Pregnancy may impact the musculoskeletal apparatus of females through pregnancy-associated biomechanical, vascular, and hormonal changes. Pregnant females may complain of lumbopelvic pain, especially during their last trimester. This lumbopelvic pain can be the result of an enlarged uterus and unstable lumbopelvic joints.

Cesarean birth can affect the lumbopelvic biomechanics through its impact on the sacroiliac joints and the abdominal muscles. while vaginal birth can trigger lumbopelvic pain through its impact on the pelvic joints like the symphysis pubis and sacroiliacs.

When puerperium is finished, most of these pregnancy-related changes assume its prepregnant conditions.

Physiotherapists are responsible for providing PT care for women to improve their quality of life during the puerperium and even during the delayed postpartum interval.
