ACL reconstruction surgery leads to temporary limitations in knee movement due to weakness in the quadriceps, swelling, and stiffness. Effective therapy is necessary to regain strength and functionality. While flywheel resistance training enhances strength and eccentric loading, there is limited knowledge about its effectiveness in conjunction with conventional rehabilitation methods. This study evaluates the impact of both conventional rehabilitation and isoinertial therapy on muscle power, endurance, isometric strength, and balance in patients following ACL repair.
A total of 96 out of 136 patients aged 18 to 45 who had been randomly assigned to groups were included 3 weeks post-procedure. Over 6 weeks, 47 patients in group A (n = 47) participated in both isoinertial training and conventional therapy protocals while in group B (n = 49) followed a conventional rehabilitation protocol for just 30 min daily. To assess the patients' muscle power, endurance, isometric strength, and balance, a flywheel ergometer (D11 Plus; Desmotec, Biella, Italy) was utilized both before and after the 6-week treatment period.
Group A had statistically significant increases in eccentric muscular power (p = 0.0001), whereas there was no noticeable difference between the two groups in isometric strength, balance, or concentric power (p = 0.731, p = 0.786, and p = 0.815, respectively).
The finding indicates that isometric strength, balance, and both concentric and eccentric muscular power were successfully improved by both 6-week interventions: traditional rehabilitation alone and in conjunction with isoinertial training. But when compared to traditional therapy alone, the isoinertial training group showed better gains in muscular endurance. There were no discernible variations in the groups' isometric strength or balance results. The study also emphasizes how isoinertial training can effectively increase eccentric power.

由于股四头肌无力、肿胀和僵硬，前交叉韧带重建手术会导致膝关节活动暂时受限。需要有效的治疗来恢复力量和功能。虽然飞轮阻力训练可增强力量和离心负荷，但对于其与传统康复方法结合使用的效果了解有限。本研究评估了传统康复和等惯性疗法对前交叉韧带修复术后患者肌肉力量、耐力、等长肌力和平衡能力的影响。
在术后3周，从136名年龄在18至45岁之间且已被随机分组的患者中，共纳入96名。在6周的时间里，A组（n = 47）的47名患者既参加了等惯性训练，也参与了传统治疗方案，而B组（n = 49）仅每天遵循30分钟的传统康复方案。为评估患者的肌肉力量、耐力、等长肌力和平衡能力，在为期6周的治疗期前后均使用了飞轮测力计（D11 Plus；Desmotec，比耶拉，意大利）。
A组的离心肌肉力量有统计学意义的显著增加（p = 0.0001），而两组在等长肌力、平衡能力或向心力量方面没有明显差异（分别为p = 0.731、p = 0.786和p = 0.815）。
研究结果表明，为期6周的两种干预措施，即单独的传统康复以及与等惯性训练相结合，均成功改善了等长肌力、平衡能力以及向心和离心肌肉力量。但与单独的传统疗法相比，等惯性训练组在肌肉耐力方面有更好的提升。两组的等长肌力或平衡结果没有明显差异。该研究还强调了等惯性训练如何能有效增加离心力量。
