reason for motor disability and is often associated with spasticity and poor motor function of the upper limbs involved. Spasticity management is important to accelerate motor recovery. The objective of this study was to investigate the effects of training with robot-mediated virtual reality gaming on upper limb spasticity and motor functions in individuals with chronic stroke. Materials and Methods: A total of 40 Saudi individuals with chronic stroke were involved in this study. Participants were randomly assigned to two groups. The experimental group received conventional physiotherapy and training with robot-mediated virtual reality gaming, and the control group received only conventional physiotherapy. Outcomes were measured by the Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), WMFT-Time, Modified Ashworth Scale (MAS), Active Range of Motion (AROM) of multiple joints of the upper limb, and Handgrip Strength (HGS). The scores of all the outcome measures were recorded at baseline and after the completion of the treatment. Results: Individuals with stroke in the experimental group had a better improvement in most measured variables (AROM of shoulder abduction, elbow supination and wrist extension, WMFT-Time, HGS, ARAT, WMFT, and MAS) compared with the control group after the completion of the treatment. Both groups showed significant improvement in all the measured variables after completion of the treatment, except in MAS for wrist flexors in the control group. Conclusion: Training with robot-mediated virtual reality gaming was effective in modulating spasticity and improving the motor functions of the affected upper limbs in individuals with chronic stroke. This study was registered in ClinicalTrial.gov (NCT05069480).

The Effect of Virtual Reality-Based Therapy on Improving Upper Limb Functions in Individuals With Stroke: A Randomized Control Trial.

Background: Stroke is a common cause of motor disability. The recovery of upper limb after stroke is poor, with few stroke survivors regaining some functional use of the affected upper limb. This is further complicated by the fact that the prolonged rehabilitation is accompanied by multiple challenges in using and identifying meaningful and motivated treatment tasks that may be adapted and graded to facilitate the rehabilitation program. Virtual reality-based therapy is one of the most innovative approaches in rehabilitation technology and virtual reality systems can provide enhanced feedback to promote motor learning in individuals with neurological or musculoskeletal diseases. Purpose: This study investigated the effect of virtual reality-based therapy on improving upper limb functions in individuals with chronic stroke. Methods: Forty Saudi individuals with chronic stroke (6-24 months following stroke incidence) and degree of spasticity ranged between 1, 1 + and 2 according to Modified Ashworth Scale were included in this study. Participants were randomly assigned into two groups, experimental and control, with the experimental group undertaking a conventional 1-h functional training program, followed by another hour of virtual reality-based therapy using Armeo Spring equipment and the control group received 2 h of a conventional functional training program. The treatment program was conducted three times per week for three successive months. The change in the scores of Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), WMFT-Time (time required to complete the test) and Hand Grip Strength (HGS) were recorded at baseline and after completion of the treatment. Parametric (paired and unpaired t-tests) non-parametric (Wilcoxon and Mann-Whitney tests) statistical tests were used to identify the differences within and between groups (experimental group and control group) and evaluation times (pre- and immediately post-treatment). Results: Both groups showed significant differences (all, P < 0.05) in all measured variables after 3 months of the treatment. Individuals with stoke in the experimental group had a better improvement in ARAT (P < 0.01), WMFT (P < 0.01) and WMFT-Time (P < 0.01) scores after completion of the treatment compared to the control group. No significant difference in HGS scores was detected between groups after completion of the treatment (P = 0.252). Conclusion: The use of combined treatment of virtual reality-based therapy and conventional functional training program is more effective for improving upper limb functions in individuals with chronic stroke than the use of the conventional program alone.

Coordination of hip and spine to maintain equilibrium in unstable sitting revealed by spectral analysis.

Unstable sitting paradigms have been used to assess the trunk's contribution to postural control. The coordination of spine or hip with an unstable seat that underpin postural control during this task remain unclear. This study aimed to address this issue using analysis in the frequency domain. Seventy-two healthy pain-free participants maintained balance while sitting on a seat fixed to a hemisphere. Angular motion of seat, spinal regions (lower lumber, lumbar, upper lumbar, and thoracic), and hip was recorded with a three-dimensional (3-D) motion capture system. Coordination between spinal regions and hip with the seat was quantified using cross-spectral analyses. In the sagittal plane, amplitude spectrum of hip and lumbar segments were higher than other segments, coherence between these segments and the seat was high, and their motion was generally opposite in direction to the seat. In the frontal plane, amplitude spectrum of lower lumbar and lumbar segments, but not the hip, were higher than other segments, and coherently moved in the opposite direction to the seat. Segments closest to the seat made a direction-specific and greater contribution to maintenance of equilibrium than upper body segments, which were more limited during unstable sitting. Although eye closure and higher body mass index involved larger amplitude of center of pressure movement, rather than inferring poor control, this was associated with enhanced coordination between segments and seat. Understanding how hip/spine segments are coordinated with the seat is important to interpret postural strategies used to maintain equilibrium and to interpret observations for other populations (e.g., back pain).NEW & NOTEWORTHY This is the first multidirectional spectral analysis of how the hip and spine coordinate during unstable sitting and how different factors impact this coordination. Seat movement was coherently counteracted (out-of-phase) by angular motion of the hip and lower lumbar spine in the sagittal plane and by the lumbar spine in the frontal plane. Although higher BMI and balancing with eyes closed increased movement amplitude, this did not compromise coordination between segments to control balance, instead, coherence increased.

Effects of Interactive Videogames on Postural Control and Risk of Fall Outcomes in Frail and Pre-frail Older Adults: A Systematic Review and Meta-Analysis.

Background: Interactive videogames (IVGs) have been used to reduce risk of falls in the older adult and improve postural control (PC) outcomes. Objective: To systematically review trials that examine whether IVGs training is effective in improving PC and managing falls in frail and pre-frail older adults. Data Sources: Four databases were searched, Scopus, Web of science, PubMed, and MEDLINE, from January 2007 to March 2019. Eligibility Criteria: Frail and pre-frail older adults aged 65+. Interventions were any Nintendo® Wii™ training. The outcome measures were PC and risk of falls as measured by any validated outcome measure. Studies Appraisal Method: The PEDro (Physiotherapy Evidence Database) scale and Cochrane risk-of-bias tool were used by two independent authors. Results: Eleven papers were included, involving 388 participants, with a mean age of 79 ± 5.7 years. The mean duration of IVGs sessions was 8.8 ± 3.8 weeks, the mean total number of sessions was 20 ± 11.1 session, and the mean length of training was 44 ± 15.7 minutes. Meta-Analysis: IVGs achieved better results compared with traditional exercises and control on the Berg Balance Scale (mean difference [MD] 2.80; 95% confidence interval [CI] 1.21 to 4.39; P < 0.001; I2 = 16%), as well as in the short term on Timed Up and Go (MD -1.23; 95% CI -2.37 to -0.09; P = 0.03; I2 = 0%). Limitation: Definitive judgement could not be made due to the variability in training, training duration and outcomes measurement. Conclusion: IVGs is a promising modality that has a positive effect on PC but not on the outcome of falls, so it should be prescribed with caution among frail older adults.

The Prevalence and Factors Associated with Musculoskeletal Pain Among Pilgrims During the Hajj.

BACKGROUND: Musculoskeletal pain is a primary burden on individuals as well as social and health care systems. Annually, 2-3 million pilgrims perform the Hajj in Mecca, Saudi Arabia. The Hajj is highly physically demanding because pilgrims generally move by foot for long distances among a series of religious sites, an effort that may exceed their typical levels of physical activity. To understand the impact of musculoskeletal pain on the completion of the Hajj, it is first necessary to evaluate the extent of the problem. Accordingly, this study aimed to estimate the prevalence of musculoskeletal pain and associated factors among pilgrims during the Hajj. METHODS: A cross-sectional survey was conducted during the period of the Hajj. The participants were adult pilgrims ≥ 18 years of age. Data regarding demographics, the prevalence of falls and the point prevalence of musculoskeletal pain by anatomical site were recorded. Participants were allowed to report more than one site of pain. Prevalence, crude and adjusted risk ratios were calculated. RESULTS: A total of 1715 pilgrims were included in the analysis. The prevalence of falls was 13.76%. The prevalence of overall musculoskeletal pain (pain at any site) was 80.46%. Musculoskeletal pain was most commonly reported in the ankle/foot (38.34%), leg (29.89%), lower back (28.47%) and knee (21.84%). In general, musculoskeletal pain at multiple sites was more common in females and in older and obese individuals. However, there were variations in the importance of sex, age and body mass index as associated factors across different pain sites. CONCLUSION: Musculoskeletal pain is common among pilgrims. Unlike most populations examined in other studies, ankle/foot pain was the most common in pilgrims. These data provide guidance for potential preventative programs and the allocation of resources to optimize pilgrims' experiences and ability to complete the Hajj.

Psychosocial Predictors of Pain and Disability Outcomes in People with Chronic Low Back Pain Treated Conservatively by Guideline-Based Intervention: A Systematic Review.

OBJECTIVE: Previous evidence has recommended conservative interventions as the best treatment in individuals with chronic low back pain (CLBP). However, the influence of psychosocial factors on the treatment outcomes is unclear. Therefore, this systematic review aimed to address the psychosocial factors that influence changes in pain and disability in patients with CLBP after a guideline-based conservative intervention. METHODS: Four electronic databases were systematically searched from inception until September 2020 for prospective studies examining the relationship between psychosocial factors and the outcomes of pain and disability after conservative intervention. All included studies were selected, extracted, and critically evaluated by two independent reviewers. RESULTS: In total, 15 studies were included in this systematic review. The results support the link between the baseline fear of movement, depression, self-efficacy, and catastrophizing with future functional disability outcomes after conservative interventions. However, these factors were less likely to predict changes in pain intensity outcomes after conservative interventions. Self-efficacy seems to mediate between some of the baseline psychosocial factors (eg, fear) and future pain and disability. CONCLUSION: Fear of movement, self-efficacy, catastrophizing and depression were consistently reported to predict disability outcomes irrespective of the type of conservative intervention. This highlights the importance of addressing these factors in conservative management of CLBP.

Inter-rater reliability of physiotherapists using the Action Research Arm Test in chronic stroke.

OBJECTIVES: The purpose of this study is to establish whether physiotherapists' ratings are consistent, when using the Action Research Arm Test (ARAT) to score a chronic stroke patient. METHODS: This was part of a large project establishing the reliability in chronic stroke. This study used a correlational design comparing the association between physiotherapist scores of the same patient, to establish the ARAT's inter-rater reliability. The COSMIN checklist was followed to enhance the methodology of the study. RESULTS: Twenty physiotherapists (8 female and 12 male) aged between 25 and 53 years were selected. There were no participant dropouts or withdrawals. The sample size was normally distributed. The physiotherapists appeared representative of the UK physiotherapy population, with the exception of gender. The distribution of scores showed a normal distribution with standard deviation of score of 1.9. The Kendall's W test showed 0.711 of agreement between the raters. The scores achieved statistical significance showing consistency between physiotherapists' scores with chronic stroke. Limitations of the study were the use of a small single center convenience sample that may reduce the generalizability of the findings. CONCLUSIONS: The ARAT is consistent when scored by physiotherapists in a chronic stroke population. The inter-rater reliability range was (0.70 to 0.90) which is categorized as good.

Neurological and Musculoskeletal Features of COVID-19: A Systematic Review and Meta-Analysis.

Importance: Some of the symptoms of COVID-19 are fever, cough, and breathing difficulty. However, the mechanism of the disease, including some of the symptoms such as the neurological and musculoskeletal symptoms, is still poorly understood. Objective: The aim of this review is to summarize the evidence on the neurological and musculoskeletal symptoms of the disease. This may help with early diagnosis, prevention of disease spread, and treatment planning. Data Sources: MEDLINE, EMBASE, Web of Science, and Google Scholar (first 100 hits) were searched until April 17, 2020. The key search terms used were "coronavirus" and "signs and symptoms." Only studies written in English were included. Study Selection: The selection was performed by two independent reviewers using EndNote and Rayyan software. Any disagreement was resolved by consensus or by a third reviewer. Data Extraction and Synthesis: PRISMA guidelines were followed for abstracting data and assessing the quality of the studies. These were carried out by two and three independent reviewers, respectively. Any disagreement was resolved by consensus or by a third reviewer. The data were analyzed using qualitative synthesis and pooled using a random-effect model. Main Outcome(s) and Measure(s): The outcomes in the study include country, study design, participant details (sex, age, sample size), and neurological and musculoskeletal features. Result: Sixty studies (n = 11, 069) were included in the review, and 51 studies were used in the meta-analysis. The median or mean age ranged from 24 to 95 years. The prevalence of neurological and musculoskeletal manifestations was 35% for smell impairment (95% CI 0-94%; I 2 99.63%), 33% for taste impairment (95% CI 0-91%; I 2 99.58%), 19% for myalgia (95% CI 16-23; I 2 95%), 12% for headache (95% CI 9-15; I 2 93.12%), 10% for back pain (95% CI 1-23%; I 2 80.20%), 10% for dizziness (95% CI 3-19%; I 2 86.74%), 3% for acute cerebrovascular disease (95% CI 1-5%; I 2 0%), and 2% for impaired consciousness (95% CI 1-2%; I 2 0%). Conclusion and Relevance: Patients with COVID-19 present with neurological and musculoskeletal symptoms. Therefore, clinicians need to be vigilant in the diagnosis and treatment of these patients.

Physiotherapists' pain attitudes and beliefs towards chronic low back pain and their association with treatment selection: a cross-sectional study.

OBJECTIVES: The main aim of this study was to investigate physiotherapists' pain attitudes and beliefs towardss non-specific chronic low back pain (NSCLBP) and identify whether they are associated with treatment selection. DESIGN: Cross-sectional study. SETTING: Saudi Arabia (SA). PARTICIPANTS: An online survey was distributed to physiotherapists from April 2018 to January 2019. PRIMARY AND SECONDARY OUTCOME MEASURES: (1) Biomedical and biopsychosocial treatment orientations were assessed using the Pain Attitudes and Beliefs Scale for Physiotherapists. (2) Frequent potential treatments used by physiotherapists for individuals with NSCLBP were identified through a 20-item survey. (3) The association between physiotherapists' pain attitudes and beliefs and treatment selection was investigated. Descriptive analysis, Pearson's correlation and multinomial logistic regression were used to analyse the data using SPSS (V.26). RESULTS: A total of 304 responses were included in the analysis. The biomedical (34.45±7.84) and biopsychosocial (31.74±5.67) treatment orientations were relatively low. The most frequent treatments used by physiotherapists were home exercises (87.1%), patient education (82.0%), specific back exercises (80.6%), electrotherapy (61.9%), soft tissue release (58.8%) and spinal mobilisation or manipulation (57.8%). Physiotherapists with a stronger biomedical treatment orientation were more likely to use treatments (p<0.05) such as specific back exercises, electrotherapy, soft tissue release, hydrotherapy, massage, lumbar supports and acupuncture. However, physiotherapists with a stronger biopsychosocial treatment orientation were more likely to use cognitive functional therapy (p<0.01). CONCLUSIONS: Biomedical and biopsychosocial treatment orientations were relatively low among physiotherapists in SA. Although treatments such as home exercises and patient education were frequently used, some passive and traditional treatments not recommended by clinical practice guidelines continue to be commonly used by physiotherapists in SA. This study has confirmed that physiotherapists' pain attitudes and beliefs are significantly associated with treatment selection when managing individuals with NSCLBP.

The effectiveness of McKenzie method compared to manual therapy for treating chronic low back pain: a systematic review.

The aim of this study was to evaluate the effectiveness of the McKenzie method compared to manual therapy in the management of patients with chronic low back pain (CLBP). Randomised controlled trials evaluating the McKenzie method in treating CLBP in adults compared to manual therapy (MT) were searched in MEDLINE, CINAHL, Cochrane Library, and PEDro. The primary outcomes were pain and disability. Five trials were eligible for inclusion in the review, of which, most had a score of 8 out of 11 on the PEDro scale. At 2-3 months, all studies reported significant improvement in the pain level in the McKenzie group, and more than that in the MT group. At 6 months, significant improvements had occurred in the disability index reported by two trials in the McKenzie group than the MT group. At 12 months follow-up, there were no significant differences in measures of LBP, but three studies reported that the McKenzie method group had a better disability level than the MT group. In patients with CLBP, many pain measures showed that the McKenzie method is a successful treatment to decrease pain in the short term, while the disability measures determined that the McKenzie method is better in enhancing function in the long term.
