Table 3. Comparison of pulmonary function and kyphosis angle in pre-test and post-test of muscle energy technique group (N=10)

		Pre test	Post test	t value	p value
Pulmonary function (%)	FVC (L)	4.49±0.62	4.70±0.68	−4.67	0.01*
	FEV1 (L/sec)	4.24±0.53	4.47±0.55	−6.44	0.01*
	PEF (L/sec)	4.81±1.25	4.94±1.30	−0.81	0.44
Kyphosis (deg)		43.90±1.32	34.4±1.19	10.89	0.01*

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