Improvement in quality of life of transfemoral amputees: Comparison between 2 types of transfemoral sockets and their influence on functionality and user comfort - A case report.

Abstract

Among the components of lower limb prostheses, a perfectly adapted prosthetic socket is crucial to a successful rehabilitation process. Thus, developing a more comfortable socket could improve the quality of life for transfemoral (TF) amputees. The objective of this case report was to compare 2 TF sockets by evaluating the relationship between socket stiffness and user comfort and their influence on functionality to improve the quality of life of TF amputees. The participant received 2 different sockets: (A) flexible Flixt® socket; (B) conventional socket. He used each socket for 90 days, and after that was submitted to an evaluation at the Gait Laboratory (kinematic and dynamic analyses), completed the Prosthesis Evaluation Questionnaire, and performed Timed Up and Go test, 6-Minute March Test (6MWT), 10-Meter Walk Test, and Amputee Mobility Predictor test. After results were analyzed, the socket that obtained the best degree of satisfaction was assigned to the amputee participant. Combined measures showed that socket B does not considerably change the kinematic parameters neither dynamics parameters namely at stance phase. At Prosthesis Evaluation Questionnaire results, socket A had a better rating than socket B. The results of the Timed Up and Go test, 6MWT, 10-Meter Walk Test, and Amputee Mobility Predictor test obtained identical values, except for the 6MWT. This case report shows evidence of participant satisfaction improvement when using the flexible socket. The study also demonstrates that both sockets are quite effective.
