Previous research on intensive care unit (ICU) survivors shows that rehabilitation is challenging, because of patients experiences of disease related problems both under and after treatment. Approximately 20 % of patients die within hospital, up to 80% suffer from hallucinations and nightmares, deal with paranoiac experiences, chronic pain and other symptoms and disability (Angus et al 2004; De Letter et al 2001; Ely et al 2001; Nelson et al 2006; Van den Berghe et al 2001; Van den Berghe et al 2003) . A recent study shows that 28% of intensive care survivors have chronic pain that reduce their health related quality of life (Boyle et al 2004).
