Purpose : The purpose of this study is to compare muscle activity after applying two muscle energy techniques (MET) to subjects with forward head posture to see if the post isometric relaxation (PIR) technique is more effective than the reciprocal inhibition (RI) technique. Methods : The muscle activity was measured using EMG after applying the PIR and RI techniques to 30 adults at K College. Subjects were selected for forward head posture whose ear center was 2.5 ㎝ front of the center of the shoulder. EMG equipment was used to measure muscle activity, and the measurement sites were measured in cervical flexor and extensor muscles. The experiment period was performed once a week for a total of two weeks, and after the pre-measurement was performed for 5 minutes PIR and RI exercise. In the PIR technique, the head is tilted back in a sitting position, and the experimenter applies resistance with the same force for 7~10 seconds and repeats 3-5 times after rest. In the RI technique, in a sitting position, the subject gives the force to bend the head forward, and the experimenter applies resistance with the same force for 7 to 10 seconds, and repeats 3 to 5 times after rest. Results : The result is same as the following. In the comparison of muscle activity, there was a significant decrease in both PIR and RI at 1 and 2 weeks. And there was a greater decrease in muscle activity in PIR. There was no difference in the comparison of decrease in muscle activity at 1 week and 2 week. Conclusion : Both PRI and RI can be said to be effective in improving the function of the forward head posture in the neck muscles. Therefore, the selection of the two techniques in clinical practice should be appropriately performed under the judgment of experts according to the patient's situation.

Background: The purpose of this study is to investigate the effect of muscle energy technique and stretching on pain and pressure pain fear-avoidance beliefs questionnaire in patients with chronic back pain aged 30~40 years. Design: Pretest-Posttest design: single blind. Methods: The subjects of this study were 30, 22 males and 8 females between the ages of 30 and 40 with chronic back pain. Each group consists of three groups of 10 people. Changes in back pain were observed using Korean version of Oswestry Disability Index (K-ODI), visual analogue scale (VAS), and fear-avoidance beliefs questionnaire (FABQ). And the change in tenderness was observed using digital pressure statistics. Changes between groups after 3 weeks were compared with those before the experiment using one way ANOVA to determine the changes after 3 weeks. And the change within the group was investigated using the paired t-test. Results: As a result of the experiment, there were significant differences in the group changes in K-ODI, VAS, FABQ, and pressure pain (p<0.05). And there was a significant difference in all items after 3 weeks compared to before the experiment (p<0.05). Conclusion: In patients with chronic back pain, the muscle energy technique and stretching gave a significant difference in pain and pressure pain, fear-avoidance beliefs questionnaire changes. And this result suggests the possibility of providing basic data for future research and clinical physiotherapy intervention.

Background: Low back and neck pain are two of the most common medical problems in the adult population. It is estimated that between 70% and 80% adults experience an episode of low back pain at least once during their lifetime. Objects: This study aimed to compare the effects of various stretching exercises and muscle energy techniques used for treatment of iliopsoas, quadratus lumborum, and hamstrings of patients with low back pain. Methods: A total of 52 subjects were randomly assigned to the control group (n = 17), the muscle energy technology group (METG, n = 19), and the stretching exercise group (SEG, n = 16). Interventions were performed twice a week for 4 weeks. Outcomes were measured before and after 4 weeks of treatment in the three groups, using the Korean version of the Oswestry Disability Index, the Visual Analogue Scale (VAS), the Fear Avoidance Belief Questionnaire (FABQ), the Finger to Floor test (FTF), the Modified-Modified Schober Test (MMS), and the Trunk Flexion Range of Motion test. Results: This study showed significant reduction in the pre-test and post-test KODI, VAS, and FABQ scores in all the three groups (p < 0.05). The KODI, VAS, FABQ and FTF assessed in this study showed interactions between the groups and the measurement time point (p < 0.01). After intervention, the KODI, VAS, FABQ and FTF in the SEG and METG were significantly higher (p < 0.05), and there was no difference between the METG and SEG. MMS and HFROM test showed no difference between the three groups (p > 0.05). Conclusion: KODI, VAS, FABQ and FTF showed significant improvement after basic physical therapy, muscle energy technique, and stretching exercise intervention. And there was no significant difference in the intervention effect between the muscle energy group and the stretching exercise group.

Objectives : The purpose of this study was to provide a clinical evidence base for the effectiveness of the muscle energy technique (MET) for cervicalgia. Methods : We conducted a search of 10 electronic databases up to April 2019. Randomized controlled trials (RCTs) that performed the MET for cervicalgia were included. The risk of bias was assessed using the Cochrane risk of bias (RoB) tool. Results : Six RCTs met the inclusion criteria. The literature review of these studies showed favorable results for the use of the MET in comparison to other manual medicines. Conclusions : In 6 RCTs, we found that the MET was effective in cervicalgia treatment. However, most of the included studies had an unclear risk of bias. Therefore, well-designed RCTs are necessary to obtain a higher evidence level of the MET use in cervicalgia.

Purpose: This study examined whether a single application of a lumbar flexion muscle energy technique (MET) could significantly influence pain, functional status, and range of motion in chronic back pain patients with restricted active trunk flexion. Methods: Twenty volunteers were randomly assigned to either a control group or an experimental group. Ten subjects in the control group received no treatment. Ten subjects in the experimental group received five sessions with the muscle energy technique, five times per week for two weeks. Outcomes were measured before and after two weeks of treatment in both groups. Pain intensity was assessed using a visual analogue scale (VAS). Range of motion was measured using the sit-and-reach test (SRT). Functional disability levels were assessed using the Korean version of the Oswestry Disability Index (KODI). Results: The experimental group showed a significant difference in VAS, KODI, and SRT between pre- and post-treatment (p < .05), while the control group showed no significant changes. The changes in VAS, ODI, and SRT were statistically significant between the groups pre- and post-treatment (p < .05). Conclusion: This muscle energy technique is clinically effective for chronic low back pain patients.

Background: This study examined the effects of the muscle energy technique and cervical traction after applying conservative physical therapy in patients with cervical radiculopathy. Methods: Patients were randomly divided into two groups muscle energy technique (8 subjects) and cervical traction (8 subjects). Each group performed their exercise 70 minutes per day, three times week for four weeks. Pain intensity was measured with a visual analogue scale (VAS). Function was measured with the neck disability index (NDI). Cervical range of motion (ROM) was measured with a cervical range of motion (CROM) goniometer. Results: After four weeks of therapy, VAS (p<.05) and NDI (p<.05) significantly decreased, and ROM significantly increased in both groups (p<.05). There were also significant differences between the two groups for these three measures (p<.05). Conclusion: The muscle energy technique and cervical traction are more effective than cervical traction alone in reducing VAS and NDI and increasing ROM in patients with cervical radiculopathy.

가뭄의 경우 타 자연재난에 비해 발생경로, 피해범위, 발생기간 등이 매우 다양해 다각적인 측면에서의 대응책 마련이 필요하다. 따라서, 극한가뭄에 대비한 지자체별 가뭄 역량 평가를 수행하는 것은 재난관리에 있어서 최우선이라고 할 수 있다. 현재 국내외적으로 가뭄과 관련된 지역적 복원력을 평가한 사례는 매우 적다. 가뭄은 지진, 홍수 등과 같은 타 자연재난에 비하여 지속기간이 길고, 그 지속기간에 따라 피해의 영향 또한 파급력이 달라지므로 복원력 산정을 위한 항목, 복원력 곡선의 저하 형태 및 양상 역시 가뭄의 특성에 맞춰 도출되어야 한다. 본 연구에서는 지자체별 극한가뭄에 대한 복원력 정량화를 위하여 가뭄과 관련된 내구성, 대체성, 신속성, 자원동원력의 세부인자를 정성인자와 정량인자로 구분하여 총 18개 항목으로 구성하였다. 구성된 18가지 항목이 정량인자 뿐만 아니라 정성인자로 구성됨에 따라, 모든 인자를 동일한 가중치로 평가할 경우 최종결과가 상대적 중요도의 미 고려로 인해 왜곡될 가능성이 존재한다. 따라서 계층적분석기법(AHP, Analytic Hierarchy Process)을 통해 내구성, 대체성, 신속성, 그리고 자원동원력에 대한 가중치와 내구성, 대체성, 그리고 신속성에 대한 세부 지표별 가중치를 도출하여 지역별 메가가뭄 복원력을 정량화 하였다. 분석결과를 동일한 가중치를 적용한 결과와 비교분석하였으며, 과거 가뭄사례를 통해 검토하였다.
