Relation between facial morphology on lateral skull radiographs and sEMG activity of head, neck, and trunk muscles in Caucasian adult females

Surface electromyographic assessment of patients with long lasting temporomandibular joint disorder pain

“…EMG potentials collected in MVC have been reported to have the best repeatability (Forrester et al, 2010;Suvinen et al, 2009). Among the various protocols, an MVC on cotton rolls has been reported to have the lowest inter-individual variability (De Felício et al, 2009;Ferrario et al, 2006;Forrester et al, 2010), and a method based on this standardization has been in use in the last 10 years (Ferrario et al, 2000;Tecco et al, 2011). According to this protocol, normalized EMG data will inform on the influence of occlusion (teeth contact) on the neuromuscular activity, avoiding individual variability (anatomical variations, physiological and psychological status, etc.) and technical variations (muscle cross-talk, electrode position, etc.).…”

sEMG activity of masticatory, neck, and trunk muscles during the treatment of scoliosis with functional braces. A longitudinal controlled study

“…The repeatability of the recording protocol was investigated for the test conditions, by asking the selected subjects to repeat the sEMG recording twice, with a gap of 15 min between the two recordings, as reported in previous researches (intra-operator method error) (Tecco et al, 2008;Tecco et al, 2011;Saccucci et al, 2011). We asked the subjects to stay relaxed during this 15-min break once the electrodes were removed from their muscles, and to walk around the laboratory if they wanted to.…”

“…This was performed in an attempt to reduce the effects of the nonstationary nature of sEMG signals (Christensen and Hutching, 1992;Tecco et al, 2008Tecco et al, , 2011Saccucci et al, 2011;Moorrees, 1994).…”

EMG spectral characteristics of masticatory muscles and upper trapezius during maximum voluntary teeth clenching

“…Current evidence underlines the existence of close interrelationships between the different components of the cranio-cervicalmandibular system, with coordinated activities of the mandibular, neck and trunk muscles (Armijo-Olivo and Magee, 2007;Ceneviz et al, 2006;Ferrario et al, 2003Ferrario et al, , 2006Ferrario et al, , 2007Learreta et al, 2007;Miralles et al, 2002;Pallegama et al, 2004;Tecco et al, 2007Tecco et al, , 2008Tecco et al, , 2011Zuniga et al, 1995). In healthy subjects, a quantitative assessment of these muscles during the performance of physiological jaw and neck movements may offer some knowledge about the normal mechanisms of their integrated action and nervous control (Armijo-Olivo and Magee, 2007;Ceneviz et al, 2006;Ferrario et al, 2003Ferrario et al, , 2006Forrester et al, 2010;Learreta et al, 2007;Miralles et al, 2002;Zuniga et al, 1995).…”
