Incorporation of physiologic muscle tensions to simulate normal in vivo joint loading in cadaveric biomechanical studies has been a challenging problem, especially about the knee, foot, and shoulder. Simulation of muscle contraction requires attachment of tension producing devices to musculotendinous units. To this end, we modified the 'cryo-jaw' device, first described by Riemersma and Schamhardt (1982, J. Biomechanics 15, 619-620) to couple linear actuators to fresh cadaver tendons. These clamps were used in the simulation of 11 different muscles in laboratory investigations of shoulder, elbow, knee, and foot function. The clamps were able to transmit repetitively 3500 N of quadriceps force in eight knees and 2000 N of Achilles force in 11 feet. Overall success rate was 95%.
在尸体生物力学研究中，纳入生理肌肉张力以模拟正常体内关节负荷一直是一个具有挑战性的问题，尤其是在膝关节、足部和肩部方面。模拟肌肉收缩需要将产生张力的装置连接到肌腱单位。为此，我们对Riemersma和Schamhardt（1982年，《生物力学杂志》15卷，619 - 620页）首次描述的“冷冻夹”装置进行了改进，以便将线性致动器与新鲜尸体肌腱相连。这些夹具用于肩部、肘部、膝盖和足部功能的实验室研究中，模拟11种不同的肌肉。这些夹具能够在八个膝关节中重复传递3500 N的股四头肌力量，在11只足部中传递2000 N的跟腱力量。总体成功率为95%。
