Questionnaires completed by 400 expectant mothers revealed that 75.3% had experienced back pain at some point in their pregnancy, particularly in the lumbar region during the third trimester. Nearly half of the women in the study (45.7%) reported that their back pain limited their daily activities. Doctors of chiropractic commonly treat low back pain arising from pregnancy with a combination of manual therapies and specific exercises. Pain Management Nursing, June 2020
