用一种新设计的仪器使中指近端指间关节快速被动屈曲，在头皮上诱发电位。本研究仔细排除了本体感觉以外的感觉方式的可能贡献。皮层反应的初始部分是对侧中央区的正偏转（刺激后34.6ms的P1）。随后是中额叶负波（N1，44.8 ms）和对侧中央顶叶区的明确阳性（P2，48.0 ms）。尽管缺血性麻醉导致手指皮肤和关节传入纤维的消失，但诱发反应仍持续存在，但前臂缺血性麻醉则使其消失。因此，在这项研究中获得的皮层诱发反应最有可能反映肌肉传入输入。P1的头皮分布提示其皮层发生源不同于正中神经电刺激诱发电位的N20-P20成分。人脑的Brodmann 2区和3a区是本体感受相关诱发反应早期成分最可能的发生部位，它们接受深部感受器输入。P2波幅与运动速度有关，与运动幅度无关。总之，本研究建立了一种方法来记录诱发反应的手指关节的轻快被动运动，这主要反映了通过肌肉传入介导的本体感觉的动态方面。
Brisk passive flexion of the proximal interphalangeal joint of the middle finger, produced by using a newly devised instrument, elicited evoked potentials on the scalp. The present study carefully excluded the possible contribution of sensory modalities other than proprioception. The initial part of cortical response was a positive deflexion at the contralateral central area (P1 at 34.6 ms after the stimulus). This was followed by a midfrontal negative wave (N1 at 44.8 ms) and a clear positivity at the contralateral centroparietal area (P2 at 48.0 ms). The evoked responses persisted in spite of the abolition of cutaneous and joint afferents of the finger caused by ischemic anesthesia, but they were lost by ischemic anesthesia of the forearm. Thus, the cortical evoked responses obtained in this study most probably reflect muscle afferent inputs. The scalp distribution of P1 suggested that its cortical generator source was different from that of the N20-P20 components of evoked potentials to electrical median nerve stimulation. Brodmann areas 2 and 3a of human brain, which are known to receive deep receptor inputs, are the most plausible generator sites for the early components of the proprioception-related evoked responses. The amplitude of P2 was related to the velocity but not to the magnitude of movement. In conclusion, the present study established a method for recording the evoked responses to the brisk passive movement of the finger joint, which mainly reflect the dynamic aspects of proprioception mediated through muscle afferent.
