Abstract
© 2019, Siriraj Medical Journal. Objective: To examine the temporal-spatial characteristics of transfemoral amputees using three prosthetic knees available in Thailand. In addition, the estimated vertical Ground Reaction Force (vGRF) was explored, in particular the graphical differences in the M-shape of the vGRF pattern amongst each of the knees and the sound limb. Methods: Three transfemoral amputees were fitted with three different prosthetic knee joints (Chulalongkorn University (CU) Polycentric Knee Joint, Prosthesis Foundation Knee, Otto Bock 3R20) and performed walking trials while the vGRF and temporal-spatial parameters were collected for all participants. Results: Similarities existed amongst GRF metrics across all prosthetic knees. Stance and swing time in the CU Polycentric Knee Joint was similar to that of the sound limb. Walking speeds were highest in the Otto Bock 3R20 and lowest in the Prosthesis Foundation Knee. Conclusion: This preliminary pilot testing revealed similarities amongst all three prosthetic knees. Future research with more participants and additional analysis could further elucidate characteristics of these prosthetic knees.
