Time series of across-subject average force profiles for each of four shear force (FS) directions (with standard error shades). All forces are normalized to the initial steady state values of FS in each condition; note that this is different from analysis, in which all forces are normalized to their own initial steady state values. Dashed line: task variable (FS); solid line: non-task variable (FN). NFU – normalized force unit.
