The multifinger force deficit (MFFD) is the decline in generated by an individual finger as number of fingers contributing to action increased. It has been proposed that a measure neural sufficiency rather than muscle status, it provides means detecting individuals at risk cognitive decline. Age-related deficits central drive exert disproportionate impact on rate which can be generated. We examined whether MFFD derived from maximum generated, more sensitive differences one calculated using level force.

Association between Present Teeth and Muscle Strength in Older People in Korea

Journal of Personalized Medicine, Год журнала: 2022, Номер 12(7), С. 1163 - 1163

Опубликована: Июль 18, 2022

Background: As the world population continues to age, interest in muscle strength loss older people is increasing. This study aimed confirm association between present teeth and Korea. Methods: Using data extracted from 2014–2019 Korea National Health Nutrition Examination Survey, we analyzed 5136 aged 65–79 years. The were based on 20 teeth, which criteria for comfortable mastication. of risk low according was assessed using multiple logistic regression analysis, confirmed by dividing into subgroups sex. Results: prevalence 17.87% among all participants. Multiple analysis teeth; a significant found even model covariates adjusted (odds ratios (OR) = 1.35; 95% confidence interval (CI): 1.13–1.61). Subgroup revealed both sex (Men, OR 1.41; CI: 1.02–1.95; Women, 1.31; 1.06–1.6). Conclusion: An These results indicate that importance oral hygiene management should be emphasized prevent people.

Abstract Background The multifinger force deficit (MFFD) is the decline in generated by each finger as number of fingers contributing to an action increased. It has been shown associate with cognitive status. Aims aim was establish whether a particularly challenging form grip dynamometry, that provides minimal tactile feedback via cutaneous receptors and requires active compensation for reaction forces, will yield MFFD more sensitive Methods Associations between measures motor function, status (Montreal Cognitive Assessment [MoCA]) latent components function (derived from 11 tests using principal component analysis), were estimated cross-sectionally generalized partial rank correlations. participants ( n = 62) community dwelling, aged 65–87. Results Approximately half unable complete dynamometry task successfully. demarcated individuals who could perform those not. Among complied requirements, negatively correlated MoCA scores—those highest scores tended exhibit smallest deficits, vice versa. There corresponding associations function.

Conclusions outcomes add weight assertion deficits production during tasks dysfunction.

The Mediating Role of Cognitive Function in the Association between Grip Strength and Depression among Chinese middle-aged and elderly adults: A Cross-Sectional Study

Research Square (Research Square), Год журнала: 2024, Номер unknown

Опубликована: Апрель 8, 2024

Objective This study investigates the associations and mediating pathways between grip strength, cognitive function, depression in middle-aged elderly individuals China. Methods Utilizing data from 2011 China Health Retirement Longitudinal Study (CHARLS), we employed logistic regression mediation analysis to examine relationships factors depression, while adjusting for potential confounders. Results The included 6,841 participants, of whom 1,734 (25.35%) exhibited symptoms depression. Our findings indicate that weak strength is significantly associated with an increased risk (OR: 1.57, 95% CI: 1.32–1.87) among population. Conversely, good function was found be protective against 0.94, 0.93–0.95). revealed indirectly affects through accounting 9.4% total effect −0.008, -0.013, − 0.004). Specifically, abilities such as calculation, memory, orientation were identified significant mediators relationship Conclusion highlights adequate can mitigate association These insights provide valuable guidance clinical practitioners diagnosis management emphasizing importance assessing function.
