ABSTRACT Objective: To test the construct validity, reliability, and measurement error of the Brazilian Portuguese-language version of the Manchester Respiratory Activities of Daily Living (MRADL) questionnaire in patients with COPD. Methods: We evaluated 50 patients with COPD, among whom 30 were men, the mean age was 64 ± 8 years, and the median FEV1 as a percentage of the predicted value (FEV1%predicted) was 38.4% (interquartile range, 29.1-57.4%). Pulmonary function and limitations in activities of daily living (ADLs) were assessed by spirometry and by face-to-face application of the MRADL, respectively. For the construct validity analysis, we tested the hypothesis that the total MRADL score would show moderate correlations with spirometric parameters. We analyzed inter-rater reliability, test-retest reliability, inter-rater measurement error, and test-retest measurement error. Results: The total MRADL score showed moderate correlations with the FEV1/FVC ratio, FEV1 in liters, FEV1%predicted, and FVC%predicted, all of the correlations being statistically significant (r = 0.34, r = 0.31, r = 0.42, and r = 0.38, respectively; p < 0.05 for all). For the reliability and measurement error of the total MRADL score, we obtained the following inter-rater and test-retest values, respectively: two-way mixed-effects model intraclass correlation coefficient for single measures, 0.92 (95% CI: 0.87-0.96) and 0.89 (95% CI: 0.81-0.93); agreement standard error of measurement, 1.03 and 0.97; smallest detectable change at the individual level, 2.86 and 2.69; smallest detectable change at the group level, 0.40 and 0.38; and limits of agreement, −2.24 to 1.96 and −2.65 to 2.69. Conclusions: In patients with COPD in Brazil, this version of the MRADL shows satisfactory construct validity, satisfactory inter-rater/test-retest reliability, and indeterminate inter-rater/test-retest measurement error.

Abstract Objective The mini-BESTest is a balance measure for assessment of the underlying physiological systems for balance control in adults. Evaluations of test–retest reliability of the mini-BESTest in larger samples of people with multiple sclerosis (MS) are lacking. The purpose of this study was to investigate test–retest reliability of the mini-BESTest total and section sum scores and individual items in people with mild to moderate overall MS disability. Methods This study used a test–retest design in a movement laboratory setting. Fifty-four people with mild to moderate overall MS disability according to the Expanded Disability Status scale (EDSS) were included, with 28 in the mild subgroup (EDSS 2.0–3.5) and 26 in the moderate subgroup (EDSS 4.0–5.5). Test–retest reliability of the mini-BESTest was evaluated by repeated measurements taken 1 week apart. Reliability and measurement error were analyzed. Results Test–retest reliability for the total scores were considered good to excellent, with intraclass correlation coefficients of .88 for the whole sample, .83 for the mild MS subgroup, and .80 for the moderate MS subgroup. Measurement errors were small, with standard error of measurement and minimal detectable change of 1.3 and 3.5, respectively, in mild MS, and 1.7 and 4.7, respectively, in moderate MS. The limits of agreement were − 3.4 and 4.6. Test–retest reliability for the section scores were fair to good or excellent; weighted kappa values ranged from .62 to .83. All items but 1 showed fair to good or excellent test–retest reliability, and percentage agreement ranged from 61% to 100%. Conclusions The mini-BESTest demonstrated good to excellent test–retest reliability and small measurement errors and is recommended for use in people with mild to moderate MS. Impact Knowledge of limits of agreement and minimal detectable change contribute to interpretability of the mini-BESTest total score. The findings of this study enhance the clinical usefulness of the test for evaluation of balance control and for designing individually customized balance training with high precision and accuracy in people with MS.

OBJECTIVES: Clinical conditions such as focal dystonia often require the assessment of atrophy and weakness of the finger muscles. However, due to a lack of well-established protocols, the current investigation focused on assessing the reliability of thickness and strength assessments of the flexor digitorum (FD) muscle, including both the superficialis and profundus components. As a secondary assessment, the reliability of the strength measurement of the extensor digitorum muscle was examined as well. METHODS: Different thickness measurements of the FD were taken via ultrasonography and averaged to estimate the mean thickness of the FD. Likewise, individual finger strength measurements taken by a custom-made finger pressure device were averaged to compute the mean strength of the flexor and extensor digitorum muscles. Test-retest reliability of the above measurements performed at two different time points (about 6 months apart) were examined on the right and left hands of 10 participants. RESULTS: Findings indicated excellent test-retest reliability (ICC > 0.92) for the mean thickness assessment of the FD and mean strength of the flexor and extensor digitorum for both dominant and non-dominant hands. The standard error of measurement was ≤4.3% for all three mean assessments, indicating high sensitivity. Likewise, the smallest detectable change was also sufficiently small for the mean thickness and mean strength of the flexor digitorum (≤5.1%) and moderately small (≤12%) for the strength of the extensor digitorum. CONCLUSIONS: Results indicated an excellent relative and absolute reliability, for both hands, for the mean thickness and strength assessments of the flexor digitorum muscle and for the mean strength of the extensor digitorum (measured for both hands). These measurements can be used for future investigations and can contribute to the establishment of more precise methods for assessing the muscles in the forearms which serve the hand.

Test Retest Reliability

The present study’s aim was to assess the test−retest reliability (TRR) of the ‘Welfare Quality® animal welfare assessment protocol for sows and piglets’ focusing on the welfare principle ‘appropriate behavior’. TRR was calculated using Spearman’s rank correlation coefficient (RS), intraclass correlation coefficient (ICC), smallest detectable change (SDC), and limits of agreement (LoA). Principal component analysis (PCA) was used for deeper analysis of the Qualitative Behavior Assessment (QBA). The study was conducted on thirteen farms in Northern Germany, which were visited five times by the same observer. Farm visits 1 (F1; day 0) were compared to farm visits 2 to 5 (F2–F5). The QBA indicated no TRR when applying the statistical parameters introduced above (e.g., ‘playful‘ (F1–F4) RS 0.08 ICC 0.00 SDC 0.50 LoA [−0.62, 0.38]). The PCA detected contradictory TRR. Acceptable TRR could be found for parts of the instantaneous scan sampling (e.g., negative social behavior (F1–F3) RS 0.45 ICC 0.37 SDC 0.02 LoA [−0.03, 0.02]). The human−animal relationship test solely achieved poor TRR, whereas scans for stereotypies showed sufficient TRR (e.g., floor licking (F1–F4) RS 0.63 ICC 0.52 SDC 0.05 LoA [−0.08, 0.04]). Concluding, the principle ‘appropriate behavior’ does not represent TRR and further investigation is needed before implementation on-farm.

Abstract Introduction Static postural stability is the ability to maintain the posture with minimum sway. Increasing postural sway during standing in different sensory conditions is associated with aging due to decline in sensory and motor functions. Sway area measured by using sway meter is usually simple method for assessing postural stability in elderly subjects. Like many biological measurements, sway area has an intrinsic variability that affects their test-retest reliability and responsiveness of postural stability assessment. The minimal detectable change (MDC) is ability to detect smallest change beyond measurement error that reflects a reliable change. Therefore, the MDC value could provide information of clinical relevance on postural stability. The aims of this study were to determine test-retest reliability and MDC of sway area obtained from sway meter in elderly subjects. Methods Twelve healthy elderly subjects aged 60 years and above were participated in this study. The test and retest repeatability of postural sway measurements were performed twice with a 1-hour interval. For each subject was assess postural sway using Lord’s sway meter during standing on 4 sensory conditions for 30 seconds of each condition. The test-retest reliability of sway area was calculated using intraclass correlation coefficient. The MDC for each sway area was calculated to quantify clinical relevance. Results The test-retest reliability of sway area revealed good to excellent reliability ranged from 0.85 to 0.94. Standard error of measurement (SEM) and MDC ranged from 75 to 205 mm2 and 209 to 568 mm2, respectively. Discussion and Conclusion Our findings reveal that sway area in different sensory conditions could be used in assessment of postural stability in elderly subjects. SEM and MDC of sway area increased when subjects were asked to close their eyes and on foam surface. The sway meter is a reliable tool for assessing postural stability in clinical setting.

BACKGROUND: To date the Neck OutcOme Score (NOOS) was not cross-culturally adapted, validated or available in the Arabic language, although it was available in other languages. OBJECTIVE: To translate and cross-culturally adapt the Arabic version of the Neck OutcOme Score (NOOS-Ar) and study its psychometric properties. METHODS: A sample of 146 subjects with chronic neck pain filled in the NOOS-Ar questionnaire to determine the Cronbach’s alpha (α) for internal consistency, test-retest reliability by intraclass correlation coefficients(2,1) [ICC(2,1)], inter-item correlation, measurement error by coefficient of variance and minimal detectable change, ceiling and floor effects, convergent construct validity with visual analog scale (VAS) by Spearman’s rank correlation coefficient (ρ) and factor analysis to calculate and determine its psychometric properties. RESULTS: Excellent internal consistency (Cronbach’s α> 0.9) and test-retest reliability [ICC(2,1)> 0.9] were observed in NOOS-Ar. None of the five subscales of the NOOS-Ar showed a floor or ceiling effect. The coefficient of variance was generally high, but the minimal detectable change was within the acceptable range (< 30%). The ‘everyday activity and pain’ and ‘symptoms’ subscales of the NOOS-Ar, showed a moderate correlation with VAS. CONCLUSION: The NOOS-Ar is highly reliable and has a moderate to good degree of convergent construct validity with VAS with no floor or ceiling effects.
