Although, the history of orthotic treatment for idiopathic scoliosis goes back more than fifty years, the mechanism of curve control by spinal orthosis is still controversial. Hypothetical explanations have been provided but few, if any, have been tested clinically. This study aims at the biomechanical evaluation of a spinal orthosis (Milwaukee brace) in order to improve understanding about the mechanism of curves control in orthotic movement. From the results of the study, the change of the interface pressure between the patient's body and thoracic pad, and the tension of the thoracic strap were highly correlated (r=0.84) as patients performed different lying postures and daily activities. Lying on the thoracic pad is found to have the highest correctional force among different lying postures that may be favourable for preventing curve deterioration. The findings indicate that an increase in tension of the thoracic strap will increase the interface pressure on the thoracic pad and thus increase the resultant force exerted on the patient's body by the thoracic pad. Care must be taken as an excessive strap tension will increase discomfort and restrict body shifting exercises. The results also suggest that in scoliosis with thoracic lordosis, a short outrigger (small pulling angle of the thoracic strap) should be used as it will decrease the anteriorly directed force component so as to prevent exaggerating the thoracic lordosis.

Abstract Orthosis-wearing compliance is considered to be an important factor in the outcome of orthotic treatment for idiopathic scoliosis (Rowe, et al. 1997; Katz, et al. 1997). However, at the present time a reliable and objective method of measuring orthosis-wearing time is lacking. Current estimates are based on self-reported compliance and estimated wear and tear of the orthosis itself. Availability of an accurate and reliable technique to measure how long a patient wears a prescribed spinal orthosis will allow clinicians to objectively study the relationship between patient compliance and outcome of orthotic treatment, and arrive at rational guidelines for prescribing orthosis wearing hours. The purpose of this study was to develop an accurate and reliable method to objectively measure spinal orthosis-wearing time.

Introduction. Idiopathic scoliosis is a structural and lateral curvature of the spine for which a currently recognizable cause has not been found and there is no basic evidence for physical and radiographic pathology. Complications. Scoliosis could be a cause of the back pain, deformities, respiratory and cardiology problems. There is a higher risk for decreasing of bone mineral density. Diagnosis and Management. Physical examination, radiography and stereophotogrametry are used in diagnostics of idiopathic scoliosis. The management of idiopathic scoliosis can be conservative or operative. The main forms of conservative management are: therapy exercises, electrical stimulation and spinal orthosis. The primary aim of scoliosis management is to stop curvature progression. The improvement of pulmonary function (vital capacity) and treatment of pain are also of major importance. The guidelines for Conservative Management of Scoliosis. The International Society on Scoliosis Orthopaedic and Rehabilitation Treatment gave the guidelines for conservative management of scoliosis. Conservative management of scoliosis includes: a) Lyonaise, Side-Shift, Dobosiewicz, Schroth and other kinesitherapy methods, b) scoliosis intensive rehabilitation which appears to be effective with respect to many signs and symptoms of scoliosis and with respect to impeding curvature progression and c) brace treatment, which has been found to be effective in preventing curvature progression and thus in altering the natural history of idiopathic scoliosis. Conclusion. The International Society has given the standards for kinesitherapy, intensive rehabilitation and spinal orthosis in clinical practice and clinical investigations. Surgical procedures can improve curves in the frontal plane, but have important limitations in maintaining fixation and achieving correction in other planes.

Background: Prediction of in-orthosis curvature at pre-orthosis stage is valuable for the treatment planning for adolescent idiopathic scoliosis, while the position of spinal curvature assessment that is effective for this prediction is still unknown. Objectives: To compare the spinal curvatures in different body positions for predicting the spinal curvature rendered by orthosis. Study design: A prospective cohort study. Methods: Twenty-two patients with adolescent idiopathic scoliosis (mean Cobb angle: 28.1°± 7.3°) underwent ultrasound assessment of spinal curvature in five positions (standing, supine, prone, sitting bending, prone bending positions) and that within orthosis. Differences and correlations were analyzed between the spinal curvatures in the five positions and that within orthosis. Results: The mean in-orthosis curvature was 11.2° while the mean curvatures in five studied positions were 18.7° (standing), 10.7° (supine), 10.7° (prone), –3.5° (prone bending), and −6.5° (sitting bending). The correlation coefficients of the in-orthosis curvature and that in five studied positions were r = 0.65 (standing), r = 0.76 (supine), r = 0.87 (prone), r = 0.41 (prone bending), and r = 0.36 (sitting bending). Conclusion: The curvature in recumbent positions (supine and prone) is highly correlated to the initial in-orthosis curvature without significant difference. Thus, the initial effect of spinal orthosis could be predicted by the curvature in the recumbent positions (especially prone position) at the pre-orthosis stage. Clinical relevance Prediction of in-orthosis correction at pre-orthosis stage is valuable for spinal orthosis design. This study suggests assessing the spinal curvature in recumbent position (especially prone position) to predict the initial in-orthosis correction for optimizing the orthosis design.

TheSŭngjŏngwŏn ilgi (Daily Records of the Royal Secretariat)is one of the major chronicles of the events of the Chosŏn Dynasty (1392–1910). Although the records prior to the year 1622 are no longer extant, the remaining records from the years 1623 to 1910 meticulously recount the daily activities of the reigning Chosŏn kings, including copious information on their physical and mental status. Because the king’s health was considered as important as other official affairs in many respects, detailed records were kept of royal ailments and how court doctors treated them. This article surveys the state of Korean-language scholarship on the medical content of theDaily Recordsand presents selected translations to demonstrate how this valuable historical source can shed light on both the social history of Chosŏn medicine and the political importance of kingly health at the Chosŏn court.

In the paper we discussed and analyzed the issues that confront practicing orthopedists with the most mysterious and at the same time the most studied vertebral column lesion in children and adolescents - idiopathic scoliosis. Nowadays a great amount of information on its various aspects has been already accumulated, but a practical output in the form of a system of effective treatment has not been yet found and (we can’t even speak about) there is no speech at all about the prevention (prophylactic) of the disease (scoliosis). On the basis of the own many year’s experience with this category of patients and the results of a comprehensive multi-faceted survey, the authors acquired the right to form their own point of view on the etiology and pathogenesis of the three-plane deformation in orthograde human (homo erectus). In this paper, the authors present their reflections on the history of the study of scoliosis, the terminology, statistical indicators and the existing views on its origins. Concerning argumentation on the own findings (conclusions) and views on the disease the authors plan to tell in the following sections.
