A cross-sectional study of the association between dynapenia and higher-level functional capacity in daily living in community-dwelling older adults in Japan

Abstract: BackgroundThere 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.MethodsParticipants included 123 community-dwelling older adults (31 men, 92 women,) aged 65 years or older (75.0 ± 5.3 years) who were independent in I… Show more

“…The TMIG‐IC score is used to assess higher‐level functional capacity, and the mean score in the present study was 11.5 points. In the general population, mean TMIG‐IC scores have been reported as 11.8 at a mean age of 75.4 years, and are consistent with the present results . However, because our patients were younger than the participants in those studies, their higher‐level functional capacity might be lower than that of healthy individuals of the same age.…”

“…We found a statistically significant association between dynapenia and a decline of higher‐level functional capacity in men. In healthy individuals, dynapenia has been reported to correlate with a decline in higher‐level functional capacity . The link between dynapenia and higher‐level functional capacity might depend on reduced muscle strength because of age‐related morphological and neurological changes in skeletal muscles, which ultimately results in decreased physical activity and limitations in movements associated with daily activities .…”

“…With aging, the aforementioned factors related to muscle strength appear to diminish, resulting in a decline in muscle strength that occurs more markedly than the decline in muscle mass 27 . Thus, in this age group, muscle mass is more strongly correlated with skeletal muscle strength in the upper limbs.…”

“…These modifications that occur in the muscular system due to the aging process impair the performance of motor skills, directly altering the ability of elderly individuals to perform instrumental and basic activities of daily living and making it difficult to adapt to the environment in which they live 27 . Thus, for the population of this study, this evaluation may indicate important aspects relating to the physical performance, health and quality of life of women.…”

“…First, the loss of muscle mass plays a critical role in unintentional weight loss of frailty in the elderly. Second, age-related loss of muscle strength, commonly referred as dynapenia, was associated with both sarcopenia and frailty [8]. Sarcopenia and frailty had the sensitivity and specificity for dynapenia of 33 and 89%, 17 and 98%, respectively.…”
