Limited ankle dorsiflexion range of motion is one of the most important risk factors for lower limb injury, which changes the biomechanics and the neuromuscular control of the lower limb muscles. This study aims to test the effectiveness of a comprehensive corrective exercise program (CCEP) on the range of motion, proprioception, dynamic balance, and muscle activation in female athletes with limited weight-bearing lunge ankle dorsiflexion range of motion. 30 female athletes aged 15 to 25 years with dorsiflexion under 34° were randomized to two groups. The intervention group (n = 15) received eight weeks of CCEP including soft tissue mobilization, joint mobilization, stretching, and strengthening, and the control (n = 15) group did not receive any intervention. range of motion, proprioception, dynamic balance, and muscle activation were assessed before and after the intervention. The training group showed clinically acceptable and statistically significant changes in ankle dorsiflexion range of motion (ES = 0.714), balance (ES = 0.423), and proprioception (ES = 0.253; P < 0.05). There were significant changes in the activity of the tibialis anterior and soleus muscles in the dynamic overhead squat test (descending and ascending phases) and the activity of the medial gastrocnemius in the descending phase decreased significantly (P < 0.05). No significant change was observed in the activity of the peroneus longus muscle (P > 0.05). The findings show that CCEP appears to be beneficial in increasing dorsiflexion range of motion, proprioception, balance, and decreasing ankle muscle activity among individuals with limited ankle dorsiflexion. Improving the dorsiflexion range of motion may be promising for reducing ankle sprain injury.
踝关节背屈活动度有限是下肢损伤的最重要危险因素之一,它改变了下肢肌肉的生物力学和神经肌肉控制。本研究旨在测试综合矫正运动方案(CCEP)对有承重受限的前足背屈踝关节背屈活动度的女性运动员的活动度、本体感觉、动态平衡和肌肉激活的有效性。30 名年龄在 15 至 25 岁之间、背屈小于 34°的女性运动员被随机分为两组。干预组(n = 15)接受了 8 周的 CCEP,包括软组织松解、关节松动、伸展和强化,对照组(n = 15)未接受任何干预。在干预前后评估了活动度、本体感觉、动态平衡和肌肉激活。训练组在踝关节背屈活动度(ES = 0.714)、平衡(ES = 0.423)和本体感觉(ES = 0.253;P < 0.05)方面显示出临床可接受和统计学上显著的变化。在动态过头深蹲测试中,胫骨前肌和比目鱼肌的活性在下降和上升阶段都有显著变化(下降和上升阶段),内侧腓肠肌在下降阶段的活性显著下降(P < 0.05)。腓骨长肌的活性没有明显变化(P > 0.05)。研究结果表明,CCEP 似乎有利于增加背屈活动度、本体感觉、平衡和降低踝关节肌肉活动度,对背屈活动度有限的个体有益。改善背屈活动度可能对减少踝关节扭伤损伤有希望。
