본 연구는 신경계를 자극하는 카페인이 신경전도속도(nerve conduction velocity. NCV)에 미치는 영향에 대해 알아보고자 하였다. 카페인의 종류는 커피를 사용하였다. 커피는 가장 쉽게 접할 수 있고, 많은 현대인들이 좋아하는 기호 식품으로 자리잡고 있다. 커피안에 있는 특수한 성분인 카페인은 카페인은 알칼로이드계 메틸화 화합물의 하나로서 이뇨 촉진, 혈관 확장, 중추신경흥분, 골격근 강화, 기관지 확장 등의 작용이 있다. 카페인 섭취가 신경속도를 향상시켜 반응시간의 감소를 실험한 연구는 미흡한 실정이다. 이에 본 연구는 신경계를 자극하는 카페인이 신경전도속도(nerve conduction velocity. NCV)에 미치는 영향에 대해 알아보고자 하였다. 대조군 및 실험군 개별 집단 내에서의 사전, 사후 신경전도속도(nerve conduction velocity. NCV) 수치를 비교한 결과, 대조군의 경우 두 곳의 측정 구간 모두 통계적으로 유의미한 차이가 나타나지 않았으나, 실험군은 팔꿈치 위 액와 구간에서의 신경전도속도(nerve conduction velocity. NCV)가 카페인 섭취 후 유의미하게 증가한 것으로 나타났다. 카페인을 섭취함으로 인해 신경전도속도(nerve conduction velocity. NCV)가 증가하였고, 이것은 일시적으로 신경전도속도(nerve conduction velocity. NCV)를 증가시킴으로써 운동능력향상, 근력향상, 신경기능향상 등에 대해 도움이 될 것이라고 판단하였다. 본 연구를 통하여 적정량의 카페인섭취는 신경전도속도신경전도속도(nerve conduction velocity. NCV)향상에 대해 도움을 줌으로써 카페인이 말초신경계에 영향력이 있다는 것을 알게 되었다. 이러한 결과를 통해 근기능장애, 신경기능장애 환자의 치료와 진단법 개발에 도움을 줄 것이라 기대하는 바이다.

Background: The medial plantar nerve (MPN) is a distal branch of the posterior tibial nerve, and various methods of nerve conduction study for MPN have been introduced so far. Hemmi et al described a new method (Hemmi's method) for recording medial plantar sensory nerve action potentials (SNAPs), which is considered as a simple and reliable method for measuring medial plantar SNAPs. This study was aimed to establish the normal values for the MPN conduction study among Koreans and to compare the sensitivities of three different methods for MPN conduction study (Hemmi, Oh, and Saeed's method) in detecting evidence of peripheral neuropathy among diabetic patients. Methods: In 27 healthy subjects, MPN conduction study using Hemmi's method was performed and normal values were calculated. In 54 diabetic patients who showed normal routine nerve conduction studies, three different methods for MPN conduction study were performed and diagnostic sensitivity of each method were compared. Results: In normal subjects, the mean medial plantar SNAP amplitude and conduction velocities measured by Hemmi's method were $4.3{\pm}1.0$ uV and $38.3{\pm}6.8$ m/s respectively. Among 54 patients with diabetes who showed normal routine nerve conduction studies, medial plantar SNAP was not obtainable in 28, 31, and 6 patients by Hemmi, Oh and Saeed's method respectively. Conclusions: In terms of the diagnostic sensitivity for detecting diabetic neuropathy, there had been no significant statistical difference between three different methods. Our study suggested that MPN conduction study using Hemmi's method is simple and useful screening test for early diabetic neuropathy, and is comparable with Oh's method.

Purpose: The purpose of this study was to resolve, in an efficient manner, the mechanoreceptor problems of the part far from the paretic upper extremity in stroke patients, as well as to provide clinical basic data of an intervention program for efficient neurodynamic in stroke patients, by developing a rhythmic neurodynamic exercise program and verifying functional changes depending on the increase in the upper extremity nerve conduction velocity. Methods: Samples were extracted from 18 patients with hemiplegia, caused by stroke, and were randomly assigned to either the experimental group I for the general upper extremity neurodynamic (n=9) and the experimental group II for rhythmic upper extremity neurodynamic (n=9). An intervention program was applied ten times per set (three sets one time) and four times a week for two weeks (once a day). As a pre-test, changes in the upper extremity nerve conduction velocity and functions were assessed, and two weeks later, a post-test was conducted to re-measure them in the same manner. Results: The wrist and palm sections of the radial nerve and the wrist and elbow sections of the median nerve, as well as the wrist, lower elbow, upper elbow, and axilla sections of the ulnar nerve had significant differences with respect to the upper extremity nerve conduction velocity between the two groups (p<0.05)(p<0.01), and significant differences were also found in the upper extremity functions (p<0.05). Conclusion: Rhythmic neurodynamic accelerated the nerve conduction velocity more in broader neural sections than the general neurodynamic. In conclusion, rhythmic neurodynamic was proven to be effective for improving the functions of upper extremity.

Isolated posterior antebrachial cutaneous (PABC) neuropathy is rare. A 62 year-old man presented with hypesthesia over the skin region of PABC nerve territory after an injection at the proximal to the lateral epicondyle. Antidromic sensory nerve conduction studies of PABC nerve was not evoked on the affected side. Our case showed that sensory nerve conduction of PABC nerve can be performed without much difficulty and that this test is useful in confirming PABC neuropathy.

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy in clinical practice, with a 0.1% life time risk in the general population. Conventional neurophysiological studies have been useful in the diagnosis of this condition, as have a number of more specialized procedures. Therefore, we evaluated the diagnostic sensitivities of several parameters in nerve conduction technique for CTS patients. We analyzed 100 patients (159 hands) who were diagnosed with CTS clinically and electrophysiolosically. Median motor and sensory nerve conduction velocities (MCV and SCV) with wrist, palm, and finger stimulation were performed in traditional methods. Sensitivities of each test were calculated and compared to normal control data. The sensitivities of existing nerve conduction method were noted in terminal latency on median nerve, 2nd finger-wrist segment, 3rd finger-wrist segment, palm-wrist segment and distoproximal ratio, as 72.96%, 92.45%, 94.34%, 94.97%, and 97.48%, respectively. In the early course of CTS, sensory nerve conductions in the median nerve are more valuable than motor nerve conduction. Sensory nerve conductions are usually affected before motor nerve conductions in CTS. In this study, we detected that slowing of median SCV was the most frequent in the distoproximal ratio.

Neurotoxicity in the workplace may occur with exposure to scores of chemicals. Although large acute outbreaks of the occupational neurological disease are rare, the incidence of occupational neurotoxicity in its subtler aspects is unknown. A working knowledge of both the major occupational neurotoxic solvents and the tools used by cliniical neurologists and neurotoxicologists to evaluate neurotoxicity in working populations is a necessity fur the occupational physician. To investigate the effects of carbon disulfide($CS_2$) on the peripheral nerve system using the nervous conduction study, 105 male workers working in the spinning room of a viscose rayon factory were examined and compared with a sex and age matched, unexposed 105 male controls using t-test analysis. 72.4% of $CS_2$-exposed workers complained of neurological symptoms, and the abnormal cases in nerve conduction study were 48.6%. The abnormal cases of nerve conduction study increased in number according as the age and duration of exposure increased. In this study, asymptomatic workers were confirmed to have subclinical neuropathy by nerve conduction study. Also as there were abnormal cases even in its duration of exposure below 4 years, nerve conduction study turned out to be ways of discovering of early peripheral neuropathy. In nerve conduction study, the amplitude, velocity, F-wave latency and H-reflex of the motor and sensory nerves in both upper and lower extremities were significant different between $CS_2$-exposed workers and the controls. From the pathological viewpoint, both segmental and axonal degenerations were assumed in this study.

Objective: The purpose of the study was to evaluate the effectiveness of treating the carpal tunnel syndrome by using both the Herbal Acupuncture and herbal medicine therapy on five cases. Methods: For the Herbal Acupuncture, Jungseonguhhyul No. 1 and Hwanglyunhaedoktang were used. For the herbal medicine, Dangguihwalhyul-tang was used. The patients were treated once in every two days; the result was evaluated after ten treatments. Patients' conditions were monitored through their testimony, phalen's test, nerve conduction study and electromyography. Results: In all five cases, the patients showed improvement; in four cases, the patients no longer had most of the clinical symptoms. Based on the result of the nerve conduction study, for the four cases in which the patients no longer displayed most of the clinical symptoms, their nerve conduction rate improved; for the remaining one case, the patient's nerve conduction rate deteriorated. Conclusions: The results of this study demonstrate that combining the Herbal Acupuncture and herbal medicine therapy can have noticeable effects in treating the carpal tunnel syndrome; developing more variety of the herbal acupuncture would lead to even better treatment results.

Although various criteria on the diagnosis of diabetic neuropathy are applied from trial to trial, being tailored in concert with its purpose, the utmost evidences of the diagnosis are subjective symptoms and objective signs of neurologic deficit. The application and interpretation of auxiliary electrophysiological test including nerve conduction study (NCS) should be made on the context of clinical pictures. The evaluation of the functions of small, thinly myelinated or unmyelinated nerve fibers has been increasingly stressed recently with the advent of newer techniques, e.g., measurement of intraepidermal fiber density, quantitative sensory testing, and autonomic function test. And the studies with those techniques have shed light to the nature of the evolution of diabetic neuropathy. The practical application of these techniques to the diagnosis of diabetic neuropathy in the individual patients, however, should be made cautiously due to several shortcomings: limited accessibility, wide overlapping zone between norm and abnormality with resultant unsatisfactory sensitivity and specificity, difficulty in performing subsequent tests, unproven quantitative correlation with clinical deficit, and invasiveness of some technique. NCS, as an extension of clinical examination, is still the most reliable electrophysiological test in evaluating neuropathy and gives the invaluable information about the nature of neuropathy, whereas the newer techniques need more refinement of the procedure and interpretation, and the accumulation of large scaled data of application to be considered as established diagnostic tools of peripheral neuropathy.

The determination of peripheral nerve conduction velocity is an important part to electrodiagnosis. Its value as neurophysiologic investigative procedure has been known for many years but normal value of median and ulnar motor nerve was poorly reported in Korea. To evaluate of median and ulnar motor nerve terminal latency, amplitude of CMAP(compound muscle action potential), conduction velocity and F-wave latency for obtain clinically useful reference value. 71 normal volunteers(age, 19-65 years; 142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking II was use for detected terminal latency, amplitude of CMAP, conduction velocity and F-wave latency of median and ulnar motor nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation, independent t-test was used to compare between Rt and Lt side also compare between different in genders. The results are summarized as follows: 1. Median motor nerve terminal latency was right 3.00ms, left 2.99ms and there was no significantly differences between right and left side and genders. 2. Median motor nerve amplitude of CMAP was right 17.26mV, left 1750mV and there was no significantly differences between right and left side and genders. 3. Median motor nerve conduction velocity was right 57.89m/sec, left 58.03m/sec and there was no significantly differences between right and left side and genders. 4.
