Purpose: This study was conducted in order to develop an instrument for the Korean Osteoarthritis Impact Measurement scale (KAIMS) in hip and knee osteoarthritis patients. Methods: A sample of 426 subjects was recruited in Ulsan metropolitan city (six hospitals and clinics) and Andong city (five hospitals and clinics) from June 2010 to May 2011. Item internal consistency and item discriminant validity were analyzed on the item-level, and floor (%) and ceiling (%) effect were analyzed on the scale-level. Exploratory factor analysis was performed for construction of items in the KAIMS instrument; confirmative factor analysis was also performed to test the fit of the model. Results: In 426 respondents, age was 64.3 years. The reliability for r coefficient 0.90 (mobility) and 0.89 (pain and stiffness) (Cronbach's alpha 0.95, 0.95 respectively) was high in the test-retest, and there was no significant difference in paired t-test (p>0.05). Item internal consistency (${\alpha}=0.92$, ${\alpha}=0.87$ respectively) was also high. It was constructed of two factors (mobility, pain and stiffness dimension) and nine items in explanatory factor analysis; results of confirmatory factor analysis also indicated that the dimensional structure model was fitted well in the test of model fit (${\chi}^2=83.83$, df=26, p=0.000; RMR=0.05; GFI=0.96; AGFI=0.83). Conclusion: In conclusion, the results of this study showed that the KAIMS that was developed was a reliable and valid instrument for measurement of osteoarthritis (OA) patients. We recommend further research for additional development of the instrument on OA in Korea.

본 연구는 다이오드레이저가 골관절염에 주는 영향을 평가하기 위해 실시되었다. 연구에는 10주령의 수컷 Sprague-Dawley 랫드 60마리를 사용하였고 전십자인대의 절단 (ACLT)으로 골관절염을 유발하였다. 대조군, sham군, ACLT군, ACLT와 레이저조사를 병행한 군 (ACLT+L), ACLT와 meloxicam 투약을 병행한 군 (ACLT+M)의 다섯 개의 실험군으로 나누어 연구를 진행하였다. 8주간의 연구 기간 동안 808-nm indium-gallium-arsenide (InGaAs) 다이오드레이저 조사 방법으로 Low-level laser therapy (LLLT)를 일주일에 두 번 랫드의 수술 한 오른쪽 다리에 조사하였다. 수술 후 2주, 4주, 8주에 방사선학적, 형태학적, 조직병리학적 평가를 실시하였다. 8주에 실시한 방사선학적 평가와 일반 혈액검사, 혈청 화학 검사에서는 군 간의 유의한 차이가 나타나지 않았다. 형택학적 방법과 조직병리학적 방법으로 수술 후 2주, 4주, 8주의 ACLT+L 군과 sham 군을 비교 했을 때 ACLT+L 군에서 유의하게 연골의 손상정도가 높은 것으로 나타났다. ACLT+M 군 또한 sham 군과 비교했을 때 연골의 손상이 심한 것으로 나타났다. LLLT는 ACLT 모델에서 골관절염을 예방하는 효과는 제한적이었으며, 오히려 연골의 손상을 가속화 시키는 것으로 평가 되었다. LLLT가 세포의 생존에는 영향을 주지 않으므로 레이져에 의한 직접적인 연골손상 발생보다는 레이저의 통증완화효과로 인해 불안정한 무릎관절을 계속해서 사용함으로써 연골의 손상이 가속화 된 것으로 생각 된다.

Purpose: This study examined the effects of heat therapy combined with aromatherapy on pain, flexibility, sleep, and depression in elderly women with osteoarthritis. Methods: This study was designed as a nonequivalent control group quasi-experimental study based upon data acquired through a pre-post test. The experimental group (n=21) was treated using an aroma-permeated hot compress applied to the knee. The cotton towel was heated in a microwave to $45^{\circ}C$, and 2~3 drops of lavender were applied on it. The towel was wrapped with plastic bag to prevent aroma leakage and retain heat. The treatment was applied the towel for 20 minutes, three times a day for 3 weeks. The control group (n=24) was not given any treatment. Data were collected using a VAS(100mm) for pain, questionnaire for sleep and depression, and a goniometer for knee flexibility. The data were analyzed with ${\chi}^2$-test and t-test using SPSS/Win18.0. Results: There were significant differences in knee pain (p=.001) and flexibility (p<.001), subjective quality of sleep (p=.020) and depression (p=.003) between the groups. Conclusion: Heat therapy combined with aromatherapy may be an effective nursing intervention and self-care technique to ameliorate pain and depression and to improve flexibility and sleep in elderly suffering from osteoarthritis.

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.

Purpose: Osteoarthritis occurs in many different joints of the body, causing pain, stiffness, and decreased function. The knee is the most frequently affected joint of the lower limb. The aim of this study was to investigate the differences of biomechanics between independent gait and anterior walker dependent gait of patients with osteoarthritis of the knee. Methods: Lower limb joint kinematics and kinetics were evaluated in 15 patients with knee osteoarthritis when walking independently and when walking with an anterior walker. Participants were evaluated in a gait laboratory, with self-selected gait speed and natural arm swing. Results: When walking with a dependent anterior walker, participants walked significantly faster (p<0.01), using a longer stride length (p<0.01), compared to independent gait. When walking with a dependent anterior walker, participants exhibited significantly greater knee flexion/extension motion (p<0.01) and lower knee flexion moment (p<0.05) compared to independent gait. When walking with a dependent anterior walker, participants showed significantly greater peak ankle motion (p<0.01), ankle dorsiflexion/plantarflexion moments (p<0.01), and ankle power generation (p<0.05) compared to independent gait. Conclusion: These biomechanical properties of gait, observed when participants walked with a dependent anterior walker, may be a compensatory response to impaired knee function to allow sufficient power generation for propulsion. Therefore, rehabilitative strategies for patients with osteoarthritis of the knee are needed in order to improve not only knee function but also hip and ankle function.

The purpose of this study was to investigate the biomechanical effects of wearing different type of insole shoes on gait characteristics in patients with knee osteoarthritis. Seven patients with knee osteoarthritis (Grade 3 & 4 by Kellgren & Lawrence) were participated in the study. They wore two different type of shoes (with Gel-type Insole: GIS, with Normal insole: NIS) during gait. Three dimensional cinematography and Ground Reaction Force(GRF) data were used to get the maximal value of horizontal distance between the center of pressure in GRF and knee joint center, GRF in mediolateral direction, peak value of GRF in frontal plane, vertical compressive force and adduction moment in knee joint. The results were as follows: The maximal value of horizontal distance between the center of pressure in GRF and knee joint center was smaller in GIS than NIS. The peak value of GRF in mediolateral direction was found in 30% of gait cycle, five subjects wearing GIS showed lower value of peak GRF in mediolateral direction than wearing NIS. The peak value of GRF in frontal plane and vertical compressive force in knee joint did not show any difference between GIS and NIS. The adduction moment in GIS decreased in the late stance of gait and the mean value of the adduction moment in GIS smaller than that in NIS. GIS may help to move quickly knee joint center to the center of pressure in GRF, therefore it may prevent increasing the adduction moment in knee joint.
