Abstract
Our study aimed to examine preoperative differences in strength and balance
between dominant foot (DF) and nondominant foot (non-DF) of individuals
undergoing ligament stabilization surgery in the general population. Patients
with records of preoperative evaluation, including isokinetic dynamometric
strength evaluation, Y-balance test (YBT), and Foot and Ankle Outcome Score
(FAOS), were included in the study. The DF was the preferred leg for accurately
kicking a ball through a goal. Statistical analysis determined the differences
between DF and non-DF and the correlations between muscle strength, balance, and
FAOS. There was no statistically significant difference between DF and non-DF
regarding evertor and invertor muscle strength (p=0.082–0.951). The YBT revealed
no significant difference between the two groups (p=0.082–0.951). There was a
significant correlation between the evertor peak torque and total work deficits
at 30°/s (p=0.022), as well as the evertor peak torque deficit at 120°/s
(p=0.048). No significant differences in muscle strength and balance were found
between DF and non-DF in nonathletes with chronic ankle instability. Peroneal
muscle strength deficit was associated with functional impairment. Tailored
interventions are needed to address limb dominance and muscle strength deficits
in CAI management.
