The relationships of motor function, education, age and cognitive function to the physical activities of daily living.
The physical activities of daily living are a final outcome of many functions and dependent on many factors. This study was aimed at exploring the relationships of motor function, dementia, education, age, and cognitive function to the physical activities of daily living in 67 elderly people residing in an institution in Taegu, Korea. Their mean ( +/- SD) age was 75.6 +/- 8.1 and 24 (35.8%) were men. Twenty-eight (41.8%) were classified as having definite cognitive impairment, 17 (25.4%) as having questionable impairment, and 22 (32.8%) as having no impairment by the Korean version of the mini-mental state examination. Of the aforementioned 5 variables, the Motoricity Index could account for 42% of the Barthel Activities of Daily Living variance. If the modified Blessed Dementia Rating Scale was included in the multiple regression, the accountable portion of the Activities variance increased by 4% only. Using the 2 variables, regression equation, y = 0.248 x chi 1-0.359 x chi 2-6.250 (y: Barthel Activities of Daily Living score, chi 1: Motoricity Index score, chi 2: modified Blessed Dementia Rating Scale score) could be produced. Conclusively, the physical activities of daily living of elderly people could be related mainly with motor function of the limbs and severity of dementia.
