Table 2. Comparison of VAS, PPT, and NDI between the pre-test and post-test in each group (Mean±SD).

	Experimental group (n=16)		Control group (n=16)
	Pre-test	Post-test	Pre-test	Post-test
VAS	7.13±0.81	5.00±1.26	7.31±1.08	4.94±1.44
PPT	35.64±9.51	39.35±8.46	33.48±9.69	36.88±8.58
NDI	26.81±5.67	21.56±5.41	26.94±4.51	22.75±4.52

*p<0.05, VAS=visual analog scale, PPT=pressure pain threshold, NDI=neck disability index
