Executive function was evaluated with the Trail Making Test (TMT)-A, TMT-B and Digit symbol global cognition was assessed with the Mini-Mental State Examination (MMSE). Three hundred and twenty-six older adults (287 women, mean age ± SD, 70.1 ± 5.6) underwent handgrip strength and hand dexterity tests using a hand dynamometer and the Purdue Pegboard Test (PPT), respectively.
We aim to investigate the relationship of handgrip strength and hand dexterity with executive function in physically and mentally healthy community-dwelling older adults. Understanding this association will help identify motor risk factors for impairment of executive function in late adulthood.
An association between handgrip strength, hand dexterity and global cognition is suggested however, it is unclear whether both hand motor functions are associated with executive function, which is important for performing daily activities.
