Purpose: This study was to find that what mechanism take effects that was Adjuvant Induced Arthritis in Sprague-Dawley rat and then treated the swimming and low power laser. Methods: Adjuvant Induced Arthritis was induced 24 Sprague-Dawley rat by the subcutaneous injection of a 0.2ml Freund's Complete Adjuvant into the right hind paw and right knee joint. Second injection used of 0.05ml Freund's Complete Adjuvant by same method. Arthritic rat were divided 3 groups; arthritic swimming group, arthritic laser group and case control group. The author performed several experimental tests which were the hind paw thickness, step length, knee joint space, activity of enzyme. Results: Hind paw thickness decreased in swimming and laser group. Left step length and knee joint space increased in swimming and laser. Conclusion: Swimming and low power laser therapy on the Adjuvant Induced Arthritis in rats does effective for the rheumatic arthritis therapy by decrease of hind paw thickness, increase of opposite side step length, increase of activity of albumin and IgG and increase of knee joint space.

Objective: This study was designed to compared the effect of general acupuncture on degenerative arthritis of knee joint with 8 constitution acupuncture by Visual Analogue Scale(VAS). Methods: VAS was used for this research, with the pain indicator of 10 and 0 which represents a pain of first visit and a status of no pain respectively. Two groups, consisting of 40 patients, was randomly allocated for this research. SPSS(Statistic Program for Social Science) 10.0 for window was used for a statistical analysis. Independent T-test and Mann Whitney U test was performed to evaluate the improvement of each group by the treatment number and to compare that of two groups. Results: As a result of the comparison analysis between two groups after 20th treatment, the improvement of subjective symptoms in 8 constitution acupuncture group was shown more effective than that in general acupuncture group, while, After 10th treatment, there was no significant difference between two groups in VAS. Conclusion: It is suggested that the effect of 8 constitution acupuncture should be significantly different from that of general acupuncture on degenerative arthritis of knee joint. Further study is needed to confirm the effectiveness of 8 constitution acupuncture.

결절종(ganglion cyst)은 관절 또는 건막과 연결된 두꺼운 결체 조직내에 맑고 높은 점도의 액체를 함유한 낭포성 종양으로 슬관절 주위에서는 흔하지 않다. 73세 여성의 슬관절 내측에 발생한 딱딱한 종괴가 만져졌으며 종양의 가능성을 의심할 만 하였다. 이것을 초음파로 간단하게 결절종임을 밝혀내고 실시간으로 병변내 주사 바늘의 위치를 확인하면서 흡인하여 확진할 수 있었다. 초음파는 낭종의 진단에는 매우 편리하고 유용한 진단 기구임을 알 수 있었다.

Objectives : This study is performed for proposing reasonable clinical study protocol at International standard clinical study of osteoarthritis of Knee Joint. Methods : We gave the eighteen oriental medicine doctors the questionnaire and the video about female patient who diagnosed Knee joint of osteoarthritis above 60 years old and they tested same patients using differentiation of symptoms and signs. Then they retested it after We educated them with diagnosis education text. Conclusion : The improvement of diagnosis agreement can be possible by developing standardized the same patients using differentiation of symptoms and by reeducation about it.

Purpose: This study examined the effects of flexible flatfeet on the accuracy of knee joint motions in closed and open kinetic chain tasks. Methods: Twenty-four healthy participants were recruited for this study. The subjects were divided into two groups using a navicular drop (ND) test: flexible flatfoot group (n=12, male: 6, aged $22.00{\pm}2.22years$) and age-matched control group (n=12, males: 6, aged $22.17{\pm}1.53years$). The accuracy of knee motion was measured quantitatively by tracing through the flexion and extension motion of the knee joints in the closed kinetic chain and the open kinetic chain. Results: There was a significant difference in the accuracy index between the groups in closed kinetic chain task, but there was no significant difference in the open kinetic chain task. In addition, there was a significant difference in the accuracy index between the closed kinetic chain and the open kinetic chain task in the flexible flatfoot group. In addition, a significant negative correlation was observed between the ND and accuracy index in the closed kinematic chain task, but there was no significant relationship between the ND and accuracy index in the open kinematic chain task. Conclusion: Flexible flatfeet can affect the accuracy of the adjacent joints, such as the knee joint in the closed kinematic chain.

Objective: The purpose of this study was to investigate the effects of different frequency on muscle function of the thigh in patients with degenerative knee arthritis during the functional electrical stimulation (FES). Method: For this study, 16 male participants over 65 who patients with degenerative knee arthritis were recruited as research participants. In this research, isokinetic muscular function, EMG, and joint position sensation were performed after FES treatment was applied for three conditions (FES 20, FES 50, and Without FES). For each dependent variable, one-way ANOVA with repeated measures was to determine whether there were significant differences among three different conditions (p<.05). When a significant difference was found, post hoc analyses were performed by using the contrast procedure. Results: When compared to FES 50 and without FES, FES 20 causes significant increase in isometric knee extension strength. No significant differences were found in EMG values across different EMS conditions. Conclusion: The present study examined isokinetic muscular function, EMG, and joint position sensation in order to investigate the effects of different frequency muscle function of knee extensors during the functional electrical stimulation. The results of this study showed that FES with 20 Hz frequency had positive effect on knee extensor. Based on the findings of the present study, FES with lower frequency may help the performer to focus on developing strength in knee extensor muscles.

The isometric area of the anterior cruciate ligament was calculated during knee flexion-extension. Flexion-extension motion data of the joint were obtained using Fastrak and a three-dimensional motion measurement system. A total of five subjects were seated on a flat table and the tibia sensor position was measured with the femur fixed on the table. A three-dimensional knee model was constructed using a graphic tool to simulate the knee motion. Twenty seven positions of the tibia region and forty two positions of the femur region were selected and the distances between the determined tibial and femoral points were calculated. Highly isometric areas were found and displayed as three dimensional aspects.

The isometric position of the anterior cruciate ligament was calculated during flexion-extension. Flexion-extension motion data of the knee joint were obtained by Fastrak, a three-dimensional motion measurement system. A subject was seated on a flat table and the tibia sensor position was measured with the femur fixed at the table. A three-dimensional knee model was constructed using a graphic tool to simulate the knee motion. Three surgical positions of the femoral tunnel were selected and the distances between the determined tibial tunnel and each femoral tunnel were calculated. The maximum elongation position was found to be in the ten thirty direction of clock.

This paper describes the possibility of evaluating and classifying arthritic pathology using the acoustical analysis of knee joint sound. Six normal subjects and 11 patients with knee problems were enrolled. Patients were divided into the 1st patient group which required an orthopeadic surgery and the 2nd patient group of osteoarthritis. During sitting and standing periods, subjects' active knee flexion and extension were monitored. Fundamental frequency, mean amplitude of pitch, jitter and shimmer were analyzed according to the position. The results demonstrate that the values of fundamental frequency, jitter and shimmer of the 2nd patient group were larger than others and changed unstably. The values of the standing position were larger than the sitting position.
