Behavior of sacroiliac joint mobility in individuals subjected to osteopathic manipulation of the ilium

Abstract

Introduction: Dysfunction sacroiliac joint (SIJ) is a frequent problem in patients with low back pain and may cause functional limitations. Pain prevalence in SIJ ranges from 15 to 30% in patients with low back pain, based on clinical assessments. The maneuver
High Speed and Low Amplitude (HVLA) is an osteopathic maneuver that can be used for standardization of this functional change. Objective: To analyze through the Kinematic Analysis the possible changes in ASI movement amplitude in the osteopathic pre and post-manipulation of the ilium. Methods: 30 healthy men participated in this quasi-experimental study. Their ages were between 18 and 35 years, and they have been allocated in two groups: placebo and manipulated. For each of them, markers were placed in 7 benchmarks (PEI, S2, greater trochanter, femoral condyle), which were captured for Kinematic Analysis while the participant performed the hip flexion movement. After a Kinematic Analysis evaluation, the manipulated group underwent a HVLA thrust manipulation anterior iliac, while the placebo group was only put into tension without the final thrust. A new Kinematic Analysis evaluation was performed to compare the amplitude of the SIJ pre- and post-manipulation. The samplecharacterization data was analyzed through descriptive statistics. Pearson correlation test was used to analysis the possible correlations between weight/age with a mobility SIJ. The level of significance was 95% (p <0.05) for all analytical statistics tests. Results: Increased mobility of SIJ manipulated side and a decrease in SIJ contralateral, both in the placebo group and manipulated group, however no significant statistics. Through the Fisher's Exact Test, it was found a statistically significant association between mobility and standing flexion test (SFT) in both groups (p = 0.001). There were no statistically significant associations between mobility ASI with the sitting
flexion test (SitFT) and also between weight, age and mobility SIJ. Conclusion: It is concluded that there was no significant difference mobility after an iliac HVLA thrust manipulation in healthy subjects. New studies are suggested with manipulation in bilateral healthy in woman and in symptomatic subjects.
