“…However, such electrophysiological assessment tests are invasive and can cause pain to the patient because the electrode is inserted into the subcutaneous area and only information related to the end of the electrode is detected. In contrast, SEMG is a noninvasive method of attaching electrodes to the surface of the face, which does not cause pain to the patient and can detect all informa-tion of a single exercise unit in the muscle [9]. Moreover, it is significant that it can be used in clinical practice in conjunction with the theory of the Meridian muscle in Korean medicine [10].…”

Background:The aim of this study is to determine the correlation between clinical assessment scales, self-assessment scales, and surface electromyography (SEMG) for facial nerve palsy. Methods: This study assessed 32 cases of facial nerve palsy on the first visit, 11 cases on the second visit, and 9 cases on the third visit to the Korean medicine hospital, university. This study was conducted from October 22, 2022, to December 22, 2022. The patients were evaluated using SEMG, clinical assessment scales, and self-assessment scales 3 times. The House-Brackmann grading systems (HBGS), Yanagihara unweighted grading system (Y-score), facial disability index, numerous rating scale, and accompanying symptoms of facial nerve palsy were used for assessment. Moreover, statistical correlation was analyzed using Pearson correlation. Results: On Visit 1, Significant correlations were observed between the results of SEMG and other clinical assessment scales as well as between SEMG-F (frontalis) and different parts of the Y-score. On Visit 2, significant correlations were observed between the results of SEMG and HBGS as well as between SEMG-F and the detailed parts of the Y-score. On Visit 3, significant correlations were observed only between SEMG-F and the detailed parts of the Y-score. A significant correlation was also observed between the changes in the clinical assessment scales on Visits 1 and 3 and between the changes in SEMG-F and those in the patient self-assessment scales. Conclusion: These findings suggest that SEMG can be used to evaluate facial nerve palsy in conjunction with the use of other clinical assessment scales.
