Inequalities in illness, service provision, and outcomes are well documented in the Nordic universal welfare state. The ways in which inequalities are produced during illness recovery trajectories remain largely unknown. Long-term brain injury rehabilitation in this context provides a window into veiled aspects of inequality and the underlying mechanisms. We examine inequality empirically by combing framing field structures with the classed abilities of families to mobilise capital after a severe acquired brain injury (severe ABI). Using a Bourdieuan theoretical framework, informed by the concepts of field, doxa, cultural health capital (CHC), and rehabilitation capital (RC), we designed a longitudinal case study encompassing professional records, observations, and interviews that tracked and analysed subjects' trajectories. We found that families' consistent accumulation and conversion of capital was crucial after a severe ABI because of the multifaceted rehabilitation process involving many different field specific agendas and doxas. This study supplements previous concepts (CHC and RC) developed in a health care context by including other rehabilitation contexts. These disparities in forms of capital amongst social classes result in winners and losers and were reflected in the rehabilitation trajectories of the young adults, characterised by continuity on one extreme and broken trajectories on the other.
