The aim of this study was to examine the effect of isometric muscle strength
of the lower and upper extremities on independence in activities of daily living
in older people living in nursing homes.
The study involved 111 voluntary older persons
living in 3 nursing homes, who met the inclusion criteria. The sociodemographic characteristics of the participants were recorded. Muscle strength
of the shoulder flexors, extensors, abductors, external rotators, elbow flexors and extensors in the upper extremities, and hip flexors, extensors, abductors, knee flexors, and extensors in the lower extremities were evaluated with an isometric dynamometer. The level of independence in the daily living activities of the older persons
was assessed with the Functional Independence
Measure in this study.
A significant difference was determined in the muscle strength
of the shoulder and elbow extensor in the right side for both males and females (P
< .05). In both genders, a statistically significant relationship was found between functional independence
and the muscle strength
of the shoulder flexor, extensor, abductor, elbow flexor, hip extensor, and knee flexor in both sides of the extremities (P
The muscle strength
values of the upper extremities were more associated with the activity level of daily living than the muscle strength
of the lower extremities in older persons
. The level of daily living activities was seen to be more affected by the muscle strength
values of the older females than the males.
