Table 1. Comparison of pulmonary function and kyphosis angle in pre-test and post-test of control group (N=10)

		Pre test	Post test	t value	p value
Pulmonary function (%)	FVC (L)	4.34±1.13	4.19±1.07	2.74	0.02
	FEV1 (L/sec)	3.49±0.64	3.49±0.65	−0.30	0.77
	PEF(L/sec)	5.62±0.92	5.67±1.16	−0.027	0.80
Kyphosis (deg)		43.50±0.97	43.40±0.95	0.29	0.78

Data are expressed as mean±SD. FVC, forced vital capacity; FEV1, forced expiratory volume in 1sec; PEF, peak expiratory flow; ^* p<0.05.
