(Left) Prosthesis-side stance time and stance time symmetry averaged across all participants for the three post-test conditions. The post-test compared the three different control parameter sets that were determined after tuning without feedback (No FB Post), with self-selected stance time feedback (SS FB Post), and with increased stance time feedback (Inc FB Post). There was no significant difference across conditions. (Right Top) Knee angle averaged across all participants for the three post-test conditions. (Right Bottom) One representative TFA participant’s stance time, stance time symmetry, and knee angle profile in the three post-test conditions. Although there was no significant difference across conditions, the result of the individual analysis showed that roughly half the participants experienced a significant difference in the stance time or stance time symmetry. We observed that these participants had variations in their knee angle profiles for the different tuning conditions as representatively shown in the bottom right
