“…There seems to be a distinct difference between men and women. This difference has been clear in studies on FrC [16,49] as well as studies on balance and postural control [50,51]. In the current study we see that groups SEO2 and SEC2 consist mainly of women.…”

Human postural control is a complex system and changes as we age. Frequency based analyses have been argued to be useful to identify altered postural control strategies in balance tasks. The aim of this study was to explore the frequency domain of the quiet stance centre of pressure of older adults with various degrees of fall-related concerns and sensorimotor functioning. We included 45 community dwelling older adults and used a force plate to register 30 seconds of quiet stance with eyes open and closed respectively. We also measured sensory and motor functions, as well as fall-related concerns and morale. We analysed the centre of pressure power spectrum density and extracted the frequency of 4 of its features for each participant. Orthogonal projection of latent structures–discriminant analysis revealed two groups for each quiet stance trial. Group 1 of each trial showed less sensory and motor decline, low/no fall-related concerns and higher frequencies. Group 2 showed more decline, higher fall-related concerns and lower frequencies. During the closed eyes trial, group 1 and group 2 shifted their features to higher frequencies, but only group 1 did so in any significant way. Higher fall-related concerns, sensory and motor decline, and explorative balancing strategies are highly correlated. The control system of individuals experiencing this seems to be highly dependent on vision. Higher fall-related concerns, and sensory and motor decline are also correlated with the inability to adjust to faster, more reactive balancing strategies, when vision is not available.

“…A possible explanation to these findings would be the difference in sensitivity related to gender and aging. Papers assessing sensitivity in other situations demonstrated effects of gender and age 28,29 , which were more intense in women and in the younger people. The clarification of this hypothesis regarding dysphagia requires more specific studies.…”

Objective: to assess the difficulty in swallowing medications and correlate it with age and gender in healthy adults and elderly. Methods: a total of 439 asymptomatic healthy volunteers (270 females and 169 males), who were not taking any medication on a regular basis, aged from 20 to 84 years, were questioned as for dysphagia, by using the Eating Assessment Tool (EAT-10). Question number five of the EAT-10, specifically, approached the difficulty in swallowing drugs, considering zero as “no swallowing problem” and 1 to 4 as “some degree of difficulty” (4 as great difficulty).The chi-square test (x2) was used for the statistical analysis. Results: a total of 365 (83%) volunteers reported having no difficulty in swallowing medications (89% of men and 80% of women), whereas 74 (17%) reported some degree of difficulty (11% of men and 20% of women)(p = 0.01). These represented 20% of those aged between 20 and 49, and 9% of those aged 50 and over (p = 0.02). Conclusion: in this study, it was observed that both age and gender influence on medication swallowing, a difficulty more frequent among women and young adults. Some degree of difficulty was reported by 17% of the volunteers.

“…The findings also revealed no significant sex-related effect on one- and two-legged postural balance performance. Several studies have found that older men exhibit impaired balance performance (i.e., higher CoP sway movement) more than women (Era et al, 1997 ; Masui et al, 2005 ; Puszczalowska-Lizis et al, 2018 ), whereas other studies reported that older women have increased postural sway compared with men (Kim et al, 2010 ; Riva et al, 2013 ; Chen et al, 2019 ). It has also been reported that the smaller body height of women is an important explanatory factor for increased balance performance (Era et al, 1996 ; Bryant et al, 2005 ), with the difference between the sexes being largely removed when CoP trajectory was normalized to body height (Bryant et al, 2005 ).…”

“…Furthermore, CoP amplitude-based parameters are typically used as primary outcome measures and have been found to relate with age-related differences in balance performance (Prieto et al, 1996 ). These measures of static postural control are also typically employed in detecting sex-related differences, with some studies reporting greater CoP sway movement in older women (Kim et al, 2010 ; Riva et al, 2013 ; Chen et al, 2019 ), while others found older men to have increased postural sway compared with women (Era et al, 1997 ; Masui et al, 2005 ; Puszczalowska-Lizis et al, 2018 ).…”

Dance has been suggested to be an advantageous exercise modality for improving postural balance performance and reducing the risk of falls in the older population. The main purpose of this study was to investigate whether visual restriction impacts older dancers and non-dancers differently during a quiet stance balance performance test. We hypothesized higher balance performance and greater balance deterioration due to visual restriction in dancers compared with non-dancers, indicating the superior contribution of the visual channel in the expected higher balance performances of dancers. Sixty-nine (38 men, 31 women, 74 ± 6 years) healthy older adults participated and were grouped into a Greek traditional dance group (n = 31, two to three times/week for 1.5 h/session, minimum of 3 years) and a non-dancer control group (n = 38, no systematic exercise history). The participants completed an assessment of one-legged quiet stance trials using both left and right legs and with eyes open while standing barefoot on a force plate (Wii, A/D converter, 1,000 Hz; Biovision) and two-legged trials with both eyes open and closed. The possible differences in the anthropometric and one-legged balance parameters were examined by a univariate ANOVA with group and sex as fixed factors. This ANOVA was performed using the same fixed factors and vision as the repeated measures factor for the two-legged balance parameters. In the one-legged task, the dance group showed significantly lower values in anteroposterior and mediolateral sway amplitudes (p = 0.001 and p = 0.035) and path length measured in both directions (p = 0.001) compared with the non-dancers. In the two-legged stance, we found a significant vision effect on path length (p < 0.001) and anteroposterior amplitude (p < 0.001), whereas mediolateral amplitude did not differ significantly (p = 0.439) between closed and open eyes. The dance group had a significantly lower CoP path length (p = 0.006) and anteroposterior (p = 0.001) and mediolateral sway amplitudes (p = 0.003) both in the eyes-open and eyes-closed trials compared with the control group. The superior balance performance in the two postural tasks found in the dancers is possibly the result of the coordinated, aesthetically oriented intersegmental movements, including alternations between one- and two-legged stance phases, that comes with dance. Visual restriction resulted in a similar deterioration of balance performance in both groups, thus suggesting that the contribution of the visual channel alone cannot explain the superior balance performance of dancers.
