Objective : To evaluate the clinical and radiological outcomes of lumbar interbody fusion and its correlation with various factors (e.g., age, comorbidities, fusion level, bone quality) in patients over and under 65 years of age who underwent lumbar fusion surgery for degenerative lumbar disease. Methods : One-hundred-thirty-three patients with lumbar degenerative disease underwent lumbar fusion surgery between June 2006 and June 2007 and were followed for more than one year. Forty-eight (361%) were older than 65 years of age (group A) and 85 (63.9%) were under 65 years of age (group B). Diagnosis, comorbidities, length of hospital stay, and perioperative complications were recorded. The analysis of clinical outcomes was based on the visual analogue scale (VAS). Radiological results were evaluated using plain radiographs. Clinical outcomes, radiological outcomes, length of hospital stay, and complication rates were analyzed in relation to lumbar fusion level, the number of comorbidities, bone mineral density (BMD), and age. Results : The mean age of the patients was 61.2 years (range, 33-86 years) and the mean BMD was -2.2 (range, -4.8 to -2.8). The mean length of hospital stay was 15.0 days (range, 5-60 days) and the mean follow-up was 23.0 months (range, 18-30 months). Eighty-five (64.0%) patients had more than one preoperative comorbidities. Perioperative complications occurred in 27 of 133 patients (20.3%). The incidence of overall complication was 22.9% in group A, and 18.8% in group B but there was no statistical difference between the two groups. The mean VAS scores for the back and leg were significantly decreased in both groups (p < 0.05), and bony fusion was achieved in 125 of 133 patients (94.0%). There was no significant difference in bony union rates between groups A and B (91.7% in group A vs. 95.3% in group B, p = 0.398). In group A. perioperative complications were more common with the increase in fusion level (p = 0.027). Perioperative complications in both groups A (p = 0.035) and B (p = 0.044) increased with an increasing number of comorbidities. Conclusion : Elderly patients with comorbidities are at a high risk for complications and adverse outcomes after lumbar spine surgery. In our study, clinical outcomes, fusion rates, and perioperative complication rates in older patients were comparable with those in younger populations. The number of comorbidities and the extent of fusion level were significant factors in predicting the occurrence of postoperative complications. However, proper perioperative general supportive care with a thorough fusion strategy during the operation could improve the overall postoperative outcomes in lumbar fusion surgery for elderly patients.

Purpose: This study was done to evaluate the mean venous velocity (MVV) response with knee and thigh length compression stockings (CS) versus intermittent pneumatic compression (IPC) devices in immobile patients with brain injuries. Methods: We carried out a randomized controlled study. We analyzed both legs of a randomly chosen sample of 43 patients assigned to one of 4 groups (86 legs). The patients were sequentially hospitalized in the intensive care unit (ICU) in "S hospital" from November 2005 to December 2006. The base line and augmented venous velocity was measured at the level of the common femoral vein. We applied leg compression 42 times over 7 days (for 2 hours at a time at 2 hour intervals). Results: There was a statistical difference among the 4 groups. The difference for the "IPC" group was more significant than the "CS" group. Conclusion: These results indicate that the application of IPC can be considered as an effective method to prevent deep vein thrombosis for immobile patients with brain injury.

Objective To evaluate the association between progression of curvature of scoliosis, and correction for functional component in patients with juvenile idiopathic scoliosis (JIS). Methods We retrospectively reviewed medical data of patients prescribed custom molded foot orthosis (FO) to correct inequality of RCSPA (resting calcaneal stance position angle), and chose 52 patients (26 females, 26 males) with Cobb angle ${\geq}10^{\circ}$ in radiology and uneven pelvic level at iliac crest by different RCSPA (${\geq}3^{\circ}$) as a factor of functional scoliosis. They had different hump angle ${\geq}5^{\circ}$ in forward bending test, for idiopathic scoliosis component. Their mean age and mean period of wearing FO were $79.5{\pm}10.6months$ and $18.6{\pm}0.70months$. Results Cobb angle was reduced from $22.03^{\circ}{\pm}4.39^{\circ}$ initially to $18.86^{\circ}{\pm}7.53^{\circ}$ after wearing FO. Pelvis height difference and RCSPA difference, were reduced from $1.07{\pm}0.25cm$ initially to $0.60{\pm}0.36$, and from $4.25^{\circ}{\pm}0.71^{\circ}$ initially to $1.71^{\circ}{\pm}0.75^{\circ}$ (p<0.01). Cobb angle improved most in 9 months. However, there was no significant improvement for those with more than $25^{\circ}$ of Cobb angle initially. Mean Cobb angle improved in all age groups, but patients less than 6 years had clinically significant improvement of more than $5^{\circ}$. Conclusion JIS can have functional components, which should be identified and managed. Foot orthosis is useful in correcting functional factors, in the case of pelvic inequality caused by different RCSPA, for patients with juvenile idiopathic scoliosis.

Objective : Standard of measurement in Korean Medicine has been changed in dynasty and location. Thus, cun (寸) and chi (尺) as unit of measurement for meridians and acupoints could be recognized as the length of equally divided portions of a certain long bone or the distance between two anatomical landmarks and as an symbolical meaning to date. The goal of this study is to propose a new standard measurement in the metric system for the relative measurement of cun and chi as unit of measurement for meridians and acupoints in normal male legs. Methods : This study was conducted by gauging each parts of normal male legs in the metric system and comparing to the relative measurement of cun and chi as follows; to calculate 1 cun, the length of each parts was divided into the unit of cun referred to Measurement of the Bone in Neijing Lingshu (靈樞 骨度篇); it was compared the unit of cun referred to Measurement of the Bone in Neijing Lingshu with cun which was calculated by dividing subject's height into 75 cun, respectively. Result : There has no significant difference in length of 1 cun among each leg's areas based on a standard of subject's height. The unit of cun by the metric length in the legs was similar to the unit of cun referred to Measurement of the Bone in Neijing Lingshu based on each subject's height. Conclusion : It is suggested that an unit of cun as the measurement for meridians and acupoints in the male legs should be considered to the ranges from 2.4cm to 2.6cm.

PURPOSE: The purpose of this study was to compare three dimensional displacement and peak velocity of the center of mass (COM) during obstacle crossing in young and older adults. METHODS: 10 young adults (6 males/4 females, $24.6{\pm}1.9$ years, age range: 22.0-26.9) and 10 older adults (1 male/9 females, $76.9{\pm}5.1$ years, age range: 65.2-81.2) participated in the study. Both groups crossed an obstacle, which is 10% of leg length, and COM was measured using motion analysis system. Independent t-test was used to find significant differences between two groups. RESULTS: The older adults showed significantly greater and faster COM displacement and peak velocity in mediolateral (M-L) direction as compared with young adults (p<.01 and p<.001 respectively). However, the young adults showed significantly greater and faster COM displacement and peak velocity in anteroposterior (A-P) direction as compared with older adults (p<.05 and p<.001 respectively). Furthermore, the young adults showed faster peak velocity of COM in vertical direction as compared with older adults (p<.001). However, no significant difference was found in the COM displacement in vertical direction between two groups. CONCLUSION: Greater and faster COM displacement and peak velocity in M-L direction in older adults were due to compensatory adjustment for appropriate contact on base of support of swing limb. Thus, the motion of the COM in M-L direction may be a crucial factor to identify risk of falls in older adults.

The purpose of this study was to investigate the dynamic balance and activity of internal oblique muscle, multifidus muscle, gluteus maximus muscle, biceps femoris muscle during the Y balance test following the wearing of pelvic compression belt. Forty healthy adults were recruited for this test. The dynamic balance score was estimated as the following: (anterior+posteromdial+posterolateral)/($3{\times}leg$ length)${\times}100$. The electromyography signals were measured through %reference voluntary contraction, which was normalized by reference voluntary contraction of Y balance test without wearing the pelvic compression belt. The paired t-test was carried out to compare the dynamic balance score and the activity of the trunk and hip extensor with and without the wearing of pelvic compression belt. The dynamic balance score of the Y balance test when wearing pelvic compression belt was significantly than when measured without wearing the pelvic compression belt (p<.05). The muscle activity of the internal oblique and the multifidus was significantly decreased when wearing pelvic compression belt (p<.05). The muscle activity of the gluteus maximus was significantly increased when wearing pelvic compression belt (p<.05). However, there was no significant difference in hamstring muscle activity, with or without wearing the belt (p>.05). In conclusion, this study shows that the wearing of pelvic compression belt affects trunk muscle and hip extensor muscle activity related to the pelvic mobility and stability and increases dynamic balance and also contributes to the stabilization of the external pelvic stabilization.

통발과 자망 등에 어획되는 게류의 측면적인 보행운동은 매우 특이하여 어획 메카니즘을 밝히는데 매우 중요한 요소가 된다. 여기서는 해운대 동백섬의 조간대에서 채집한 풀게를 사용하여 망지위에서의 직선적인 운동과 회전 운동 등을 관찰하고 다리의 보행위치와 시간적인 변화를 분석하였다. 그 결과 망지위에서의 보행운동은 착지위치에 따라 그물코 사이로 다리가 빠지게 되는 불규칙적인 움직임이 대부분이므로 여러가지 보행 요인들의 편차가 게의 크기에 관계 없이 크게 나타났다. 풀게의 망지위에서의 보폭, 보행속도, 다리간의 위상차 등은 평면에서 보다 훨씬 작았으나, 보행주기, 다리마디간의 각도 등은 평면에서 보다 양간 증가하였다. 따라서 게가 자망에 걸리는 현상은 게의 크기에 따른 다리의 보행운동과 망지의 망목크기 등을 고려하여 세밀하게 조사되어야 할 것이다.
