Rolfing or structural integration is a system of soft tissue manipulation, with the objective of realigning the boy structurally and harmonizing its fundamental movement patterns in relation to gravity. The system was founded by Ida Pauline Rolf. Practitioners of Rolfing believe it to enhance vitality and well-being, and claim that after sessions, many clients stand up straighter, gain in height, and that soft-tissue bodily asymmetries tend to disappear.[neutrality disputed][who?] Rolfing is in some ways similar to deep tissue massage (see especially Myofascial Release), however, practitioners claim that Rolfing's attention to the balance of the body in gravity sets the practice apart.[neutrality disputed][who?]
