The aims of this study were: (i) to monitor changes in central facial paresis in patients with stroke after orofacial therapy, using functional scales and video analysis of the face; and (ii) to investigate correlations between changes in facial movement and mental function of patients after stroke.
A prospective blind randomized study of patients after stroke with facial paresis. The functional status of the experimental group of 50 cases treated with regulation orofacial therapy was compared with 49 control cases after 4 weeks of rehabilitation.
There were changes in facial movement, evaluated with the House-Brackmann Grading System (HBDS), clinical range and two-dimensional video analysis of the distance between the paretic corner of the mouth and earlobe at rest and during smiling, were measured. Facial movement was found to be significantly better in the experimental group after orofacial therapy compared with the control group. Changes in mental status (depression observed using the Beck Depression Inventory (BDI-II) were significantly greater in the experimental group. There was a close correlation between the changes in facial movement and mental status according to Spearman's correlation coefficient.
Orofacial therapy has a significant effect after 4 weeks of treatment on facial movement and mental state in patients with stroke. Based on the results in our study we can say that the improvements are a significantly better in the experimental group (Difference value) in the parameters HBGS, distance between the corner of the mouth and earlobe and BDI-II.
本研究旨在：（i）通过功能量表和面部视频分析监测中风后口面治疗患者的中枢性面瘫变化；（ii）研究中风后患者面部运动变化与精神功能之间的相关性。
对 50 例中风后伴面瘫的患者进行前瞻性盲随机研究。实验组 50 例接受口面治疗调节，与 49 例康复 4 周后的对照组进行比较。
采用 House-Brackmann 分级系统（HBDS）评估面部运动变化，测量临床范围和口角与耳垂在休息和微笑时的二维视频分析距离。与对照组相比，口面治疗后实验组的面部运动明显改善。实验组的精神状态变化（使用贝克抑郁量表（BDI-II）观察到的抑郁）明显更大。根据 Spearman 相关系数，面部运动的变化与精神状态之间存在密切相关性。
口面治疗在中风患者治疗 4 周后对面部运动和精神状态有显著影响。基于我们的研究结果，我们可以说实验组在 HBGS、口角与耳垂距离和 BDI-II 等参数上的改善明显更好（差值）。
