Abstract

The objective of this study was to develop a prototype of transfemoral prosthesis for swimming focused on the leg joint motion. This prosthesis has (i) an ankle joint and a knee joint which provide appropriate leg motion and (ii) a prosthesis whose appearance is sufficiently similar to an actual one. In order to confirm the validity of the developed prosthesis, a swimming experiment, in which a subject swimmer swam in a pool with the developed prosthesis attached, was conducted. The joint angles of the lower limbs were measured and an evaluation with questionnaires was performed. The validity of the proposed prosthesis was experimentally confirmed since the movable joints with appropriate spring yielded a better swimming performance and more comfort to the swimmer.
