BACKGROUND
After anterior cruciate ligament reconstruction (ACLR), quadriceps strength must be maximised as early as possible.
OBJECTIVES
We tested whether local vibration training (LVT) during the early post-ACLR period (i.e., ∼10 weeks) could improve strength recovery.
METHODS
This was a multicentric, open, parallel-group, randomised controlled trial. Thirty individuals attending ACLR were randomised by use of a dedicated Web application to 2 groups: vibration (standardised rehabilitation plus LVT, n=16) or control (standardised rehabilitation alone, n=14). Experimenters, physiotherapists and participants were not blinded. Both groups received 24 sessions of standardised rehabilitation over ∼10 weeks. In addition, the vibration group received 1 hour of vibration applied to the relaxed quadriceps of the injured leg at the end of each rehabilitation session. The primary outcome - maximal isometric strength of both injured and non-injured legs (i.e., allowing for limb asymmetry measurement) - was evaluated before ACLR (PRE) and after the 10-week rehabilitation (POST).
RESULTS
Seven participants were lost to follow-up, so data for 23 participants were used in the complete-case analysis. For the injured leg, the mean (SD) decrease in maximal strength from PRE to POST was significantly lower for the vibration than control group (n=11, -16% [10] vs. n=12, -30% [11]; P=0.0045, Cohen's d effect size=1.33). Mean PRE-POST change in limb symmetry was lower for the vibration than control group (-19% [11] vs. -29% [13]) but not significantly (P=0.051, Cohen's d effect size=0.85).
CONCLUSION
LVT improved strength recovery after ACLR. This feasibility study suggests that LVT applied to relaxed muscles is a promising modality of vibration therapy that could be implemented early in ACLR.

背景
在前交叉韧带重建（ACLR）后，必须尽早将股四头肌力量最大化。
目的
我们测试了在 ACLR 后早期（即约 10 周）进行局部振动训练（LVT）是否可以改善力量恢复。
方法
这是一项多中心、开放、平行组、随机对照试验。30 名接受 ACLR 的患者通过专用 Web 应用程序随机分为 2 组：振动组（标准康复加 LVT，n=16）或对照组（标准康复，n=14）。实验者、物理治疗师和参与者均未设盲。两组均在约 10 周内接受 24 次标准康复治疗。此外，振动组在每次康复治疗结束时对受伤腿放松的股四头肌施加 1 小时的振动。主要结局——受伤和未受伤腿的最大等长力量（即允许测量肢体不对称）——在 ACLR 前（PRE）和 10 周康复后（POST）进行评估。
结果
7 名参与者失访，因此在完整病例分析中使用了 23 名参与者的数据。对于受伤腿，与对照组（n=11，-16%[10]）相比，振动组从 PRE 到 POST 的最大力量下降幅度明显更低（n=12，-30%[11]；P=0.0045，Cohen's d 效应大小=1.33）。振动组的肢体对称性 PRE-POST 变化平均值低于对照组（-19%[11] vs. -29%[13]），但无显著差异（P=0.051，Cohen's d 效应大小=0.85）。
结论
LVT 改善了 ACLR 后的力量恢复。这项可行性研究表明，应用于放松肌肉的 LVT 是一种很有前途的振动治疗方式，可在 ACLR 早期实施。
