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

Foot-Worn Inertial Sensors Are Reliable to Assess Spatiotemporal Gait Parameters in Axial Spondyloarthritis under Single and Dual Task Walking in Axial Spondyloarthritis.

TL;DR: Spatiotemporal gait parameters obtained from foot-worn inertial sensors assessed in patients with axSpA in single- and dual-task conditions are reliable, however, symmetry and DTE parameters seem less reliable and need to be interpreted with caution.

Measuring changes in activity limitation and participation restriction in people with COPD
TL;DR: The test-retest reliability of the Patient-Specific Functional Scale and the London Handicap Scale for people with chronic obstructive pulmonary disease indicates that both scales could be suitable for testing hypotheses in groups of people with COPD.

Variability of angular measurements of head posture within a session, within a day, and over a 7-day period in healthy participants.
TL;DR: Investigating the variability of angular measurements indicative of forward HP, head extension, and side flexion within a session, within a day, and over a 7-day period found that forward HP was stable and head extension was found to be less stable.
