Surface EMG reliability using spectral analysis

Journal of Oral Rehabilitation
J BuxbaumF R Parente

Abstract

Several papers have recently appeared in the literature questioning the usefulness of surface EMG in the management of temporomandibular dysfunction (TMD) patients. One of the concerns is the stability of EMG over time in any one patient. This study was undertaken on normal subjects to determine the level of surface EMG stability over time using a variety of spectral analysis parameters. Four male and seven female subjects, ranging from 24 to 38 years of age, were selected for the study. All subjects had class I occlusions, intact dentition and no history of TMD. Oral and perioral hard and soft tissues were within normal limits. EMG data from the bilateral masseter muscles were obtained during four states of jaw activity: rest, right-sided chewing, left-sided chewing, and 50% maximal clench. Three sets of recordings were obtained in each study session. Three 10-min study sessions were obtained for each subject. Six measures, which included SP-50, central frequency, band width, effective band width, zero crossings and power spectrum, were analysed to assess their reliability and sensitivity over time during the several states of jaw activity. The conclusion of the study was that bilateral masseter EMG band width, effective band ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
