Multıpl sklerosis hastaları için sanal-artırılmış gerçeklik tabanlı test ve rehabilitasyon yazılımları tasarımı

Physical disability is a fact in some neurologic disorders, such as Multiple Sclerosis. One of the treatments of disability is routine physical exercises, or "rehabilitation". However, rehabilitation at hospitals is often unattractive for the patients. Another difficulty is the objective assessment of the outcome of rehabilitation on disabilities, as assessment often depends on the subjective opinion of the physician. In our present study, we offer exergaming rehabilitation at home (telerehabilitation) and an objective method for measuring the physical performance of people with multiple sclerosis using a Virtual Reality tool, to assist the decision of improvement or no change in the patient's health status. Telerehabilitation is provided by custom made exergames specifically designed for patients with upper extremity disabilities. Our novel performance measurement method keeps the time taken by a patient to finish a physical test and measures the angles of interest between predetermined upper extremities. The measurements are recorded and saved for future patient progress comparisons. Thus, improvement-no change decisions can be less dependent on subjective opinions. Preliminary performance experimentation has been carried out before and after playing our Virtual Reality exergames. Results reveal that our method is capable of measuring angles with an error margin of 6.44%. The accuracy of our method is 86.00%. The sensitivity, i.e. detecting improvements in patient performances, of our method is higher at 88.24%. The specificity, i.e. detection of no change in performances, is lower at 82.25%.
