Inclusion criteria

Inclusion criteria: Inclusion criteria for pregnant women with pelvic pain: 1. Pregnant women with pelvic pain, between the ages of 25 and 35 who are experiencing their first pregnancy. 2. Pelvic pain in these women, should be from 18 weeks onwards, with pain in the sacroiliac joints and/or pubic area. 3. The result of two tests from the mentioned tests (posterior pelvic pain stimulation test, Patrick Faber's test, Trendelenburg test, and active straight leg test) should be positive during the clinical examination. 4. According to the VAS assessment, the rate of pelvic pain in pregnant women should be higher than 3 out of10. Inclusion criteria for healthy pregnant women without pelvic pain: 1. Healthy pregnant women between the ages of 25 and 35 who are experiencing their first pregnancy.

Exclusion criteria

Exclusion criteria: Exclusion criteria for pregnant women with pelvic pain: 1. Pelvic pain and low back pain before pregnancy. 2. Red flags symptoms 3. Multiple pregnancies 4. Pregnancies with complications and other diseases such as systemic diseases. Exclusion criteria for healthy pregnant women without pelvic pain: 1. Pelvic pain and low back pain before and after pregnancy. 2. During the clinical examination, even if one of the tests for posterior pelvic pain stimulation, Patrick Fabers, the modified Trendelenburg test and, the active straight leg test are positive. 3. Red flag symptoms. 4. Multiple pregnancies. 5. Pregnancies with complications and other diseases such as systemic diseases.

Design outcomes

Primary

MeasureTime frame
Surface electromyography. Timepoint: In the first session, all participants participate in an electromyographic evaluation once. In the same session, after wearing the pelvic belt, the intervention group performs an electromyography evaluation. In the intervention group, the pelvic belt is worn during awakening and during the day for two hours and thirty minutes, for 14 days. The control group (receiving the manual) and the intervention group perform electromyographic evaluations on day 14. Method of measurement: The muscles are evaluated in a standing position, through superficial electrodes in the distal and proximal pelvic muscles (posterior thigh muscles (long biceps and tendon muscle), gluteus maximus, multifidus muscles (level two L1 and L5) and, internal oblique muscles are examined. The signals recorded by the kinesiological EMG ME 6000 electromyography device are stored on the laptop through the Mega Win software. After deleting the beginning and end of the recorded values, the duration is 10 seconds out of 20 seconds. Information processing is done by MATLAB software.;(Intensity of pain) Visual Analogue Scale. Timepoint: In the first session, all participants will be assessed for pain intensity once. In the same session again, after wearing the pelvic belt, the intervention group is evaluated. In the intervention group, the pelvic belt is worn during awakening and during the day for two hours and thirty minutes, for 14 days. The control group (receiving the manual) and the intervention group perform electromyographic evaluations on day 14. Method of measurement: It consists of a 10 cm line, which is placed horizontally on a piece of paper. A dot is placed on it at each end. One point of this line indicates "no pain", and the other point indicates "maximum perceived pain intensity". Individuals assess their perceived pain intensity by marking on this horizontal scale line. The distance from the point of no pain to this person-marked mark is measured by a ru
