Global Changes Associated With Sacroiliac Joint Dysfunction

Summary

* Summary Sacroiliac joint dysfunction (ASI) is an alteration in the normal biomechanics of the joint, which leads to hypomobility or hypermobility of that joint. It is one of the most common causes of misdiagnosis in low back pain and when not treated correctly, it often evolves into chronic pain (30% to 42%) and disability. Manipulating the dysfunctional ASI appears to result in benefits and significantly positive changes at various levels, in all segments of the human body. With this investigation, we intend to clarify and deepen the possible correlation between the changes that normally accompany this dysfunction, as well as its possible reversibility with its normalization.
* Objectives

The investigators will essentially have two main objectives:

1. Mapping of the most evident symptomatic changes, when sacroiliac joint dysfunction is present, in terms of pain and muscle tone;
2. To try to understand the immediate, global and immediate effect of ASI manipulation.

* Study design Quantitative, with experimental study design, with the sample comprising individuals with SIJ dysfunction, where all participants will be randomly allocated to the experimental, control and sham groups. It will be carried out at the University of Aveiro facilities.

Initially, we will assess the participants with sacroiliac dysfunction. The experimental will be manipulated, the control group will do nothing, and the sham group will be submitted to a hypothetical manipulation (sham manipulation). Consequently, the patients will be assessed again, measuring the subjective and objective degree of pain and muscle tone.

\- Material and methods

We will make use of:

* Standing flexion test;
* Sitting Flexion Test;
* Faber Test;
* EVA , to subjectively assess pain;
* Pressure algometer, to objectively assess pain ;
* MyotonPro, to assess muscle tone;

Conditions

• Sacroiliac Dysfunction

Interventions

OTHER

Manual manipulation

The participants will receive one session of manipulation if in the experimental group. It should be mentioned that the technique will be carried out by a physiotherapist with a history of more than 10 years of manual therapy. For instance, to correct right anterior innominate rotation, the participant will be made to lie on the side so that the affected side is upward. The physiotherapist will stand in front of the participant; first we will put their shoulders, pelvis and lower limbs in neutral position and place the right hand on the anterior superior iliac spine (ASIS) and the left hand on the ischium tuberosity and with a rotational movement of the hands, the physiotherapist will rotate the ilium posteriorly. At the end of the range, we will replace the position of hands and place the left forearm on the ischium tuberosity and place the right hand on the upper participant's shoulder and will move it toward the bed at the end of the range in exhalation a thrust will be executed.

At the end of the range, we will replace the position of hands and place the left forearm on the ischium tuberosity and place the right hand on the upper participant's shoulder and will move it toward the bed at the end of the range in exhalation, the physiotherapist will pretend to execute a thrust.
