Framework for a short muscle function battery using electronic handgrip dynamometry and accelerometry in older adults.
Background: Electronic handgrip dynamometry and accelerometry enables novel opportunities to collect additional attributes of muscle function beyond just maximal strength, but some muscle function attributes may already be related, which may warrant discerning these attributes into a short muscle function battery (SMFB).
Objectives: We sought to determine the multivariate relationships between maximal strength, asymmetry, submaximal control, rate of force development, bimanual coordination, fatigability, and contractile steadiness in older adults.
Design: A cross-sectional design was used for this investigation.
Setting: Laboratory.
Participants: The analytic sample included 121 generally healthy older adults aged 70.7 ± 4.7 years.
Measurements: Electronic handgrip dynamometry and accelerometry measured strength, asymmetry, submaximal control, rate of force development, bimanual coordination, fatigability, and contractile steadiness. The handgrip variables were standardized before they were included in a factor analysis. Factors with eigenvalues >1.0 were kept. Items within a factor with a loading |>0.30| were similarly retained.
Results: There were 3 factors retained with eigenvalues of 1.88, 1.56, and 1.10. The first factor (functional strength), which explained 39.9 % of the variance, included strength, submaximal control, and rate of force development. Factor 2 (lateral function), which explained 35.8 % of the variance, included asymmetry and bimanual coordination. The third factor (muscle endurance), which explained 24.3 % of the variance, included fatigability and contractile steadiness.
Conclusions: Our findings suggest the surfacing of themes in the additional muscle function measures, thereby providing framework for a SMFB. More research is needed for electronic handgrip dynamometry and accelerometry derived muscle function on health before consideration of implementation in clinical practice.
期刊介绍：
The Journal of Frailty & Aging is a peer-reviewed international journal aimed at presenting articles that are related to research in the area of aging and age-related (sub)clinical conditions. In particular, the journal publishes high-quality papers describing and discussing social, biological, and clinical features underlying the onset and development of frailty in older persons. The Journal of Frailty & Aging is composed by five different sections: - Biology of frailty and aging In this section, the journal presents reports from preclinical studies and experiences focused at identifying, describing, and understanding the subclinical pathophysiological mechanisms at the basis of frailty and aging. - Physical frailty and age-related body composition modifications Studies exploring the physical and functional components of frailty are contained in this section. Moreover, since body composition plays a major role in determining physical frailty and, at the same time, represents the most evident feature of the aging process, special attention is given to studies focused on sarcopenia and obesity at older age. - Neurosciences of frailty and aging The section presents results from studies exploring the cognitive and neurological aspects of frailty and age-related conditions. In particular, papers on neurodegenerative conditions of advanced age are welcomed. - Frailty and aging in clinical practice and public health This journal’s section is devoted at presenting studies on clinical issues of frailty and age-related conditions. This multidisciplinary section particularly welcomes reports from clinicians coming from different backgrounds and specialties dealing with the heterogeneous clinical manifestations of advanced age. Moreover, this part of the journal also contains reports on frailty- and age-related social and public health issues. - Clinical trials and therapeutics This final section contains all the manuscripts presenting data on (pharmacological and non-pharmacological) interventions aimed at preventing, delaying, or treating frailty and age-related conditions.The Journal of Frailty & Aging is a quarterly publication of original papers, review articles, case reports, controversies, letters to the Editor, and book reviews. Manuscripts will be evaluated by the editorial staff and, if suitable, by expert reviewers assigned by the editors. The journal particularly welcomes papers by researchers from different backgrounds and specialities who may want to share their views and experiences on the common themes of frailty and aging.The abstracting and indexing of the Journal of Frailty & Aging is covered by MEDLINE (approval by the National Library of Medicine in February 2016).
