Age-related changes in upper extremity performance of elderly people: a longitudinal study.
The objective of this research was to study age-related changes in the upper extremity performance of healthy community-dwelling elderly people, by using a longitudinal design. In 1995-1996. gross and fine manual dexterity, global performance, motor coordination, grip strength, tactile recognition, two-point discrimination, touch/pressure threshold, and tactile localization of 264 of the 360 subjects initially evaluated in 1992-1993 were reevaluated by using the same upper extremity measuring instruments. Those who did not participate (n = 96) were found to be significantly different from those who participated in the longitudinal study. Although the survivors were younger, more active, and perceived themselves in better health than the nonparticipants, their upper extremity performance significantly decreased in the 3-year period, with a few exceptions. In general, the decline was related to the initial score but not to age.
