Background: The aim of this study was to assess the change in radiating leg pain after traffic accidents in patients with and without herniated intervertebral disc (HIVD) and improvement of radiating leg pain after traffic accidents. Methods: This was an retrospective study of 188 patients. Patients who had been admitted to the Hospital of Korean Medicine with the complaint of radiating leg pain after traffic accidents, and who had undergone lumbar spine magnetic resonance imaging to determine the presence or absence of HIVD were observed from April to June 2016. We analyzed sex, age, length of admission, direction (to a single leg or to both legs) and locations, (medial, anterior, lateral or posterior side of the lower limb) of radiating leg pain, presence or absence of HIVD, and number, grade and position of HIVD. The Numeric Rating Scale (NRS) and Oswestry Disability Index (ODI) were used to evaluate the impact of radiating leg pain on patients. Results: Radiating leg pain NRS score decreased significantly in both the HIVD group (from $6.12{\pm}2.39$ to $4.31{\pm}1.87$, p < 0.001) and the no HIVD group (from $5.76{\pm}1.64$ to $3.85{\pm}1.41$, p < 0.001). ODI score also decreased significantly in both groups (HIVD, from $44.67{\pm}17.38$ to $26.83{\pm}13.18$; no HIVD, from $39.24{\pm}15.58$ to $19.69{\pm}12$.; both p < 0.001). Conclusion: There was no significant change in radiating leg pain after traffic accidents in patients with and without HIVD and improvement of radiating leg pain after traffic accidents.

Objectives The present study was designed to analyze the posture pattern of healthy right-handed male and to investigate the effect of Chuna treatment. Methods Twenty healthy right-handed male were selected in this study. Body posture was measured by Body $Style^{(R)}$. After that, subjects received Chuna treatment on lumbar and pelvis area. Finally, the 2nd measurement was carried out. Results In shoulder height, left shoulder was higher than right one. In pelvic height, right iliac crest was higher than left, followed by longer right leg than left. In lower limb angle suggesting valgus or varus knee. In height of scapula inferior angle, right seemed higher than left. After the Chuna treatment, shoulder height, pelvic height, and leg length difference showed significant improvement. Other variables showed improvement but it was not significant. Conclusions These results suggest that right-handed male have some characteristic posture pattern because of their daily life habits, and Chuna treatment can be effective in correcting bad posture.

The dynamic compliance characteristics of a prosthetic foot midgait are very important for natural performance in an amputee's gait and should be in a range that provides natural, stable walking. In this study, finite element analysis (FEA) and classical laminate theory were used to examine the mechanical characteristics of a carbon-epoxy composite laminate prosthetic foot as a function of variation in the lamination composition. From this analysis, an FEM model of a prosthetic keel, made from the composite material, was developed. The lamination composition of the keel was designed for improved stiffness. The prototype product was fabricated using an autoclave. Vertical loading response tests were performed to verify the simulation model. The results of the experiments were similar to those from simulations below the loading level of the gait, suggesting use of the proposed simulation model for prosthetic keel design.

The purpose of this study is to suggest a proper tread of stairs using kinematic factors and moments of the lower-limb joints in the stair decent with the 3 different treads with boimechanical method in ergonomics. 9 subjects (body masses; $59.41{\pm}7.49$, $64.03{\pm}6.65$, $67.26:{\pm}7.58$, heights; $160.50{\pm}6.35$ ages; $31.22{\pm}2.99$; parity; $1.67{\pm}0.71$) participated in three experiments that were divided by physiological symptoms (the early (0-15 weeks), middle (16-27 weeks) and last (18-39 weeks). and they walked at self-selected pace on 4 staircases 3 trials. As extending the pregnancy period, cadence was shorter but cycle time were longer more and more. As extending treads of stair decent during pregnancy, speed, stride lengths and cycle time were increased. As extending the treads of stair decent, hip and ankle moments increased but knee moments decreased in sagittal plane. There were increasing or decreasing of moments by means of treads. These changes may account for relation between the treads of stair and moments in pregnant women. The main changes of pregnant women were joint moments and kinematic factors during pregnancy period because pregnancy makes them physical changes. It is possible that joints have connection with compensation each other to maximize stability and to control gait motion. In conclusion, we suggest that the tread of stair is longer than 26cm tread. and exercise programs to improve muscle activity were necessary where joint moments were small.

Purpose: During Postpartum period many women complain multiple pain, cold hypersensitivity, hot flush, sweating and so on. We call the postpartum disease as San Hu Pung. We studied DITI Characters of women suffering from Postpartum disease. Methods: We studied 74 postpartum women visiting OOhospital from February 2006 to December 2009. The subjects were categorized in two groups, symptom group and no symptom group. We measured the temperatures of abdomen, upper and lower limb and back. We studied the difference of DITI between two groups by Student T-test using SPSS for windows(version 17.0). Results: The general characteristics were not different statistically. Temperatures of abdomen and back of two groups were not different statistically. Temperatures of both LR3 of symptom group were statistically higher than no symptom group. The difference of both PC8 and LU4, both LR3 and ST32 of symptom group were statistically higher than no symptom group. Conclusion: The results suggest that women suffering from Postpartum disease shows high temperatures on hand and foot. It seems that postpartum disease patients tend to have blood deficiency. DITI can be useful to diagnose San Hu Pung. More studies to diagnose San Hu Pung would be needed.

Large soft tissue defect of the ankle and foot can present a difficult reconstructive problem to the surgeon. Local musculocutaneous, local fasciocutaneous or free flap is usually the first choice for providing soft tissue coverage. However, in certain situations, local flaps from the same leg and free flap may not be suitable. These include extensive soft tissue injury, where no suitable recipient vessels can be found, previous local fasciocutaneous flap or free flap failure. In such cases, we have utilized the septocutaneous(fasciocutaneous) branch flap of posterior tibial artery from the opposite healthy limb. We present 5 cases of cross leg flaps, which have been modernized with current understanding of vascular anatomy and current fixation technology. All cross leg flaps were based on the axial blood supply of the fasciocutanous branch of the posterior tibial artery. Cross-clamping with bowel clamp was used to create intermittent periods of ischemia. Adjacent lower extremity joints were exercised during the periods of attachment. The results have been quite encouraging. We conclude that the cross leg flap using septocutaneous flap and cast immobilization can be successfully and expeditiously used to cover defects of the ante and foot.

Background The aim of this study was to investigate the effects of remote ischemic conditioning on ischemia-reperfusion injury in rat muscle flaps histopathologically and biochemically. Methods Thirty albino rats were divided into 5 groups. No procedure was performed in the rats in group 1, and only blood samples were taken. A gracilis muscle flap was elevated in all the other groups. Microclamps were applied to the vascular pedicle for 4 hours in order to achieve tissue ischemia. In group 2, no additional procedure was performed. In groups 3, 4, and 5, the right hind limb was used and 3 cycles of ischemia-reperfusion for 5 minutes each (total, 30 minutes) was applied with a latex tourniquet (remote ischemic conditioning). In group 3, this procedure was performed before flap elevation (remote ischemic preconditoning). In group 4, the procedure was performed 4 hours after flap ischemia (remote ischemic postconditioning). In group 5, the procedure was performed after the flap was elevated, during the muscle flap ischemia episode (remote ischemic perconditioning). Results The histopathological damage score in all remote conditioning ischemia groups was lower than in the ischemic-reperfusion group. The lowest histopathological damage score was observed in group 5 (remote ischemic perconditioning). Conclusions The nitric oxide levels were higher in the blood samples obtained from the remote ischemic perconditioning group. This study showed the effectiveness of remote ischemic conditioning procedures and compared their usefulness for preventing ischemiareperfusion injury in muscle flaps.
