Table 3.

Mean ± standard deviation values of the trunk flexion (T_ϕ) and extension (T_ε), expressed in degrees

Activity	[deg]			[deg]
	noExo	XoLift	XoHar	noExo	XoLift	XoHar
Lifting	58 13	47 7	47 9	n.a.	n.a.	n.a.
Carrying	8 8	3 4	7 3	−1 10	−3 5	0 5
Lowering	59 13	50 5	49 12	n.a.	n.a.	n.a.

Note: Each row reports the values obtained during the execution of the three different activities (lifting, carrying, and lowering). For lifting and lowering, the T_ε metric was not analyzed, as reported in section “Dynamic fit.”
