The purpose of this study is to investigate the effect of pelvic, Lumbar spine and Cervical spine manipulation on the joint position sense in normal adults. Thirty normal adults were divided into an experimental group of 15 subjects and a control group of 15 subjects. The experimental group was treated with pelvic, Lumbar spine and Cervical spine manipulation with massage, whereas the control group received only massage. Both groups were evaluated in terms of joint position errors (JPEs) using a digital dual clinometer before and after the experiment. The comparison of the JPEs of the experimental group and the control group before and after the experiment showed that the experimental group's cervical spine results were significantly different in the flexion, left lateral flexion, and right rotation (p < .05) and lumbar spine results were significantly different in the flexion and extension (p < .05), but the control group's results were not statistically significant in all items (p > .05). The pelvic, lumbar spine and cervical spine manipulation makes an effect on the joint position sense in normal adults. The findings of this study suggest that the pelvis, lumbar spine and cervical spine manipulation improve the motor ability in people with low joint position sense.

Objectives This study was designed to compare curvature and intervertebral disc angle of the cervical spine in different prone positions. Methods 30 adults aged 19~60 years were enrolled in this study. Volunteers in this uncontrolled trial were taken an x-ray of cervical spine on lateral. Four radiographs were taken for each volunteer, in standing, prone position with U-type pillow (prone position A), rectangular pillow (prone position B), and prone position without pillow (prone position C). After measuring the cervical angle, Ishihara index, craniovertebral angle, intervertebral angle, we analysed the lordotic angle and foward head posture. The data was anlysed by analysis of variance and pearson correlation coefficient. Results Cervical angles of prone position without pillow (prone position C) significantly decreased compared with those in standing position (p<0.001). Ishihara index of prone position without pillow (prone position C) also significantly decreased compared with those in standing position (p<0.001). Craniovertebral angle of prone position with pillow (prone position A, B) significantly increased with those in standing position (p<0.001). Intervertebral angle of prone position with pillow (prone position A, B) at the C3-7 levels significantly increased with those in standing position (p<0.001). Intervertebral angle of prone position without pillow (prone position C) at the C3-5 levels significantly decreased with those in standing position (p<0.001). The angle of intervertebral disc significntly decreased in kyphotic cervical levels. Conclusions Different prone position clearly resulted changes in cervical spine curvature and intervertebral disc angle. And it is related to cervical spine lordotic angle and sagittal alignment in standing position and prone position.

In this study, we present the difference in thoracic reposition sense in young people (24.00 ±2.20 years old) with and without habitual slouched posture in two target positions of half flexion and half extension. People with habitual slouched posture (n = 20; 11 men and 9 women) and people without slouched posture (n = 20; 10 men and 10 women) were recruited from three universities. Thoracic spine (T-spine) repositioning errors were measured in two target positions (half flexion and half extension). People with habitual slouched posture showed significantly higher thoracic repositioning error in the extension target position than did people without slouched posture (P<0.05). There was no difference in repositioning error in the flexion target position between the two groups (P>0.05). In conclusion, people with habitual slouched posture show lower T-spine repositioning sense in extension than do people without slouched posture. A rehabilitation program to treat habitual slouched posture, such as postural correction education, should be implemented for individuals with decreased position sense of the T-spine.

Objectives : We investigated the possibility of cervical spine misalignment caused by scalenus anticus syndrome to find out how it affects cervical spine misalignments. Methods : 28 patients with scalenus anticus syndrome (sample group), along with 21 participants without neck pain (control group), who attended the Dept. of Oriental Rehabilitation Medicine, College of Oriental Medicine, Dong-guk University from the 20th of June to the 30th of November, 2006 were investigated. After researching misalignments through neutrality, flexion and extension lateral x-ray examination views, we measured the difference of each length of cervical spine misalignment. We analyzed the relationships among the neutrality lateral, flexion lateral and extension lateral positions. Results : We found with statistical significance that there were differences in length of cervical spine misalignments between the sample and control groups. Furthermore, we found that C3 and C4 vertebra bodies were shown in lateral neutrality position, only C3 vertebra body in flexion lateral position, and C2, C3, and C4 vertebra bodies in extension lateral position. Conclusions : It is considered that scalenus anticus syndrome could increase cervical spine misalignment which could be a factor in causing cervical spine disease.

Whole spine scanography(WSS)는 전신에 X선을 조사하는 검사로 치료기간 동안 빈번한 X선 조사가 이루어지는 검사이다. 일반촬영 분야에서는 많은 X선이 전신에 조사되는 검사이다. 따라서 논문에서는 Auto image pasta기법의 디지털 WSS 검사에서 환자의 검사방향에 따른 유효선량과 장기선량을 전산모사를 통하여 평가하였고, 영상에서 척추의 확대도와 각도의 변화를 평가하였다. 전후면 자세에서의 평균 유효선량은 0.069 mSv였고, 후전면 자세에서 평균 유효선량은 0.0361 mSv로 약 2배의 차이를 보였다. 전후면 자세에서 남성의 평균 유효선량은 0.089 mSv, 여성에 대한 평균 유효선량은 0.431 mSv로 나타났고, 후전면 자세에서 남성의 평균 유효선량은 0.050 mSv, 여성에서는 0.026 mSv로 나타났다. 확대율에서는 후전면 자세에서 전후면 자세에 비해 5%정도 확대 되었으나 각도에는 큰 변화를 보이지 않았다. 따라서 임상 환경에서 동일한 검사조건에서 환자의 자세를 변화시키는 것만으로도 환자의 피폭선량을 감소시킬 수 있음을 확인하였다. 특히 WSS와 같이 치료기간 동안 반복되는 검사에서 환자의 피폭선량 최적화를 위하여 검사 프로토콜의 재정립이 필요함을 확인하였다.

Objective : Thoracic pedicles have special and specific properties. In particular, upper thoracic pedicles are positioned in craniocaudal plane. Therefore, manipulation of thoracic pedicle screws on the left side is difficult for right-handed surgeons. We recommend a new position to insert thoracic pedicle screw that will be much comfortable for spine surgeons. Methods : We retrospectively reviewed 33 patients who underwent upper thoracic pedicle screw instrumentation. In 15 patients, a total of 110 thoracic pedicle screws were inserted to the upper thoracic spine (T1-6) with classical position (anesthesiologist and monitor were placed near to patient's head. Surgeons were standing classically near to patient's body while patients were lying in prone position). In 18 patients, a total of 88 thoracic pedicle screws were inserted to the upper thoracic spine with the new standing position-surgeons stand by the head of the patient and the anesthesia monitor laterally and under patient's belt level. All the operations performed by the same senior spine surgeons with the help of C-arm. Postoperative computed tomography scans were obtained to assess the screw placement. The screw malposition and pedicle wall violations were divided and evaluated separately. Cortical penetration were measured and graded at either : 1-2 mm penetration, 2-4 mm penetration and >4 mm penetration. Results : Total 198 screws were inserted with two different standing positions. Of 198 screws 110 were in the classical positioning group and 88 were in the new positioning group. Incorrect screw placement was found in 33 screws (16.6%). The difference between total screw malposition by both standing positions were found to be statistically significant (p=0.011). The difference between total pedicle wall violations by both standing positions were found to be statistically significant (p=0.003). Conclusion : Right-handedness is a problem during the upper thoracic pedicle screw placement on the left side. Changing the surgeon's position standing near to patient's head could provide a much comfortable position to orient the craniocaudal plane of the thoracic pedicles.

The driving position of head restraints and the relative risk of neck injury were studied in the computer simulation. MADYMO human model with the detail neck model was used to define the magnitude and direction of internal forces acting on the cervical spine during rear-end impact and to determine the effect of the initial position of the occupant's head with respect to the head restraints. Maximum reaction forces were generated during the head contact to the restraint and relatively large forces were generated at each spinal components in lower cervical spine in proportion to backset and height distance increasement.

The objective of this study is to provide basic information on coupled motions in thoracic spine during lateral bending from a neutral position for football and baseball players as well as for general university students. In the experiment, a total of 30 subjects participated(football players: 10, baseball players: 10, general students: 10). All subjects were in their 20's. The subjects sat on a chair with lumbar support in a neutral position and bent to the right. As a result, for baseball players, coupled motions were observed in the opposite direction of the lateral bending in all parts of thoracic spine. For both football players and general students, coupled motions were observed in the same direction. These results confirmed that unilateral movements like baseball could affect coupled motions.

Objective : To present the accuracy and safety of cervical pedicle screw insertion using the technique with direct exposure of the pedicle by laminoforaminotomy. Methods : We retrospectively reviewed 12 consecutive patients. A total of 104 subaxial cervical pedicle screws in 12 patients had been inserted. We also assessed the clinical and radiological outcomes and analyzed the direction and grade of pedicle perforation (grade 0: no perforation, 1: <25%, 2: 20% to 50%, 3: >50% of screw diameter) on the postoperative vascular-enhanced computed tomography scans. Grade 2 and 3 were considered as incorrect position. Results : The correct position was found in 95 screws (91.3%); grade 0-75 screws, grade 1-20 screws and the incorrect position in 9 screws (8.7%); grade 2-6 screws, grade 3-3 screws. There was no neurovascular complication related with cervical pedicle screw insertion. Conclusion : This technique (technique with direct exposure of the pedicle by laminoforaminotomy) could be considered relatively safe and easy method to insert cervical pedicle screw.

Purpose: The aim of this study was to investigate the effect of mandible position on proprioception and range of motion (ROM) during neck stabilization exercise using a sling in healthy adults. Methods: The subjects were randomly assigned to either a sling exercise and mandible open group (n=10) or a sling exercise and mandible closed group (n=12). The sling exercise-mandible open group and sling exercise-mandible closed group took part in an exercise program for 30min, three times per week for 4 weeks. After each training session, head repositioning accuracy (HRA) and the ROM of the cervical spine were measured. Wilcoxon's test was conducted to verify changes within each group, and the Mann-Whitney U test was performed to examine between-group differences. Results: The HRA of the cervical spine was significantly increased during left rotation and extension in the sling exercise-mandible open group. In addition, there were significant differences in both rotations and extension in the two groups. The ROM of the cervical spine increased significantly during both rotations in the sling exercise-mandible closed group. In addition, there was a significant difference in right rotation and extension in both groups. Conclusion: Cervical stabilization exercise using a sling, with the mandible closed increased proprioception and the ROM of the cervical spine.
