U. Sonn et al., INSTRUMENTAL ACTIVITIES OF DAILY LIVING-RELATED TO IMPAIRMENTS AND FUNCTIONAL LIMITATIONS IN 70-YEAR-OLDS AND CHANGES BETWEEN 70 AND 76 YEARS OF AGE, Scandinavian journal of rehabilitation medicine, 27(2), 1995, pp. 119-128
The aim of this study was to analyse in particular dependence in instr
umental daily life activities (I-ADLs) and its association with physic
al impairments and functional limitations in the elderly. The study wa
s based on cross-sectional data on 70-year-olds (n = 602) and longitud
inal data on subjects followed up to the age of 76 (n = 371). Persons
dependent in ADL had lower values in maximum walking speed, grip stren
gth, knee extensor strength, stair climbing capacity and in forward re
ach, compared with those who were independent in ADL. Walking speed in
both women and men and sight impairment in men had the greatest influ
ence on dependence in ADL. Possible critical levels for disability in
ADL are discussed, as persons who developed dependence between 70 and
76 already had a lower capacity in walking speed and knee extensor str
ength at age 70 than persons who retained their independence in ADL.
