“…Moreover, our findings showed an improvement in dual-task abilities, common tasks required during everyday life. 54,55 Similarly, Hamacher et al 35 showed that dance activity significantly increases multitasking abilities compared with health-related exercise, highlighting the benefit of multi-tasking exercises 16 such as dance activity to improve motor-cognitive dual-task performance. Indeed, dance may be considered a rhythmic activity that requires multiple physical and cognitive elements.…”

“…This implies an inverse relationship between the level of concern and activity function, as well as activity performance [16]. The current evidence comes essentially from studies that used measures of walking performance in clinical/laboratory settings [14,15], and the collected self-reported information about the level of mobility and activities of daily living rather than objective measures [17]. There is a lack of knowledge regarding the association between very low concern about falling and objective features of PA behavior recorded in daily life settings among well-functioning communitydwelling older people.…”

“…This decreased complexity in the output of the locomotor system has been postulated to arise from the degradation in the interactions between various systems such as, for example, the musculoskeletal, proprioceptive, and psycho-cognitive [7,8,10,11]. The concern about falling and the perceived fall risk are controlled by psycho-cognitive processes that mediate the individual's confidence and behavior to carry out specific activities, particularly in challenging conditions [14,15]. This implies an inverse relationship between the level of concern and activity function, as well as activity performance [16].…”

Concern about Falling and Complexity of Free-Living Physical Activity Patterns in Well-Functioning Older Adults

Background: Fall-related psychological concerns are common among older adults, potentially contributing to functional decline as well as to restriction of activities and social participation. To effectively prevent such negative consequences, it is important to understand how even very low concern about falling could affect physical activity behavior in everyday life. We hypothesized that concern about falling is associated with a reduction in diversity, dynamics, and performance of daily activities, and that these features can be comprehensively quantified in terms of complexity of physical activity patterns. Methods: A sample of 40 community-dwelling older adults were assessed for concern about falling using the Falls Efficacy Scale-International (FES-I). Free-living physical activity was assessed using a set of metrics derived from data recorded with a chest-worn tri-axial accelerometer. The devised metrics characterized physical activity behavior in terms of endurance (total locomotion time, longest locomotion period, usual walking cadence), performance (cadence of longest locomotion period, locomotion periods with at least 30 steps and 100 steps/min), and complexity of physical activity patterns. Complexity was quantified according to variations in type, intensity, and duration of activities, and was considered as an adaptive response to environmental exigencies over the course of the day. Results: Based on FES-I score, participants were classified into two groups: not concerned at all/fully confident (n = 25) and concerned/less confident (n = 15). Demographic and health-related variables did not differ significantly between groups. Comparison of physical activity behavior indicated no significant differences for endurance-related metrics. In contrast, performance and complexity metrics were significantly lower in the less confident group compared to the fully confident group. Among all metrics, complexity of physical activity patterns appeared as the most discriminative feature between fully confident and less confident participants (p = 0.001, non-parametric Cliff’s delta effect size = 0.63). Conclusions: These results extend our understanding of the interplay between low concern about falling and physical activity behavior of community-dwelling older persons in their everyday life context. This information could serve to better design and evaluate personalized intervention programs in future prospective studies.

“…The mobility tasks, such as stepping in various directions in the case of FSST, are often associated with one or even more additional activities, such as talking or paying attention to the environment [17]. These additional activities might lead to increased variabilities in a range of spatio-temporal stepping parameters [18].…”

Poor balance control and falls are big issues for older adults that due to aging decline have a lower postural balance and directional control in balance performance than younger age groups. The four square step test (FSST) was developed to evaluate rapid stepping that is often required when changing direction and avoiding obstacles while walking. However, previous researchers used only the total time as the assessment in the test. The aim of this paper is to objectively quantify the sequence and direction of the steps in FSST, by using two inertial sensors placed on both feet. An algorithm was developed to automatically segment the steps performed during the test, and calculate the stepping direction from the linear velocity of the foot. Experiments were conducted with 100 Japanese healthy older adults, where sensor data and video of 20 subjects were randomly subtracted for algorithm verification. The results showed that the algorithm succeeded for 71.7% trials in recognizing both the step sequence and step direction in FSST, while 90.2% of the detection failure could be excluded with an auto verification method.
