What this study adds: The same relationship of greater falls risk among aged care residents with intermediate ability also exists for other aspects of mobility including bed and chair mobility, dynamic standing balance, and ambulation. The Physical Mobility Scale can

be used to discriminate aged care residents who are most and least likely to fall. Evaluating the falls risk of residents in aged care facilities is complicated. Inconsistencies in the association between mobility impairment and Volasertib falls risk reported by past studies may be partially attributable to differences in the methods for measuring mobility. Measurement of mobility requires an understanding of the multiple components underpinning mobility. There are several components to consider, including bed mobility, sitting and standing balance, transfers, and ambulation. In addition, residents often require mobility aids and staff assistance to perform mobility tasks. Some studies have investigated the association between falls and a single mobility task, such as sit to stand (Kallin et al 2004,

Lord et al 2003), negotiation of stairs (Kallin et al 2002), or ambulation (French et al 2007, Maurer et al 2005). In comparison, the Physical Mobility Scale is a comprehensive, reliable and valid interval measure of resident mobility (Barker et al 2008, Nitz et al 2006, Pike and Landers 2010). It quantifies buy BVD-523 the amount of assistance and equipment an individual requires to safely perform nine mobility tasks ranging from bed almost mobility to standing balance (Nitz et al 2006). The investigation of the association between mobility impairment assessed using the Physical Mobility Scale and falls risk has not been reported previously. This study aimed to build on existing research by characterising the association between mobility impairment as measured by the Physical Mobility Scale and falls risk, for people living in residential aged care. Therefore the research questions for this study were: 1. What is the association between mobility and falls risk for people living in residential aged care? This study used a prospective cohort design to investigate

the association between falls risk and mobility impairment. Residents from six residential aged care facilities were invited to participate in the study. Facilities were identified through convenience sampling. After baseline assessment with the Physical Mobility Scale, participants were followed for six months to record the number of falls. Permanent high care (nursing home) and low care (hostel) residents were eligible for inclusion in the study if they had lived at the facility for longer than 12 months. The participating facilities were located in Queensland, Australia. The facilities provide accommodation, meals, clinical care, and social activities for people in their later stages of life. Participants were recruited by personal approach.
