[Case-control study on clinical effects of squeezing and clapping manipulation for treating the postpartum pubic...

To study the clinical effect of squeezing and clapping bone setting manipulation in treating the postpartum pubis symphysis separation.

From June 2015 to March 2017, 80 patients with postpartum pubic symphysis separation were randomly divided into treatment group and control group, 40 patients in each group. In treatment group, the patients' reproductive age ranged from 26 to 40 years old with an average of (30.61±5.94) years old and the neonatal weight ranged from 3.2 to 4.52 kg with an average of (3.59±0.13) kg. In control group, patients' reproductive age ranged from 22 to 37 years old with an average age of (27.51±4.57) years old and the neonatal weight ranged from 3 to 5.8 kg with an average of (3.81±0.63) kg. The patients in the treatment group were treated with the squeezing and clapping manipulation, once a week for 3 weeks. The patients in the control group were treated with pelvic bandage immobilization, and the immobilization of the pelvis was not less than 8 hours per day, 3 weeks for 1 course. The VAS pain score, Oswestry dysfunction index (ODI) and separation distance of pubis were clinical observed and evaluated on the first day of treatment, 1, 2, 3 weeks and 1 months after treatment.

The pubic symphysis VAS score was compared with that before treatment, in the treatment group, the difference was statistically significant at 1 week(P=0.013); the difference was statistically significant in the control group for 1 month (P=0.042). The two groups were less than those of the control group after treatment (P<0.05). The ODI score was compared with that before the treatment, in the treatment group, the difference was statistically significant at 1 week (P=0.009), the difference was statistically significant in the control group for 1 month(P=0.013), the two groups were less than those before treatment(P<0.05). The pubic symphysis distance was compared with that before treatment, the treatment group decreased significantly after treatment (P<0.05), there was no significant difference in the control group after treatment (P>0.05), the two groups were compared, the difference was statistically significant at first weeks(P=0.042) and third weeks (P=0.005).

The "squeezing and clapping" manipulation can quickly restore the distance between pubic symphysis separation, relieve local pain and improve lumbosacral function, and is better than pelvic bandage fixation treatment.
