Clinical conditions causing the lower leg injury and pain in athletes include acute injuries which are acute compartment syndrome, acute strain injury, contusion, muscle cramps, and chronic injuries which are chronic exertional compartment syndrome, achilles tendinitis, shin splints and stress fractures. Most injuries occur during running, jumping and playing soccer. Many of these conditions relate to overuse, increased strength, training errors and environment. It is necessary to know the cause of injuries and treatment methods to prevent the sports related lower leg injuries.

The gracilis muscle is well suited to small and medium-sized soft tissue defects that cannot be adequately handled by simple rotational flaps and it will conform well to irregular contours, can be split longitudinally at both ends to allow cavities and awkwardly shaped spaces and can be transferred in part or in whole. The gracilis muscle used as a free muscle or musculocutaneous flap is small with a long, narrow contour and its vascular pedicle is a terminal branch of the medial femoral circumflex artery and vein. The aims of soft tissue reconstruction are to cover soft tissue defects, to clear up infection and to prepare for further surgical procedures. Authors have performed 12 gracilis muscle flaps in the lower extremities at Chonbuk National University Hospital from June 1994 through March 1998. The results were as follows. 1. 11 cases of 12(91.7%) were sustained from the crushing injury and secondary complications from the traffic accident. 2. The microsurgical anastomosis of one artery and two veins have performed in 6 cases(50%) of 12 and 11(91.7%) cases of 12 were successful at the third postoperative week and in the final result. 3. Gracilis muscle flap is the infetion-resistant and aesthetically acceptable performed in the lower leg 1/3 and the foot.

When the old schwannoma has the degenerative changes, it is named as the ancient schwannoma which was rarely reported. The degenerative changes are perivascular hyalinization, calcification, cystic necrosis, marked decrease of Antoni type A area, and degenerative nuclei and the ancient schwannoma may be misinterpreted as sarcomatous pleomorphisms. We experienced the ancient schwannoma which has massive hemorrhage and hematoma, cystic change, calcification, and marked decrease of Antoni A area in leg on 75 year old male patient, and report it.

The most common anatomic location of calcific tendinitis is the suprasupinatus muscle of the shoulder joint. However, it is known to develop in any joint including the hip, knee. Infarction of skeletal muscle in the distal areas of the limbs due to vascular occlusion is a well recognized systemic condition in patients who have diabetes. The author experienced mass-like lesion combined muscle infarction and calcification within pure semitendinosus tendon without diabetes in posterosuperior area of distal thigh in old age.

In this study, the patterns and characteristics according to gait cycle were analyzed using to EMG signals during walking, and analyzed in the time domain and frequency domain. The experiments was performed divide to level-ground walking and stair walking, and gait cycle was analysis by stance and swing. In the sagittal plane by using the tilt sensor measures the angle of the lower leg, and EMG was measured from the quadriceps and biceps femoris. The tilt of the lower leg was showed the biggest tilt at HS, and showed lowest value at TO. All in walking according to the gait cycle IEMG showed a specific pattern, and is expected useful to determine the gait cycle and kind. In the frequency domain analysis was using STFT on able to frequency analysis according to time, and using the tilt sensor was identify gait cycle. We analyzed also spectrum of the results of the STFT in all gait types, and recognized that stance had broad bandwidth than that of swing. Through this study, it was confirmed the possibility of judgment and analysis of the gait cycle using EMG and the tilt in the sagittal plane of the lower leg. When used it, can improve the quality of life of amputation patients

Changes of the surface area and the volume of limb are important factors for designing clothes and shoes. The limb volume increases slightly in the afternoon in general, because of human activity, as a diurnal variation. Changes are also associated with menstrual cycle, pregnancy, physical exercise and environmental temperature. The most effective method for measuring the surface area of limb is the paper replacement method.

착의행동을 일으키는 전단계의 감각으로서 국소의 냉감각과 체표 각 부위에 있어서의 냉점분포에 대하여 측정을 하였다. 피험자는, 냉점분포 측정에 한국인 여자 대학생 30명, 냉감각측정에는 한국인과 일본인 여자 대학생 8명을 대상으로 하였으며, 환경조건은 실온 $29^{\circ}C{\pm}1^{\circ}C$, 상대습도 $55{\pm}5\%$의 인공기후실로 하였다. 냉자격으로서는 $0^{\circ}C$의 냉각이 사용되었으며, 측정부위는 냉점분포 측정의 경우 체표 20부위, 냉감각 측정의 경우 체표 13부위로 하였고 측정결과는 다음과 같다. (1) 체표면의 냉점분포 밀도는 부위에 따라서 다르며, 체간부와 두부는 냉점분포 밀도가 높고 말단부에 갈수록 그 분포가 낮아졌다. 특히 가장 민감한 부위는 복부였다. 즉 체간부와 두부는 중핵온을 일정하게 보지하므로서 중핵부 체내온의 변화를 방어하기 위한 온도 수용 부위로서의 역할을 하고 있으며, 말초부는 냉점분포가 낮아서 기온에 따라 체표온(외각온)을 광범위하게 변화시키는 사지부의 온도정보입력의 역할을 담당하고 있다고 하겠다. (2) 각 부위에 있어서의 냉감각 순위는 일본인과 한국인 피험자간에 고도의 상관(r=0.93)이 보여져, 양 피험자군간에 차이는 볼 수 없었다. 3) 냉점분포 밀도가 높은 부위인 복부는 냉감각도 가장 민감하였으며, 냉점분포 밀도가 낮은 하퇴부는 냉감각 감수성도 낮게 나타났다. (4) 발바닥과 손바닥은 냉감각을 민감하게 느끼는 부위임에도 불구하고 냉점분포 밀도가 낮게 나타났으며, 이는 특수성이 있는 부위로서 주목되어지는 결과라고 하겠다.
