在未麻醉的去脑脊髓猫和狗中研究了机械感受器在前交叉韧带（ACL）中的生理作用。四头肌和腘绳肌的紧张性活动增加，以响应ACL的生理负荷。通过电刺激韧带表面，诱发后关节神经（PAN）的诱发电位。ACL负荷也引起了PAN的显著放电。结果表明，ACL负载有一个兴奋性的影响，通过大腿肌肉的多运动神经元输出，PAN是从ACL的机械感受器的传入路线之一。因此，ACL肌肉反射可能在维持膝关节运动学方面发挥生理作用。
The physiological role of mechanoreceptors in the anterior cruciate ligament (ACL) was studied in unanaesthetised decerebrate-spinalised cats and dogs. Tonic activity in the quadriceps and the hamstring increased in response to physiological loading of the ACL. Evoked potentials in the posterior articular nerve (PAN) were elicited by electrical stimulation of the surface of the ligament. ACL loading also induced significant discharges from the PAN. The results suggest that ACL loading has an excitatory effect on the thigh muscles through a multimotor neurone output, and that the PAN is one of the afferent routes from the mechanoreceptors of the ACL. The ACL-muscle reflex may therefore play a physiological role in maintaining knee kinematics.
