The relative contributions of intramuscular and extramuscular receptors to changes in the reflex excitability of soleus motoneurons, following muscle stretch, have been studied in man. It was found that reflex excitability was decreased by muscle stretch. The extent of the decrease was related to the amount of stretch, irrespective of whether the latter was produced by dorsiflexion of the ankle or by depression of the Achilles tendon with the ankle joint fixed. The results were unaffected by anaesthesia of the skin. It would appear that neither joint receptors nor cutaneous mechanoreceptors contribute significantly to the decrease in reflex excitability during ankle dorsiflexion and that the intramuscular receptors are mainly responsible for the effects observed.
在人体中，研究了肌肉伸展后，肌内和肌外感受器对比目鱼肌运动神经元反射兴奋性变化的相对贡献。结果发现，肌肉伸展可降低反射兴奋性。降低的程度与伸展量有关，无论伸展是由踝关节背屈还是在踝关节固定时跟腱下压引起的。皮肤麻醉对结果无影响。似乎在踝关节背屈过程中，关节感受器和皮肤机械感受器均未对反射兴奋性的降低产生显著作用，观察到的效应主要由肌内感受器引起。
