Background: Breathing is the essential step of Pilates exercise and can be used to activate core muscles. Although the effects of breathing exercise on pain, breathing muscles, and cervical posture have been extensively studied, little is known about the impact of Pilates breathing on spinal posture and alignment. Purpose: To determine the effect of 3D-Pilates breathing exercise on spinal curvature and alignment of healthy adults during corrected to normal alignment. Design: One group pre-post test design Methods: Eighteen participants were given a 3D-pilates breathing exercise twice a week (20 minutes per session) for three weeks and warmed up for 10 minutes before each exercise session. To examine spinal curvature and alignment of each subject, this study used radiation free rasterstereography (Formetric III, Germany). Paired t-test and Wilcoxon signed rank test were performed to determine the difference between pre and post exercise. Results: There were statistically significant differences in height (p<.001), kyphosis angle (p<.05), trunk imbalance (p<.05), kyphotic apex (p<.01), cervical fleche (p<.05), pelvic tilt (p<.01), and lateral deviation (p<.05) between before and after 3D Pilates breathing exercise. However, there was no significant difference in lordosis angle. Conclusions: The study results indicated that three week 3D-pilates breathing exercise program could be presented as an effective rehabilitation method for improving spinal curvature and alignment.

Objective: Flexed posture commonly increases with age in older adults and is characterized by kyphosis and forward head posture. Changes in the posture with age affect both balance and mobility. This study was conducted to examine the effects of a cervical stabilization exercise for community-dwelling older adults to improve balance. Design: Two groups pretest-posttest design. Methods: Fifty older adults were randomly assigned into the cervical stabilization exercise group (n=24) and control group (n=25). The cervical stabilization exercise group (n=24) participated in group exercise for 60 minutes twice a week over 4 weeks. Timed up and go test (TUG), four square step test (FSST), functional reach test (FRT), postural sway, cervical range of motion (CROM), proprioception, craniovertebral angle (CVA) were evaluated before and after the intervention. Results: TUG, FSST, FRT, CROM, Proprioception, CVA showed significantly greater improvement, compared with a control group (p<0.05). Conclusions: Findings of this study demonstrate that cervical stabilization exercise can help improve not only neck functional capacities but also balance. Therefore, it may be used as an effective balance exercise program for community-dwelling older adults.

Purpose: The purpose of this study was to investigate the effect of thoracic-lumbar dissociation motion and slump motion on thoracic-lumbar erector spinae and rectus abdominis muscle activity. Methods: Seventeen healthy adult volunteers participated in this study. All participants performed two motions (thoracic-lumbar dissociation motion, slump motion). Muscle activation during the two motions was measured using a surface electromyography device. The data from this were collected from the iliocostalis thoracis, iliocostalis lumborum, and rectus abdominis. The activities of these muscles before and after each motion were then compared. Results: The iliocostalis thoracis activation was significantly greater during the thoracic-lumbar dissociation motion than during the slump motion (p <0.05). The iliocostalis lumborum activation was greater during the slump motion than during the thoracic-lumbar dissociation motion (p <0.05). The rectus abdominis activation was lesser during the slump motion than during the thoracic-lumbar dissociation motion (p <0.05). Conclusion: This study confirmed that individual contraction of the erector spinae muscles is possible during thoracic-lumbar dissociation motion, which increases the stability of the thoracic spine. In addition, this motion could improve control of the rectus abdominis. Therefore, thoracic-lumbar dissociation motion should be considered for rehabilitation programs for patients with kyphosis and back pain.

Many mouse models of rheumatoid arthritis have been identified, but only a limited number are present for axial spondyloarthritis (AxSpA). Collagen Ab-induced arthritis (CAIA) is one of the most widely used mouse models of arthritis, and it is complement-dependent. We found that mice developing CAIA also developed spinal lesions similar to those found in AxSpA. To induce CAIA, mice were injected intraperitoneally at day 0 with anti-collagen Abs, followed by LPS injection at day 3. CAIA mice demonstrated a significant kyphosis through the spine, as well as hypertrophic cartilage and osseous damage of the intravertebral joints. Immunohistochemical staining of the kyphotic area revealed increased complement C3 deposition and macrophage infiltration, with localization to the intravertebral joint margins. Near Infrared (NIR) in vivo imaging showed that anti-collagen Abs conjugated with IRDye^® 800CW not only localized to cartilage surface in the joints but also to the spine in arthritic mice. We report here a novel preclinical mouse model in which, associated with the induction of CAIA, mice also exhibited salient features of AxSpA; this new experimental model of AxSpA may allow investigators to shed light on the local causal mechanisms of AxSpA bone and soft tissue changes as well as treatment.

The purpose of this study was to discover practical health problems which hemodialysis clients experienced so as to present basic data for development of a health assessment tool. The research subjects were 70 clients receiving hemodialysis in Seoul and Inchon from Mar. 1996 to Sep. 1996. Data were collected by researcher's informal indepth interview and nurses' open ended question. Content analysis was applied to collect similar contents and common experiences in order to derivate concepts and categories for better understanding of hemodialysis clients' experiences. As a result, 9 categories derivated to identify the health problems of clients receiving hemodialysis were as follows : 1) They experienced 'the decreased digestive function' which contained the changed appetite, nausea, vomiting, constipation and diarrhea. 2) They experienced 'the decreased respiratory and circulatory function' which contained dyspnea, changed blood pressure, tingling sensation and the fear of aggrevated vascular condition. 3) They experienced 'the aggrevated oral condition' which contained dry mouth and destruction of teeth and their soft tissue. 4) They experienced 'the decreased sensory function' which contained visual disturbances, sensation difficulty, and hearing loss. 5) They experienced 'the aggrevated skin condition' which contained dark brown skin color, dry skin (and hyperpigmentatic freckle, seborrheric keratosis, scale), itching sense, and alopethia. 6) They experienced 'the decreased urinary reproductive function' which contained anuria or oliguria, dysmenorrhea, sterility and decreased libido. 7) They experienced 'the restricted activity' which contained decreased activity, muscle cramp and stiffness of joint. 8) They experienced 'the changed mental status' which contained memory disturbance, decreased cognition, disorientation, neurosis and psychosis. 9) They experienced 'the aggrevated general condition' which contained kyphosis, weight loss, fatigue, sleep disturbance, bleeding tendency, inflammation, generalized edema and foul oder of uremia.

As many humans age, degenerative lumbar spinal stenosis (DLSS) becomes a major cause of lower limb discomfort and disability. By surgical treatment method of DLSS, the existing surgical treatment methods using internal fixation have showed degeneration changes of an adjacent vertebrae and loss of lumbar spine lordosis-kyphosis due to eliminating a motion. For solving the problems of internal fixation, a novel interspinous spacer has been developed to treat DLSS by surgical treatment method. In this study, we evaluated the biomechanical effects of the interspinous spacer on the kinematics of the porcine lumbar spine before and after insertion of the implant. For this purpose, a device that is capable of measuring 3-D motions were built based on direct linear transformation (DLT) algorithm written with MATLAB program. Results showed that in extension, a change of the mean angle between the intact and the implanted specimens at L4-L5 was 1.87 degree difference and the implant reduced the extension range of motion of the L4-L5 (p＆lt;0.05). But the range of motion in flexion, axial rotation and lateral bending at the adjacent segments was not statistically affected by the implant. In conclusion, we thought that interspinous spacer may have remedical value for DLSS by flexing human lumbar spine.

Objective : The safety of titanium metal cages in tuberculous spondylitis has not been investigated. We evaluated the outcome and complications of titanium mesh cages for reconstruction after thoracolumbar vertebrectomy in the tuberculous spondylitis. Methods : There were 17 patients with 18 operations on the tuberculous spondylitis in this study. Sixteen patients were operated with anterior corpectomy and reconstruction with titanium mesh cage followed by posterior transpedicular screw fixations on same day, two pateints were operated by either anterior or posterior approach only. After the affected vertebral body resection and pus drainage from the psoas muscle, titanium mesh cage, filled with morselized autogenous bone, was inserted. All the patients had antituberculosis medication for 18 months. The degree of kyphosis correction and the subsidence of cage were measured in the 15 patients available at a minimum of 2 years. Outcome was assessed with various cross-sectional outcome measures. Recurrent infection was identified by serial ESR[Erythrocyte Sedimentation Rate] and CRP[Cross Reactive Protein]. Results : There was no complication from the use of a titanium mesh cage. Recurrent infection was not detected in any case. Average preoperative of $9.2^{\circ}$ was reduced to $-2^{\circ}$ at immediate postoperative period, and on final follow up period kyphotic angle was measured to be $4.5^{\circ}$. Postoperatively, subsidence was detected in most patients especially at ambulation period, however further subsidence was prevented by the titanium mesh cage. Osseous union was identified in all cases at the final follow-up. Conclusion : The cylindrical mesh cage is a successful instrument in restoring and maintaining sagittal plane alignment without infection recurrence after vertebrectomy for tuberculous spondylitis.

Objective : The purpose of this study is to evaluate the clinical outcome of the two-stage operation for thoracic tuberculous spondylitis. Methods : Eleven patients [4 male, 7 female] with thoracic tuberculous spondylitis were treated with two-stage operation. First stage consisted of anterior debridement and interbody fusion using rib graft and second with posterior instrumentation with fusion. Mean age was 46 years, and mean follow-up period was 18 months. All patients were treated with 12 months of antituberculotic medication postoperatively, and evaluated before and after surgery with respect to pain level, neurological status, associated lesions, hematological parameters and change of kyphotic angle. Results : The associated lesions were pulmonary tuberculosis in 4 cases. There were no recurrences of infection and bone union was obtained within 6 months of the operation in all cases. Changes in the pain severity, neurological status, and hematological parameters demonstrated significant clinical improvement in all patients. The mean kyphotic angle was corrected from $17.8^{\circ}$ to $9.8^{\circ}$ after surgery. The most recent follow-up of the mean kyphotic angle was $12.3^{\circ}$, with a loss of correction of $2.5^{\circ}$. The preoperative VAS averaged to be 7.18 [range, 4-10]. It decreased significantly an average of 1.45 [p <0001]. Conclusion : These results indicate that two-stage surgical treatment for thoracic tuberculous spondylitis provid safe and satisfactory results. Spine instability and kyphosis can be also prevented by two-stage operation.

Objective : The purpose of this study was to determine the efficacy of bone cement-augmented short segment fixation using percutaneous screws for thoracolumbar burst fractures in a background of severe osteoporosis. Methods : Sixteen patients with a single-level thoracolumbar burst fracture (T11-L2) accompanying severe osteoporosis treated from January 2008 to November 2009 were prospectively analyzed. Surgical procedures included postural reduction for 3 days and bone cement augmented percutaneous screw fixation at the fracture level and at adjacent levels without bone fusion. Due to the possibility of implant failure, patients underwent implant removal 12 months after screw fixation. Imaging and clinical findings, including involved vertebral levels, local kyphosis, canal encroachment, and complications were analyzed. Results : Prior to surgery, mean pain score (visual analogue scale) was 8.2 and this decreased to a mean of 2.2 at 12 months after screw fixation. None of the patients complained of pain worsening during the 6 months following implant removal. The percentage of canal compromise at the fractured level improved from a mean of 41.0% to 18.4% at 12 months after surgery. Mean kyphotic angle was improved significantly from $19.8^{\circ}$ before surgery to 7.8 at 12 months after screw fixation. Canal compromise and kyphotic angle improvements were maintained at 6 months after implant removal. No significant neurological deterioration or complications occurred after screw removal in any patient. Conclusion : Bone cement augmented short segment fixation using a percutaneous system can be an alternative to the traditional open technique for the management of selected thoracolumbar burst fractures accompanied by severe osteoporosis.

Objective : At present, gold-standard technique of cervical cord decompression is surgical decompression and fusion. But, many complications related cervical fusion have been reported. We adopted an extended anterior cervical foraminotomy (EACF) technique to decompress the anterolateral portion of cervical cord and report clinical results and effectiveness of this procedure. Methods : Fifty-three patients were operated consecutively using EACF from 2008 to 2013. All of them were operated by a single surgeon via the unilateral approach. Twenty-two patients who exhibited radicular and/or myelopathic symptoms were enrolled in this study. All of them showed cervical cord compression in their preoperative magnetic resonance scan images. Results : In surgical outcomes, 14 patients (64%) were classified as excellent and six (27%), as good. The mean difference of cervical cord anterior-posterior diameter after surgery was 0.92 mm (p<0.01) and transverse area was $9.77mm^2$ (p<0.01). The dynamic radiological study showed that the average post-operative translation (retrolisthesis) was 0.36 mm and the disc height loss at the operated level was 0.81 mm. The change in the Cobb angle decreased to 3.46, and showed slight kyphosis. The average vertebral body resection rate was 11.47%. No procedure-related complications occurred. Only one patient who had two-level decompression needed anterior fusion at one level as a secondary surgery due to postoperative instability. Conclusions : Cervical cord decompression was successfully performed using EACF technique. This procedure will be an alternative surgical option for treating cord compressing lesions. Long-term follow-up and a further study in larger series will be needed.
