Relationship between RQs of Sway Area and AP Spectrum Level and between RQs of Path Length and AP Median Frequency in the non-adapted and adapted trials.

RQ	Condition		Equation	R2	Slope different from zero	Foam vs. Solid
Sway area vs. AP spectrum level	Non-adapted	Foam	y = 0.98 x + 0.08	0.69	p < 0.001	p = 0.54
		Solid	y = 0.77 x + 0.32	0.52	p < 0.001
	Adapted	Foam	y = 1.11 x - 0.16	0.58	p < 0.001	p = 0.22
		Solid	y = 1.24 x + 0.11	0.69	p < 0.001
Path length vs. AP median frequency	Non-adapted	Foam	y = 0.89 x + 0.94	0.11	p = 0.15	p = 0.19
		Solid	y = −0.03 x + 1.55	0.00007	p = 0.97
	Adapted	Foam	y = 1.30 x - 0.35	0.07	p = 0.26	p = 0.57
		Solid	y = −0.18 x + 1.81	0.002	p = 0.84
