The objective of this study was to demonstrate how a load
cell and force-moment curves can be used outside of a gait lab to directly
measure and evaluate the transverse plane loading moment on transtibial residual
limbs. TECHNIQUE: A load cell was attached distally to the socket of three
transtibial amputees who walked a straight path and a circle of 3.048-m diameter
with the prosthetic foot both inside and outside the curved path. DISCUSSION:
Compared to straight path walking, transverse plane moment decreased when the
foot was on the outside of the curved path. When the foot was on the inside, the
moment did not exceed that for straight path walking for two participants;
maximum transverse moment was approximately 0.15 N m/kg of body mass.
Force-moment curves indicated that each participant's gait was unique, but
underlying similarities were observed with respect to each of the three
conditions. CLINICAL RELEVANCE: A load cell in conjunction with curved and
straight path walking and force-moment curves can be used outside of a gait lab
to measure and examine the transverse plane loading on the residual limb.
