Table 1 Summary data for terrain traversal trials.

Summary data for terrain traversal trials.. The metric in the second column was calculated for each trial of the task named in the first column and averaged within each subject to give an overall subject score. Subject A’s overall subject score for each task (from n = 10 trials per task) is reported in the third column. The fourth column reports mean ± 1 intersubject SD for group T (n = 4 subjects, n = 32 total trials per task). Late swing eversion, late swing dorsiflexion, and late swing plantar flexion were calculated as the maximum eversion, dorsiflexion, and plantar flexion angles, respectively, achieved between 80 and 100% of the swing phase of the relevant task.
