Abstract
|
|
|
The purpose of this study was to investigate the effects of age and sex on hand strength and dexterity. 158 normal subjects aged 11 to 75 years in 7 age groups were tested on four tests of hand strength: grip tip pinch, lateral pinch, and palmar
pinch
and two tests of hand dexterity: purdue pegboard and Pennsylvania bi-manual worksample.
The results showed the average scores of grip and pinch strength increased after 11 to 19 years and were relatively stable from 20 to 59 years, and decreased after 60 years. For grip and pinch strength, males are stronger than females in all age
groups
the differences were not significant in 11 to 15 year old group. The scores of purdue pegboard decreased with age over 20 years. with a significant decrease over 60 years. Females performed better than males in general but the differences were
not
significant in age groups. The speeds performing to Pennsylvania bi-manual worksample delayed significantly from 60 years in both sexes. males were faster than females on the assembly of two subtests from 50 years. But for the speeds of the
disassembly,
there were no differences by sex in all age groups.
