Values are means with means ± SD or the 95% confidence (CI). M1: measurements were obtained at baseline; M2: immediately after the last intervention; M3: one month after the last intervention; M4: six months after the last intervention.
The VAS scores means at different timepoints between two groups were analyzed by repeated measures analysis of variance. Within-subjects effects tests of different timepoints means, , . Between-subjects effects tests of different group means, , . The C-SFODI means at different timepoints between two groups were analyzed by repeated measures analysis of variance. Within-subjects effects tests of different timepoints means, , . Between-subjects effects tests of different group means, , .
values were calculated with independent-samples -test for mean change from baseline between two groups.
Visual analogue scale (VAS, scores range 0 to 100) with higher scores indicating greater pain.
The Chinese Short Form Oswestry Disability Index (C-SFODI, range 0 to 100%) consists of 9 questions, with higher percentage indicating more severe functional disability.
