Purpose: The transverse abdominis and themultifidus muscle are located in the core. They surround one's trunk and help in body stabilization. Specifically, they control spine articulation to maintain posture and balance. Therefore, weakened deep muscle in the trunk may cause spinal malalignment. This study aims to compare the correlation between the thickness of the transverse abdominis and the multifidus muscle and the spine alignment among college students in their 20s. Methods: This study measured the thickness of the transverse abdominis and the multifidus muscle of 42 healthy college students in their 20s using ultrasonic waves. The thickness of the muscle was measured for the length of the cross-section except for fascia. The thickness of the left and right muscles was measured, and the mean value was calculated. As the thickness of the transverse abdominis can increase because of pressure during exhalation, it was measured at the last moment of exhalation. Spinal alignment was measured by the kyphosis angle, lordosis angle, pelvic tilt, trunk inclination, lateral deviation, trunk imbalance, and surface rotation using Formetric III, which is a three-dimensional imaging equipment. They were measured for three times, and the mean values were calculated. The general characteristics of the subjects were analyzed using descriptive statistics. The correlations between each factor were analyzed using Pearson's correlation analysis. Results: The transverse abdominis showed asignificant correlation with trunk inclination (p<.05). The multifidus muscle showed a significant positive correlation with pelvic tilt and a negative correlation with surface rotation (p<.05). Conclusion: The thickness of transverse abdominis and the multifidus muscle appears to influence spinal alignment. Specifically, the multifidus muscle, which plays an important role on the sagittal plane, influences surface rotation, thus making it an important muscle for scoliosis patients. Therefore, a strengthening training program for the transverse abdominis and the multifidus muscle is necessary according to specific purposes among adults with spinal malalignment.

Background: Individuals with spinal cord injury (SCI) rely on their upper limbs for body-lifting activity (BLA). While studies have examined the electromyography (EMG) and kinematics of the shoulder joints during BLA, no studies have considered foot position during BLA. Objects: This study compared the effects of different foot positions during BLA on the shoulder muscle activities, peak plantar pressure, knee flexion angle, and rating perceived exertion in individuals with SCI. Methods: The study enrolled 13 mens with motor-complete paraplegic SCI, ASIA (American Spinal Injury Association) A or B. All subjects performed BLA with the feet positioned on the wheelchair footrest and on the floor independently. Surface EMG was used to collect data from the latissimus dorsi, pectoralis major, serratus anterior, and triceps brachii. The peak plantar pressure was measured using pedar-X and the knee flexion angle with Image J. Borg's rating perceived exertion scale was used to measure the physical activity intensity level. The paired t-test was used to compare the shoulder muscle activities, peak plantar pressure, knee flexion angle, and rating perceived exertion between the two feet positions during BLA. Results: The activity of the latissimus dorsi, pectoralis major, serratus anterior, and triceps brachii and rating perceived exertion decreased significantly and the peak plantar pressure and knee flexion angle increased significantly when performing BLA with the feet positioned on the wheelchair footrest compared with on the floor (p<.05). Conclusion: These findings suggest that individuals with SCI may perform BLA with the feet positioned on the wheelchair footrest for weight-relief lifting to decrease the shoulder muscle activities and the rating perceived exertion and to increase the peak plantar pressure and the knee flexion angle.

PURPOSE: This study was conducted to assess the effects of local vibration on ankle plantarflexion spasticity and clonus in patients with spinal cord injury. METHODS: The subjects were 14 inpatients with complete or incomplete spinal cord injury (SCI) whose scores were higher than 1 on the Modified Ashworth Scale (MAS) and Spinal Cord Assessment Tool for Spastic Reflexes (SCATS) scale of paraplegia. A randomized single-blind cross-over design was used. Vibration treatment involved a single application of vibration for 10 min in the sitting position, and placebo treatment involved the patient remaining in the sitting position for 10 min. One day after treatment, vibration and placebo treatments were crossed over. Spasticity was measured by using the MAS, and resistance force, by using a hand-held dynamometer; clonus was gauged by using the SCATS scale and clonus burst duration. Additionally, the burst maximal frequency and voluntary ankle dorsiflexion angle of the triceps surae were measured. RESULTS: The application of vibration treatment in the sitting position significantly reduced the MAS scores and resistance force, but significantly increased the dorsiflexion angle of the ankle joint (p<0.05). Furthermore, the vibration treatment diminished the clonus burst duration and SCATS score significantly (p<0.05). Although it reduced the burst maximal frequency of the lateral gastrocnemius and medial soleus, this was significant only for the lateral gastrocnemius. The placebo treatment did not significantly affect any of the test parameters. CONCLUSION: Vibration treatment in the sitting position was effective in cases of spasticity and clonus caused by SCI.

본 연구는 경추 CT 검사 후에 영상을 재구성하는 방법으로, 사위 관상면(oblique coronal) 재구성 각도에 따라서 신경공 골성 협착을 가장 잘 표현할 수 있는 재구성 각도를 제시하고자 한다. 경추의 정중시상면과 구추관절에서 척수 중심을 지나는 선을 그어 만들어지는 각도를 측정하였다. 신경공에서 척수 중심을 지나는 선을 그어, 정중시상면과 이루는 각도를 측정하여 비교하였다. 경추 4-5 레벨에서는 평균 9.2°, 경추 5-6 레벨에서는 평균 9.9°, 경추 6-7 레벨에서는 평균 8.4° 로 구추관절각보다 돌기사이관절각이 크게 측정되었으며, 통계적으로 평균에 유의한 차이가 있었다(p<0.01). 또한, 하부 경추로 갈수록 각도가 증가하는 것을 알수 있었다. 하부 경추(C5-6, C6-7)의 신경공과 척수 중심이 이루는 각은 55~60° 사이이며, 여기에 90°가 되도록 사위 관상면 영상을 재구성하면 신경공협착 정도가 잘 관찰된다. 기존 CT 스캔 영상을 이용한 재구성 영상이므로 추가적인 방사선 피폭을 받지 않으면서, 경추 신경공 골성 협착을 진단하는데 큰 의의가 있다.

Objectives : Thoracolumbar burst fractures(TBLF) result in not only compressive deformity of vertebral body but also spinal cord compression by bony fragments. Many thoracolumbar burst fractures demand both anterior decompression and intervertebral fusion. Most of spinal surgeons use anterior instrumentation for anteior intervertebral bony fusion. The use of Z-plate has been increased recently, however there has been only a few reports regarding its clinical long-term strength. We studied nineteen patients with TBLF to find out the long-term stability of Z-plate. Methods : We have operated 19 patients from March 1996 to August 1998. They were treated with anterior decompression through either a transthoracic, retroperitoneal extrapleural or retroperitoneal approach. Retropulsed bony fragments were removed completely by corpectomy. Iliac bone graft was used for interbody fusion in all of the cases. They were evaluated by plain X-ray films including flexion and extention lateral films. Cobbs angle was used to evaluate kyphotic and lateral wedging deformity. Results : Burst fractured sites were T11 in two, three T12, nine L1, and five L2. Mean follow-up duration was fifteen months. Preoperative average kyphotic angle was 23.7 degree. Immediate postoperative kyphotic angle was 10.2 degree. Follow-up resluts of average kyphotic angles revealed 14 degrees. Four patients(21%), including two spinal 3-column injury, showed increasement of kyphotic angle more than 5 degree or breakage of intrumentation. Two patients showed the difference of kyphotic angle more than 3 degree. Five patients(26%) revealed lateral wedging deformity more than 3 degrees. Postoperative complications were two meralgia parestheticas, one pulmonary atelectasis and two donor site infections. Four of the eight patients, who initially showed incomplete spinal cord deficits, were nerologically improved by Frankel's grade. Conclusion : Z-plate fixation and iliac bone graft after anterior decompression in thoracolumbar burst fractures is a safe and easy method. Immediate postoperative results revealed excellent correction of posttraumatic kyphosis, but long-term follow-up evalution showed insufficient strength. Therefore we believe that use of Z-plate should be carefully decided, especially in the case of large lumbar fracture or 3-column injury.

Objective : Thoracoscopic spinal surgery provides minimally invasive approaches for effective vertebral decompression and reconstruction of the thoracic and thoracolumbar spine, while surgery related morbidity can be significantly lowered. This study analyzes clinical results of thoracoscopic spinal surgery performed at our institute. Methods : Twenty consecutive patients underwent video-assisted thoracosopic surgery (VATS) to treat various thoracic and thoracolumbar pathologies from April 2000 to July 2006. The lesions consisted of spinal trauma (13 cases), thoracic disc herniation (4 cases), tuberculous spondylitis (1 case), post-operative thoracolumbar kyphosis (1 case) and thoracic tumor (1 case). The level of operation included upper thoracic lesions (3 cases), midthoracic lesions (6 cases) and thoracolumbar lesions (11 cases). We classified the procedure into three groups: stand-alone thoracoscopic discectomy (3 cases), thoracoscopic fusion (11 cases) and video assisted mini-thoracotomy (6 cases). Results : Analysis on the Frankel performance scale in spinal trauma patients (13 cases), showed a total of 7 patients who had neurological impairment preoperatively : Grade D (2 cases), Grade C (2 cases), Grade B (1 case), and Grade A (2 cases). Four patients were neurologically improved postoperatively, two patients were improved from C to E, one improved from grade D to E and one improved from grade B to grade D. The preoperative Cobb's and kyphotic angle were measured in spinal trauma patients and were $18.9{\pm}4.4^{\circ}$ and $18.8{\pm}4.6^{\circ}$, respectively. Postoperatively, the angles showed statistically significant improvement, $15.1{\pm}3.7^{\circ}$ and $11.3{\pm}2.4^{\circ}$, respectively(P<0.001). Conclusion : Although VATS requires a steep learning curve, it is an effective and minimally invasive procedure which provides biomechanical stability in terms of anterior column decompression and reconstruction for anterior load bearing, and preservation of intercostal muscles and diaphragm.

목 적 : 비소세포 폐암의 치료용적의 크기가 크거나 폐 용적이 작고, 몸의 정중선(Mid line)에 위치한 경우 척수의 허용선량을 고려한 방사선치료계획에서 폐 선량이 많아지게 되는데, 본 연구는 비소세포 폐암 환자의 3차원입체조형치료(Three dimensional conformal radiotherapy, 3D CRT), 제한된 각도를 이용한 세기변조방사선치료(Intensity modulated radiotherapy, IMRT)와 용적변조회전치료(Volumetric Modulated Arc therapy, VMAT) 치료계획을 각각 적용하여 전체 폐 선량을 비교 및 평가하고자 한다. 대상 및 방법 : TrueBeam STx($Varian^{TM}$, USA) 10 MV 에너지를 이용하여 4명의 환자에 대하여 3D CRT, 제한된 각도를 이용한 IMRT와 VMAT 치료계획을 세우고, 총 선량 66 Gy/30 Fx 처방하였을 때, 선량용적히스토그램(Dose Volume Histogram, DVH)을 이용하여 치료계획용적(Planning Target Volume, PTV), 전체 폐 그리고 척수에 들어가는 선량을 평가하였다. PTV에 대한 처방선량지수(Conformity Index, CI), 선량균질지수(Homogeneity index, HI), 처방선량포함지수(Paddick's Conformity Index, PCI)를 구하고, 폐의 30 Gy 용적($V_{30}$), $V_{20}$, $V_{10}$, $V_5$, 평균선량(Mean dose)을 평가하고, 척수의 최대선량 값을 평가하였다. 결 과 : PTV에 대한 CI, HI, PCI의 평균값은 각각 $0.944{\pm}0.009$, $1.106{\pm}0.027$, $1.084{\pm}0.016$으로 평가되었다. 전체 폐에 대한 첫 번째 환자의 $V_{20}$은 3D CRT, IMRT, VMAT 각각 30.7%, 20.2%. 21.2%, 두 번째 환자의 $V_{20}$은 33.0%, 29.2%. 31.5%, 세 번째 환자의 $V_{20}$은 51.3%, 34.3%. 36.9%, 네 번째 환자의 $V_{20}$은 56.9%, 33.7%. 40%로 제한된 각도를 이용한 IMRT 치료계획에서 가장 낮게 평가되었다. 척수에 대한 최대선량 값은 모두 허용선량 미만으로 평가되었다. 결 론 : 비소세포 폐암의 방사선치료계획에서 3D CRT와 비교했을 때, 제한된 각도를 이용한 IMRT나 VAMT을 이용하면 척수의 허용선량을 넘지 않으면서 폐 선량을 줄여줄 수 있는 치료계획을 세울 수 있었다. IMRT와 VAMT을 비교해보면 PTV의 선량포함과 척수선량을 고려했을 때 IMRT 치료계획에서 보다 좁은 각도를 이용한 치료계획이 가능하였고, 이는 폐 선량을 좀 더 줄여줄 수 있는 결과를 얻을 수 있었다.
