Bilateral Kinematic and Kinetic Data of Two Prosthetic Designs: A Case Study: PDF Only

ABSTRACT

This article discusses a comparison of ankle kinematic and kinetic data and the energy efficiency of two different prosthetic designs for a 16-year-old girl with bilateral transtibial amputations. Kinematic and kinetic data were obtained by having the patient walk at a normal, self-selected walking speed and wear the old prosthetic and then the new prosthetic. With the new prosthetic design, we noted that the patient displayed significantly greater sagittal plane ankle motion and ankle power, resulting in a higher ratio of energy efficiency. Because the patient has bilateral below-knee amputations, the changes noted cannot be attributed to an uninvolved extremity's compensating for an involved extremity.
