This study examines the quality of life (QOL) of community living elderly people aged 55-74 with chronic, episodic or sporadic pain in the hip or knee and of a reference group without pain (total n = 306). Firstly, it was hypothesized that the experienced QOL is lower in people with more chronic pain. Secondly, the potential mediating and moderating roles(More)
BACKGROUND Identification of older persons at risk for the loss of independence, onset of (co)-morbidity or functional limitations through screening/assessment is of interest for the public health-care system. To date several different measurement instruments for overall physical function are frequently used in practice, but little information about their(More)
OBJECTIVE To systematically review the effect of physical exercise on cognition in older adults with and without cognitive decline. DATA SOURCES : Randomized controlled trials were identified by literature searches in PubMed, EMBASE, CENTRAL, PsycINFO, and AgeLine. STUDY SELECTION Papers were included on the basis of predefined inclusion criteria. (More)
PURPOSE To review recently published studies on the reproducibility, validity, and feasibility of motion sensors used to assess physical activity in healthy children and adolescents (2-18 yr). METHODS On October 2004, a systematic literature search in PubMed, EMBASE, and PsycINFO was performed. This search has been updated on October 2007. In this update,(More)
