由表2可知，两组患者治疗前BBS评分经t检验，无统计学意义(P＞0．0

Table 2 shows that two groups of patients before treatment BBS rates by t test, no statistically significant (P> 0.05), two groups of patients before treatment described balanced distribution rates comparable BBS, BBS score two groups after treatment significantly improved compared to before treatment, there is statistically significant (P <0.01), and the degree of improvement in patients with BBS rates treatment group than the control group, statistically significant (P <0.05).

As can be seen from Table 2, the pre-treatment BBS score of the two groups of patients was t-tested and not statistically significant (P. 0. 05), show that the two groups of patients before treatment of the ratio of BBS score is comparable, after treatment in two groups of patients BBS score compared with pre-treatment significantly improved, statistically significant (P 0. 01), and the treatment group of patients BBS score significantly better than the control group, there is a statistical lym (P. 0. 05)。

It can be seen from table 2 that there is no statistical significance (P > 0.05) in BBS score of the two groups before treatment through t-test, indicating that the distribution of BBS score of the two groups before treatment is balanced and comparable, and the BBS score of the two groups after treatment is significantly higher than that before treatment, with statistical significance (P < 0.01), and the BBS score of the treatment group is significantly higher than that of the control group, with statistical significance (P < 0.05) 。<br>
