Table 3.

Average (standard deviation) accuracy and precision of the fore-aft parameters and their correlation to the reference system for the full model with arms and the simplified model without arms.

Parameter	Body Model	Accuracy	Precision	Correlation
Vertical distance	With arms	3.3 (19.8)	10.6 (5.4)	0.990 (0.010)
	Without arms	−5.5 (19.7)	10.9 (5.7)	0.989 (0.010)
Fore-aft position	With arms	−73.9 (47.0)	34.0 (11.0)	0.896 (0.087)
	Without arms	−76.7 (49.1)	33.8 (10.9)	0.897 (0.087)

Units for accuracy and precision are mm.
