So Every BODY Can Move is a national movement grounded in the belief that movement is medicine—and that physical activity is a right, not a privilege. The initiative works to change outdated policies that deny access to prosthetic and orthotic care for sport and exercise by mobilizing advocates to drive legislative change at the state level. With a goal of achieving coverage in 28 states by the 2028 LA Paralympics, the movement aims to lay the groundwork for federal reform.
