Introduction: The objective of this study was to adapt the Brazilian version, and verify the validity, reliability and internal consistency of the Oliveira questionnaire on low back pain in young people.Material and Methods: The questionnaire was translated from European Portuguese into Brazilian Portuguese by means of translation and re-translation. The validity of the contents was determined by experts who analyzed the clarity and pertinence of the questions. Fifteen young people aged 15 to 18 took part in the pre-test step (qualitative analysis), 40 in the test-retest (reliability) and 679 in the evaluation of internal consistency. The intra-class correlation coefficient and Spearman’s correlation coefficient were used in the reliability analysis (test-retest), and Cronbach’s alpha to determine the internal consistency (stability).Results: In the translation phase the questionnaire was modified and considered suitable, observing similarity and equivalence of the two versions. After being corrected by the experts in the validation of the contents, the instrument was considered suitable and valid, and in the pre-test, the young people suggested some modifications to make the questionnaire more succinct. With respect to reliability, the values for the intra-class correlation coefficient were between 0.512 – acceptable and 1 – excellent and Spearman’s correlation coefficient varied between 0.525 and 1, classifying the instrument as reproducible. The internal consistency was considered acceptable with a 0.757 Cronbach’s alpha.Discussion: The Oliveira questionnaire was choosen since it has been used in several Portuguese studies; moreover, it addresses the need to raise data regarding low back pain and associated risk factors.Conclusions: The Brazilian version of the Oliveira questionnaire on low back pain in young people showed valid and reliable cultural adaptation, with good reliability and stability.

Real-time ultrasound imaging (US) to measure abdominal muscle dimensions has aided low back pain rehabilitation and research. Notwithstanding, ultrasound imaging measurement of transversus abdominis muscle activation in chronic low back pain populations has been characterized by variable and generally suboptimal intra-observer reliability. Methodological deficiencies of ‘freehand’ ultrasound imaging are uncontrolled probe–skin pressure, inclination and roll of the probe. Despite previous attempts to standardize these parameters, intra-observer reliability in chronic low back pain was poor to moderate (0.32–0.62). Therefore, a standardized method that controls and records probe force, inclination and roll during ultrasound imaging may optimize measurement reliability in chronic low back pain. This pilot study investigated utility, standardization and intra-observer reliability of ultrasound imaging transversus abdominis thickness measurement in chronic low back pain patients (n = 17). Transversus abdominis imaging over two separate measurement sessions was conducted using a novel method to standardize probe parameters. Resting and contracted transversus abdominis thickness, and transversus abdominis activation measurements were obtained from duplicate paired images (n = 68). Intra-class correlation coefficients were reported with 95% confidence intervals. Transversus abdominis thickness at rest (intra-class correlation coefficient = 0.97 confidence interval: 0.93, 0.99), when contracted (intra-class correlation coefficient = 0.99 confidence interval: 0.97, 0.99) and transversus abdominis activation (intra-class correlation coefficient = 0.93 confidence interval: 0.81, 0.97) measurements were highly reliable. Ultrasound imaging of transversus abdominis using the novel standardized ultrasound imaging method produced highly reliable intra-observer transversus abdominis measurements, superior to ‘freehand’ ultrasound imaging, despite the physical limitations typically associated with a chronic low back pain population. Unique standardizing ranges for ‘probe force device’ probe parameters were obtained. This novel standardized ultrasound imaging method may optimize transversus abdominis activation assessment in chronic low back pain and other populations, aiding future research.

Improvement in rider mobility represents an important functional gain for people with disabilities undergoing hippotherapy. However, there is no validated measuring instrument to track and document the rider's progress in riding activities. In this study, we aimed to develop and establish validity evidence for an instrument to assess hippotherapy participants’ mobility on horseback. We report on this development through the stages of: (a) content validation, (b) construct validation, (c) inter- and intra-rater reliability and (d) internal consistency analysis. We evaluated its factor structure with exploratory factor analyses, calculated values for inter- and intra-rater reliability using the intra-class correlation coefficient, and calculated its internal consistency using Cronbach's alpha. We followed recommendations by the Guidelines for Reporting Reliability and Agreement Studies. We found good inter-rater reliability (intra-class correlation coefficient – ICC = 0.991–0.999) and good intra-rater reliability (ICC = 0.997–1.0), and there was excellent internal consistency (Cronbach's α = 0.937–0.999). The instrument’s factor structure grouped its three domains into one factor. As this instrument is theoretically consistent and has been found to be appropriate and reliable for its intended use, it is now available for the measurement of horseback mobility among hippotherapy riders.

<b><i>Introduction:</i></b> This study reports on the translation, cultural adaptation, and validation of a Portuguese version of the Rotterdam Elderly Pain Observation Scale (REPOS), a Dutch scale to assess pain in patients who cannot communicate, with or without dementia. <b><i>Methods:</i></b> This is a multicenter study in pain and neurological units involving Brazil (clinical phase) and the Netherlands (training phase). We performed a retrospective cross-sectional, 2-staged analysis, translating and culturally adapting the REPOS to a Portuguese version (REPOS-P) and evaluating its psychometric properties. Eight health professionals were trained to observe patients with low back pain. REPOS consists of 10 behavioral items scored as present or absent after a 2-min observation. The REPOS score of ≥3 in combination with the Numerical Rating Scale (NRS) of ≥4 indicated pain. The Content Validity Index (CVI) in all items and instructions showed CVI values at their maximum. According to the higher correlation coefficient found between NRS and REPOS-P, it may be suggested that there was an adequate convergent validity. <b><i>Results:</i></b> The REPOS-P was administered to 80 patients with a mean age of 60 years (SD 11.5). Cronbach’s alpha coefficient showed a moderate internal consistency of REPOS-P (α = 0.62), which is compatible with the original study of REPOS. All health professionals reached high levels of interrater agreement within a median of 10 weeks of training, assuring reproducibility. Cohen’s kappa was 0.96 (SD 0.03), and the intraclass correlation coefficient was 0.98 (SD 0.02), showing high reliability of REPOS-P scores between the trainer (researcher) and the trainees (healthcare professionals). The Pearson correlation coefficient was 0.95 (95% confidence interval 0.94–0.97), showing a significant correlation between the total scores of REPOS-P and NRS. <b><i>Conclusion:</i></b> The REPOS-P was a valuable scale for assessing elderly patients with low back pain by different healthcare professionals. Short application time, ease of use, clear instructions, and the brief training required for application were essential characteristics of REPOS-P.

The purpose of this study was to adapt the Spitzer Quality of Life Index and evaluate its reliability in patients with low back pain. The following steps were followed: translation, back-translation, evaluation by a committee, and pretest. The reliability was estimated through stability and homogeneity assessment. The validity was tested comparing scores of the Spitzer (QLI) with the SF-36 and the Roland-Morris. The psychometric properties were evaluated by the self-application on 120 patients. Results showed that the Cronbach's Alpha was 0.77. Intraclass correlation coefficient for test-retest reliability was 0.960 (p<0.001; IC95%: 0.943; 0.972). Spearman´s correlation coefficient for test-retest reliability was 0.937 (p<0.001). There was significant correlation between the Spitzer (QLI) scores and the dimensions of the SF-36. A significant negative correlation was found between the Spitzer (QLI) and the Roland-Morris scores (r = - 0.730). The adaptation process was conducted successfully and the questionnaire presented reliable psychometric measures.

Background The Pain Self-Efficacy Questionnaire (PSEQ) is used by physical therapists in clinical practice and in research. However, current understanding of the PSEQ's measurement properties is incomplete, and investigators cannot be confident that it provides unbiased information on patient self-efficacy. Objective The aims of this study were: (1) to investigate the scale properties of the PSEQ using Rasch analysis and (2) to determine whether age, sex, pain intensity, pain duration, and pain-related disability bias function of the PSEQ. Design This was a retrospective study; data were obtained from 3 existing studies. Methods Data were combined from more than 600 patients with low back pain of varying duration. Rasch analysis was used to evaluate targeting, category ordering, unidimensionality, person fit, internal consistency, and item bias. Results There was evidence of adequate category ordering, unidimensionality, and internal consistency of the PSEQ. Importantly, there was no evidence of item bias. Limitations The PSEQ did not adequately target the sample; instead, it targeted people with lower self-efficacy than this population. Item 7 was hardest for participants to endorse, showing excessive positive misfit to the Rasch model. Response strings of misfitting persons revealed older participants and those reporting high levels of disability. Conclusions The individual items of the PSEQ can be validly summed to provide a score of self-efficacy that is robust to age, sex, pain intensity, pain duration, and disability. Although item 7 is the most problematic, it may provide important clinical information and requires further investigation before its exclusion. Although the PSEQ is commonly used with people with low back pain, of whom the sample in this study was representative, the results suggest it targets patients with lower self-efficacy than that observed in the current sample.

Introduction: The Exercise Self-Efficacy scale (ESES) is a reliable measure, in the English language, of exercise self-efficacy in individuals with spinal cord injury. The aim of this study was to culturally adjust and validate the Exercise Self-Efficacy scale in the Portuguese language.Material and Methods: The Exercise Self-Efficacy scale was applied to 76 subjects, with three-month intervals (three applications in total). The reliability was appraised using the intra-class correlation coefficient and Bland-Altman methods, and the internal consistency was evaluated using Cronbach´s alpha. The Exercise Self-Efficacy scale was correlated with the domains of the Quality of life Questionnaire SF-36 and Functional Independence Measure and tested using the Spearman rho coefficient.Results: The Exercise Self-Efficacy scale-Brazil presented good internal consistency (alpha 1 = 0.856; alpha 2 = 0.855; alpha 3 = 0.822) and high reliability in the test-retest (intra-class correlation coefficient = 0.97). There was a strong correlation between the Exercise Self-Efficacy scale-Brazil and the SF-36 only in the functional capacity domain (rho = 0.708). There were no changes in Exercise Self-Efficacy scale-Brazil scores between the three applications (p = 0.796).Discussion: The validation of the Exercise Self-Efficacy scale questionnaire permits the assessor to use it reliably in Portuguese speaking countries, since it is the first instrument measuring self-efficacy specifically during exercises in individuals with spinal cord injury. Furthermore, the questionnaire can be used as an instrument to verify the effectiveness of interventions that use exercise as an outcome.Conclusion: The results of the Brazilian version of the Exercise Self-Efficacy scale support its use as a reliable and valid measurement of exercise self-efficacy for this population.

Purpose – The purpose of this paper is to develop an expert system capable of assessing risk associated with manual lifting in construction tasks and proffer some first aid advices which are comparable with those obtainable from human experts. Design/methodology/approach – The expert system, musculoskeletal disorders – risk evaluation expert system (MSDs-REES), used Microsoft.Net C# programming language to write the algorithm of the fuzzy inference system with variables load, posture and frequency of lift as inputs and risk of low back pain as the output. The algorithm of the inference engine applied sets of rules to generate the output variable in crisp value. Findings – The result of validation, between the human experts’ calculated risk values and MSDs-REES-predicted risk values, indicated a correlation coefficient of 0.87. Between the predicted risk values generated using MSDs-REES and the existing package (MATLAB version 7.8), there was a strong positive relationship statistically with correlation coefficient of 0.97. Originality/value – The study provided a very simple expert system which has the ability to provide some medical-related injury prevention advice and first aid information for injury management, giving it a unique attribute over the existing applications.

Abstract Background: Catastrophizing has been recognized as an important contributor to chronicity in individuals with chronic pain syndromes including low back pain (LBP). The Pain Catastrophizing Scale (PCS) is perhaps the most widely used questionnaire to evaluate the degree of pain catastrophizing. However, its use is limited in Hausa-speaking countries due to the lack of a validated translated version.Objective: To translate and cross-culturally adapt the PCS into Hausa (Hausa-PCS) and evaluate its psychometric properties in mixed urban and rural patients with chronic LBP.Methods: The original PCS was translated and cross-culturally adapted into Hausa in accordance with established guidelines. To evaluate psychometric properties, a consecutive sample of 200 patients with chronic LBP was recruited from urban and rural Nigerian hospitals. Validity was evaluated by exploring content validity (skewness and item-total correlation), factorial structure (exploratory factor analysis [EFA] and confirmatory factor analysis [CFA]), concurrent validity (Spearman’s rho) and known-groups validity. Reliability was evaluated by calculating internal consistency (Cronbach’s α), intraclass correlation coefficient (ICC), standard error of measurement (SEM), minimal detectable change (MDC) and limits of agreement with 95% confidence interval (LOA95%).Results: The Hausa-PCS demonstrated good face and content validity. Both EFA and CFA confirmed a 3-factor structure similar to the original English version. The concurrent validity was supported as 83% (5/6) of the a priori hypotheses were confirmed. Known-groups comparison showed that the questionnaire was unable to differentiate between male and female or urban and rural patients (p > 0.05). Internal consistency and ICC was adequate for the Hausa-PCS total score (α = 0.84; ICC = 0.90) and the subscale helplessness (α = 0.78; ICC = 0.89) but for the subscales rumination (α = 0.69; ICC =0.68) and magnification (α = 0.41; ICC = 0.43). The LOA95% for the Hausa-PCS total score was between –8.10 and +9.75, with SEM and MDC of 3.47 and 9.62 respectively. Conclusion: The Hausa-PCS was successfully developed and psychometrically adequate in terms of factorial structure, concurrent validity, internal consistency and test-retest reliability when applied in mixed urban and rural patients with chronic LBP. However, the internal consistency and reliability coefficients (ICC) for the individual subscales are questionable. Thus, we support the use of the total score when evaluating pain catastrophizing for clinical or research purposes.
