Purpose: The objective of this study is to evaluate the effect of neuro-feedback training and transcutaneous electrical nerve stimulation (TENS) on stress, quantitative sensory threshold and pain in patients suffering from tension type headache. Methods: 22 participants who passed the preliminary evaluation were enrolled in the study and 11 participants were randomly assigned to each group. The control group (n=11) was subject to the TENS treatment of which was composed of a 20-minute session for 5 times a week during 4 weeks, and the experimental group (n=11) was subject to both neuro feedback training and TENS treatment for 10 minutes a day and 5 days a week during 4 weeks. The Perceived Stress Scale (PSS) was used to measure a level of stress and the quantitative sensory testing (QST) was used for the measurement of cold pain threshold (CPT) and heat pain threshold (HPT); A degree of pain was evaluated through the headache impact test-6 (HIT-6). Results: In comparision of all dependent variables between the control and subject groups, there were significant differences in stress, quantitative sensory threshold and pain after the treatment (p<0.05), and the experimental group showed significant differences in stress, CPT, HPT and pain (p<0.05) and the control group showed only a significant difference in HPT (p<0.05). Conclusion: Findings of this study demonstrate that the concomitant administration of the TENS treatment and neuro feedback training is effective on alleviation of stress, quantitative sensory threshold and pain in patients with tension type headache.

Objective: This study was at investigated the effects of manual lymphatic drainage (MLD) on stress and pain in patients with postoperative breast cancer. Design: A randomized controlled trial. Methods: A total of twenty-two patients with postoperative breast cancer voluntarily participated in the study. Subjects were randomly assigned to the MLD groups (n=12) and rest groups (n=12). The intervention was conducted in each group for twenty minutes a day, five times a week, for four weeks. Before and after the intervention, the participants measured sympathetic nerve, parasympathetic nerve, and pain by using a sphygmograph and short-form McGill pain questionnaire.An independent t-test was used to analyze pretest and posttest changes between the groups, a paired t-test was used to analyze pre-posttests within each group. Results: After analyzing, the MLD group has been shown a significant decrease in the sympathetic nervous system (p<0.05), a significant increase in the parasympathetic nervous system (p<0.05), and a significant increase in pain (p<0.05). However, the rest group was no significant difference between pre and post. Conclusions: The results of this study confirmed that MLD techniques are an effective method in reducing stress and pain in patients with postoperativebreast cancer. And it is thought that can be used as basic data and to develop programs on stress and pain management reduction for patients with breast cancer.

The aqueous extract of Chungsimyeonja-eum has been used to treat palpitation, anemia, chronic fatigue, hypertension, and stroke. It also possesses various pharmacological effects including hypotensive, blood circulating, sedative, anti-inflammatory, diuretic, and anti-stress activities. In the present results, the latency time of plantar test was decreased in the immobilization stress and incusion pain-induction group. However the paw withdrawal latency values were increased in the immobilization stress and incision pain-induction groups after treatment with the aqueous extract of Chungsimyeonja-eum. The c-Fos expression in the paraventricular nucleus (PVN), and 5-hydroxytryptamine (5-HT) and tryptophan hydroxylase (TPH) in the dorsal raphe were enhanced in the immobilization stress and incision pain-induction groups. However, the treatment with the aqueous extract of Chungsimyeonja-eum suppressed the immobilization stress and incision pain-induced increase of c-Fos, 5-HT, and TPH expressions. Here in this study, we have demonstrated the protective effects of Chungsimyeonja-eum on immobilization and incision pain-induced stress. The present study revealed that Chungsimyeonja-eum treatment diminishes immobilization and pain stress.

The author studied the prevalence and sites of orofacial pain during the latest 6 months, and psychologic symptoms under the emotional stress through SCL-90-R in thirty-five dental students(nineteen men and sixteen women) of school of Dentistry, Chonbuk National University. 26 students(74.3%), 12 men and 14 women, experienced the orofacial pain; headache, toothache, facial & buccal pain, TMJ pain and intraoral pain were occurred in 51.4%, 37.1%, 25.7%, 17.1% and 17.1% respectively. In psychological scores in before-, during- and after examination, there was no significant difference between men and women. On the other hand, when these scores were compared each other in one group with orofacial pain experience and the other group without pain experience, the former showed significantly higher values in somatization, depression, hostility, and paranoid ideation dimension before examination, interpersonal sensitivity and anxiety dimension during examination, and somatization dimension after examination than those of the later group(P<0.05). The changes of psychologic symptoms in before-, during-, and after examination were observed in one group with pain experience and the other group without pain experience, respectively; in the former group the significantly higher values of anxiety dimension in during examination than after examination, and the significantly higher values of interpersonal sensitivity dimension in before examination than after examination(P<0.05) were evaluated.

Background: Despite the enormous amount of basic research on neuropathic pain, there is the lack of an objective diagnostic test for complex regional pain syndrome (CRPS). The aim of this study was to evaluate the usefulness of cold stress thermography in the diagnosis of CRPS. Methods: The study involved 12 patients with CRPS type 1, according to the IASP criteria, who were compared with 15 normal healthy volunteers. All subjects underwent thermographic examination under baseline conditions at $21^{\circ}C$. A cold stress test (CST; $10^{\circ}C$ water for 1 minute) was then applied to both hands below the wrists, immediate, and after 10 and 20 minutes. Results: The temperature asymmetry between the patients with CRPS and the volunteers showed significant discrimination at the baseline and after a 20 minute recovery period from the CST. Among the study subjects having temperature asymmetry of both hands of less than $1^{\circ}C$ (8 out of 12 CRPS patients and 14 out of 15 volunteer), 7 (87.5%) of the 8 CRPS patients and 3 (21%) of the 14 volunteers showed a temperature difference of more than $1^{\circ}C$ after the 20 minute recovery period. The actual temperature values during the four periods did not discriminate between the patients with CRPS and the volunteers. Conclusions: Thermography, under the CST, could be a more objective test for the diagnosis of CRPS. A temperature asymmetry greater than $1^{\circ}C$ during the 20 minute recovery period following CST provides strong diagnostic information about CRPS, with both high sensitivity and specificity.

Objectives : The object of this study was to investigate the relationship between coping strategies and perceived stress or pain discomfort in patients with chronic low back pain. 80 patients with chronic low back pain and 100 normal controls participated in this study. Methods: Global assessment of recent stress (GARS) scale and Stress Response Inventory (SRI) were used to measure perception for stressors and stress responses. Coping scale and pain discomfort scale were used to measure coping strategies and pain perception. Results : Scores of perceived stress related to work or job, interpersonal relationship, changes in relationship, sickness or illness and the total scores on the GARS scale were significantly higher in those with chronic low back pain than normal controls. Scores of the SRI fatigue subscale scored significantly higher in those with chronic low back pain than normal controls. No significant difference was found on total scores of the pain discomfort scale between those with chronic low back pain and normal controls. The patients with chronic low back pain scored significantly higher on planful problem solving and positive reappraisal than normal controls. In the patient group, pain perception had significant positive correlations with total scores of the SRI and scores of stress perception related to illness or injury. The extent of escape-avoidance showed significant negative correlations with age, whereas the extent of distancing or escape-avoidance had significant negative correlations with the level of education. Significant difference was also found in accepting responsibilities between male subjects and females. However, no significant correlations were found between coping strategies and perceived stressors, stress responses or pain perception. Conclusion : The results suggest that patients with chronic low back pain were more likely to use more active coping strategies than normal controls, though the former had more perception for stressors than the latter. It was also found that coping strategies used by the patients were associated with sociodemographic factors, but that they were not associated with perceived stressors, stress responses or pain perception.

Purpose: To quantify the relationship between perceived pain intensity and psychological variables in a sample of participants with temporomandibular disorder, with or without central sensitization (CS). Methods: A cross-sectional study with nonprobability convenience sampling was conducted from January 1, 2022, to June 30, 2023. Pain intensity (Numeric Pain Rating Scale), anxiety (State-Trait Anxiety Questionnaire, STAI), catastrophizing (Pain Catastrophizing Scale, PCS), perceived stress (Perceived Stress Scale, PSS), and sleep quality (Pittsburgh Sleep Quality Index, PSQI) were assessed. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Co.), which included descriptive and normality analyses and the calculation of strength of multiple correlational regression. Results: A total of 52 (n=34 female 65.4%; n=18 male 34.6%) subjects with diagnosis of temporomandibular disorders (TMD) were finally included. A total of 26 participants (n=26, 50.0%) were cases suffered from CS (TMD-CS mean=46.62±11.24) while the remaining participants (n=26, 50.0%) were the controls (TMD-nCS mean=26.77, standard deviation [SD]=8.42). The pain intensity was moderate in both groups TMDCS (mean=7.62, SD=0.83) and TMD-nCS (mean=7.05, SD=0.86), anxiety (TMD-CS STAI mean=53.27, SD=11.54; TMD-nCS STAI mean=49, SD=11.55), catastrophizing (TMD-CS PCS mean=46.27, SD=9.75; TMD-nCS PCS mean=26.69, SD=4.97), perceived stress (TMDCS PSS mean=30.35, SD=4.91; TMD-nCS PSS mean=26.12, SD=6.60) and sleep quality (TMD-CS PSQI mean=15.81, SD=3.65; TMD-nCS PSQI mean=12.77, SD=2.76) levels were measured in both groups. In TMD-CS and TMD-nCS, higher anxiety levels were moderately and significantly associated with greater pain intensity β=0.4467 (t=2.477, p=0.021) and β=0.5087 (t=2.672, p=0.014). Nevertheless, catastrophizing, perceived stress and sleep quality were not associated to pain intensity in neither of group. Conclusions: In both TMD-CS and TMD-nCS patients, elevated anxiety levels were moderately and significantly associated with increased pain intensity. However, heightened levels of pain catastrophizing, perceived stress, and poor sleep quality were not significantly associated with increased pain intensity in either of the two analyzed groups.

Many diseases occur by stress or effect of stress. The basis for using hormones in research of stress is the observation that most systems in the body show changes during stress and that hormonal markers in these changes are related with stress. Conceptually, the central role of sympathetic nervous system(SNS) and hypothalamus-pituitary-adrenal(HPA) axis activity in stress provides copious justification for measuring hormonal changes. Catecholamines like epinephrine and norepinephrine, cortisol, testosterone and growth hormone and so on show sensitive reaction to stress. The major advantage of salivary sample to stress research is that its sampling technique can be performed in non-stressful conditions and without physical restraint and ethical problems. Because hormone levels in saliva is a good reflection of hormone levels in plasma, application of stress hormones in saliva is very useful for research of orofacial pain related with stress.

The purpose of this study was to investigate the menstrual pain, clinical practice stress, and clinical competence and identify influencing factors of clinical competence of 3rd nursing students who start clinical practice for the first tim. The survey was conducted on 155 nursing students from June 1 to October 30, 2020. Data were analyzed using t-test, ANOVA, Scheffe test, Pearson correlation coefficients and multiple regression analysis. The degree of influence menstrual pain was 5.01points, clinical practice stress was 2.82points, clinical competence was 3.42points. Menstrual pain was positive correlated with clinical practice stress(r=.319, p=.000), and menstrual pain was negative correlated with clinical competence(r=-.279, p=.000). Clinical practice stress was negative correlated with clinical competence(r=-.333, p=.005). Menstrual pain was main factor that affects clinical competence. The model explained 25.0% of the variables. Therefore, intervention education is needed to reduce menstrual pain in order to improve the clinical competence of nursing students.
