Lower joint arthrography and videofluoroscopy were used to diagnose 297 joints from temporomandibular disorders (TMD) patients. The surface vibrations of the temporomandibular joints (TMJs) were recorded by electrovibratography and a parameter set was derived through frequency analysis. Total vibration energies were used as the primary separating threshold for abnormal joints. The following conditions were statistically discriminated by multi-variate analyses: I) meniscal displacement with reduction; II) meniscal displacement with a partial disk reduction; III) meniscal displacement without reduction; and IV) degenerative joint disease and/or perforation of the disk. Using the total vibration energy as a threshold, the diagnostic sensitivity for the abnormal joints was 82%, while the diagnostic specificity for the joints with no evidence of internal derangement was 75%. Discriminant analysis for the above-mentioned four conditions revealed a diagnostic sensitivity of 79.0%, 85.7%, 77.1% and 76.3% for conditions I, II, III and IV, respectively. The diagnostic specificity was 76.2%, 79.9%, 59.0% and 77.9% for conditions I, II, III and IV, respectively. It was concluded that vibration analysis of the TMJ could be clinically useful as a screening examination for TMD patients.
采用下颌关节造影和视频荧光透视检查对297例颞下颌关节紊乱病（TMD）患者的关节进行诊断。通过电振动图记录颞下颌关节（TMJ）的表面振动，并通过频率分析得出一组参数。总振动能量被用作异常关节的主要区分阈值。通过多变量分析对以下情况进行了统计学区分：I）可复性盘移位；II）部分盘可复性移位；III）不可复性盘移位；IV）关节退行性疾病和/或盘穿孔。以总振动能量为阈值，异常关节的诊断敏感性为82%，而无关节内紊乱证据的关节的诊断特异性为75%。对上述四种情况的判别分析显示，情况I、II、III和IV的诊断敏感性分别为79.0%、85.7%、77.1%和76.3%。情况I、II、III和IV的诊断特异性分别为76.2%、79.9%、59.0%和77.9%。得出的结论是，TMJ的振动分析作为TMD患者的筛查检查在临床上可能有用。
