K. H. KIM, J. H. CHO, and S. C. LEE, The Effect of Taping on Lower Extremity during Jump Landing in Subjects with Functional Ankle Instability. Korean Journal of Sport Biomechanics, Vol. 19, No. 2, pp. 265-272, 2009. Ankle taping is thought that it can be very useful in clinical setting for reducing injury. However, the studies of ankle taping is focused only ankle joint. The purpose of this study was to examine the effect of taping on lower extremity during jump landing in subjects with functional ankle instability. we collected the data from VICON. Joint range of motion for sagittal plane, frontal plane and transverse plane were measured during a jump-landing task. Taping used in this study appeared to restrict ankle motion with altering the knee and hip joint ROM. We found ankle taping had effects of reducing PF, initial contact PF in sagittal plane, while increasing knee flexion, hip flexion, intial contact hip flexion statistically. It decreased ankle inversion, knee valgus, initial contact knee valgus, hip abduction in frontal plane and ankle abduction, hip internal rotation in transverse plane statistically. Ankle taping showed significant change Knee and hip joint ROM with ankle joint ROM.

본 논문에서는 이처럼 중요한 역할을 하는 무릎의 굽힘(flexion)과 폄(extension)에 대하여 측정을 한다. 무릎과 엉덩이를 펴고 골반을 중립상태로 두고 엎드려 무릎을 구부리고 편다. 일반인의 도수 측정 각도는 구부렸을 때 $110^{\circ}$에서 $135^{\circ}$ 사이의 값이 나온다. 여기서 구부렸을 때 고통을 호소하면 무릎 관절 및 근육에 이상이 있는 것이다.

The purpose of this study was to analyze the lower extremities joint moment pattern by two types of service motion in tennis pinpoint and platform stance. Seven skilled high school tennis players participated, and the kinematics were recorded by the Vicon motion analysis system. For the gathering and analysis of the data Workstation, Bodybuilder and polygon were used. joint moments and Ground Reaction Forces for the phases involved were analyzed with the following results. There was a different moment pattern for the lower extremities between the two serve motions. For the platform stance there was only a large dorsal flexion moment but for the pinpoint stance there were other large moments. The flexion and maximum moment of the lower extremities occurred at the point of change from back swing and to the forward swing motion. Therefore, this data provides evidence that there is a high risk of injury at this point.

등산은 누구나 손쉽게 즐기는 국민 스포츠이다. 그러나 생각만큼 간단한 운동은 아니다. 의욕만 앞세우다 자칫 발목이나 무릎 관절에 무리를 줄 수 있으며, 심한 경우 관절이나 관절 주변 조직이 찢어져 수술을 받아야 한다. 관절이나 주변 조직의 부상은 만성 관절염으로 연결되기 쉬우며, 만성 관절염은 노후 인공관절 수술을 받게 되는 가장 큰 원인이 된다. 이번 호에서는 등산으로 인한 근육∙골격계 질환에 대해서는 알아보기로 한다. 이 내용은 동아일보에 게재된 내용을 발췌 정리한 것이다.

Many people in these days participate in running as leisure due to urbanization and socio-economic development. Running is a simple exercise but it can induce its own specific injury pattern because of its repetitive motion. Most runners' injury is caused by chronic overuse syndrome rather than acute trauma. And common accompanying injury in running are anterior knee pain syndrome, Iliotibial band syndrome, stress fracture, plantar fasciitis, Achilles tendinitis, posterior tibial tendon syndrome. Most common area of runners' injury is knee joint. Therefore the authors reviewed the recent literatures and described the classification, etiology, prevention, rehabilitation in this article.

The purpose of the study was to evaluation of the knee lateral collateral ligament (LCL) stability of normal males and females in twenties by using digital telometer. The volunteer subjects agreed the research goal and were 31 normal adults(16 male: $21.1{\pm}1.5$ years, 15 female: $21.2{\pm}1.2$ years) who have not got any illness regarding their knee. X-ray images were taken varus stress on medial femorotibial joint space using by digital telometer, and grade of pain was surveyed. We measured the joint space width (JSW) in the digital radiology. As a result, the JSW of male group were $5.60{\pm}0.76$ mm and JSW of female group were $5.05{\pm}0.55$ mm (p=0.022) on the neutral state of the knee. Based on the result of varus stress on the knee, female group showed much widen than male group but it was not significant difference (p>0.05). When increased varus stress on the knee, all groups were felt pain from 17 daN to 19 daN. The result could be valuable when the varus stress on the LCL by using the digital telometer.

The artificial joint is consisted with the upper structure of tungsten alloy steel and the lower part of polyethelene are applied with load. When this joint is applied with load in this study, the load distribution at the joint and the stress distribution of support hole to install the joint are investigated by finite element analysis. These results can be utilized at obtaining the basic material to have the experiment for the real thing. The crack is initiated as the load is concentrated at the end of corner on the upper structure. This behavior is in accord with a case of tissue damage due to the breakage of artificial joint reported at medical science.

This paper presents a methodology for constructing a surgical simulation environment for the replacement of artificial knee join using CT image data. We provide a user interface of preoperative planning system for performing complex 3-D spatial manipulation and reasoning tasks. Simple manipulation of joystick and mouse has been proved to be both intuitive and accurate for the fitness and the wear expect of joint. The proposed methodology are useful for future virtual medical system where all the components of visualization, automated model generation, and surgical simulation are integrated.

This study was conducted to investigate the effect of the active exercise program using sling on the pain and balance of total knee replacement patients. Subjects were 20 patients who received total knee replacement and are hospitalized, 10 patients in each group were randomly assigned to a group (CPM group) that applied only CPM (Continuous passive motion) and a group (CSG) that combined CPM with a active exercise program using sling. CG was performed CPM 5 days a week, CSG performed CPM 2 days a week and a active exercise program using sling 3 days a week, and each intervention was performed for 40 minutes a day for a total of 4 weeks. Pain was evaluated using VAS (Visual analog scale), and balance was measured using BT4 (Balance training 4) to measure C90 area, trace length, and Sway average velocity with eyes open and closed. As a result, there was a significant decrease in pain in both groups, and there was also a significant difference in the amount of change between groups. In balance, all variables except C90 of CG showed significant changes after intervention, and there was a significant difference between C90 and Vel with eyes closed in the amount of change between groups. Therefore, we believe that CPM and active exercise program using sling are effective interventions to reduce pain and improve balance in total knee replacement patients.
