The purpose of this research was to analyze the effects of the increase of the femoral anteversion angle on the unbalanced quadriceps femoris muscle causing the increase of the valgus force on the knee joints and patellofemoral pain syndrome by comparing with the group that shows the smaller femoral anteversion angle. The method for the research was to compare the femoral muscle's activity while the subjects were maintaining the knee joint flexed isometrically for 10 seconds. The evaluation tool for femoral muscle's activity was QEMG-4 (model LXM 3204). The results were as followings. Firstly, in case of the experimental group, the muscle strength of the vastus lateralis muscle was strong while the rectus femoris and vastus medialis were weak. In these facts, we can see the statistically meaningful difference in vastus medialis muscle activity. Secondly, in the muscle activity analysis for vastus lateralis and medialis of the two groups, we could see the vastus lateralis muscle was strong in anteversion wider for experimental group while the vastus medialis muscle contracted far more stronger in anteversion smaller for control group. From these results, we can see the significant differences in muscle recruitment between the two groups. Above results show that if the anteversion becomes wider, vastus medialis muscle will become seriously weaker, on the other hand, vastus lateralis act stronger.

Objectives The purpose of this study was to report the effect of Korean medicine treatment, including the application of joint mobilizing chuna, by reporting two cases after tibial plateau fracture surgery. Methods Two patients with tibial plateau fractures were treated using joint mobilizing chuna, myofascial chuna, acupuncture, and herbal medication. The effect of the treatments was evaluated using the range of motion, manual muscle test, numeric rating scale, and Korean Knee Injury and Osteoarthritis Outcome Score. Results In both cases, the range of motion, muscle strength, and pain were significantly improved. In particular, the range of motion for knee joint flexion increased by 47° in case 1 and 30° (right) and 42° (left) in case 2. Conclusions Korean medicine treatment, especially joint mobilizing chuna, may be an effective intervention for rehabilitation after tibial plateau fracture surgery.

Objective : This study is designed to evaluate the correlation between the data of DITI (Digital Infrared Thermographic Imaging) and the clinical symptoms in the patients with low back pain. Methods : Among the outpatients with back pain who visited to Department of Acupunture & Moxibustion, Tae gu Oriental Hopital of Kyung San University from January 2000 to August, we selected 115 cases that examined DITI. We evaluated the correlation between the data of DITI examination and the clinical symptoms (Distribution of Sex and Age, Duration of Disease, Main Sign, Grade of Clinical Symptoms, Diagnosis according to Symptoms(辨證),) in the patients with low back pain. Results & Conclusion : 1. The thermal changes in terms of the duration of disease : The acutest period has the highest thermal change. Also, the longer the duration of disease was, the higher the termal change was. It increased in the order of the acutest period, the less acute period, and the the chronical period. 2. Thermal changes due to the main symptom : The degree of thermal change was as follows (from the highest to the lowest): first, back and knee pain, second, back and leg pain, third, back and buttock pain, fourth, numbness of leg, and fifth, back and dorsum pain. 3. Thermal changes in terms of the grade of clinical symptoms : The more servious the symptoms were, the higher the thermal change was. It was increased in the order of Gr 1, Gr 2, Gr 3, and Gr 4. 4. Thermal changes depdning on symptoms diagnosis : Chwaseom(挫閃) has the highest temperature, $0.87{\pm}0.49^{\circ}C$. 5. Thermal changes before and after treatment : Before treatment, the average thermal change was $0.83^{\circ}C$ but after treatment, it was decreased to $0.38^{\circ}C$. For the above symptoms, if DITI is used, the diagnosis is easier based on the medical history of the patient who has back pain, and the degree of pain. However, if thermal change is soly used for diagnosis, it will be hard to determine the nature of sickness. Therefore, it should be folllowed by other supplementary examination.

This study was designed to identify the effect of various decline boards and postures of lower extremities on surface electromyographic (EMG) activity of knee muscles during isometric single-leg decline squat exercises. The subjects were twenty young male adults who had not experienced any knee injury and their Q-angles were within a normal range. They were asked to perform single-leg decline squat exercises in five various conditions. The EMG activities of the gluteus maximus (GM), vastus lateralis (VL), vastus medialis (VMO), tibialis anterior (TA), and gastrocnemius (GCM) muscles were recorded in five various single-leg decline squat exercises by surface electrodes and normalized by maximal voluntary isometric contraction (MVIC) values. The normalized EMG activity levels were compared using one-way ANOVA with repeated measures. The results of this study were as follows: 1) Exercises 2 and 4 produced significantly greater EMG activity of VMO than did exercise 1 ($p_{adj}$<.05/10), 2) The VMO/VL ratio of EMG activity of exercise 4 was the highest, producing a significantly greater ratio than exercise 1 ($p_{adj}$<.05/10). These results show that single-leg lateral oblique decline squat exercise is the best exercise for selective strengthening of VMO, and the posture of the contralateral leg does also affect strengthening of VMO, but we'll need to research patellofemoral joint compression for clinical application of single-leg lateral oblique decline squat exercises.

Purpose: The aim of this study was to determine the effectiveness of a community-based muscle and joint self-management program with muscle stretching and muscle strengthening exercises for community-dwelling older adults. Methods: The study was a pre-and-post design in a single group, which examined the effects after the intervention of muscle and joint self-management program for 6 weeks, on the 42 subjects of the elderly who registered in a Community Senior Center in J city. Data analyses were conducted with paired t-test by using a SAS (version 9.2 for Windows) program. Results: The effectiveness of muscle and joint self-management program on shoulder flexibility and right knee extension (flexibility) were significantly improved (t= 2.72, p= .010; t= -2.26, p= .029). Joint symptoms (pain, stiffness), physical functioning, depression, fatigue, and left knee extension were not significantly improved after the muscle and joint self-management program. Conclusion: The results showed the possibility of this 6-week exercise program in improving shoulder and knee flexibility for community-dwelling older adults.

Purpose: The purpose of this study was to determine the effects of a lower extremity exercise program on muscle strength and flexibility in women with knee osteoarthritis. Method: This study was conducted using a non-equivalent control group pretest-posttest design. The participants were 35 women with knee osteoarthritis. The experimental group performed the lower extremity exercise program, which was an adapted BeHaS exercise program developed by Kim(2006). It consisted of approximately 65-130 minutes per one session, two days a week, for twelve weeks. Lower extremity muscle strength was measured by the Seated Leg Press Machine (TY-H2217, made in Korea), back muscle strength by back muscle strength scale (TKK 5402, made in Japan) and flexibility, by Sit and Reach tester (01285, U.S.A). Data were gathered from September 2005 to March 2006. Frequency, $X^2$ test and t-test were used to analyze the data. SPSS Win 11.0 was used to assist analysis. For normal distribution of data, Kolmogorov-Smirnov test was done. Results: There were statistical differences in the mean strength of both legs together, strength in leg with more pain(p=.044; p=.046), sit and standing time (p=.007), and back strength (p=.021). Conclusion: Based on these results, it can be concluded that a lower extremity exercise program can help improve lower extremity muscle strength in women with osteoarthritis.

Most exercise for Patellofemoral pain syndrome (PFPS) has focused on selectively strengthening the vastus medialis oblique muscle (VMO). Although open chain knee extension exercises are effective for increasing overall quadriceps strength, they are not always indicated for PFPS rehabilitation. This study was designed to identify the effect of combined posture of lower extremity on Electromyographic (EMG) activity of the vastus lateralis muscle (VL) and VMO during static squat exercises. The subjects were twenty young adult males who had not experienced any knee injury and their Q-angle was within a normal range. They were asked to perform static squat exercises in five various postures using their lower extremities. The EMG activity of the VL and VMO were recorded in five exercises by surface electrodes and normalized by %MVC values derived from seated, isometric knee extensions. The normalized EMG activity levels (%MVC) of the VL and VMO for the five postures of the lower extremities were compared using one way ANOVA with repeated measures. Results of repeated measures of ANOVA's revealed that exercise 3 and exercise 5 produced significantly greater EMG activity of VMO/VL ratios than exercise 1 (p<.05). When the static squat exercise was combined with hip adduction and toes pointed outwardly, the EMG activity of VMO/VL rates was increased. The EMG activity of VMO/VL ratio was highest during static squat exercises performed on a decline squat. These results haveimportant implications for progressive and selective VMO muscle strengthening exercises in PFPS patients.

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelve meridians(WSBTM) will be representative of measurements of the twelve meridians, to measure the electric potentials of 13 patients with Arthroncus of Knee(슬안풍<膝眼風>, AK), to find out the characteristic of meridian system in patients with AK. Methods : Electric potentials of well and sea points in the meridians in twenty one patients with the pain in the lion diagnosed as AK were repeatedly measured by physiograph(PowerLab). Measurements of those electric potentials were analyzed by factor analysis. Results : Their electric potentials at the left and right side were factors which are different from each side. In the left side, Factor 1 included Small Intestine, Pericardium, Spleen, Kidney meridian, and Factor 2 included Heart, Tripple Energizer, Bladder, Liver meridian. Factor 3 included Large Intestine, Stomach, Gall bladder meridian, and Factor 4 included Lung meridian. In the right side, Factor 1 included Heart, Pericardium, Tripple Energizer, Spleen, Bladder meridian and Factor 2 included Lung, Liver, Gall bladder meridian. Factor 3 included Small Intestine, Stomach, Kidney meridian and Factor 4 included Large Intestine Meridian. Conclusions : The electric potentials of AK differ from those of normal bodies as well as of bodies with other diseases-shoulder lesions, waist lesions, Lumbago due to Strain and Contusion-. Thus electric potentials of well and sea points might be the representative meridian to show their characteristics.
