Fig. 6

Paths and path lengths of the left and right hands for different force instructions differentiated by color. A Exemplary paths of the movements of the left and right hands from two points of view: x–y at the top, z–y below. Each colored line shows one trial in the three force conditions. B Path lengths for the left and right hands per trial plotted against the average force applied to the cane. Each point indicates an individual trial. C Path length for both hands aggregated with respect to force levels and cane configurations. Each data point represents one participant, different colors indicate different participants (*** indicates significance of p < 0.001)
