Abstract： 本工作首次将一种运动分析系统,即视觉自动电视摄相信息处理系统(optical automatic TV-image processor,E.L. I.T.E system)用于动物运动方式的定量分析,比较了猫一侧前庭神经切断前后在跨越转动横梁测试中运动方式的变化.结果如下:在横梁静止条件下,猫术后行走的初始身高明显下降,步距变短,步频降低,呈缓慢的蹒跚步态,继而各参量逐渐增加,分别在术后45和70d恢复到术前水平.在横梁转动条件下,猫初始均降低身高,但步距、步频和运动速度的相对变化因转动速度和恢复时程的不同而异,显示了动物在代偿初期运动行为的不协调和在不同动态平衡条件中所采取的不同运动方式和代偿策略.
