The socket reaction moments are directly measured at the base
of a socket and may be useful for fitting a prosthesis. Previous studies have
focused on the effect of prosthetic alignment changes on them. The aim of this
study was to explore their range at clinically perceived optimal alignment by
investigating the individual differences. TECHNIQUE: In total, 11 amputees using
unilateral transtibial prostheses with solid-ankle-cushion-heel (SACH) feet were
recruited. The socket reaction moments were measured using a custom instrumented
prosthesis alignment component and plotted. Eight variables that were related to
their magnitude (N m/kg) and timing (% stance of event) as well as cadence
(steps/minute) were calculated for each amputee. Their mean, standard deviation,
maximum value, minimum value, and range were subsequently analyzed. DISCUSSION:
This study may serve as a foundation to explore the range of individual
differences in socket reaction moments in transtibial prostheses. CLINICAL
RELEVANCE: Socket reaction moments can be conveniently measured in the clinical
setting. Prosthetists could potentially use them as one of the criteria to align
prosthesis in addition to observational gait analysis and amputees perception.
