The purpose of this study was to evaluate the effect of experimenter gender on pain report as well as the sex differences in pain threshold and pain tolerance. Cold pressor test and pressure pain threshold (PPT) test were performed on forty dental students by both of a male and a female experimenter separately with 1 day interval. The obtained results were as follows : There were no differences in pain threshold and pain tolerance between males and females when they were examined by the same gender experimenter in the cold pressor test, but when they were examined by the opposite gender experimenter the pain threshold of males was significantly higher than females. When the pain threshold was measured by the same gender experimenter, using a algometer, there was no differences in PPT between males and females. However, when the same measurements were done by the opposite gender experimenter, the PPT of males was significantly higher than females at anterior temporalis and inferior masseter. For cold pressor test, females tended to report lower levels of pain threshold and pain tolerance to a male experimenter than a female, but the differences were not significant. Although both pain threshold and pain tolerance were increased when males were examined by a female experimenter in the cold pressor test, the statistical significance was found only in pain tolerance. When subjects were examined by the opposite gender experimenter in the PPT text, females reported significantly higher levels of pain at inferior masseter and males reported significantly lower levels of pain at anterior temporalis and inferior masseter.

Objective: The purpose of this study was to evaluate the effects of temporomandibular joint and cervical vertebra treatment in persons with tension-type headaches on pain, tenderness, and functional improvement. Design: Three-group pretest-posttest design. Methods: Subjects with tension-type headaches were divided into the temporomandibular joint and cervical vertebra treatment group (n=11), temporomandibular joint treatment group (n=11), and cervical vertebra treatment group (n=11), and pre- and post-evaluation was performed. The temporomandibular joint treatment group underwent compression massage and joint ply of the muscles around the temporomandibular joint. The cervical vertebra group received deep tendon massage and Myofascial Release of the cervical muscles. The temporomandibular joint and cervical vertebra treatment group performed both types of treatment. Treatment was performed for 50 minutes, three times a week for 4 weeks. Measurement tools included the Korean version of the short form-McGill Pain Questionnaire (SF-MPQ, K), Headache Impact test-6 (HIT-6), Neck Disability Index (NDI), and the Digital Algometer FPX25. Results: The groups showed significant differences in SF-MPQ, HIT-6 test, NDI, and Alogometer FPX25 test scores before and after intervention (p<0.05). The differences between the groups were most significant in the group that received treatment of the temporomandibular joint and cervical vertebra (p<0.05). Conclusions: In this study, the treatment of the temporomandibular joint and cervical vertebra was shown to be effective for improving pain, quality of life, and cervical vertebra in persons with tension-type headaches. This data may be helpful in identifying treatment techniques for tension-type headaches in the future.

Objectives : The aim of this study was to investigate difference of the effects of transcutaneous electrical nerve stimulation(TENS) with different frequencies in participants having delayed onset muscle soreness(DOMS). Methods : We recruited 36 healthy participants, but 3 of them were dropped out. They were randomly divided into 3groups : 3 Hz TENS(n=11), 100 Hz TENS(n=11) and sham TENS(n=11). DOMS of the both triceps surae muscle induced by repetitive concentric, ecentric exercise. The result measurements were pain perception(visual analogue scale, VAS), mechanical pain threshold(MPT) by pressure algometer, electrical contraction and fatigue by surface electromyography. The measurements were on first visit, before and after treatment except first. This study was prospective, randomized, controlled, single-blinded trial. Results : In 100 Hz TENS group, VAS was significantly decreased during whole session compared with 3 Hz and control group, and after each treatment, too. In 3 Hz TENS group, VAS was significantly decreased during whole session compared with control group, and after 2nd, 3rd treatment, too. In 100 Hz TENS group, MPT increased the most among 3 groups during whole session and after 1st treatment, but there were no statistical significances. Conclusions : Both 3 Hz and 100 Hz TENS improved delayed onset muscle soreness, but 100 Hz TENS group is more effective than 3 Hz TENS group.

Objects: This study aimed to evaluate the role of somatic delusion on the pain perception in patients with schizophrenia. It was hypothesized that pressure pain thresholds would be rather higher in schizophrenic patients who had somatic delusion than patients with other delusion. Methods The subjects were consisted of 3 groups, 23 men with schizophrenia who had somatic delusion, 25 men with schizophrenia who had other delusion, and 22 normal healthy controls. By using Algometer, pressure pain thresholds were examined to subjects on three non-tender sites with 6 weeks interval. The severity of delusion was evaluated in both patient groups. Statistically, Chi-square test, One-way ANOVA, Multivariate ANOVA, and Scheffe's test were used. Results : 1) There was significant difference between somatic and other delusion groups and normal control group at initial stage. 6 weeks later even when severity of delusion was thought to be ameliorated, this finding were sustained. 2) The severity of the components of delusion, conviction and preoccupation, were significantly decreased in both somatic delusion group and other delusion group according to the time interval. The decrements of the severity of delusion seems to be related with changes in pressure pain thresholds in both patient groups. Conclusions : We re-confirmed that both schizophrenic patient groups showed higher pressure pain thresholds compared to normal healthy control. However we failed to find the role of somatic delusion on pain perception in schizophrenia. Delusion, including somatic delusion, as a whole, seems to affect the increased level of pressure pain threshold due to attention deficit and decreased motivation in patients with schizophrenia.

Objective: This study aimed to identify the area with greatest effect using self-myofascial release technique (self-MFR) in the hamstring, suboccipital, and plantar regions. Design: Cross-sectional study. Methods: Twenty-two adult subjects were evaluated for flexibility and hamstring pain threshold after self-MFR. Based on the superficial back line, the self-MFR application areas were the suboccipital region, hamstring, and plantar regions. Self-MFR was applied to each area using a wooden pole for a total of 4 minutes. Self-MFR was applied for 3 days at the same time of day, which was randomly assigned for each subject. Treatment was applied to one area each day. The sit and reach test (SRT), active range of motion (AROM), and passive ROM (PROM) were used to determine changes in flexibility, and an algometer was used to determine pain threshold. Pre/post-self-MFR effectiveness was tested using a paired t-test. Repeated measurement was used to compare self-MFR effects in the suboccipital, hamstring, and plantar regions. Results: When the self-MFR technique was applied to the 3 areas, the SRT showed significant improvement over baseline (p<0.05). Bilateral AROM and PROM showed significant improvements (p<0.05). When the self-MFR technique was applied to the hamstring, the semimembranosus showed a significant change in pain threshold (p<0.05). Conclusions: Our findings suggest that indirect application based on the Anatomy Trains could be effective for those who need to improve muscle flexibility. Moreover, self-MFR easily alleviates myofascial pain while maintaining flexibility, and can be performed at any time and place.

Purpose: This study was to determine the immediate effects of pulsed magnetic field (PMF) in subjects with upper trapezius (UT) trigger point (TrP). Methods: Fifteen subjects with UT TrP were recruited for the study's PMF group (pain threshold=$2.29kg/cm^2$), and 15 age-, weight-, and gender-matched subjects with UT TrP were recruited for control group (pain threshold=$2.25kg/cm^2$). Pressure algometer was used to measure pressure pain threshold on UT TrP and, cervical range of motion (ROM) inclinometer was used to measure cervical ROM. Surface electromyography was used to record UT, lower trapezius, and serratus anterior muscle activity and relative ratio during scapular plane abduction between pre- and post-treatment. Results: The PMF effectively improved pain threshold and concurrently increased ROM (rotation to the painful side, lateral flexion to the nonpainful side). In addition, the PMF may effectively deactivate UT activity during abduction and the muscle activity ratio between UT and serratus anterior. Conclusion: These findings provided empirical evidence that PMF can be an effective treatment method to reduce pain threshold, to increase cervical ROM, and deactivate UT activity in individuals with TrP.
