The purpose of this study was to investigate the relationship of the head posture with the tone and stiffness of the cervical extensor muscles. Eighty adults in their twenties were chosen as subjects, and the tone and stiffness of the cervical extensor muscles were measured, with their usual head posture in the sagittal plane. For the measured head posture, the craniovertebral angle (CVA), craniorotation angle (CRA), and forward shoulder angle (FSA) were analyzed using Image J. It was observed that the tone and stiffness of the upper trapezius muscle increased significantly with a decrease in the CVA as well as with an increase in the CRA (p < 0.05). As a result of further classification into the normal and forward head postures based on the CVA of the subjects, the forward head posture was characterized by a significant increase in the tone and stiffness of the upper trapezius muscle (p<.05). The results of this study are expected to be used as basic data for the evaluation of the forward head posture and posture education in clinical practice.

In this study, we wanted to know the change in the craniovertebral angle before and after stretching and muscle tone according to rest time immediately after stretching. 57 students in their 20s and 30s were targeted, and the craniovertebral angle was compared before and after stretching. Static manual stretching was applied for stretching, and after 30 seconds, it was repeated three times with a break time of 10 seconds, and before stretching, immediately after, two minutes after, and five minutes after stretching were measured using muscle tone measuring equipment. As a result, there was no significant difference in craniovertebral angle before and after stretching, and the change in muscle tone according to the rest time after stretching was more significant after 5 minutes than before stretching. It is more effective to take five minutes to rest after stretching, reduce muscle tone than working immediately after stretching.

The purpose of this study was to identify differences in the muscle tone and stiffness of neck muscles according to levels of cardiopulmonary resuscitation (CPR) skill. The subjects were 30 female students in their 20s who were divided into a skilled group (n=15) and an unskilled group (n=15). According to the results, the skilled group showed statistically significant decreases in the stiffness of the lower cervical muscle and the muscle tone of the upper trapezius on the above hand side of hand grips after CPR (p<.05). The unskilled group exhibited a statistically significant difference in both the muscle tone and stiffness of the upper trapezius muscle on both sides after CPR (p<.05). However, no statistically significant differences were found between the two groups. In addition, the non-skilled group showed statistically significant lower values than the skilled group in the mean compression rate, total number of compressions, accuracy of chest compression, and accuracy of chest relaxation (p<.05). This study confirmed that CPR has a myophysiological effect on the neck muscles of those who perform CPR. However, it found that no differences result from individual CPR skill levels that are an important element for the accuracy of CPR.

Oromandibular dystonia is a focal neurological movement disorder characterized by involuntary sustained and often painful muscle contraction, usually producing repetitive movements or abnormal positions of the mouth, jaw and.or tongue. Patients suffering from oromandibular dystonia often experience difficulties in chewing, swallowing and speaking, resulting from the impairment of mandibular movements. At present there is no etiologic treatment for oromandibular dystonia, because the pathophysiology of primary and focal dystonia is still incompletely understood. Many treatments such as medication, behavioral therapy, surgery are suggested to decrease the involuntary movements. But these success rates are relatively low and they have a lot of complications. many studies suggested that chemodenervation with botulinum toxin is the most effective treatment for oromandibular dystonia. We reported the 2 cases which were treated oromandibular dystonia with botulinum toxin and reviewed the orofacial movement disorders(especially oromandibular dystonia) and botulinum toxin treatment for oromanfibular dystonia.

본 연구는 전방머리자세 대학생을 대상으로 목뼈안정화운동이 머리뼈척추각, 깊은목굽힘근 지구력 및 뒤통수밑근 근긴장도의 변화를 알아보고자 하였다. 이 연구 결과 CSEG에서 CVA, DNFET에서 유의하게 증가하였으며 뒤통수근 근긴장도에서는 경직도에서만 유의하게 감소하였다. 목뼈 안정화운동은 목뼈의 중립자세를 유지하면서 깊은목 굽힘근 활성화되고 근지구력이 향상되었으며, 턱을 당기는 동작으로 튀통수근의 경직이 감소한 것으로 생각된다. 또한 지구력 증가시키고 근 긴장도에 감소는 통증을 조절함에 있어서도 도움이 될 것이다. 따라서 목뼈안정화운동은 깊은목굽힘근과 뒤통수근의 개선을 위한 중재방법임을 확인할 수 있었으며, 전방머리자세 예방하기 위해 필요할 것으로 생각된다.

두통은 인간을 괴롭히는 제일 흔한 통증 중의 하나로 평생 살아가면서 한번쯤 경험해 보지 못한 사람은 아무도 없을 것이다. 근긴장성 두통은 가정, 직장 등 우리 생활속의 스트레스로 인해 생기는 두통이다. 무엇보다도 일상생활의 즐거움을 찾아 스트레스를 푸는 것이 가장 중요하다.

Object : This study was performed in order to examine the correlation between acute neuroleptic-induced dystonic reactions and serum iron level. Method : Serum iron levels were measured in psychiatric inpatients who had developed acute neuroleptic-induced dystonia(N=41) and in control patients with no history of acute dystonic reactions(N=37). Serum iron levels were compared in acute dystonic inpatients before starting treatment with neuroleptics and after acute dystonic reaction. Results : The patients exhibiting acute dystonic reactions had significantly lower serum iron levels than the patients without acute dystonic reactions. Conclusion : This result supports an association between low serum iron and the occurrence of neuroleptic-induced acute dystonic reactions.

The purpose of this study was to provide basic data on the thera-tainment intervention method and to relieve dysmenorrhea by identifying the effects of silver spike point therapy on menstrual pain, muscle tone, and muscle stiffness among 30 women in their 20s. The subjects had a regular menstrual cycle, had a visual analog scale score of more than 4 for dysmenorrhea pain, and did not have any gynecological disease. SSP therapy was applied for 20 minutes on San-Yin-Jiao on the first day of their menstrual cycles. Muscle tone and stiffness were measured with Myoton before treatment, immediately after treatment, and 3 hours after treatment. SPSS version 19 was used to analyze the collected data. Using Friedman test, muscle tone and stiffness were measured before treatment, immediately after treatment, and 3 hours after treatment. The results indicate that after treatment dysmenorrhea pain steadily decreased and muscle tension and stiffness decreased significantly. This shows that using SSP therapy is effective on reducing primary dysmenorrhea and improving women's health care. This shows that using SSP therapy is effective at reducing primary dysmenorrhea and improving women's health care.

Objective: The purpose of this paper is to study the possible differences in clinical and polysomnographic findings, depending on the presence or absence of subjective complaints of abnormal sleep behavior, in patients with RWA on polysomnography. Method: We reviewed patient records and polysomnographic data of patients referred to the Sleep Laboratory at Seoul National University Hospital from June 1996 through October 2002. We defined the manifest RBD group (n=32) as patients having both complaints of abnormal sleep behavior and RWA on polysomnography. The latent RBD group (n=20) consisted of patients who exhibited RWA on polysomnography but did not complain of abnormal sleep behavior. The clinical characteristics and polysomnographic findings between the two groups were compared and analyzed. Results: Fifty-two subjects had RWA, as detected by polysomnography (42 males and 10 females, mean age of $55.1{\pm}19.1\;years$). Subjects in the manifest RBD group were significantly older than those in the latent RBD group ($61.59{\pm}13.5$ vs. $44.70{\pm}2.76\;years$, independent t-test, p<0.01). More subjects in the manifest RBD group exhibited abnormal REM behavior on polysomnography than did subjects in the latent RBD group (81.3 vs. 50.0%, Fisher's exact test, p<0.05). No significant differences between the groups were found in the prevalence of brain disorders and primary sleep disorders, gender proportion, and sleep architecture. Conclusion: No difference in sleep architecture was found between the manifest and the latent RBD groups. Only age and the presence of abnormal sleep behavior on polysomnography differentiated the two groups. We suggest that RWA on polysomnography without complaints of abnormal sleep behavior may be early manifestation of manifest RBD. Attention to RWA on polysomnography is necessary to help prevent full-blown RBD from developing.
