CV
Riccardo Rosati, CDT, received his DDS degree and PhD at the Università degli Studi di Milano, Italy. In 2011 he obtained a postgraduate degree in“ Endodontology and Restaurative Dentistry” at Università degli Studi di Siena. He is involved in facial morphology and masticatory muscles function research. All investigations were developed using non-invasive instruments allowing healthy subjects measurements to obtain morphofunctional reference values. He is currently is a staff member researcher of the Functional Anatomy Research Center( FARC) of the Università degli Studi di Milano. He works as dentist in Milano and Udine focused on prosthetic reconstructions.
Questions
Which factors could influence the surface electromyographic signal?
qa. the thickness of the hypodermis; qb. the instrumental noise; qc. the position of the electrodes relative to the muscle fibres; qd. all the previous factors.
The Percentage Overlapping Coefficient:
qa. it measures the muscle force; qb. it quantifies the symmetry of muscles contraction; qc. it could be greater than 100 %; qd. it is always lower than 50 %.
The Surface electromyography:
qa. it uses needle electrodes inserted into muscle belly; qb. it is performed applying electrodes on cutaneous surface; qc. it is painful; qd. it is invasive.
The Raw electromyographic signal, standardized on clenching with cotton rolls, allows:
qa. the muscle pain measurement; qb. the dental proprioception related muscle reaction measurement; qc. the muscle force evaluation; qd. the TMJ position analysis.
