The softfoot pro at the cybathlon: kinematic, metabolic, and user performance evaluation.

Only one transfemoral amputee pilot was tested, so the findings describe one person and cannot be generalised. No statistical analysis was performed, and the authors describe the work as exploratory rather than comparative. All three feet were tested on the same day, so fatigue may have affected the metabolic results. The foot order was fixed, and one Cybathlon task was excluded after sensor displacement, so the comparison was not randomised or complete. The foot was used with the same semi-active knee and running shoe, and its adaptive sole and energy-return ankle were tested together, so no single component can be credited. The unimpaired comparison subject was a different person and served only as a visual reference, and questionnaire scores came from the same pilot, so they are subjective reference points rather than independent evidence.

The paper states that the funder was the European Research Council. No other author disclosures are given.

Do not read the faster course time or better questionnaire scores as proof the SoftFoot Pro works for transfemoral amputees. The study tested one pilot, used a fixed foot order with the same knee and shoe, and performed no statistical analysis.
