Total center of pressure (Total-CoP) and center of pressure at the feet (Feet-CoP) in the anterior–posterior (AP) direction for different cane conditions. A Anterior–posterior (AP) component of the Total-CoP motion with respect to the sum of the forces applied on the canes; each data point is the average of one trial. Filled circles represent the planar configuration, empty circles the tripod configuration. B Feet-CoP in the AP direction against the sum of the forces applied on the canes for each trial. C Standard deviations of the AP component of the Total-CoP motion for the two cane configurations. Data are pooled together for each force condition. Each data point represents one participant; different colors indicate different participants. D AP component of the standard deviation of the Feet-CoP for each force condition and for the two cane conditions. Each data point represents one participant, different colors indicate different participants. (*** indicates significance of p < 0.001)
