基于弹力带的神经肌肉训练增强男性排球运动员前交叉韧带重建术后康复以改善平衡和功能表现：一项前瞻性随机临床试验
简介
一项针对30例男性排球运动员（18-30岁）的初步随机对照试验，评估了ACL重建术后晚期（6-12个月）应用基于TheraBand的神经肌肉训练（RNT）对动态平衡和功能表现的影响。实验组（n=15）在常规康复基础上增加8周、每周2次、每次40分钟的TheraBand扰动训练（深蹲、弓步、单腿落地），对照组维持常规活动。结果显示：实验组Y平衡测试综合评分、三…
英文摘要
INTRODUCTION: Persistent neuromuscular deficits following anterior cruciate ligament reconstruction (ACLR) impair dynamic stability and sport-specific performance in volleyball athletes who rely on repetitive jumping and single-leg control. Reactive neuromuscular training (RNT) using TheraBand-mediated perturbations may enhance sensorimotor integration, yet evidence in male volleyball players during late-stage rehabilitation (6-12 months post-ACLR) remains limited. This study evaluated the effects of an eight-week TheraBand-based RNT program on dynamic balance and functional performance. METHODS: A quasi-experimental pre-test/post-test design was used with 30 male volleyball players (18-30 years) allocated to an experimental group (n = 15) or control group (n = 15). The experimental group completed 16 supervised RNT sessions (two 40-minute sessions per week) incorporating progressive TheraBand perturbations during squats, lunges, and single-leg landings. The control group maintained routine activity. Outcomes, assessed on the reconstructed limb, included Y Balance Test composite score (%), triple hop distance (cm), single-leg hop time for 6 m (s), and countermovement vertical jump height (cm). Within-group changes were analyzed with paired-samples t-tests; between-group differences were examined using ANCOVA with baseline adjustment (α = 0.05). RESULTS: The experimental group demonstrated significant improvements in dynamic balance (p < 0.001), triple hop distance (p = 0.022), single-leg hop time (p = 0.015), and vertical jump height (p = 0.014), whereas no significant changes occurred in the control group (all p > 0.05). ANCOVA revealed significant group effects favoring RNT for all outcomes (F(1,27) = 5.67-8.66, p = 0.007-0.024, ηp2 = 0.174-0.243). DISCUSSION: An eight-week TheraBand-based RNT program produced clinically meaningful short-term gains in balance and functional performance. These findings support integration of perturbation-based training into late-stage ACLR rehabilitation in male volleyball players, although longer-term studies are required to confirm retention and return-to-sport benefits.
