压力中心（COP）是踝关节外侧扭伤（LAS）时的突然位移。研究表明，足底压力分布和COP位移量是评估LAS风险的重要指标。因此，我们在闭眼单腿平衡测试（SLB-C）中评估足底压力，以确定反复发生LAS患者足底压力的因素和特征。我们招募了22名大学生运动员，将他们分为不稳定组（IG, n=11）和对照组（CG, n=11）。我们测量了SLB-C期间足底压力和下肢肌肉活动的分布，以及静态对齐和等距踝关节力量。大鼠腓骨长肌（FL）活性明显低于大鼠。IG组的外侧足底压力(LPP)/内侧足底压力（MPP）比也高于CG组。此外，LPP/MPP比值与胫骨前肌(TA)/FL比值相关。这些结果表明，外侧足底压力的增加与FL活性的降低和TA/FL比值的增加有关。
Center of pressure (COP) is a sudden displacement at the time of a lateral ankle sprain (LAS). It has been suggested that the distribution of plantar pressure and the quantity of COP displacement are important for assessing the risk of LAS. Therefore, we evaluated the plantar pressure during a single-leg balance test with eyes closed (SLB-C) to identify the factors and characteristics of plantar pressure in people with repeated cases of LAS. We recruited 22 collegiate athletes and divided them into an instability group (IG; n=11) and a control group (CG; n=11). We measured the distribution of plantar pressure and lower extremity muscle activity during a SLB-C along with static alignment and isometric ankle strength. The fibularis longus (FL) activity was significantly lower in the IG than in the CG. The lateral plantar pressure (LPP)/medial plantar pressure (MPP) ratio was also higher in the IG than in the CG. In addition, the LPP/MPP ratio was correlated with the tibialis anterior (TA)/FL ratio. These results suggest that increased lateral plantar pressure is related to decreased FL activity and increased TA/FL ratio.
