Functional stability limits have been proposed as a psychometric indicator of balance ability that could be used to incorporate stability constraints into ergonomic task analyses. Decreased functional stability limits are assumed to indicate decreased balance ability. These stability limits have been quantified for a young adult population. However, their validity as a measure of balance ability has not been investigated. The purpose of this study was to investigate the construct validity of functional stability limits as a measure of balance ability by quantifying the relationship between these stability limits and age and other more common measures of stability. As hypothesized, functional stability limits decreased with age, were positively related to performance on the Multi-Directional Reach Test, a valid indicator of fall risk for the elderly, and were negatively related to postural sway. However, the strength of these relationships was only moderate; continued analysis is exploring possible explanations for these results.

Abstract Introduction Sleep misperception is a phenomenon often identified in insomnia literature, in which individuals subjective reporting does not match objective measurements of their own sleep. Research indicates that anxiety symptoms may play a role in sleep misperception. This study assessed the relationship between sleep misperception, sleep quality, and anxiety in a young adult population with sub-clinical insomnia and anxiety symptoms. Linear regression models examined the relationships between sleep quality, anxiety symptoms, and sleep misperception. Methods This sample consisted of 130 young adults recruited from a University in the Bronx, NY. Anxiety was assessed using the Beck Anxiety Inventory (BAI), and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Objective measures of sleep were collected via wrist-based actigraphy over a period of 7-14 days. Subjective sleep measures were collected via an online sleep diary. A misperception index was calculated to determine the discrepancy between subjective and objective sleep measures based on a formula established in previous research. Results Higher anxiety symptoms were associated with greater sleep disturbance. Higher sleep misperception was not associated with greater sleep disturbance. There was a significant, positive relationship between sleep misperception and anxiety symptoms (r=0.18, p=0.000). Gender emerged as an important covariate, with males exhibiting significantly higher sleep misperception and underestimating TST (M=-0.31, SD=0.22) compared to females (M=-0.18, SD=0.12). Conclusion Sleep misperception was not related to sleep quality, but was strongly related to anxiety symptoms in this population. In a sub-clinical young adult sample, sleep misperception is associated with anxiety but not sleep quality, and has significant gender differences. These findings contribute to sleep misperception literature with potential applications in diagnosis and treatment of insomnia and anxiety. Support n/a

AbstractThe use of filters and editing tools for perfecting selfies is increasing. While some aesthetic experts have touted the ability of this technology to help patients convey their aesthetic goals, others have expressed concerns about the unrealistic expectations that may come from the ability for individuals to digitally alter their own photos in these so-called “super-selfies.” The aim of the study is to determine the changes that individuals seek when enhancing selfies. Twenty subjects participated in this study between July 25 and September 24, 2019. Subjects had two sets of headshots taken (neutral and smile) and were provided an introduction on the use of the Facetune2 app. Subjects received a digital copy of their photographs and were asked to download the free mobile app. After 1 week of trialing the different tools for enhancing their appearance, subjects submitted their self-determined most attractive edited photographs. Changes in marginal reflex distance (MRD) 1 and 2, nose height and width, eyebrow height, facial width, skin smoothness, skin hue, and saturation as well as overall image brightness were recorded. Paired two-tailed t-test was used to evaluate pre- and post-facial measurements. There were no statistically significant changes identified in the analysis of the altered photos in neutral expression. Analysis of all smiling photographs revealed that subjects increased their smile angle (right: +2.92 mm, p = 0.04; left: +3.58 mm, p < 0.001). When smiling photographs were assessed by gender, females were found to significantly increase their MRD2 (right: +0.64 mm, p = 0.04; left: +0.74 mm, p = 0.05) and their smile angle (right: +1.90 mm, p = 0.03; left: +2.31 mm, p = 0.005) while also decreasing their nose height (−2.8 mm, p = 0.04). Males did not significantly alter any of the facial measurements assessed. This study identifies the types of changes that individuals seek when enhancing selfies and specifies the different aspects of image adjustment that may be sought based on a patient's gender.
