Group A get myofascial release on sacroiliac joint area for up to 600 seconds and total treatment sessions will be 12 in 4 weeks with support belt and a support belt should not be worn for longer than two to three hours at a time and it will be used 4 times a week.

The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").

The degree of functional disability was estimated using the Quebec scale, assessing 20 routine daily activities on a scale from 0 to 5 (0 = performing activities without difficulty, 1 = performing activities with minimal difficulty, 2 = performing activities with some difficulty, 3 = performing activities with moderate difficulties, 4 = performing activities with greater difficulty, 5 = inability to perform activities). The minimum score was 20 and the maximum score was 100. Higher scores correlate with greater disability.

The Pelvic Girdle Questionnaire (PGQ) was also applied. It was created to assess quality of life in patients with pelvic girdle pain during pregnancy and postpartum. It includes 25 questions, with 20 questions aiming to assess activity and 5 questions examining symptoms. Each question is scored on a 4-point Likert type scale (from 'no problem at all' [0 points] to 'to a large extent' [3 points]). The raw scores are then converted into a final score ranging from 0 to 100 (from best to worst outcomes). The questionnaire's reliability and validity in Turkish have been confirmed.
