The aim of this study was to investigate the effects of a combined eccentric-concentric exercise program of the ankle evertors and dorsiflexors on proprioception in functionally unstable ankles.
Thirteen male recreational athletes with unilateral functional ankle instability were admitted to this study. The unaffected opposite ankles were used as controls. The functionnaly unstable ankle of the subjects performed an isokinetic exercise program of the ankle evertors and dorsiflexors in a combined eccentric-concentric mode for 3 days per week for 6 wks. Before and after the isokinetic exercise program, active and passive joint position sense and kinesthesia and isokinetic strength of the ankle joint were evaluated.
Active and passive joint position sense error scores for inversion (P < 0.01-0.001) and plantarflexion (P < 0.05-0.001) direction and kinesthesia scores for inversion (P < 0.001) and plantarlexion (P < 0.01) direction showed significant reductions after 6 wks of intervention in the functionnaly unstable ankle. In addition, eccentric peak torques for the ankle evertor and dorsiflexors represented significant (P < 0.001) increases in the functionnaly unstable ankle compared with the control ankle.
The results of this study suggest that it is possible to improve proprioceptive acuity of the ankle joint after a 6-wk eccentric-concentric isokinetic training program in functionally unstable ankles.
本研究旨在探讨踝关节外翻肌和背屈肌的离心-向心联合训练计划对功能不稳定踝关节本体感觉的影响。
13名单侧功能性踝关节不稳定的男性休闲运动员参与了本研究。将未受影响的对侧踝关节作为对照。受试者功能不稳定的踝关节以离心-向心联合模式进行踝关节外翻肌和背屈肌的等速训练计划，每周3天，共6周。在等速训练计划前后，评估踝关节的主动和被动关节位置觉、运动觉以及等速力量。
在功能不稳定的踝关节进行6周干预后，内翻（P < 0.01 - 0.001）和跖屈（P < 0.05 - 0.001）方向的主动和被动关节位置觉误差评分以及内翻（P < 0.001）和跖屈（P < 0.01）方向的运动觉评分均显著降低。此外，与对照踝关节相比，功能不稳定踝关节的外翻肌和背屈肌的离心峰值扭矩显著增加（P < 0.001）。
本研究结果表明，在功能不稳定的踝关节进行6周的离心-向心等速训练计划后，有可能提高踝关节的本体感觉敏锐度。
