Stroke is a common disease among older people. In Norway 60-70 000 people live with sequela after stroke. Depressive symptoms, anxiety and social isolation are occurring among 20 to 60 percent. Little is known about intervention for people with mild neurological symptoms who simultaneously perceive social isolation, depression and reduced satisfaction in their daily life after stroke. Lifestyle redesign (LR) is developed in the USA and is a health promoting group intervention programme with focus on the participants' exchange of experiences and involvement. The aim of the study is to evaluate the effect on thriving, activity and social participation of a group intervention program inspired by Lifestyle redesign for community dwelling persons with stroke. The study is conducted as a multicentre randomized controlled trial. Participants are recruited from five hospitals and the intervention is carried through at six to seven senior centres. The control group is offered a physical activity programme at the senior centre once a week. The intervention group is offered the same with the additional intervention programme also once a week. The study will contribute to knowledge whether this group intervention will promote social participation and thriving in daily life and prevent social isolation and depressive symptoms among community dwelling elders with stroke or TIA.
