应用肌电图定量分析前庭功能障碍的实验研究

目的 通过肌电图与姿势反射的相关性研究,探讨肌电图检测前庭功能障碍的意义。方法 将受试大鼠分成四组,Ａ组：正常大鼠９只;Ｂ组;前庭功能障碍１周内大鼠１２只;Ｃ组：前庭功能障碍３个月大鼠３只;Ｄ组：前庭损伤５个月后功能恢复大鼠６只。记录单侧前庭功能障碍时大鼠颈顶部头夹肌静息状态的肌电活动和眼震电图。结果 正常大鼠两侧头夹肌肌电图振幅相等,为２５μＶ;单侧前庭功能障碍急性期同侧肌电振幅降低,为２－３μ     

The Application of Virtual Reality Technology to Ear Microsurgery

The broad application of virtual reality (VR) to medicine has been of great value. The virtual surgery is one of technically difficult applications. With the expansion of the increasingly fine and complicated ear microsurgery, new methods are required to train the doctors. It is necessary and of practical significance to apply VR to the ear micro-operation, which is a functional operation with high precision and great difficulties. In this article,medical VR applications were reviewed. The application of VR to the ear microsurgery was discussed and the virtual ear microsurgery system was designed.
