Health promotion and prevention of functional decline among home dwelling adults and immediate onset of rehabilitation, can improve function, and reduce or delay need for home-based assistance and institution placement. In the coming years there will be a significant increase in number of persons in Norway that need interventions aiming at coping with everyday activities. Therefore there is a call for new models for early intervention and rehabilitation in order to give service to a larger amount of home living people. Reablement is a new and promising rehabilitation model which many Norwegian municipalities are implementing in order to meet current and future needs for municipal home-based services. However, very little research has been performed regarding the effectiveness of this intervention. This study aims at assessing the effectiveness of reablement in terms of daily functioning, health-related quality of life, coping, mental health and economic municipal costs.
