The purpose of this study was to evaluate the ankle joint movements and moments during Plie-Releve between wearing a toe-shoes and barefoot. These experimental subjects were 6 females, who had no skeletal muscular disease. They were performed Plie-Releve with wearing a toe-shoes and barefoot. Repeated t-test is applied to get the difference of ankle joint movements and moments significant level of each experiment is set as α=.05. 1. There were significant between wearing a toe-shoes and barefoot on plantar/dorsi flexion, internal/external rotation with range of ankle joint movement. 2. There were significant between wearing a toe-shoes and barefoot on extension inversion, internal rotation angular velocity with ankle joint. 3. There were significant between wearing a toe-shoes and barefoot on dorsi flexion and external rotation moments with ankle joint. In conclusion, when subjects perform the Plie-Releve at wearing a toe-shoes, ankle becomes more range of joint angular displacements and maximum angular velocities. In addition, these kinematics factors occurred that made an unstable ankle joint. So, ankle joint moments at wearing a toe-shoes occurs larger as well as ankle joint moments at unwearing a toe-shoes, which supports the argument that protective muscle-skeletal training of ankle joint is performing to prevent stable the ankle joint from acting ankle joint at Plie-Releve.

안병주(Byeongju An) 한국방사선학회 2013 한국방사선학회 논문지 Vol.7 No.2

발목 병변을 관찰하는 단순 방사선촬영은 여러 가지가 있다. 그 중에서 Ankle Broden법은 발꿈치뼈(Calcaneus)및 발목뼈(Ankle Joint)의 결합상태와 발목뼈의 발꿈치뼈 골절(Calcaneus Fracture), Subtentaculum Tali Frature를 관찰하기 위하여 촬영을 한다. 이 촬영법은 전ㆍ후면과 측면뿐 아니라, 사면 상(oblique view)이나 축 상(axial view)의 촬영을 하며 잦은 부상이 발생하는 목말뼈ㆍ 발꿈치뼈간, 발꿈치뼈ㆍ발배뼈간 결합상을 보기 위해 주로 촬영을 한다. 본 연구는 석고처치 환자들은 발목관절이 영상에 잘 묘출되기가 어렵기 때문에 발목뼈 사이의 관계 및 연부조직의 구조적 변화와 Subtalar joint, Calcaneus Fracture, Subtentaculum Tali Frature에 따른 목말뼈ㆍ발꿈치뼈의 골 결합 (talocalcaneal coalition)을 관찰하기 위한 Harris-Beath View(30°∼55°) 촬영 시 평가에 유용한 발목뼈의 결합상을 얻을 수 있는 각도를 알아보고자 하였다. 연구의 진행은 40명의 환자에게서 획득한 영상을 평가하였으며, 평가결과 25°의 촬영상은 목말밑 관절(subtalar joint)이 열려져 분리되지 않았고 또한, Subtentaculum Tali Frature에 중복되어 보였다. 30°의 촬영상은 발꿈치뼈 골절(Calcaneus Fracture), Subtentaculum Tali Frature, 목말밑관절(subtalar joint)과 후방 관절면의 앞부분이 가장 잘 나타나고 Calcaneo Navicularcoalition, Talocal Canealcoalition, Naviculo Cuneiform coalition의 결합상태가 명확하게 보였다. 35°의 촬영상은 목말밑관절(subtalar joimt), 목말뼈(talus), 발뒤꿈치뼈의 뒤쪽관절면이 명확하고 발목발꿈치관절(talocalcaneal joint)의 분리정도가 좋고 발목뼈굴(sinus tarsi)이 넓게 나타나며 좋은 평가가 되었다. 45°영역에서는 연부조직과 석고 분리를 판별할 수 있었고 가쪽복사와 뼈 밀도가 명확하게 보였다. 35°에 비해 발꿈치뼈(Calcaneus)이 분리되었지만 영상이 왜곡되어 보였다. Calcaneus, Subtentaculum Tali Frature는 25°에서 1.20±0.414, 30°에서는 2.47±0.516, 35°에서는 2.87±0.352, 45°에서는 2.27±0.458로 나타났고 통계적으로 유의한 차이가 나타났다(p<0.05). 왜곡의 정도를 포함시키면 30°영역의 왜곡이 적게 나타났고, 40°영역은 심한 왜곡현상을 보였다. 따라서 Ankle(Broden)촬영에서 30∼35°상이 가장 좋은 영상이었으며, 30∼40°상에서는 Calcaneus Fracture, Subtentaculum Tali Frature의 진단에 가장 좋은 영상을 묘출하였다. There is an Ankle Oblique(Broden’ low) as an examination for the patient whose ankle was encased in orthopedic plaster. Some types of Ankle Joint coalition - Calcaneonavicular coalition, Talocalcaneal coalition and Naviculocuneiform coalition. This study is focused on the relation between Ankle Joints and the structural change of soft tissues, also finding the most proper angle to obtain good images of Ankle Joint from the patient who wore a plaster on his ankle, when we x-ray with Harris-Beath View(30°∼55°) - for observing Subtalar joint, Calcaneus Fracture, Subtentaculum, Tali Fracture and Talocalcaneal coalition. We intend to get the angle which makes us achieve the good image that shows Calcaneus Fracture, Subtentaculum, and Tali Fracture by changing internal angles of the patient’s ankle. We evaluated the images obtained from 51 patients with PACS monitor. The result of the evaluation, subtalar joint was not seperated but opened, and Subtentaculum Tali Fracture was seen overlaid. at the angle 30, we could observe Calcaneus Fracture, Subtentaculum Tali Frature and the front part of behind side of subtalar joint well. And Calcaneo Navicularcoalition, Talocal Canealcoalition, Naviculo Cuneiform coalition condition were clearly seen at that angle. At the angle 35, we could achieve the clear images of subtalar comminuted fracture, talus, the behind joint of heel bone and get the high definition image on the degree of talocalcaneal joint separation. In addition to, We could obtain the good wide image of Sinus Tarsi. At the area of 45, We can distinguish the soft tissues from gyps separation. The outer-talus and density of the bone were definitely seen and Calcaneus is more separated than that of at the angle of 35, but this image is distorted. Calcaneus, Subtentaculum Tali show 1.20±0.414 at the angle 25, 2.47±0.516 at the angle 30, 2.27±0.458 at the angle 45. This difference is statistically meaningful. (p<0.05). Including the degree of distortion, The distortion appears less at the area of 30° but at the area of 40, there is heavy distortion. So, We could get the best image for making a diagnosis. At the 30∼35° degree for X-raying ankle. and at the 30∼40° for Calcaneus Fracture, Subtentaculum Tali Fracture.

Maiko Goto,Yasuko Shiga,Yasuyoshi Mizuno,Mitsuko Nakamura,Han Suk Jung 한서대학교 보완대체의학연구소 2014 Research Journal of Complementary and Alternative Vol.- No.5

The study conducted by Ishida et al. showed that improvement in muscle strength increases exercise capacity and that the direction of exercise has an influence on muscle activity. We studied the effect of the change in range of motion in plantar flexion and dorsiflexion of the ankle joint on exercise capacity. Either left or right superior tibiofibular joint that had the narrower range of motion was adjusted, and the range of motion in plantar flexion and dorsiflexion of the ankle joint were measured with a goniometer and compared before and after the adjustment. The distance of standing broad jump before and after the adjustment were compared. We found that the range of motion in the ankle joint was limited by the limitation of the range of motion in the tibiofibular joint. The results showed that increase in the range of motion in the ankle joint significantly increased the distance of standing broad jump. Increase in the range of motion m the ankle joint, especially adjustment of the tibiofibular joint, is effective to improve exercise performance.

본 연구의 목적은 최적화 기법을 이용한 보행 시 발목 관절의 동역학적 해석에 근거하여 실제 인간의 보행 시 발목관절에서 발생하는 접촉력으로 추정함으로써 생체역학적 및 임상적인 관점에서 평가 할 수 있는 방법론 제시에 그 목적이 있다. 이러한 연구의 목적을 달성하기 위하여 본 연구 대상자들은 근골격계의 질환이 없는 정상인 집단 10명을 선정하였으며, 보행 동작 시 최적화 기법을 이용한 발목 관절의 근골격계 해석은 RHS(right heel strike)에서 RTO(right toe off)까지만 분석하였다. 최적화 기법을 이용한 발목 관절의 근골격계의 해석에서 중추신경계의 생리적 근육 이용 전략에 근거하여 인간의 동작은 최적화되며, 동작 시 최소의 근육 동원이 수행될 것이라는 가정하고, 발목 관절은 3자유도를 가진 복합관절의 복합(complex)관절로 정의하였다. 이와 같은 발목 관절의 정의와 가정에 의해서 인체 모델링을 설정하였고 운동학적 데이터 산출을 위한 3차원 좌표 및 운동역학적 데이터인 지면반력 데이터 산출을 위하여 Kwon3d와 KwonGRF 프로그램을 이용하였으며, 보행 시 발목 관절에 작용하는 11개 근육의 힘들을 고려하여 발목 접촉력은 matlab(Version6.5) 프로그램으로 프로그래밍하였다. 산출된 발목관절 접촉력의 자료는 평균값을 이용하여 얻어진 결론은 다음과 같다. 인간을 대상으로 발목관절의 접촉력을 산출하는 방법 중 동역학 접근법의 근거아래 발목관절에 작용하는 근육의 힘들을 최적화하여 얻어진 접촉력은 선행연구들에서 얻어진 결과와 같은 결과를 보였을 뿐만 아니라 좌ㆍ우, 전ㆍ후 전단력도 평가 할 수 있는 발목관절 모델링과 프로그램 방법론을 제시하였다. 본 연구에서 제시된 DLO 방법은 실제 계산되는 시간이 다른 선행연구들에서 제시된 방법들과 비교하여 보았을 때 매우 효과적인 방법이라 할 수 있다. 그러므로 인간의 보행 시 발목 관절의 임상적 측면을 생체역학적 관점으로 평가 할 수 있는 방법으로 이용될 것으로 기대된다. The purpose of this study was to evaluate the clinical applicability throughout dynamically analysis of the ankle joint used of optimization. To do this, the normal group included 10 participants who had no skeletal muscular disease. On the study, the DLO(Double Linear Optimization) method during walking used of skeletal muscular interpretation analyzed from RHS(right heel strike) to RTO(right toe off). Human walking movement is optimized based on physiological muscle controlled by the central nervous system, and it was assumed that minimum number of skeletal muscle would be mobilized during the movement. The ankle joint was defined 3 free-degree ball-and-socket complex joint. Body modeling was set up based on the definition and assumption of the ankle joint. Kwon3d and KwonGRF program were used for 3d result of kinematic data and results of exercise kinetic data. Matlab(version 6.5) was employed to analyze osculating ability used of mean values. These data resulted in the followings: Dynamically kinetic interpretation of ankle skeletal muscular modeling on 3 free-degree, 11 muscles during normal subjects` walking used of optimization method. Because the DLO technique used in the study has been reported to influence to an accuracy of real experimental data, each variable, such as angle variables, joint repulsive moment, was quantitatied by the previous experiment to control possible errors. Individual powers of 3 free-degree 11 muscles were calculated by the skeletal muscle modeling used of kinematic and kinetic factors of ankle joint computed by the experiment. However, The important result from the study was the interpretation of osculating ability of the ankle joint. Even though this study was finished shortly when compared to the previous studies, the same results were observed. Furthermore, this study tested the four direction share force. Therefore, this study provided practical and computationally inexpensive method of estimating in vivo quantities ankle joint contact forces. Thus, this method may be used on the clinical area to verify effects of biomechanical to evaluate ankle joint for human walking.

윤현(Hyun Yun) 한국응용과학기술학회 (구.한국유화학회) 2020 한국응용과학기술학회지 Vol.37 No.2

본 연구의 목적은 유도 허벅다리걸기 기술 발휘 시 발목 관절의 테이핑 처치가 하지 관절과 압력중심(COP, center of pressure)에 미치는 영향을 분석하는데 있었다. 대학 유도 선수 20명(연령, 20.9±0.8세; 신장, 168.6±7.4cm; 체중, 73.5±11.6kg; 신체질량지수, 25.7±2.6kg/m 2 )이 참여하였으며, 발목 관절 테이핑 처치 전과 후의 2가지 조건에서 허벅다리걸기 기술 발휘 시 지지다리 관절의 각도와 압력중심 요인을 분석하여 다음의 결과를 도출하였다. E2(t=2.411, p=.027) E4(t=2.388, p=.029)시점에서 발목 관절의 각도는 테이핑 처지 전에 비해 처치 후 발목의 각도가 통계적으로 적은 수치를 나타내었고, E2(t=-2.343, p=.032) E3(t=-4.531, p=.000)시점에서 힙 관절의 각도는 통계적으로 크게 나타났다. 그리고 발목 관절 테이핑 처치 후 좌·우의 COP 이동은 상대를 메치는 P3 국면에서 통계적으로 크게 나타났으 며(t=2.670, p=.016), 전·후의 COP 이동은 상대의 무게 중심을 기울이는 P1 국면에서 통계적으로 적은 수치를 나타내었다(t=2.846, p=.011). 그러므로 허벅다리걸기를 특기로 사용하는 유도 선수들은 발목 관절 테이핑으로 인해 발생하는 지지관절의 운동 기능과 COP의 이동범위를 고려하여 사용하는 것에 대하여 제안하고자 한다. The purpose of this study was to analyze the effect of ankle joint taping treatment on lower extremity joint and center of pressure(COP) factors during the Uchi-mata. Twenty college judo athletes (age, 20.9 ± 0.8 years; height, 168.6 ± 7.4cm; weight, 73.5 ± 11.6kg; body mass index, 25.7 ± 2.6kg/m 2 ) participated, and two types before and after ankle joint taping treatment when the during the Uchi-mata was exhibited under conditions, the angle and COP factors of the support leg joints were analyzed to show the following results. At the time of E2 (t = 2.411, p = .027) E4 (t = 2.388, p = .029), the ankle joint angle was statistically less after the treatment than before the taping treatment, and E2 (t = -2.343, p = .032) At E3 (t = -4.531, p = .000), the angle of the hip joint was statistically large. And after the ankle joint taping treatment, the medial/lateral COP movement after the ankle joint taping treatment was statistically large in the P3 phase of throwing the opponent (t = 2.670, p = .016), and the anterior/posterior COP movement showed a statistically small number in the P1 phase where the opponent was tilted (t = 2.846, p = .011). Therefore, it was suggested that judo athletes who use thighs as a special technique should be used considering the movement function of the support joint and the range of movement of the COP caused by tapping of the ankle joint.

Design of the Control Software for a Biped Robot

Lee, Keon-Young 광운대학교 신기술연구소 1997 신기술연구소논문집 Vol.26 No.-

인간의 발목 관절의 특성을 모사한 기구적 제약 조건과 스프링으로 구성된 발목 관절을 갖는 두발 로보트의 보행을 다룬다. 본 연구에서 제시되는 순응성 발목 관절을 갖는 로보트는 바닥 면이 고르지 않은 경우에도 발바닥과 바닥 면과의 접촉 상태를 좋게 한다. 이는, 로보트의 무게중심 파악을 위한 발바닥 힘센서 설치를 용이하게 하며, 발목 관절을 구동하기 위한 별도의 모터가 필요 없어 다리의 중량이 가벼워져 로보트의 보행 속도를 증가시키는데 유리하다. 그러나, 발목 관절의 순응성은 원하는 보행 자세를 취할 경우 힘을 낼 수 가 없어 오히려 보행의 장애 요인이 된다. 이를 극복하기 위한 방법인 관성력을 이용한 동적 보행과 허리나 무릎 관절의 자세 교정을 통한 간접적인 발목 관절 구동 법이 본 연구에서 제시된다. 제시된 제어기의 타당성의 검토를 위하여 SD-2 Biped 로보트 (미국 Ohio State Univ. 소재)의 수학적 모델에 대한 시뮬레이션 결과가 제시된다. Control of a biped robot which has compliant ankle joints is dealt in this paper. Simulated version of a human ankle joint is built using springs and mechanical constraints, which gives a flexibility of joint and compliance against the touching ground. The biped robot with compliant ankle joints proposed here gives a good contact between its sole and the ground and makes foot landing soft. As a result, installing force sensors for measuring the center of gravity of the biped becomes easier. A motor to drive an ankle joint is not needed which makes legs light. However, the control problem becomes more difficult because the torque of the ankle joint to put the biped in a desired walking gait cannot be provided from the compliant ankle joint. To solve this problem, we proposed a dynamic gait modification method by adjusting the position of a hip joint. Simulation results for the mathematical model of the SD-2 biped in the Ohio State University are given to show the validity of the proposed controller.

이재우,박준성,임영태,권문석 한국응용과학기술학회 2020 한국응용과학기술학회지 Vol.37 No.3

The purpose of this study was to analyze the correlation between passive ankle movement range and knee joint kinetic variables during squat movement. In this study, a total of 27 subjects participated in this study, 19 men and 8 women, who had no history of the musculoskeletal system of the lower extremity. To verify the correlation between the ankle joint flexibility and the knee joint kinetic variables during deep squat, it was performed pearson’s correlation coefficientand variables showing statistically significant correlation were performed by simple regression analysis at a significant level of α .05. Through this study, the relationship between the peak joint moment and joint reaction force factors that determine ankle joint flexibility and knee joint pressure was confirmed. Therefore, when applying an exercise that can generate a lot of load on the knee joint such as deep squats during strength training, checking the degree of flexibility of the ankle joint among physical characteristics to the individual may reduce the stability of the body and the risk of injury to the knee joint. It is expected to be helpful in setting the intensity of exercise that can be done. 연구의 목적은 딥 스쿼트 동작 시 발목 관절 유연성이 무릎 관절의 운동역학적 요인들간의 관련성을 분석하는데 있었다. 본 연구는 최근 1년간 하지 근골격계 병력이 없는 성인 남성 19명과 여성 8 명이 연구대상자로 참여하였다. 딥 스쿼드 시 발목 관절 유연성과 하지 관절의 운동역학적 요인들과 상관 관계를 검증하기 위해 pearson의 적률상관계수(pearson’s correlation coefficient)를 이용하였고(SPSS 24.0, Armonk, NY, USA), 통계적으로 유의미한 상관성을 나타낸 변인들은 단순회기분석(simple regression analysis)을 실시하였으며, 유의 수준은 .05로 설정하였다. 본 연구를 통해 발목 관절 유연성과 무릎 관절의 압력을 결정하는 최대 관절모멘트와 관절반발력 요인들 간의 관련성을 확인할 수 있었다. 그러므로 근력 트레이닝 시 딥 스쿼트와 같은 무릎 관절에 많은 부하를 발생시킬 수 있는 운동을 적용할 때 개인에 신체적 특성 중 발목 관절의 유연성의 정도를 확인하는 것은 신체의 안정성과 무릎 관절의 상해 위험성을 감소 시킬 수 있는 운동 강도를 설정하는데 도움이 될 수 있을 것으로 기대한다.
