Description
Hajun Lee and co-authors test whether aging makes the force of a two-hand grip less smooth, in a study from 2026. Older adults are known to grip with more error and wobble at low force. What was not clear is whether the path of the force over time also turns rougher with age.
Fifteen young adults and fifteen older adults gripped with both hands at ten percent of their max strength, with and without sight of the task. The team scored error, spread, smoothness, and how well the two hands matched. Older adults showed rougher force in both sight setups, and the smoothness score split the two age groups cleanly. In older adults, rougher force also tracked with more error and spread.
