The Effects of Increasing Thoracic Mobility on Lumbar Stability

OBJECTIVE: To determine the effects on the lumbar stability caused by various thoracic exercise programs, the extent of spinal posture correction and the increase in thoracic mobility to the extension direction. METHOD: Exercise programs, which can increase the thoracic mobility to the extension direction, were applied to the exercise group. The control subjects were trained for the correct posture according to ergonomic principles by exercise at home and at the clinic. Both groups had three sessions of exercise program per week for 8 weeks. RESULTS: A comparison of the various parameters in the exercise group before and after exercise showed that the VAS, thoracic kyphosis and lumbar mobility decreased significantly (p <0.05), and the thoracic mobility in the extension direction, chest expansion, maximal elevation of the arms and spinal length increased significantly (p <0.05). In addition, the thoracic kyphosis and lumbar mobility increased significantly (p <0.05), and thoracic mobility in the extension direction, chest expansion, maximum elevation of the arms and the spinal length decreased significantly (p <0.05), but the VAS did not show a significant difference. CONCLUSION: A thoracic exercise program, which can correct the posture, improve the functional restrictions of the thoracic spine and reduce the lumbar mobility, is very important.

Evaluating Rehabilitative Medical Information on the Korean Internet: Carpal Tunnel Syndrome, Stroke

OBJECTIVE: To analyse the sites of medical information by popular search engines and its appropriateness as guidance to medical information. METHOD: The search phrase "carpal tunnel syndrome" (CTS) and "stroke" were entered into four commonly used Korean web search engines. 24 and 21 web-sites from search engines were gathered, respectively. These web sites then were evaluated for authorship, content, and an informational value score was assigned to each. RESULTS: According to authorship in CTS, 16.6 percent of the sites were commercial sites and 20.8 percent were authored by oriental medical doctors with 37.5 and 16.6 percent by general physicians and physiatrists, respectively. With stroke, 9.5 percent was commercial and each 71.4, 19.0, 0 percent was authored by oriental medical doctors, physician, physiatrist respectively. Each 75, 28.6 percent of the sites offered conventional information. The mean informational value of web sites was 51.1, 41.1 points. CONCLUSION: The information about CTS on the internet is of limited quality, inconsistent contentional value, despite of relatively high informational value. With stroke, information was offered by mainly oriental medical doctors, and was not so valuable. The public and medical communities need to recognize these limitations so that the quality of medical information on the internet can be improved.
