The investigation of the dynamic joint stiffness behavior may help to understand the lower limb joints\u2019 contribution to these changes. This study aimed to investigate the dynamic stiffness of lower limb joints in response to the increased load carried while walking. Thirteen participants walked in two conditions: unloaded (an empty backpack) and loaded (the same backpack plus added mass corresponding to 30% of body mass). Dynamic stiffness was calculated as the linear slope of the regression line on the moment\u2013angle curve during the power absorption phases of the ankle, knee, and hip in the sagittal plane. The results showed that ankle (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.002) and knee (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u2009.001) increased their dynamic stiffness during loaded walking compared with unloaded, but no difference was observed at the hip (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.332). The dynamic stiffness changes were different among joints (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u2009.001): ankle and knee changes were not different (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u2009.992), but they had a greater change than hip (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u2009.001). The nonuniform increases in lower limb joint dynamic stiffness suggest that the ankle and knee are critical joints to deal with the extra loading.\n
