Effects of a seated upper-extremity exercise program designed to improve cognitive and upper-extremity functions in older females.

[Purpose] The square-touch exercise is an upper-extremity exercise program that can be performed in a seated position and includes cognitive tasks. It was designed to maintain and improve cognitive function in older people. This study aimed to investigate the effects of a three-month square-touch exercise program on the cognitive and upper-extremity functions in older females. [Participants and Methods] The participants were divided into an intervention group of 15 individuals with a mean age of 78.1 ± 5.9 years and a control group of 16 individuals with a mean age of 81.7 ± 6.3 years. The intervention group participated in the square-touch exercise program once a week for three months. The mini-mental state examination, trail-making test, peg test, and grip strength were measured before and after the intervention. [Results] The intervention group showed improved mini-mental state examination scores as well as significantly improved attention and calculation, which are sub-items of the mini-mental state examination. [Conclusion] The square-touch exercise program may be effective for maintaining and improving cognitive function in older females.
