A systematic review of the current literature was conducted using portals such as the Physiotherapy Evidence Database (PEDro), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Ovid MEDLINE (1996 to April 2011), and Allied and Complementary Medicine (AMED) (1985 to April 2011). Databases were searched for relevant studies published up to April 2011. Participants in relevant studies were adults (b18 years of age) with a primary diagnosis of breast cancer at any point during the treatment of their disease.
