The aim of this study was to determine whether the internal model regulating grip force (GF)/load force (LF) coordination during a brisk load increase is preserved when the lower extremities produce a perturbation during a single step-down task. We observed the coordination of the vertical ground reaction force (vGRF). GF and LF while holding a handheld object during a single step-dow... https://www.markbroyard.com/mega-pick-revlon-colorstay-lip-liner-plum-665-discount-top-super/
