A Comparison of Functional Fitness and Walking Speed with Cognitive Function of Facility-Dwelling Elderly Women: a Cross- Sectional Study

Associations between functional fitness and walking speed in older adults

This cross-sectional study aimed to explore 1) the overall associations between functional fitness and walking speed in older adults and 2) the key functional fitness parameters affecting older adults' walking speeds. A total of 242 apparently healthy older adults finished a 6-m walking speed test at both usual walking speed (UWS) and maximum walking speed (MWS). Functional fitness was assessed using the Senior Fitness Test battery. The results revealed significantly moderate correlations of functional fitness with UWS (r = 0.380) and MWS (r = 0.436). Both age (UWS = -0.332, MWS = -0.324) and dynamic balance and agility (UWS = 0.329, MWS = 0.411) were key indicators of both UWS and MWS. In addition, gender (r = 0.090), aerobic endurance (r = 0.326), and lower body flexibility (r = 0.183) were key fitness indicators of MWS in older adults.

Mobility and cognition at admission to the nursing home - a cross-sectional study

Background

Earlier studies show that the main reasons for admission to long-term nursing home care are cognitive impairment and functional impairments of activities of daily life. However, descriptive evidence of mobility is scant. The aims of this study were to describe mobility at admission to nursing homes and to assess the association between mobility and degree of dementia.

Methods

We included 696 residents at admission to 47 nursing homes in Norway. Inclusion criteria were expected stay for more than 4 weeks and 65 years or older. In addition, younger residents with dementia were included. Residents with life expectancy shorter than six weeks were excluded. Mobility was assessed using the Short Physical Performance Battery (SPPB) and the Nursing Home Life Space Diameter (NHLSD). The Clinical Dementia Rating Scale (CDR) was used to describe the degree of dementia. The associations between mobility and degree of dementia was analysed using the Chi-square and the Kruskal-Wallis test (KW-test). When the KW-test indicated a statistical significant difference, we proceeded with planned group comparisons with the Mann-Whitney U-test. In addition, we performed multiple linear regression analyses to control for potential confounders.

Results

Forty-three percent of the residents were not able to perform the balance test in SPPB. Twenty-four percent of the residents were not able to walk four meters, while only 17.6% had a walking speed of 0.83 m/s or higher. Sixty-two percent of the residents were not able to rise from a chair or spent more than 60 s doing it. The median score on NHLSD area was 22 (IQR 17) and the median score on NHLSD dependency was 36 (IQR 26). Residents with severe dementia had significantly lower levels of mobility than residents with moderate dementia. Cognitive function was associated with SPPB and NHLSD dependency in the adjusted models.

Conclusion

Nursing home residents form a frail, but heterogeneous group both in terms of cognition and mobility at admission. Mobility was negatively associated with cognitive function, and residents with severe dementia had significantly lower levels of mobility than residents with moderate dementia.

Physical Fitness in Older People Recently Diagnosed with Cognitive Impairment Compared to Older People Recently Discharged from Hospital

BACKGROUND/AIMS

There is evidence of an association between cognitive function and physical fitness. The aim of this study was to compare physical fitness in patients with cognitive impairment with a group of older people recently discharged from hospital.

METHODS

A cross-sectional study with 98 patients recently diagnosed with cognitive impairment and 115 patients recently discharged from hospital. Associations between the study group variable and different components in the Senior fitness test were examined, controlling for demographic factors and comorbidity.

RESULTS

The group recently diagnosed with cognitive impairment indicated poorer results on three of six physical fitness components (p < 0.05).

CONCLUSION

Older adults with cognitive impairment are in need of individually tailored physical activity programs to increase the level of physical fitness.

Gait speed in ambulant older people in long term care: a systematic review and meta-analysis

BACKGROUND

Gait speed, recently proposed as the sixth vital sign of geriatric assessment, is a strong predictor of adverse outcomes. Walking faster than 1.0 m/s is associated with better survival in community-dwelling older adults, and a recent meta-analysis of older adults in clinical settings estimated usual gait speed to be 0.58 m/s. Here, we aimed to review gait speed values for long term care residents.

METHODS

Relevant databases were systematically searched for original research studies published prior to December 2012. Inclusion criteria were participants living in long term care, mean age >70 years, and gait speed measured over a short distance. Meta-analysis determined gait speed data adjusting for covariates including age, sex, and cognition.

RESULTS

Final data included 2888 participants from 34 studies. The percentage of residents ineligible because of inability to mobilize was stated in only 1 study. Of the 34 studies, 22 reported cognitive status using the Mini-Mental State Examination. Usual pace and maximal pace gait speeds were determined separately using a random effects model. No association between gait speed and covariates was found. Usual pace gait speed was 0.475 m/s (95% confidence interval 0.396-0.554) and maximal pace was 0.672 m/s (95% confidence interval 0.532-0.811).

CONCLUSIONS

In ambulant older people in long term care, gait speed is slow but remains functional. However, since many residents are likely to have been ineligible to participate in assessments, these results cannot be generalized to the long term care population as a whole.
