배경: 하지의 폐쇄성 동맥경화증을 치료하기 위해 시행한 하지동맥 혈관수술에 대한 성적을 알아보고자 이 연구를 시행하였다. 대상 및 방법: 1996년 12월부터 2004년 6월까지 하지의 폐쇄성 동맥경화증으로 수술 받은 40명의 환자를 대상으로 의무기록을 토대로 후향적 분석을 하였다. 환자의 평균 나이는 $66{\pm}8$세($47{\sim}81$세)였고 성비는 37:3 (남:여)이었다. 결과: 수술은 40명에서 시행되었으며 10명의 환자에서는 양측 하지에 우회술을 시행하였다. 수술명은 대퇴-슬와동맥 우회술-12예(30%), 대퇴-대퇴동맥 우회술-12예(30%), 대퇴-대퇴동맥 우회술+대퇴-슬와동맥 우회술-5예(12.5%), 대동맥-하지동맥 우회술-5예(12.5%), 액와-대퇴동맥 우회술-2예(5%), 장골-슬와동맥 우회술-2예(5%), 내막절제술-2예(5%)였다. 모든 혈관우회술의 우회도관은 인조혈관이 사용되었다. 평균 추적기간은 $33.2{\pm}23.2$개월($3.8{\sim}90.2$개월)이었으며 우회도관의 1년, 5년간 누적 개존율은 각각 75.5, 58.7%였다. 6예에서 수술후 하지절단술이 시행되었다. 수술 후 합병증은 8명의 환자에서 12건이 발생하였다. 재수술은 10예에서 시행되었다. 결론: 본원에서 시행한 하지동맥 우회술은 비교적 양호한 개존율을 보였으나 적지 않은 환자에서 우회도관 폐쇄로 인한 재수술이 필요하였다. 하지의 폐쇄성 동맥경화증의 치료성적을 향상시키기 위해서는 동맥경화증의 진행을 억제할 수 있고 우회술의 장기 개존율을 높이는 획기적인 치료법이 연구되어야 할 것으로 생각된다.

이 연구는 태권도학과 시범단 8명과 일반학생 8명을 대상자로 선정을 하여 태권도 발차기 동작 시 숙련도에 따른 체간과 하지근육의 근 활성도 비교를 목적으로 실시되었다. 태권도 앞차기, 돌개차기, 뒤후려차기 동작 시 이용되는 주요근육을 표면근전도를 이용하여, 무릎을 들어올리는 동작(P1)과 발을 차는 동작(P2)구간별로 근 활성도를 비교분석하여 다음과 같은 결론을 얻었다. 앞차기 동작 시에는 비숙련자들은 체간의 하부복직근의 활성도와 차는발의 대퇴이두근 및 지지발의 내측광근 및 외측비복근의 활성도가 숙련자보다 높고, 허리세움근 2개의 근활성도는 낮은 것으로 나타났다. 돌개차기(턴차기) 동작 시 회전동작에서는 숙련자들의 대퇴이두근과 척추근의 활성도가 비숙련자보다 높고, 차는동작에서는 하지 근 활성도는 대퇴이두근의 활성도가 높게 나타났다. 뒤후려차기 동작 시 비숙련자들의 차는발 외측비복근과 지지발의 대퇴근육 3개의 근 활성도가 숙련자보다 높게 나타났다. 이상의 결과를 종합해 보면, 숙련자들은 회전동작에서 체간을 사용하며 빠르게 회전하고 차는 발의 근 활성도가 높지 않지만, 비숙련자들은 차는발과 지지발에 근 활성도가 높게 나타났으며, 이는 차는 동작에서 균형을 유지하기 위하여 체간근육보다는 하지에 힘이 들어가 비효율적인 동작을 하는 것으로 나타났다.

Purpose: This study was to verify the effect of muscle strengthening exercises using a Thera-Band on the lower limbs. Methods: The design utilized for this study was a nonequivalent control group pretest-posttest design. A control group (16) and experimental group (16) were selected from stroke patients of K Oriental Medicine Hospital who were hospitalized for 5 months from December 2005 through April 2006. While only acupuncture therapy and physical therapy were used on the control group, acupuncture, physical therapy and additional muscle strengthening exercises using a red thera band were used on the experimental group. Muscle strengthening was performed 20 minutes per session, more than one session a day for 4 weeks. Hypotheses for this study were verified using Two-way repeated ANOVA and ANCOVA using a pre test score as a covariate. Results: The experimental group with thera band muscle strengthening exercises showed a decrease in asymmetry weight loading percentage(F=14.704, P= .010), range of knee (Z=-3.15, P= .001) & deep tendon reflex score(Z=-2.52, P= .012) and moving performance(F=12.328, P= .001)compared to the control group. Conclusion: It is confirmed that muscle strengthening exercises using a Thera-Band can be used as an effective nursing intervention to improve the function of the lower limb of hemiplegic stroke patients.

Purpose : This study was performed to find out the influence of the change on proprioception and coordination of the lower limb by experimentally induced paraspinal muscle fatigue, Methods : Twelve subjects(6 males, 6 females) with no history low back and lower limbs problem volunteered for this study. Subjects were pre-tested proprioception and coordination using the MR-FSS(Mornitored Rehab Functional Squat System). And then the subjects performed isometric paraspinal muscles contraction for induced muscle fatigue. Muscle fatigue was defined surface EMG(MP 150). After isometric contraction, the subjects were post-tested using the MR-FSS. Results : In comparison of coordination, deviation of concentric coordination was increased(from $0.50{\pm}0.13cm$ to $0.67{\pm}0.21$)(p<0.05) and deviation of eccentric coordination was also increased(from $0.51{\pm}0.15cm$ to $0.70{\pm}0.26cm$)(p<0.05). And deviation movement of proprioceptive test was increased(from $4.98{\pm}1.80cm$ to $5.69{\pm}1.98cm$), but there was no significant different(p>0.05). Conclusion : Fatigue of paraspinal muscles was decreased concentric and eccentric coordination of the lower limb.

PURPOSE: The purpose of this study was to determine the effect of corrective exercise on hip joint range of motion, lower limb alignment, radiographs of hip and knee joints, and quadriceps muscle activity in a patient with knee joint valgus deformity. METHODS: A single-subject A-B-A experimental design was used to determine the effects of therapeutic exercise. The single-subject was a 27-year-old male, who presented with knee joint valgus deformity. Corrective exercise program was performed for 40 min/day twice a week for 12-week. Range of motion (hip flexion, extension, abduction, adduction, internal rotation, and external rotation), lower limb alignment test (Q-angle, rear foot alignment, and leg length), standing anterior-posterior radiographs (neck shaft angle and knee joint space), and quadriceps muscle activity of both lower limbs were measured before (A 1), after 6 weeks (B 1) and after 12-weeks (B 2) of corrective exercise and after 6 weeks of exercise completion (A 2). RESULTS: Hip range of motion increased in all directions of both sides at B 2 and A 2 compared to at A 1. Q-angle of both side and leg length discrepancy decreased at B 2 and A 2 compared to at A 1. Neck shaft angle and knee joint space of both sides improve at B 2 and A 2 compared to at A 1. Quadriceps of both side muscle activities improved at B 2 and A 2 compared to at A 1. CONCLUSION: We demonstrated that corrective exercise increases range of motion, and improves lower limb alignment and muscle activity in a patient with knee joint valgus deformity.

Background: Landing from a step or stairs is a basic motor skill but high incidence of lateral ankle sprain has been reported during landing with inverted foot. Objects: This study aimed to investigate the effect of landing height and visual feedback on the kinematics of landing and supporting lower limbs before and after the touch down and the ground reaction force(GRF)s. Methods: Eighteen healthy females were voluntarily participated in landing from the lower (20 cm) and the higher (40 cm) steps with and without visual feedback. To minimize the time to plan the movement, the landing side was randomly announced as a starting signal. Effects of the step height, the visual feedback, or the interaction on the landing duration, the kinematic variables and the GRFs at each landing event point were analyzed. Results: With eyes blindfolded, the knee flexion and ankle dorsiflexion on landing side significantly decreased before and after the touch down. However, there was no significant effect of landing height on the anticipatory kinematics on the landing side. After the touch down, the landings from the higher step increased the knee flexion and ankle dorsiflexion on both landing and supporting sides. From the higher steps, the vertical GRF, anterior GRF, and lateral GRF increased. No interaction between step height and visual feedback was significant. Conclusion: Step height and visual feedback affected the landing limb kinematics independently. Visual feedback affected on the landing side while step height altered the supporting side prior to the touch down. After the touch down, the step height had greater influence on the lower limb kinematics and the GRFs than the visual feedback. Findings of this study can contribute to understanding of the injury mechanisms and preventing the lateral ankle sprain.

The purpose of this report was to describe the gait pattern and parameters of the complicated bilateral amputee with right transtibial and left tarsometatarsal amputation. Using a Vicon 370 three dimensional gait analysis system, the gait analysis was performed at pre and post-test. Treadmill Training with 15 degree, incline was practiced for 8weeks, 3times per week. In linear parameters, the Velocity, Stride length and Single limb support were increased than pre-test. but Cadence and Double limb support were less post-test than pre-test. In kinematics, the maximal pelvic tilt angle showed right side $21.87^{\circ}$, left side $20.67^{\circ}$ at pre-swing phase, and decreased as compared with pre-test. Especially, the inimal hip flexion angle showed right side $-6.83^{\circ}$, left side $1.52^{\circ}$ at pre-swing phase and increased as compared with pre-test. The maximal knee flexion angle disclosed right side $2.66^{\circ}$, left side $21.71^{\circ}$ at stance phase, and decreased as compared with pre-test. In kinetics, the hip extension moment on initial contact stage was right side 0.938NM/Kg, left side 0.09NM/Kg, which was impaired compared with normal person.

Objectives: The objective of this study was to identify the differences in obesity rates among people with and without disabilities, and evaluate the relationship between obesity rates and the existence of disabilities or characteristics of disabilities. Methods: Mass screening data from 2008 from the National Disability Registry and National Health Insurance (NHI) are used. For analysis, we classified physical disability into three subtypes: upper limb disability, lower limb disability, and spinal cord injury. For a control group, we extracted people without disabilities by each subtype. To adjust for the participation rate in the NHI mass screening, we calculated and adopted the weight stratified by sex, age, and grade of disability. Differences in obesity rates between people with and without disabilities were examined by a chi-squared test. In addition, the effect of the existence of disabilities and grade of disabilities on obesity was examined by multiple logistic regression analysis. Results: People with disabilities were found to have a higher obesity rate than those without disabilities. The obesity rates were 35.2% and 35.0% (people with disabilities vs. without disabilities) in the upper limb disability, 44.5% and 34.8% in the lower limb disability, 43.4% and 34.6% in the spinal cord injury. The odds for existence of physical disability and grade of disability are higher than the nondisabilities. Conclusions: These results show that people with physical disability have a higher vulnerability to obesity.
