This study investigated the relationship between @entity998 ( @entity998 ) and qualitative and quantitative postural control in @entity191 ( @entity191 ). Fifty-eight nondemented @entity191 @entity1 were studied along with age-matched healthy controls. The degree of @entity998 was estimated using the Activities-specific Balance Confidence scale. Qualitative postural control was evaluated using a component of the Unified @entity191 Rating Scale. Postural control was quantified, using centre of pressure measures obtained from a force plate, for eight standing balance tests of different challenges. The results showed that @entity998 was more evident for @entity191 @entity1 when compared with healthy individuals of similar age. Furthermore, @entity998 was significantly associated with a qualitative estimate of postural control in @entity191 ; individuals with @entity191 who had a greater degree of @entity73 reported greater @entity998 . The results also showed that an estimate of @entity998 may help to explain quantitative postural instability in @entity191 . @entity998 , when coupled with a qualitative estimate of postural control, was able to explain a greater amount of variation in quantitative balance performance for five of the eight balance tests. When considered independently, the qualitative measure of postural control, in general, could not well predict quantitative balance performance. The greater degree of @entity998 and its possible association with altered postural control suggests that @entity998 should be considered as an important, independent risk factor in the assessment and treatment of postural instability in @entity1 with @entity191 .
