There are many reports that dynapenia, sarcopenia and frailty each have associations with bodily function or with Instrumental Activities of Daily Living (IADL). However, studies that compare all three conditions and their effects on IADL are lacking. The purpose of this study is to examine associations of sarcopenia, frailty, and dynapenia with IADL. Participants included 123 community-dwelling older adults (31 men, 92 women,) aged 65 years or older (75.0±5.3 years) who were independent in IADL. In terms of physical function …

5 Introduction: Sarcopenia, a condition characterized by decreased skeletal muscle mass, has 6 increasingly been attracting attention in Japan, which has an aged society. The association 7 between chronic low back pain (CLBP) and muscle mass is important. This study aimed to 8 investigate the effect of exercise therapy for CLBP with or without sarcopenia. 9 Methods: This study was a prospective cohort study. Patients who were aged> 65 years 10 during 2017–2018 and had CLBP, with pain lasting> 12 weeks and pain …

This study aimed to investigate risk factors for sarcopenia in community-dwelling older adults visiting regional medical institutions. We retrospectively analyzed medical records of 552 participants (mean age: 74.6±6.7 years, males 31.3%) who underwent body composition evaluation between March 2017 and December 2018 at one of 24 medical institutions belonging to the Kadoma City Medical Association in Japan. We collected the participant's characteristics and laboratory data. Sarcopenia was diagnosed according to the …

Abstract Purpose The Asia Working Group for Sarcopenia 2019 (AWGS) recommended using the calf circumference (CC) cut-off values to facilitate the case-finding of sarcopenia. However, the validity of the proposed cut-offs has not been examined in older patients with stroke. This study investigated the validity of the AWGS-recommended CC cut-off values for identifying sarcopenia among older patients with stroke. Materials and methods This cross-sectional study enrolled consecutive patients with stroke, aged 65 years and older, admitted …

Recent epidemiological evidence suggests that effects of cardiovascular risk factors may vary depending on sex and age. In this study, we assessed the associations of metabolic syndrome (MetS) with sarcopenia and its components in older adults, and examined whether the associations vary by sex and age. We also tested if any one of the MetS components could explain the associations. We conducted a cross-sectional analysis of the baseline data from the cohort study conducted in Kashiwa city, Chiba, Japan in 2012 which …

Objective To determine whether there was a difference in balance, proprioception, and skeletal muscle mass among patients who undergo hip fracture surgery relative to and elective total hip replacement (THR). Methods Thirty-one THR patients were enrolled. The patients were categorized into two groups: fracture group (n= 15) and non-fracture group (n= 16). Berg Balance Scale (BBS) was used to balance the proprioception of the hip joint while a joint position sense (JPS) test was used to evaluate it. Skeletal muscle mass was …

We, the Guest Editors of this special issue, are proud to publish 16 articles on sarcopenia from six Asian countries, including seven articles from Japan, four from Taiwan, two from Hong Kong, and one each from Korea, China, and Thailand. We searched PubMed using the key words “sarcopenia” and “human,” and found 97 original articles that were published in English in 2013 (from January to November). Among the articles, 17 were from Asian countries. Thus, researchers in Asian countries have contributed significantly to sarcopenia …

Background Sarcopenia is defined as a progressive and generalized loss of muscle mass with either a loss of muscle strength or a loss of physical performance but there is no recommendation regarding the diagnostic tools that have to be used. In this study, we compared the prevalence of sarcopenia assessed using different diagnostic tools. Methods To measure muscle mass, muscle strength and physical performance, we used for each outcome two different diagnostic tools. For muscle mass, we used Dual Energy X-Ray …

This cross-sectional study investigated the association between osteoporosis, grip strength, and skeletal muscle mass in community-dwelling older women. Data obtained from 265 older women who participated in a community-based health check survey (Tarumizu Study) were analyzed. Face-to-face interviews with participants revealed their history of osteoporosis. Appendicular skeletal muscle mass was assessed through bioelectrical impedance analysis, and appendicular skeletal muscle index was calculated. Dominant grip …
