Age-Related Attenuation of Dominant Hand Superiority
BACKGROUND The decline of motor performance of the human hand-arm system with age is well-documented. While dominant hand performance is superior to that of the non-dominant hand in young individuals, little is known of possible age-related changes in hand dominance. We investigated age-related alterations of hand dominance in 20 to 90 year old subjects. All subjects were unambiguously right-ha...
متن کاملHand Function Related to Age and Sex
Objectives: The purpose of this study was for evaluation of relationship between hand function and age, sex by Jebson Taylor Test.This study determined whether age might be a factor when associated with sex. Methods: In this study Jebson Taylor was evaluated on hand in 180 normal males and females (0.50% male, 0.50% female) in each of the following 7 subtest in 3 age groups: (15-25), (35-45)...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولPreservation of neuronal number despite age-related cortical brain atrophy in elderly subjects without Alzheimer disease.
Cerebral volume loss has long been associated with normal aging, but whether this is due to aging itself or to age-related diseases, including incipient Alzheimer disease, is uncertain. To understand the changes that occur in the aging brain, we examined the cerebral cortex of 27 normal individuals ranging in age from 56 to 103 years. None fulfilled the criteria for the neuropathologic diagnosi...
متن کاملComparing Dominant and Non-Dominant Hand Performance with Force Changes In a Two-Hand Equilibrium Task: A Challenge to Dominant Hand Theories
Objective: Although most studies believe that the dominant hand performs better than the non-dominant hand in performing various tasks, there is still the challenge among researchers as to why the non-dominant hand performs better than the dominant hand in certain situations and tasks. The aim of this study was to compare dominant and non-dominant hand performance with force changes in a two-ha...
