q3 i? Standardized differences in mean frequency of postural fluctuations were larger in the EA group (58.9 ± 12.7%) than controls (20.3 ± 4.9%; p = 0.036), while sample entropy changes did not differ between groups (p = 0.931). → Chen 2023

q3 · i? · causal · r2

From Table 1 / Fig. 2A analyses of postural fluctuation properties in the randomized stabilometer experiment; MF contrast significant, SampEn contrast null. Both statistics quoted; no standardized effect size printed; impact null.

"The standardized differences in MF of postural fluctuations of the EA group (EA: 58.9 ± 12.7%, control: 20.3 ± 4.9%) were larger than those of the control group (t34 = −2.178, p = 0.036). In contrast, the standardized differences in the SampEn of postural fluctuations did not differ in the two groups ( t34 = 0.088, p = 0.931)"

• Only EA-trained older adults show post-training declines in theta- and alpha-band EEG connectivity strength — related
• Balance training improves dynamic balance performance but not functional balance or postural sway — related
