Physical function of the upper limbs and BI of the two groups ($\overline{x}\pm s$).

Group		FMA	BI
VFT (n = 16)	Baseline	21.76 ± 6.89	42.75 ± 11.09
	8th week	43.85 ± 6.42ab	72.33 ± 11.82ab
	t	7.51	9.56
	P	0.03	<0.001
CTL (n = 15)	Baseline	22.01 ± 5.67	43.78 ± 12.11
	8th week	38.31 ± 7.36a	63.75 ± 10.45a
	t	6.42	7.22
	P	0.04	0.03

Note: BI, Barthel Index; VFT, visual feedback therapy; CTL, control; FMA, Fugl–Meyer assessment; ^a means P < 0.05 compared with baseline data; ^b means P < 0.05 compared with data of CTL group.
