Comparison of BI score between the two groups. Note: the abscissa represented before and after treatment, while the ordinate represented BI score, points. The BI scores in the experimental group before and after treatment were 61.23 ± 6.33 points and 89.12 ± 10.15 points, respectively. The BI scores in the control group before and after treatment were 60.88 ± 5.37 points and 77.77 ± 9.89 points, respectively. indicated that there were significant differences in BI scores in the experimental group before and after treatment (t = 13.189,  ≤ 0.01). indicated that there were significant differences in BI scores in the control group before and after treatment (t = 8.220,  ≤ 0.01). indicated that there were significant differences in BI scores between the two groups after treatment (t = 4.454,  ≤ 0.01).
