Psychometric properties of the MOBITEC-GP mobile application for real-life mobility assessment in older adults

2022

Aim of this study was to test the reliability and validity of the life-space measures and walking speed delivered by the MOBITEC-GP app. Participants underwent several supervised walking speed assessments as well as a 1-week life-space assessment during two assessment sessions 9 days apart. Fifty-seven older adults (47.4% male, mean age= 75.3 (±5.9) years) were included in the study. The MOBITEC-GP app showed moderate to excellent test-retest reliability (ICCs between 0.584 and 0.920) and validity (ICCs between 0.468 and 0.950) of walking speed measurements of 50 meters and above and of most 1-week life-space parameters, including life-space area, time spent out-of-home, and action range.

Compartint visions sobre l’educació: Un projecte intergeneracional amb sèniors de la Universitat dels Majors y estudiants de Magisteri

2021

Memoria y patrimonio vivo es un proyecto de innovación educativa centrado en el diálogo intergeneracional de las experiencias de vida y de vida educativa entre estudiantes séniors (Universitat dels Majors) y juniors (estudiantes de Magisterio Infantil), que se ha desarrollado en la Universitat de València (Campus d’Ontinyent) con sesiones quincenales a lo largo de seis meses de trabajo. Durante el proyecto se estableció un diálogo intergeneracional sobre la educación a lo largo de la vida que permitió obtener diferentes visiones y superar estereotipos mutuos entre personas de distintas generaciones al aprender unas de otras a través de la interacción directa. El hecho de utilizar metodologí…

Longitudinal profiles of mental well-being as correlates of successful aging in middle age

2017

This study analyzed the multidimensional (including emotional, psychological, and social well-being) profiles of mental well-being and their links to various indicators of successful aging (SA; including diseases, cognitive and physical function, and engagement with life). The analyses were based on the Finnish Jyväskylä Longitudinal Study of Personality and Social Development, where the age-cohort participants have been followed from age 8 to 50. Data on 335 participants collected in mid-adulthood were analyzed. Applying Latent Profile Analysis and measures of life satisfaction and psychological well-being at ages 36, 42, and 50 and social well-being at ages 42 and 50, four longitudinal w…

Programas Educativos Universitarios Para Mayores: Evaluación de su Impacto en la Autopercepción del Apoyo Social y la Salud Mental

2015

Algunos estudios indican que los programas universitarios para mayores pueden tener un impacto positivo en la autopercepción del apoyo social y la salud de los participantes. Sin embargo, dichos estudios no evalúan estas variables con instrumentos de medida estandarizados y grupos de control dentro y fuera del programa. En el presente trabajo se utilizó un grupo experimental y dos grupos control que fueron evaluados en dos momentos con instrumentos estandarizados. Los resultados no confirmaron los efectos beneficiosos esperados de los programas. Es necesario seguir profundizando en esta línea de actuación y explorar el efecto de variables socioafectivas en estudios longitudinales. Some stud…

Age-Related Differences in Intermuscular Coherence EMG-EMG of Ankle Joint Antagonist Muscle Activity during Maximal Leaning

2022

Background: Intermuscular synchronization is one of the fundamental aspects of maintaining a stable posture and is of great importance in the aging process. This study aimed to assess muscle synchronization and postural stabilizer asymmetry during quiet standing and the limits of stability using wavelet analysis. Intermuscular synchrony and antagonistic sEMG-sEMG (surface electromyography) coherence asymmetry were evaluated in the tibialis anterior and soleus muscles. Methods: The study involved 20 elderly (aged 65 ± 3.6) and 20 young (aged 21 ± 1.3) subjects. The task was to perform a maximum forward bend in a standing position. The prone test was divided into three phases: quiet standing …

Relationship between cognitive performance and mobility over the life course

2018

We studied cross-sectional, longitudinal and temporal associations between executive function and life-space mobility in old age. We assessed the association between intellectual ability in early adulthood and physical functioning in old age, and the association between early life motor development and cognitive performance in early old age. The participants of the first dataset were 157 persons aged 76-91 y who were followed up for two years as part of the Life-Space Mobility in Old Age study, and who took part in measurements on executive function (EF) implemented with the Trail Making Test and Life-Space Assessment. The second dataset comprised persons from the Helsinki Birth Cohort Stud…

Exploring the conceptual framework and measurement model of intrinsic capacity defined by the World Health Organization: A scoping review

2022

WHO has defined intrinsic capacity (IC) as the composite of all physical and mental capacities of an individual covering five subdomains: cognition, locomotion, sensory, vitality, and psychological. Despite this well accepted definition, the conceptual and measurement model of IC remains unclear, which hampers a standardized operationalization of the construct. We performed a scoping review to give a comprehensive overview of the extent to which the current literature of IC addresses and assumes the conceptual framework and measurement model of IC as reflective or formative. For inclusion, we considered all types of articles that were published in peer-reviewed journals except for protocol …

Przedwczesne starzenie się organizmu – rola laminopatii

2021

Aging is a process, that went off inevitable and it is associated with the accumulation of macromolecular damage, genomic instability, and loss of heterochromatin. All these changes conduct to deterioration function of stem cells and reducing the ability to regenerate tissues. Current views on the structure and function of the cell nucleus in a normal or pathological cell are focused on the nuclear envelope, and especially on the lamins located in the inner nuclear membrane. The main component of the nuclear lamina is lamins belonging to intermediate filaments. Disorders of their functions, as a result of mutations, have serious health consequences, including leading to premature aging. It …

The assessment of the reliability of an innovative 3rd generation solar cell integrated with “thermal belt” glass block

2017

Glass block is a building product widely used for the construction of translucent building façades and roofs. The need to adapt the product to the regulations in the field of energy saving and environmental sustainability has led to the design of innovative configurations, through the integration of different sub-components. These ones are able to improve its energy performance by means of the integration of a“thermal belt”, cold glued to the glass shells, which constitute the traditional glass block, and 3rd generation solar cells. This paper reports the first results of the experimental program designed to assess some durability components: inherent and critical reliability. <div id="g…
