This study was to research the characteristics of the body shape of Korean woman farmers by the major crops. Four hundred ninety-five Korean woman farmers from 9 different area such as Kumi, Damyang, Iksan, Injae, Chungju, Choongju, Haman, Whasung, and Whasoon volunteered for this study. Their major crops were the rice, the pepper, the water melon, the strawberry, the wild rocambole, the sweet persimmon, the grapes, the mushroom, and the chrysanthemums. Twelve body angles were measured from archived the somatotype photographs of the front, the side, and the back. Questionnaires of SF-36 and the farmer's symptom, and the farm-work related movements were surveyed. The results were as follows; 1. Farmers had lower health levels in physical role limit, pain, vitality, and physical function than other occupational workers. 2. Most farmers acted the high-risk ergonomics motions when they worked in the farm. 3. There were significantly different on the both shoulder angles, the hip tangential line slope, the hip breadth angel, in frontal ankle-knee angle, the bending back angle, the dropping breast slope, the abdominis media angle, under the abdominis media angle, the glutea angle, under the glutea angle, and the sideward knee angle(p<.05). 4. Farmers cultivating the low plants such as the water melon, the strawberry, and the wild rocambole showed more banded vertebralis and side knee angles. Farmers cultivating the red pepper showed the dropping the left shoulder and O shape legs. Farmers cultivating the fruit trees such as the sweet persimmon and the grapes showed the less banded side knee angles than other farmer groups. 5. On comparing the same age, farmers showed the older's body shape in earlier and much more than the old living in the city.

The purpose of this study was to compare and analyze kinetic variables of lower limbs according to types of ankle taping in drop landing. For this, targeting seven male basketball players (average age: $20.8{\pm}0.74yrs$, average height: $187.4{\pm}3.92cm$, average weight: $79.8{\pm}7.62kg$) with no instability of ankle joints, the drop landing motion was conducted according to three types of inelastic taping (C-type), elastic taping (K-type), and no treatment (N-taping). Based on the result, the next conclusion was reached. First, the effect of taping for the players with stable ankles was minimal and the high load on ankle joints offset the fixing effect of inelastic taping. Thus the inelastic taping for the players with stable ankles did not have an effect on the control of dorsal flexion during one-foot landing. Second, increasing angular velocity by increasing the movable range of knee joints disperses impact forces, yet inelastic taping restricted the range of knee joint motion and at the same time increased angular velocity, adding to a negative effect on knee joints. Third, inelastic taping induced inefficient motion of Lower limbs and unstable impact force control of ankle joints at the moment of landing and produced maximum vertical ground reaction force, which led to an increase of load. Therefore, inelastic ankle taping of players whose jump actions occur very often should be reconsidered. Also, it is thought that this study has a great meaning in proving the problem of inelastic taping related to knee pain with unknown causes.

Objectives : The aim of this study was to evaluate the usefulness of ultrasonography of knee osteoarthritis. Methods : 124 osteoarthritis patients classified by the American College of Rheumatology (ACR) clinical criteria were included in the study. Simple X-ray and ultrasonography examination (effusion, osteophyte, articular cartilage, Backer's cyst) of knee in pain were performed. Also VAS, KWOMAC score were checked. Results : X-ray showed abnormal findings in 112 patients, but ultrasonography showed abnormal findings in all 124 patients. 12 Patients with unremarkable knee X-ray showed effusion and osteophyte in the ultrasonography. Effusion was discovered only in 18 cases of X-ray and 62 cases of ultrasonography. Group with effusion showed higher VAS mean figure but couldn't retrieve significant difference. KWOMAC showed no significant difference. Conclusions : Osteoarthritis patients with no abnormality in X-ray diagnosed abnormal findings through sonograph, which manifest that sonograph can be utilized for differential diagnosis especially sensitive on the problem of effusion.

Background: The number of old people with degenerative osteoarthritis one of the chronic disease, were constantly increased. Many researchers have made a great effort to verify the effects of ultrasound and laser therapy in degenerative osteoarthritis treatment. This study applied ultrasound-laser integration therapy on knee joint degenerative osteoarthritis and compared its effect with ultrasound and laser. Methods: We assigned 60 patients age 65 to 85 who had been diagnosed as knee joint degenerative osteoarthritis in G nursing home in Daejeon city. Randomization was done in blocks of three, holding twenty people per each group to receive either ultrasound, laser, ultrasound-laser integration therapy. This study carried out the experiment for 6 weeks to from April 17, 2010. We measured variables using visual analog scale (VAS) and pressure threshold meter (PTM) of the effects by before and after exercise. Results: It has been found that VAS was reduced and PTM was increased in all three groups. Compare with the other groups, Ultrasound-laser integration therapy group had lower VAS and higher PTM than ultrasound therapy and laser therapy group. Conclusions: These results lead us to the conclusion that ultrasound-laser integration have influenced the pain reduction of the knee degenerative osteoarthritis.

The localized form of a giant cell tumor of tendon sheath rarely affected the large weight-bearing joints. Only four cases of localized giant cell tumor arising in the knee joint could be found in the literatures. Physical examination of the affected knee could show pain, swelling, locking, giving way and limitation of extension, but it was difficult to differentiate from meniscal tear or cruciate ligament tear. Two cases of localized giant cell tumor of tendon sheath were incidentally found in the knees during the reconstruction of the anterior cruciate ligaments. Both tumors arising from the anterior cruciate ligament were excised arthroscopically and were confirmed to be localized giant cell tumor of tendon sheath by microscopic examination. The clinical results were good after complete excision, so we reported these cases with a review of the literatures.

The purpose of this study was to examine the validity and reliability of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)-VA3.0 in patients with hip and knee osteoarthritis (OA). The sample consisted of 301 patients who had received treatments at the physical therapy units of 5 medical institutions in Andong City in june 2006. Questionnaires on the WOMAC were recruited by 12 physical therapists. The internal structure and reliability of the scales were evaluated by means of item-internal consistency (Cronbach's alpha coefficient: ${\alpha}$), item-discriminant validity, and Pearson's relation coefficient. To explore construct validity, we conducted a principal component factor analysis with varimax rotation analysis. The criterion for factor extraction was an eigenvalue >1.0. The average age of the patients was 62.1 years. All WOMAC subscales (pain, stiffness, and physical function) were internally consistent with Cronbach's coefficients of .81, .91, and .80, respectively. The internal consistency reliability of item-each scale were also internally consistent with Cronbach's coefficient of .89 (Pearson's correlation coefficient: .71~.84), .93 (.89~.91), and .96 (.67~.91), respectively. However, high correlation was found among 3 items (.66~.83, .66~.67, and .67~.83), so the item-discriminant validity was low (${\alpha}$ coefficient: .81, .91, .80, respectively). The construct validity by factor analysis was low because it was not consistent With WOMAC-VA3.0. In conclusion, the results reported here confirm the reliability of the WOMAC in patients with OA of the hip and knee. The collection of information on the hip and knee osteoarthritis using this instrument was acceptable to patients. A further prospective multi-center study will be necessary to prove the construct validity.

PURPOSE: This research was intended to investigate the influence to function recovery at the early stage after surgery, by conducting Multipath Electrical Simulation and isometric exercise treatment as early stage medical treatment method for Total knee arthroplasty patients. METHODS: The subject of 30 patients having Unilateral Total knee arthroplasty over age 65, Multipath Electrical Simulation and isometric exercise (experiment group I), Conventional Electrical Simulation and isometric exercise (experiment group II) and isometric exercise (control group). The intervention was performed in 5 times per a week and 60 minutes per a day during 4 weeks. We performed research by conducting Neuromuscular Electrical Stimulation and isometric exercise together and measured pain, range of motion, muscle strength and gait ability before and after intervention. RESULTS: The result showed therapeutic improvement in experiment group I, experiment group II and control group, but Multipath Electrical Simulation and isometric exercise showed significant improvement in function recovery of early stage compared to Conventional Electrical Simulation and isometric exercise, only isometric exercise. CONCLUSION: Based on research result, in order for early state function recovery of Total knee arthroplasty patients, when conducting neuromuscular electrical stimulation and isometric exercise together, especially when applying Multipath Electrical Stimulation, we could know that it showed more significant improvement to function recovery after surgery. Also, we suggest that Multipath Electrical Simulation may become a useful tool as a method for intervention and performing in various diseases for weakening of Quadriceps muscle.

The surface electromyographic(sEMG) analyses were knee joint angle during open kinetic chain exercise (OKC) and close kinetic chain exercise (CKC) in vastus medialis (VM), vastus lateralis (VL), and rectus femoralis (RF). Ten subjects with normal , aged 20 to 30(X=27.4, SD=3.23), were randomized Statistical techniques for data analysis were applied paired t-test. The 0.05 level of significane was used as the critical level for rejection of the null hypotheses for the study. And the results were: 1) Both OKC and CKC improved the strength of quadriceps muscle as the knee joint flexion was increased. 2) In OKC, the strength of VM was improved the most at the 30 degree angle. 3) In CKC, the strength of VM was improved the most at the 30 degree angle. 4) The VM/VL ratio was the largest at the 10 and 20 degree angles in OKC and CKC. 5) The VM/VL ratio at 10, 20, and 30 degree angles was significantly different between OKC and CKC (P < 0.05). Base on the results, the OKCE is recommended for the knee joint patients, especially for the patellofemoral pain syndrome patients, during the early phase of rehabilitation. In order to improve strength of the quadriceps, muscle strength training at 30 degree angle is recommended. In order to improve VM/VL ratio, 10 and 20 degree angles are recommended during OKCE and CKCE, respectively. Future researches are warranted comparing electromyographic analysis between OKCE and CKCE in the quadriceps at a certain work lead, and muscle strength performance in the quadriceps at different positions of foot.

Background: Spinal Mobilization is one of the manual therapy technique that clinicians have used to treat pain, however, there is still a lack of research on changes in strength in healthy people. Objectives: To investigate the effect of posterior-anterior lumbar mobilization on lower limb strength in healthy individuals. Design: Two-group pretest-posttest design. Methods: In this study, 23 healthy subjects aged 20 years were assigned to 12 lumbar mobilization group (LMG) and 12 sham group (SG) to perform intervention and measurement through pre- and post-design. Intervention was performed in LMG with grade III~IV on L3-5 of the lumbar spine, and lumbar mobilization was performed for each segment. After intervention, knee flexion and extension strength were measured. To measure the main effect on muscle strength, a comparative analysis was conducted using paired t-test and independent t-test. Results: In LMG, knee flexor and extensor strength were increased significantly at 60°/s (P<.05). In addition, the extensors of LMG and SG were significantly different only at 60°/s, and the flexors were significantly different between groups at both 60°/s and 180°/s (P<.05). Conclusion: In healthy individuals, lumbar mobilization results in improvement of strength of knee flexor and extensor, and additional experiments on the effect of mobilization on the lumbar spine on functional changes in the lower limbs will be needed.
