Motion capture marker standard deviation

	Measure	VR with Perturbations	VR without Perturbations	Unaltered View
Head marker	Train (%change)*	16.1% (19.7%)	−0.9% (6.4%)	−6.8% (18.2%)
	Test (%change)	2.7% (29.1%)	−5.3% (22.8%)	6.8% (28.3%)
	Train (cm)	5.8 (1.1)	6.0 (0.8)	7.4 (2.1)
Sacrum marker	Train (%change)	3.9% (8.7%)	0.7% (9.5%)	−5.7% (10.3%)
	Test (%change)	−8.5% (20.4%)	6.7% (28.0%)	−8.2% (15.8%)
	Train (cm)	5.1 (0.8)	5.2 (0.8)	4.5 (0.6)

Average values for head and sacrum markers standard deviation during training along with percent change during training and testing for both virtual reality (VR) groups and unaltered view (n = 10 for each group). Standard deviations are in parentheses. Head marker percent change during training significantly differed between groups, denoted with an asterisk (post hoc t-test with Bonferroni correction following significant ANOVA; P < 0.05). We found no other significant differences.
