The findings from the study show that: after 3 days of treatment, the mean pain point VAS of the study group (1.6 ± 0.9) was significantly lower than that of the control group (2.9 ± 0.7) (p < 0.05); the mean fundal height of the study group (10.4 ± 0.6 cm) was significantly lower than that of the control group (10.8 ± 0.7 cm) (p < 0.05); proportions of patients having good treatment outcomes of the study group (50%) were significantly higher than those of the control group (20%) (p < 0.05).
