People with ABI contend that it is not the degree of participation that matters, but the quality of participation. They describe meaningful participation in terms of taking part, giving something and being someone. A model was constructed based on the experiences, which includes personal and environmental factors that, in interaction, may influence participation: participation is influenced by the process of recovery, support and treatment, the environment and society and communication and interaction. The study resulted in an overview of actions like continual care that may improve the participation of people with ABI.

The patients' research agenda can be used to match research with patients' needs and to adapt the clinical support of professionals to patients' wishes.

The QoL of patients with PD is influenced by many interacting factors related to their health, personal relations, care, communication and society. To improve the QoL and care for persons with PD, all factors should be taken into account. Person-centred care recognizes the uniqueness and capabilities of patients with PD.
