Decrease in Mobility during the COVID-19 Pandemic and Its Association with Increase in Depression among Older Adults: A Longitudinal Remote Mobility Monitoring Using a Wearable Sensor

Sensors, Год журнала: 2021, Номер 21(9), С. 3090 - 3090

Опубликована: Апрель 29, 2021

Background: Social isolation during COVID-19 may negatively impact older adults’ wellbeing. To assess its impact, we measured changes in physical activity and sleep among community-dwelling adults, from pre-to post-pandemic declaration. Method: Physical adults (n = 10, age 77.3 ± 1.9 years, female 40%) were remotely assessed within 3-month 6-month declaration using a pendant-wearable system. Depression was pre-and the Center for Epidemiologic Studies scale compared with 48 h continuous monitoring data before pandemic. Results: Compared to pre-pandemic, time spent standing declined by 32.7% (Cohen’s d 0.78, p < 0.01), walking 52.2% (d 1.1, step-counts 55.1% 1.0, 0.016), postural transitions 44.6% 0.82, 0.017) increase sitting duration 20.5% 0.5, 0.049). symptoms increased 150% 0.8, 0.046). Interestingly, depression significantly correlated unbroken-prolong bout (ρ 0.677, 0.032), cadence −0.70, 0.024), −0.72, 0.019). Conclusion: This is one of early longitudinal studies highlighting adverse effect pandemic on objectively adults. Our observations showed need timely intervention mitigate hard reverse consequences decreased such as depression.

Systematic review on the application of wearable inertial sensors to quantify everyday life motor activity in people with mobility impairments

Journal of NeuroEngineering and Rehabilitation, Год журнала: 2020, Номер 17(1)

Опубликована: Ноя. 4, 2020

Abstract Background Recent advances in wearable sensor technologies enable objective and long-term monitoring of motor activities a patient’s habitual environment. People with mobility impairments require appropriate data processing algorithms that deal their altered movement patterns determine clinically meaningful outcome measures. Over the years, large variety have been published this review provides an overview measures, concepts algorithms, type placement required sensors as well investigated patient populations measurement properties. Methods A systematic search was conducted MEDLINE, EMBASE, SCOPUS October 2019. The strategy designed to identify studies (1) involved people impairments, (2) used inertial sensors, (3) provided description underlying algorithm, (4) quantified aspect everyday life activity. two authors independently screened hits for eligibility extraction narrative review. Results Ninety-five were included They covered measures which can be grouped into four categories: maintaining changing body position, walking moving, moving around using wheelchair, involve upper extremity. validity or reproducibility these outcomes fourteen different populations. Most evaluated algorithm’s accuracy detect certain unlabeled raw data. depends on activity measure are thoroughly described usability applied setups rarely reported. Conclusion This comprehensive applications quantify impairments. It summarizes state-of-the-art, it quick access relevant literature, enables identification gaps evaluation existing development new algorithms.

Wellbuilt for wellbeing: Controlling relative humidity in the workplace matters for our health

This study offers a new perspective on the role of relative humidity in strategies to improve health and wellbeing office workers. A lack studies sufficient participant size diversity relating (RH) measured outcomes has been driving factor relaxing thermal comfort standards for RH removing lower limit dry air. We examined association between objectively stress responses, physical activity (PA), sleep quality. diverse group workers (n = 134) from four well-functioning federal buildings wore chest-mounted heart rate variability monitors three consecutive days, while at same time, temperature (T) were their workplaces. Those who spent majority time conditions 30%-60% experienced 25% less than those drier conditions. Further, correlational our response suggests optimal values may exist within an even narrower range around 45%. Finally, we found indirect effect poorer quality, mediated by outside this range.

Abstract Background Globally the population of older adults is increasing. It estimated that by 2050 number over age 60 will represent 21% world’s population. Frailty a clinical condition associated with ageing resulting in an increase adverse outcomes. considered greatest challenge facing affecting 16% community-dwelling populations worldwide. Aim The aim this systematic review to explore how wearable sensors have been used assess frailty adults. Method Electronic databases Medline, Science Direct, Scopus, and CINAHL were systematically searched March 2020 November 2020. A search constraint articles published English, between January 2010 was applied. Papers included primary observational studies involving; aged > years, sensor provide quantitative measurements physical activity (PA) or mobility measure frailty.

Detecting Fall Risk and Frailty in Elders with Inertial Motion Sensors: A Survey of Significant Gait Parameters

Sensors, Год журнала: 2021, Номер 21(20), С. 6918 - 6918

Опубликована: Окт. 19, 2021

In the elderly, geriatric problems such as risk of fall or frailty are a challenge for society. Patients with present difficulties in walking and higher risk. The use sensors gait analysis allows detection objective parameters related to these pathologies make an early diagnosis. Inertial Measurement Units (IMUs) wearables that, due their accuracy, portability, low price, excellent option analyze human health-monitoring applications. Many relevant (e.g., step time, speed) used assess motor, even cognitive, health but we perceived that there is not full consensus on which most significant estimate state. this work, analyzed different IMU-based proposed literature state (robust, prefrail, frail) aim was collect parameters, measured from inertial sensors, able discriminate between patient groups highlight those controversy among examined works. For purpose, review studies published recent years carried out; apart 10 previous reviews using other sensing technologies, total 22 specific giving statistical significance values were analyzed. results showed double-support speed, stride number steps/day percentage/day, case detection, trunk stability movements relevant. Although important, works found limited them performed statistics subsets all possible parameters; fact highlights need new more complete set parameters.
