To determine whether a neuromuscular rehabilitation program can improve postural stability and ankle-evertor strength and to examine the temporal changes and persistence of the rehabilitation effects in athletes with chronic ankle instability (CAI).
A total of 21 national women field hockey players participated in this study (CAI, n = 12; control, n = 9).
Isokinetic ankle-evertor strength (peak torque [PT], total work [TW]) at 30°/s, 60°/s, 90°/s, and 120°/s, mediolateral stability index (MSI), and dynamic stability test (TCT). Data were recorded at baseline, 6 wk, and 24 wk.
At baseline, isokinetic evertor strength was comparable between groups. At 6 wk, the CAI group demonstrated significantly increased eccentric PT and TW at 30°/s and 60°/s and increased concentric/eccentric TW at 90°/s. The control group showed significantly increased concentric TW at 30°/s and increased concentric PT and TW at 90°/s. At 24 wk, except for eccentric PT at 60°/s and 120°/s, concentric/eccentric PT and TW were significantly increased in the CAI group. The control group showed significantly increased TW at all angular velocities regardless of contraction mode. The CAI group exhibited significant increases in concentric/eccentric evertor PT and TW at 120°/s in comparison with the control group. MSI and TCT decreased in both groups at 6 wk; however, the CAI group demonstrated significant increases in both measures at 24 wk, whereas the control group showed no significant change.
The results suggest that the neuromuscular rehabilitation program had an immediate effect on gaining eccentric evertor strength and improving postural control and appeared to contribute to enhancing the evertor strength of unstable ankles in the longer term. On the other hand, improved postural stability did not seem to persist.
确定神经肌肉康复计划是否能改善姿势稳定性和踝关节外翻肌力量,并研究慢性踝关节不稳(CAI)运动员康复效果的时间变化及持续性。
共有21名国家女子曲棍球运动员参与本研究(CAI组,n = 12;对照组,n = 9)。
30°/秒、60°/秒、90°/秒和120°/秒时的等速踝关节外翻肌力量(峰值扭矩[PT]、总功[TW])、内外侧稳定性指数(MSI)和动态稳定性测试(TCT)。在基线、6周和24周时记录数据。
在基线时,两组之间的等速外翻肌力量相当。在6周时,CAI组在30°/秒和60°/秒时的离心PT和TW显著增加,在90°/秒时的向心/离心TW增加。对照组在30°/秒时的向心TW显著增加,在90°/秒时的向心PT和TW增加。在24周时,CAI组除了60°/秒和120°/秒时的离心PT外,向心/离心PT和TW均显著增加。对照组在所有角速度下,无论收缩模式如何,TW均显著增加。与对照组相比,CAI组在120°/秒时向心/离心外翻肌PT和TW显著增加。两组在6周时MSI和TCT均下降;然而,CAI组在第24周时这两项指标均显著增加,而对照组无显著变化。
结果表明,神经肌肉康复计划对增加离心外翻肌力量和改善姿势控制有即时效果,并且似乎有助于从长期来看增强不稳定踝关节的外翻肌力量。另一方面,姿势稳定性的改善似乎没有持续。
