“…Via these sensors, the aTUG can automatically measure the total time of the TUG and of all sub-tasks of the instrumented TUG (iTUG), as proposed by Botolfson et al, (2008) [25]. Similarly, the recently proposed Short Physical Performance Battery (SPPB) kiosk [26] is intended for supervised assessments of the SPPB with its three components (namely gait speed, the 5SST, and standing balance) and intends to enhance inter-tester reliability in executing the SPPB protocol. With semi-automatic post-processing, SPPB kiosk's validity to estimate these SPPB-components was shown.…”

Comprehensive and repetitive assessments are needed to detect physical changes in an older population to prevent functional decline at the earliest possible stage and to initiate preventive interventions. Established instruments like the Timed “Up & Go” (TUG) Test and the Sit-to-Stand Test (SST) require a trained person (e.g., physiotherapist) to assess physical performance. More often, these tests are only applied to a selected group of persons already functionally impaired and not to those who are at potential risk of functional decline. The article introduces the Unsupervised Screening System (USS) for unsupervised self-assessments by older adults and evaluates its validity for the TUG and SST. The USS included ambient and wearable movement sensors to measure the user’s test performance. Sensor datasets of the USS’s light barriers and Inertial Measurement Units (IMU) were analyzed for 91 users aged 73 to 89 years compared to conventional stopwatch measurement. A significant correlation coefficient of 0.89 for the TUG test and of 0.73 for the SST were confirmed among USS’s light barriers. Correspondingly, for the inertial data-based measures, a high and significant correlation of 0.78 for the TUG test and of 0.87 for SST were also found. The USS was a validated and reliable tool to assess TUG and SST.

“…The maximum value was adjusted after all tests were conducted twice at 1-min intervals or longer. In addition, all subjects underwent the short physical performance battery (SPPB) using electronic SPPB toolkit (eSPPB) developed by Dyphi Inc. (Daejoen, Korea); it consisted of repeated chair stands, standing balance, and walking speed [ 20 ]. In the 5-time chair stand test, the time required by participants to complete 5 sit-to-stand maneuvers as quickly as possible was recorded.…”

The n-3 fatty acid (FA) has evoked considerable interest as a modifiable factor for maintenance of muscle health owing to its anti-inflammatory properties. To clarify this possibility, we investigated circulating n-3 FA level, a reliable biomarker of FA status in the body, in relation to sarcopenia in a cohort of Asian older adults. Blood samples were collected from 125 participants who underwent comprehensive assessment of muscle mass and function. Serum FA level was measured by gas chromatography/mass spectrometry. Sarcopenia was diagnosed using the cut-off points specified for the Asian population. After adjusting for sex, age, and body mass index, subjects with sarcopenia and those with low muscle strength had 36.5% and 32.4% lower serum n-3 levels (P = 0.040 and 0.030), respectively, than controls. The odds ratios per standard deviation increment in serum n-3 level for sarcopenia and low muscle strength were 0.29 and 0.40 (P = 0.015 and 0.028), respectively. A higher serum n-3 level was significantly associated with greater muscle strength (P = 0.038). These findings suggest a possible protective effect of n-3 FA on human muscle homeostasis. Further well-designed large-scale longitudinal studies are necessary to understand the definite role of circulating n-3 FA level in sarcopenia risk assessment.

Background Disability, which is considered a health-related condition, increases care demands and socioeconomic burdens for both families and communities. To confirm the trend of dynamic longitudinal changes in disability, this study aims to explore how disability is divided by the trajectory method, which deals with time-sequenced data. Additionally, this study examines the differences in demographics, geriatric conditions, and time spent at home among the trajectory groups in community-dwelling older adults. Home time is defined as the period during which the participant was not in a hospital or health care facility during their lifetime. Methods Records of 786 community-dwelling older participants were analyzed from the Aging Study of PyeongChang Rural Area, a population-based cohort study that took place over three years. Using 7 domains of activities of daily living and 10 domains of instrumental activities of daily living, participants were grouped into no dependency (0 disabled domain), mild (1 disabled domain), and severe (2 or more disabled domains) disability groups. The longitudinal trajectory group of disability was calculated as a trajectory method. Three distinct trajectory groups were calculated over time: a relatively-stable group (78.5 %; n=617), a gradually-aggravated group (16.0 %; n=126), and a rapidly-deteriorated group (5.5 %; n=43). Results The average age of 786 participants was 73.3 years (SD: 5.8), and the percentage of females was 52.7%. It was found that 78.5% of participants showed relatively no dependence and 5.5% of older adults in a rural area showed severe dependence. Through applying the trajectory method, it was shown that the Short Physical Performance Battery (SPPB) score was 10.2 points in the relatively-stable group and 3.1 points in the rapidly-deteriorating group by the 3 rd year. Additionally, by the trajectory method, the rate of decrease in home time was 3.33% in the rapidly-deteriorated group compared to the relatively-stable group. Conclusions This study shows the difference in demographics and geriatric conditions (such as SPPB) through the examination of longitudinal trajectory groups of disability in community-dwelling older adults. Significant differences were also found in the amount of home time among the trajectory groups.
