TLDR
It is recommended that sports clinicians and researchers should cite and interpret a number of statistical methods for assessing reliability and encourage the inclusion of the LOA method, especially the exploration of heteroscedasticity that is inherent in this analysis.Abstract:
Minimal measurement error (reliability) during the collection of interval- and ratio-type data is critically important to sports medicine research. The main components of measurement error are systematic bias (e.g. general learning or fatigue effects on the tests) and random error due to biological or mechanical variation. Both error components should be meaningfully quantified for the sports physician to relate the described error to judgements regarding ‘analytical goals’ (the requirements of the measurement tool for effective practical use) rather than the statistical significance of any reliability indicators.read more

Concentric and eccentric isokinetic knee extension: A reproducibility study using the IsoMed 2000-dynamometer
TL;DR: High reproducibility was shown for the IsoMed 2000-dynamometer in measuring PT during concentric and eccentric knee extension, however, due to a systematic practice-based improvement found for eccentric measurements, it is suggested to do a familiarisation session prior the actual testing sessions in practice.

Between-day reliability of centre of pressure measures for balance assessment in hemiplegic stroke patients
David Gasq,Marc Labrunee,David Amarantini,David Amarantini,David Amarantini,Philippe Dupui,Richard Montoya,Philippe Marque +7 more
TL;DR: In clinical practice, the CoP-based velocity variables should be prefer to CEAREA to assess and monitor postural sway over time in hemiplegic stroke patients, because the poor reliability of CoPML compromises its use to assess weight-bearing asymmetry.

Reliability and validity of the lung volume measurement made by the BOD POD body composition system.
James A. Davis,Silvia Dorado,Kathleen A. Keays,Kimberly A. Reigel,Kristoffer S. Valencia,Patrick H. Pham +5 more
TL;DR: The purpose was to determine the reliability and validity of the BOD POD FRC measurement at end‐exhalation and it is concluded that the B OD PODFRC measurement in healthy males and females is both reliable and valid.

Auditory steady-state responses in normal hearing adults: A test-retest reliability study
Wendy D'haenens,Bart Vinck,Eddy De Vel,Leen Maes,Annelies Bockstael,Hannah Keppler,Birgit Philips,Freya Swinnen,Ingeborg Dhooge +8 more
TL;DR: In this article, the test-retest reliability of an 80-Hz multiple-ASSR system in normal-hearing subjects was assessed by a comprehensive set of statistical methods, which consisted of Pearson productmoment correlation, analysis of variance (ANOVA), and standard error of measurement (SEM).

TL;DR: IAT and MAT could be useful and reliable and valid tests to analyse CODA in FPCP and could be applied considering the cut point that classifiers need to make a decision about the FT8 class and the other FT classes (FT5, FT6, and FT7).

Statistical methods for assessing agreement between two methods of clinical measurement
TL;DR: In this article, an alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability, which is often used in clinical comparison of a new measurement technique with an established one.

A concordance correlation coefficient to evaluate reproducibility.
TL;DR: A new reproducibility index is developed and studied that is simple to use and possesses desirable properties and the statistical properties of this estimate can be satisfactorily evaluated using an inverse hyperbolic tangent transformation.
