I have processed all the data by using SPSS PC+. And my research process was investigated for 34 students on the Forward Bending Test, Foot Printer Test, Feedoscope Test, X-ray Test and so on. The object of this thesis is to study the correlation between spine deformity and foot abnormality in a theoretical and empirical method. The main results of this study were as follows: 1. There was statistical significance on the correlation between foot length and spine length. 2. Spinal curve is the smallest on the pes plannus group and the biggest on the pes cavus group without statistical significance. 3. Left lumbar curve is the smallest, and right thoracic spine curve is the biggest on the left foot pattern group with statistical significance. 4. On the foot weight bearing groups, there was statistical significance both of between left and right foot groups. 5. There was no statistical significance on the t-test analysis between left and right foot area according to spinal curve typology. But there was tendency that thoracic spine curve is bigger in the same side of the foot area and lumbar spine curve is bigger in the opposite side of foot area.

The degenerative lumbar spinal stenosis (DLSS) is a disease inducing low back pain, leg pain, convulsion. numbness, and neurogenic claudication from compression of nerve root. Intervertebra fixation was reported to increase the degeneration of neighbor lesion after treatment. Recently, a new surgical technique of inserting a fixator between interspinous processes has been introduced. The purpose of this study is to design the interspinous process fixator with flexibility to complement the trouble of using fixator in DLSS. This study evaluated the existing fixator through the mechanical test and modified it using the finite element analysis (FEA). The evaluation was based on the displacement, stiffness and von-Mises stress obtained from the mechanical test and calculated from the FEA in the biomechanical loading condition. Effects of variation in length and thickness were investigated to design an optimal fixator. Three prototypes were manufactured using FEA results. Mechanical tests under the biomechanical loading condition were performed to select the best one from these three. The selected fixator increased flexiblity by 32.9%.

An ayu (Plecoglossus altivelis) farm in Korea recently experienced an epidemic of vertebral column deformities where about 90% of fry displayed a vertebral column that was grossly opaque along either the cranial part of the column or its entire length. Abnormal fish were lordotic, scoliotic and/or kyphotic about midway down the spine. Examination of serial sections of whole fish showed only histological lesions in the vertebral column and suggested some disturbance in the early development of the vertebral centrum. Such abnormalities included a frayed spinal or notochord sheaths with irregular thickening and compression, mal-absorbed notochord cells, thickening of around cell layer and hypercellularity on both facets of the notochord sheath. No parasites, fungi, or bacteria were detected. While this lesion has only been reported once in the past, this is the first report of histopathological findings.

The purpose of this study was to analyze the variation of muscle function and gait ability according to regular spinal stabilization exercise program for private security guards and the conclusion as follows. First, it increased lumbar extension strength and lumbar flexion strength both exercise and non exercise group according to the variation of muscle function with the spinal stabilization exercise program. There was significant difference between exercise and non exercise group after the program but not before the program. Second, it appeared the functional vanishment of lumbar extensor before the program both exercise and non exercise group according to the variation of muscle function with the spinal stabilization exercise program for lumbar flexor extensor ratio. Third, it analyzed for the spinal stabilization with 8 ways according to the variation of muscle function with the spinal stabilization exercise program for the change of the spinal stabilization. The spinal stabilizaton increased each angle for the execise group but decreased or not changed for non exercise group. Fourth, it used 10m gait test for the speed and step length according to the variation of muscle function with the spinal stabilization exercise program. It appeared the increasement of gait ability for exercise group and there was significant difference between exercise and non exercise group. In conclusion, there was a positive effect for lumbar extension strength, lumbar flexion strength, lumbar flexor extensor ratio, spinal stabilization, and gait ability with regular spinal stabilization exercise program. This means that spinal stabilization exercise program give positive effect to the decrease of back pain and the development of muscular strength for private security guard, also will help to recover and return to work more faster. Also, it seems that the exercise prescription program may be applicable to prevent or to improve the function for private security guard.

A 6-year-old, intact male maltese was presented with hindlimb ataxia of 4 day duration. Physical and neurological examinations revealed a bright, alert, and responsive dog, with no evidence of cranial nerve deficits, conscious proprioceptive deficits. Spinal reflexes of the hind and forelimbs were normal. Patellar, cranial tibial, and withdrawal reflexes were normal. Pain could not be elicited on manipulation of the neck or palpation of the spinal column. Survey radiographs of the vertebral column were unremarkable. Computed tomography (CT) scans in the transverse plane were performed. The results of CT imaging were unremarkable. Magnetic resonance imaging (MRI) in both sagittal and transverse planes was performed. The extent of the lesion was 25 mm in length by 4 mm in thickness. The spinal cord was deviated ventrally and appreared thinner. On T1-weighted and FLAIR images, a discrete hypointense lesion dorsal to the spinal cord was observed at L1-2 which was contiguous with the subarachnoid space. On T2-weighted images, this region was hyperintense, consistent with a fluid-filled structure. The signal intensity of the cysts was equivalent to cerebrospinal fluid (CSF). Surgical treatment involving dorsal laminectomy had successful outcomes.

Background: This study was designed to evaluate the clinical effectiveness of traditional Korean medicine treatment for lumbar spinal stenosis as assessed by radiological criteria. Methods: This was an observational study of 122 patients who were diagnosed with lumbar spinal stenosis and admitted to Jaseng Hospital between January 2016 and June 2017. They were analyzed according to sex, age, cause of disease, disease stage, length of admission, type of stenosis, morphological grade, and dural sac cross-sectional area. All patients were treated with traditional Korean medicine. Patients were assessed with the Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) and EQ-5D before and after treatment. Results: Regarding the distribution of the factors analyzed, these were of note: more females than males (1:3.52); and highest proportions were age more than 70 years (37.70%), cause of lumbar spinal stenosis unknown (67.21%), and subacute stage (42.62%). Comparing before and after treatment, the NRS score for low back and pelvic pain decreased from $6.14{\pm}1.71$ to $4.28{\pm}1.91$ (p < 0.001), and the NRS score for radiating pain and numbness decreased from $6.27{\pm}1.61$ to $2.02{\pm}1.54$ (p < 0.001). ODI decreased from $46.86{\pm}19.40$ to $33.63{\pm}18.66$ (p < 0.001), and gait-related ODI decreased from $3.34{\pm}1.23$ to $2.80{\pm}1.11$ (p < 0.001). There were no statistically significant differences in improvement of the NRS, ODI, gait-related ODI, and EQ-5D for morphological grade and dural sac cross-sectional area. Conclusion: Traditional Korean medicine is effective treatment for patients with lumbar spinal stenosis. Even in patients with severe radiological findings, it is possible to reduce pain and improve quality of life.

The purpose of this research was to investigate the effects of respiratory rehabilitation using a wind instrument for patients suffering from spinal cord injuries. From January 15, 2018 to April 15, 2018, we conducted ten 1-hour sessions of a harmonica program with eight patients with spinal cord injuries with average age of 37 years who could not perform abdominal breathing by themselves. We measured and compared patients' breathing capacity before and after the 10 sessions. Designed particularly for patients with spinal cord injuries resulting in a limited range of neck movement, the study used a 10-hole diatonic harmonica whose length was relatively short. For those patients who had difficulty using their hands, a harmonica holder was provided. Participants were trained to play simple tunes. They were guided to use abdominal breathing to make sounds, with emphasis on those parts requiring long and strong breathing. The results showed that for all eight patients both their breathing volume and their inspiratory volume increased following participation in the harmonica program. Also, the program had psychological benefits (e.g., more life satisfaction and less sadness) and additional physical benefits (e.g., less dizziness due to low blood pressure and better phlegm spitting). This study offers a unique way to help patients with spinal cord injuries to improve their breathing capacity, which may also be associated with a greater quality of life.

Background: The purpose of this study was to compare and analyze the differences in charges and length of stay per case between spine specialty hospitals and non-specialty hospitals, and to identify the factors that influenced them. Methods: This study used claims data from the Health Insurance Review and Assessment Service, including inpatient visits from January 2021 to December 2022. The healthcare facility status data was used to identify the characteristics of study hospitals. Multilevel analysis was conducted to identify factors associated with the charges and Poisson regression analysis was conducted to analyze the length of stay between spine specialty hospitals and non-specialty hospitals. There were 32,015 cases of spine specialty hospitals and 17,555 cases of non-specialty hospitals. Results: For four of five common spinal surgeries, specialty hospitals shaped longer length of stay than those of non-specialty hospitals. Multilevel and Poisson regression analysis revealed that regardless of the type of surgery, higher age and higher Charlson comorbidity index scores were significantly associated with an increase in both the charges per case and length of stay (p<0.05). However, when hospitals were located in metropolitan areas, there was a significant decrease (p<0.05). Conclusion: This study found that specialty hospital had higher inpatient charges and loner length of stay contrary to the previous study results. Further studies will be needed to find which contribute to the differences.

We reviewed 9 cases of pyogenic spondylodiscitis following percutaneous endoscopic lumbar discectomy (PELD). Microbiologic cultures revealed 6 causative organisms. Five patients were managed conservatively and four were treated surgically. The mean follow-up period was 20.6 months and the average length of hospitalization was 24 days. Radiological evidence of spinal fusion was noted and infection was resolved in all patients. Although PELD is a safe and effective procedure, the possibility of pyogenic spondylodiscitis should always be considered.
