^a

Independent variables listed in order of entry to multiple regression analysis.

^b

simple correlation

^c

sr²=square of the simpartial correlation indicating the unique variance accounted for by the individual independent variable

MTPJ angle=metatarsophalangeal joint angle

extensor/flexor=ratio of toe extensor/flexor muscle strength

DF ROM=ankle dorsiflexion range of motion

EV ROM=subtalar joint eversion range of motion

NS=not significant
