Validity and reproducibility of the Physical Activity Scale for the Elderly (PASE) questionnaire for the measurement of the physical activity level i…
2014
Background The need for valid and reproducible questionnaires to routinely assess the physical activity level of patients after total knee arthroplasty (TKA) is of particular concern in clinical settings. Aims of this study were to evaluate the validity and reproducibility of the physical activity scale for the elderly (PASE) questionnaire in TKA patients, with a particular view on gender differences. Methods A total of 50 elderly patients (25 women and 25 men aged 70 ± 6 years) following primary unilateral TKA were recruited. The reproducibility was evaluated by administering the PASE questionnaire during two occasions separated by 7 days. The construct (criterion) validity was investigate…
Color-coded diffusion-tensor-imaging of posterior cingulate fiber tracts in mild cognitive impairment.
2005
Abstract Different processes like microvascular dysfunction, free radical toxicity, β-amyloid deposits, and Wallerian degeneration can cause functionally relevant disturbances of cerebral neuronal networks by myelin degeneration. Color-coded diffusion-tensor-imaging (ccDTI) allows the structural identification and quantification of myelinated fiber tracts. Particularly, posterior cingulate fiber tracts, which are regarded as important neuronal substrates of the network representing memory processing can be localized only imprecisely by conventional magnetic resonance imaging techniques. The posterior cingulate bundles were assessed by ccDTI in 17 patients with amnestic mild cognitive impair…
How does early developmental assessment predict academic and attentional-behavioural skills at group and individual levels?
2009
The main aim of the study was to explore the ability of a brief developmental assessment to predict teacher-rated learning and attentional and behavioural skills in the first grade of school at both the group and individual levels. A sample of 394 children (181 males, 213 females) aged 4 years were followed to the age of 6 years, and 283 of the children (145 males, 138 females; mean age 7 y 11 mo) were followed further to the first grade (age 7 y) at school. The children were administered a brief but comprehensive developmental assessment (Lene - a neurodevelopmental screening method) at their local child health-care centres at ages 4 and 6 years. In the first grade, teachers completed a de…
Motor speed and lower extremity strength as predictors of fall-related bone fractures in elderly individuals.
2006
Background and aims: The purpose of this prospective population-based study was to examine the combined effects of motor speed and knee extension strength on risk of fall-related bone fractures in elderly individuals over a 10-year period. Methods: Participants were 307 men and women aged 75 or 80 years at baseline, who visited the research laboratory at the University of Jyvaskyla, Finland. Multi-choice motor speed tests and maximal isometric knee extension strength tests were carried out at baseline. Information on fractures was collected from hospital and health center records. The presence of impairment was defined as a score in the lowest tertile of sex- and age-stratified distribution…
Muscle strength and mobility as predictors of survival in 75-84-year-old people.
1995
The purpose of the study was to examine the association of physical capacity, as determined on the basis of self-report and physical measurements, with survival in three groups of elderly people aged 75, 80 and 75-84 years. The main aspects of physical capacity were mobility, walking speed, hand grip strength and knee extension strength. Although 1142 persons participated in mobility interview, of whom 466 also took part in the walking speed test, and 463 in the strength tests. The follow-up periods ranged from 48 to 58 months. Risk of death was significantly related to difficulties in indoor mobility among the 75-84-year-olds (odds ratio = 1.99, 95% confidence interval = 1.27-3.13) and 75-…
Using the Multidimensional Prognostic Index to Predict Clinical Outcomes of Hospitalized Older Persons: A Prospective, Multicenter, International Stu…
2018
Abstract Background Multidimensional Prognostic Index (MPI) is useful as a prognostic tool in hospitalized older patients, but our knowledge is derived from retrospective studies. We therefore aimed to evaluate in a multicenter, longitudinal, cohort study whether the MPI at hospital admission is useful to identify groups with different mortality risk and whether MPI at discharge may predict institutionalization, rehospitalization, and use of home care services during 12 months. Methods This longitudinal study, carried out between February 2015 and August 2017, included nine public hospitals in Europe and Australia. A standardized comprehensive geriatric assessment including information on f…
Absent pedal pulse and impaired balance in older people: a cross-sectional and longitudinal study
2006
Background and aims: The purpose of this study was to determine the relationship between abnormal pedal pulse status and postural balance in older people. Methods: Prospective, population-based cohort study of older residents in the city of Jyvaskyla, Finland. A total of 419 individuals aged 75 or 80 at baseline, with known lower extremity pulse status and balance tests performed on a force platform, were eligible for analysis. Results: Cross-sectionally, persons with both dorsal pedal artery pulses absent were found to sway more (p=0.047 anteroposterior velocity, normal standing eyes-open position). The risk of being unable to do the full tandem stance was twofold (OR=2.20, 95% CI 1.29–3.7…

Depressive symptoms in late life: a 10-year follow-up
2003
The objectives of this study were to describe the changes occurring in depressive symptomatology over a 10-year period among 75-year-old residents of Jyväskylä, Finland. It also addressed the question of whether the mood disturbances detected were a permanent phenomenon or whether they had a more episodic nature. In addition, various associations with and predictors of low mood were studied. Depressive symptoms were screened with the Center for Epidemiologic Studies Depression Scale (CES-D).The cut-off point of 16 was used to distinguish depressed individuals from those classified as non-depressed. A baseline study was carried out in 1989 (n = 337). A 5-year follow-up was carried out with t…
Changes in blood pressure in a large cohort of elderly individuals: Study 3C
2009
Summary Objective Analysis of changes in blood pressure with a two-year interval, and of factors associated with this change, in a large cohort of elderly individuals. Methods Follow-up of a cohort of 9294 individuals aged 65 years and over recruited from the general population for Study 3C. Changes in blood pressure are defined as the difference in its averages between the inclusion visit and the follow-up visit at 2 years. The factors associated with changes in systolic blood pressure were identified by univariate and multivariate analyses. Results Systolic and diastolic blood pressure decreased on average by 7.60 mmHg and 4.45 mmHg respectively in 7659 individuals included in the study b…
