短足运动与脚趾抓握运动对ACL重建术后单腿落地时动作控制影响的比较：一项探索性随机对照试验
简介
这项多中心探索性RCT纳入38例ACL重建后单腿落地时存在动态膝外翻的患者，在均每周接受1次监督下运动治疗的基础上，随机每日行短足运动或脚趾卷曲运动12周，主要结局为单腿落地时的髋内收位移。6周时短足运动组髋内收位移较脚趾卷曲运动组低6.30°（95%CI -9.19~-3.41，ES -1.41），较基线变化的组间差为-6.98°（95%CI -9.88~…
英文摘要
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.
