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

Comparison of shoulder rotation range of motion in professional tennis players with and without history of shoulder pain
TL;DR: In professional tennis players, limited IR ROM rather than a GIRD seems to be associated with shoulder pain history, duration of tennis practice and the players' age, when compared to a similar cohort with no history of shoulder pain.

TL;DR: The metrological qualities of techniques currently used to quantify skeletal muscle volume and 3D shape in healthy and pathological muscles are reported to help the choice of appropriate segmentation techniques, according to the purpose of the measurement.

Time to Readiness for Discharge is a Valid and Reliable Measure of Short-Term Recovery After Colorectal Surgery
TL;DR: The results of this research support the construct-validity and reliability of TRD as a measure of short-term recovery and may reduce sample size requirements in future RCTs.

Long-term stability of tensiomyography measured under different muscle conditions.
TL;DR: The level of reliability of TMG tended to increase after the maximal voluntary contraction and the fatigue protocol were administered, probably because of more controlled conditions preceding the measurement.

Inter-tester reliability of scapular position in junior elite swimmers
TL;DR: Measurement of scapular position in an athletic population appears to be as reliable as in non-athletic populations, but a sport-specific position such as full flexion may highlight subtle impairments, but has decreased reliability for the Superior Kibler.

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.
