Table 4.

Accuracy of the answers (answer error mean) of each group for each visual condition

	BL	Full vision	Limb+Obs	Obs
PD	1.75(±0.29)	2.53(±0.30)a	2.29(±0.43)	2.37(±0.29)b
HC	1.51(±0.31)	2.00(±0.33)	1.42(±0.47)	1.64(±0.32)

Legend - BL = base line condition (performing the cognitive task sitting on a chair); ^adifferent from baseline p < 0.05; ^bdifference between groups p < 0.05.

Greater numbers represent worse performance. A zero score would represent an exact answer.
