This chapter 'maps out the terrain', provide the reader with a corporeal and embodied introduction to the core issues on which this social scientific theorisation of acquired brain injury (ABI) is based. It explains the author's sociological conceptual framework that he outlined in the Introduction to help disentangle his own rehabilitative experiences. This provides the reader with further knowledge of the sociological tools that are used to make sense of the lives of the participants and presents author's personal experiences of identity (re)construction. His experiences suggest that a 'rhizomatic' and 'nomadic' approach to rehabilitation and identity (re)construction that views identity in a fluid and malleable way is appropriate. He uses his social scientific analytical framework to explore the neurological rehabilitation process after ABI through the lens of the ABI survivor. An acceptance of the need for 'patient centred care' provides a firm justification for the gathering of ABI survivor experiences.
