Foot loading in normal and pathological walking

2002

Perusteellinen kävely- ja kuormitusanalyysi on usein tarpeellinen jalkaongelmissa, jotta mahdollinen tukien ja ortoosien valinta sekä alaraajoihin kohdistuvien leikkausten jälkeinen kuntoutus pystytään suorittamaan parhaalla mahdollisella tavalla, toteaa Jarmo Perttunen väitöstutkimuksessaan. Kävelijä tuottaa tukivaiheen aikana alustaan voimia pysty- ja vaakasuunnassa, joita on perinteisesti mitattu voimalevyantureilla. Ne eivät pysty yksistään erottelemaan kuormitusta jalkapohjan eri osien välillä riittävän täsmällisesti. Kiinnostus selvittää kuormitus tarkasti on johtanut kehityksen alkeellisista jalkapohjan mustekuvista hyvin pieniin kengän sisälle asetettaviin mittausantureihin. Perttus…

Effects of Physical and Cognitive Training on Gait Speed and Cognition in Older Adults : A Randomized Controlled Trial

2021

Gait speed is a measure of health and functioning. Physical and cognitive determinants of gait are amenable to interventions, but best practices remain unclear. We investigated the effects of a 12‐month physical and cognitive training (PTCT) on gait speed, dual‐task cost in gait speed, and executive functions (EFs) compared to physical training (PT) (ISRCTN52388040). Community‐dwelling older adults, who did not meet physical activity recommendations, were recruited (n=314). PT included supervised walking/balance (once weekly) and resistance/balance training (once weekly), home exercises (2‐3 times weekly) and moderate aerobic activity 150 minutes/week in bouts of >10 minutes. PTCT included …

Muscle-tendon mechanics and energetics during walking, running and jumping.

2012

In the human lower limb, muscles and tendon tend to interact in an efficient manner during common movements like walking, running and jumping. This pattern of interaction exploits the ability of muscles to produce forces efficiently at low shortening velocities, whilst tendons act as springs that help to store elastic energy during the contact phase, and return a large proportion of the energy in the pushoff phase. This pattern of muscletendon interaction can be disrupted in novel tasks or as a consequence of ageing or disease, resulting in a decrease in movement efficiency. peerReviewed

Associations of Environmental Features With Outdoor Physical Activity on Weekdays and Weekend Days: A Cross-Sectional Study Among Older People

2020

Background: Physical activity (PA) of higher intensity and longer duration mainly accumulates from older adults' out-of-home activities. Outdoor PA is influenced by environmental features; however, the day-to-day variability of PA and its associations with environmental features have not been widely studied. This study focused on the associations of environmental features with accelerometer-measured PA in older people on weekdays and weekend days.Methods: The study population comprised 167 community-dwelling older people aged 75–90 years. Accelerometers were worn on 7 consecutive days and a structured interview on physical functioning, health, and socioeconomic factors was administered. A g…

Clustering of reported activity destinations and use of active transport among older adults

2022

Background Conducting everyday activities out-of-home may accumulate a large share of older adults' daily physical, especially if active transportation is used. Environmental features in home neighborhood may motivate for higher physical activity, but the role of features around destinations is less known. Our goal was to study 1) clustering of older adults' reported activity destinations, and 2) whether transport mode to a destination was associated with characteristics of destination clusters. Methods Data comprise AGNES study participants (901 community-dwelling people aged 75-85 years living in city of Jyväskylä, Finland; 57% women) combined with geospatial data. Using digital mapping, …

Biopolymer Recovery from Aerobic Granular Sludge and Conventional Flocculent Sludge in Treating Industrial Wastewater: Preliminary Analysis of Differ…

2022

The recovery of biopolymers from sewage sludge could be a crucial step in implementing circular economy principles in wastewater treatment plants (WWTP). In this frame, the present study was aimed at evaluating the simultaneous production of polyhydroxyalkanoates (PHA) and extracellular polymeric substances (EPS) obtainable from the treatment of agro-industrial wastewater. Two biological enrichment systems, aerobic granular sludge (AGS) and a conventional activated sludge operating as a sequencing batch reactor (SBR), were monitored for 204 and 186 days, respectively. The maximum biopolymers accumulation capacity was close to 0.60 mgPHA-EPS gVSS−1 in the AGS when operating at 3 kgCODm…

Alcohol use, aquatic injury, and unintentional drowning : A systematic literature review

2018

Issues Drowning is a global public health issue, and there is a strong association between alcohol and risk of drowning. No previous systematic review known to date has identified factors associated with alcohol use and engagement in aquatic activities resulting in injury or drowning (fatal and non‐fatal). Approach Literature published from inception until 31 January 2017 was reviewed. Included articles were divided into three categories: (i) prevalence and/or risk factors for alcohol‐related fatal and non‐fatal drowning and aquatic injury, (ii) understanding alcohol use and aquatic activities, and (iii) prevention strategies. Methodological quality of studies was assessed using National He…

Extended Families as Communities of Religious Experience in Late Seventeenth-Century Eastern Finland

2022

AbstractThis chapter offers an interpretation of extended families as communities of experience in a rural area close to the eastern border of the Swedish realm. Through a case study of lower court records, Kuha examines the social and religious life in a 17th-century farm culminating in the crisis of an extended family. The chapter explores how practices of lived religion shaped the relationship of the community and the individual, and how experiences were negotiated within families and local communities. The analysis highlights the importance of protecting the boundaries of the household as well as the meaning of religious practices in creating cohesion within the community.

Contre la fausse objectivité, le perspectivisme assumé ? le reportage « gonzo » de Goldin, Clark, D’Agata, Tillmans contre la photographie « document…

2019

International audience; Après 1945, un certain nombre de praticiens de la « photographie plasticienne »privilégièrent le reportage « communautaire » : une plongée, sur le long terme, au sein d’ungroupe d’individus, souvent connus, voire intimes, du photographe, qui loin de se placercomme un témoin neutre, activait le mécanisme de l’observation participante chère àl’ethnographie. Larry Clark en fournit un exemple avec la série Tulsa (1971), la premièred’une longue lignée. Nan Goldin amplifia d’autant l’inclusion de l’autrice par la pratique del’autoportrait en situation dans The Ballad of Sexual Dependency (1981-1996). Plus tard desartistes comme Antoine d’Agata ou Wolfgang Tillmans poursuiv…
