Abstract

Thirteen MMA athletes were fitted with the MiG2.0 Stanford instrumented mouthguard. 451 video confirmed impacts were recoded during sparring sessions and competitive events. The competitive events resulted in five concussions. The impact with the highest angular acceleration from each event was simulated using the GHBMC head model. Average strain in the corpus callosum of concussed fighters was 0.27, which was 87.9% higher than uninjured fighters and was the best strain indicator of concussion. The best overall predictor of concussion found in this study was shear stress in the corpus callosum which differed by 111.4% between concussed and uninjured athletes.

混合武术头部冲击的有限元模拟

摘要

13位MMA运动员配备了斯坦福大学装备的MiG2.0护​​齿器。在对打比赛和竞技比赛中,对451个视频确认的影响进行了重新编码。竞争事件导致五次脑震荡。使用GHBMC头部模型模拟了每个事件中具有最高角加速度的冲击。脑震荡战士的call体平均应变为0.27,比未受伤的战士高87.9%,是脑震荡的最佳应变指标。在这项研究中发现的最佳的脑震荡总体预测指标是call体的剪切应力,在脑震荡和未受伤的运动员之间相差111.4%。
