The aim of this study was to determine whether T.M.J. tomographic examination yielded significant differences in condyle positions among asymptomatic, myalgia, derangement, and arthrosis groups of T.M.J. disorders. The author obtained sagittal linear tomograms of right and left T.M.Js. of 36 asymptomatic, 22 myalgia, 54 derangement, and 31 arthrosis patients taken at serial lateral, central, and medial sections in the intercuspal position after submentovertex radiographs analyzed. With the dual linear measurements of the posterior and anterior interarticular space, condyle positions were mathematically expressed as proportion. All data from these analysis was recorded and processed statistically. The results were obtained as follows. 1. In asymptomatic group, radiographically concentric condyle position was found in 50.0% to 65.4% of subjects, with a substantial range of variability. No significant differences existed between men and women and also between right and left T.M.Js. for condyle position. 2. In women, significant difference for mean condyle position of left lateral section of each diagnostic category existed between derangement and myalgia groups (P<.05). Also that of left central section existed between derangement and myalgia groups, and that of left medial section existed between derangement and myalgia groups (P<.05). 3. In main-symptom side, condyle position in myalgia group was more concentric, and condyle position in derangement group was more posterior. This showed significant differences between derangement and myalgia groups in lateral, central, and medial sections of main- symptom sides, and only between derangement and myalgia groups in central section of contra-lateral sides (P<.05). Condyle position in arthrosis group was broadly distributed among all positions. 4. In contra-lateral side, significant difference for mean condyle position of central section of each symptomatic group existed between derangement and myalgia groups (P<.05). Condyle position in derangement group was more posterior. The distribution of the condyle position of contra-lateral side in patients with unilateral symptoms was similar to that of main-symptom side in each symptomatic group. No significant difference existed between main-symptom and contra-lateral sides. 5. For internal derangement subgroups, condyle position in reducible disc displacement group was more posterior than non-reciprocal and locking groups, but there was no significant difference. 6. From 16 to 25 years, significant difference for mean condyle position of medial section of main-symptom side of each symptomatic group existed between myalgia and derangement groups (P<.05).

Background: The options for stabilization appliance therapy for masticatory muscle pain include soft occlusal and hard stabilization appliances. A previous study suggested that hard stabilization appliance therapy was effective for patients with local myalgia who developed long facets on their occlusal appliances. The objective of this study was to identify patients in whom a soft occlusal appliance should be used to treat masticatory muscle pain by analyzing the type of muscle pain present and patient factors that influenced the effectiveness of this treatment. Methods: The study included 42 patients diagnosed with local myalgia or myofascial pain according to the Diagnostic Criteria for Temporomandibular Disorders Diagnostic Decision Tree. The analysis of patient factors included variables believed to be associated with temporomandibular disorders. First, a temporary screening appliance was used for 2 weeks to assess each patient for bruxism during sleep. Soft appliance therapy was then started. For each patient, the effectiveness of the appliance was evaluated according to the intensity of tenderness during muscle palpation and the treatment satisfaction score at one month after starting treatment. Results: Data from 37 of the 42 patients were available for analysis. Twenty-five patients reported satisfaction with the appliance. In logistic regression analysis, the odds ratio for reduction of facet length was 1.998. Nineteen patients showed at least a 30% improvement in the visual analog scale score. The odds ratio for local myalgia was 18.148. Conclusion: Soft appliance therapy may be used in patients with local myalgia. Moreover, patients who develop short facets on the appliance surface are likely to be satisfied with soft appliance therapy. Soft appliance therapy may be appropriate for patients with local myalgia who develop short facets on their occlusal appliance.

Although most cases of tension-type headache(TTH) are myogenic headache, in some cases, arthralgia appears, such as the disorder of the temporamandibular joint. This study is designed to compare the clinical patterns of arthralgia to those of myalgia, when both symptoms are co-existing. Among 167 patients who visit our clinic during a certain period, whose chief complaint was TTH, 18 patients were the arthralgia group, 50 patients were the myalgia group, and 99 patients who have both arthralgia and myalgia were the arthromyalgia group. Three groups were asked to answer the questionnaires about their age, gender, and oral parafunction such as bruxism or clenching. Then we gathered statistics on the data from the accomplished questionnaires. 1. There was statistical significance in age among the three groups(p=0.02). 2. There was no statistical significance in sex and oral parafunction among the three groups. 3. There was statistical significance the myalgia group was older than the arthromyalgia group(p<0.03). The results of the study show that as patients become older, TTH with myalgia happens more frequently than TTH with arthralgia and myalgia does.

This study was to determine whether iontophoresis application of centipede venom would produce analgesic effect for clinical practice. Sixty patients suffered from musculoskeletal diseases who lived in Taejon city were analyzed by double-blind central study. After pre treatment, post treatment, post 20 minutes, post 40 minutes iontophoresis using centipede venom, we assessed the response to pin-prick sensation with Endomed 582 in myalgia patients. The results were as follows, control group showed pain threshold of 1.76, 2.03, 2.01, 2.02mA after treatment, but the pain threshold of 1.76, 2.21, 3.85, 3.87mA after iontophoresis application in study group. The pain threshold of Notermans pain score after 20-minute and 40-minute centipede venom iontophoresis group using centipede venom was higher than that after non-centipede venom iontophoresis group. The results showed that by the increasing the analgesic effect in the centipede venom iontophoresis group, especially in time of post 20 minutes after iontophoresis treatment. So we considered that the iontophoresis using centipede venom could be reduced pain of myalgia in musuloskeletal disease patients.

Purpose: To search the salivary factors that objectively indicate an pain in myalgia patients with temporomandibular joint disorder (TMD) and determine the possibility of the factors as pain-biomarkers. Methods: Participants consisted of pain-free 15 persons (male 7, female 8, mean age±standard deviation (SD); 26.8±16.04 years) and 45 myalgia patients with TMD (male 21, female 24, mean age±SD; 27.98±13.01 years). They were divided into a pain-free group (numerical rating scale [NRS] score 0), a mild pain group (NRS 1-4), a moderate pain group (NRS 5-6), and a severe pain group (NRS 7-10) and members of all groups were age, sex matched. Interleukin-8 (IL-8) and matrix metalloprotease 9 (MMP-9) were selected as pain biomarkers, by searching the Gene Expression Omnibus database and analyzing pain-related genes. Enzyme-linked immunosorbent assays were used to measure the concentration of IL-8 and MMP-9 in the patients' saliva. Results: IL-8 and MMP-9 levels were statistically significantly higher in pain groups than in the pain-free group. Greater differences were observed in patients with acute pain (with painful duration under 3 months) than in the control group and in female patients than in male. Conclusions: Salivary IL-8 and MMP-9 may play a role as biomarkers of myalgia in patients with TMD.

Purpose: The purpose of this study was to investigate symptoms experienced by patients who reported fever at the emergency room (ER) and to identify any existing cluster of symptom related to fever. Methods: The study used a retrospective and descriptive design with secondary data analysis. Data were abstracted from 665 medical records of patients with fever who visited ER from September 1, 2015 to August 31, 2016 at a tertiary hospital. Results: The most frequently reported symptoms included cold (43.9%), myalgia (24.1%), headache (16.2%), general weakness (15.3%), respiratory symptoms (12.3%), gastrointestinal (GI) symptoms (12.0%), mental change (4.5%), sweating(1.8%), and warmth (0.9%). Analysis of the symptoms related to fever revealed seven symptom clusters; Cluster 1 (n=190) included cold (100%) and myalgia (28.9%); Cluster 2 (n=37), headache (100%) and myalgia (32.4%); Cluster 3 (n=33), GI symptoms (100%), general weakness, headache, and cold; Cluster 4 (n=34), cold (100%), myalgia, headache, and respiratory symptoms; Cluster 5 (n=241), respiratory symptoms (10.8%); Cluster 6 (n=76): myalgia (75.0%) and general weakness, and Cluster 7 (n=54), cold (87.0%), general weakness, and respiratory symptoms. Conclusion: The results of this comprehensive symptom assessment are hoped to be helpful in developing better symptom management for ER patients with fever than before. Further research is warranted to verify the symptom clusters of this study in different clinical settings.

Objectives The purpose of this study is to investigate the efficacy of E10 on the relief of cervical myalgia. Methods This study is a one group pre-post, pilot trial test. After the approval of institutional review board (IRB), we have recruited 25 patients suffering from cervical myalgia. 23 patients (2 patients dropped out) was treated by using E10 on the cervical muscle and acupuncture points, three times a week for a total of two weeks from February 2016 to April 2016. Evaluations of VAS for bothersomeness of neck pain (VASB), VAS for pain intensity (VASP), NDI, SF-36, X-ray, thermography, etc. before and 1 week after treatment were carried out. The primary outcome measure was the VASB, measured 1 week after the end of the therapy. Results VASB scores was significantly decreased from $72.5{\pm}9.9$ to $50.4{\pm}9.9$. VASP scores was significantly decreased from $71.5{\pm}10.5$ to $48.5{\pm}18.3$. Results showed significant improvements in VASB, VASP, NDI, SF-36 from the baseline. However, in X-ray, thermography, there was no singnificant difference. Conclusions This study demonstrates the effectiveness of E10 treatment for relieving cervical myalgia.

Patients often seek consultation with dentists for their temporomandibular disorders (TMD), especially for pain. Acute pains refer to pains that are of short duration. Common acute TMD are arthralgia and local myalgia. Diagnosis should be made based on careful history taking and clinical examination. Most acute TMD are well controlled by education, cognitive awareness training, and conservative treatment. The aggressive and irreversible treatments should not be applied. Acute TMD should be controlled in the early phase so as not to be proceed to chronic pain.

Purpose: This study aimed to investigate whether and how the biopsychosocial features of myofascial pain (MFP) differ from those of local myalgia (LM) in temporomandibular disorder (TMD). Methods: Patients with TMD were retrospectively evaluated using the Diagnostic Criteria for TMD. All patients completed a series of self-administered questionnaires on pain severity and pain interference (Brief Pain Inventory, BPI), pain disability (Graded Chronic Pain Scale, GCPS), psychological distress (Symptom Check List-90-Revised, SCL-90R), pain cognition (Pain Catastrophizing Scale, PCS), and subjective sleep quality (Pittsburgh Sleep Quality Index, PSQI). Among all the TMD diagnoses, muscle pain was classified into the MFP group and LM group. Results: This study included 917 patients with myalgia (MFP: 266, LM: 651). Significant differences were observed in the female ratio (78.9% for MFP, 60.9% for LM, p<0.001) and the mean pain duration (MFP: 25.3 months, LM: 15.8 months, p=0.001) between the two groups. Patients with MFP exhibited higher pain severity (p=0.003) and pain interference (p<0.001) of BPI than those with LM. Furthermore, the global scores of the PCS (p<0.001) and PSQI (p<0.001) were higher in the MFP group than in the LM group. The MFP group had higher global symptom index (p=0.017) and five subscales of the SCL-90R than the LM group. Compared with the LM group (33.4%), the greater proportion of high disability of GCPS was observed in the MFP group (44.9%) (p<0.001). Multiple regression analysis revealed that sex (p=0.002), pain duration (p=0.019), pain disability (p=0.010), and subjective sleep quality (p=0.008) significantly differed between the two groups. Conclusions: The findings of this study indicated that MFP presents a higher biopsychosocial burden than LM in TMD.
