Objectives:
To compare the effects of short-foot exercise (SFE) and toe-curl exercise (TCE) on movement control during single-leg landing in individuals undergoing anterior cruciate ligament reconstruction (ACLR).
Design:
Multicenter exploratory randomized controlled trial.
Setting:
One hospital and two outpatient orthopedic clinics.
Participants:
Thirty-eight individuals who had undergone ACLR and demonstrated dynamic knee valgus during a single-leg landing task.
Main Outcome Measures:
Participants were randomized to the SFE or TCE group, performed the allocated exercises daily, and received supervised exercise therapy once weekly for 12 weeks. The primary outcome was hip adduction excursion during single-leg landing. Assessments were conducted at baseline, 6 weeks, and 12 weeks and analyzed using mixed models for repeated measures.
Results:
At 6 weeks, hip adduction excursion was lower in the SFE group than in the TCE group, with a between-group difference of -6.30° (95% confidence interval [CI], -9.19 to -3.41; effect size [ES], -1.41). The between-group difference in change from baseline was -6.98° (95% CI, -9.88 to -4.08; ES, -1.57). At 12 weeks, hip adduction excursion remained lower in the SFE group.
Conclusions:
SFE may facilitate earlier improvement in frontal-plane movement control in patients who have undergone ACLR.
