前交叉韧带重建术后6至12个月改良星形偏移平衡测试表现的变化
简介
这是一项纵向队列研究，纳入115例前交叉韧带（ACL）重建患者，评估术后6个月和12个月时改良星形偏移平衡测试（mSEBT）表现的变化，并分析年龄、性别、移植物类型及活动水平的影响。 关键发现：术后12个月时，患侧肢体mSEBT评分较6个月显著提高（p<0.005），但肢体对称指数（LSI）无显著变化。92%的患者在术后6个月时即达到复合评分>90%腿长的阈…
英文摘要
OBJECTIVES: To determine the change in modified star excursion balance test scores in patients between 6 and 12 months following anterior cruciate ligament (ACL) reconstruction and the change in the proportion of patients who met recommended thresholds at each timepoint. A secondary aim was to assess whether change over time differed according to age, sex, graft type or activity level. DESIGN: Longitudinal cohort. SETTING: Orthopaedic Clinic. PARTICIPANTS: 115 patients that completed 6- and 12-month testing after ACL reconstruction. MAIN OUTCOME MEASURES: Modified star excursion balance test scores (composite and individual reach scores). RESULTS: There was a significant increase of test scores for the surgical limb at 12-months compared to 6-months (p < 0.005) with no differences in limb symmetry index. Most patients (92%) reached threshold composite scores >90% equivalent to individual leg length at 6-months. This proportion did not change at 12-months. Patient-related factors had no effect on change in test scores across time. CONCLUSIONS: The modified star excursion balance test may be more applicable to assess dynamic balance performance 6-months post-surgery. Almost all patients met pre-determined criteria for dynamic balance performance by 6-months following surgery. There was no impact of patient age, sex, graft type or activity level on change in performance between 6- and 12-months.
