Electromyographic changes in masseter and sternocleidomastoid muscles can be applied to diagnose of temporomandibular disorders: An observational study.

BACKGROUND: The diagnosis of temporomandibular disorders (TMDs) is an important part of the functional cerebrospinal technique (FCST). In addition, surface electromyography (sEMG) is an important candidate for diagnosing TMD. In FCST, despite the importance of the cranio-cervical-mandibular system, few sEMG parameters consider TMDs. Thus, this study evaluated the possibility of TMD diagnosis by sEMG. METHODS: The study was conducted as an assessor-blinded cross-sectional study. Each of 35 participants were recruited for patient group and normal group separately based on the Diagnostic Criteria for TMD Symptoms Questionnaire (DC/TMD SQ). The sEMG was measured by attaching electrodes to sternocleidomastoid muscles (SCMM) and masseter muscles (MM) before and after wearing the temporomandibular joint balance appliance (TBA). RESULTS: The percentage overlapping coefficient (POC) value of the healthy control group was increased compared with the TMD group. Receiver operating characteristic (ROC) analysis revealed that the area under the curve (AUC) value of the SCMM was greater than that of the MM. POC values before and after the SCMM also revealed significant changes compared to the MM. CONCLUSION: This study showed that the sEMG measurement of the SCMM is useful for TMD diagnosis in traditional Korean medicine.

Difference between Right and Left Facial Surface Electromyography in Healthy People.

INTRODUCTION: The study was to see whether there were differences in values of facial surface electromyography in subjects of good heath by muscles, age, and sex. METHODS: It draws ratio between lower value and higher value (R-LV/HV) and asymmetry index (AI), based on root mean square (RMS) from measurement of facial surface electromyography (sEMG) in 154 people of healthy people (male:female = 70:84) aging between more than 20 and less than 70. RESULTS: For R-LV/HV, it averages 81.70±14.60% on frontalis muscle, 73.74±19.12% on zygomaticus muscle, and 79.72±14.77% on orbicularis oris muscle. With analysis of the AI average was 10.87±10.14% on frontalis muscle, 16.71±14.79% on zygomaticus muscle, and 12.10±10.05% on orbicularis oris muscle. Both values were statistically significant in three parts of muscles as shown. Both of R-LV/HV and AI show no statistically significant difference on age and sex (p>0.05). CONCLUSIONS: It could provide basic data for the future diagnosis of facial nerve palsy patients by measuring facial sEMG values for healthy people.

Development of electromyographic indicators for the diagnosis of temporomandibular disorders: a protocol for an assessor-blinded cross-sectional study.

BACKGROUND: Noninvasive and easy-to-use surface electromyography (EMG) is frequently utilized for the diagnosis of temporomandibular disorders (TMDs). However, few EMG parameters that consider TMDs in addition to the cranio-cervical-mandibular system have been regarded as important in traditional Korean medicine. METHODS: This clinical trial will be conducted as an assessor-blinded cross-sectional study. The participants will be classified based on the Diagnostic Criteria for TMDs Symptom Questionnaire (DC/TMD SQ) and 30 TMD patients and 30 healthy controls will be enrolled. The primary outcome will be the percentage overlapping coefficient (POC; %) in the masseter and sternocleidomastoid muscles between the patient group and healthy control group in clenching and cervical side flexion. The secondary outcomes include the score from temporomandibular joint-related questionnaires, the difference in the absolute values of EMG for the healthy group and TMD group before/after wearing intraoral appliances, and the change in the location of the temporomandibular joint as determined by X-ray imaging and 3D face photography. DISCUSSION: This study will provide information about the objective diagnostic method for TMD using surface EMG and will verify the effectiveness of surface EMG in diagnosing TMD. Furthermore, the method or device for diagnosis TMD will improve the expansion of treatment area to TMD by accumulating evidence for the efficacy of TKM treatment.

Acupuncture for treating attention deficit hyperactivity disorder: a systematic review and meta-analysis.

OBJECTIVE: To assess the effectiveness of acupuncture as a treatment option for attention deficit hyperactivity disorder (ADHD). METHODS: The literatures were searched using 15 databases, including MEDLINE, AMED, CINAHL, EMBASE, PsycInfo, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, six Korean medical databases and two Chinese databases without language restritions. Prospective controlled clinical studies of any type of acupuncture therapy for ADHD autistic patients were included. Trials in which acupuncture was part of a complex intervention were also included. All articles were read by two independent reviewers, who extracted data from the articles according to predefined criteria. Risk of bias was assessed using the Cochrane risk of bias tool. RESULTS: Of 114 articles, only three randomized clinical trials (RCTs) met our inclusion criteria. One RCT found that electroacupuncture (EA) plus behavioural treatment was superior to sham EA plus behavioural treatment. Two RCTs reported a significant benefit of acupuncture or auricular acupuncture over conventional drug therapies. CONCLUSIONS: Limited evidence exists for the effectiveness of acupuncture as a symptomatic treatment of ADHD. Given that the risk of bias of the included studies was high, firm conclusions cannot be drawn.

Comparing the effects of distilled Rehmannia glutinosa, Wild Ginseng and Astragali Radix pharmacopuncture with heart rate variability (HRV): a randomized, sham-controlled and double-blind clinical trial.

This study compared the effects of distilled Rehmannia glutinosa, Wild Ginseng and Astragali Radix pharmacopuncture on the autonomic nervous system and heart rate variability. The purpose of the trial was to observe the influence distilled Astragali Radix, Wild Ginseng and Rehmannia glutinosa pharmacopuncture have on the autonomic nervous system. 120 healthy male volunteers were divided into four groups, which consisted of three experimental groups and a control group. This study was a randomized, placebo-controlled, double-blind clinical trial. Volunteers in experimental groups were underwent pharmacopuncture at GB21 (Kyonjong), and volunteers in the control group were injected with normal saline at GB21 (Kyonjong). Heart rate variability was measured seven times: before and after injection, every 5 minutes for 30 minutes. The result was distilled Rehmannia glutinosa, Wild Ginseng and Astragali Radix pharmacopuncture in healthy adult males tended to activate the autonomic nervous system, particularly the sympathetic nervous system.
