In response to the general inability of smart beds to meet the health needs of chronic disease management and long-term care, this study proposed to investigate smart bed comfort in different typical conditions. The objective body pressure distribution and subjective comfort of participants were collected when the smart bed was in typical conditions. Pressure sensor mat was used to accurately measure pressure distribution. Participants reported in real time on the subjective comfort for each typical condition. Statistical data analysis intended to investigate changes in overall and local comfort when the smart bed is in different typical conditions, the correlation between perceived comfort and body pressure distribution. During the experiment, mean and peak pressures increased by up to 87.19% and 92.85%, respectively, owing to changes in smart bed conditions. However, major body pressure indicators correlated with the overall and local comfort of each area were not completely aligned. Statistical data analysis shows the im-portance of evening out forces and reducing peak pressures. Apart from mean pressure, peak pressure, particularly at the buttock, thigh and shank areas, is the key factor in comfort evaluation. Moreover, adequate bed board partitioning and linkage mechanism between adjacent boards better fit the body curve and enhance comfort. Accordingly, ensuring relatively balanced body forces and avoiding the feeling of weightlessness improve user comfort and health significantly. The succeeding study will further investigate the relationship between smart bed comfort and changes in free lying positions and moving activities, hoping to provide a comfort studies basis for long-term care.

“…In this study, the interface pressure was calculated using two variables that indicated the strength and redistribution of pressure. The strength of pressure was identified using the peak pressure [ 26 , 27 ], and the redistribution of pressure was confirmed using the risk area ratio [ 28 ]. Using the XSENSOR X3 PX100 system (ForeSite SS Mattress System, XSENSOR Technology, Calgary, AB, Canada), we measured interface pressures in the subjects’ bony prominence sites.…”

Insufficient research exists for position change intervals to eradicate pressure ulcers. We tried to provide evidence for the position change interval by comparing peak pressure, risk area ratio, and the time to reach 30 mmHg and 60 mmHg, and presented this in detail, according to the angle in the three positions. The study conducted RCTs on a total of 64 healthy adults. For two hours, interface pressure measurements were compared with 30° and 90° tilting at the inclined, 0° and 45° head-of-bed (HOB) elevation at the supine, and 30° and 45° HOB elevation at the Fowler’s position. The peak pressure on 30° tilting remained less than 60 mmHg for 2 h, unlike 90° tilting. To reach 60 mmHg took 78.18 min at 30° tilting, within 30 min at the 30° supine, 30° and 45° at the Fowler’s position, and 39.55 min at 0° supine. The pressure difference according to the angles was only significant at 30° and 90° tilting, with no difference in the other groups. To prevent pressure ulcers, position changes are required every 2 h in the 30° tilting position, every 1.5 to 2 h at 0° supine, and at least every 1.5 h for all the other positions.

“…We operationally defined total lying time as the period within 24 hours each day spent in horizontal or near-horizontal position (e.g., Fowler position 24 ) , semi-Fowler position 25 ) , not involving high-Fowler position 26 ) ) in spite of the presence or absence of sleeping, napping, receiving massage, watching television, listening to radio, and so on, regardless of purpose or location. Firstly, participants were asked to recall retrospectively the average time per day they spent horizontally lying in the previous week in increments of 30 minutes as follows: “How many hours per day did you typically spend lying with or without doing something like sleeping, napping, receiving massage, watching television, listening to radio, or other on a usual day, regardless of purpose or place in the previous week?” The question to measure total lying time is referred to in previous studies as the single question to measure total sitting time 15 ) and the definition of sedentary behavior 2 , 27 ) .…”

[Purpose] To investigate reliability and discriminant validity of a single question about total lying time for assessing physical inactivity in community-dwelling older people. [Participants and Methods] The participants were 54 healthy older individuals (mean age, 72.5 years), who were asked to recall retrospectively their mean total lying and sleep times per day in the previous week (7 days). The total lying and sleep times per day in the forthcoming week (7 days) were also investigated prospectively after confirming the mean total lying and sleep times per day in the previous week, and their mean values per day were calculated. [Results] Intraclass reliability of total lying and sleep times per day in the forthcoming week were acceptable [ICC (1, 1) for total lying time=0.835, ICC (1, 1) for sleep time=0.707]. No significant difference in average total lying time between the previous (8.4 ± 2.0 hours/day) and forthcoming (8.7 ± 1.7 hours/day) weeks was seen. In the forthcoming week, average total lying time was significantly higher than average sleep time (7.1 ± 1.3 hours/day). There was low significant correlation between total lying time and sleep time. [Conclusion] Total lying time can be measured with acceptable reliability and discriminant validity, and is a different outcome than sleep time in community-dwelling older adults.
