Sample size and optimal designs for reliability studies
TLDR
A functional approximation to earlier exact results is shown to have excellent agreement with the exact results and one can use it easily without intensive numerical computation.Abstract:
A method is developed to calculate the required number of subjects k in a reliability study, where reliability is measured using the intraclass correlation rho. The method is based on a functional approximation to earlier exact results. The approximation is shown to have excellent agreement with the exact results and one can use it easily without intensive numerical computation. Optimal design configurations are also discussed; for reliability values of about 40 per cent or higher, use of two or three observations per subject will minimize the total number of observations required.read more

Ultrasound-observed tendon abnormalities in lateral epicondylalgia: Exploring associations with neurosensory and clinical outcomes
TL;DR: This thesis demonstrates that the composite US scoring method has good inter-and intra-rater reliability in grading tendon abnormalities in LE and investigates the effectiveness of prolotherapy injections, manual therapy/exercise, both singly and in combination in improving tendon structural and sensory abnormalities over time.

The intra-rater reliability of anthropometric data collection conducted on the peripubescent foot: A pilot study
TL;DR: In this article, the authors evaluated the intra-rater reliability of repeated measures of forefoot width weightbearing, fore foot width non-weightbearing, navicular height and navicular drop conducted on the peripubescent foot.

Reproducibility of the Six-Minute Walk Test in Children and Youth with Juvenile Idiopathic Arthritis.
TL;DR: This study undertook this study to evaluate reproducibility (agreement and test–retest reliability) and to determine standard error of measurement (SEM) and smallest detectable difference (SDD) in children and youth with JIA.
