Structural Integration is a scientifically validated method of restructuring the body through movement and touch. It was founded by Dr. Ida P. Rolf, who developed a system of organizing the body, enabling it to let go of holding patterns and habitual stress.

Structural Integration (SI), which is sometimes called Rolfing, considers gravity, physical structure, and individual habits (such as work-related posture and physical activities) to bring a person into his or her vertical alignment.
