The activity of human spindle afferents from finger extensor muscles has been studied during voluntary position holding at two finger positions, to disclose any explicit monitoring of muscle length. The results indicate that, taken as groups, neither primary nor secondary afferents show explicit position responses during active position tracking. Thus any contribution from muscle spindle to position sense must be derived from other components in spindle afferent discharge.
在两个手指位置进行主动位置保持期间，对来自手指伸肌的人体梭内肌传入纤维的活动进行了研究，以揭示对肌肉长度的任何明确监测。结果表明，总体而言，在主动位置跟踪过程中，初级传入纤维和次级传入纤维均未表现出明确的位置反应。因此，肌梭对位置觉的任何贡献都必须源自梭内肌传入放电的其他成分。
