“…Among the mechanical factors predisposing a person to the described pathology, there should be included: disproportionate labor (i.e., heavier weight of the child in relation to the relatively narrow bone pelvis of the mother), the position of the fetus in the uterus, rapid and strong contractions during labor, a second labor period which is too long, the use of labor forceps, or a medical history of trauma in the pelvic area [ 13 ]. Additional factors that may have an influence on the occurrence of PSD are: degenerative changes in sacroiliac joints, rheumatoid arthritis, pain in the lumbosacral region of the spine, hormonal disorders, and psychosocial factors.…”
