Fig. 3From: Retraining walking over ground in a powered exoskeleton after spinal cord injury: a prospective cohort study to examine functional gains and neuroplasticityWalking measures at the end of training. The height of the bars represent the mean, with the individual participant scores in circles offset to show all data (n = 11). Filled circles represent those with motor incomplete injuries. a. Walking speed as measured during a modified 10-m walk test (10MWT). b. Distance covered during the 6-min walk test (6MWT). c. The maximum distance walked without a rest in 1 h. Ten data points shown here because P5 dropped out before a maximum distance was attempted. d. The effort of walking estimated with the Physiological Cost Index (PCI) while performing the 6MWT, expressed as a fraction of the PCI for the 6-min wheelchair test in the same personBack to article page
