TL;DR: HHD is a reliable method of measuring shoulder strength in the clinical setting, however, when several examiners are testing strength of stronger subjects in abduction of the scapular plane, stabilizing the dynamometer provides more reliable results.
Abstract: BackgroundReliable measurements of shoulder strength are important in assessing rotator cuff integrityAimTo determine whether a fixed strength assessment device is more reliable than a handheld dy

TL;DR: The single-legged hop tests and isokinetic muscle torque measurements demonstrated moderate-to-high reliability with low measurement error in sports-active children.
Abstract: Single-legged hop tests and isokinetic muscle torque are common outcome measures in the evaluation of knee function. The reliability of the single-legged hop tests in children has not been documented. The aim was to examine inter- and intrarater reliability of four single-legged hop tests and isokinetic muscle torque measurements in children. Twenty-eight sports-active children (12.4 ± 0.3 years old) were tested three times in two test sessions separated by 1 week. They performed four single-legged hop tests and concentric isokinetic torque measurements during knee extension and flexion. Inter- and intrarater reliability were calculated using the intraclass correlation coefficient (ICC 2,1). Relative terms of the standard error of measurement (SEM %) and smallest real difference (SRD %) were emphasized to allow comparison between the different variables. Twenty-six children were included for statistical analysis. ICCs for inter- and intrarater reliability were moderate to high for the hop tests (0.62–0.91) and isokinetic measurements (0.76–0.87). SEMs % were low for the hop tests (3.9–7.4 %) and the isokinetic measurements (5.2–8.9 %). SRDs % were 20.5 % or less for the hop tests, 15.7 % or less for knee extension, and 24.6 % or less for knee flexion. The single-legged hop tests and isokinetic muscle torque measurements demonstrated moderate-to-high reliability with low measurement error in sports-active children. A change above 20.5 % for the single-legged hop tests, 15.7 % for knee extension, and 24.6 % for knee flexion is necessary to represent a real change in knee function. III.

TL;DR: In this article, the intra-rater reliability of USI measures of the thickness and percentage thickness change of the external oblique, internal oblique (IO), and transversus abdominis (TrA) on both sides of the body during the active straight leg raise (ASLR) test in healthy adolescents was assessed.
Abstract: Background To date, the reliability of ultrasound imaging (USI) measures of the abdominal muscles in children and adolescents during the active straight leg raise (ASLR) test has not been confirmed. Objective To assess the intra-rater reliability of USI measures of the thickness and percentage thickness change of the external oblique (EO), internal oblique (IO), and transversus abdominis (TrA) on both sides of the body during the ASLR test in healthy adolescents. Design Single-group repeated-measures intra-rater reliability study. Setting School. Participants Thirty-nine adolescents between the ages of 13 and 16 years. Methods Three repeated USI measurements were recorded in the supine resting position and during the ASLR test at 2 sessions, 6 to 8 days apart. In the supine position, measurements were collected at the end of normal expiration. In the case of ASLR, measurements were collected when the person undergoing examination touched the transverse delimiter with the distal part of their lower leg, that is, to a 30° flexion of the hip. Main Outcome Measurements USI of abdominal muscle thickness. Results By using the mean of 3 measures in the supine, resting position, intra-examiner reliability point estimates (intraclass correlation coefficient [ICC] 3.3 ) ranged from 0.95 to 0.97 for EO, IO, and TrA. During the ASLR test, the ICC result of thickness measurements of all muscles was also above 0.90. In terms of percentage change of muscle thickness, the highest ICC 3.3 result obtained for the TrA was 0.81-0.85; for EO the result ranged from 0.72-0.89, and the result for the IO was between 0.65 and 0.79. Conclusion USI measurements of the thickness of the EO, IO, and TrA muscles at rest and during the ASLR test in healthy adolescents between 13 and 16 years of age are reliable. Because of an increase in the precision of measurements, we recommend using the mean of 3 consecutive measurements of the EO, IO, and TrA muscles in adolescents to ensure a good reliability level. Based on 3 consecutive measurements, good reliability for the percentage change in the TrA thickness was achieved.

TL;DR: Substantial reliability was found for revised ASRM endometriosis diagnosis, whereas moderate reliability was observed for staging, suggesting that reliability in endometiosis diagnosis is not greatly altered by location or composition of surgeons, supporting the conduct of multisite studies or compilation of endometrian data across clinical centers.

TL;DR: This paper presents a meta-modelling framework that automates the very labor-intensive and therefore time-heavy and therefore expensive and expensive process of manually cataloging and rebuilding weak links in a distributed system.
Abstract: Considerable commonality exists between reliability and security. Both are weak-link phenomena. Good design involves avoiding single weak links. However, on many occasions, multiple weak links can be, and have been, known to occur — accidentally or intentionally.
