  • The purpose of this study was to analyze the effects of three different pelvic tilts on sit-to-stand ativities and to suggest a new therapeutic approach for movement reeducation in patients who have difficulty with sit-to-stand activities. The three different pelvic tilts were: (1) comfortable pelvic tilt sit-to-stand (CPT STS), (2) posterior pelvic tilt sit-to-stand (PPT STS) and (3) anterior pelvic tilt sit-to-stand (APT STS). To analyze the kinematic component of STS, a motion analysis system (Zebris) was applied to the ankle, knee, hip joint, and thigh-off area. Also, to determine the onset time of muscle contraction, surface electrodes were placed to the rectus femoris muscle (RF), the vastus lateralis muscle (VL), the biceps femoris muscle (BF), the tibialis anterior muscle (TA), the gastrocnemius muscle (GCM), and the soleus muscle (SOL). One-way repeated ANOVA was used for the statistical analysis. First, significant differences were found in kinematic variables for the hip, knee, ankle joint, and thigh-off among the three activities. Second, there was significant difference in muscle activation pattern in TA. VL. and BF among three activities. In conclusion, the findings of this study suggest the following evaluative and therapeutic approach for STS activity: (1) Changes in knee and ankle joints should be prioritized and recruitment order differences in VL and RF can be generated to accomplish abnormal STS activity. (2) APT STS can be introduced for movement efficiency and functional advantage when abnormal STS is treated.

  • Calcific myonecrosis is a rare condition in which hypoperfusion due to compartment syndrome causes soft tissue and muscle to become calcified. As calcific myonecrosis gradually deteriorates, secretions steadily accumulate inside the affected area, forming a cavity that is vulnerable to infection. Most such cases progress to chronic wounds that are unlikely to heal spontaneously. After removing the calcified tissue, the wound can be treated by primary closure, flap coverage, or a skin graft. In this case, a 72-year-old man had extensive calcific myonecrosis on his left lower leg, and experienced swelling and increasing tenderness. After removing the muscle calcification, we combined two anterolateral thigh free flaps, which were harvested from the patient's right and left thigh, respectively, to reconstruct the wound with a dead-space filler and skin-defect cover at the same time. The patient recovered without revision surgery or major complications.

  • Purpose: The latissimus dorsi flap and the serratus anterior flap have been used as combined flaps to reconstruct extensive defects. Because these two muscles are usually supplied by the subscapular-thoracodorsal vessels, the two flaps can be based on vascular pedicle that is long and anatomically reliable. In this case, we reported that serratus anterior possessed an anomalous arterial supply totally independent from the subscapular pedicle while raising combined latissimus dorsi and serratus anterior flap. Methods: A 35-year-old male with extensive soft tissue defect in the left perineum and thigh visited. Muscle defects of the medial thigh were observed, and femoral nerve and vessels were exposed. Combined latissimus dorsi and serratus anterior free flap was raised to reconstruct defect. On raising flaps, artery supplying the serratus anterior muscle originated from the axillary artery directly, was lying on the undersurface of the serratus anterior muscle. Results: Because two flap pedicles had no communication and latissimus dorsi muscle was large enough to cover soft tissue defect, we transferred only latissimus dorsi free flap with 1 : 3 meshed skin graft. Patient had limb salvage and satisfactory functional outcome. Conclusion: There are many variations of arterial pedicles of flaps. However, most of these variations remain within known anatomical consistence, thus is an indicator in planning the dissection of the vessels. According to documents, arterial pedicle to the serratus muscle not originated from the thoracodorsal artery is rarely reported, and in most of these cases, the arteries are originated from the subscapular artery. Thus pedicle directly originated from the axillary artery to serratus muscle is a very rare variation in its vascular anatomy.

  • Objectives : This study was performed to analyse single dose toxicity of Sweet Bee Venom(Sweet BV) extracted from the bee venom in Beagle dogs. Methods : All experiments were conducted under the regulations of Good Laboratory Practice (GLP) at Biotoxtech Company, a non-clinical study authorized institution. Male and female Beagle dogs of 5-6 months old were chosen for the pilot study of single dose toxicity of Sweet BV which was administered at the level of 9.0 mg/kg body weight which is 1300 times higher than the clinical application dosage as the high dosage, followed by 3.0 and 1.0 mg/kg as midium and low dosage, respectively. Equal amount of excipient(normal saline) to the Sweet BV experiment groups was administered as the control group. Results : 1. No mortality was witnessed in all of the experiment groups. 2. Hyperemia and movement disorder were observed around the area of administration in all the experiment groups, and higher occurrence in the higher dosage treatment. 3. For weight measurement, Neither male nor female groups showed significant changes. 4. To verify abnormalities of organs and tissues, thigh muscle which treated with Sweet BV, brain, liver, lung, kidney, and spinal cords were removed and histologocal observation using H-E staining was conducted. In the histologocal observation of thigh muscle, cell infiltration, inflammation, degeneration, necrosis of muscle fiber, and fibrosis were found in both thigh tissue. And the changes depend on the dose of Sweet BV. But the other organs did not showed in any abnormality. 5. The maximum dose of Sweet BV in Beagle dogs were over 9 mg/kg in this study. Conclusions : The above findings of this study suggest that Sweet BV is a relatively safe treatment medium. Further studies on the toxicity of Sweet BV should be conducted to yield more concrete evidences.

  • In this study, we investigated relationship of muscular activity in thigh muscle and knee joint angle from bicycle exercise. The EMG signals of 16 persons were measured from rectus femoris and vastus lateralis muscles. The experiment was performed in 5 steps according to saddle distance and 60RPM/200W loads were applied for 1 minute at each step. EMG activation of rectus femoris and vastus lateralis muscles and knee joint angle were recorded using surface EMG and motion analysis system, respectively. Experimental results of inter relationship between EMG activation of thigh muscles and knee joint angle showed high correlation from Step 1. The unified EMG activation of two muscles and knee joint angle showed negative correlation(-0.97).

  • Objective: In this study, we compared the key indices of isokinetic tests for knee joint extension and flexion according to the presence or absence of pain in elite athletes with past knee and thigh injuries. Design: Crossed-sectional study Methods: This study was conducted on 33 elite athletes. The elite athletes who participated in this study were divided into a group with pain and a group without pain due to past knee and thigh injuries. The subjects in each group performed an isokinetic muscle strength test for knee joint extension and flexion. After the isokinetic muscle strength test, the main indices of the isokinetic test were compared between the pain group and the non-pain group. Results: In the comparison of the pain group and the non-pain group for 60°/s knee flexion and extension in elite athletes, there was a significant difference only in the torque max average/kg for knee extension. However, there was no statistically significant difference in all other variables. The comparison of the pain group and the non-pain group for 240°/s also showed a significant difference in the torque max average/kg for knee extension, and there was no statistically significant difference in all other variables. Conclusions: In subjects who have experienced previous knee or thigh injuries and have mild pain during strong isokinetic strength tests, torque average/kg is affected, but other strength variables are not affected. Therefore, it would be good to consider this aspect and use it as a basis for testing and training elite athletes.

  • The purpose of this study was to measure and compare the skin temperature over the exercised muscle and corresponding non-exercised muscle after unilateral isokinetic exercise using digital thermography. Thirty-two young healthy volunteers with no history of knee injury were tested. After isokinetic exercise at 60 degree per second angular velocity using the right leg in a climatic chamber at ambient temperature of $23-26^{\circ}C$, skin temperature of the anterior thigh was tested. After exercise, the skin temperature of both the right and left leg had fallen significantly. The skin temperature of the exercised leg fell less than that of the non-exercised leg. The fall in skin temperature after work was not due to increased evaporative cooling, but was the result of segmental vasoconstriction probably caused reflexly in the spinal cord by non-thermal afferents from exercising muscle or moving tissues. The effect of thermoregulatory vasodilation was reduced by reflex vasoconstriction caused by non-thermal factors such as catecholamine.

  • The aim of this study is to investigate the combined effect of acupotomy, selective cryolysis and herbal medicine therapy for treating regional fat accumulation of thigh. Twenty-four patients were selected for the study. A session of selective cryolysis and acupotomy treatments were performed on both thighs once a week, for four weeks, with administration of herbal medicine. Thigh circumference, weight, body mass index (BMI), skeletal muscle mass, and body fat rate were measured before and after the procedure. Statistical significance (P<0.05) was determined using the paired t-test. After treatments, thigh circumference was significantly reduced by $3.57{\pm}1.41cm$ in 4 weeks (P<0.001). Weight, BMI, skeletal muscle mass, and body fat rate too were significantly reduced (P<0.001). Of the 24 patients, 1 reported an adverse event of frostbite. We assume this combined therapy can be useful when dealing with localized fat accumulation. Long-term evaluation and further studies are required to identify the specific effect size.
