Background in 2010, the European Working Group on Sarcopenia in Older People (EWGSOP) published a sarcopenia definition that aimed to foster advances in identifying and caring for people with sarcopenia. In early 2018, the Working Group met again (EWGSOP2) to update the original definition in order to reflect scientific and clinical evidence that has built over the last decade. This paper presents our updated findings. Objectives to increase consistency of research design, clinical diagnoses and ultimately, care for people with sarcopenia. Recommendations sarcopenia is a muscle disease (muscle failure) rooted in adverse muscle changes that accrue across a lifetime; sarcopenia is common among adults of older age but can also occur earlier in life. In this updated consensus paper on sarcopenia, EWGSOP2: (1) focuses on low muscle strength as a key characteristic of sarcopenia, uses detection of low muscle quantity and quality to confirm the sarcopenia diagnosis, and identifies poor physical performance as indicative of severe sarcopenia; (2) updates the clinical algorithm that can be used for sarcopenia case-finding, diagnosis and confirmation, and severity determination and (3) provides clear cut-off points for measurements of variables that identify and characterise sarcopenia. Conclusions EWGSOP2's updated recommendations aim to increase awareness of sarcopenia and its risk. With these new recommendations, EWGSOP2 calls for healthcare professionals who treat patients at risk for sarcopenia to take actions that will promote early detection and treatment. We also encourage more research in the field of sarcopenia in order to prevent or delay adverse health outcomes that incur a heavy burden for patients and healthcare systems.

Statistical Methods for Health Care Research

OBJECTIVE: to examine the clinical evidence reporting the prevalence of sarcopenia and the effect of nutrition and exercise interventions from studies using the consensus definition of sarcopenia proposed by the European Working Group on Sarcopenia in Older People (EWGSOP).METHODS: PubMed and Dialog databases were searched (January 2000-October 2013) using pre-defined search terms. Prevalence studies and intervention studies investigating muscle mass plus strength or function outcome measures using the EWGSOP definition of sarcopenia, in well-defined populations of adults aged ≥50 years were selected.RESULTS: prevalence of sarcopenia was, with regional and age-related variations, 1-29% in community-dwelling populations, 14-33% in long-term care populations and 10% in the only acute hospital-care population examined. Moderate quality evidence suggests that exercise interventions improve muscle strength and physical performance. The results of nutrition interventions are equivocal due to the low number of studies and heterogeneous study design. Essential amino acid (EAA) supplements, including ∼2.5 g of leucine, and β-hydroxy β-methylbutyric acid (HMB) supplements, show some effects in improving muscle mass and function parameters. Protein supplements have not shown consistent benefits on muscle mass and function.CONCLUSION: prevalence of sarcopenia is substantial in most geriatric settings. Well-designed, standardised studies evaluating exercise or nutrition interventions are needed before treatment guidelines can be developed. Physicians should screen for sarcopenia in both community and geriatric settings, with diagnosis based on muscle mass and function. Supervised resistance exercise is recommended for individuals with sarcopenia. EAA (with leucine) and HMB may improve muscle outcomes.

What is the evidence for physical therapy poststroke? A systematic review and meta-analysis.

Background: Identification of older persons at risk for the loss of independence, onset of (co)-morbidity or functional limitations through screening/assessment is of interest for the public health-care system. To date several different measurement instruments for overall physical function are frequently used in practice, but little information about their psychometric properties is available. Objectives and Methods: Our aim was to assess instruments with an overall score related to functional status and/or physical performance on content and psychometric properties. Electronic databases (Medline, EMBASE, AMED, Cochrane Library and CINAHL) were searched, using MeSH terms and relevant keywords. Studies, published in English, were included if their primary or secondary purpose was to evaluate the measurement properties of measurement instruments for overall physical function in community-dwelling older persons aged 60 years and older. Reliability, validity, responsiveness and practicability were evaluated, adhering to a specified protocol. Results: In total 78 articles describing 12 different functional assessment instruments were included and data extracted. Seven instruments, including their modified versions, were evaluated for reliability. Nine instruments, including their modified versions, were evaluated with regard to validity. Conclusion: In conclusion, the Short Physical Performance Battery can be recommended most highly in terms of validity, reliability and responsiveness, followed by the Physical Performance Test and Continuous Scale Physical Functional Performance.

The Importance of Physical Activity Exercise among Older People.

Objective: the positive effect of physical training in healthy elderly people is well documented. The aim of this systematic review was to describe the effect of physical training on physical performance in institutionalised elderly patients with multiple diagnoses. Design: systematic literature review of randomised controlled trials regarding effects of physical training of elderly (70+) subjects. Methods: the randomised controlled trials were evaluated using a modiWed version of an evaluation form originally developed by the Cochrane Collaboration. It is based on a weighted scale of 0–100 points, and ranks the studies as high, moderate or low methodological quality. A total of 16 randomised controlled trials were included in the review. Results: six studies scored as high quality, eight as moderate and two as low. There was a large heterogeneity in the studies concerning sample size, types of interventions and types of assessments. There is strong evidence for a positive effect of physical training on muscle strength and mobility; moderate evidence for an effect on range of motion; and contradictory evidence regarding gait, activities of daily living, balance and endurance. Conclusions: more studies are required, with larger sample sizes, higher speciWcity as to the types of interventions and assessments, greater focus on clinically relevant outcomes such as endurance and activities of daily living, and also, for example, quality of life and mortality.

Effects of physical training on physical performance in institutionalised elderly patients (70+) with multiple diagnoses

The number of available walking tests has increased dramatically over the past decades. Therefore, it is highly important to help clinicians choose the most appropriate walking test for a specific setting. This systematic review aimed to critically evaluate the reliability, validity, and responsiveness of clinical walking speed in a broad population of elderly persons living in the community, sheltered housing, or institutions. Literature searches were performed in several different databases. Key words were based on the topic of the measurement properties of performance-based clinical tools for quantifying walking. The instrument selected for review was walking speed. The methods and results of all the evaluated measurement properties were rated by using a standard checklist for appraising the qualitative attributes and measurement properties of the instrument. A total number of 3,781 abstracts were reviewed, and 86 articles were chosen for inclusion. Habitual walking speed seems to be highly reliable in community-dwelling people and residents in mixed settings. There have not been any studies that accord with our inclusion and exclusion criteria that have evaluated the reliability of maximum walking speed in an aged population. Walking speed is a highly valid test, both at habitual and maximum speed. Few studies gave information about responsiveness for walking speed, which means that these results cannot be evaluated properly. Habitual walking speed is a reliable measure, but maximum walking speed needs further evaluation. Both habitual and maximum walking speeds are valid instruments, and they predict death, hospitalization/institutionalization, and decline in mobility.

Investigation into the reliability and validity of the measurement of elderly people's clinical walking speed: A systematic review

Background and aims: There are few studies published that combine the interventions of physical training and nutrition. The aim of the present study was to describe the impact of a physical and nutritional intervention program for frail community-dwelling elderly people over the age of 75. Methods: Ninety-six community-dwelling elderly people (58 women) were randomized to four different groups: i) a physical training program (aerobic, muscle strength, balance), ii) a nutritional intervention program (individually targeted advice and group sessions), iii) a combination of these interventions, and iv) a control group. At baseline subjects were screened for physical performance such as muscle strength, balance, mobility and activities of daily living, as well as nutritional aspects such as energy intake, body weight and fat-free mass. These measurements were repeated immediately after the intervention, which lasted for 12 weeks, and after another 6 months. Results: The intention-to-treat analysis indicated significant improvements in lower-extremity muscle strength in both training groups compared with the nutrition group at 1st follow-up. There were small significant changes for some of the balance measurements in the training group without nutrition treatment. The nutrition intervention did not show any significant results. Conclusions: This study shows the positive effect on lower-extremity muscle strength directly after the intervention. Balance training most probably needs to be more individualized in order to be effective for frail elderly people. Further studies are needed, with larger sample sizes, to investigate the effects of these types of interventions before any further conclusions can be drawn.
