 Structural Integration SI is an alternative method of manual therapy and somato-sensory training that purports to improve the biomechanical functioning of the body as a whole rather than to focus on the treatment of specific symptoms. SI is delivered in a series of ten treatments, referred to as the Ten Series, each of approximately one hour in duration. The Ten Series protocol includes manipulation of all major joints and anatomical segments. Each of the ten sessions aims to achieve a different, specified set of biomechanical changes which are regarded as contributing to the progressive approximation of specific ideals of posture and movement.
