Although strength training is commonly used to rehabilitate ankle injuries, studies investigating the effects of strength training on proprioception have shown conflicting results.
To determine the effects of a 6-week strength-training protocol on force sense and strength development in participants with functional ankle instability.
Randomized controlled clinical trial.
University athletic training research laboratory.
A total of 40 participants with functional ankle instability were recruited. They were randomly placed into a training group (10 men, 10 women: age = 20.9 ± 2.2 years, height = 76.4 ± 16.1 cm, mass = 173.0 ± 7.9 kg) or control group (10 men, 10 women: age = 20.2 ± 2.1 years, height = 78.8 ± 24.5 cm, mass = 173.7 ± 8.2 kg).
INTERVENTION(S): Participants in the training group performed strength exercises with the injured ankle 3 times per week for 6 weeks. The protocol consisted of a combination of rubber exercise bands and the Multiaxial Ankle Exerciser, both clinically accepted strengthening methods for ankle rehabilitation. The progression of this protocol provided increasingly resistive exercise as participants changed either the number of sets or resistance of the Thera-Band or Multiaxial Ankle Exerciser. Main Outcome Measure(s): A load cell was used to measure strength and force sense. Inversion and eversion strength was recorded to the nearest 0.01 N. Force-sense reproduction was measured at 2 loads: 20% and 30% of maximal voluntary isometric contraction.
Increases in inversion (F(1,38) = 11.59, P < 0.01, η(p)(2) = 0.23, power = 0.91) and eversion (F(1,38) = 57.68, P < .01, η(p)(2) = 0.60, power = 0.99) strength were found in the training group at the posttest when compared with the control group. No significant improvements were noted in force-sense reproduction for either group.
Strength training at the ankle increased strength but did not improve force sense.
虽然力量训练常用于踝关节损伤康复，但研究表明，力量训练对本体感觉的影响结果相互矛盾。
确定 6 周力量训练方案对功能性踝关节不稳定参与者的力量感觉和力量发展的影响。
随机对照临床试验。
大学运动训练研究实验室。
共招募 40 名功能性踝关节不稳定患者。他们被随机分为训练组（10 名男性，10 名女性：年龄=20.9±2.2 岁，身高=76.4±16.1cm，体重=173.0±7.9kg）或对照组（10 名男性，10 名女性：年龄=20.2±2.1 岁，身高=78.8±24.5cm，体重=173.7±8.2kg）。
训练组患者每周使用受伤的踝关节进行 3 次力量训练，持续 6 周。该方案由橡胶运动带和多轴踝关节运动器的组合组成，两者都是临床认可的踝关节康复强化方法。随着参与者改变 Thera-Band 或多轴踝关节运动器的组数或阻力，该方案的进展提供了越来越大的阻力练习。主要观察指标：使用测力传感器测量力量和力量感觉。记录内翻和外翻力量，精确到 0.01N。力量感觉再现测量 2 种负荷：最大随意等长收缩的 20%和 30%。
与对照组相比，训练组在测试后内翻（F(1,38)=11.59，P<0.01，η(p)(2)=0.23，功率=0.91）和外翻（F(1,38)=57.68，P<0.01，η(p)(2)=0.60，功率=0.99）力量显著增加。两组的力量感觉再现均无明显改善。
踝关节力量训练增加了力量，但没有改善力量感觉。
