A Comparative Study of Smartphone Game with Spirometry for Pulmonary Function Assessment in Stroke Patients

Table 2

Mean ± SD and reliability measured with smartphone-game application.

	Mean ± SD	ICC (2,1) 95%CI	95% LOA	SEM	SEM (%)	MDC	MDC (%)	CV (%)
Intra-test	8.4 ± 0.92	0.84	0.30~2.33	0.37	4.41	1.02	12.22	24.84
		(0.65-0.93)
Inter-test	8.9 ± 0.18	0.96	1.66~3.80	0.3	0.41	0.10	1.16	15.04
		(0.91-0.98)

CV=coefficients of variation of method error; ICC=intracorrelation coefficient; LOA=limits of agreement; MDC=minimum detectable change; SEM=standard error of measurement.
