Abstrakt: Background: Concern about falling is reportedly related to mobility and balance in older adults. While increased concern about falling may be directly related to balance deficits, establishing a causal relationship remains limited. This study aimed to investigate whether concern about falling affects threat-induced changes in emotions and postural control in older adults.
Research Question: How does concern about falling affect threat-induced changes in emotions and postural control among older adults?
Methods: Sixty-two older adults (age; 78.8 ± 5.7 years, height; 152.7 ± 6.3 cm) were exposed to height-related fear while standing, leaning forward, and leaning backward on the floor and a higher surface. The mean position, root mean square, and mean velocity of the center of pressure (COP) displacement were measured during the standing task, as well as the forward and backward limits of stability (LOS) tasks. The degree of self-reported fear of falling (FoF) was also obtained during the standing and LOS tasks. The participants were categorized into lower and higher concerns about falling based on the short form of the Falls Efficacy Scale International (FESI).
Results: Lower and higher concern about falling groups scored 10.2 ± 2.2 and 17.3 ± 3.3 in the short FESI. Both groups experienced increased FoF during the standing and forward LOS tasks on a higher surface. Leaning away from the edge of the surface resulted in increased COP velocity, decreased COP amplitude while standing, and decreased forward LOS. Participants with higher concern about falling had increased FoF during the backward LOS task and decreased backward LOS on a higher surface, while those with lower concern about falling did not.
Significance: Concern about falling can directly affect emotions and balance control owing to the occurrence of threat-related changes.
