Effects of Wuqinxi in the Patients with Chronic Low Back Pain: A Randomized Controlled Trial

Table 3

The changes in pain intensity from baseline to 12 and 24 weeks.

Outcomes	Difference in mean change (95% CI)		Between-group difference (95% CI)
	WQXG	GEG	GEG vs. WQXG	P
SF-MPQ (0–45)
Week 12	−9.8 (−11.9 to −7.6)	−7.9 (−10.4 to −5.3)	−1.7 (−3.5 to 0.01)	0.051
Week 24	−13.3 (−15.4 to −11.2)	−11.4 (−13.9 to −8.9)	−1.7 (−3.2 to −0.2)^#	0.032
VAS (0–10)
Week 12	−2.5 (−3.2 to −3.8)	−1.9 (−2.8 to −1.0	−0.3 (−1.0 to 0.4)	0.357
Week 24	−4.0 (−4.7 to −3.4)	−2.8 (−3.8 to −1.9)	−0.9 (−1.8 to −0.1)^#	0.035
PPI (0–5)
Week 12	−1.4 (−1.8 to −1.0)	−1.2 (−1.7 to −0.7)^∗	−0.3 (−0.7 to 0.1)	0.166
Week 24	−2.1 (−2.5 to −1.7)	−1.6 (−2.1 to −1.1)	−0.6 (−1.0 to −0.1)^#	0.014

The pain intensity was assessed by SF-MPQ, and VAS and PPI as subtables were used for further evaluation. The changes in mean were calculated from the difference between the current value and the baseline data. Compared with baseline, ; compared with the GEG at the same time point, ^#. CI, confidence interval; WQXG, Wuqinxi group; GEG: general exercise group; SF-MPQ: Short-Form McGill Pain Questionnaire; VAS: Visual Analog Scale; PPI: Present Pain Intensity.
