The objective of this study was to evaluate the effects of lateral and medial
wedges on postural sway. Twenty healthy volunteers (mean age range of
28.45+/-3.34) participated in the study. They stood barefoot with eyes open or
closed on each of the three surfaces: 10 degrees lateral wedges, 10 degrees
medial wedges, and no wedges. Force platform data were collected and the mean and
root mean square (RMS) distance, range, and velocity and the mean frequency of
the center of pressure (COP) were calculated in the anterior-posterior (AP) and
medial-lateral (ML) directions. Standing on both lateral and medial wedges was
associated with improved postural stability seen through the decreased mean and
RMS distance of COP displacement in ML direction. The results of this study
suggest that standing on either lateral or medial wedges might enhance postural
control in standing.
