Table 2.

Bland-Altman analysis was used to calculate the percentage bias (limits of agreement [LOA]) between tidal volume measured with spirometry and tidal volume measured with the Hexoskin.

Session	Task, median % bias (median LOA)
	Lying (N=15)	Sitting (n=14)	Standing (N=15)	Bend-over sitting (N=15)	Vacuuming (n=12)	Walking with weights (n=12)	Stair walking (n=13)
Session 1	0.0 (5.6)	–0.2 (12.7)	–0.2 (12.0)	–0.4 (10.8)	–0.6 (16.7)	–0.3 (11.1)	–0.5 (12.6)
Session 2	7.5 (6.7)	–6.4 (14.7)	–8.5 (13.0)	3.3 (10.6)	–8.9 (16.4)	–7.3 (12.0)	–4.5 (15.0)
