Objectives : The purpose of this study is to establish a Korean medical perspective on the human body through understanding of the meridians according to the distribution of the three yin and three yang (삼음삼양) and the opening, closing and pivot (관합추) as defined in ≪Huangdi's Internal Classic≫. Methods : A total of 8 medical databases including KISS, Earticle, DBpia, RISS, OASIS, KMbase, and ScienceON were used to search studies published through July 2021, and literature was included without limitations on the publication period. The search terms were "(meridian OR acupoint OR meridian sinew) AND position" OR "Gwan-Hap-Chu" OR "Gae-Hap-Chu" OR "three yin and three yang". Two researchers independently made choices among the searched literature based on the preplanned selection/exclusion criteria. The search terms were"(meridian OR acupoint OR meridian sinew) AND position" OR "Gwan-Hap-Chu" OR "Gae-Hap-Chu" OR "three yin and three yang". Results : Of the 36 obtained from the survey, 19 (53%) followed the definitions of "internal diameter" for "three yin and three yang" and "the opening, closing and pivot," but 6 (about 16%) took a neutral position and 10 (22%) avoided mentioning. Therefore, it was judged that research was needed to end the debate on the distribution of 'three yin and three yang' and 'the opening, closing and pivot'. In order to apply the definition of ≪Huangdi's Internal Classic≫ on 'distribution of the three-yin and three-yang' and 'the opening, closing and pivot' to the upper limb and lower limb as well as the torso of the human body, this author proposed a human body model with both upper limb and lower limb attached, inspired by the posture of the fetus in the developmental stage. Conclusions : In this study, using a new human body model, it was revealed that the distribution of the three yin and three yang and the opening, closing and pivot' as defined in the ≪Huangdi's Internal Classic≫ can be applied not only to the torso of the human body, but also to the upper limb and lower limb. Based on the understanding of meridians, the selection of meridians in the clinical acupuncture should be made accurately, and continuous interest and research on this are expected.

Purpose: The purpose of this study was to investigate whether ipsilateral shoulder pain affects the sensorimotor function of the same side shoulder in patients with stroke. Methods: Thirty stroke patients, who were divided into the ipsilateral shoulder pain group (n=15) and the ipsilateral shoulder non-pain group (n=15). Subjects were evaluated on performance of a tracking task, joint reposition test and 9-Hole pegboard test for sensorimotor functions, and Fugl-Meyer test and Motricity Index for functional ability of the contralateral side. Results: In comparison of the two groups, significant differences in performance on functional ability, including the Fugl-Meyer test(both upper and lower limb) and Motricity Index(only lower limb) were observed (p<0.05). With regard to sensorimotor functions, the ipsilateral shoulder pain group were observed significantly poor scores on the Accuracy Index, joint reposition score and 9-Hole pegboard test, when compared with the ipsilateral shoulder non-pain group (p<0.05). Conclusion: We found that ipsilateral shoulder pain could impede accurate performance of a movement and result in deteriorated proprioception of the ipsilateral shoulder. Therefore, careful evaluation and appropriate therapeutic intervention are essential for stroke patients who suffer from ipsilateral shoulder pain.

The purpose of this study was to examine the effects of hemispheric damage in body composition of male adults with stroke experiences. The Fourth and Fifth Korea National Health and Nutrition Examination Surveys (KNHANES) with body composition results obtained from the DXA (dual-energy X-ray absorptiometry) assessments were used for this study. Survey data of 18 post-stroke men and 28 healthy controls were obtained. Both the lean and fat masses of the upper and lower limbs were utilized to compare for the compositions between the limbs in post-stroke subjects. In addition, the effect of exercise habit was also observed for the influence of physical activity in body composition. Mixed results in left and right limb compositions were shown between the groups. When the subjects were further divided based on walking days per week, sedentary (walk ${\leq}2d/wk$) post-stroke group showed significantly greater fat mass and less lean mass than the physically active people (walk ${\geq}3d/wk$). In comparison to the healthy sedentary and physically active controls, two post-stroke groups showed greater variations. The results indicate that physical activity maintains or improve the quality of both the upper and lower limb composition in patients with post-stroke men.

Objective: Electrical stimulation is an assistive technology used to aid the recovery of upper limb use after stroke. The purpose of this systematic review was to determine the effects of electrical stimulation on upper extremity function in individuals with hemiparetic stroke and to develop an evidence base that supports the use of electrical stimulation for upper limb recovery after stroke. Design: A systematic review based on randomized controlled trials (RCTs). Methods: Studies published before April 20 2021 were collected for this review by searching PubMed, four other databases, and RCTs that reported the effects of electrical stimulation on upper extremity function in individuals with the characteristic stroke type. Information on the following parameters was extracted from each study: surname of first author, published year, country, participants, intervention, intervention's intensity, comparison, outcomes, additional therapy, and summary of results. This review also evaluated the bias within each study, including any selection bias, performance bias, detection bias, attrition bias, and reporting bias. Results: This review included five RCTs, and 208 stroke patients were included in the analysis. Stroke patients who underwent electrical stimulation showed significantly improved grip and pinch strengths, wrist range of motion, and basic daily living compared to those in the control group; however, there was no improvement in upper extremity function. Of the selected papers, 60% showed a "high risk" of performance bias, and 20% showed a "high risk" of detection bias. Conclusions: The results of this systematic review suggest that electrical stimulation provides some benefits to stroke patients, such as improved hand strength and range of motion. However, future studies are needed to provide clinical evidence of the effects of electrical stimulation on upper extremity function in stroke patients.

Despite the public health importance of injury and poisoning in terms of its high mortality and incidence, epidemiologic information to be utilized are scarce in Korea. This study was carried out in 1990 on a representative sample population (about 55,000 persons) along with the 6th National Tuberculosis Prevalence Survey in order to estimate the magnitude of injury and poisoning occurrence and to identify its epidemiologic characteristics which can be aided for establishing preventive strategy. Pre-tested and structured Questionnaire was used by trained interviewer to collect data including general information of the person, various information on the injury and poisoning during the past one year such as time and place of its occurrence, its nature and external causes, type of medical institute attended, duration of treatment and outcome of the accident occured. In analysis of the data collected incidence rates per 1000 persons by sex, age group and its nature as well as external causes, and relative frequencies were calculated. The result obtained are as followings; 1. The incidence rate per 1000 was 30 for both sexes, 39 for male and 22 for female, male being 1.8 times more frequent than female. Age adjusted incidences were not much different from the crude rates. Age group specific rate curve showed bimodal shape in both sexes, small peaks in preschool children and higher peaks in older ages. The incidence rate per 1000 people by area was highest in Jeon-bug province (57/1000) and the lowest in Daegu city(11/1000). 2. The place where the injuries occured were road in 46%, within the boundary of house in 25%, and working place in 12% The injuries and poisoning had occured more frequently during the months from March to August of the year than other months. 3. The relatively frequent injuries by its nature were contusion with intact skin surface (19%), fracture of upper limb (13%), open wound of head, neck and trunk (12%) and fracture of lower limb (11%) among males; contusion with intact skin surface (28%), sprains and strains of joints and adjacent muscle (14%), fracture of upper limb (10%) and fracture of lower limb (9%) among females. Higher incidence rate among males than females were fracture of skull (4.5 times), open wound and fractures of limbs ($2{\sim}3$ times). Age specific rate of injuries and poisoning by its nature showed increasing pattern by age in fractures of upper and lower limbs and sprains & strains of joints whereas the age group of 30's showed highest incidence in open wounds of upper limb. Fractures of radius and ulna in upper limb, fractures of tibia & fibula and ankle in lower limb were most frequent among fractures of upper and lower limbs. The frequent injuries among sprains and strains of joints and adjacent muscles were that of ankle, foot and back, and among open wound were that of head and fingers. 4. Relative frequency of injuries and poisoning by external causes showed following order : other accidents (25%), accidental falls (23%), motor vehicle accident (22%) and other road vehicle accident (14%) among males and accidental falls (37%), motor vehicle accident (24%) and other accident (18%) among females. The external causes revealing higher incidences among males than females, were other road vehicle accident (4.8 times), vehicle accident not elsewhere classifiable (4.4 times), accidental poisoning (4.4 times), accidents due to natural and environmental factors (2.8 times), and sucide & self-inflicted injuries (2.8 times). Age specific incidence by external causes for frequent injuries showed that incidence of other accident steadily increased from 10's till age 50's; motor vehicle traffic accident increased from age 20's and dropped after age 60's; on the other hand accidental fall increased strikingly by age. The most frequent external causes among motor vehicle traffic accidents was motor vehicle traffic accident involving collision with pedstrain (69%), pedal cycle accident (30%) and other road vehicle accident (71%) among other road vehicle accidents; falls on same level from slipping, tripping or standing (44%) and other falls from one level to another among accidental falls; accidents caused by machinary (32%) for male and striking against or struck accidentally by objects or person for female among other accidents. 5. Seventy nine percent of the injuries and poisonings were treated in general hospital or hospital/clinic. The duration of treatment ranged from a few days to 123 weeks; the majority(52%) took under 2 weeks, 36% for $3{\sim}8$ weeks and 4% over 21 weeks. 6. The accident resulted in full recovery of normal healthy state in 62%, residual functional defects in 21% and on process of treatment in 16%.

This study aimed to evaluate the effectiveness of imagery training on upper limb function and activities of daily living in subacute stroke patients. This study included 16 voluntary participants with subacute stroke. Subjects were randomly assigned to either experimental or control group, with 8 in each group. Imagery training group performed imagery training during 30 minutes and then task-oriented training 30 minutes a day, 5 times a week for 4 weeks. Control group performed task-oriented training during 30 minutes during a day, 5 times a week for 4 weeks. Assessments were made using the Wolf Motor Function Test (WMFT) and Fugl-Meyer motor function assessment (FMA) to evaluate the changes of upper function. And modified Barthel Index (MBI) was measured to evaluate the activities of daily living. The results showed that imagery training group was more significant increase than control group in WMFT, FMA, and MBI (p<.05). Small to huge effect sizes of 1.59, 2.02, 0.37 were observed for WMFT, FMA, and MBI, respectively. This study indicated that imagery training may be helpful in improving the upper limb function and activities of daily living for subacute stroke patients, and support the clinical feasibility of the imagery training.

Benign monomelic amyotrophy(BMA) is an uncommon cause of progressive mildly disabling atrophy and weakness of a limb. It predominantly affects the distal upper limb of young men. I present two men with BMA of the lower extremities. Although the disorder seemed clinically confined to a arm or leg, I confirmed by electromyography evidence of denervation in the other extremities. I reviewed the literatures and discuss the differential diagnosis. BMA is a diagnosis of exclusion that requires consideration in men with unilateral arm or leg atrophy and weakness.

This study identifies the optimal tube voltages depending on the changes in the patient's body type for limb tests using a digital radiography (DR) system. For the upper-limp test, the dose area product (DAP) was fixed at $5.06dGy{\ast} cm^2$, and for the lower-limb test, the DAP was fixed at $5.04dGy{\ast} cm^2$. Afterwards, the tube voltage was changed to four different stages and the images were taken three times at each stage. The thickness of the limbs was increased by 10 mm to 30 mm to change in the patient's body type. For a quantitative evaluation, Image J was used to calculate the contrast to noise ratio (CNR) and signal to noise ratio (SNR) among the four groups, according to the tube voltage. For statistical testing, the statistically significant differences were analyzed through the Kruskal-Wallis test at a 95% confidence level. For the qualitative analysis of the images, the pre-determined items were evaluated based on a 5-point Likert scale. In both upper-limb and lower-limb tests, the more the tube voltage increased, the more the CNR and SNR of the images decreased. The test on the changes depending on the patient's body shape showed that the more the thickness increased, the more the CNR and SNR decreased. In the qualitative evaluation on the upper limbs, the more the tube voltage increased, the more score increased to 4.6 at the maximum of 55kV and 3.6 at 40kV, respectively. The mean score for the lower limbs was 4.4, regardless of the tube voltage. The more either the upper or lower limbs got thicker, the more the score generally decreased. The score of the upper limps sharply dropped at 40kV, whereas that of the lower limps sharply dropped at 50kV. For patients with a standard thickness, the optimized images can be obtained when taken at 45kV for the upper limbs, and at 50kV for the lower limbs. However, when the thickness of the patient's limbs increases, it is best to set the tube voltage at 50 kV for the upper limbs and at 55 kV for the lower limbs.
