ANALYSIS OF BELT IN PREGNANT WOMEN SUFFERING FROM PELVIC GIRDLE PAIN

Half of the pregnant women suffer from pelvic girdle pain. The most common cause of sick leave during pregnancy is pelvic girdle pain which touch approximately 37%. PGP is defined as posterior region of the pelvis, defined as “a pain between the posterior iliac crest and the gluteal fold, particularly in the vicinity of the sacroiliac joint (SIJ). The pain may radiate in the posterior thigh and can also occur in conjunction with/or separately of pain in the symphysis”. In bipedal position endurance capacity while walking is impaired. The “self-locking” mechanism is a model where shear in the SIJ is prevented by increased friction due to a combination of two factors: the first is a specific anatomic arrangement that increases the friction coefficient (form closure) and the second is the tension of muscles and ligaments crossing the SIJ that lead to higher friction and hence stiffness. The literature tends to favor flexible belts that seem to have a greater impact on pain. However, although no significant difference between groups was seen, the narrow flexible belt allowed a significant decrease of SIJ and global pain, which tends to support previous finding s. After the use of the broader and more rigid belt a decrease in back pain was found, suggesting the possibility of a differential benefit of both types of belts
