Sensory Attachment Intervention Sensory Attachment Intervention (SAI) was developed in recognition that trauma influences the way individuals process sensory information and how they relate to others i.e. they organise around danger. Need to consider what are the core fears; Sensory - fear of sensation, or fear arising from the incapacity to organise sensation for use, Attachment - fear of rejection, fear of separation.  Sensory Attachment Intervention is an integrative treatment approach for children, young people, and adults who have experienced trauma and abuse.
• The focus of therapy to enable the process of self-regulation and co-regulation by embedding regulation in daily living.
• It primarily draws from the Theories of Ayres’ Sensory Integration, Crittenden’s Dynamic Maturation Model of Attachment, Developmental Trauma, and Porges’ Polyvagal Theory. 
• SAI - Focuses on enabling self regulation & co-regulation.
• Two Key Relationships; Relationship with others in particular attachment figures, Relationship with the Environment. Sensory Attachment Intervention
• All information is sensory.
• Sensory processing generates representations of attachment relationships, of the physical self (body scheme) and of the physical environment.
• Perception of sensory and attachment experiences disposes the individual to behave in a particular way, and to adopt strategic behaviours for the purposes of engaging with others and with the environment (home, school, work place, leisure).
• What is the intention/function of the behaviour? Intervention looks beyond behaviours.

Level 4 Organisation 

Children and adults are assisted to explore their 'Just Right State' sensations and thus explore how they impact on perceptions, thoughts. Via use of exercises on an exercise ball, food and games children are aided in exploration.
