BACKGROUND The sacroiliac joint is a widely described source of low back pain. Therapeutic approaches to relieve pain include the application of pelvic belts. However, the effects of pelvic belts on sacroiliac joint ligaments as potential pain generators are mostly unknown. OBJECTIVES The aim of our study was to analyze the influence of pelvic belts on ligament load by means of a computer model. STUDY DESIGN Experimental computer study using a finite element method. METHODS A computer…

Pelvic Belt Effects on Pelvic Morphometry, Muscle Activity and Body Balance in Patients with Sacroiliac Joint Dysfunction
The potential pain-decreasing effects of pelvic belts could not be attributed to altered muscle activity, pelvic morphometry or body balance in a static short-term application and long-term belt effects will be of prospective interest.
Pelvic orthosis effects on posterior pelvis kinematics An in-vitro biomechanical study
Using a physiologic mode of load application gives novel insights into the potential effects of pelvic orthoses, including a vast increase in axial rotation accompanied by increased inferior translation of the sacrum relative to the ilium in the SIJ.
Three-Dimensional Finite Element Analysis of the Effects of Ligaments on Human Sacroiliac Joint and Pelvis in Two Different Positions.
The location of stress concentration and displacement distribution of pelvic bone are closely resembled previous research results in two different positions and may provide beneficial information and theoretical models for clinical research of pelvic fracture, joint movement and ligament functional injuries.
Physiological in vitro sacroiliac joint motion: a study on three‐dimensional posterior pelvic ring kinematics
Evidence of different SIJ motions than reported previously when exerted by physiological loading is provided, underlines the relevance of the lumbosacral transition when considering the overall motion of theLumbopelvis, and how relatively little the other segments contribute to overall motion.
The extent of ligament injury and its influence on pelvic stability following type II anteroposterior compression pelvic injuries––A computer study to gain insight into open book trauma
The sacrospinous ligament appears to be of minor significance in APCII but plays an important role in vertical stabilization, and the interosseous sacroiliac and sacrotuberous ligaments are likely responsible for reducing the symphysis and might serve as an indicator of vertical stability.
A finite element analysis of sacroiliac joint displacements and ligament strains in response to three manipulations
The three common manipulations all produced small displacements of the SIJ and different degrees of ligament strains, which might be the mechanism through which they relieve SIJ pain.
In Silico Pelvis and Sacroiliac Joint Motion: Refining a Model of the Human Osteoligamentous Pelvis for Assessing Physiological Load Deformation Using an Inverted Validation Approach
This study has used an inverted validation approach to refine an existing FE model, to give realistic and accurate load deformation data of the osteoligamentous pelvis and showed which variation in the outcomes of the models are attributed to altered material properties and models.
The effects of a pelvic belt on trunk and lower extremity muscles in the bridge position
The use of a pelvic compression belt with external pelvic compression might improve pelvic joint stability and alter neuromotor control of the lumbopelvic and thigh muscles.

Biomechanical model study of pelvic belt influence on muscle and ligament forces.
Does a pelvic belt influence sacroiliac joint laxity?
A Finite Element Analysis of Sacroiliac Joint Ligaments in Response to Different Loading Conditions
To characterize the sacroiliac ligament strains in response to flexion, extension, and axial rotation loads and quantify the changes in SIJ stress and angular displacement in Response to changes in ligament stiffness, a finite element analysis was utilizing a three-dimensional model constructed from computed tomography scans.
The mechanical effect of a pelvic belt in patients with pregnancy-related pelvic pain.
The effect of boundary condition on the biomechanics of a human pelvic joint under an axial compressive load: a three-dimensional finite element model.
Pelvic biomechanics is very dependent on the boundary condition in the finite element model, and taking sacrum and ilium as a whole, instead of sacroiliac and iliolumber ligaments, can influence the stress distribution on ilium and pubis bone vastly.
Novel Insights Into the Sacroiliac Joint Ligaments
The combined use of high-resolution MRI and thin slice plastination allows precise reconstructions of the SIJ ligaments, and the ASL and PSL parameters were larger in males, while the ISL parameterswere larger in females.
The sacroiliac joint: an overview of its anatomy, function and potential clinical implications
The sacrum, pelvis and spine, and the connections to the arms, legs and head, are functionally interrelated through muscular, fascial and ligamentous interconnections.
