Comparison of BBS scores. Note: The abscissa indicates pretreatment, 2 weeks of treatment, and 4 weeks of treatment; the ordinate indicates BBS score, points. The BBS scores of the conventional rehabilitation group before treatment, 2 weeks of treatment, and 4 weeks of treatment were 28.17 ± 2.55, 37.69 ± 2.12, and 45.30 ± 1.83, respectively. The BBS scores before treatment, at 2 weeks of treatment, and at 4 weeks of treatment in the MET group were 27.94 ± 2.48, 42.37 ± 2.26, and 48.65 ± 3.01, respectively. The BBS scores before treatment, at 2 weeks of treatment, and at 4 weeks of treatment in the Neurac group were 28.11 ± 2.35, 43.18 ± 2.42, and 49.04 ± 2.81, respectively. The BBS scores before, 2 weeks, and 4 weeks of treatment in the joint group were 27.61 ± 2.47, 48.16 ± 3.20, and 53.17 ± 1.87, respectively. ∗ and # indicate significant differences in the BBS scores between the conventional rehabilitation group and the joint group after 2 weeks of treatment and 4 weeks of treatment (t = 13.638, 15.039, P < 0.001). ∗∗ and ## indicate significant differences in the BBS scores between the MET group and the joint group after 2 weeks of treatment and 4 weeks of treatment (t = 7.390, 6.377, P < 0.001). ∗∗∗ and ### indicate significant differences in the BBS scores between the Neurac group and the joint group after 2 weeks of treatment and 4 weeks of treatment (t = 6.206, 6.118, P < 0.001).
