Comparison of SDS scores of three groups of patients before and after intervention. There was no evident difference in SDS scores among the three groups before treatment. After treatment, SDS scores in experiment 1 group and experiment 2 group were significantly lower than those in routine rehabilitation group, and the improvement degree in experiment 2 group was better than that in experiment 1 group. Note: compared with routine rehabilitation group or comparison between the two groups, *P < 0.05, **P < 0.01.
