Pain Medicine -- 2014, v 15, n 9, p. 1455-1463Summary: Objective. This study aims to evaluate the immediate effect of a global pelvic manipulation (GPM) technique, bilaterally applied, on low back pelvic pain in women with primary dysmenorrhea (PD).
Design. A prospective, randomized, double-blind, controlled trial.
Setting. Faculty of Nursing, Physiotherapy and Podiatry. University of Sevilla, Spain.
Methods. The sample group included 40 women (30 ± 6.10 years) that were divided into an experimental group (EG) (N = 20) who underwent a bilateral GPM technique and a control group (CG) (N = 20) who underwent a sham (placebo) intervention. Evaluations were made of self-reported low back pelvic pain (visual analog scale), pressure pain threshold (PPT) in sacroiliac joints (SIJs), and the endogenous response of the organism to pain following catecholamines and serotonin release in blood levels.
Results. The intragroup comparison showed a significant improvement in the EG in the self-perceived low back pelvic pain (P = 0.003) and in the mechanosensitivity in both SIJs (P = 0.001). In the betweengroup comparison, there was a decrease in pain
perception (P = 0.004; F(1,38) = 9.62; R2 = 0.20) and an increase in the PPT of both SIJs, in the right side (P = 0.001; F(1,38) = 21.29; R2 = 0.35) and in the left side (P = 0.001; F(1,38) = 20.63; R2 = 0.35). There were no intergroup differences for catecholamines plasma levels (adrenaline P = 0.123; noradrenaline P = 0.281; dopamine P = 0.173), but there were for serotonin
levels (P = 0.045; F(1,38) = 4.296; R2 = 0.10).
Conclusion. The bilateral GPM technique improves in a short term the self-perceived low back pelvic pain, the PPT in both SIJs, and the serotonin levels in women with PD. It shows no significant differences with a sham intervention in catecholamines
plasma levels.
