DEVICE FOR SURFACE RECORDING OF MASSETER MUSCLES

摘要

The present invention relates to a device for surface recording of the masseter muscles comprising: a 2-channel electromyograph machine; a first set of three surface electrodes and a second set of three surface electrodes, wherein with the aid of a head support the first set of surface electrodes is placed on the right side of the head of a subject under study, while the second set of surface electrodes is placed on the left side, both sets or electrodes are disposed at the level of the masseter muscles of the subject under study, whereby the EMG surface activity generated during a test conducted on the subject under study is registered through both sets of surface electrodes and an EMG signal is sent to the electromyograph machine through a first and a second channel for processing and subsequent transfer to a personal computer that allows the analysis of the processed data; and a power supply that provides the power necessary for the proper and optimum device performance.
