Introduction: During pregnancy, a woman's body goes through many changes, and lower back and pelvic pain are common and may persist after pregnancy. Although the literature point physical therapy as an effective therapeutic tool, there are few studies on the effects of physical therapy intervention through exercises for this purpose. Objective: To perform a systematic review on the use of Physiotherapy, through therapeutic exercises, for the prevention and treatment of pregnancy low back and pelvic pain. Methods: A systematic search for randomized trials (RCTs) was conducted on the databases PubMed, PEDro, Cochrane, EMBASE, LILACS and Periódicos Capes. There was no date or language restriction. The terms included in the search were: "pregnancy", "low back pain", "pelvic pain", "exercise therapy" and their descriptors in Portuguese. Methodological quality was assessed using the PEDro scale and a descriptive analysis of the studies was performed. Results: Eight studies, including 1781 pregnant women, were selected. Among them, one study addressed the issue of low back pain, two focused on pelvic pain and five on low back and/or pelvic pain. Seven studies presented high methodological quality, and only one study had low methodological quality. Limited evidence on low back pain was found, and conflicting evidence on pelvic pain, and low and/or pelvic pain. Conclusion: RCTs on the subject are scarce and heterogeneous, making it impossible to reach a consensus
