Despite increasing use in the literature of old age,'frailty' remains an ill-defined term. The components offrailty have not been sufficiently defined to be used toidentify a research population or a group requiring apublic health intervention. It is currently too indefinitea state to be used to identify particular needs in anindividual, indeed being 'too frail' may be used tojustify investigative and therapeutic nihilism. However,we contend that, properly defined, with the majorcontributing… 
Conceptualisation and Measurement of Frailty in Elderly People
TLDR
The relationship between frailty, aging and disability is discussed and the essential feature of frailty is the notion of risk due to instability, which has been only poorly measured to date.
Frailty in elderly people
TLDR
Developing more efficient methods to detect frailty and measure its severity in routine clinical practice would greatly inform the appropriate selection of elderly people for invasive procedures or drug treatments and would be the basis for a shift in the care of frail elderly people towards more appropriate goal-directed care.
Frailty in Older Adults: An Evolutionary Concept Analysis
  • C. Tocchi
  • Medicine
    Research and Theory for Nursing Practice
  • 2015
TLDR
The results from this analysis conclude frailty in older adults is a tenuous state of health that is the result of the complex interplay of physiological, psychosocial, and environmental stressors that increases an older adult’s susceptibility to adverse health outcomes.
What is the frailty in elderly? Value and significance of the multidimensional assessments.
TLDR
A critical revision of the concept of frailty in elderly going back to its first indication (1978), where the method of multidimensional evaluation (MDE) is the first choice for the early diagnosis of "elderly frailty" (EF).
Tools for Assessing Frailty in Older People: General Concepts.
TLDR
This work advocates the choice of an appropriate measurement tool be based on the population characteristics and the purpose for which it is to be used and illustrates how an understanding of the properties of different tools helps to inform this choice.
Frailty in Older People Summary
  • 2014
Frailty is the most problematic expression of population ageing. It is a state of vulnerability to poor resolution of homeostasis following a stress and is a consequence of cumulative decline in
Frailty, Sarcopenia, Falls and Fractures
Frailty is a multidimensional phenomenon of increased vulnerability to the challenge of an acute illness, injury or social crisis. It overlaps with but is distinct from multi-morbidity and
Frailty: Defining and measuring of a concept
TLDR
Successful interventions against frailty include increasing muscle strength through training and individualized recommendations made on the basis of an extensive geriatric assessment.
Frailty Intervention Trial (FIT)
TLDR
This project will assess whether an intervention specifically targeting frailty can be implemented, and whether it is effective when compared to usual care, and will establish a new approach to the treatment of older people at risk of further functional decline and institutionalisation.
Thema kwetsbaarheid
TLDR
Although the prevalence of frailty is not expected to rise until 2020, the absolute number of frail older persons increases with a factor 1.5, and it seems therefore important to make efforts to prevent or postpone frailty as much as possible.

Who are the frail elderly?
TLDR
A definition is proposed which, it is believed, describes these extremes of biological and chronological age which, in the parlance of contemporary gerontology, are 'fit' and 'frail'.
Frailty in elderly people: an evolving concept.
TLDR
Existing definitions of frailty are reviewed and an alternative working definition is examined to discover if this understanding offers any useful insights.
Exercise physiology in geriatric practice.
  • A. Young
  • Medicine
    Acta medica Scandinavica. Supplementum
  • 1986
TLDR
There is an urgent need for close collaboration between exercise physiologists and geriatric clinicians, and the relationship between disability in activities of daily living and age-related impairment of physical performance is especially ripe for study.
The physics of frailty.
  • W. Bortz
  • Medicine, Physics
    Journal of the American Geriatrics Society
  • 1993
TLDR
Frailty results where the organism is uncoupled from its environment yielding a break in the forward feedback cycle of stimulus to reaction to growth to increased functional competence to improved response to stimulus.
Preventing frail health.
TLDR
There is sufficient epidemiologic and experimental evidence to conclude that frailty is also due to the additive effects of low-grade physiologic loss resulting from a sedentary lifestyle and more rapid loss due to acute insults that result in periods of limited activity and bedrest.
Shared risk factors for falls, incontinence, and functional dependence. Unifying the approach to geriatric syndromes.
TLDR
It may be possible to restore compensatory ability and prevent or delay the onset of several geriatric syndromes and, perhaps, functional dependence by modifying a shared set of predisposing factors.
A multifactorial intervention to reduce the risk of falling among elderly people living in the community.
TLDR
The multiple-risk-factor intervention strategy resulted in a significant reduction in the risk of falling among elderly persons in the community and among persons who had the targeted risk factors for falling, as compared with the control group.
Disability and cognitive impairment are risk factors for pneumonia-related mortality in older adults.
TLDR
Inability to walk a half mile, climb stairs, or perform heavy housework was significantly associated with increased risk of pneumonia mortality for women but not for men in the same multivariate models, and men and women whose body-mass index was above the median had significantly lower risk of tuberculosis mortality compared with those in the lowest quartile.
Cognitive impairment and mortality in a cohort of elderly people
TLDR
The relation between cognitive function and risk of death from stroke suggests that cerebrovascular disease is an important cause of declining cognitive function, and vitamin C status may be a determinant of cognitive function in elderly people through its effect on atherogenesis.
Physical performance measures in aging research.
TLDR
It is suggested that more widespread use be made of physical performance assessments and that they be evaluated as measures of functioning in cross-national studies, as indicators of change in functioning over time, as endpoints in intervention studies, and as tools for identifying persons functioning at high levels.
