目的/假设：比较面部联带运动测量的客观、计算机化方法与主观方法的敏感性，并检验这些方法的重测信度。
研究设计：前瞻性、非随机、盲法。
研究方法：远程面部运动在上眼睑和口腔连合在一个闭唇微笑和眼睑关闭测量使用市售的计算机运动分析系统。30名面神经功能正常的健康成年人被纳入研究，以建立正常的数据和联带运动的阈值。根据联带运动阈值对30例连续患者进行分析。由两名观察员对相同患者进行独立的盲态主观评价。
结果如下：面部联带运动的检测显着更频繁的客观比主观分析眼睑关闭，没有显着差异的方法之间显示为闭唇微笑。有趣的是，5例（17%）患者在面神经损伤后3个月内出现早期联带运动。所有客观措施的重测信度是优秀的表达。对于两种表达，两个观察者的测试和重新测试主观评价之间的联带运动患者百分比接近一致。
结论：客观的，计算机化的方法来检测面部联动具有良好的可靠性，是更敏感的主观方法来评估与眼睑闭合相关的面部联动的存在。早期联带运动的发现提示中枢神经重组在面神经再生中起作用。
Objectives/Hypothesis: To compare the sensitivity of an objective, computerized approach to measurement of facial synkinesis with that for a subjective approach and to examine the test-retest reliability of these approaches.
Study Design: Prospective, nonrandomized, and blinded.
Methods: Remote facial motion at the upper eyelids and oral commissures during a closed-lip smile and eyelid closure were measured using a commercially available computerized motion analysis system. Thirty healthy adults with normal facial nerve function were enrolled to establish normative data and a threshold value for synkinesis. Thirty consecutive patients were analyzed based on the synkinesis threshold value. Blinded subjective evaluations by two observers were also performed independently on the same patients.
Results: Facial synkinesis was detected significantly more frequently with objective than subjective analysis for eyelid closure; no significant differences between approaches were shown for the closed-lip smile. Interestingly, five (17%) patients developed early synkinesis within 3 months from the onset of the facial nerve injury. The test-retest reliability of all objective measures was excellent for both expressions. Close agreement in percent of patients with synkinesis between test and retest subjective evaluations was obtained for both observers for both expressions.
Conclusions: The objective, computerized approach to detection of facial synkinesis has excellent reliability and is more sensitive than the subjective approach to assessment to the presence of facial synkinesis associated with eyelid closure. The finding of early synkinesis suggests that central nervous reorganization plays a role in regeneration of the facial nerve.
