  • Objective: The aim of this study is to evaluate the accuracy and reliability of Spine-Pelvis Monitor(SPM) that was developed to measure 3-dimensional motion of spine and pelvis using tilt sensor and gyro sensor. Background: The main cause of low back pain is very much associated with the task using the low back and pelvis, but no measurement technique can quantify the both spine and pelvis. Method: For testing the SPM, 125 angles from three anatomical planes were measured three times in order to evaluate the accuracy and reliability. The accuracy of SPM in measuring dynamic motion was evaluated using digital motion analysis system. The motion pattern captured by two measuring methods was compared with each other. In result, the percentage error and Cronbach coefficient alpha were calculated to evaluate the accuracy and reliability. Results: The percentage error was 0.35% in flexion-extension on sagittal plane, 0.43% in lateral bending on coronal plane, and 0.40% in twisting on transverse plane. The Cronbach coefficient alpha was 1.00, 0.99 and 0.99 in sagittal, coronal and transvers plane, respectively. Conclusion: The SPM showed less than 1% error for static measurement, and showed reasonably similar pattern with the digital motion system. Application: The results of this study showed that the SPM can be the measuring method of spine pelvis motion that enhances the kinematic analysis of low back dynamics.

  • The purpose of this study was to analysis of pelvis and lower extremity using orientation angles during a developpe a la seconde. Data were collected by Kwon3D program. Two females professional modem dancer were participated in this experiment. Subjects performed a developpe a la seconde in meddle heights(about 90 dog.) The results were as follows. The orientation angles of pelvis were, in most cases, caused by the movement of trunk and thigh. It was restricted the movement of pelvis within narrow limits because the movement of pelvis was very important to lower extremity alignment. The orientation angle of shank against thigh showed a change of angle about $3-6^{\circ}$ in internal external rotation. The orientation angle of foot against shank showed a change of angle about $6-7^{\circ}$ in internal external rotation.

  • Although the progress in bipedal walking is impressive in recent years, biped robots still require very high torque and can walk only for a short time interval with their internal batteries. Therefore, further research needs to be carried out to enhance walking efficiency of these robots. In order to achieve this goal, we attempt to imitate human walking with pelvis and waist joint rotations in the frontal plane. In order to investigate the effect of the pelvis and waist joint rotations in the frontal plane motion, we study the frontal plane model with a triangular structure made up of a waist joint and two hip joints. Through simulation, we show that the pelvis rotation can reduce the maximum torque and the control effort, and the waist joint rotation can reduce the trunk sway caused by the pelvis rotation. The combination of these two rotations makes the bipedal walking in the frontal plane more efficient.

  • 정상인의 골반 정면 영상을 계측하여 성별과 나이에 따라 골반의 형태적 차이가 있는지 알아보고, 나이에 따라 골반의 변위가 발생하는지 남녀 구분하여 분석하였다. 정상인 총 382명(남성 194명, 여성 188명)을 대상으로 골반정면 단순촬영을 시행하여 PACS 영상에서 최대골반너비(MPB), 엉덩뼈너비(SB), 위골반공가로지름(TD), 넙다리뼈머리사이거리(DFH)를 측정하여 골반계측을 시행하였다. 성별에 따른 골반 계측 차이는 평균비교분석, 나이와 계측치의 관계는 상관분석을 하였다. 골반의 변위는 ANOVA test를 시행하였다. 최대골반너비는 성별에 따른 차이는 없었으나, 남성 엉덩뼈너비의 평균은 97.76 mm이었고, 여성은 102.00 mm으로 여성에서 엉덩뼈너비가 유의하게 큰 것으로 나타났다. 위골반공가로지름의 평균은 남성 138.00 mm, 여성 149.79 mm이었고, 넙다리뼈머리사이거리는 남성 141.94 mm, 여성 150.39 mm로 나타났고, 위골반공가로지름과 넙다리뼈머리사이거리는 여성에서 유의하게 더 큰 것으로 나타났다. 나이와 골반계측에서는 넙다리뼈머리 사이거리가 남성(r = -0.280)과 여성(r = -0.207)에서 각각 음의 상관관계가 있었다. 나이에 따른 골반 변위는 남성 50대에서 변위가 크게 나타났고, 여성은 60대, 70대에서 변위가 크게 나타났다. 엉덩뼈너비와 위골반공가로지름, 넙다리뼈머리사이거리는 남성보다 여성에서 더 크게 나타났고, 골반의 크기가 큰 사람은 최대골반너비와 엉덩뼈너비, 위골반공가로지름, 넙다리뼈머리사이거리도 컸다. 나이가 많을수록 변위가 크게 나타났고, 이는 노화의 과정이라고 판단된다.

  • Alignment of the hip joint and pelvis affects it's weight-bearing capabilities as well as the motion available at the joints. The normal hip joint is well designed to withstand the forces that act through and around it, assisted by the trabecular systems, cartilagious, muscles, and ligaments. Alterations in the direction or magnitude of forces action around the injury and degenerative changes. The integration of motion of the pelvis with motion of the vertebral column not only increases the ROM available to the total column but also reduces the amount of flexibility required of the lumbar lesion. In any instance in which there is normal or abnormal pelvic motion during weight hearing and the head must remain upright, compensatory motions of the lumber spine will occur if available. The motions that occur at the hip, pelvis, and lumbar spine during forward trunk bending with the motions that occur during anterior and posterior tilting of the pelvis in the erect standing postion.

  • Purpose. This study was to investigate that the adjustment of Chiropractic pelvis method have effect on body balance and improvement people who has some problem in their daily life. Methods. With 20 students of experiment group and 20 students of compare group who has cervical syndrome, experiment group has adjustment of chiropractic pelvis 2 times a week for 4 weeks, the other group who didn't take any action. Results. As a result, center of body of experiment group wasn't improved relations between left and right statistically. But the relations between front and back of center of body increased statistically, cross analysis relations between short leg and center of body increased statistically. Conclusions. As a conclusion, experiment group with the front of center of body was improved 12.88% average of center of body. Experiment group with back of center of body was improved 13.84% average of center of body. This result come to the conclusion that chiropractic pelvis adjustment help the front and back of body balance.

  • A 12-year-old dog was evaluated for depression and anorexia. The results of complete blood count and serum biochemistry were normal. Survey radiographs revealed markedly enlarged right kidney and abdominal ultrasound showed a renomegaly and hydronephrosis filled with mixed echogenic fluid. Primary renal tumor was suspected in this dog. Nephroureterectomy of the right kidney was performed, and no regional metastases have been identified. Transitional cell carcinoma (TCC) arising from renal pelvis accompanied hydronephrosis of the right kidney was diagnosed on histology. TCC usually affects trigone of the bladder, and renal origin of TCC is a very rare finding in dogs. This is the first case report to present the clinical features, diagnostic imaging findings and histopathological characteristics of a dog with TCC originating from the renal pelvis in Korea.
