The utility and accuracy of intraoperative neurophysiological monitoring (IONM) has evolved greatly following the recent development of new devices for neurophysiological testing and advances in anesthesiology. Until recently, the need for IONM services has been limited to large academic hospitals, but the demand for neurophysiologists with expertise in IONM has grown rapidly across diverse types of hospital. The primary goal of the Korean Society of Intraoperative Neurophysiological Monitoring (KSION) is to promote the development of IONM research groups and to contribute to the improvement of fellowship among members and human health through academic projects. These guidelines are based on extensive literature reviews, recruitment of expert opinions, and consensus among KSION board members. This version of the guidelines was fully approved by the KSION, Korean Association of EMG Electrodiagnostic Medicine, the Korean Society of Clinical Neurophysiology, the Korean Academy of Rehabilitation Medicine, and the Korean Neurological Association.

Transcranial magnetic stimulation (TMS) is a safe and noninvasive tool for investigating the cortical excitability of the human brain and the neurophysiological functions of GABAergic, glutamatergic, and cholinergic neural circuits. Neurophysiological biomarkers based on TMS parameters can provide information on the pathophysiology of dementia, and be used to diagnose Alzheimer's disease and differentiate different types of dementia. This review introduces the basic principles of TMS, TMS devices and stimulating paradigms, several neurophysiological measurements, and the clinical implications of TMS for Alzheimer's disease.

Neurophysiological therapeutic exercise had started 1940-1960 that used for CNS patient's rehabilitation is the world. In America, PNF, Bobath, Brunnstrom technique are reviewed through the NUSTEP and II STEP on 1967. The NUSTEP provide common interest of neurophysiological therapeutic exercise. The II STEP provide new concept of neurophysiological therapeutic exercise from scholar, professor and clinician. New concept include not only using the reflex but also motor learning, motor control and motor behavior. It is including neurobiologic interaction, biomechanics and motor science. Therefore, neurophysiological therapeutic exercise have to change with the purpose of the therapeutic exercise.

감각통합은 이론에서 출발하여 현재 치료사들이 아동의 문제를 찾고 중재하는데 유용한 틀을 제공한다. 이전까지 대부분의 감각통합 연구들은 감각처리 장애아동들이 나타내는 행동을 측정하는 경험적 증거들을 보고하였다. 최근에 감각처리 장애 진단에 대한 객관적 증거 마련을 위해서 신경생리학적 연구 결과가 축적되기 시작하였다. 감각처리 장애에 대한 신경생리학적 근거를 찾는 연구들은 전기피부 활동, 미주신경 톤, 뇌파를 사용하여 감각처리 장애아동과 전형적으로 발달하는 또래 아동들 간 신경생리학적 반응이 다르다는 결과를 보고하였을 뿐만 아니라 감각처리 어려움과 관련한 행동 특징이 신경생리학적 지표에서도 반영됨을 발견하였다. 앞으로 연구에서는 감각통합 치료 효과를 지지하는 신경생리학적 증거도 얻을 수 있을 것이라 기대해 본다.

Since Hans Berger reported the first paper on the human electroencephalogram in 1920s, huge technological advance have made it possible to use a number of electrophysiological approaches to neurological diagnosis in clinical neurology. In majority of the neurology training hospitals they have facilities of electroencephalography(EEG), electromyography(EMG), evoked potentials(EP), polysomnography(PSG), electronystagmography(ENG) and, transcranial doppler(TCD) ete. Clinicials and electrophysiologists should understand the technologic characteristics and general applications of each electrophysiological studies to get useful informations with using them in clinics. It is generally agreed that items of these tests are selected under the clinical examination, the tests are performed by the experts, and the test results are interpretated under the clinical background. Otherwise these tests are sometimes useless and lead clinicians to misunderstand the lesion site, the nature of disease, or the disease course. In this sense the clinical utility of neurophysiological tests could be summerized in the followings. First, the abnormal functioning of the nervous system and its environments can be demonstrated when the history and neurological examinations are equivocal. Second, the presence of clinically unsuspected malfunction in the nervous system can be revealed by those tests. Finally the objective changes can be monitored over time in the patient's status. Also intraoperative monitoring technique becomes one of the important procedures when the major operations in the posterior fossa or in the spinal cord are performed. In 1996, the Korean Society for Clinical Neurophysiology(KSCN) was founded with the hope that it will provide the members with the comfortable place for discussing their clinical and academic experience, exchanging new informations, and learning new techniques of the neurophysiological tests. The KSCN could collaborate with the International Federation of Clinical Neurophysiology(IFCN) to improve the level of the clinical neurophysiologic field in Korea as will as in Asian region.1 In this paper the clinical neurophysiological tests which are commonly used in clinical neurology and which will be delt with and educated by the KSCN in the future will be discussed briefly in order of EEG, EMG, EP, PSG, TCD, ENG, and Intraoperative monitoring.

Hemifacial spasm (HFS) is due to the vascular compression of the facial nerve at its root exit zone (REZ). Microvascular decompression (MVD) of the facial nerve near the REZ is an effective treatment for HFS. In MVD for HFS, intraoperative neurophysiological monitoring (INM) has two purposes. The first purpose is to prevent injury to neural structures such as the vestibulocochlear nerve and facial nerve during MVD surgery, which is possible through INM of brainstem auditory evoked potential and facial nerve electromyography (EMG). The second purpose is the unique feature of MVD for HFS, which is to assess and optimize the effectiveness of the vascular decompression. The purpose is achieved mainly through monitoring of abnormal facial nerve EMG that is called as lateral spread response (LSR) and is also partially possible through Z-L response, facial F-wave, and facial motor evoked potentials. Based on the information regarding INM mentioned above, MVD for HFS can be considered as a more safe and effective treatment.

The neurophysiological study has been widely used in the search of the relation between brain and behavior. The basic techniques for the animal experiments of this kind such as stereotaxic techniques, lesioning methods, the methods of electrical stimulation and confirmation of histological location were simply reviewed. Nevertheless, the importance of complementary neurochemical, neuroanatomical and behavioral studies can not be neglected.

Intraoperative Neurophysiological Monitoring (INM) inspection has a very important role. While preserving the patient's neurological function be sure to safe surgery, neurological examination should thank. Cerebello pontine angle tumor surgery, especially in the nervous system is more important to the meaning of INM. In cochlear nerve, facial nerve, trigeminal nerve, which are intricate brain surgery, doctors are only human eye and brain to the brain that it is virtually impossible to distinguish the nervous system. They receives a lot of help from INM. In this paper, we examined six kinds broadly. First, the methods of spontaneous EMG and Free-running EMG, which can instantly detect a damage inflicted on a nerve during surgery. Second, methods of triggered EMG and direct nerve electrical stimulation, which directly stimulate a nerve using electricity to distinguish between nerves and brain tumors. Third, the method of knowing a more accurate neurologic status by informing neurological surgeons about Free-running EMG wave forms that are segmetalized into four. Fourth, three ways of knowing when a patient will be awaken from intraoperative anesthesia, which happens due to a weak anesthetic. Fifth, a method of understanding the structures of a brain tumor and a facial nerve as five dividend segments. Sixth, comparisons between cases normal facial nerve recovery and occurrence of a facial nerve paralysis during the postoperative course.

Intraoperative Neurophysiological Monitoring (INM) is very useful in monitoring the motorsensory pathway and vascular circulation system during intraspinal, or intracranial neurosurgery. Brainstem Auditory Evoked Potentials (BAEPs) are for detecting the problems along the auditory pathways including, the eighth cranial nerve and brainstem. Motor Evoked Potentials (MEPs) is a useful adjunct to conventional monitoring of Somato-sensory Evoked Potentials (SEPs) during surgery. Visual Evoked Potentials (VEPs) has been regarded as having limited significance for the preservation of visual function during neurosurgical procedures. In this paper, we propose that the most appropriate averaging of the number of inspections in the inspection of each used in the operative field, is good and efficient, functionally.

마취는 의식의 차단 역할을 하는 주 마취제와 감각, 운동, 반사의 차단을 하는 부 마취제인 근이완제로 구분된다. 깊은 의식의 차단만으로는 심한 자극에 대한 반응을 막을 수 없고, 다량의 진통제만으로는 무의식을 보장할 수 없다. 그러므로 마취는 동시에 두 가지를 모두 만족시켜야 한다. 근 이완제는 흡입 또는 정맥마취제의 투여 용량을 감소시키면서 기관지내 삽입관, 수술 시야 및 수술적 환경(operating conditions)을 향상시킬 수 있으며, 수술 중 기계적 조절 환기(controlled mechanical ventilation) 시 호흡 관리를 위하여 매우 중요하다. 이러한 근이완제는 투여 용량이 과다하면 수술 중 신경 검사가 안 되는 영향을 줄 수 있고, 투여 용량이 부족하게 되면 환자가 수술 중 움직일 수 있어서 근 이완 마취 심도와 수술 중 감시 검사는 밀접한 관계가 있다. 근 이완제를 많이 사용하면, 수술 중 신경생리학적 검사가 원활하게 되지 않는 단점과 수술 이후에 완전히 근 이완효과를 제거하기 어렵다는 단점도 갖고 있다. 수술 중 감시 검사를 하는 수술에서 마취과에서는 어떠한 기준으로 근 이완제를 투여하며 유지하는지에 대하여 국내뿐만 아니라 전 세계적인 동향을 살펴 봄으로써 보다 원활한 수술 중 신경 검사가 되길 바란다.
