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 .
