Subclaims¶

q3 i? The EA group reduced postural errors more than the control group after one training session (−46.5 ± 4.7% vs −27.1 ± 4.0%, p = 0.020). → Chen 2023

q3 · i? · causal · r2

Randomized between-groups parallel experiment with 36 older adults (n = 18 per group); one 60 s-round training day between pre- and post-tests. The independent t test on standardized error differences favored EA, "better training benefits in the EA group". No standardized effect size printed; impact null.

"The results of independent t statistics showed better training benefits in the EA group, as indicated by the greater reduction in the standardized differences in postural errors between the pre-test and post-test ( t34 = 2.440, p = 0.02)"
