Structural Integration is a process of reintegration of the body through movement and touch. It systematically releases patterns of stress and impared function. The priamary relationship between gravity and the human body

It was Dr. Rolf's theory that the cause of human discomfort, both physical and emotional may lie in our internal connective tissue and the relationship it has with the earth’s gravitational field.

There is, she argued, an optimal, more natural alignment for each of us – an easier interaction between self and gravity. When through external factors this alignment is lost, it causes internal stress that can result in real discomfort. Prevent or correct the misalignment and you may eliminate or limit the stress. This is at the heart of Rolfing.

Linking all internal structures within the human frame is the fascial web. This plastic connective tisse unites the structure of the inner form and divides its individual functioning units.

Fascia is constantly changing and adapting in response to demands placed on an individual's body. It reacts to particular physical damage – to a joint for example – by producing extra material to enhance stability and support. However, it can produce more than is necessary. In time, rather than stabilizing movement it can actually reduce mobility, leading to a changed postural position and altered patterns of movement.
