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

The effect of transcranial magnetic stimulation test intensity on the amplitude, variability and reliability of motor evoked potentials.
TL;DR: Reduced variability and increased reliability at higher TMS test intensities validate the use of higher T MS test intensity to assess changes in CSE in future research and increase accuracy in capturing true changes inCSE.

An examination chair to measure internal rotation of the hip in routine settings: a validation study.
TL;DR: The use of the examination chair resulted in a precise assessment of hip IR in the authors' population-based inception cohort study of young asymptomatic males and was strongly correlated with standard clinical assessment of IR but was considerably more reliable.
