INTRODUCTION There are numerous studies that support the physiological basis for using quantitative electromyography in the diagnosis of temporomandibular disorders (Moyers, 1949; Perry, 1954; Jarabak, 1956; Perry, 1957; Porritt, 1960; Grossman, 1961; Moller, 1966; Yemm, 1976; Bakke et al., 1980; Riise et al., 1982; Sheikholeslam et al., 1983; Riise et al., 1984; Kydd et al.

INTRODUCTION T.E.N.S. modalities are designated into three distinct categories based on technical parameters and physiologic action. (Mannheimer, J. Clinical Transcutaneous Electrical Nerve Stimulation. F.A. Davis, Philad., 1986). A T.E.N.S. mode that uses high rate (50 to 100 Hz), asymmetrical biphasic wave (40-75 usec) is referred to as Conventional. High Frequency T.E.N.S. This mode is designed […]
INTRODUCTION Progress in the field of mandibular tracking was limited by the capability of available instrumentation. As early as 1931 Hildebrand used cinematography of a moving reflective point to track mandibular movement (1). Cineflourography was used by Klatsky in 1941 (2) and was followed by Kurth‟s use of stroboscopic photography in 1942 (3). Mechanical tracking […]
INTRODUCTION The use of the Myo-monitor in clinical dentistry dates from 1969, the mandibular kinesiograph from 1975, and the clinical EMG-1 from 1980. The scientific literature documenting the rationale for use of these modalities has been outlined previously in this report. Additionally, clinical modalities that have been in use successfully for many years develop a […]
SCIENTIFIC STUDIES SUPPORTING SAFETY AND THE EFFICACY OF SURFACE ELECTROMYOGRAPHY IN DENTISTRY INTRODUCTION TO SURFACE ELECTROMYOGRAPHY FOR MUSCLE MONITORING OF MASTICATORY MUSCLES EMG AND ACTION POTENTIALS The conductive properties of the whole nerve and muscle allow measurement of electrical activity with extra-cellular (surface) electrodes. Typical monitoring sites for masticatory muscles include the masseter, anterior temporalis, […]
