Age and gender effects on postural control measures

The effect of footwear on postural control in bipedal quiet stance

“…The former would suggest that women and men might control upright posture differently. Current research on gender differences in postural control yielded inconsistent results: one study found no gender effects (Hageman et al 1995), while other studies reported some differences between the sexes (Wolfson et al 1994, Farenc et al 2003. The interaction effect between gender and shoe condition suggests that women and men might respond differently to an unstable shoe.…”

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

“…While about half the authors described the baseline demographics in appropriate detail (18/32, 56%), only one study included a physical examination in order to validate their health status prior to study enrollment [8]. The other authors relied only on self-reports or did not provide any description at all.…”

“…Most studies enrolled mixed-gender groups which have shown high correlation coefficients [8]. In addition, even though it has been shown that COP measures differ between age groups [8,28,29], the reliability of these measures is not influenced by gender. Demura et al showed excellent reliability for a selection of different COP measures in both young and elderly subjects [29].…”

“…Under eyes closed conditions the reliability is lower for short sampling durations and rises as the individual adapts [43], leading to higher overall reliability values under eyes closed condition compared to eyes open [8,9,11,17,22,37,38,40,45,46].…”

Body Mass Index and Functional Mobility Outcome Following Early Rehabilitation After a Total Knee Replacement: A Retrospective Study in Taiwan

“…Studies of healthy elderly individuals have shown that the FRT is a reliable and valid measure of balance, with an intraclass correlation coefficient (ICC) of 0.75-0.99 (39). Previous studies have shown that body height significantly influences FRT results, with the reaching distance increasing 3.3 cm for every additional 10 cm of body height (40)(41)(42). Therefore, we normalized the FRT score by calculating the ratio of reaching distance to body height, using the following equation, as previously described (41): (reaching distance in cm/height in cm) 3 100.…”
