Pilates training can be an excellent way to achieve the postural re-education and muscle-balancing necessary to recover from the side effects of breast cancer treatment. Pilates can help alleviate pain from breast cancer operative procedures, restore joint mobility and tissue integrity, and help regain lost strength. Most importantly, Pilates can be a gateway for a true “Return to Life” for many women, as the title of Joseph Pilates’ popular book states. However, Pilates instructors should be on the lookout for some often coincident injuries that will require additional special knowledge about the shoulder complex in order to work safely and effectively with the growing population of breast cancer survivors.
