Functional status of the lower extremities in elderly males. A community study

The purpose of this study was to evaluate the functional status of the lower extremities (FSL) of elderly males from the community and to compare it with the self-assessment of health status (SHS) and ventilatory lung function based on measurement of forced expiratory vital capacity (FVC). The material covered a group of 559 males, age 65-89 years, who are residents of Krakow. The FSL was measured by the length of standing time on one leg (ST). There was a very strong declining trend in the ST with age in the elderly. The ST correlated significantly inversely with age (r=-0.32) and positively with FVC (r=0.29). The FSL was also associated strongly with the SHS score, while body-mass index (BMI) and occupational category (OC) appeared to have insignificant effect. The results of the study suggest that the ST may be used as a crude indicator of the general fitness of the elderly.
