Abstract

The aim of the present study was to determine whether force plate variables in single- and dual-task situations are able to predict the risk of multiple falls in a community-dwelling elderly population. Two hundred and seventy elderly persons (225 females, 45 males; age, 73+/-7 years) performed balance assessment with and without vision. Seven force plate variables were assessed to predict the risk of multiple falls; maximum displacement in the anteroposterior and medial-lateral directions (Max-AP, Max-ML), mean displacement in the medial-lateral direction (MML), the root mean square amplitude in anteroposterior and medial-lateral directions (RMS-AP, RMS-ML), the average speed of displacement (V), and the area of the 95th percentile ellipse (AoE). Falls were prospectively recorded during the following year. A total of 437 registered falls occurred during monitoring period. The force plate variable RMS-ML in the single-task condition (odds ratio, 21.8) predicted multiple falls together with the following covariables: history of multiple falls (odds ratio, 5.6), use of medications (fall-risk medications or multiple medicine use; odds ratio, 2.3), and gender (odds ratio, 0.34). Multiple fallers had a narrower stance width than non-fallers.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
