a
Double support time expressed as percentage of the gait cycle time (% GC).
*
Pre W/O pacer vs. W pacer, significant at .025 with Bonferroni correction.
#
Pre W/O pacer vs. Post one week W/O pacer.
&
Change score over one week was calculated from scores changes between initial w/o pacer and post one week w/o pacer.
