We introduce a new method of analysis of the normal and abnormal behavior of the TMJ, using a duplex-doppler spectral analysis. The method consists in monitoring the joint movement by means of a study of the Fourier transformed signals, which give information on the velocity distribution of the condylo-meniscal complex during the opening and closing phases of the jaw. Using repeated sampling over short time intervals we get a detailed description of the motion which allows to discriminate the normal and abnormal action of the condylomeniscal complex. We are able to identify various physiopathological conditions, among which opening and/or closing clicks, complex locking conditions and anomalies related to an asymmetrical behavior during the operation cycle. Duplex-doppler spectral analysis is correlated to a clinical examination in order to define various classes of anomalies.
我们介绍一种分析颞下颌关节正常和异常行为的新方法，即使用双多普勒频谱分析。该方法包括通过研究傅里叶变换信号来监测关节运动，这些信号能提供有关髁突-半月板复合体在开闭口阶段速度分布的信息。通过在短时间间隔内进行重复采样，我们可以得到该运动的详细描述，从而能够区分髁突-半月板复合体的正常和异常动作。我们能够识别各种生理病理状况，其中包括开闭口弹响、复杂的锁定情况以及与操作周期中不对称行为相关的异常。双多普勒频谱分析与临床检查相关联，以定义各种异常类别。
