Subclaims¶

q3 i? The EA group showed greater declines in ankle–plate mutual information than controls (−26.6 ± 4.8% vs 2.3 ± 8.6%, p = 0.023), and greater reductions in ankle movement RMS (−40.0 ± 3.1% vs −28.8 ± 6.2%, p = 0.041). → Chen 2023

q3 · i? · causal · r2

Independent t tests on standardized differences in ankle kinematics (RMS) and ankle–plate mutual information (AP-MI) from the same randomized stabilometer experiment; AP-MI declined only in EA, indicating decoupling. Effect size not printed for these contrasts; impact null.

"the EA group exhibited greater reductions in the standardized differences in the RMS of ankle movement ( t34 = 2.127, p = 0.041)(EA: −40.0 ± 3.1%, control: −28.8 ± 6.2%) and AP-MI ( t34 = 2.377, p = 0.023)(EA: −26.6 ± 4.8%, control: 2.3 ± 8.6%) than the control group did."
