我们比较了在完整ACL（INT）和重建ACL（REC）的男性和女性受试者执行跳切任务时，股四头肌、腘绳肌和腓肠肌的肌肉活动。表面肌电传感器用于评估肌肉活动峰值时间和肌肉活动比。ACL（INT）组股骨直肌（RF）和股内侧肌（VM）峰值时间分别比ACL（REC）组早71和78ms。ACL（INT）组比ACL（REC）组股骨二头肌（BF）峰值时间早90ms，女性比男性早75ms。前交叉韧带（INT）组腓肠肌内侧肌峰值时间比前交叉韧带（REC）组早77ms。女性腓肠肌（LG）和MG肌的峰值时间分别比男性早106ms和87ms。ACL（REC）组RF、VM、BF和MG峰值晚于ACL（INT）组。有证据表明，前交叉韧带（ACL） （REC）的负荷期股四头肌：腘绳肌（quad:ham）肌肉活动比前交叉韧带（ACL） （INT）的大。最后，损伤风险阶段四：大腿肌肉活动比女性是男性的4.8倍。总之，与前交叉韧带状态和性别相关的肌肉活动存在差异，这可能有助于解释移植物衰竭风险和性别偏见。(c) 2013年骨科研究会。Wiley期刊公司出版。Wiley期刊公司出版。[J]中华骨科杂志，2013
We compared muscle activity of the quadriceps, hamstring, and gastrocnemius muscles when ACL-intact (ACL(INT)) and ACL-reconstructed (ACL(REC)) male and female subjects performed a jump-cut task. Surface electromyography sensors were used to evaluate time to peak muscle activity and muscle activity ratios. Rectus femoris (RF) and vastus medialis (VM) peak timing was 71 and 78ms earlier in ACL(INT) than in ACL(REC) subjects, respectively. Biceps femoris (BF) peak timing was 90ms earlier in ACL(INT) than in ACL(REC) subjects and 75ms earlier in females than in males. Medial gastrocnemius (MG) muscle peak timing was 77ms earlier in ACL(INT) than in ACL(REC) subjects. Lateral gastrocnemius (LG) and MG muscle peak times were 106ms and 87ms earlier in females than in males, respectively. The RF, VM, BF, and MG peaked later in ACL(REC) than in ACL(INT) subjects. There was evidence suggesting that the loading phase quadriceps:hamstring (quad:ham) muscle activity ratio was greater in ACL(REC) than in ACL(INT) subjects. Finally, the injury risk phase quad:ham muscle activity ratio was 4.8 times greater in females than in males. In conclusion, differences exist in muscle activity related to ACL status and sex that could potentially help explain graft failure risk and the sex bias. (c) 2013 Orthopaedic Research Society.
