Virtual Reality Technology In The Clinical Application Of Hand Dysfunction After Stroke

Stroke is a main cause of global human death and disability. Nearly 7,000,000 such patients live in our country. Besides, there is an increasing number of 2,000,000 new patients every year, of whom 70% to 80% can’t live independently as a result of the disability.85% of the patients have problems with their hand functions at the beginning of the disease.30% to 36% of them still suffer from hand function disability after 6 month of their disease, which affect their sport functions and daily activities. Therefore, it is of great significance to improve such patients; hand functions by searching for positive and efficient ways of recovery treatment. At present, traditional recovery trainings are being adopted, of which the process is boring and makes patients lose their interest easily. At the same time, rehabilitation therapists have such heavy work to do that they soon become tired. As a consequence, such trainings are less efficient.Virtual Reality is a virtual environment of imitating real things (such as walking, running, fetching things, drawing, etc) by computer. It put patients into this environment by using various sensor devices to realize interactive technology directly between patients and the virtual environment. In such a virtual environment, patients will have a feeling of real involvement and receive signals from the environment through the sensor device. Meanwhile, computer can record the patient’s function information accurately and achieve interaction between patients and computer through the virtual environment. My research aims to test the function of VR and its marketing value of curing dysfunction hand in hemiparetic patients after stoke by means of fugul-meigel assessment chart, Brunnstrom grading assessment, improved bathel data statistics analysis.
