Quantitative analyses of jaw‐opening muscle activity during the active phase of jaw‐closing muscles in sleep bruxism

Abstract

Sleep bruxism (SB) is a repetitive jaw muscle activity characterized by grinding or clenching of the teeth (Lobbezoo et al., 2013) and it is a possible risk factor for various ailments and disorders in the stomatognathic system, such as dislodgement of dental restorations, tooth fracture, tooth wear, periodontal disease and temporomandibular disorder. Studies have been conducted on the relationships of SB genesis with increase in sympathetic nerve activity, sleep state and genetic factors (

Signal acquisition and analysis of ambulatory electromyographic recordings for the assessment of sleep bruxism: A scoping review

“…Pictures of devices were provided in 18 (23%) of the studies. 11,12,14,19,33,37,55,58,59,66,67,83,84,[90][91][92][93][94] Eleven studies used additional instrumental methods to assess sleep bruxism, viz. audio recordings 54 (n = 1), video recordings 95 (n=1), audiovisual recordings 96,97 (n = 2) and electrocardiographic (ECG) activity [82][83][84][85][86][87]92,98 (n = 8, 10%).…”

“…Most studies (n = 44; 57%) utilised a single-channel assembly, 13,14,22,31,37,39,52,54,56,57,[60][61][62][63][64][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81]90,91,[95][96][97][99][100][101][102][103][104][105][106][107] and two and three channels were utilised in 13 (17%) 11,12,32,33,52,59,[92]…”

“…76 Thirty-two studies (41%) 30,32,57,61,62,67,72,77-81,83,85-87,89-91,95-99,103,104,106,108,111,11 2,115,118 did not describe whether participants were given instructions on device handling, while for five studies 33,54,100,101,110 this information was not applicable, since the devices were mounted by the study investigators. As for set-up procedures, for example performing an MVC at the start of the recording, these were described for 37 (47%) of the studies, 11,14,22,30,31,37,39,[52][53][54]56,61,62,[67][68][69]73,77,78,[80][81][82][83][84]90,91,95,96,98,100,101,[107][108][109][110][111]117 while the remaining 41 (53%) studies did not describe such procedures.…”

“…The amplification factor of the signal during acquisition was described in only 19 (24%) studies 14,19,22,30,31,33,[59][60][61]70,83,84,90,91,106,108,110,120 (Table 4). Different amplification factors were used for different devices, ranging from 250 90,115 to 50 000 times. 93 Reports on impedance conditions were scarcer (Table 4).…”

A Novel Hybrid Machine Learning Classification for the Detection of Bruxism Patients Using Physiological Signals

“…They evaluated the masseter muscle activity of the body. Maeda et al [27] studied the validity of the detection of bruxism using EMG and a cut-off rate with optimum sympathy and specificity. A total number of 16 subjects were used in this work.…”
