Self reported function and disability in late life: A comparison between recurrent fallers and non-fallers

Purpose. To compare self-reported function and disability between fallers and non-fallers. Method. Self-reported late life function and disability LLFDI were evaluated among 100 elderly persons who live independently in the community in a cross sectional study. The function component evaluates difficulty in performing physical activities in upper and lower extremity and the disability component evaluates limitations in life activities and frequency in taking part in life tasks. Falls, cognitive function, berg balance test BBS, and timed up and go TUG were also evaluated. Results. Eighteen subjects reported one fall F, 11 fell twice or more RF and 71 did not report retrospective fall NF. There were significant differences in overall function of LLFDI between RF and NF 56.8 ± 5.7 vs. 63.7 ± 11.4, P 0.04, mainly due to decreased basic lower extremity function scores 66.2 ± 8.6 vs. 75.3 ± 13.5, P 0.03; no significant differences were found in disability component scores. RF subjects showed high to moderate correlations between overall function of LLFDI, BBS and TUG r 0.77, P 0.006 and r -0.62, P 0.04, respectively, moderate correlation between disability limitation and BBS r 0.60, P 0.05 but weaker with TUG r -0.38, P 0.28. Both BBS and TUG were not correlated with disability frequency r -0.18, P 0.61 and r 0.14, P 0.68, respectively in RF. RF demonstrated high correlation between overall function and disability limitation r 0.76, P 0.007 and low with disability frequency r 0.39, P 0.23. Conclusions. Balance function, self-reported function and disability limitation are strongly associated in RF but not related to the disability frequency, suggesting that the frequency of performing life tasks was not influenced only by functional capabilities.
