We investigated strategies of healthy elderly participants (74–84 years old) during prehension and transport of an object with varying degrees of fragility. Fragility was specified as the maximal normal force that the object could withstand without collapsing. Specifically, kinetic and kinematic variables as well as and force covariation indices were quantified and compared to those shown by young healthy persons (19–28 years old). We tested three hypotheses related to age-related changes in… CONTINUE READING
