| Summary / Zusammenfassung | Aim of this project is to investigate whether muscle pain of patients with craniomandibular disorders can be at least precipitated by the overloading of masticatory muscles. For this purpose we record and analyze the functional and parafunctional electromyographic (EMG) signals of masticatory muscles. EMG signals are recorded in the natural environment by means of small portable recorders developed at our laboratory or in sleep laboratories by means of polysomnography. For every contraction episode, the computer calculates occurrence time, intensity, duration, and the integral of the EMG signal over time. Data on the nocturnal activity patterns of a normal group in the natural environment have already been published. Data from nocturnal bruxers or patients with craniomandibular disorders are compared to those of a normal population. In this context we are also investigating whether patients with craniomandibular disorders clench more often at daytime than asymptomatic subjects. | ||||
