Objective: To assess the effect of the ethyl chloride spray on motor unit action potential (MUAP) morphology to the needling area who undergoes needle electromyography. Methods: Twenty examinees were enrolled to see the effect of the variability of the motor unit action potentials during needle electromyography (EMG). After needle insertion in biceps brachii muscle, examinees contracted the muscle and quantitative electromyography motor unit action potentials were analyzed. After being analyzed, the ethyl chloride was sprayed over the site of needle insertion and then quantitative electromyography was carried out again. Results: Quantitative electromyography showed that the amplitude and phase were not changed in all examinee after ethyl chloride spraying. However the duration was elongated with significant statistical difference. Conclusions: Our results suggest that ethyl chloride spraying before needle EMG study could change MUAP duration parameters. So, we must consider such changes in analyzing needle EMG result when using ethyl chloride spraying

Objectives : This study was performed in order to investigate the effectiveness of electromyography and the Heart Rate Variability(HRV) test as prognosis factors, and to clarify correlation between Electro- myography and the Heart Rate Variability test. Methods : 44 Bell’s palsy patients who were graded V on the House-Brackmann scale and underwent HRV and EMG testing were retrospectively reviewed based on medical records. Results from both tests were analyzed via simple linear regression, and bivariate correlation analysis was performed to investigate the correlation between results from the two tests. The severity of the facial palsy at onset and at 2 weeks after treatment were evaluated with the H-B grade and Yanagihara grading system, and was converted into improvement scores. Results : Mean axonal loss according to electromyography showed a statistically significant correlation in predicting peripheral facial palsy improvement(p<0.01). HR, SDNN, TP, LF, HF, VLF, and LF/HF ratio on the Heart Rate Variability test showed no significant correlation in predicting peripheral facial palsy improvement. Mean axonal loss determined by electromyography, and HR, SDNN, TP, LF, HF, VLF, and LF/HF ratio recorded with the Heart Rate Variability test was analyzed with the bivariate correlation analysis method. Mean axonal loss and SDNN showed a statistically significant correlation(p<0.01). Conclusions : The Heart Rate Variability test has no statistical significance in predicting peripheral facial palsy improvement. SDNN has a statistically significant correlation with mean axonal loss as deter- mined by electromyography.

전환장애의 기능위약에 대한 새로운 양성징후: 표면근전도를 이용한 수면다원검사

황보진섭,강미리,지기환 대한수면연구학회 2020 Journal of sleep medicine Vol.17 No.2

Patients often present with combinations of psychological disorders that manifest with neurological symptoms and/or signs that are not attributable to identifiable structural or functional etiology associated with the nervous system. We present the case of an elderly woman with functional weakness, which was documented using polysomnography with extended surface electromyography. Our findings show that polysomnography with extended surface electromyography may be a useful diagnostic tool for functional weakness in conversion disorder.

임영관,김재형,김병국 대한안면통증∙구강내과학회 2021 Journal of Oral Medicine and Pain Vol.46 No.4

Purpose: Oromandibular dystonia is a neurological disorder that affects the jaw and lower face muscles, often resulting in abnormal repetitive movement of the jaw and perioral structures. The purpose of this study was to assess the effectiveness of surface electromyography (EMG) in evaluating the treatment outcome of oromandibular dystonia. Methods: Based on a retrospective review of medical records, we analyzed the data of four patients who received medication or botulinum toxin injection, as well as surface EMG of the jaw muscles before and after treatment. We assessed the patients’ clinical characteristics and the results of surface EMG before and after treatment. Results: The case series included one female and three males, and the age range was 65- 78 years. Based on the clinical features, two subjects were classified as jaw deviation and the remaining two were as jaw closing. Dystonic patterns revealed by surface EMG varied, including phasic, tonic, and mixed contraction patterns. EMG amplitude after treatment was lower than pre-treatment value in all four subjects, suggesting improved clinical signs and symptoms. One subject who received clonazepam and another who received botulinum toxin injection showed a remarkable reduction in EMG amplitude within a normal range. Conclusions: Surface EMG can be used to effective evaluate treatment outcomes in patients with oromandibular dystonia. It could be considered as an adjunctive diagnostic tool in managing patients with dystonia.

( Yoseb Lee ),( Yuri Cha ),( Young Kim ),( Sujin Hwang ),( Yijung Chung ) 물리치료재활과학회 2017 Physical therapy rehabilitation science Vol.6 No.3

Objective: The purpose of this study was to explore the effect of repetitive wrist extension task training with electromyography (EMG)-triggered neuromuscular electrical stimulation (NMES) for wrist extensor muscle recovery in patients with stroke. Design: Randomized controlled trial. Methods: Fifteen subjects who had suffered a stroke were randomly assigned to an EMG-triggered NMES group (n=8) or control group (n=7); subjects in both groups received conventional therapy as usual. Subjects in the experimental group received application of EMG-triggered NMES to the wrist extensor muscles for 20 minutes, twice per day, five days per week, for a period of four weeks, and were given a task to make a touch alarm go off by activity involving extension of their wrist. In the control group, subjects performed wrist self-exercises for the same duration and frequency as those in the experimental group. Outcome measures included muscle reaction time and spectrum analysis. Assessments were performed during the pre- and post-treatment periods. Results: In the EMG-triggered NMES group, faster muscle reaction time was observed, and median frequency also showed improvement, from 68.2 to 75.3 Hz, after training (p<0.05). Muscle reaction time was significantly faster, and median frequency was significantly higher in the experimental group than in the experimental group after training. Conclusions: EMG-triggered NMES is beneficial for patients with hemiparetic stroke in recovery of upper extremity function.

Facial Nerve Damage in Bell’s Palsy according to When Korean Medical Treatment was Started : A Retrospective Study Ji Eun Choi1, Min Soo Kwon1, Jung Hwan Kim1, Dae Hyun Jo1, Ji Sun Han1, Hee Jin Jo1, Ji Hye Kim1, Hyun Ho Kim2, Jung Won Kang1 and Dong Woo Nam1,* 1Department of Acupuncture & Moxibustion Medicine, College of Korean Medicine, Kyung Hee University 2Department of Biofunctional Medicine & Diagnostics, College of Korean Medicine, Kyung Hee University Objectives : Although integrative Korean medical treatments have been suggested to be effective for treating Bell’s palsy, the effect of Korean medical treatment according to when treatment was started is unknown in the clinical field. Therefore, this study was conducted to determine the results of treating Bell’s palsy according to different starting points of integrative Korean medical treatments. Methods : We screened patients who visited the Facial Palsy Center at Kyung Hee University Hospital for Korean and Western combined medical treatment from March 2011 to February 2016. A total of 821 out of 2086 patients were studied, including their basic characteristics and results of an electromyography. Patients who started Korean medical treatment within 3 days of onset were placed in group A, within 9 days of onset in group B, and patients who started treatment after 10 days of onset were placed in group C. We tried to compare the level of facial nerve damage by electromyography between groups. Results : The patients in group C had the highest axonal loss rates in all branches(frontal, oculi, nasal, oris). The post hoc analyses revealed the difference of axonal loss rates between group A and B was not statistically significant. Only group C showed statistically higher axonal loss rates in all branches. Conclusion : The study results showed that the patients who had delayed Korean medical treatments had a higher level of facial nerve damage by electromyography. According to the results of this study, early application of integrative Korean medical treatment is suggested.

Quantitative Analysis of Myofascial Pain Syndrome in Trapezius Muscle Using Pressure Algometer and Surface Electromyography

( Shin-hye Kim ),( Yu-min Ko ),( Ji-won Park ),( Jong-in Youn ) 대한물리치료학회 2021 대한물리치료학회지 Vol.33 No.5

Purpose: Myofascial syndrome is a chronic muscle pain caused by repetitive motions with stress-related muscle tension. This study aimed to investigate the validity and reliability of the evidence for diagnosing myofascial pain syndrome in trapezius muscle using a pressure algometer and surface electromyography. Methods: The experiments were performed using a total of 10 subjects, and the target locations were determined by means of a pres-sure algometer in the right upper trapezius muscle. The part with the lowest pain value as the trigger point and the part with the highest pain value as the non-pain trigger point were selected for measuring the locations. The median frequency and average frequency were measured in those locations with electromyography. To check the muscle fatigue, the upper trapezius muscle was moved up and down for 2 seconds at 5-second intervals in 30 seconds. The measured values were evaluated using the independent paired t-test and Mann- Whitney U-test. Results: The median frequency at the non-trigger point (13.7) was significantly higher than that at the trigger point (7.3). Furthermore, the mean frequency (14.7) at the non-trigger point was significantly higher than that at the trigger point (6.3). Conclusion: The results showed the correlations between the trigger points of the muscle pain and frequency analysis of surface electro-myography. Thus, this study may be possible to use as a diagnostic tool for myofascial pain syndrome.

조민권,박종우,정이정 물리치료재활과학회 2016 Physical therapy rehabilitation science Vol.5 No.2

Objective: The purpose of this study was to compare the activation of trunk and gluteal muscles during bridge exercises with a sling (BS), single-legged bridge exercise with a sling (SBS), single-legged bridge exercise (SB), and general bridge exercise (GB). Design: Cross-sectional study. Methods: Twenty-five healthy participants (19 males and 6 females, aged 27.8 [4.78]) voluntarily participated in this study. In the bridging exercise, each subject lifted their pelvis with their legs and feet in contact with the sling or normal surface. The electrical activities of the erector spinae (ES), gluteus maximus (GM), external oblique (EO), and internal oblique (IO) muscles during the bridging exercises on the 2 surfaces were measured using surface electromyography. Subjects practiced each of the four bridge condition three times in random order and average values were obtained. Results: On the ipsilateral side, activities of the IO, EO, and ES during SBS was significantly higher than those during BS, SB, and GB (p<0.05). Activities of the IO and EO during SB was significantly higher than those during BS and GB (p<0.05). On the contralateral side, activities of the GM and EO during SB and SBS was significantly higher than that during BS and GB (p<0.05). These results verify the theory that the use of sling and single leg lift increases the activation trunk and gluteal muscles during bridging exercises. Conclusions: The single-legged bridge exercise with a sling can be recommended as an effective method to facilitate trunk and gluteal muscle activities.
