Comparison of Dry Needling versus Orthopedic Manual Therapy in Patients with Myofascial Chronic Neck Pain: A Single-Blind, Randomized Pilot Study

Table 2

Comparison of changes in PSC and NDI over time for each treatment group.

Measure	Groups	Baseline mean (SD)	Follow-up mean (95% CI)	Follow-up versus baseline
				Mean difference (95% CI)	value
PSC	DN-S	19.2 ± 6.4	18.2 (15.3 to 21.1)	−1.0 (−3.6 to 1.6)	0.45
	STT	17.5 ± 4.5	16.4 (13.4 to 19.3)	−1.1 (−3.7 to 1.5)	0.41
	OMT	18.3 ± 4.2	13.1 (10.1 to 16.0)	−5.2 (−8.0 to −2.6)	0.001
NDI	DN-S	18.0 ± 5.4	12.2 (8.6 to 15.6)	−5.8 (−9.1 to−2.5)	0.001
	STT	17.4 ± 4.8	15.2 (11.6 to 18.7)	−2.2 (−5.5 to 1.0)	0.17
	OMT	18.5 ± 3.2	10.0 (6.5 to 13.5)	−8.6 (−11.8 to −5.2)	0.001

PSC = pain catastrophizing scale, NDI = neck disability index, DN-S = dry needling + stretching, STT = soft tissue techniques, OMT = orthopedic manual therapy, and 95% CI = 95% confidence interval. .
