Abstract
Many elderly persons feel anxiety during daily life due to a decrease in walking speed, a fear going up and down stairs, fall by balance capacity decline. Although ankle joint mobility decreases with aging, the relation to activities of daily living (ADL) hasn't been investigated so much. PURPOSE: The purpose of this study was to investigate the relation between ankle joint mobility and ADL ability of elderly health club participants, and to examine whether the ADL ability is improved to when ankle joint mobility is improved. METHODS: Forty elderly people (age 60 ± 12.9 yrs., height 153.2 ± 6.10 cm, weight 52.1 ± 6.87 kg) health club participants participated in this study. Knee to wall (KTW [cm]; ankle mobility, right and left ankle), timed up and go test (TUG [sec.]) and one leg standing test with open eye (OLS [sec.], ADL function, right and left ankle), and stairs up and down time (SU and SD [sec.]; ADL) were measured before and after health club intervention. Coefficient of correlation between measurements before intervention was calculated. The effect of intervention was considered from the measurements before and after intervention using paired t-test for TUG, 2 factor ANOVA for KTW (each left and right) and SU&SD, and Wilcoxon signed rank test for OLS (each left and right). RESULTS: Measurement results before intervention were KTW (average of right and left ankle) 12.5±3.1, TUG 6.7±2.25, OLS (average of right and left ankle) 32.0±20.16, SU 3.6±2.33, and SD 5.4±3.46.The coefficient of correlation with the KTW were TUG -0.674, OLS 0.412 (Spearman's rank correlation coefficient), SU -0.483, and SD -0.579. Measurement results after intervention were KTW (average of right and left ankle) 13.3±2.75, TUG 6.1±1.94, OLS (average of right and left ankle) 38.8±20.34, SU 4.0±3.66, and SD 4.5±3.07.KTW, OLS and SD were improved significantly (p<.01, respectively). CONCLUSIONS: The relation between the ankle joint mobility and ADL ability of elderly health club participant was observed. Improvement of ADL ability was caused by improvement of ankle joint mobility by health club intervention.
