目的：探讨六周的力量和本体感觉训练对单侧功能性踝关节不稳患者内翻等速力量比（E/I比率）的影响。方法：38名受试者随机分为4组：力量训练组(S)；本体感觉训练；力量+本体感觉训练(B)；控制(C)。使用Kin Com 125自动定位等速测功机测试训练前后的等速力量。距下关节外翻和内翻运动通过40度范围内的同心和偏心运动进行测试。所有峰值扭矩和平均扭矩值均按体重归一化。利用平均转矩和峰值转矩测量值，取同心转矩值与偏心转矩反演值相结合，计算出E/I比。数据分析使用混合模型方差分析与重复测量的测试因素。分别分析了30度/秒和120度/秒时的平均扭矩和峰值扭矩E/I比。结果：训练后各组功能性不稳定踝关节的平均扭矩和峰值扭矩E/I比与训练前比较均无显著差异。结论：六周的力量和本体感觉训练（单独或联合）对自我报告单侧功能不稳定的受试者的力量等速测量没有影响。需要进一步研究这种激动剂（同心）与拮抗剂（偏心）肌群力量比。
Objectives: To examine the effect of six weeks of strength and proprioception training on eversion to inversion isokinetic strength ratios (E/I ratios) in subjects with unilateral functional ankle instability.Methods: Thirty eight subjects were randomly assigned to one of four treatment groups: strength training (S); proprioception training (P); strength + proprioception training (B); control (C). Isokinetic strength was tested before and after training using a Kin Com 125 automatic positioning isokinetic dynamometer. Subtalar joint eversion and inversion motions were tested both concentrically and eccentrically through a range of motion involving 40degrees. All peak torque and average torque values were normalised for body mass. E/I ratios were calculated from average torque and peak torque measures by taking the concentric eversion value and combining it with the eccentric inversion value. Data were analysed using a mixed model analysis of variance with repeated measures on the test factor. Average torque and peak torque E/I ratios at 30 and 120degrees/s were analysed separately.Results: There were no significant differences in average torque and peak torque E/I ratios of the functionally unstable ankle for any of the groups after training compared with before.Conclusions: Six weeks of strength and proprioception training (either alone or combined) had no effect on isokinetic measures of strength in subjects with self reported unilateral functional instability. Further studies examining this agonist (concentric) to antagonist (eccentric) muscle group strength ratio are needed.
