Reliability of COP-based postural sway measures and age-related differences

Reliability of postural control measures in children and young adolescents

“…It represents an expression of the energy spent by the postural system to maintain balance [27]. Our result is in line with previous studies reporting mean sway velocity as the most reliable traditional parameter in adults and children [12,18,28,29]. In children aged 6-14 years, the sX value showed a moderate reliability in all conditions.…”

The test–retest reliability of centre of pressure measures in bipedal static task conditions – A systematic review of the literature

“…The most commonly applied statistic however, were the different forms of the intraclass correlation coefficient (ICC). While most used models described originally by Shrout and Fleiss [13], others again employed modified versions [14]. About 30% (6/22) of the studies using the ICC failed to state the exact model used.…”

“…The corresponding authors of these studies were contacted in order to gather the missing information but only two replies [14,15] were received. Where ICC models were reported, the twoway random effect model (ICC2,1) was employed most often.…”

“…With regards to differences between within-day and between-day reliabilities, it has been shown that trials run on the same day yield higher values [10,14]. While intra-trial and inter-trial reliability needs to be discussed, inter-rater reliability is unlikely to be of concern due to the simplicity of the apparatus, task and instructions.…”

Intersession reliability of a posturo-stabilometric test, using a force platform

“…A survey of the PubMed MEDLINE database and a review article (Ruhe et al, 2010) shows that some articles (Corriveau et al, 2000;Lafond et al, 2004;Lin et al, 2008;Salavati et al, 2009;Santos et al, 2008) assessed the reliability of the force plate examination, considering only the intrasession variability, obtaining excellent results. The intersession reliability was the subject of a recent study by Perinetti et al (2012).…”
