Science of Electromyography (sEMG)

What Is Surface Electromyography (sEMG) — And Why Is It the Gold Standard for Measuring Masticatory Muscle Activity?

Introduction

Surface electromyography (sEMG) measures muscle activity in real time, allowing clinicians to evaluate how the masticatory and cervical muscles function during rest and movement. In neuromuscular dentistry, understanding what surface electromyography measures is essential for interpreting functional balance within the stomatognathic system.

In clinical application, sEMG helps identify patterns of hyperactivity, asymmetry, and abnormal recruitment that are not visible through conventional occlusal analysis. This provides insight into how the neuromuscular system is adapting to occlusion, posture, and mandibular position.

Regulatory Recognition of Surface Electromyography in Dentistry

Surface electromyography has received formal regulatory recognition as a diagnostic aid in the management of temporomandibular disorders. The American Dental Association’s Council on Scientific Affairs awarded surface electromyography (sEMG) its “Seal of Acceptance” as a diagnostic aid in the management of temporomandibular disorders (JADA 1996;127:1615-1616). The Myotronics K7 system, which integrates sEMG with computerized mandibular scanning and electrosonography, received its own ADA Council Acceptance Seals for K7/EMG in October 2001 and for the full K7 system in April 2004.¹ The ADA Seal Program for professional products was subsequently phased out effective April 29, 2007, as an administrative discontinuation of the program rather than a clinical determination about TMD instrumentation. Surface electromyography measurement devices are FDA-cleared under 510(k) for use in the diagnosis and management of TMD.

For the broader regulatory framework and chronological documentation, see our companion pages: Science of K7 Electronic Diagnostic Instrumentation → and Computerized Electro-Diagnostic Instrumentation →.

Etiologic Value of Surface Electromyography

The clinical value of surface electromyography extends beyond confirmation of clinical suspicion. sEMG reveals what conventional examination cannot capture: muscle activity at rest that the patient cannot describe and the examiner cannot palpate with reliability, asymmetries in recruitment that no manual test can quantify, and patterns of chronic compensation that explain why symptoms persist when the dental occlusion appears clinically adequate.

In most TMD patients presenting to general dental practice, the masticatory muscles are not at rest. They are doing chronic, low-grade work to hold the mandible in a position the occlusion has imposed. The patient does not feel this work as effort because adaptation has normalized it. The clinician does not detect it on palpation because the muscles feel firm rather than tender. But the electrical activity is there, measurable in microvolts, and it is what is driving the symptom cascade — the headaches, the bruxing, the facial pain, the postural compensation, the joint loading.

When a GNM orthotic provides the mechanical support the masticatory system has been compensating to find, the resting EMG drops. The chronic work stops. The symptoms attributable to that chronic work resolve. This is the etiologic chain that sEMG measurement makes visible. Conventional examination treats the symptoms because conventional examination cannot see the cause. Surface electromyography sees the cause and allows the cause to be addressed.

What Surface Electromyography Measures

Surface electromyography (sEMG) is a series of tests to more specifically delineate and define hypertonic musculature in the compromised TMJ patient. These series of tests are necessary to differentially diagnose between intra-capsular interference (meniscal or otherwise) and extra-capsular interference (influence of the surrounding hypertonic muscular matrix) so as to determine the predominant dysfunctions. Surface electrodes are placed over the muscles which in turn send impulses to the recording instrument. Defining the etiology of the TMJ patient’s predominate neuromuscular dysfunctions will preclude misdirected palliative treatment regimens.
Surface EMG is not a measure of pain.
Surface electromyography (EMG) utilizes eight channels monitoring the right and left anterior temporalis muscles, right and left masseters, and right and left anterior digastric muscles and right and left cervical group of muscles. A clinical hands-on muscle palpation examination is not able to quantify and objectively record muscle hypertonicity without subjective intervention.
Muscles of the face and jaw can be recorded to determine hyperactive muscle activity and/ or resting muscle activity. A strained jaw position can affect muscle activity. The objective is to determine the optimal resting jaw position at physiologic rest that harmonizes with resting EMG levels.

Surface EMG: A Gold Standard for Monitoring Muscle Activity

Surface electromyography has long been the “gold standard” for monitoring muscle activity of masticatory muscle at REST and in FUNCTION. The value of surface EMG is best expressed by C.J. DeLuca, Professor of Biomedical Engineering and Research and Professor of Neurology at Boston University, “Surface EMG utilizes sensing electrodes placed on the skin, which allows the clinician to directly and accurately monitor muscle activity. This is far more accurate procedure than conventional manual palpation or touch which can provide only gross assessments of muscle activity.” 1988. W.D. McCall also states “… there is general agreement among both clinicians and investigators that masticatory muscle activity is increased in symptomatic patients as compared with normal subjects. Electromyography is the principal tool used to investigate such differences.” (The Musculature. A Textbook of Occlusion, Quintessence, 1988).

Scientific Studies Supporting the Efficacy of sEMG

  • There is a broad body of literature that supports the physiologic basis for using surface EMG as an aid in assessment of muscle function/ dysfunction. (38 + studies support this ending with Lynn et al, 1992).
  • There is substantial evidence based upon controlled studies that confirm that surface EMG is reliable and reproducible. (18 studies ending with Dean et al., 1992).
  • 87 studies verifying the use, safety, and efficacy of EMG to monitor masticatory muscle function/ dysfunction.

“In summary, based on well controlled empirical and clinical studies that have been conducted in several universities over the past three decades throughout the world, there is unequivocal evidence to strongly support the use of EMG for the evaluation and diagnosis of temporomandibular disorders.” – Robert Jankelson, D.D.S.
K7 Instrumentation Studies - GNM
Many investigators have confirmed the safety, efficacy and value of surface electromyography for assessing RESTING and FUNCTIONAL status of muscle. There is a broad body of literature that supports the physiologic basis for using surface EMG as an aid in assessment of muscle function/ dysfunction. (Moyer, 1949; Lippold, 1952; Perry, 1954; Bigland and Lippold, 1954; Jarabak, 1956; Perry, 1957; Porritt, 1960; Grossman, 1961; Moss and Greenfield, 1965; Moller, 1976; Mitani et al., 1972; Moss and Chalmers, 1974; Moller, 1975; Yemm, 1976; Milner-Brown and Stein, 1975; Pruim et al., 1978; Bakke et al., 1980 Riise et al., 1982; Sheikholeslam et al., 1982; Sheikholeslam et al., 1983 Riise et al., 1984; Algren et al., 1985; Kyslinski et al., 1985; Sherman, 1985; Goldensohn, 1986; Hermans et al., 1986; Kydd et al., 1986; Sheikholeslam et al., 1986; Balciunas et al., 1987, Burdette and Gale, 1987; Wood, 1987; Crain and Clemons, 1988; Chong-Shan and Hui-yun, 1989; Christensen, 1989; Koole et al.; Neil etal., 1989; Van Eijen et al., 1990; Jankelson, 1992; Lynn et al, 1992).
The following list below is a partial list of the large body of supportive evidence documenting the use and efficacy of electromyography as applied in clinical dentistry.

Physiologic Basis for Using Quantitative EMG

There are numerous studies that support the physiologic basis for using quantitative electromyography in the diagnosis of temporomandibular and occlusal 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., 1986).

Surface EMG is Reliable and Reproducible

There is evidence, based on controlled studies that used extensive statistical tests, that surface electromyography is reliable and reproducible (Goldensohn, 1966; Lloyd, 1971; Mitani and Yamashita, 1978; Riise, 1983; Hermens et al., 1986; Burdette and Gale, 1987).

Relationship Between EMG and Muscular Force

Controlled studies that used extensive statistical tests show that there is a strong relationship between EMG and muscular force (Lippold, 1952; Bigland et al., 1954; Molin, 1972; Milner-Brown, 1975; Pruim, 1978).

EMG Studies of Postural Rest and Maximal Bite Position

Several studies have quantitatively investigated the EMG during postural activity of the mandible and during maximal bite in the intercuspal position. The EMG values for the temporal and masseteric muscles have been quantitatively investigated in these studies for control subjects without functional disorders and for patients with functional disorders. (Lous et al., 1970; Moller et al., 1971; Sheikholeslam et al., 1980; Sheikholeslam et al., 1982; Moller et al., 1982; Cram and Engstrom, 1986). These studies replicated the results that quantified statistically significant differences between the normal population and the patient population.

EMG Studies of Bite Force in Patients with Functional Disorders

There is evidence based on controlled studies that used extensive statistical test that maximal bite force and the electrical muscle activity during maximal bite in the intercuspal position are significantly weaker in patients with functional disorders of the masticatory system than controls without such disorders (Molin, 1972; Helkimo et al., 1975; Randow et al., 1976; Sheikholeslam et al., 1980; Moller et al., 1982; Sheikholeslam et al., 1982; Kydd et al., 1986.)

EMG Postural Studies of Temporalis and Masseter Muscle Activity

Controlled studies that used extensive statistical tests conclude that postural activity of temporalis and masseter muscles are significantly higher in patients with functional disorders of the masticatory system than controls without such disorders (Moller, 1966; Lous et al., 1970; Moller et al., 1971; Sheikholeslam et al., 1982; Pantaleo et al., 1983; Gervais et al., 1989.)

EMG is Effective in the Diagnosis of Myofascial Pain

Clinical studies investigating electromyography of temporal and masseteric muscles concluded that EMG was effective in the diagnosis of myofascial pain disorders (Sheikholeslam et al., 1986; Pantaleo et al., 1983; Cooper et al., 1986; Moller, 1969; Helkimo et al., 1975; Kyslinski et al., 1985; Riise et al., 1982; Sheikholeslam et al., 1983; Riise et al., 1984). These studies further validate the basis for the use of EMG in clinical dentistry. The patients examined in the above studies exhibited high levels of EMG postural activity and weak EMG activity during maximal bite in the intercuspal position. Occlusal therapy resulted in significant improvement in symptoms and pain, and the successfully treated patients had significantly lower postural activity and significantly improved and symmetrical maximal bite activity.

Frequently Asked Questions

🔹 What does surface electromyography measure that palpation and clinical examination cannot?

Surface electromyography records the electrical activity of masticatory and cervical muscles in microvolts (μV), with measurements that are objective, reproducible, and quantitative. Palpation captures the clinician’s subjective impression of muscle tension at a single moment of clinical contact. sEMG captures continuous data across rest, function, and recovery — and does so without the variability inherent in palpation findings between examiners. Where palpation tells the clinician what the muscle feels like, sEMG tells the clinician what the muscle is doing. Elevated resting EMG signals chronic compensatory muscle activity that the patient cannot describe (because adaptation has normalized it) and the examiner cannot reliably palpate (because the muscles feel firm rather than tender). This is the dimension of clinical reality sEMG makes visible — the chronic neuromuscular work that drives the symptom cascade most TMD patients present with. This is not interpretation. This is measurement.

🔹 Why is sEMG considered the standard for masticatory muscle evaluation?

Because over fifty years of peer-reviewed research has established it as such. The literature spanning Moyer (1949) through Lynn et al. (1992) — more than 87 studies cataloged on this page alone — documents the reliability, reproducibility, and clinical efficacy of surface electromyography in masticatory muscle assessment. The American Dental Association’s Council on Scientific Affairs awarded sEMG its “Seal of Acceptance” as a diagnostic aid in the management of temporomandibular disorders (JADA 1996;127:1615-1616). FDA 510(k) clearance is in place. The research base, regulatory authority, and clinical validation are all established. What is missing in most dental practices is not the recognition that masticatory muscle measurement matters — it is the training to interpret sEMG data clinically and incorporate it into routine TMD workflow. The OC GNM curriculum closes that gap.

🔹 What does sEMG reveal that surface palpation cannot?

Where palpation captures the subjective impression of one moment, sEMG captures objective electrical data across the full duration of function. Palpation finds areas that feel tender to the clinician’s touch; it cannot quantify the level of chronic muscle work being done at rest, the asymmetry between left and right channels, or the difference between voluntary and reflexive activation. sEMG quantifies all three. The eight-channel K7 sEMG monitors left and right anterior temporalis, left and right masseter, left and right cervical group, and left and right anterior digastric muscles simultaneously. The clinician sees the pattern — which muscles are firing, when, and at what intensity — across continuous time. This is the data conventional clinical examination cannot produce, and it is the data the GNM clinician needs to identify the muscular state driving the patient’s presentation.

🔹 How does sEMG verify whether GNM orthotic treatment is actually working?

By recording resting EMG before orthotic delivery and after GNM orthotic adjustment — and comparing the recordings objectively. Pre-treatment Scan 9 typically shows elevated 8-channel resting EMG values reflecting chronic compensatory muscle activity. Post-treatment Scan 9 shows whether those values have moved toward the physiologic 1.5-2.8 μV range. A drop in resting EMG documents that the chronic muscular work has stopped — that the patient’s masticatory system is no longer compensating to hold the mandible in a non-physiologic position. This is not subjective improvement reported by the patient. It is electrical evidence that the underlying mechanical state has changed. Without sEMG, treatment outcomes are reported. With sEMG, they are measured.
