The primary objective of this systematic review is to assess the efficacy of a range of physical therapy interventions for the management of PGP following pregnancy.

We will assess efficacy in terms of reduced pain, improved disability/functional status, improved overall health/health-related quality of life, and treatment success (participant-reported).

We will compare each intervention/modality of physical therapy considered as a relevant intervention in the treatment of pelvic girdle pain (PGP) after pregnancy to:

• no treatment;
• placebo/sham treatment; or
• conservative treatments not considered as physical therapy (such as acupuncture, cognitive-behavioral treatment etc.).

In subsequent investigations we will compare the efficacy of different physical therapy interventions/modalities when compared against each other (head-to-head comparison). We will do this for the same outcomes as above (reduced pain and disability and improved health-related quality of life).
