动态视功能差异性的探究
|
摘要
目的通过检测前庭习服前后受试者的动态视力功能,以优化和完善动态视力相关评估标准。方法应用前庭功能检查系统检测16名健康受试者静态及动态视功能。结果当向左、向右摆头速度达到一定速率时,前庭习服前后受试者动态视力存在差异。结论受试者通过前庭习服,前庭系统预刺激后敏感性降低,其动态视力变化情况明显优于习服前,前庭功能适应性锻炼及地面训练对动态视力可能存在影响。
Objective To detect the dynamic visual acuity(DVA) before and after vestibular habituation of subjects in order to optimize the DVA assessment criteria.Methods The vestibular function examination system was applied to the detection of static and dynamic visual function in 16 healthy subjects.Results When the speed of left or right swinging was fast enough,DVA before and after vestibular habituation was different.Conclusion Subjects with vestibular habituation can reduce their sensitivity to the vestibular system,the changes in DVA are better than before habituation,and the vestibular function adaptability training may have effect on DVA.
