Longitudinal Validity

AbstractBackground and aimsThe Core Outcome Measures Index (COMI) is a short, self-reported questionnaire for assessing important outcomes in patients with low back pain (LBP). The present study was conducted to explore the responsiveness and longitudinal validity of the Persian COMI (COMI-P) in patients with non-specific chronic LBP.MethodsIn this prospective cohort study of patients with non-specific chronic LBP receiving physiotherapy, patients completed a booklet containing the COMI-P, Persian Functional Rating Index (FRI-P), and a visual analogue scale (VAS) for pain before and after the end of ten-sessions of physiotherapy. Patients also completed a global rating of change scale (GRCS) at the end of the physiotherapy. Responsiveness was examined by means of internal responsiveness methods [t-test, standard effect size (SES); standardized response mean (SRM), and Guyatt responsiveness index (GRI)] and external responsiveness methods [correlation with external criteria and receiver operating characteristics (ROC) curve].ResultsFifty patients with a mean age of 50.62 ± 13.8 years participated. The paired t-test showed significant changes in COMI-P scores (p < 0.001). The effect sizes for COMI-P were large (range 0.96–1.23). The score changes for the COMI-P revealed significant correlations with FRI-P (r = 0.67, p < 0.001), the VAS (r = 0.65, p < 0.001), and the GRCS (r = 0.34, p = 0.02). The COMI-P change scores showed excellent correlation with the dichotomized smallest detectable change (SDC) criterion (r = 0.83, p < 0.001). The ROC area under the curve for the COMI-P based on the dichotomized SDC criterion was perfect. The minimal clinically important change was estimated 2.15 points (sensitivity 94% and specificity 100%).ConclusionsThe COMI-P appears to have responsiveness and longitudinal validity in detecting changes after physiotherapy for non-specific chronic LBP. An improvement of 2.15 points in COMI-P total score is required to be interpreted as minimally clinically important change in individual patients.

Abstract Background Low back pain (LBP) is a common musculoskeletal problem, associated with disability and high societal costs. The Oswestry Disability Index (ODI) is among the most commonly used patient reported outcome measures to measure disability due to LBP. Evidence supporting the reliability and validity of the Nepali Version of Oswestry Disability Index (NODI) exists, but its responsiveness is yet to be assessed. Objective We aimed to assess the responsiveness of NODI in participants with non-specific low back pain. Methods The study included 102 (Male 41, Female 61) participants with non-specific low back pain, attending the physiotherapy outpatient department of a tertiary care hospital and nearby community. The NODI was administered to the patients at baseline and again 2 weeks later along with a 7-item Nepali Version of Global Rating of Change (GROC-NP). Responsiveness of NODI was assessed by plotting Receivers Operating Characteristics (ROC) curve. Results The area under curve (AUC) of NODI was 0.88. The best cut-off point on the NODI for improvement on the GROC-NP or the minimal clinical important change (MIC) was 4.22 and ranged from 3.11 to 6.34. The sensitivity and specificity was 77.4% and 84.2% respectively. Conclusion NODI is a responsive scale which can discriminate between participants whose level of disability due to LBP is stable or improving. The result for minimal clinically important change, sensitivity and specificity are consistent with other cross culturally adopted versions.

Context: The importance of isometric trunk strength (ITS) among sport science professionals is higher than its actual reported effect size on either performance or low back pain (LBP) occurrence. Objective: To provide normative values of ITS and strength ratios, and to evaluate the effect of sex, sports discipline, and LBP status. Design: Crossover study. Setting: University research laboratory. Participants: Five hundred and sixty-seven elite athletes (186 females) with and without a history of LBP from different sports. Main Outcome Measure: Participants underwent ITS testing for trunk flexors, extensors, and lateral flexors. Normalized maximal strength (in newton meter per kilogram) and strength ratios were calculated. Differences between sex, LBP, and sport disciplines were assessed with 3-way analysis of variance (sex × LBP status × 7 sport categories) and partial eta-squared () effect size. The predictive validity of ITS for LBP was checked with receiver operating characteristics (area under the curve). Results: The authors found significant differences in extensor and flexor ITS in favor of male athletes (medium , P < .05), while sex differences in lateral flexion ITS had a low size effect (P < .05). A low size effect was also observed for the differences in strength ratios extensors/flexors (mean 1.47; 95% confidence interval, 1.45–1.50) and left flexors/right flexors (mean 0.99; 95% confidence interval, 0.98–1.01) among sexes. The sport discipline-related differences generally had a low size effect. No significant differences in ITS were found between LBP and LBP-free athletes. Only 50% to 58% of athletes (area under the curve, 0.501–0.582) were correctly classified as LBP or LBP-free using different ITS and strength ratio variables. Conclusions: ITS and strength ratios have low predictive validity for LBP history but may discriminate between sex and sport disciplines. Our data are a useful reference point for meaningful individual results interpretation when athletes are evaluated during training or rehabilitation.

Abstract Objectives Low back pain (LBP) is the leading cause of disability and a global public health concern. Studies indicate that pain self-efficacy is associated with the development of disability in chronic LBP (CLBP) patients. The Pain Self-Efficacy Questionnaire (PSEQ) is a commonly used questionnaire to assess pain self-efficacy in patients with CLBP. It is essential to examine the psychometric properties of the PSEQ in the population in which it is to be used. Thus, the aim of this study is to evaluate the reliability and smallest detectable change of the Danish version of the Pain Self-Efficacy Questionnaire (PSEQ-DK) in patients with CLBP before implementing it as an outcome measure in an inpatient rehabilitation context. Methods This observational study including 92 patients with CLBP was conducted in a multidisciplinary rehabilitation facility in Denmark. The psychometric properties statistically tested included reliability, smallest detectable change and floor and ceiling effect of the PSEQ-DK. Results The reliability analysis included 92 patients and revealed an weighted kappa of 0.82 (95% Cl 0.75; 0.88) and Intraclass correlation coefficient of 0.83 (95% CI 0.75; 0.88), which corresponds to a good reliability. The smallest detectable change was 12.67. Conclusions The present study demonstrated that the PSEQ-DK had a good reliability in patients with CLBP in an inpatient rehabilitation context. The current results expand our knowledge of the reliability and smallest detectable change of the PSEQ-DK. In order to implement PSEQ-DK in a rehabilitation context for evaluative purposes future studies should focus on examining responsiveness and interpretability.

AbstractBackground:Low back pain (LBP) is a very frequent condition, affecting most people at some point throughout their life. This cross-sectional study was aimed to investigate a selected panel of cytokines and inflammatory biomarkers in patients with or without LBP.Methods:The study population consisted of 104 patients diagnosed with LBP (52 non-persistent and 52 persistent) and 52 healthy subjects with no LBP. Blood samples were collected for assessment of adiponectin, leptin, monocyte chemoattractant protein-1 (MCP-1) and C reactive protein (CRP). The duration of LBP was categorized as “no pain”, “non-persistent LBP” and “persistent LBP”.Results:Higher values of CRP and lower concentrations of both leptin and MCP-1 were found in LBP patients compared to controls, whereas adiponectin did not differ among groups. MCP-1 was also lower in patients with non-persistent than in those with persistent LBP. Age, leptin (relative risk, 11.8; 95% CI, 3.9–35.8) and MCP-1 (relative risk, 2.7; 95% CI, 1.7–4.4) were independently associated with presence and duration of LBP. The combination of age, leptin and MCP-1 predicted 61% of the risk of LBP duration. The area under the curve of MCP-1 for distinguishing persistent from non-persistent LBP was 0.65 (95% CI, 0.54–0.76).Conclusions:Then results of our study suggest that leptin and MCP-1 may be promising biomarkers for diagnosis of acute LBP and its risk to become chronic.
