Abstract: Objectives . To examine the interrater and intrarater reliability and construct validity of the Pain Behaviour Scale during standard physical performance tests in people with chronic low back pain and to confirm the test-retest reliability of the physical performance tests in this population. The Pain Behaviour Scale (PaBS) is an observational scale that was recently designed to uniquely measure both the presence and severity of observed pain behaviours. Methods . Twenty-two participants with chronic low back pain were observed during performance of five physical performance tests by two raters. Pain behaviours were assessed using the Pain Behaviour Scale. The Visual Analogue Scale and Modified Oswestry Disability Index were used to measure pain and disability, respectively. Descriptive statistics were used to report demographic features of participants. Reliability was analyzed using ICCs. Rater agreement was analyzed using the weighted Cohen’s kappa. Correlations between PaBS, self-reported measures, and physical performance tests were calculated using Pearson’s product-moment correlations. Results . The PaBS demonstrated excellent interrater (ICC 2 , 1 = 1.0, 95% CI: 0.9 to 1.0) and intrarater (ICC 3,1 = 0.9, 95% CI: 0.8 to 1.0) reliability. Component physical performance tests (i.e., time and distance) demonstrated good test-retest (0.6–1.0) reliability. Perfect agreement in the reporting of pain behaviours was found (95–100%). Correlations between pain behaviour severity and pain intensity ( r = 0.6) and disability ( r = 0.6) were moderate. Moderate correlations were found between pain behaviours and physical performance tests in sit to stand ( r = 0.5), trunk flexion ( r = 0.4), timed up and go ( r = 0.4), and 50-foot walk ( r = 0.4). Conclusion . The Pain Behaviour Scale is a valid and reliable tool for measuring the presence and severity of pain behaviour, and the physical performance tests are reliable tests.

Abstract: Chronic low back pain (CLBP) is a major health problem. Identifying prognostic factors is essential for identifying people at risk of developing CLBP-related disability. To examine associations between CLBP-related disability at 12-month follow-up and in idual, psychosocial and physical factors at baseline, as well as treatment-related factors between baseline and 12-month follow-up among a Saudi population. Additionally, associations between pain intensity and general perceived efficacy (GPE) at 12 months were examined with the aforementioned factors. A prospective cohort study. One hundred Saudi participants over 18 years with a history of LBP greater than 3 months' duration. The primary outcome variable was CLBP-related disability measured by the Arabic Oswestry disability index. Secondary outcome measures were pain intensity over the prior week measured by the VAS and the participant's global perceptions of recovery (general perceived efficacy [GPE]) at 12 months. At baseline (n=115), participants completed questionnaires covering demographics, disability, pain intensity, back beliefs, fear avoidance, psychological distress, and physical activity. They performed standardized physical performance tests, including assessment of pain behaviors using a pain behavior scale. After 12 months, participants (n=100) completed questionnaires on disability, pain intensity, GPE and provided treatment-related information during the previous year. Predictors of disability, pain, and GPE were explored using univariate and multivariate regression analyses. The prognostic model for moderate-severe CLBP-related disability at 12 months explained 53.0% of the variance. Higher pain intensity, higher fear-avoidance work, and older age predicted higher disability. Having no additional somatic symptoms predicted lower disability. Pain intensity at 12-month follow-up was explained by higher disability at baseline, while not being in paid employment appeared protective (25.7% of variance explained). As univariate associations were weak between predictor variables and GPE, multivariate analysis was not conducted. The study results supported the multifactorial nature of CLBP and reported an important prognostic model in the Saudi population.

Abstract: To determine whether bioimpedance spectroscopy was suitable for detection of hand lymphoedema. The hands of 50 participants without a history of lymphoedema were measured with perometry and bioimpedance spectroscopy after positioning two ways for three minutes: (a) both hands rested at heart height and (b) the dominant hand at heart height and the non-dominant hand at head height. In addition, 10 women with secondary hand lymphoedema were also measured. Impedance and volume measurements were found to be strongly related (dominant hand r = −0.794). Both measurements were reliable (ICC 2,1 = 0.900–0.967 and 0.988–0.996, respectively). Impedance was more sensitive to small changes in hand volume due to the postural change (position × device interaction: F = 23.9, P 0.001). Finally, impedance measurements had better discrimination of women with lymphoedema than volume measurements. Bioimpedance spectroscopy is a promising tool for the detection of secondary hand lymphoedema.
