Dynamic alignment of transtibial prostheses is generally
performed based on visual interpretation of gait without the benefit of any
kinetic analysis in the clinic. The aim of this technical note was to present and
discuss the possibilities of assisting dynamic alignment of transtibial
prostheses through visualization of socket reaction moments. TECHNIQUE: Smart
Pyramid (currently Europa) was used to measure the socket reaction moments under
various alignment conditions from an amputee with transtibial prosthesis. The
socket reaction moments were plotted to visualize the effect of alignment changes
on them, and they were clinically interpreted.
DISCUSSION: Socket reaction
moments could complement information available to prosthetists to optimize
prosthetic alignment. They could be used to reduce excessive loading on sensitive
areas, to improve gait stability, or to communicate the outcome of dynamic
alignment with the amputees. Further research is needed to identify the
contribution of kinematics and kinetics for optimal alignment. CLINICAL RELEVANCE: Dynamic alignment of transtibial prostheses is currently tuned
subjectively based on prosthetists' experiences and skills. Socket reaction
moments may potentially provide objective information for prosthetists to align
transtibial prostheses in the clinic.
