Abstract

Abstract:

Objective

To assess the effect of pelvic floor muscle training by transperineal sonography, so as to provide important guidance for the recovery of postpartum pelvic floor function.

Methods

The clinical data of 30 women with pelvic floor muscle training in our hospital and 30 cases without pelvic muscle training were analyzed retrospectively. The basic structures of pelvic floor in the two groups were observed by transperineal sonography, and the parameters including the bladder neck to the public symphysis edge distance (Dr, Ds), posterior urethrovesical angel (βr, βs) and bladder rotation angel (γ) were measured in quiet state and pressure state (Valsalva operation). These parameters including the age, Dr, Ds, βr, βs and γ were compared between the research group and the control group by t-text of group design. Those parameters were compared between two groups after training for fourteen weeks and for six weeks by t-text of matching design.

Results

(1) βr, βs and γ in research group were both lower than those in control group (t=3.17, 3.83 and 2.44, P<0.05) after training for fourteen weeks but Dr and Ds were both higher than those in control group (t=4.63 and 2.14, P<0.05). The difference of Dr, Ds, βr, βs and γ between research group and control group were not statistically significant (t=1.30, 0.40, 0.52, 0.87 and 1.21, P>0.05) after training for six weeks. (2) βr, βs and γ showed a gradual decrease after training for six weeks and fourteen weeks (t=11.53, 4.84 and 4.26, P<0.05) in research group, but Dr and Ds showed a gradual increase (t=11.43 and 10.00, P<0.05). βr, βs and γ showed no statistically significant in control group (t=1.94, 1.96 and 1.87, P>0.05), but Dr and Ds showed a gradual increase after the treatment for six and fourteen weeks (t=11.43 and 10.00, P<0.05).

Conclusions

The basic structures and function of pelvic floor can be gradually improved by pelvic floor muscle training. Transperineal sonography can objectively assess the effect of pelvic floor muscle training and provide important basis for detecting pelvic floor dysfunction earlier and postpartum recovery.
