The patient with muscle contraction headache usually have one or more specific trigger points. These trigger points have been treated with various treatment modalities including "stretch and spray" and regional infiltration with local anesthetics with or without corticosteroids. I treated 36 patients with muscle contraction headache with regional infiltration of local anesthetics and steroid into trigger points and the results were as follows 1) The diagnosis of muscle contraction headache was possible by confirming specific trigger points by palpation. 2) Patients relieved rapidly from headache by regional infiltration of local anesthetics and steroid into the tender point. 3) Single injection was effective in relieving headache. But the curability of the single injection could not be assessed because of difficulty in follow-up study. 4) Active trigger points could be occasionally inactive, which also made difficult in assessing the effectiveness of the treatment.

The purpose of this study is to show the aerodynamic characteristics and differences in muscle tension dysphonia and adductor spasmodic dysphonia to predict factors which will provide additional information while preparing for the objective examination standard to distinguish the two dysphonias. Forty-eight individuals diagnosed with muscle tension dysphonia and adductor spasmodic dysphonia participated in this study. PAS was used in order to find the aerodynamic characteristics for the two dysphonias. The outcomes of this study show that the airflow variation and glottal resistance of the two groups showed noticeable differences. This study concludes that the aerodynamic characteristics may be used as additional information on diverse evaluations to classify muscle tension dysphonia and adductor spasmodic dysphonia.

Voice is a physical phenomenon, generated by vocal fold and expiratory airflow. Dysphonia should come from abnormal vocal fold and airflow. Occassionally larynx looks normal in show, but it is actually not. There should be undetected structural or functional abnormalities. So when ENT doctors face dysphonia patients who looks normal larynx, should make a diagnosis through close observation. In this review article we present some dysphonia diseases which looks normal larynx. For example vocal fatigue, vocal fold paresis, posterior glottic diastasis, muscle tension dysphonia and psychogenic dysphonia.

This report describes the miniscalpel-acupuncture treatment of a 68-yr-old woman who had abnormal posture and involuntary dystonic movements of the head and neck. She suffered muscle contracture associated symptoms after she fell injured in 2014. Her neck had abnormal posture findings due to muscle tension. The spasms gradually worsened and did not respond to botulinum toxin injections. Involuntary dystonic movements may be due to peripheral post-traumatic cervical dystonia. Outcomes support cervical dystonia may be managed effectively with miniscalpel-acupuncture. Further research is recommended.

연축성 발성장애(spasmodic dysphonia)는 아직까지 그 원인을 정확히 밝혀내지 못하고 있는 만성적인 발성장애로 과거에는 경직성 발성장애(spastic dysphonia)로 불리던 질환이다. 연축성 발성장애는 두 종류 즉, 내전형(adductor)과 외전형(abductor)으로 나누어지며 이중 내전형이 대부분이다. 외전형 연축성 발성장애는 발성도중에 성대가 갑자기 불수의적으로 외전되면서 음성이 중단되므로 원활히 대화하기가 힘든 질환이다. 이러한 질환은 국소적 근긴장이상(fecal dystonia)의 일종이다. 현재까지 연축성 발성장애의 치료법으로 사용되고 있는 것으로는 언어치료, botulium 독소주입술, 편측반회후두신경절 단술, 반회후두신경분쇄술, 상후두신경절단술, 갑상연골성형술, implantable stimulator 등이 있다. 연축성 발성장애 환자에 $Botox^{circledR}$ 주입에 관한 보고는 주로 내전형에 대해서만 보고되고 있으며 외전형에 대하여 보고된 예는 매우 적다.

Objectives Second-generation antipsychotics (SGAs) are frequently used in the treatment of bipolar disorder. However, there is still no consensus on their risk of tardive movement syndromes especially for first-generation antipsychotics (FGAs)-naïve patients. This study aimed to investigate the prevalence and associated factors of SGAs-related tardive dyskinesia and tardive dystonia in patients with bipolar disorder, in a naturalistic out-patient clinical setting. Methods The authors assessed 78 non-elderly patients with bipolar (n = 71) or schizoaffective disorder (n = 7) who received SGAs with a combined use of mood stabilizers for more than three months without previous exposure to FGAs. Multiple direct assessments were performed and hospital records longer than one recent year describing any observed tardive movement symptoms were also reviewed. Results The prevalence rates of tardive dyskinesia and tardive dystonia were 7.7% and 6.4%, respectively. These patients were being treated with ziprasidone, risperidone, olanzapine, quetiapine, or paliperidone at the time of the onset of the movement symptoms. Tardive dyskinesia was mostly observed in the orolingual area, and tardive dystonia was most frequently detected in oromandibular area. A past history of acute dystonia was significantly associated with presence of both tardive movement syndromes. Conclusions Our findings suggest that SGAs-related tardive movement syndromes occur in a substantial portion of bipolar disorder patients. Acute dystonia, a reported risk factor of tardive movement syndromes in the era of FGAs is confirmed as a risk factor of both tardive dyskinesia and tardive dystonia that were induced-by SGAs.

Background and Objectives : Adductor type spasmodic dysphonia (ADSD) is neurogenic disorder and focal laryngeal dystonia, while muscle tension dysphonia (MTD) is caused by functional voice disorder. Both ADSD and MTD may be associated with excessive supraglottic contraction and compensation, resulting in a strained voice quality with spastic voice breaks. The aim of this study was to determine the utility of spectrogram analysis in the differentiation of ADSD from MTD. Materials and Methods : From 2015 through 2017, 17 patients of ADSD and 20 of MTD, underwent acoustic recording and phonatory function studies, were enrolled. Jitter (frequency perturbation), Shimmer (amplitude perturbation) were obtained using MDVP (Multi-dimensional Voice Program) and GRBAS scale was used for perceptual evaluation. The two speech therapist evaluated a wide band (11,250 Hz) spectrogram by blind test using 4 scales (0-3 point) for four spectral findings, abrupt voice breaks, irregular wide spaced vertical striations, well defined formants and high frequency spectral noise. Results : Jitter, Shimmer and GRBAS were not found different between two groups with no significant correlation (p>0.05). Abrupt voice breaks and irregular wide spaced vertical striations of ADSD were significantly higher than those of MTD with strong correlation (p<0.01). High frequency spectral noise of MTD were higher than those of ADSD with strong correlation (p<0.01). Well defined formants were not found different between two groups. Conclusion : The wide band spectrograms provided visual perceptual information can differentiate ADSD from MTD. Spectrogram analysis is a useful diagnostic tool for differentiating ADSD from MTD where perceptual analysis and clinical evaluation alone are insufficient.

Voice disorder is classified into three categories, structural, neurogenic and functional dysphonia. Neurogenic dysphonia refers to a disruption in the nerves controlling the larynx. Common examples of this include complete or partial vocal cord paralysis, spasmodic dysphonia. Also it occurs as part of an underlying neurologic condition such as Parkinson's disease, myasthenia gravis, Lou Gehrig's disease or disorder of the central nervous system that causes involuntary movement of the vocal folds during voice production. Functional dysphonia is a voice disorder in the absence of structual or neurogenic laryngeal characteristics. A near consensus exist that Muscle tension dysphonia (MTD) is functional voice disorder wherein hyperfunctional laryngeal muscle activity whereas Spasmodic dysphonia (SD) is neurogenic, action-induced focal laryngeal dystonia including several subtype. Both Adductor type spasmodic dysphonia (AdSD) and MTD may be associated with excessive supraglottic contraction and compensation, resulting in a strained voice quality with spastic voice breaks. It makes these two disorders extremely difficult to differentiate based on clinical interpretation alone. Because treatment for AdSD and MTD are quite different, correct diagnosis is important. Clinician should be aware of the specific vocal characteristics of each disease to improve therapeutic outcome.
