From: Mechanical effects of canes on standing posture: beyond perceptual information
Total center of pressure over feet and canes (Total-CoP) and center of pressure at the feet (Feet-CoP) in the medio-lateral (ML) direction for the three force conditions. A Medio-lateral (ML) 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 Standard deviations of the ML component of the Total-CoP motion for the two arm configurations. Each data point represents one participant; different colors indicate different participants. C Feet-CoP in the ML direction against the sum of the forces applied on the canes for each trial. D ML component of the Feet-CoP for each force condition and for the two arm configurations. Each data point represents one participant, different colors indicate different participants.
