Electromyography (EMG)

A diagnostic test that records the electrical activity of muscles. In the test, small electrodes are placed on or in the skin; the patterns of electrical activity are projected on a screen or over a loudspeaker. This procedure is used to test for muscle disorders, including muscular dystrophy.

As tonic chin EMG activity and AHI showed significant difference between MSA-P group and PD group, both of them had great associations with RBD, so we divided both groups into with (MSA + RBD; PD + RBD) or without RBD (MSA - RBD; PD - RBD) subgroups to make other comparisons.
In order to determine the effect of muscle fatigue on the EMG signal characteristics, the differences in the values of parameters at the end and at the beginning of the tests were analysed.
In patients with normal EMG blink reflex finding, there was 51% probability that the symptoms of headache were present and 49% probability that the symptoms were not present.
came out with a study to evaluate the performance of recursive-least-square adaptive filter in the removal of ECG interference from EMG signal [33].
Experimental design: Surface electrodes were placed on the muscles prior to EMG data capture and the volunteers performed the maximum voluntary isometric contraction test (MVIC) to record the maximum value of the EMG amplitude for data normalization.
While the timing of EMG for these babies remains to be controversial in the literature, a majority of these babies are observed to recover within the first 3 months using conservative methods.
Participants firstly walked on a treadmill (Powerjog JX200, Sport Engineering, UK) at a self-selected pace for two minutes (4 [+ or -] 1 km/hr; mean [+ or -] SD) to warm-up, with EMG signals collected for the entire second minute and used to normalize the data from subsequent exercises.
EMG. Compared with the baseline value, the CIH group begun to show an increased EMG activity of the genioglossus at 10 and 20 min after hypoxia stimulation on the 14th day (71.63 [+ or -] 7.41 versus 82.62 [+ or -] 11.48 and 84 [+ or -] 8.29 for values at baseline, 10 min, and 20 min after IH, resp.; p < 0.05).
To compare EMG activity in the same muscle on different days or different individuals, or to compare EMG activity between muscles, the EMG must be normalized.
