BACKGROUND: Regaining walking ability is a key target in geriatric rehabilitation. This study evaluated the prevalence of walking ability at (pre-)admission and related clinical characteristics in a cohort of geriatric rehabilitation inpatients; in inpatients without walking ability, feasibility and effectiveness of progressive resistance exercise training (PRT) were assessed.METHODS: Inpatients within RESORT, an observational, longitudinal cohort of geriatric rehabilitation inpatients, were stratified in those with and without ability to walk independently (defined by Functional Ambulation Classification (FAC) score ≤ 2) at admission; further subdivision was performed by pre-admission walking ability. Clinical characteristics at admission, length of stay, and changes in physical and functional performance throughout admission were compared depending on (pre-)admission walking ability. Feasibility (relative number of PRT sessions given and dropout rate) and effectiveness [change in Short Physical Performance Battery, FAC, independence in (instrumental) activities of daily living (ADL/IADL)] of PRT (n = 11) in a subset of inpatients without ability to walk independently at admission (able to walk pre-admission) were investigated compared with usual care (n = 11) (LIFT-UP study).RESULTS: Out of 710 inpatients (median age 83.5 years; 58.0% female), 52.2% were not able to walk independently at admission, and 7.6% were not able to walk pre-admission. Inpatients who were not able to walk independently at admission, had a longer length of stay, higher prevalence of cognitive impairment and frailty and malnutrition risk scores, and a lower improvement in independence in (I)ADL compared with inpatients who were able to walk at both admission and pre-admission. In LIFT-UP, the relative median number of PRT sessions given compared with the protocol (twice per weekday) was 11 out of 44. There were no dropouts. PRT improved FAC (P = 0.028) and ADL (P = 0.034) compared with usual care.CONCLUSIONS: High prevalence of inpatients who are not able to walk independently and its negative impact on independence in (I)ADL during geriatric rehabilitation highlights the importance of tailored interventions such as PRT, which resulted in improvement in FAC and ADL.
Background: App-based mobile health exercise interventions can motivate individuals to engage in more physical activity (PA). According to the Fogg Behavior Model, it is important that the individual receive prompts at the right time to be successfully persuaded into PA. These are referred to as just-in-time (JIT) interventions. The Playful Active Urban Living (PAUL) app is among the first to include 2 types of JIT prompts: JIT adaptive reminder messages to initiate a run or walk and JIT strength exercise prompts during a walk or run (containing location-based instruction videos). This paper reports on the feasibility of the PAUL app and its JIT prompts.Objective: The main objective of this study was to examine user experience, app engagement, and users' perceptions and opinions regarding the PAUL app and its JIT prompts and to explore changes in the PA behavior, intrinsic motivation, and the perceived capability of the PA behavior of the participants.Methods: In total, 2 versions of the closed-beta version of the PAUL app were evaluated: a basic version (Basic PAUL) and a JIT adaptive version (Smart PAUL). Both apps send JIT exercise prompts, but the versions differ in that the Smart PAUL app sends JIT adaptive reminder messages to initiate running or walking behavior, whereas the Basic PAUL app sends reminder messages at randomized times. A total of 23 participants were randomized into 1 of the 2 intervention arms. PA behavior (accelerometer-measured), intrinsic motivation, and the perceived capability of PA behavior were measured before and after the intervention. After the intervention, participants were also asked to complete a questionnaire on user experience, and they were invited for an exit interview to assess user perceptions and opinions of the app in depth.Results: No differences in PA behavior were observed (Z=-1.433; P=.08), but intrinsic motivation for running and walking and for performing strength exercises significantly increased (Z=-3.342; P<.001 and Z=-1.821; P=.04, respectively). Furthermore, participants increased their perceived capability to perform strength exercises (Z=2.231; P=.01) but not to walk or run (Z=-1.221; P=.12). The interviews indicated that the participants were enthusiastic about the strength exercise prompts. These were perceived as personal, fun, and relevant to their health. The reminders were perceived as important initiators for PA, but participants from both app groups explained that the reminder messages were often not sent at times they could exercise. Although the participants were enthusiastic about the functionalities of the app, technical issues resulted in a low user experience.Conclusions: The preliminary findings suggest that the PAUL apps are promising and innovative interventions for promoting PA. Users perceived the strength exercise prompts as a valuable addition to exercise apps. However, to be a feasible intervention, the app must be more stable.
The six-minute walking test (6MWT) may be a practical test for the evaluation functional exercise capacity in children with end-stage renal disease (ESRD). The aim of this study was to investigate the 6MWT performance in children with ESRD compared to reference values obtained in healthy children and, secondly, to study the relationship between 6MWT performance with anthropometric variables, clinical parameters, aerobic capacity and muscle strength. Twenty patients (13 boys and seven girls; mean age 14.1 ± 3.4 years) on dialysis participated in this study. Anthropometrics were taken in a standardized manner. The 6MWT was performed in a 20-m-long track in a straight hallway. Aerobic fitness was measured using a cycle ergometer test to determine peak oxygen uptake (V⋅O2peak)(V⋅O2peak), peak rate (Wpeak) and ventilatory threshold (VT). Muscle strength was measured using hand-held myometry. Children with ESRD showed a reduced 6MWT performance (83% of predicted, p < 0.0001), irrespective of the reference values used. The strongest predictors of 6MWT performance were haematocrit and height. Regression models explained 59% (haematocrit and height) to 60% (haematocrit) of the variance in 6MWT performance. 6MWT performance was not associated with V⋅O2peakV⋅O2peak, strength, or other anthropometric variables, but it was significantly associated with haematocrit and height. Children with ESRD scored lower on the 6MWT than healthy children. Based on these results, the 6MWT may be a useful instrument for monitoring clinical status in children with ESRD, however it cannot substitute for other fitness tests, such as a progressive exercise test to measure V⋅O2peakV⋅O2peak or muscle strength tests.
Sociale isolatie wordt gerelateerd aan sterfterisico’s van roken, overgewicht en te hoge bloeddruk en zorgt voor een verhoogde kans op institutionalisering. Door de dubbele vergrijzing en maatschappelijke ontwikkelingen groeit de groep zelfstandig wonende senioren én de druk op de ouderenzorg in Nederland snel. Deze groep senioren heeft, naast een grote kans op één of meerdere chronische aandoeningen, grotere kans op eenzaamheid en sociale isolatie. De huidige coronapandemie vergroot deze sociale kwetsbaarheid. Echter, juist voor deze groep is een informeel netwerk en nabijheid van contacten cruciaal om langer zelfstandig thuis te kunnen wonen. Een lichte vorm van ‘gemeenschap’ en sociale interactie in de buurt is een voorwaarde voor het ontstaan van informele netwerken. Een semipublieke ruimte in de vorm van een dynamische ‘fourth place’, kan deze sociale interactie tussen buurtbewoners, waaronder kwetsbare ouderen, stimuleren en faciliteren. In ‘The Art of Connection’ fungeert de buitenruimte rond CPO Cohousing, gericht op meergeneratiewonen in de vergrijzende wijk Coehoorn te Arnhem, als ‘living lab’. Aansluitend bij de waarden van deze slimme, creatieve wijk, staat de volgende onderzoeksvraag staat centraal: Op welke manier kan een interactieve buitenruimte bijdragen aan het bevorderen van sociale interactie tussen bewoners, waaronder kwetsbare ouderen, in de wijk Coehoorn? In co-creatie met gebruikers en stakeholders wordt, in een iteratief proces, een prototype van een interactieve buitenruimte ontwikkeld. Deze wordt in een pilot geëvalueerd met behulp van big data, gecombineerd met observaties, interviews en expertmeetings. De beoogde resultaten leveren een bijdrage aan extramuralisering van kwetsbare ouderen door het bevorderen van sociale interactie tussen bewoners, en daarmee het versterken van een informele (zorg)netwerken. Door actieve betrokkenheid van buurtbewoners en andere (lokale) stakeholders, gedurende het hele proces, wordt een learning community gevormd, hetgeen de kans op een geslaagde interventie vergroot.
