The modular socket system in a rural setting in Indonesia.

The sample was small and selected from existing prosthetic users, so it may not represent all people with lower-leg amputation. The same team fitted the prosthesis and assessed outcomes, so participants and researchers were not blinded. Participants were recruited from clinic users who presented with discomfort, which may bias satisfaction and function scores. Questionnaires required multiple translations, so wording may not have been standardised. No direct cost comparison with the previous prosthesis was possible because the system was not commercially available locally. The sponsor supplied materials and equipment, which may influence reporting of feasibility.

Össur sponsored the material and equipment needed to make the prostheses. The authors declared no other financial support for the article.

Do not conclude that the modular socket improves walking or daily function. Walking speed and distance did not change significantly over follow-up, and reported use and comfort scores decreased.
