TL;DR: The findings of this study suggested that, the cloth tape measurement was reliable at all the three different anatomical landmarks of the chest wall and could be used as an outcome measure for chest expansion in the management of cardiorespiratory conditions.
Abstract: Objective: The Objective of this study was to determine the intrarater reliability of chest expansion at three different anatomical landmarks using a cloth tape measure among healthy peoples. Materials and Methods: 120 healthy male and female volunteers were evaluated on two occasions in different days. The measures consisted of chest expansion measurement at axilla, fourth intercostals and xiphoid levels. The measurements were taken in the standing position with the arms hanging sideways at all the three different anatomical landmarks. The test-retest reliability of the measurements was determined by intraclass correlation coefficient (ICC) and standard error of measurements (SEMs). Results : An acceptable reliability was determined by ICC values greater than than 0.85 and SEMs less than 5%. The mean age of the subjects was 21.93 years. ICC of all measures ranged between 0.95 to 0.97 and SEMs were 1.9%, 1.8%, 1.5% at the axillary, fourth intercostals and xiphoid level respectively. Conclusions : The findings of this study suggested that, the cloth tape measurement was reliable at all the three different anatomical landmarks of the chest wall. Therefore, this measurement technique could be used as an outcome measure for chest expansion in the management of cardiorespiratory conditions.

TL;DR: The MCD System demonstrates a very good interrater and intrarater reliability following lower limb surgery in children with CP and may improve standardization of AE recording with a view to accurate audits and improved clarity in outcome studies for CP.
Abstract: BACKGROUND: The modified Clavien-Dindo (MCD) system is a reliable tool for classifying adverse events (AEs) in hip preservation surgery and has since been utilized in studies involving lower limb surgery for ambulant and nonambulant children with cerebral palsy (CP). However, the profile of AEs recorded in children with CP compared with typically developing children is different, and the reliability of the MCD in CP is unknown. This study aimed to evaluate the interrater and intrarater reliability of the MCD system for classifying AEs following lower limb surgery in children with CP. METHODS: Eighteen raters were invited to participate, including clinicians from surgical, nursing, and physical therapy professions, and individuals with CP. Following a MCD familiarization session, participants rated 40 clinical scenarios on 2 occasions, 2 weeks apart. Fleiss' κ statistics were used to calculate interrater and intrarater reliability. RESULTS: The overall Fleiss' κ value for interrater reliability in the first rating was 0.70 (95% confidence interval, 0.61-0.80), and increased to 0.75 (95% confidence interval, 0.66-0.84) in the second rating. The average Fleiss' κ value for intrarater reliability was 0.78 (range, 0.48 to 1.00). Grading of more severe AEs (MCD III to V) achieved near perfect agreement (κ, 0.87 to 1.00). There was a lower level of agreement for minor AEs (MCD I-II) (κ, 0.53 to 0.55). A κ score of 0 to 0.2 was deemed as poor, 0.21 to 0.4 as fair, 0.41 to 0.6 as good, 0.61 to 0.8 as very good, and 0.81 to 1.0 as almost perfect agreement. CONCLUSIONS: The MCD System demonstrates a very good interrater and intrarater reliability following lower limb surgery in children with CP. The MCD can be used by clinicians from different health care professions with a high level of reliability. The MCD may improve standardization of AE recording with a view to accurate audits and improved clarity in outcome studies for CP. LEVEL OF EVIDENCE: Level II-diagnostic.

TL;DR: Isokinetic assessments of thigh muscle strength in postmenopausal women with osteopenia are of high reliability, with a level of agreement comparable to the levels found in previous reliability studies concerning both the healthy elderly and elderly with different health conditions.
