“…In addition, swallowing reflex elicitation, like salivary swallowing, could occur unconsciously, but chewing can only be performed in an awake state [39]. Previous studies have shown that older adults with low ADL who stay away from bed for more than 6 h a day have stable arousal, and it is known that cerebral activity increases when in sitting or upright positions [40][41][42]. Therefore, it can be inferred that spending away from bed for more than 6 h and promoting arousal affected swallowing function.…”

Introduction: The aim of this study was to determine the associations of time spent away from bed with whole-body muscle mass and swallowing function in older adults with low activities of daily living (ADL). Methods: This cross-sectional study was conducted at Tokyo Medical and Dental University and included adults over 65 years of age who underwent a medical intervention at their residence. Data regarding age, sex, body height and weight, activity status, medical history, time spent away from bed, and Functional Oral Intake Scale (FOIS) were collected. We calculated the body mass index, Charlson Comorbidity Index, whole-body muscle mass, the appendicular skeletal muscle mass index (ASMI), and the trunk muscle mass index (TMI). According to the time spent away from bed, the subjects were grouped as follows: <4 but ≥0 h (S), <6 but ≥4 h (M), and ≥6 h (L). These variables were analyzed using the one-way analysis of variance, the Kruskal-Wallis test, and the χ2 test, then differences among the three groups were examined. To adjust for confounding factors, we performed multiple regression analysis with ASMI and TMI as the dependent variables and ordinal logistic regression analysis with FOIS as the objective variable. Results: Ninety subjects (male: n = 42; female: n = 48; mean age = 82.9 ± 8.8 years, and groups S: n = 23; M: n = 30; L: n = 37) were analyzed. Group L had a significantly higher ASMI, TMI, and FOIS score than groups S and M, while group M had a significantly higher ASMI and FOIS score than group S. After adjusting for confounding factors, the significant explanatory factors for ASMI were sex, activity status, time spent away from bed, and TMI. The factors for TMI were activity status, time spent away from bed, ASMI, and FOIS. The factors for FOIS were time spent away from bed and TMI. Conclusion: Spending 4 or more hours away from the bed is related to appendicular skeletal muscle mass and FOIS, while spending 6 or more hours is related to appendicular skeletal muscle mass, trunk muscle mass, and FOIS in this population. These findings highlight factors that can prevent a decline in swallowing function in the daily life of older adults with low ADL who have difficulty performing exercises to preserve swallowing function.

We aimed to investigate seated-posture body pressure distribution at the back-and buttock-supporting interfaces of the newly designed chair based on geriatric seated-posture. MethodsThe subjects were 33 women elderly care home residents aged ≥75 years. Subjects sat in the designed chair or a conventional chair for 30 min, and their body pressure distribution was recorded at 1, 10, 20 and 30 min after sitting down. Interface areas, mean and peak pressures were determined for each time point from the recorded data and two-way analysis of variance with repeated measurements was performed. ResultsFor the back-supporting interface, we found significant main effect in the type of chair. The designed chair had a wider back-supporting interface area than the conventional chair. At the mean and peak pressures, both back-and buttock-supporting interfaces showed a significant main effect depending on the type of the chair. In addition, at the mean pressures, buttock-supporting interfaces showed a significant main effect depending on the time point from the recorded data. In each case, the pressures were lower in the designed chair than in the conventional chair. We found a significant interaction in buttock-supporting mean pressures based on the type of chair and the time point from the recorded data. DiscussionResults suggest that the body pressures of the designed chair could be lower than those of conventional chair as the body pressures were dispersed over the interface area to contact the back-and buttock-supporting interfaces by the seated posture of the designed chair.
