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

Table 4

The changes in the quality of life 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-36 PCS
Week 12	13.6 (7.7 to 19.4)	12.6 (3.3 to 21.9)	0.7 (-5.2 to 3.8)	0.051
Week 24	34.0 (28.2 to 39.9)	24.0 (14.7 to 33.3)	3.1 (-1.8 to 8.0)	0.032
SF-36 MCS
Week 12	12.1 (5.7 to 18.6)	8.5 (−0.9 to 17.9)	1.5 (−5.4 to 8.4)	0.665
Week 24	29.8 (23.3 to 36.3)	16.7 (7.3 to 26.1)	6.7 (0.8 to 12.5)^#	0.028
PSQI
Week 12	−2.8 (−4.7 to −0.9)	−2.7 (−4.6 to −0.9)	−0.6 (−2.2 to 1.0)	0.451
Week 24	−3.1 (−5.2 to −1.0)	−3.9 (−5.9 to −1.9)	0.3 (−1.3 to −2.0)	0.681

The quality of life was assessed by the SF-36 and PSQI from physical function, mental health, and sleep quality. 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-36, Short-Form Health Survey; PCS, physical component summary; MCS, mental component summary; PSQI, Pittsburgh Sleep Quality Index.
