SenseWear Armband and Stroke: Validity of Energy Expenditure and Step Count Measurement during Walking

Table 3

Agreement, standard error of measurement, and absolute percent difference by condition.

Variable, condition	ICC	SEM	Absolute percent difference
EE, SWA hemi versus SWA non-hemi	0.620	0.73	NC
EE, SWA hemi versus metabolic cart	0.586	0.68	17.9 (15.3)
EE, SWA non-hemi versus metabolic cart	0.702	0.48	18.4 (13.3)
Steps, SWA hemi versus SWA non-hemi	0.682	97.92	NC
Steps, SWA hemi versus SAM	0.220	151.5	39.3 (40.4)
Steps, SWA non-hemi versus SAM	0.352	132.34	41.7 (38.0)

EE: energy expenditure; SWA: SenseWear Armband. SEM: standard error of measurement, units are kcal/min for EE, and steps for the steps variable. Values for absolute percent difference are mean (SD). NC: not calculated.
